Illinois Compiled Statutes

Information maintained by the Legislative Reference Bureau
Updating the database of the Illinois Compiled Statutes (ILCS) is an ongoing process. Recent laws may not yet be included in the ILCS database, but they are found on this site as Public Acts soon after they become law. For information concerning the relationship between statutes and Public Acts, refer to the Guide.

Because the statute database is maintained primarily for legislative drafting purposes, statutory changes are sometimes included in the statute database before they take effect. If the source note at the end of a Section of the statutes includes a Public Act that has not yet taken effect, the version of the law that is currently in effect may have already been removed from the database and you should refer to that Public Act to see the changes made to the current law.

35 ILCS 200/15-10

    (35 ILCS 200/15-10)
    Sec. 15-10. Exempt property; procedures for certification.
    (a) All property granted an exemption by the Department pursuant to the requirements of Section 15-5 and described in the Sections following Section 15-30 and preceding Section 16-5, to the extent therein limited, is exempt from taxation. In order to maintain that exempt status, the titleholder or the owner of the beneficial interest of any property that is exempt must file with the chief county assessment officer, on or before January 31 of each year (May 31 in the case of property exempted by Section 15-170), an affidavit stating whether there has been any change in the ownership or use of the property, the status of the owner-resident, the satisfaction by a relevant hospital entity of the condition for an exemption under Section 15-86, or that a veteran with a disability who qualifies under Section 15-165 owned and used the property as of January 1 of that year. The nature of any change shall be stated in the affidavit. Failure to file an affidavit shall, in the discretion of the assessment officer, constitute cause to terminate the exemption of that property, notwithstanding any other provision of this Code. Owners of 5 or more such exempt parcels within a county may file a single annual affidavit in lieu of an affidavit for each parcel. The assessment officer, upon request, shall furnish an affidavit form to the owners, in which the owner may state whether there has been any change in the ownership or use of the property or status of the owner or resident as of January 1 of that year. The owner of 5 or more exempt parcels shall list all the properties giving the same information for each parcel as required of owners who file individual affidavits.
    (b) However, titleholders or owners of the beneficial interest in any property exempted under any of the following provisions are not required to submit an annual filing under this Section:
        (1) Section 15-45 (burial grounds) in counties of
    
less than 3,000,000 inhabitants and owned by a not-for-profit organization.
        (2) Section 15-40.
        (3) Section 15-50 (United States property).
    (c) If there is a change in use or ownership, however, notice must be filed pursuant to Section 15-20.
    (d) An application for homestead exemptions shall be filed as provided in Section 15-170 (senior citizens homestead exemption), Section 15-172 (senior citizens assessment freeze homestead exemption), and Sections 15-175 (general homestead exemption), 15-176 (general alternative homestead exemption), and 15-177 (long-time occupant homestead exemption), respectively.
    (e) For purposes of determining satisfaction of the condition for an exemption under Section 15-86:
        (1) The "year for which exemption is sought" is the
    
year prior to the year in which the affidavit is due.
        (2) The "hospital year" is the fiscal year of the
    
relevant hospital entity, or the fiscal year of one of the hospitals in the hospital system if the relevant hospital entity is a hospital system with members with different fiscal years, that ends in the year prior to the year in which the affidavit is due. However, if that fiscal year ends 3 months or less before the date on which the affidavit is due, the relevant hospital entity shall file an interim affidavit based on the currently available information, and shall file a supplemental affidavit within 90 days of date on which the application was due, if the information in the relevant hospital entity's audited financial statements changes the interim affidavit's statement concerning the entity's compliance with the calculation required by Section 15-86.
        (3) The affidavit shall be accompanied by an exhibit
    
prepared by the relevant hospital entity showing (A) the value of the relevant hospital entity's services and activities, if any, under items (1) through (7) of subsection (e) of Section 15-86, stated separately for each item, and (B) the value relating to the relevant hospital entity's estimated property tax liability under paragraphs (A), (B), and (C) of item (1) of subsection (g) of Section 15-86; under paragraphs (A), (B), and (C) of item (2) of subsection (g) of Section 15-86; and under item (3) of subsection (g) of Section 15-86.

35 ILCS 200/15-15

    (35 ILCS 200/15-15)
    Sec. 15-15. Obligation to file copies of leases or agreements. If any property listed as exempt by the chief county assessment officer is leased, loaned or otherwise made available for profit, the titleholder or the owner of the beneficial interest shall file with the assessment officer a copy of all such leases or agreements and a complete description of the premises, so the chief county assessment officer can ascertain the exact size and location of the premises in order to create a tax parcel. Failure to file such leases, agreements or descriptions shall, in the discretion of the chief county assessment officer, constitute cause to terminate the exemption, notwithstanding any other provision of this Code.

35 ILCS 200/15-20

    (35 ILCS 200/15-20)
    Sec. 15-20. Notification requirements after change in use or ownership. If any property listed as exempt by the chief county assessment officer has a change in use, a change in leasehold estate, or a change in titleholder of record by purchase, grant, taking or transfer, it is the obligation of the transferee to notify the chief county assessment officer in writing within 90 days of the change. If mailed, the notice shall be sent by certified mail, return receipt requested, and shall include the name and address of the taxpayer, the legal description of the property, the address of the property, and the permanent index number of the property where such number exists. If notice is provided in person, it shall be provided on a form prescribed by the chief county assessment officer, and the chief county assessment officer shall provide a date stamped copy of the notice. Except as provided in item (6) of subsection (a) of Section 9-260, item (6) of Section 16-135, and item (6) of Section 16-140 of this Code, if the failure to give such notification results in the assessment officer listing the property as exempt in subsequent years, the property shall be considered omitted property for purposes of this Code.

35 ILCS 200/15-25

    (35 ILCS 200/15-25)
    Sec. 15-25. Removal of exemptions. If the Department determines that any property has been unlawfully exempted from taxation, or is no longer entitled to exemption, the Department shall, before January 1 of any year, direct the chief county assessment officer to assess the property and return it to the assessment rolls for the next assessment year. The Department shall give notice of its decision to the owner of the property by certified mail. The decision shall be subject to review and hearing under Section 8-35, upon application by the owner filed within 60 days after the notice of decision is mailed. However, the extension of taxes on the assessment shall not be delayed by any proceedings under this Section. If the property is determined to be exempt, any taxes extended upon the assessment shall be abated or, if already paid, be refunded.
(Source: P.A. 95-331, eff. 8-21-07.)

35 ILCS 200/15-30

    (35 ILCS 200/15-30)
    Sec. 15-30. Payment to taxing districts for services. Any taxing district may enter into a mutually acceptable agreement with the owner of any exempt property whereby the owner agrees to make payments to the taxing district for the direct and indirect cost of services provided by the district. However, an agreement is not required to establish tax exempt status for the property, nor shall a taxing district use the absence of an agreement to defer or delay zoning changes, site exceptions from zoning, or other administrative measures to coerce an owner of property exempt from taxation to enter into an agreement to make voluntary payments in lieu of property taxes for the direct or indirect costs of services provided by the taxing district. However, any such zoning change, site exception from zoning, or other variance or special use granted by a municipality shall be reversed and returned to its prior status if the property is acquired by a taxable entity or used for a taxable purpose within 10 years after the change in zoning, site exception from zoning, or other variance or special use is granted. No agreement may be of more than 5 years duration, survive a change of use, or require payments in excess of taxes reasonably calculated to be due if such an agreement were not in effect and the property were not granted an exemption. An agreement may be renewed for periods of no more than 5 years.

    Sec. 15-35. Schools. All property donated by the United States for school purposes, and all property of schools, not sold or leased or otherwise used with a view to profit, is exempt, whether owned by a resident or non-resident of this State or by a corporation incorporated in any state of the United States. Also exempt is:
        (a) property of schools which is leased to a

        (e) property owned by a school district. The
    
exemption under this subsection is not affected by any transaction in which, for the purpose of obtaining financing, the school district, directly or indirectly, leases or otherwise transfers the property to another for which or whom property is not exempt and immediately after the lease or transfer enters into a leaseback or other agreement that directly or indirectly gives the school district a right to use, control, and possess the property. In the case of a conveyance of the property, the school district must retain an option to purchase the property at a future date or, within the limitations period for reverters, the property must revert back to the school district.
            (1) If the property has been conveyed as
        
described in this subsection, the property is no longer exempt under this Section as of the date when:
                (A) the right of the school district to use,
            
control, and possess the property is terminated;
                (B) the school district no longer has an
            
option to purchase or otherwise acquire the property; and

            (2) Pursuant to Sections 15-15 and 15-20 of this
        
Code, the school district shall notify the chief county assessment officer of any transaction under this subsection. The chief county assessment officer shall determine initial and continuing compliance with the requirements of this subsection for tax exemption. Failure to notify the chief county assessment officer of a transaction under this subsection or to otherwise comply with the requirements of Sections 15-15 and 15-20 of this Code shall, in the discretion of the chief county assessment officer, constitute cause to terminate the exemption, notwithstanding any other provision of this Code.
            (3) No provision of this subsection shall be
        
construed to affect the obligation of the school district to which an exemption certificate has been issued under this Section from its obligation under Section 15-10 of this Code to file an annual certificate of status or to notify the chief county assessment officer of transfers of interest or other changes in the status of the property as required by this Code.
            (4) The changes made by this amendatory Act of
        
the 91st General Assembly are declarative of existing law and shall not be construed as a new enactment; and
        (f) in counties with more than 200,000 inhabitants

developmental disability, and not-for-profit organizations providing services or facilities related to the goals of educational, social and physical development, if, upon making application for the exemption, the applicant provides affirmative evidence that the home or facility or organization is an exempt organization under paragraph (3) of Section 501(c) of the Internal Revenue Code or its successor, and either: (i) the bylaws of the home or facility or not-for-profit organization provide for a waiver or reduction, based on an individual's ability to pay, of any entrance fee, assignment of assets, or fee for services, or (ii) the home or facility is qualified, built or financed under Section 202 of the National Housing Act of 1959, as amended.
        An applicant that has been granted an exemption under
    
this subsection on the basis that its bylaws provide for a waiver or reduction, based on an individual's ability to pay, of any entrance fee, assignment of assets, or fee for services may be periodically reviewed by the Department to determine if the waiver or reduction was a past policy or is a current policy. The Department may revoke the exemption if it finds that the policy for waiver or reduction is no longer current.
        If a not-for-profit organization leases property that
    
is otherwise exempt under this subsection to an organization that conducts an activity on the leased premises that would entitle the lessee to an exemption from real estate taxes if the lessee were the owner of the property, then the leased property is exempt.
        (d) Not-for-profit health maintenance organizations
    
certified by the Director of the Illinois Department of Insurance under the Health Maintenance Organization Act, including any health maintenance organization that provides services to members at prepaid rates approved by the Illinois Department of Insurance if the membership of the organization is sufficiently large or of indefinite classes so that the community is benefited by its operation. No exemption shall apply to any hospital or health maintenance organization which has been adjudicated by a court of competent jurisdiction to have denied admission to any person because of race, color, creed, sex or national origin.
        (e) All free public libraries.
        (f) Historical societies.
    Property otherwise qualifying for an exemption under this Section shall not lose its exemption because the legal title is held (i) by an entity that is organized solely to hold that title and that qualifies under paragraph (2) of Section 501(c) of the Internal Revenue Code or its successor, whether or not that entity receives rent from the charitable organization for the repair and maintenance of the property, (ii) by an entity that is organized as a partnership or limited liability company, in which the charitable organization, or an affiliate or subsidiary of the charitable organization, is a general partner of the partnership or managing member of the limited liability company, for the purposes of owning and operating a residential rental property that has received an allocation of Low Income Housing Tax Credits for 100% of the dwelling units under Section 42 of the Internal Revenue Code of 1986, as amended, or (iii) for any assessment year including and subsequent to January 1, 1996 for which an application for exemption has been filed and a decision on which has not become final and nonappealable, by a limited liability company organized under the Limited Liability Company Act provided that (A) the limited liability company's sole member or members, as that term is used in Section 1-5 of the Limited Liability Company Act, are the institutions of public charity that actually and exclusively use the property for charitable and beneficent purposes; (B) the limited liability company is a disregarded entity for federal and Illinois income tax purposes and, as a result, the limited liability company is deemed exempt from income tax liability by virtue of the Internal Revenue Code Section 501(c)(3) status of its sole member or members; and (C) the limited liability company does not lease the property or otherwise use it with a view to profit.

35 ILCS 200/15-86

    (35 ILCS 200/15-86)
    Sec. 15-86. Exemptions related to access to hospital and health care services by low-income and underserved individuals.
    (a) The General Assembly finds:
        (1) Despite the Supreme Court's decision in Provena Covenant Medical Center v. Dept. of Revenue, 236
    
Ill.2d 368, there is considerable uncertainty surrounding the test for charitable property tax exemption, especially regarding the application of a quantitative or monetary threshold. In Provena, the Department stated that the primary basis for its decision was the hospital's inadequate amount of charitable activity, but the Department has not articulated what constitutes an adequate amount of charitable activity. After Provena, the Department denied property tax exemption applications of 3 more hospitals, and, on the effective date of this amendatory Act of the 97th General Assembly, at least 20 other hospitals are awaiting rulings on applications for property tax exemption.
        (2) In Provena, two Illinois Supreme Court justices opined
    
that "setting a monetary or quantum standard is a complex decision which should be left to our legislature, should it so choose". The Appellate Court in Provena stated: "The language we use in the State of Illinois to determine whether real property is used for a charitable purpose has its genesis in our 1870 Constitution. It is obvious that such language may be difficult to apply to the modern face of our nation's health care delivery systems". The court noted the many significant changes in the health care system since that time, but concluded that taking these changes into account is a matter of public policy, and "it is the legislature's job, not ours, to make public policy".
        (3) It is essential to ensure that tax exemption law
    
relating to hospitals accounts for the complexities of the modern health care delivery system. Health care is moving beyond the walls of the hospital. In addition to treating individual patients, hospitals are assuming responsibility for improving the health status of communities and populations. Low-income and underserved communities benefit disproportionately by these activities.
        (4) The Supreme Court has explained that: "the
    
fundamental ground upon which all exemptions in favor of charitable institutions are based is the benefit conferred upon the public by them, and a consequent relief, to some extent, of the burden upon the state to care for and advance the interests of its citizens". Hospitals relieve the burden of government in many ways, but most significantly through their participation in and substantial financial subsidization of the Illinois Medicaid program, which could not operate without the participation and partnership of Illinois hospitals.
        (5) Working with the Illinois hospital community and
    
other interested parties, the General Assembly has developed a comprehensive combination of related legislation that addresses hospital property tax exemption, significantly increases access to free health care for indigent persons, and strengthens the Medical Assistance program. It is the intent of the General Assembly to establish a new category of ownership for charitable property tax exemption to be applied to not-for-profit hospitals and hospital affiliates in lieu of the existing ownership category of "institutions of public charity". It is also the intent of the General Assembly to establish quantifiable standards for the issuance of charitable exemptions for such property. It is not the intent of the General Assembly to declare any property exempt ipso facto, but rather to establish criteria to be applied to the facts on a case-by-case basis.
    (b) For the purpose of this Section and Section 15-10, the following terms shall have the meanings set forth below:
        (1) "Hospital" means any institution, place,
    
building, buildings on a campus, or other health care facility located in Illinois that is licensed under the Hospital Licensing Act and has a hospital owner.
        (2) "Hospital owner" means a not-for-profit
    
corporation that is the titleholder of a hospital, or the owner of the beneficial interest in an Illinois land trust that is the titleholder of a hospital.
        (3) "Hospital affiliate" means any corporation,
    
partnership, limited partnership, joint venture, limited liability company, association or other organization, other than a hospital owner, that directly or indirectly controls, is controlled by, or is under common control with one or more hospital owners and that supports, is supported by, or acts in furtherance of the exempt health care purposes of at least one of those hospital owners' hospitals.
        (4) "Hospital system" means a hospital and one or
    
more other hospitals or hospital affiliates related by common control or ownership.
        (5) "Control" relating to hospital owners, hospital
    
affiliates, or hospital systems means possession, direct or indirect, of the power to direct or cause the direction of the management and policies of the entity, whether through ownership of assets, membership interest, other voting or governance rights, by contract or otherwise.
        (6) "Hospital applicant" means a hospital owner or
    
hospital affiliate that files an application for a property tax exemption pursuant to Section 15-5 and this Section.
        (7) "Relevant hospital entity" means (A) the hospital
    
owner, in the case of a hospital applicant that is a hospital owner, and (B) at the election of a hospital applicant that is a hospital affiliate, either (i) the hospital affiliate or (ii) the hospital system to which the hospital applicant belongs, including any hospitals or hospital affiliates that are related by common control or ownership.
        (8) "Subject property" means property for which a
    
hospital applicant files an application for an exemption pursuant to Section 15-5 and this Section.
        (9) "Hospital year" means the fiscal year of the
    
relevant hospital entity, or the fiscal year of one of the hospital owners in the hospital system if the relevant hospital entity is a hospital system with members with different fiscal years, that ends in the year for which the exemption is sought.
    (c) A hospital applicant satisfies the conditions for an exemption under this Section with respect to the subject property, and shall be issued a charitable exemption for that property, if the value of services or activities listed in subsection (e) for the hospital year equals or exceeds the relevant hospital entity's estimated property tax liability, as determined under subsection (g), for the year for which exemption is sought. For purposes of making the calculations required by this subsection (c), if the relevant hospital entity is a hospital owner that owns more than one hospital, the value of the services or activities listed in subsection (e) shall be calculated on the basis of only those services and activities relating to the hospital that includes the subject property, and the relevant hospital entity's estimated property tax liability shall be calculated only with respect to the properties comprising that hospital. In the case of a multi-state hospital system or hospital affiliate, the value of the services or activities listed in subsection (e) shall be calculated on the basis of only those services and activities that occur in Illinois and the relevant hospital entity's estimated property tax liability shall be calculated only with respect to its property located in Illinois.
    Notwithstanding any other provisions of this Act, any parcel or portion thereof, that is owned by a for-profit entity whether part of the hospital system or not, or that is leased, licensed or operated by a for-profit entity regardless of whether healthcare services are provided on that parcel shall not qualify for exemption. If a parcel has both exempt and non-exempt uses, an exemption may be granted for the qualifying portion of that parcel. In the case of parking lots and common areas serving both exempt and non-exempt uses those parcels or portions thereof may qualify for an exemption in proportion to the amount of qualifying use.
    (d) The hospital applicant shall include information in its exemption application establishing that it satisfies the requirements of subsection (c). For purposes of making the calculations required by subsection (c), the hospital applicant may for each year elect to use either (1) the value of the services or activities listed in subsection (e) for the hospital year or (2) the average value of those services or activities for the 3 fiscal years ending with the hospital year. If the relevant hospital entity has been in operation for less than 3 completed fiscal years, then the latter calculation, if elected, shall be performed on a pro rata basis.
    (e) Services that address the health care needs of low-income or underserved individuals or relieve the burden of government with regard to health care services. The following services and activities shall be considered for purposes of making the calculations required by subsection (c):
        (1) Charity care. Free or discounted services
    
provided pursuant to the relevant hospital entity's financial assistance policy, measured at cost, including discounts provided under the Hospital Uninsured Patient Discount Act.
        (2) Health services to low-income and underserved
    
individuals. Other unreimbursed costs of the relevant hospital entity for providing without charge, paying for, or subsidizing goods, activities, or services for the purpose of addressing the health of low-income or underserved individuals. Those activities or services may include, but are not limited to: financial or in-kind support to affiliated or unaffiliated hospitals, hospital affiliates, community clinics, or programs that treat low-income or underserved individuals; paying for or subsidizing health care professionals who care for low-income or underserved individuals; providing or subsidizing outreach or educational services to low-income or underserved individuals for disease management and prevention; free or subsidized goods, supplies, or services needed by low-income or underserved individuals because of their medical condition; and prenatal or childbirth outreach to low-income or underserved persons.
        (3) Subsidy of State or local governments. Direct or
    
indirect financial or in-kind subsidies of State or local governments by the relevant hospital entity that pay for or subsidize activities or programs related to health care for low-income or underserved individuals.
        (4) Support for State health care programs for
    
low-income individuals. At the election of the hospital applicant for each applicable year, either (A) 10% of payments to the relevant hospital entity and any hospital affiliate designated by the relevant hospital entity (provided that such hospital affiliate's operations provide financial or operational support for or receive financial or operational support from the relevant hospital entity) under Medicaid or other means-tested programs, including, but not limited to, General Assistance, the Covering ALL KIDS Health Insurance Act, and the State Children's Health Insurance Program or (B) the amount of subsidy provided by the relevant hospital entity and any hospital affiliate designated by the relevant hospital entity (provided that such hospital affiliate's operations provide financial or operational support for or receive financial or operational support from the relevant hospital entity) to State or local government in treating Medicaid recipients and recipients of means-tested programs, including but not limited to General Assistance, the Covering ALL KIDS Health Insurance Act, and the State Children's Health Insurance Program. The amount of subsidy for purposes of this item (4) is calculated in the same manner as unreimbursed costs are calculated for Medicaid and other means-tested government programs in the Schedule H of IRS Form 990 in effect on the effective date of this amendatory Act of the 97th General Assembly; provided, however, that in any event unreimbursed costs shall be net of fee-for-services payments, payments pursuant to an assessment, quarterly payments, and all other payments included on the schedule H of the IRS form 990.
        (5) Dual-eligible subsidy. The amount of subsidy
    
provided to government by treating dual-eligible Medicare/Medicaid patients. The amount of subsidy for purposes of this item (5) is calculated by multiplying the relevant hospital entity's unreimbursed costs for Medicare, calculated in the same manner as determined in the Schedule H of IRS Form 990 in effect on the effective date of this amendatory Act of the 97th General Assembly, by the relevant hospital entity's ratio of dual-eligible patients to total Medicare patients.
        (6) Relief of the burden of government related to
    
health care of low-income individuals. Except to the extent otherwise taken into account in this subsection, the portion of unreimbursed costs of the relevant hospital entity attributable to providing, paying for, or subsidizing goods, activities, or services that relieve the burden of government related to health care for low-income individuals. Such activities or services shall include, but are not limited to, providing emergency, trauma, burn, neonatal, psychiatric, rehabilitation, or other special services; providing medical education; and conducting medical research or training of health care professionals. The portion of those unreimbursed costs attributable to benefiting low-income individuals shall be determined using the ratio calculated by adding the relevant hospital entity's costs attributable to charity care, Medicaid, other means-tested government programs, Medicare patients with disabilities under age 65, and dual-eligible Medicare/Medicaid patients and dividing that total by the relevant hospital entity's total costs. Such costs for the numerator and denominator shall be determined by multiplying gross charges by the cost to charge ratio taken from the hospitals' most recently filed Medicare cost report (CMS 2252-10 Worksheet C, Part I). In the case of emergency services, the ratio shall be calculated using costs (gross charges multiplied by the cost to charge ratio taken from the hospitals' most recently filed Medicare cost report (CMS 2252-10 Worksheet C, Part I)) of patients treated in the relevant hospital entity's emergency department.
        (7) Any other activity by the relevant hospital
    
entity that the Department determines relieves the burden of government or addresses the health of low-income or underserved individuals.
    (f) For purposes of making the calculations required by subsections (c) and (e):
        (1) particular services or activities eligible for
    
consideration under any of the paragraphs (1) through (7) of subsection (e) may not be counted under more than one of those paragraphs; and
        (2) the amount of unreimbursed costs and the amount
    
of subsidy shall not be reduced by restricted or unrestricted payments received by the relevant hospital entity as contributions deductible under Section 170(a) of the Internal Revenue Code.
    (g) Estimation of Exempt Property Tax Liability. The estimated property tax liability used for the determination in subsection (c) shall be calculated as follows:
        (1) "Estimated property tax liability" means the
    
estimated dollar amount of property tax that would be owed, with respect to the exempt portion of each of the relevant hospital entity's properties that are already fully or partially exempt, or for which an exemption in whole or in part is currently being sought, and then aggregated as applicable, as if the exempt portion of those properties were subject to tax, calculated with respect to each such property by multiplying:
            (A) the lesser of (i) the actual assessed value,
        
if any, of the portion of the property for which an exemption is sought or (ii) an estimated assessed value of the exempt portion of such property as determined in item (2) of this subsection (g), by:
            (B) the applicable State equalization rate
        
(yielding the equalized assessed value), by
            (C) the applicable tax rate.
        (2) The estimated assessed value of the exempt
    
portion of the property equals the sum of (i) the estimated fair market value of buildings on the property, as determined in accordance with subparagraphs (A) and (B) of this item (2), multiplied by the applicable assessment factor, and (ii) the estimated assessed value of the land portion of the property, as determined in accordance with subparagraph (C).
            (A) The "estimated fair market value of buildings
        
on the property" means the replacement value of any exempt portion of buildings on the property, minus depreciation, determined utilizing the cost replacement method whereby the exempt square footage of all such buildings is multiplied by the replacement cost per square foot for Class A Average building found in the most recent edition of the Marshall & Swift Valuation Services Manual, adjusted by any appropriate current cost and local multipliers.
            (B) Depreciation, for purposes of calculating the
        
estimated fair market value of buildings on the property, is applied by utilizing a weighted mean life for the buildings based on original construction and assuming a 40-year life for hospital buildings and the applicable life for other types of buildings as specified in the American Hospital Association publication "Estimated Useful Lives of Depreciable Hospital Assets". In the case of hospital buildings, the remaining life is divided by 40 and this ratio is multiplied by the replacement cost of the buildings to obtain an estimated fair market value of buildings. If a hospital building is older than 35 years, a remaining life of 5 years for residual value is assumed; and if a building is less than 8 years old, a remaining life of 32 years is assumed.
            (C) The estimated assessed value of the land
        
portion of the property shall be determined by multiplying (i) the per square foot average of the assessed values of three parcels of land (not including farm land, and excluding the assessed value of the improvements thereon) reasonably comparable to the property, by (ii) the number of square feet comprising the exempt portion of the property's land square footage.
        (3) The assessment factor, State equalization rate,
    
and tax rate (including any special factors such as Enterprise Zones) used in calculating the estimated property tax liability shall be for the most recent year that is publicly available from the applicable chief county assessment officer or officers at least 90 days before the end of the hospital year.
        (4) The method utilized to calculate estimated
    
property tax liability for purposes of this Section 15-86 shall not be utilized for the actual valuation, assessment, or taxation of property pursuant to the Property Tax Code.
    (h) Application. Each hospital applicant applying for a property tax exemption pursuant to Section 15-5 and this Section shall use an application form provided by the Department. The application form shall specify the records required in support of the application and those records shall be submitted to the Department with the application form. Each application or affidavit shall contain a verification by the Chief Executive Officer of the hospital applicant under oath or affirmation stating that each statement in the application or affidavit and each document submitted with the application or affidavit are true and correct. The records submitted with the application pursuant to this Section shall include an exhibit prepared by the relevant hospital entity showing (A) the value of the relevant hospital entity's services and activities, if any, under paragraphs (1) through (7) of subsection (e) of this Section stated separately for each paragraph, and (B) the value relating to the relevant hospital entity's estimated property tax liability under subsections (g)(1)(A), (B), and (C), subsections (g)(2)(A), (B), and (C), and subsection (g)(3) of this Section stated separately for each item. Such exhibit will be made available to the public by the chief county assessment officer. Nothing in this Section shall be construed as limiting the Attorney General's authority under the Illinois False Claims Act.
    (i) Nothing in this Section shall be construed to limit the ability of otherwise eligible hospitals, hospital owners, hospital affiliates, or hospital systems to obtain or maintain property tax exemptions pursuant to a provision of the Property Tax Code other than this Section.

For purposes of this Section alone, the Regional Transportation Authority, any service board or division of the Regional Transportation Authority, the Northeast Illinois Regional Commuter Railroad Corporation, the Chicago Transit Authority, or a municipal corporation, as defined in item (i), shall be deemed an "eligible transportation authority". The exemption provided in this subsection shall not be affected by any transaction in which, for the purpose of obtaining financing, the eligible transportation authority, directly or indirectly, leases or otherwise transfers such property to another whose property is not exempt and immediately thereafter enters into a leaseback or other agreement that directly or indirectly gives the eligible transportation authority a right to use, control, and possess the property. In the case of a conveyance of such property, the eligible transportation authority must retain an option to purchase the property at a future date or, within the limitations period for reverters, the property must revert back to the eligible transportation authority.
    (c) If such property has been conveyed as described in subsection (b), the property will no longer be exempt pursuant to this Section as of the date when:

authority to use, control, and possess the property has been terminated;
        (2) the eligible transportation authority no longer
    
has an option to purchase or otherwise acquire the property; and
        (3) there is no provision for a reverter of the
    
property to the eligible transportation authority within the limitations period for reverters.
    (d) Pursuant to Sections 15-15 and 15-20 of this Code, the eligible transportation authority shall notify the chief county assessment officer of any transaction under subsection (b) of this Section. The chief county assessment officer shall determine initial and continuing compliance with the requirements of this Section for tax exemption. Failure to notify the chief county assessment officer of a transaction under this Section or to otherwise comply with the requirements of Sections 15-15 and 15-20 of this Code shall, in the discretion of the chief county assessment officer, constitute cause to terminate the exemption, notwithstanding any other provision of this Code.
    (e) No provision of this Section shall be construed to affect the obligation of the eligible transportation authority to which an exemption certificate has been issued under this Section from its obligation under Section 15-10 of this Code to file an annual certificate of status or to notify the chief county assessment officer of transfers of interest or other changes in the status of the property as required by this Code.
    (f) The changes made by this amendatory Act of 1997 are declarative of existing law and shall not be construed as a new enactment.

    Sec. 15-165. Veterans with disabilities. Property up to an assessed value of $100,000, owned and used exclusively by a veteran with a disability, or the spouse or unmarried surviving spouse of the veteran, as a home, is exempt. As used in this Section, a "veteran with a disability" means a person who has served in the Armed Forces of the United States and whose disability is of such a nature that the Federal Government has authorized payment for purchase or construction of Specially Adapted Housing as set forth in the United States Code, Title 38, Chapter 21, Section 2101.
    The exemption applies to housing where Federal funds have been used to purchase or construct special adaptations to suit the veteran's disability.
    The exemption also applies to housing that is specially adapted to suit the veteran's disability, and purchased entirely or in part by the proceeds of a sale, casualty loss reimbursement, or other transfer of a home for which the Federal Government had previously authorized payment for purchase or construction as Specially Adapted Housing.
    However, the entire proceeds of the sale, casualty loss reimbursement, or other transfer of that housing shall be applied to the acquisition of subsequent specially adapted housing to the extent that the proceeds equal the purchase price of the subsequently acquired housing.
    Beginning with the 2015 tax year, the exemption also applies to housing that is specifically constructed or adapted to suit a qualifying veteran's disability if the housing or adaptations are donated by a charitable organization, the veteran has been approved to receive funds for the purchase or construction of Specially Adapted Housing under Title 38, Chapter 21, Section 2101 of the United States Code, and the home has been inspected and certified by a licensed home inspector to be in compliance with applicable standards set forth in U.S. Department of Veterans Affairs, Veterans Benefits Administration Pamphlet 26-13 Handbook for Design of Specially Adapted Housing.
    For purposes of this Section, "charitable organization" means any benevolent, philanthropic, patriotic, or eleemosynary entity that solicits and collects funds for charitable purposes and includes each local, county, or area division of that charitable organization.
    For purposes of this Section, "unmarried surviving spouse" means the surviving spouse of the veteran at any time after the death of the veteran during which such surviving spouse is not married.
    This exemption must be reestablished on an annual basis by certification from the Illinois Department of Veterans' Affairs to the Department, which shall forward a copy of the certification to local assessing officials.
    A taxpayer who claims an exemption under Section 15-168 or 15-169 may not claim an exemption under this Section.

    (35 ILCS 200/15-167)
    Sec. 15-167. Returning Veterans' Homestead Exemption.
    (a) Beginning with taxable year 2007, a homestead exemption, limited to a reduction set forth under subsection (b), from the property's value, as equalized or assessed by the Department, is granted for property that is owned and occupied as the principal residence of a veteran returning from an armed conflict involving the armed forces of the United States who is liable for paying real estate taxes on the property and is an owner of record of the property or has a legal or equitable interest therein as evidenced by a written instrument, except for a leasehold interest, other than a leasehold interest of land on which a single family residence is located, which is occupied as the principal residence of a veteran returning from an armed conflict involving the armed forces of the United States who has an ownership interest therein, legal, equitable or as a lessee, and on which he or she is liable for the payment of property taxes. For purposes of the exemption under this Section, "veteran" means an Illinois resident who has served as a member of the United States Armed Forces, a member of the Illinois National Guard, or a member of the United States Reserve Forces.
    (b) In all counties, the reduction is $5,000 for the taxable year in which the veteran returns from active duty in an armed conflict involving the armed forces of the United States; however, if the veteran first acquires his or her principal residence during the taxable year in which he or she returns, but after January 1 of that year, and if the property is owned and occupied by the veteran as a principal residence on January 1 of the next taxable year, he or she may apply the exemption for the next taxable year, and only the next taxable year, after he or she returns. Beginning in taxable year 2010, the reduction shall also be allowed for the taxable year after the taxable year in which the veteran returns from active duty in an armed conflict involving the armed forces of the United States. For land improved with an apartment building owned and operated as a cooperative, the maximum reduction from the value of the property, as equalized by the Department, must be multiplied by the number of apartments or units occupied by a veteran returning from an armed conflict involving the armed forces of the United States who is liable, by contract with the owner or owners of record, for paying property taxes on the property and is an owner of record of a legal or equitable interest in the cooperative apartment building, other than a leasehold interest. In a cooperative where a homestead exemption has been granted, the cooperative association or the management firm of the cooperative or facility shall credit the savings resulting from that exemption only to the apportioned tax liability of the owner or resident who qualified for the exemption. Any person who willfully refuses to so credit the savings is guilty of a Class B misdemeanor.
    (c) Application must be made during the application period in effect for the county of his or her residence. The assessor or chief county assessment officer may determine the eligibility of residential property to receive the homestead exemption provided by this Section by application, visual inspection, questionnaire, or other reasonable methods. The determination must be made in accordance with guidelines established by the Department.
    (d) The exemption under this Section is in addition to any other homestead exemption provided in this Article 15. Notwithstanding Sections 6 and 8 of the State Mandates Act, no reimbursement by the State is required for the implementation of any mandate created by this Section.

    Sec. 15-168. Homestead exemption for persons with disabilities.
    (a) Beginning with taxable year 2007, an annual homestead exemption is granted to persons with disabilities in the amount of $2,000, except as provided in subsection (c), to be deducted from the property's value as equalized or assessed by the Department of Revenue. The person with a disability shall receive the homestead exemption upon meeting the following requirements:
        (1) The property must be occupied as the primary
    
residence by the person with a disability.
        (2) The person with a disability must be liable for
    
paying the real estate taxes on the property.
        (3) The person with a disability must be an owner of
    
record of the property or have a legal or equitable interest in the property as evidenced by a written instrument. In the case of a leasehold interest in property, the lease must be for a single family residence.
    A person who has a disability during the taxable year is eligible to apply for this homestead exemption during that taxable year. Application must be made during the application period in effect for the county of residence. If a homestead exemption has been granted under this Section and the person awarded the exemption subsequently becomes a resident of a facility licensed under the Nursing Home Care Act, the Specialized Mental Health Rehabilitation Act of 2013, the ID/DD Community Care Act, or the MC/DD Act, then the exemption shall continue (i) so long as the residence continues to be occupied by the qualifying person's spouse or (ii) if the residence remains unoccupied but is still owned by the person qualified for the homestead exemption.
    (b) For the purposes of this Section, "person with a disability" means a person unable to engage in any substantial gainful activity by reason of a medically determinable physical or mental impairment which can be expected to result in death or has lasted or can be expected to last for a continuous period of not less than 12 months. Persons with disabilities filing claims under this Act shall submit proof of disability in such form and manner as the Department shall by rule and regulation prescribe. Proof that a claimant is eligible to receive disability benefits under the Federal Social Security Act shall constitute proof of disability for purposes of this Act. Issuance of an Illinois Person with a Disability Identification Card stating that the claimant is under a Class 2 disability, as defined in Section 4A of the Illinois Identification Card Act, shall constitute proof that the person named thereon is a person with a disability for purposes of this Act. A person with a disability not covered under the Federal Social Security Act and not presenting an Illinois Person with a Disability Identification Card stating that the claimant is under a Class 2 disability shall be examined by a physician, advanced practice nurse, or physician assistant designated by the Department, and his status as a person with a disability determined using the same standards as used by the Social Security Administration. The costs of any required examination shall be borne by the claimant.
    (c) For land improved with (i) an apartment building owned and operated as a cooperative or (ii) a life care facility as defined under Section 2 of the Life Care Facilities Act that is considered to be a cooperative, the maximum reduction from the value of the property, as equalized or assessed by the Department, shall be multiplied by the number of apartments or units occupied by a person with a disability. The person with a disability shall receive the homestead exemption upon meeting the following requirements:
        (1) The property must be occupied as the primary
    
residence by the person with a disability.
        (2) The person with a disability must be liable by
    
contract with the owner or owners of record for paying the apportioned property taxes on the property of the cooperative or life care facility. In the case of a life care facility, the person with a disability must be liable for paying the apportioned property taxes under a life care contract as defined in Section 2 of the Life Care Facilities Act.
        (3) The person with a disability must be an owner of
    
record of a legal or equitable interest in the cooperative apartment building. A leasehold interest does not meet this requirement.
If a homestead exemption is granted under this subsection, the cooperative association or management firm shall credit the savings resulting from the exemption to the apportioned tax liability of the qualifying person with a disability. The chief county assessment officer may request reasonable proof that the association or firm has properly credited the exemption. A person who willfully refuses to credit an exemption to the qualified person with a disability is guilty of a Class B misdemeanor.
    (d) The chief county assessment officer shall determine the eligibility of property to receive the homestead exemption according to guidelines established by the Department. After a person has received an exemption under this Section, an annual verification of eligibility for the exemption shall be mailed to the taxpayer.
    In counties with fewer than 3,000,000 inhabitants, the chief county assessment officer shall provide to each person granted a homestead exemption under this Section a form to designate any other person to receive a duplicate of any notice of delinquency in the payment of taxes assessed and levied under this Code on the person's qualifying property. The duplicate notice shall be in addition to the notice required to be provided to the person receiving the exemption and shall be given in the manner required by this Code. The person filing the request for the duplicate notice shall pay an administrative fee of $5 to the chief county assessment officer. The assessment officer shall then file the executed designation with the county collector, who shall issue the duplicate notices as indicated by the designation. A designation may be rescinded by the person with a disability in the manner required by the chief county assessment officer.
    (e) A taxpayer who claims an exemption under Section 15-165 or 15-169 may not claim an exemption under this Section.

    Sec. 15-170. Senior citizens homestead exemption. An annual homestead exemption limited, except as described here with relation to cooperatives or life care facilities, to a maximum reduction set forth below from the property's value, as equalized or assessed by the Department, is granted for property that is occupied as a residence by a person 65 years of age or older who is liable for paying real estate taxes on the property and is an owner of record of the property or has a legal or equitable interest therein as evidenced by a written instrument, except for a leasehold interest, other than a leasehold interest of land on which a single family residence is located, which is occupied as a residence by a person 65 years or older who has an ownership interest therein, legal, equitable or as a lessee, and on which he or she is liable for the payment of property taxes. Before taxable year 2004, the maximum reduction shall be $2,500 in counties with 3,000,000 or more inhabitants and $2,000 in all other counties. For taxable years 2004 through 2005, the maximum reduction shall be $3,000 in all counties. For taxable years 2006 and 2007, the maximum reduction shall be $3,500. For taxable years 2008 through 2011, the maximum reduction is $4,000 in all counties. For taxable year 2012, the maximum reduction is $5,000 in counties with 3,000,000 or more inhabitants and $4,000 in all other counties. For taxable years 2013 through 2016, the maximum reduction is $5,000 in all counties. For taxable years 2017 and thereafter, the maximum reduction is $8,000 in counties with 3,000,000 or more inhabitants and $5,000 in all other counties.
    For land improved with an apartment building owned and operated as a cooperative, the maximum reduction from the value of the property, as equalized by the Department, shall be multiplied by the number of apartments or units occupied by a person 65 years of age or older who is liable, by contract with the owner or owners of record, for paying property taxes on the property and is an owner of record of a legal or equitable interest in the cooperative apartment building, other than a leasehold interest. For land improved with a life care facility, the maximum reduction from the value of the property, as equalized by the Department, shall be multiplied by the number of apartments or units occupied by persons 65 years of age or older, irrespective of any legal, equitable, or leasehold interest in the facility, who are liable, under a contract with the owner or owners of record of the facility, for paying property taxes on the property. In a cooperative or a life care facility where a homestead exemption has been granted, the cooperative association or the management firm of the cooperative or facility shall credit the savings resulting from that exemption only to the apportioned tax liability of the owner or resident who qualified for the exemption. Any person who willfully refuses to so credit the savings shall be guilty of a Class B misdemeanor. Under this Section and Sections 15-175, 15-176, and 15-177, "life care facility" means a facility, as defined in Section 2 of the Life Care Facilities Act, with which the applicant for the homestead exemption has a life care contract as defined in that Act.
    When a homestead exemption has been granted under this Section and the person qualifying subsequently becomes a resident of a facility licensed under the Assisted Living and Shared Housing Act, the Nursing Home Care Act, the Specialized Mental Health Rehabilitation Act of 2013, the ID/DD Community Care Act, or the MC/DD Act, the exemption shall continue so long as the residence continues to be occupied by the qualifying person's spouse if the spouse is 65 years of age or older, or if the residence remains unoccupied but is still owned by the person qualified for the homestead exemption.
    A person who will be 65 years of age during the current assessment year shall be eligible to apply for the homestead exemption during that assessment year. Application shall be made during the application period in effect for the county of his residence.
    Beginning with assessment year 2003, for taxes payable in 2004, property that is first occupied as a residence after January 1 of any assessment year by a person who is eligible for the senior citizens homestead exemption under this Section must be granted a pro-rata exemption for the assessment year. The amount of the pro-rata exemption is the exemption allowed in the county under this Section divided by 365 and multiplied by the number of days during the assessment year the property is occupied as a residence by a person eligible for the exemption under this Section. The chief county assessment officer must adopt reasonable procedures to establish eligibility for this pro-rata exemption.
    The assessor or chief county assessment officer may determine the eligibility of a life care facility to receive the benefits provided by this Section, by affidavit, application, visual inspection, questionnaire or other reasonable methods in order to insure that the tax savings resulting from the exemption are credited by the management firm to the apportioned tax liability of each qualifying resident. The assessor may request reasonable proof that the management firm has so credited the exemption.
    The chief county assessment officer of each county with less than 3,000,000 inhabitants shall provide to each person allowed a homestead exemption under this Section a form to designate any other person to receive a duplicate of any notice of delinquency in the payment of taxes assessed and levied under this Code on the property of the person receiving the exemption. The duplicate notice shall be in addition to the notice required to be provided to the person receiving the exemption, and shall be given in the manner required by this Code. The person filing the request for the duplicate notice shall pay a fee of $5 to cover administrative costs to the supervisor of assessments, who shall then file the executed designation with the county collector. Notwithstanding any other provision of this Code to the contrary, the filing of such an executed designation requires the county collector to provide duplicate notices as indicated by the designation. A designation may be rescinded by the person who executed such designation at any time, in the manner and form required by the chief county assessment officer.
    The assessor or chief county assessment officer may determine the eligibility of residential property to receive the homestead exemption provided by this Section by application, visual inspection, questionnaire or other reasonable methods. The determination shall be made in accordance with guidelines established by the Department.
    In counties with 3,000,000 or more inhabitants, beginning in taxable year 2010, each taxpayer who has been granted an exemption under this Section must reapply on an annual basis. The chief county assessment officer shall mail the application to the taxpayer. In counties with less than 3,000,000 inhabitants, the county board may by resolution provide that if a person has been granted a homestead exemption under this Section, the person qualifying need not reapply for the exemption.
    In counties with less than 3,000,000 inhabitants, if the assessor or chief county assessment officer requires annual application for verification of eligibility for an exemption once granted under this Section, the application shall be mailed to the taxpayer.
    The assessor or chief county assessment officer shall notify each person who qualifies for an exemption under this Section that the person may also qualify for deferral of real estate taxes under the Senior Citizens Real Estate Tax Deferral Act. The notice shall set forth the qualifications needed for deferral of real estate taxes, the address and telephone number of county collector, and a statement that applications for deferral of real estate taxes may be obtained from the county collector.
    Notwithstanding Sections 6 and 8 of the State Mandates Act, no reimbursement by the State is required for the implementation of any mandate created by this Section.

If in any subsequent taxable year for which the applicant applies and qualifies for the exemption the equalized assessed value of the residence is less than the equalized assessed value in the existing base year (provided that such equalized assessed value is not based on an assessed value that results from a temporary irregularity in the property that reduces the assessed value for one or more taxable years), then that subsequent taxable year shall become the base year until a new base year is established under the terms of this paragraph. For taxable year 1999 only, the Chief County Assessment Officer shall review (i) all taxable years for which the applicant applied and qualified for the exemption and (ii) the existing base year. The assessment officer shall select as the new base year the year with the lowest equalized assessed value. An equalized assessed value that is based on an assessed value that results from a temporary irregularity in the property that reduces the assessed value for one or more taxable years shall not be considered the lowest equalized assessed value. The selected year shall be the base year for taxable year 1999 and thereafter until a new base year is established under the terms of this paragraph.
    "Chief County Assessment Officer" means the County Assessor or Supervisor of Assessments of the county in which the property is located.
    "Equalized assessed value" means the assessed value as equalized by the Illinois Department of Revenue.
    "Household" means the applicant, the spouse of the applicant, and all persons using the residence of the applicant as their principal place of residence.

    "Taxable year" means the calendar year during which ad valorem property taxes payable in the next succeeding year are levied.
    (c) Beginning in taxable year 1994, a senior citizens assessment freeze homestead exemption is granted for real property that is improved with a permanent structure that is occupied as a residence by an applicant who (i) is 65 years of age or older during the taxable year, (ii) has a household income that does not exceed the maximum income limitation, (iii) is liable for paying real property taxes on the property, and (iv) is an owner of record of the property or has a legal or equitable interest in the property as evidenced by a written instrument. This homestead exemption shall also apply to a leasehold interest in a parcel of property improved with a permanent structure that is a single family residence that is occupied as a residence by a person who (i) is 65 years of age or older during the taxable year, (ii) has a household income that does not exceed the maximum income limitation, (iii) has a legal or equitable ownership interest in the property as lessee, and (iv) is liable for the payment of real property taxes on that property.
    In counties of 3,000,000 or more inhabitants, the amount of the exemption for all taxable years is the equalized assessed value of the residence in the taxable year for which application is made minus the base amount. In all other counties, the amount of the exemption is as follows: (i) through taxable year 2005 and for taxable year 2007 and thereafter, the amount of this exemption shall be the equalized assessed value of the residence in the taxable year for which application is made minus the base amount; and (ii) for taxable year 2006, the amount of the exemption is as follows:
        (1) For an applicant who has a household income of

exceeding $45,000 but not exceeding $46,250, the amount of the exemption is (i) the equalized assessed value of the residence in the taxable year for which application is made minus the base amount (ii) multiplied by 0.8.
        (3) For an applicant who has a household income
    
exceeding $46,250 but not exceeding $47,500, the amount of the exemption is (i) the equalized assessed value of the residence in the taxable year for which application is made minus the base amount (ii) multiplied by 0.6.
        (4) For an applicant who has a household income
    
exceeding $47,500 but not exceeding $48,750, the amount of the exemption is (i) the equalized assessed value of the residence in the taxable year for which application is made minus the base amount (ii) multiplied by 0.4.
        (5) For an applicant who has a household income
    
exceeding $48,750 but not exceeding $50,000, the amount of the exemption is (i) the equalized assessed value of the residence in the taxable year for which application is made minus the base amount (ii) multiplied by 0.2.
    When the applicant is a surviving spouse of an applicant for a prior year for the same residence for which an exemption under this Section has been granted, the base year and base amount for that residence are the same as for the applicant for the prior year.
    Each year at the time the assessment books are certified to the County Clerk, the Board of Review or Board of Appeals shall give to the County Clerk a list of the assessed values of improvements on each parcel qualifying for this exemption that were added after the base year for this parcel and that increased the assessed value of the property.
    In the case of land improved with an apartment building owned and operated as a cooperative or a building that is a life care facility that qualifies as a cooperative, the maximum reduction from the equalized assessed value of the property is limited to the sum of the reductions calculated for each unit occupied as a residence by a person or persons (i) 65 years of age or older, (ii) with a household income that does not exceed the maximum income limitation, (iii) who is liable, by contract with the owner or owners of record, for paying real property taxes on the property, and (iv) who is an owner of record of a legal or equitable interest in the cooperative apartment building, other than a leasehold interest. In the instance of a cooperative where a homestead exemption has been granted under this Section, the cooperative association or its management firm shall credit the savings resulting from that exemption only to the apportioned tax liability of the owner who qualified for the exemption. Any person who willfully refuses to credit that savings to an owner who qualifies for the exemption is guilty of a Class B misdemeanor.
    When a homestead exemption has been granted under this Section and an applicant then becomes a resident of a facility licensed under the Assisted Living and Shared Housing Act, the Nursing Home Care Act, the Specialized Mental Health Rehabilitation Act of 2013, the ID/DD Community Care Act, or the MC/DD Act, the exemption shall be granted in subsequent years so long as the residence (i) continues to be occupied by the qualified applicant's spouse or (ii) if remaining unoccupied, is still owned by the qualified applicant for the homestead exemption.
    Beginning January 1, 1997, when an individual dies who would have qualified for an exemption under this Section, and the surviving spouse does not independently qualify for this exemption because of age, the exemption under this Section shall be granted to the surviving spouse for the taxable year preceding and the taxable year of the death, provided that, except for age, the surviving spouse meets all other qualifications for the granting of this exemption for those years.
    When married persons maintain separate residences, the exemption provided for in this Section may be claimed by only one of such persons and for only one residence.
    For taxable year 1994 only, in counties having less than 3,000,000 inhabitants, to receive the exemption, a person shall submit an application by February 15, 1995 to the Chief County Assessment Officer of the county in which the property is located. In counties having 3,000,000 or more inhabitants, for taxable year 1994 and all subsequent taxable years, to receive the exemption, a person may submit an application to the Chief County Assessment Officer of the county in which the property is located during such period as may be specified by the Chief County Assessment Officer. The Chief County Assessment Officer in counties of 3,000,000 or more inhabitants shall annually give notice of the application period by mail or by publication. In counties having less than 3,000,000 inhabitants, beginning with taxable year 1995 and thereafter, to receive the exemption, a person shall submit an application by July 1 of each taxable year to the Chief County Assessment Officer of the county in which the property is located. A county may, by ordinance, establish a date for submission of applications that is different than July 1. The applicant shall submit with the application an affidavit of the applicant's total household income, age, marital status (and if married the name and address of the applicant's spouse, if known), and principal dwelling place of members of the household on January 1 of the taxable year. The Department shall establish, by rule, a method for verifying the accuracy of affidavits filed by applicants under this Section, and the Chief County Assessment Officer may conduct audits of any taxpayer claiming an exemption under this Section to verify that the taxpayer is eligible to receive the exemption. Each application shall contain or be verified by a written declaration that it is made under the penalties of perjury. A taxpayer's signing a fraudulent application under this Act is perjury, as defined in Section 32-2 of the Criminal Code of 2012. The applications shall be clearly marked as applications for the Senior Citizens Assessment Freeze Homestead Exemption and must contain a notice that any taxpayer who receives the exemption is subject to an audit by the Chief County Assessment Officer.
    Notwithstanding any other provision to the contrary, in counties having fewer than 3,000,000 inhabitants, if an applicant fails to file the application required by this Section in a timely manner and this failure to file is due to a mental or physical condition sufficiently severe so as to render the applicant incapable of filing the application in a timely manner, the Chief County Assessment Officer may extend the filing deadline for a period of 30 days after the applicant regains the capability to file the application, but in no case may the filing deadline be extended beyond 3 months of the original filing deadline. In order to receive the extension provided in this paragraph, the applicant shall provide the Chief County Assessment Officer with a signed statement from the applicant's physician, advanced practice nurse, or physician assistant stating the nature and extent of the condition, that, in the physician's, advanced practice nurse's, or physician assistant's opinion, the condition was so severe that it rendered the applicant incapable of filing the application in a timely manner, and the date on which the applicant regained the capability to file the application.
    Beginning January 1, 1998, notwithstanding any other provision to the contrary, in counties having fewer than 3,000,000 inhabitants, if an applicant fails to file the application required by this Section in a timely manner and this failure to file is due to a mental or physical condition sufficiently severe so as to render the applicant incapable of filing the application in a timely manner, the Chief County Assessment Officer may extend the filing deadline for a period of 3 months. In order to receive the extension provided in this paragraph, the applicant shall provide the Chief County Assessment Officer with a signed statement from the applicant's physician, advanced practice nurse, or physician assistant stating the nature and extent of the condition, and that, in the physician's, advanced practice nurse's, or physician assistant's opinion, the condition was so severe that it rendered the applicant incapable of filing the application in a timely manner.
    In counties having less than 3,000,000 inhabitants, if an applicant was denied an exemption in taxable year 1994 and the denial occurred due to an error on the part of an assessment official, or his or her agent or employee, then beginning in taxable year 1997 the applicant's base year, for purposes of determining the amount of the exemption, shall be 1993 rather than 1994. In addition, in taxable year 1997, the applicant's exemption shall also include an amount equal to (i) the amount of any exemption denied to the applicant in taxable year 1995 as a result of using 1994, rather than 1993, as the base year, (ii) the amount of any exemption denied to the applicant in taxable year 1996 as a result of using 1994, rather than 1993, as the base year, and (iii) the amount of the exemption erroneously denied for taxable year 1994.
    For purposes of this Section, a person who will be 65 years of age during the current taxable year shall be eligible to apply for the homestead exemption during that taxable year. Application shall be made during the application period in effect for the county of his or her residence.
    The Chief County Assessment Officer may determine the eligibility of a life care facility that qualifies as a cooperative to receive the benefits provided by this Section by use of an affidavit, application, visual inspection, questionnaire, or other reasonable method in order to insure that the tax savings resulting from the exemption are credited by the management firm to the apportioned tax liability of each qualifying resident. The Chief County Assessment Officer may request reasonable proof that the management firm has so credited that exemption.
    Except as provided in this Section, all information received by the chief county assessment officer or the Department from applications filed under this Section, or from any investigation conducted under the provisions of this Section, shall be confidential, except for official purposes or pursuant to official procedures for collection of any State or local tax or enforcement of any civil or criminal penalty or sanction imposed by this Act or by any statute or ordinance imposing a State or local tax. Any person who divulges any such information in any manner, except in accordance with a proper judicial order, is guilty of a Class A misdemeanor.
    Nothing contained in this Section shall prevent the Director or chief county assessment officer from publishing or making available reasonable statistics concerning the operation of the exemption contained in this Section in which the contents of claims are grouped into aggregates in such a way that information contained in any individual claim shall not be disclosed.
    Notwithstanding any other provision of law, for taxable year 2017 and thereafter, in counties of 3,000,000 or more inhabitants, the amount of the exemption shall be the greater of (i) the amount of the exemption otherwise calculated under this Section or (ii) $2,000.
    (d) Each Chief County Assessment Officer shall annually publish a notice of availability of the exemption provided under this Section. The notice shall be published at least 60 days but no more than 75 days prior to the date on which the application must be submitted to the Chief County Assessment Officer of the county in which the property is located. The notice shall appear in a newspaper of general circulation in the county.
    Notwithstanding Sections 6 and 8 of the State Mandates Act, no reimbursement by the State is required for the implementation of any mandate created by this Section.

This homestead exemption shall also apply to a leasehold interest in a parcel of property improved with a permanent structure that is a single family residence that is occupied as a residence by a person who (i) is 65 years of age or older during the taxable year, (ii) has a household income that does not exceed the maximum income limitation, (iii) has a legal or equitable ownership interest in the property as lessee, and (iv) is liable for the payment of real property taxes on that property.
    In counties of 3,000,000 or more inhabitants, the amount of the exemption for all taxable years is the equalized assessed value of the residence in the taxable year for which application is made minus the base amount. In all other counties, the amount of the exemption is as follows: (i) through taxable year 2005 and for taxable year 2007 and thereafter, the amount of this exemption shall be the equalized assessed value of the residence in the taxable year for which application is made minus the base amount; and (ii) for taxable year 2006, the amount of the exemption is as follows:
        (1) For an applicant who has a household income of
    
$45,000 or less, the amount of the exemption is the equalized assessed value of the residence in the taxable year for which application is made minus the base amount.
        (2) For an applicant who has a household income
    
exceeding $45,000 but not exceeding $46,250, the amount of the exemption is (i) the equalized assessed value of the residence in the taxable year for which application is made minus the base amount (ii) multiplied by 0.8.
        (3) For an applicant who has a household income
    
exceeding $46,250 but not exceeding $47,500, the amount of the exemption is (i) the equalized assessed value of the residence in the taxable year for which application is made minus the base amount (ii) multiplied by 0.6.
        (4) For an applicant who has a household income
    
exceeding $47,500 but not exceeding $48,750, the amount of the exemption is (i) the equalized assessed value of the residence in the taxable year for which application is made minus the base amount (ii) multiplied by 0.4.
        (5) For an applicant who has a household income
    
exceeding $48,750 but not exceeding $50,000, the amount of the exemption is (i) the equalized assessed value of the residence in the taxable year for which application is made minus the base amount (ii) multiplied by 0.2.
    When the applicant is a surviving spouse of an applicant for a prior year for the same residence for which an exemption under this Section has been granted, the base year and base amount for that residence are the same as for the applicant for the prior year.
    Each year at the time the assessment books are certified to the County Clerk, the Board of Review or Board of Appeals shall give to the County Clerk a list of the assessed values of improvements on each parcel qualifying for this exemption that were added after the base year for this parcel and that increased the assessed value of the property.
    In the case of land improved with an apartment building owned and operated as a cooperative or a building that is a life care facility that qualifies as a cooperative, the maximum reduction from the equalized assessed value of the property is limited to the sum of the reductions calculated for each unit occupied as a residence by a person or persons (i) 65 years of age or older, (ii) with a household income that does not exceed the maximum income limitation, (iii) who is liable, by contract with the owner or owners of record, for paying real property taxes on the property, and (iv) who is an owner of record of a legal or equitable interest in the cooperative apartment building, other than a leasehold interest. In the instance of a cooperative where a homestead exemption has been granted under this Section, the cooperative association or its management firm shall credit the savings resulting from that exemption only to the apportioned tax liability of the owner who qualified for the exemption. Any person who willfully refuses to credit that savings to an owner who qualifies for the exemption is guilty of a Class B misdemeanor.
    When a homestead exemption has been granted under this Section and an applicant then becomes a resident of a facility licensed under the Assisted Living and Shared Housing Act, the Nursing Home Care Act, the Specialized Mental Health Rehabilitation Act of 2013, the ID/DD Community Care Act, or the MC/DD Act, the exemption shall be granted in subsequent years so long as the residence (i) continues to be occupied by the qualified applicant's spouse or (ii) if remaining unoccupied, is still owned by the qualified applicant for the homestead exemption.
    Beginning January 1, 1997, when an individual dies who would have qualified for an exemption under this Section, and the surviving spouse does not independently qualify for this exemption because of age, the exemption under this Section shall be granted to the surviving spouse for the taxable year preceding and the taxable year of the death, provided that, except for age, the surviving spouse meets all other qualifications for the granting of this exemption for those years.
    When married persons maintain separate residences, the exemption provided for in this Section may be claimed by only one of such persons and for only one residence.
    For taxable year 1994 only, in counties having less than 3,000,000 inhabitants, to receive the exemption, a person shall submit an application by February 15, 1995 to the Chief County Assessment Officer of the county in which the property is located. In counties having 3,000,000 or more inhabitants, for taxable year 1994 and all subsequent taxable years, to receive the exemption, a person may submit an application to the Chief County Assessment Officer of the county in which the property is located during such period as may be specified by the Chief County Assessment Officer. The Chief County Assessment Officer in counties of 3,000,000 or more inhabitants shall annually give notice of the application period by mail or by publication. In counties having less than 3,000,000 inhabitants, beginning with taxable year 1995 and thereafter, to receive the exemption, a person shall submit an application by July 1 of each taxable year to the Chief County Assessment Officer of the county in which the property is located. A county may, by ordinance, establish a date for submission of applications that is different than July 1. The applicant shall submit with the application an affidavit of the applicant's total household income, age, marital status (and if married the name and address of the applicant's spouse, if known), and principal dwelling place of members of the household on January 1 of the taxable year. The Department shall establish, by rule, a method for verifying the accuracy of affidavits filed by applicants under this Section, and the Chief County Assessment Officer may conduct audits of any taxpayer claiming an exemption under this Section to verify that the taxpayer is eligible to receive the exemption. Each application shall contain or be verified by a written declaration that it is made under the penalties of perjury. A taxpayer's signing a fraudulent application under this Act is perjury, as defined in Section 32-2 of the Criminal Code of 2012. The applications shall be clearly marked as applications for the Senior Citizens Assessment Freeze Homestead Exemption and must contain a notice that any taxpayer who receives the exemption is subject to an audit by the Chief County Assessment Officer.
    Notwithstanding any other provision to the contrary, in counties having fewer than 3,000,000 inhabitants, if an applicant fails to file the application required by this Section in a timely manner and this failure to file is due to a mental or physical condition sufficiently severe so as to render the applicant incapable of filing the application in a timely manner, the Chief County Assessment Officer may extend the filing deadline for a period of 30 days after the applicant regains the capability to file the application, but in no case may the filing deadline be extended beyond 3 months of the original filing deadline. In order to receive the extension provided in this paragraph, the applicant shall provide the Chief County Assessment Officer with a signed statement from the applicant's physician, advanced practice registered nurse, or physician assistant stating the nature and extent of the condition, that, in the physician's, advanced practice registered nurse's, or physician assistant's opinion, the condition was so severe that it rendered the applicant incapable of filing the application in a timely manner, and the date on which the applicant regained the capability to file the application.
    Beginning January 1, 1998, notwithstanding any other provision to the contrary, in counties having fewer than 3,000,000 inhabitants, if an applicant fails to file the application required by this Section in a timely manner and this failure to file is due to a mental or physical condition sufficiently severe so as to render the applicant incapable of filing the application in a timely manner, the Chief County Assessment Officer may extend the filing deadline for a period of 3 months. In order to receive the extension provided in this paragraph, the applicant shall provide the Chief County Assessment Officer with a signed statement from the applicant's physician, advanced practice registered nurse, or physician assistant stating the nature and extent of the condition, and that, in the physician's, advanced practice registered nurse's, or physician assistant's opinion, the condition was so severe that it rendered the applicant incapable of filing the application in a timely manner.
    In counties having less than 3,000,000 inhabitants, if an applicant was denied an exemption in taxable year 1994 and the denial occurred due to an error on the part of an assessment official, or his or her agent or employee, then beginning in taxable year 1997 the applicant's base year, for purposes of determining the amount of the exemption, shall be 1993 rather than 1994. In addition, in taxable year 1997, the applicant's exemption shall also include an amount equal to (i) the amount of any exemption denied to the applicant in taxable year 1995 as a result of using 1994, rather than 1993, as the base year, (ii) the amount of any exemption denied to the applicant in taxable year 1996 as a result of using 1994, rather than 1993, as the base year, and (iii) the amount of the exemption erroneously denied for taxable year 1994.
    For purposes of this Section, a person who will be 65 years of age during the current taxable year shall be eligible to apply for the homestead exemption during that taxable year. Application shall be made during the application period in effect for the county of his or her residence.
    The Chief County Assessment Officer may determine the eligibility of a life care facility that qualifies as a cooperative to receive the benefits provided by this Section by use of an affidavit, application, visual inspection, questionnaire, or other reasonable method in order to insure that the tax savings resulting from the exemption are credited by the management firm to the apportioned tax liability of each qualifying resident. The Chief County Assessment Officer may request reasonable proof that the management firm has so credited that exemption.
    Except as provided in this Section, all information received by the chief county assessment officer or the Department from applications filed under this Section, or from any investigation conducted under the provisions of this Section, shall be confidential, except for official purposes or pursuant to official procedures for collection of any State or local tax or enforcement of any civil or criminal penalty or sanction imposed by this Act or by any statute or ordinance imposing a State or local tax. Any person who divulges any such information in any manner, except in accordance with a proper judicial order, is guilty of a Class A misdemeanor.
    Nothing contained in this Section shall prevent the Director or chief county assessment officer from publishing or making available reasonable statistics concerning the operation of the exemption contained in this Section in which the contents of claims are grouped into aggregates in such a way that information contained in any individual claim shall not be disclosed.
    (d) Each Chief County Assessment Officer shall annually publish a notice of availability of the exemption provided under this Section. The notice shall be published at least 60 days but no more than 75 days prior to the date on which the application must be submitted to the Chief County Assessment Officer of the county in which the property is located. The notice shall appear in a newspaper of general circulation in the county.
    Notwithstanding Sections 6 and 8 of the State Mandates Act, no reimbursement by the State is required for the implementation of any mandate created by this Section.

    Sec. 15-173. Natural Disaster Homestead Exemption.
    (a) This Section may be cited as the Natural Disaster Homestead Exemption.
    (b) As used in this Section:
    "Base amount" means the base year equalized assessed value of the residence.
    "Base year" means the taxable year prior to the taxable year in which the natural disaster occurred.
    "Chief county assessment officer" means the County Assessor or Supervisor of Assessments of the county in which the property is located.
    "Equalized assessed value" means the assessed value as equalized by the Illinois Department of Revenue.
    "Homestead property" has the meaning ascribed to that term in Section 15-175 of this Code.
    "Natural disaster" means an occurrence of widespread or severe damage or loss of property resulting from any catastrophic cause including but not limited to fire, flood, earthquake, wind, storm, or extended period of severe inclement weather. In the case of a residential structure affected by flooding, the structure shall not be eligible for this homestead improvement exemption unless it is located within a local jurisdiction which is participating in the National Flood Insurance Program. A proclamation of disaster by the President of the United States or Governor of the State of Illinois is not a prerequisite to the classification of an occurrence as a natural disaster under this Section.
    (c) A homestead exemption shall be granted by the chief county assessment officer for homestead properties containing a residential structure that has been rebuilt following a natural disaster occurring in taxable year 2012 or any taxable year thereafter. The amount of the exemption is the equalized assessed value of the residence in the first taxable year for which the taxpayer applies for an exemption under this Section minus the base amount. To be eligible for an exemption under this Section: (i) the residential structure must be rebuilt within 2 years after the date of the natural disaster; and (ii) the square footage of the rebuilt residential structure may not be more than 110% of the square footage of the original residential structure as it existed immediately prior to the natural disaster. The taxpayer's initial application for an exemption under this Section must be made no later than the first taxable year after the residential structure is rebuilt. The exemption shall continue at the same annual amount until the taxable year in which the property is sold or transferred.
    (d) To receive the exemption, the taxpayer shall submit an application to the chief county assessment officer of the county in which the property is located by July 1 of each taxable year. A county may, by resolution, establish a date for submission of applications that is different than July 1. The chief county assessment officer may require additional documentation to be provided by the applicant. The applications shall be clearly marked as applications for the Natural Disaster Homestead Exemption.
    (e) Property is not eligible for an exemption under this Section and Section 15-180 for the same natural disaster or catastrophic event. The property may, however, remain eligible for an additional exemption under Section 15-180 for any separate event occurring after the property qualified for an exemption under this Section.
    (f) The exemption under this Section carries over to the benefit of the surviving spouse as long as the spouse holds the legal or beneficial title to the homestead and permanently resides thereon.
    (g) Notwithstanding Sections 6 and 8 of the State Mandates Act, no reimbursement by the State is required for the implementation of any mandate created by this Section.

        (4) If there is a transfer of ownership during the
    
period of the assessment freeze, then the benefit conferred by this Section shall not apply on or after the date of that transfer unless (i) the property is conveyed by an owner who does not occupy the improvements as a primary residence to an owner who will occupy the improvements as a primary residence and (ii) all requirements of this Section continue to be met.
    (f) If the taxpayer does not occupy or intend to occupy the residential dwelling as his or her principal residence within a reasonable time, as determined by the chief county assessment officer, the taxpayer must:

    (35 ILCS 200/15-175)
    Sec. 15-175. General homestead exemption.
    (a) Except as provided in Sections 15-176 and 15-177, homestead property is entitled to an annual homestead exemption limited, except as described here with relation to cooperatives, to a reduction in the equalized assessed value of homestead property equal to the increase in equalized assessed value for the current assessment year above the equalized assessed value of the property for 1977, up to the maximum reduction set forth below. If however, the 1977 equalized assessed value upon which taxes were paid is subsequently determined by local assessing officials, the Property Tax Appeal Board, or a court to have been excessive, the equalized assessed value which should have been placed on the property for 1977 shall be used to determine the amount of the exemption.
    (b) Except as provided in Section 15-176, the maximum reduction before taxable year 2004 shall be $4,500 in counties with 3,000,000 or more inhabitants and $3,500 in all other counties. Except as provided in Sections 15-176 and 15-177, for taxable years 2004 through 2007, the maximum reduction shall be $5,000, for taxable year 2008, the maximum reduction is $5,500, and, for taxable years 2009 through 2011, the maximum reduction is $6,000 in all counties. For taxable years 2012 through 2016, the maximum reduction is $7,000 in counties with 3,000,000 or more inhabitants and $6,000 in all other counties. For taxable years 2017 and thereafter, the maximum reduction is $10,000 in counties with 3,000,000 or more inhabitants and $6,000 in all other counties. If a county has elected to subject itself to the provisions of Section 15-176 as provided in subsection (k) of that Section, then, for the first taxable year only after the provisions of Section 15-176 no longer apply, for owners who, for the taxable year, have not been granted a senior citizens assessment freeze homestead exemption under Section 15-172 or a long-time occupant homestead exemption under Section 15-177, there shall be an additional exemption of $5,000 for owners with a household income of $30,000 or less.
    (c) In counties with fewer than 3,000,000 inhabitants, if, based on the most recent assessment, the equalized assessed value of the homestead property for the current assessment year is greater than the equalized assessed value of the property for 1977, the owner of the property shall automatically receive the exemption granted under this Section in an amount equal to the increase over the 1977 assessment up to the maximum reduction set forth in this Section.
    (d) If in any assessment year beginning with the 2000 assessment year, homestead property has a pro-rata valuation under Section 9-180 resulting in an increase in the assessed valuation, a reduction in equalized assessed valuation equal to the increase in equalized assessed value of the property for the year of the pro-rata valuation above the equalized assessed value of the property for 1977 shall be applied to the property on a proportionate basis for the period the property qualified as homestead property during the assessment year. The maximum proportionate homestead exemption shall not exceed the maximum homestead exemption allowed in the county under this Section divided by 365 and multiplied by the number of days the property qualified as homestead property.
    (d-1) In counties with 3,000,000 or more inhabitants, where the chief county assessment officer provides a notice of discovery, if a property is not occupied by its owner as a principal residence as of January 1 of the current tax year, then the property owner shall notify the chief county assessment officer of that fact on a form prescribed by the chief county assessment officer. That notice must be received by the chief county assessment officer on or before March 1 of the collection year. If mailed, the form shall be sent by certified mail, return receipt requested. If the form is provided in person, the chief county assessment officer shall provide a date stamped copy of the notice. Failure to provide timely notice pursuant to this subsection (d-1) shall result in the exemption being treated as an erroneous exemption. Upon timely receipt of the notice for the current tax year, no exemption shall be applied to the property for the current tax year. If the exemption is not removed upon timely receipt of the notice by the chief assessment officer, then the error is considered granted as a result of a clerical error or omission on the part of the chief county assessment officer as described in subsection (h) of Section 9-275, and the property owner shall not be liable for the payment of interest and penalties due to the erroneous exemption for the current tax year for which the notice was filed after the date that notice was timely received pursuant to this subsection. Notice provided under this subsection shall not constitute a defense or amnesty for prior year erroneous exemptions.
    For the purposes of this subsection (d-1):
    "Collection year" means the year in which the first and second installment of the current tax year is billed.
    "Current tax year" means the year prior to the collection year.
    (e) The chief county assessment officer may, when considering whether to grant a leasehold exemption under this Section, require the following conditions to be met:
        (1) that a notarized application for the exemption,
    
signed by both the owner and the lessee of the property, must be submitted each year during the application period in effect for the county in which the property is located;
        (2) that a copy of the lease must be filed with the
    
chief county assessment officer by the owner of the property at the time the notarized application is submitted;
        (3) that the lease must expressly state that the
    
lessee is liable for the payment of property taxes; and
        (4) that the lease must include the following
    
language in substantially the following form:
            "Lessee shall be liable for the payment of real
        
estate taxes with respect to the residence in accordance with the terms and conditions of Section 15-175 of the Property Tax Code (35 ILCS 200/15-175). The permanent real estate index number for the premises is (insert number), and, according to the most recent property tax bill, the current amount of real estate taxes associated with the premises is (insert amount) per year. The parties agree that the monthly rent set forth above shall be increased or decreased pro rata (effective January 1 of each calendar year) to reflect any increase or decrease in real estate taxes. Lessee shall be deemed to be satisfying Lessee's liability for the above mentioned real estate taxes with the monthly rent payments as set forth above (or increased or decreased as set forth herein).".
    In addition, if there is a change in lessee, or if the lessee vacates the property, then the chief county assessment officer may require the owner of the property to notify the chief county assessment officer of that change.
    This subsection (e) does not apply to leasehold interests in property owned by a municipality.
    (f) "Homestead property" under this Section includes residential property that is occupied by its owner or owners as his or their principal dwelling place, or that is a leasehold interest on which a single family residence is situated, which is occupied as a residence by a person who has an ownership interest therein, legal or equitable or as a lessee, and on which the person is liable for the payment of property taxes. For land improved with an apartment building owned and operated as a cooperative or a building which is a life care facility as defined in Section 15-170 and considered to be a cooperative under Section 15-170, the maximum reduction from the equalized assessed value shall be limited to the increase in the value above the equalized assessed value of the property for 1977, up to the maximum reduction set forth above, multiplied by the number of apartments or units occupied by a person or persons who is liable, by contract with the owner or owners of record, for paying property taxes on the property and is an owner of record of a legal or equitable interest in the cooperative apartment building, other than a leasehold interest. For purposes of this Section, the term "life care facility" has the meaning stated in Section 15-170.
    "Household", as used in this Section, means the owner, the spouse of the owner, and all persons using the residence of the owner as their principal place of residence.
    "Household income", as used in this Section, means the combined income of the members of a household for the calendar year preceding the taxable year.
    "Income", as used in this Section, has the same meaning as provided in Section 3.07 of the Senior Citizens and Persons with Disabilities Property Tax Relief Act, except that "income" does not include veteran's benefits.
    (g) In a cooperative where a homestead exemption has been granted, the cooperative association or its management firm shall credit the savings resulting from that exemption only to the apportioned tax liability of the owner who qualified for the exemption. Any person who willfully refuses to so credit the savings shall be guilty of a Class B misdemeanor.
    (h) Where married persons maintain and reside in separate residences qualifying as homestead property, each residence shall receive 50% of the total reduction in equalized assessed valuation provided by this Section.
    (i) In all counties, the assessor or chief county assessment officer may determine the eligibility of residential property to receive the homestead exemption and the amount of the exemption by application, visual inspection, questionnaire or other reasonable methods. The determination shall be made in accordance with guidelines established by the Department, provided that the taxpayer applying for an additional general exemption under this Section shall submit to the chief county assessment officer an application with an affidavit of the applicant's total household income, age, marital status (and, if married, the name and address of the applicant's spouse, if known), and principal dwelling place of members of the household on January 1 of the taxable year. The Department shall issue guidelines establishing a method for verifying the accuracy of the affidavits filed by applicants under this paragraph. The applications shall be clearly marked as applications for the Additional General Homestead Exemption.
    (i-5) This subsection (i-5) applies to counties with 3,000,000 or more inhabitants. In the event of a sale of homestead property, the homestead exemption shall remain in effect for the remainder of the assessment year of the sale. Upon receipt of a transfer declaration transmitted by the recorder pursuant to Section 31-30 of the Real Estate Transfer Tax Law for property receiving an exemption under this Section, the assessor shall mail a notice and forms to the new owner of the property providing information pertaining to the rules and applicable filing periods for applying or reapplying for homestead exemptions under this Code for which the property may be eligible. If the new owner fails to apply or reapply for a homestead exemption during the applicable filing period or the property no longer qualifies for an existing homestead exemption, the assessor shall cancel such exemption for any ensuing assessment year.
    (j) In counties with fewer than 3,000,000 inhabitants, in the event of a sale of homestead property the homestead exemption shall remain in effect for the remainder of the assessment year of the sale. The assessor or chief county assessment officer may require the new owner of the property to apply for the homestead exemption for the following assessment year.
    (k) Notwithstanding Sections 6 and 8 of the State Mandates Act, no reimbursement by the State is required for the implementation of any mandate created by this Section.

Except as provided in subdivision (b)(3)(B), if the property did not have a residential equalized assessed value for the base year, then "base homestead value" means the base homestead value established by the assessor under subsection (c).
            (A-5) On or before September 1, 2007, in Cook
        
County, the base homestead value, as set forth under subdivision (b)(3)(A) and except as provided under subdivision (b) (3) (B), must be recalculated as the equalized assessed value of the property for the base year, prior to exemptions, minus:

Residential units in an apartment building owned and operated as a cooperative, or as a life care facility, which are occupied by persons who hold a legal or equitable interest in the cooperative apartment building or life care facility as owners or lessees, and who are liable by contract for the payment of property taxes, shall be included within this definition of homestead property.
            (B) A homestead includes the dwelling place,
        
appurtenant structures, and so much of the surrounding land constituting the parcel on which the dwelling place is situated as is used for residential purposes. If the assessor has established a specific legal description for a portion of property constituting the homestead, then the homestead shall be limited to the property within that description.
        (7) "Life care facility" means a facility as defined
    
in Section 2 of the Life Care Facilities Act.
    (c) If the property did not have a residential equalized assessed value for the base year as provided in subdivision (b)(3)(A) of this Section, then the assessor shall first determine an initial value for the property by comparison with assessed values for the base year of other properties having physical and economic characteristics similar to those of the subject property, so that the initial value is uniform in relation to assessed values of those other properties for the base year. The product of the initial value multiplied by the equalized factor for the base year for homestead properties in that county, less: (i) $4,500 in Cook County or $3,500 in all other counties in tax year 2003; (ii) $5,000 in all counties in tax years 2004 and 2005; and (iii) the lesser of the amount of the general homestead exemption under Section 15-175 or an amount equal to the increase in the equalized assessed value for the current tax year above the equalized assessed value for 1977 in tax year 2006 and thereafter, is the base homestead value.
    For any tax year for which the assessor determines or adjusts an initial value and hence a base homestead value under this subsection (c), the initial value shall be subject to review by the same procedures applicable to assessed values established under this Code for that tax year.
    (d) The base homestead value shall remain constant, except that the assessor may revise it under the following circumstances:
        (1) If the equalized assessed value of a homestead
    
property for the current tax year is less than the previous base homestead value for that property, then the current equalized assessed value (provided it is not based on a reduced assessed value resulting from a temporary irregularity in the property) shall become the base homestead value in subsequent tax years.
        (2) For any year in which new buildings, structures,
    
or other improvements are constructed on the homestead property that would increase its assessed value, the assessor shall adjust the base homestead value as provided in subsection (c) of this Section with due regard to the value added by the new improvements.
        (3) If the property is sold or ownership is otherwise
    
transferred, the base homestead value of the property shall be adjusted as provided in subdivision (b)(3)(B). This item (3) does not apply to sales or transfers between spouses or between a parent and a child.
        (4) the recalculation required in Cook County under
    
subdivision (b)(3)(A-5).
    (e) The amount of the exemption under this Section is the equalized assessed value of the homestead property for the current tax year, minus the adjusted homestead value, with the following exceptions:
        (1) In Cook County, the exemption under this Section
    
shall not exceed $20,000 for any taxable year through tax year:
            (i) 2005, if the general assessment year for the
        
property is 2003;
            (ii) 2006, if the general assessment year for the
        
property is 2004; or
            (iii) 2007, if the general assessment year for
        
the property is 2005.
        (1.1) Thereafter, in Cook County, and in all other
    
counties, the exemption is as follows:
            (i) if the general assessment year for the
        
property is 2006, then the exemption may not exceed: $33,000 for taxable year 2006; $26,000 for taxable year 2007; $20,000 for taxable years 2008 and 2009; $16,000 for taxable year 2010; and $12,000 for taxable year 2011;
            (ii) if the general assessment year for the
        
property is 2007, then the exemption may not exceed: $33,000 for taxable year 2007; $26,000 for taxable year 2008; $20,000 for taxable years 2009 and 2010; $16,000 for taxable year 2011; and $12,000 for taxable year 2012; and
            (iii) if the general assessment year for the
        
property is 2008, then the exemption may not exceed: $33,000 for taxable year 2008; $26,000 for taxable year 2009; $20,000 for taxable years 2010 and 2011; $16,000 for taxable year 2012; and $12,000 for taxable year 2013.
    (1.5) In Cook County, for the 2006 taxable year only, the maximum amount of the exemption set forth under subsection (e)(1.1)(i) of this Section may be increased: (i) by $7,000 if the equalized assessed value of the property in that taxable year exceeds the equalized assessed value of that property in 2002 by 100% or more; or (ii) by $2,000 if the equalized assessed value of the property in that taxable year exceeds the equalized assessed value of that property in 2002 by more than 80% but less than 100%.
        (2) In the case of homestead property that also
    
qualifies for the exemption under Section 15-172, the property is entitled to the exemption under this Section, limited to the amount of (i) $4,500 in Cook County or $3,500 in all other counties in tax year 2003, (ii) $5,000 in all counties in tax years 2004 and 2005, or (iii) the lesser of the amount of the general homestead exemption under Section 15-175 or an amount equal to the increase in the equalized assessed value for the current tax year above the equalized assessed value for 1977 in tax year 2006 and thereafter.
    (f) In the case of an apartment building owned and operated as a cooperative, or as a life care facility, that contains residential units that qualify as homestead property under this Section, the maximum cumulative exemption amount attributed to the entire building or facility shall not exceed the sum of the exemptions calculated for each qualified residential unit. The cooperative association, management firm, or other person or entity that manages or controls the cooperative apartment building or life care facility shall credit the exemption attributable to each residential unit only to the apportioned tax liability of the owner or other person responsible for payment of taxes as to that unit. Any person who willfully refuses to so credit the exemption is guilty of a Class B misdemeanor.
    (g) When married persons maintain separate residences, the exemption provided under this Section shall be claimed by only one such person and for only one residence.
    (h) In the event of a sale or other transfer in ownership of the homestead property, the exemption under this Section shall remain in effect for the remainder of the tax year and be calculated using the same base homestead value in which the sale or transfer occurs, but (other than for sales or transfers between spouses or between a parent and a child) shall be calculated for any subsequent tax year using the new base homestead value as provided in subdivision (b)(3)(B). The assessor may require the new owner of the property to apply for the exemption in the following year.
    (i) The assessor may determine whether property qualifies as a homestead under this Section by application, visual inspection, questionnaire, or other reasonable methods. Each year, at the time the assessment books are certified to the county clerk by the board of review, the assessor shall furnish to the county clerk a list of the properties qualified for the homestead exemption under this Section. The list shall note the base homestead value of each property to be used in the calculation of the exemption for the current tax year.
    (j) In counties with 3,000,000 or more inhabitants, the provisions of this Section apply as follows:
        (1) If the general assessment year for the property
    
is 2003, this Section applies for assessment years 2003 through 2011. Thereafter, the provisions of Section 15-175 apply.
        (2) If the general assessment year for the property
    
is 2004, this Section applies for assessment years 2004 through 2012. Thereafter, the provisions of Section 15-175 apply.
        (3) If the general assessment year for the property
    
is 2005, this Section applies for assessment years 2005 through 2013. Thereafter, the provisions of Section 15-175 apply.
    In counties with less than 3,000,000 inhabitants, this Section applies for assessment years (i) 2009, 2010, 2011, and 2012 if tax year 2008 is the designated base year or (ii) 2010, 2011, 2012, and 2013 if tax year 2009 is the designated base year. Thereafter, the provisions of Section 15-175 apply.
    (k) To be subject to the provisions of this Section in lieu of Section 15-175, a county must adopt an ordinance to subject itself to the provisions of this Section within 6 months after August 2, 2010 (the effective date of Public Act 96-1418). In a county other than Cook County, the ordinance must designate either tax year 2008 or tax year 2009 as the base year.
    (l) Notwithstanding Sections 6 and 8 of the State Mandates Act, no reimbursement by the State is required for the implementation of any mandate created by this Section.

        (2) if the property had an adjusted homestead value
    
under Section 15-176 for the base year, then an amount equal to the adjusted homestead value of the property under Section 15-176 for the base year.

property for the current tax year is less than the previous base homestead value for that property, then the current equalized assessed value (provided it is not based on a reduced assessed value resulting from a temporary irregularity in the property) becomes the base homestead value in subsequent tax years.
        (2) For any year in which new buildings, structures,
    
or other improvements are constructed on the homestead property that would increase its assessed value, the assessor shall adjust the base homestead value with due regard to the value added by the new improvements.
    (d) The amount of the exemption under this Section is the greater of: (i) the equalized assessed value of the homestead property for the current tax year minus the adjusted homestead value; or (ii) the general homestead deduction.
    (e) In the case of an apartment building owned and operated as a cooperative, or as a life care facility, that contains residential units that qualify as homestead property of a qualified taxpayer under this Section, the maximum cumulative exemption amount attributed to the entire building or facility shall not exceed the sum of the exemptions calculated for each unit that is a qualified homestead property. The cooperative association, management firm, or other person or entity that manages or controls the cooperative apartment building or life care facility shall credit the exemption attributable to each residential unit only to the apportioned tax liability of the qualified taxpayer as to that unit. Any person who willfully refuses to so credit the exemption is guilty of a Class B misdemeanor.
    (f) When married persons maintain separate residences, the exemption provided under this Section may be claimed by only one such person and for only one residence. No person who receives an exemption under Section 15-172 of this Code may receive an exemption under this Section. No person who receives an exemption under this Section may receive an exemption under Section 15-175 or 15-176 of this Code.
    (g) In the event of a sale or other transfer in ownership of the homestead property between spouses or between a parent and a child, the exemption under this Section remains in effect if the new owner has a household income of $100,000 or less.
    (h) In the event of a sale or other transfer in ownership of the homestead property other than subsection (g) of this Section, the exemption under this Section shall remain in effect for the remainder of the tax year and be calculated using the same base homestead value in which the sale or transfer occurs.
    (i) To receive the exemption, a person must submit an application to the county assessor during the period specified by the county assessor.
    The county assessor shall annually give notice of the application period by mail or by publication.
    The taxpayer must submit, with the application, an affidavit of the taxpayer's total household income, marital status (and if married the name and address of the applicant's spouse, if known), and principal dwelling place of members of the household on January 1 of the taxable year. The Department shall establish, by rule, a method for verifying the accuracy of affidavits filed by applicants under this Section, and the Chief County Assessment Officer may conduct audits of any taxpayer claiming an exemption under this Section to verify that the taxpayer is eligible to receive the exemption. Each application shall contain or be verified by a written declaration that it is made under the penalties of perjury. A taxpayer's signing a fraudulent application under this Act is perjury, as defined in Section 32-2 of the Criminal Code of 2012. The applications shall be clearly marked as applications for the Long-time Occupant Homestead Exemption and must contain a notice that any taxpayer who receives the exemption is subject to an audit by the Chief County Assessment Officer.
    (j) Notwithstanding Sections 6 and 8 of the State Mandates Act, no reimbursement by the State is required for the implementation of any mandate created by this Section.

    (35 ILCS 200/15-180)
    Sec. 15-180. Homestead improvements. Homestead properties that have been improved and residential structures on homestead property that have been rebuilt following a catastrophic event are entitled to a homestead improvement exemption, limited to $30,000 per year through December 31, 1997, $45,000 beginning January 1, 1998 and through December 31, 2003, and $75,000 per year for that homestead property beginning January 1, 2004 and thereafter, in fair cash value, when that property is owned and used exclusively for a residential purpose and upon demonstration that a proposed increase in assessed value is attributable solely to a new improvement of an existing structure or the rebuilding of a residential structure following a catastrophic event. To be eligible for an exemption under this Section after a catastrophic event, the residential structure must be rebuilt within 2 years after the catastrophic event. The exemption for rebuilt structures under this Section applies to the increase in value of the rebuilt structure over the value of the structure before the catastrophic event. The amount of the exemption shall be limited to the fair cash value added by the new improvement or rebuilding and shall continue for 4 years from the date the improvement or rebuilding is completed and occupied, or until the next following general assessment of that property, whichever is later.
    A proclamation of disaster by the President of the United States or Governor of the State of Illinois is not a prerequisite to the classification of an occurrence as a catastrophic event under this Section. A "catastrophic event" may include an occurrence of widespread or severe damage or loss of property resulting from any catastrophic cause including but not limited to fire, including arson (provided the fire was not caused by the willful action of an owner or resident of the property), flood, earthquake, wind, storm, explosion, or extended periods of severe inclement weather. In the case of a residential structure affected by flooding, the structure shall not be eligible for this homestead improvement exemption unless it is located within a local jurisdiction which is participating in the National Flood Insurance Program.
    In counties of less than 3,000,000 inhabitants, in addition to the notice requirement under Section 12-30, a supervisor of assessments, county assessor, or township or multi-township assessor responsible for adding an assessable improvement to a residential property's assessment shall either notify a taxpayer whose assessment has been changed since the last preceding assessment that he or she may be eligible for the exemption provided under this Section or shall grant the exemption automatically.
    Beginning January 1, 1999, in counties of 3,000,000 or more inhabitants, an application for a homestead improvement exemption for a residential structure that has been rebuilt following a catastrophic event must be submitted to the Chief County Assessment Officer with a valuation complaint and a copy of the building permit to rebuild the structure. The Chief County Assessment Officer may require additional documentation which must be provided by the applicant.
    Notwithstanding Sections 6 and 8 of the State Mandates Act, no reimbursement by the State is required for the implementation of any mandate created by this Section.

Property shall no longer be exempt under this subsection as of the date when the right of the municipality or unit of local government to use, control, and possess the property or to require the performance of services is terminated and the municipality or unit of local government no longer has any option to purchase or otherwise reacquire the interest in the property which was transferred by the municipality or unit of local government.
