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.

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, "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

    (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.
(Source: P.A. 96-1288, eff. 7-26-10; 96-1418, eff. 8-2-10; 97-333, eff. 8-12-11.)

35 ILCS 200/15-168

    (35 ILCS 200/15-168)
    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 registered 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.

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.
    (b) 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.
    (c) 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.
    (d) 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.
    (e) 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.
    (f) 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.
    (g) 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.
    (h) 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.
    (i) In counties with 3,000,000 or more inhabitants, for taxable years 2010 through 2019, and beginning again in taxable year 2025, each taxpayer who has been granted an exemption under this Section must reapply on an annual basis.
    If a reapplication is required, then the chief county assessment officer shall mail the application to the taxpayer at least 60 days prior to the last day of the application period for the county.
    For taxable years 2020 through 2024, in counties with 3,000,000 or more inhabitants, a taxpayer who has been granted an exemption under this Section need not reapply. However, if the property ceases to be qualified for the exemption under this Section in any year for which a reapplication is not required under this Section, then the owner of record of the property shall notify the chief county assessment officer that the property is no longer qualified. In addition, for taxable years 2020 through 2024, the chief county assessment officer of a county with 3,000,000 or more inhabitants shall enter into an intergovernmental agreement with the county clerk of that county and the Department of Public Health, as well as any other appropriate governmental agency, to obtain information that documents the death of a taxpayer who has been granted an exemption under this Section. Notwithstanding any other provision of law, the county clerk and the Department of Public Health shall provide that information to the chief county assessment officer. The Department of Public Health shall supply this information no less frequently than every calendar quarter. Information concerning the death of a taxpayer may be shared with the county treasurer. The chief county assessment officer shall also enter into a data exchange agreement with the Social Security Administration or its agent to obtain access to the information regarding deaths in possession of the Social Security Administration. The chief county assessment officer shall, subject to the notice requirements under subsection (m) of Section 9-275, terminate the exemption under this Section if the information obtained indicates that the property is no longer qualified for the exemption. In counties with 3,000,000 or more inhabitants, the assessor and the county recorder of deeds shall establish policies and practices for the regular exchange of information for the purpose of alerting the assessor whenever the transfer of ownership of any property receiving an exemption under this Section has occurred. When such a transfer occurs, the assessor shall mail a notice to the new owner of the property (i) informing the new owner that the exemption will remain in place through the year of the transfer, after which it will be canceled, and (ii) providing information pertaining to the rules for reapplying for the exemption if the owner qualifies. In counties with 3,000,000 or more inhabitants, the chief county assessment official shall conduct audits of all exemptions granted under this Section no later than December 31, 2022 and no later than December 31, 2024. The audit shall be designed to ascertain whether any senior homestead exemptions have been granted erroneously. If it is determined that a senior homestead exemption has been erroneously applied to a property, the chief county assessment officer shall make use of the appropriate provisions of Section 9-275 in relation to the property that received the erroneous homestead exemption.
    (j) 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.
    (l) 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.
    (m) 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.

    "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

        (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.
    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.

    "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.

35 ILCS 200/15-175

    (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 or life care facilities, 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, 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 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 a person or persons, irrespective of any legal, equitable, or leasehold interest in the facility, who are liable, under a life care contract with the owner or owners of record of the facility, for paying property taxes on the property. 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 or life care facility where a homestead exemption has been granted, the cooperative association or the management of the cooperative or life care 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.
    (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.
    (l) The changes made to this Section by this amendatory Act of the 100th General Assembly are effective for the 2018 tax year and thereafter.

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.

    (35 ILCS 200/15-177)
    Sec. 15-177. The long-time occupant homestead exemption.
    (a) If the county has elected, under Section 15-176, to be subject to the provisions of the alternative general homestead exemption, then, for taxable years 2007 and thereafter, regardless of whether the exemption under Section 15-176 applies, qualified homestead property is entitled to an annual homestead exemption equal to a reduction in the property's equalized assessed value calculated as provided in this Section.
    (b) As used in this Section:
    "Adjusted homestead value" means the lesser of the following values:
        (1) The property's base homestead value increased
    
by: (i) 10% for each taxable year after the base year through and including the current tax year for qualified taxpayers with a household income of more than $75,000 but not exceeding $100,000; or (ii) 7% for each taxable year after the base year through and including the current tax year for qualified taxpayers with a household income of $75,000 or less. The increase each year is an increase over the prior year; or
        (2) The property's equalized assessed value for
    
the current tax year minus the general homestead deduction.
    "Base homestead value" means:
        (1) if the property did not have an adjusted
    
homestead value under Section 15-176 for the base year, then an amount equal to the equalized assessed value of the property for the base year prior to exemptions, minus the general homestead deduction, provided that the property's assessment was not based on a reduced assessed value resulting from a temporary irregularity in the property for that year; or
        (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.
    "Base year" means the taxable year prior to the taxable year in which the taxpayer first qualifies for the exemption under this Section.
    "Current taxable year" means the taxable year for which the exemption under this Section is being applied.
    "Equalized assessed value" means the property's assessed value as equalized by the Department.
    "Homestead" or "homestead property" means residential property that as of January 1 of the tax year is occupied by a qualified taxpayer as his or her principal dwelling place, or that is a leasehold interest on which a single family residence is situated, that is occupied as a residence by a qualified taxpayer who has a legal or equitable interest therein evidenced by a written instrument, as an owner or as a lessee, and on which the person is liable for the payment of property taxes. 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, are included within this definition of homestead property. 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 is limited to the property within that description.
    "Household income" has the meaning set forth under Section 15-172 of this Code.
    "General homestead deduction" means the amount of the general homestead exemption under Section 15-175.
    "Life care facility" means a facility defined in Section 2 of the Life Care Facilities Act.
    "Qualified homestead property" means homestead property owned by a qualified taxpayer.
    "Qualified taxpayer" means any individual:
        (1) who, for at least 10 continuous years as of
    
January 1 of the taxable year, has occupied the same homestead property as a principal residence and domicile or who, for at least 5 continuous years as of January 1 of the taxable year, has occupied the same homestead property as a principal residence and domicile if that person received assistance in the acquisition of the property as part of a government or nonprofit housing program; and
        (2) who has a household income of $100,000 or less.
    (c) The base homestead value must remain constant, except that the assessor may revise it under any of 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) 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

    (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.

    (a) In counties with 3,000,000 or more inhabitants, the chief county assessment officer shall maintain records of the assessed value of each parcel of property and shall enter upon the property record card of each town or city lot or parcel of land the elements (or basis) of valuation and computations that are taken into consideration by the chief county assessment officer in ascertaining and determining the fair cash value of each town or city lot or parcel of land and of each improvement thereon, including the elements (shown by percentages or otherwise) that were taken into consideration as enhancing or detracting elements (such as depth, corner, alley, railway or other elements).

    (b) In counties with 3,000,000 or more inhabitants, the notice given by the chief county assessment officer to a taxpayer of a proposed increase in assessment shall designate the reason for the increase.

    (35 ILCS 200/16-55)
    Sec. 16-55. Complaints.
    (a) On written complaint that any property is overassessed or underassessed, the board shall review the assessment, and correct it, as appears to be just, but in no case shall the property be assessed at a higher percentage of fair cash value than other property in the assessment district prior to equalization by the board or the Department.
    (b) The board shall include compulsory sales in reviewing and correcting assessments, including, but not limited to, those compulsory sales submitted by the complainant, if the board determines that those sales reflect the same property characteristics and condition as those originally used to make the assessment. The board shall also consider whether the compulsory sale would otherwise be considered an arm's length transaction.
    (c) If a complaint is filed by an attorney on behalf of a complainant, all notices and correspondence from the board relating to the appeal shall be directed to the attorney. The board may require proof of the attorney's authority to represent the taxpayer. If the attorney fails to provide proof of authority within the compliance period granted by the board pursuant to subsection (d), the board may dismiss the complaint. The Board shall send, electronically or by mail, notice of the dismissal to the attorney and complainant.
    (d) A complaint to affect the assessment for the current year shall be filed on or before 30 calendar days after the date of publication of the assessment list under Section 12-10. Upon receipt of a written complaint that is timely filed under this Section, the board of review shall docket the complaint. If the complaint does not comply with the board of review rules adopted under Section 9-5 entitling the complainant to a hearing, the board shall send, electronically or by mail, notification acknowledging receipt of the complaint. The notification must identify which rules have not been complied with and provide the complainant with not less than 10 business days to bring the complaint into compliance with those rules. If the complainant complies with the board of review rules either upon the initial filing of a complaint or within the time as extended by the board of review for compliance, then the board of review shall send, electronically or by mail, a notice of hearing and the board shall hear the complaint and shall issue and send, electronically or by mail, a decision upon resolution. Except as otherwise provided in subsection (c), if the complainant has not complied with the rules within the time as extended by the board of review, the board shall nonetheless issue and send a decision. The board of review may adopt rules allowing any party to attend and participate in a hearing by telephone or electronically.
    (d-5) Complaints and other written correspondence sent by the United States mail shall be considered filed as of the postmark date in accordance with Section 1.25 of the Statute on Statutes. Complaints and other written correspondence sent by a delivery service other than the United States Postal System shall be considered as filed as of the date sent as indicated by the shipper's tracking label. If allowed by board of review rule, complaints and other written correspondence transmitted electronically shall be considered filed as of the date received.
    (e) The board may also, at any time before its revision of the assessments is completed in every year, increase, reduce or otherwise adjust the assessment of any property, making changes in the valuation as may be just, and shall have full power over the assessment of any person and may do anything in regard thereto that it may deem necessary to make a just assessment, but the property shall not be assessed at a higher percentage of fair cash value than the assessed valuation of other property in the assessment district prior to equalization by the board or the Department.
    (f) No assessment shall be increased until the person to be affected has been notified and given an opportunity to be heard, except as provided below.
    (g) Before making any reduction in assessments of its own motion, the board of review shall give notice to the assessor or chief county assessment officer who certified the assessment, and give the assessor or chief county assessment officer an opportunity to be heard thereon.
    (h) All complaints of errors in assessments of property shall be in writing, and shall be filed by the complaining party with the board of review, in the number of copies required by board of review rule. A copy shall be filed by the board of review with the assessor or chief county assessment officer who certified the assessment.
    (i) In all cases where a change in assessed valuation of $100,000 or more is sought, the board of review shall also serve a copy of the petition on all taxing districts as shown on the last available tax bill at least 14 days prior to the hearing on the complaint. Service may be by electronic means if the taxing district consents to electronic service and provides the board of review with a valid e-mail address for the purpose of receiving service. All taxing districts shall have an opportunity to be heard on the complaint. A taxing district wishing to intervene shall file a request to intervene with the board of review at least five days in advance of a scheduled hearing. If board of review rules require the appellant to submit evidence in advance of a hearing, then any evidence in support of the intervenor's opinion of assessed value must be submitted to the board of review and complainant no later than five calendar days prior to the hearing. Service shall be made as set forth in subsection (d-5), but if board of review rules allow complaints and correspondence to be transmitted electronically, then the intervenor's evidence shall be transmitted electronically.
    (i-5) If board of review rules require the appellant to submit evidence in advance of a hearing, then any evidence to support the assessor's opinion of assessed value must be submitted to the board of review and the complainant (or, if represented by an attorney, to the attorney) no later than five calendar days prior to the hearing. Service shall be made as set forth in subsection (d-5), but if board of review rules allow complaints and correspondence to be transmitted electronically, then the assessor's evidence shall be transmitted electronically.
    (j) Complaints shall be classified by townships or taxing districts by the clerk of the board of review. All classes of complaints shall be docketed numerically, each in its own class, in the order in which they are presented, in books kept for that purpose, which books shall be open to public inspection. Complaints shall be considered by townships or taxing districts until all complaints have been heard and passed upon by the board.

    (35 ILCS 200/16-60)
    Sec. 16-60. Equalization within counties - Publication and hearing. After notice and hearing as required by Section 12-40, the board of review may increase or reduce the entire assessment, or the assessment of any class included therein, if, in its opinion, the assessment has not been made upon the proper basis. The board may also equalize the assessment in any multi-township or township, or part thereof, or any portion of the county.
(Source: P.A. 86-345; 86-413; 86-1028; 86-1481; 88-455.)

35 ILCS 200/16-65

    (35 ILCS 200/16-65)
    Sec. 16-65. Equalization process. The board of review shall act as an equalizing authority, if after equalization by the supervisor of assessments the equalized assessed value of property in the county is not 33 1/3% of the total fair cash value. The board shall, after notice and hearing as required by Section 12-40, lower or raise the total assessed value of property in any assessment district within the county so that the property, other than farm and coal property assessed under Sections 10-110 through 10-140 and Sections 10-170 through 10-200, will be assessed at 33 1/3% of its fair cash value.
    For each assessment district of the county, the board of review shall annually determine the percentage relationship between the valuations at which property other than farm and coal property is listed and the estimated 33 1/3% of the fair cash value of such property. To make this analysis, the board shall use at least 25 property transfers, or a combination of at least 25 property transfers and property appraisals, such information as may be submitted by interested taxing bodies, or any other means as it deems proper and reasonable. If there are not 25 property transfers available, or if these 25 property transfers do not represent a fair sample of the types of properties and their proportional distribution in the assessment district, the board shall select a random sample of properties of a number necessary to provide a combination of at least 25 property transfers and property appraisals as much as possible representative of the entire assessment district, and provide for their appraisal. The township or multi-township assessor shall be notified of and participate in the deliberations and determinations.
    In assessment year 2011, the board of review shall consider compulsory sales in its equalization process.
    The board of review, in conjunction with the chief county assessment officer, shall determine the number of compulsory sales from the prior year for the purpose of revising and correcting assessments. The board of review shall determine if the number of compulsory sales is at least 25% of all property transfers within the neighborhood, township, multi-township assessment district, or other specific geographic region in the county for that class of property, but shall exclude from the calculation (i) all property transfers for which the property characteristics and condition are not the same as those characteristics and condition used to determine the assessed value and (ii) any property transfer that is not an arm's length transaction based on existing sales ratio study standards (except for compulsory sales). If the board determines that the number of compulsory sales is at least 25% of all property transfers within the defined geographic region for that class of property, then the board of review must determine (i) the median assessment level of arm's length transactions and (ii) the median assessment level of compulsory sales. If the median assessment level of compulsory sales is higher than the median assessment level of arm's length transactions, then compulsory sales shall be included in the arm's length transaction study and the board must calculate the new median assessment level. Assessed values of properties within the specific geographic area for that class of property must be revised to reflect this new median assessment level. The revised median assessment level shall be the basis for equalization as otherwise provided in this Section.
    With the ratio determined for each assessment district, the board shall ascertain the amount to be added or deducted from the aggregate assessment on property subject to local assessment jurisdiction, other than farm and coal property, to produce a ratio of assessed value to 33 1/3% of the fair cash value equivalent to 100%. However, in determining the amount to be added to the aggregate assessment on property subject to local jurisdiction in order to produce a ratio of assessed value to 33 1/3% of the fair cash value equivalent to 100%, the board shall not, in any one year, increase or decrease the aggregate assessment of any assessment district by more than 25% of the equalized valuation of the district for the previous year, except that additions, deletions or depletions to the taxable property shall be excluded in computing the 25% limitation. The board shall complete the equalization by the date prescribed in Section 16-35 for the board's adjournment, and, within 10 days thereafter, shall report the results of its work under this Section to the Department. At least 30 days prior to its adjournment, the board shall publish a notice declaring whether it intends to equalize assessments as provided in this Section. The notice shall be published in a newspaper of general circulation in the county. If the board fails to report to the Department within the required time, or if the report discloses that the board has failed to make a proper and adequate equalization of assessments, the Department shall direct, determine, and supervise the assessment so that all assessments of property are relatively just and equal as provided in Section 8-5.

    (35 ILCS 200/16-70)
    Sec. 16-70. Determination of exemptions. The board of review shall hear and determine the application of any person who is assessed on property claimed to be exempt from taxation. However, the decision of the board shall not be final, except as to homestead exemptions. Upon filing of any application for a non-homestead exemption which would reduce the assessed valuation of any property by more than $100,000, the owner shall deliver, in person or by mail, a copy of the application to any municipality, school district, community college district, and fire protection district in which the property is situated. Failure of a municipality, school district, community college district, or fire protection district to receive the notice shall not invalidate any exemption. The board shall give the municipalities, school districts, community college districts, fire protection districts, and the taxpayer an opportunity to be heard. The clerk of the board in all cases other than homestead exemptions, under the direction of the board, shall make out and forward to the Department, a full and complete statement of all the facts in the case. The Department shall determine whether the property is legally liable to taxation. It shall notify the board of review of its decision, and the board shall correct the assessment if necessary. The decision of the Department is subject to review under Sections 8-35 and 8-40. The extension of taxes on any assessment shall not be delayed by any proceedings under this Section, and, if the Department rules that the property is exempt, any taxes extended upon the unauthorized assessment shall be abated or, if paid, shall be refunded.

    Sec. 16-75. Certificates of error. The board of review shall, at any time before judgment, if an error or mistake is discovered (other than errors of judgment as to the valuation), in any assessment, issue to the person erroneously assessed a certificate setting forth the nature of the error and its cause or causes. The certificate when properly endorsed by the chief county assessment officer, showing concurrence therein, and not otherwise, may be used in evidence in any court of competent jurisdiction, and when so introduced in evidence, shall become a part of the court records, and shall not be removed from the files except upon the order of the court.
    After the board of review has issued a certificate of error and it has been properly endorsed by the chief county assessment officer, 2 copies of the certificate shall be made and one copy given to the county clerk and one copy to the collector. The county clerk shall keep records of the changes or corrections made in the certificate and shall certify such corrections to the collector so that he or she can account for the proper amount of taxes chargeable to him or her.

In any county with fewer than 3,000,000 inhabitants, if the board of review lowers the assessment of a particular parcel on which a residence occupied by the owner is situated, the reduced assessment, subject to equalization, shall remain in effect for the remainder of the general assessment period as provided in Sections 9-215 through 9-225, unless the taxpayer, county assessor, or other interested party can show substantial cause why the reduced assessment should not remain in effect, or unless the decision of the board is reversed or modified upon review.
