Illinois Compiled Statutes

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

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

35 ILCS 200/15-178

    (35 ILCS 200/15-178)
    Sec. 15-178. Reduction in assessed value for affordable rental housing construction or rehabilitation.
    (a) The General Assembly finds that there is a shortage of high quality affordable rental homes for low-income and very-low-income households throughout Illinois; that owners and developers of rental housing face significant challenges building newly constructed apartments or undertaking rehabilitation of existing properties that results in rents that are affordable for low-income and very-low-income households; and that it will help Cook County and other parts of Illinois address the extreme shortage of affordable rental housing by developing a statewide policy to determine the assessed value for newly constructed and rehabilitated affordable rental housing that both encourages investment and incentivizes property owners to keep rents affordable.
    (b) Each chief county assessment officer shall implement special assessment programs to reduce the assessed value of all eligible newly constructed residential real property or qualifying rehabilitation to all eligible existing residential real property in accordance with subsection (c) for 10 taxable years after the newly constructed residential real property or improvements to existing residential real property are put in service. Any county with less than 3,000,000 inhabitants may decide not to implement one or both of the special assessment programs defined in subparagraph (1) of subsection (c) of this Section and subparagraph (2) of subsection (c) of this Section upon passage of an ordinance by a majority vote of the county board. Subsequent to a vote to opt out of this special assessment program, any county with less than 3,000,000 inhabitants may decide to implement one or both of the special assessment programs defined in subparagraph (1) of subsection (c) of this Section and subparagraph (2) of subsection (c) of this Section upon passage of an ordinance by a majority vote of the county board. Property is eligible for the special assessment program if and only if all of the following factors have been met:
        (1) at the conclusion of the new construction or
    
qualifying rehabilitation, the property consists of a newly constructed multifamily building containing 7 or more rental dwelling units or an existing multifamily building that has undergone qualifying rehabilitation resulting in 7 or more rental dwelling units; and
        (2) the property meets the application requirements
    
defined in subsection (f).
    (c) For those counties that are required to implement the special assessment program and do not opt out of such special assessment program, the chief county assessment officer for that county shall require that residential real property is eligible for the special assessment program if and only if one of the additional factors have been met:
        (1) except as defined in subparagraphs (E), (F), and
    
(G) of paragraph (1) of subsection (f) of this Section, prior to the newly constructed residential real property or improvements to existing residential real property being put in service, the owner of the residential real property commits that, for a period of 10 years, at least 15% of the multifamily building's units will have rents as defined in this Section that are at or below maximum rents and are occupied by households with household incomes at or below maximum income limits; or
        (2) except as defined in subparagraphs (E), (F), and
    
(G) of paragraph (1) of subsection (f) of this Section, prior to the newly constructed residential real property or improvements to existing residential real property located in a low affordability community being put in service, the owner of the residential real property commits that, for a period of 30 years after the newly constructed residential real property or improvements to existing residential real property are put in service, at least 20% of the multifamily building's units will have rents as defined in this Section that are at or below maximum rents and are occupied by households with household incomes at or below maximum income limits.
    If a reduction in assessed value is granted under one special assessment program provided for in this Section, then that same residential real property is not eligible for an additional special assessment program under this Section at the same time.
    (d) The amount of the reduction in assessed value for residential real property meeting the conditions set forth in subparagraph (1) of subsection (c) shall be calculated as follows:
        (1) if the owner of the residential real property
    
commits for a period of at least 10 years that at least 15% but fewer than 35% of the multifamily building's units have rents at or below maximum rents and are occupied by households with household incomes at or below maximum income limits, the assessed value of the property used to calculate the tax bill shall be reduced by an amount equal to 25% of the assessed value of the property as determined by the assessor for the property in the current taxable year for the newly constructed residential real property or based on the improvements to an existing residential real property; and
        (2) if the owner of the residential real property
    
commits for a period of at least 10 years that at least 35% of the multifamily building's units have rents at or below maximum rents and are occupied by households with household incomes at or below maximum income limits, the assessed value of the property used to calculate the tax bill shall be reduced by an amount equal to 35% of the assessed value of the property as determined by the assessor for the property in the current assessment year for the newly constructed residential real property or based on the improvements to an existing residential real property.
    (e) The amount of the reduction for residential real property meeting the conditions set forth in subparagraph (2) of subsection (c) shall be calculated as follows:
        (1) for the first, second, and third taxable year
    
after the residential real property is placed in service, the residential real property is entitled to a reduction in its assessed value in an amount equal to the difference between the assessed value in the year for which the incentive is sought and the assessed value for the residential real property in the base year;
        (2) for the fourth, fifth, and sixth taxable year
    
after the residential real property is placed in service, the property is entitled to a reduction in its assessed value in an amount equal to 80% of the difference between the assessed value in the year for which the incentive is sought and the assessed value for the residential real property in the base year;
        (3) for the seventh, eighth, and ninth taxable year
    
after the property is placed in service, the residential real property is entitled to a reduction in its assessed value in an amount equal to 60% of the difference between the assessed value in the year for which the incentive is sought and the assessed value for the residential real property in the base year;
        (4) for the tenth, eleventh, and twelfth taxable year
    
after the residential real property is placed in service, the residential real property is entitled to a reduction in its assessed value in an amount equal to 40% of the difference between the assessed value in the year for which the incentive is sought and the assessed value for the residential real property in the base year; and
        (5) for the thirteenth through the thirtieth taxable
    
year after the residential real property is placed in service, the residential real property is entitled to a reduction in its assessed value in an amount equal to 20% of the difference between the assessed value in the year for which the incentive is sought and the assessed value for the residential real property in the base year.

            (A) The owner is eligible to apply for the
        
reduced valuation conferred by this Section beginning in the first assessment year after the effective date of this amendatory Act of the 102nd General Assembly through December 31, 2027. If approved, the reduction will be effective for the current assessment year, which will be reflected in the tax bill issued in the following calendar year. Owners that are approved for the reduced valuation under paragraph (1) of subsection (c) of this Section before December 31, 2027 shall, at minimum, be eligible for annual renewal of the reduced valuation during an initial 10-year period if annual certification requirements are met for each of the 10 years, as described in subparagraph (B) of paragraph (4) of subsection (d) of this Section.

However, the initial 10-year eligibility period or 30-year eligibility period, depending on the applicable program, shall be reduced by the number of years between the placed in service date and the date the owner first receives this reduced valuation.
            (F) The owner may apply for the reduced valuation
        
within 2 years after the newly constructed residential real property or improvements to existing residential real property are put in service. However, the initial 10-year eligibility period or 30-year eligibility period, depending on the applicable program, shall be reduced for the number of years between the placed in service date and the date the owner first receives this reduced valuation.
            (G) Owners of a multifamily building receiving a
        
reduced valuation through the Cook County Class 9 program during the year in which this amendatory Act of the 102nd General Assembly takes effect shall be deemed automatically eligible for the reduced valuation defined in paragraph (1) of subsection (c) of this Section in terms of meeting the criteria for new construction or substantial rehabilitation for a specific multifamily building regardless of when the newly constructed residential real property or improvements to existing residential real property were put in service. If a Cook County Class 9 owner had Class 9 status revoked on or after January 1, 2017 but can provide documents sufficient to prove that the revocation was in error or any deficiencies leading to the revocation have been cured, the chief county assessment officer may deem the owner to be eligible. However, owners may not receive both the reduced valuation under this Section and the reduced valuation under the Cook County Class 9 program in any single assessment year. In addition, the number of years during which an owner has participated in the Class 9 program shall count against the 3 10-year periods of eligibility for the reduced valuation as defined in subparagraph (1) of subsection (c) of this Section.
            (H) At the completion of the assessment reduction
        
period described in this Section: the entire parcel will be assessed as otherwise provided by law.

    "Low affordability community" means (1) a municipality or jurisdiction with less than 1,000,000 inhabitants in which 40% or less of its total year-round housing units are affordable, as determined by the Illinois Housing Development Authority during the exemption determination process under the Affordable Housing Planning and Appeal Act; (2) "D" zoning districts as now or hereafter designated in the Chicago Zoning Ordinance; or (3) a jurisdiction located in a municipality with 1,000,000 or more inhabitants that has been designated as a low affordability community by passage of a local ordinance by that municipality, specifying the census tract or property by permanent index number or numbers.
    "Maximum income limits" means the maximum regular income limits for 60% of area median income for the geographic area in which the multifamily building is located for multifamily programs as determined by the United States Department of Housing and Urban Development and published annually by the Illinois Housing Development Authority. A property may be deemed to have satisfied the maximum income limits with a weighted average if municipal, state, or federal laws, ordinances, rules, or regulations requires the use of a weighted average of no more than 60% of area median income for that property.
    "Maximum rent" means the maximum regular rent for 60% of the area median income for the geographic area in which the multifamily building is located for multifamily programs as determined by the United States Department of Housing and Urban Development and published annually by the Illinois Housing Development Authority. To be eligible for the reduced valuation defined in this Section, maximum rents are to be consistent with the Illinois Housing Development Authority's rules; or if the owner is leasing an affordable unit to a household with an income at or below the maximum income limit who is participating in qualifying income-based rental subsidy program, "maximum rent" means the maximum rents allowable under the guidelines of the qualifying income-based rental subsidy program. A property may be deemed to have satisfied the maximum rent with a weighted average if municipal, state, or federal laws, ordinances, rules, or regulations requires the use of a weighted average of no more than 60% of area median income for that property.
    "Qualifying income-based rental subsidy program" means a Housing Choice Voucher issued by a housing authority under Section 8 of the United States Housing Act of 1937, a tenant voucher converted to a project-based voucher by a housing authority or any other program administered or funded by a housing authority, the Illinois Housing Development Authority, another State agency, a federal agency, or a unit of local government where participation is limited to households with incomes at or below the maximum income limits as defined in this Section and the tenants' portion of the rent payment is based on a percentage of their income or a flat amount that does not exceed the maximum rent as defined in this Section.
    "Qualifying rehabilitation" means, at a minimum, compliance with local building codes and the replacement or renovation of at least 2 primary building systems to be approved for the reduced valuation under paragraph (1) of subsection (d) of this Section and at least 5 primary building systems to be approved for the reduced valuation under subsection (e) of 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.

Property shall no longer be exempt under this subsection as of the date when the right of the municipality or unit of local government to use, control, and possess the property or to require the performance of services is terminated and the municipality or unit of local government no longer has any option to purchase or otherwise reacquire the interest in the property which was transferred by the municipality or unit of local government.
    (b) Notwithstanding anything in this Code to the contrary, all property owned by a municipality with a population of over 500,000 inhabitants, a unit of local government whose jurisdiction includes territory located in whole or in part within a municipality with a population of over 500,000 inhabitants, or a municipality with home rule powers that is contiguous to a municipality with a population of over 500,000 inhabitants, shall remain exempt from taxation and any leasehold interest in that property is not subject to taxation under Section 9-195 if the property, including dedicated public property, is used by a municipality or other unit of local government for the purpose of parking and is leased for continued use for the same purpose to another entity whose property is not exempt. If property located in a municipality with a population of more than 500,000 inhabitants is not subject to taxation due to its use for the purpose of parking, and any portion of the property is used for a purpose other than parking, that portion of the property shall be subject to taxation under Section 9-195 for the period of time during which it is used for that non-exempt purpose; provided, however, that the use of a portion of such property for a non-exempt purpose shall have no effect on (i) the exemption of the remaining portion of the property that continues to be used for an exempt purpose, as identified in this subsection, or (ii) the future exemption of that same portion of the property if it ceases to be used for a non-exempt purpose and returned to use for an exempt purpose as identified in this subsection. No taxes shall be assessed on any portion of the property identified in this subsection prior to the effective date of this amendatory Act of the 101st General Assembly.
    Any transaction described under this subsection must be undertaken in accordance with all appropriate federal laws and regulations.
    (c) For purposes of this Section, "municipality" means a municipality as defined in Section 1-1-2 of the Illinois Municipal Code, and "unit of local government" means a unit of local government as defined in Article VII, Section 1 of the Constitution of the State of Illinois. The provisions of this Section supersede and control over any conflicting provisions of this Code.

    (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).

Upon request by the board of appeals (until the first Monday in December 1998 and the board of review beginning the first Monday in December 1998 and thereafter), the officer shall immediately furnish all of the requested records to the board. The records shall be available, on request, to the taxpayer. The chief county assessment officer shall certify, in writing, the amount of the assessment to the board. If the records maintained by the chief county assessment officer at the time the assessment is certified to the board under subsection (a) contain none of the elements (or basis) of valuation for the parcel, then any increase by the chief county assessment officer shall be considered invalid by the board acting on a complaint under Section 16-120; and no action by the board under Section 16-120 shall result in an increase in the valuation for the parcel for the current assessment year.
    (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. If a taxpayer files an assessment complaint with the chief county assessment officer, the notification to the taxpayer of a determination on the assessment complaint shall designate the reason for the result.

    (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.

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.

    (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.

However, the decision of the board shall not be final, except as to homestead exemptions and exemptions provided under subsection (b) of Section 15-5. With the exception of homestead exemptions and exemptions provided under subsection (b) of Section 15-5, upon filing of any application for an 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.

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.

Whenever the board of appeals (until the first Monday in December 1998 and the board of review beginning the first Monday in December 1998 and thereafter) in any county with 3,000,000 or more inhabitants determines that any property is or is not exempt from taxation, the decision of the board shall not be final, except as to homestead exemptions and exemptions provided under subsection (b) of Section 15-5. With the exception of homestead exemptions and exemptions provided under subsection (b) of Section 15-5, upon filing of any application for an exemption which would, if approved, reduce the assessed valuation of any property by more than $100,000, other than a homestead exemption, the owner shall give timely notice of the application by mailing a copy of it to any municipality, fire protection district, school district, and community college district in which such property is situated. Failure of a municipality, fire protection district, school district, or community college district to receive the notice shall not invalidate any exemption. The board shall give the municipalities, fire protection districts, school districts, and community college districts and the taxpayer an opportunity to be heard. In all exemption cases other than homestead exemptions, the secretary of the board shall comply with the provisions of Section 5-15. The Department shall then determine whether the property is or is not legally liable to taxation. It shall notify the board of its decision and the board shall correct the assessment accordingly, 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 paragraph, and, in case the property is determined to be exempt, any taxes extended upon the unauthorized assessment shall be abated or, if already paid, shall be refunded.

    Sec. 16-135. Omitted property; Notice provisions. In counties with 3,000,000 or more inhabitants, the owner of property and the executor, administrator, or trustee of a decedent whose property has been omitted in the assessment in any year or years or on which a tax for which the property was liable has not been paid, and the several taxing bodies interested therein, shall be given at least 30 days notice in writing by the board of appeals (until the first Monday in December 1998 and the board of review beginning the first Monday in December 1998 and thereafter) or county assessor of the hearing on the proposed assessments of the omitted property. The board or assessor shall have full power to examine the owner, or the executor, administrator, trustee, legatee, or heirs of the decedent, or other person concerning the ownership, kind, character, amount and the value of the omitted property.
    If the board determines that the property of any decedent was omitted from assessment during any year or years, or that a tax for which the property was liable, has not been paid, the board shall direct the county assessor to assess the property. However, if the county assessor, on his or her own initiative, makes such a determination, then the assessor shall assess the property. No charge for tax of previous years shall be made against any property prior to the date of ownership of the person owning the property at the time the liability for such omitted tax is first ascertained. Ownership as used in this Section refers to bona fide legal and equitable titles or interests acquired for value and without notice of the tax, as may appear by deed, deed of trust, mortgage, certificate of purchase or sale, or other form of contract. No such charge for tax of previous years shall be made against any property if:
        (1) the assessor failed to notify the board of review
    
of an omitted assessment in accordance with subsection (a-1) of Section 9-260 of this Code; or
        (2) the property was last assessed as unimproved,
    
the owner of the property, gave notice of subsequent improvements and requested a reassessment as required by Section 9-180, and reassessment of the property was not made within 16 months of receipt of that notice; or
        (3) the owner of the property gave notice as required
    
by Section 9-265; or
        (4) the assessor received a building permit for the
    
property evidencing that new construction had occurred or was occurring on the property but failed to list the improvement on the tax rolls; or
        (5) the assessor received a plat map, plat of survey,
    
ALTA survey, mortgage survey, or other similar document containing the omitted property but failed to list the improvement on the tax rolls; or
        (6) the assessor received a real estate transfer
    
declaration indicating a sale from an exempt property owner to a non-exempt property owner but failed to list the property on the tax rolls; or
        (7) the property was the subject of an assessment
    
appeal before the assessor or the board of review that had included the intended omitted property as part of the assessment appeal and provided evidence of its market value.
    The assessment of omitted property by the county assessor may be reviewed by the board in the same manner as other assessments are reviewed under the provisions of this Code and when so reviewed, the assessment shall not thereafter be subject to review by any succeeding board.
    For the purpose of enforcing the provisions of this Code, relating to property omitted from assessment, the taxing bodies interested therein are hereby empowered to employ counsel to appear before the board or assessor (as the case may be) and take all necessary steps to enforce the assessment on the omitted property.

If the tax for which that property was liable has not been paid or if any property, by reason of defective description or assessment thereof, fails to pay taxes for any year or years, the property, when discovered by the board shall be listed and assessed by the county assessor. The board may order the county assessor to make such alterations in the description of property as it deems necessary. No charge for tax of previous years shall be made against any property if:
        (1) the assessor failed to notify the board of review
    
of an omitted assessment in accordance with subsection (a-1) of Section 9-260 of this Code; or
        (2) the property was last assessed as unimproved,
    
the owner of the property gave notice of subsequent improvements and requested a reassessment as required by Section 9-180, and reassessment of the property was not made within 16 months of receipt of that notice; or
        (3) the owner of the property gave notice as required
    
by Section 9-265; or
        (4) the assessor received a building permit for the
    
property evidencing that new construction had occurred or was occurring on the property but failed to list the improvement on the tax rolls; or
        (5) the assessor received a plat map, plat of survey,
    
ALTA survey, mortgage survey, or other similar document containing the omitted property but failed to list the improvement on the tax rolls; or

declaration indicating a sale from an exempt property owner to a non-exempt property owner but failed to list the property on the tax rolls; or

In counties with 3,000,000 or more inhabitants, beginning with assessments made for the 1996 assessment year for residential property of 6 units or less and beginning with assessments made for the 1997 assessment year for all other property, and for all property in any county other than a county with 3,000,000 or more inhabitants, any taxpayer dissatisfied with the decision of a board of review or board of appeals as such decision pertains to the assessment of his or her property for taxation purposes, or any taxing body that has an interest in the decision of the board of review or board of appeals on an assessment made by any local assessment officer, may, (i) in counties with less than 3,000,000 inhabitants within 30 days after the date of written notice of the decision of the board of review or (ii) in assessment year 1999 and thereafter in counties with 3,000,000 or more inhabitants within 30 days after the date of the board of review notice or within 30 days after the date that the board of review transmits to the county assessor pursuant to Section 16-125 its final action on the township in which the property is located, whichever is later, appeal the decision to the Property Tax Appeal Board for review. In any appeal where the board of review or board of appeals has given written notice of the hearing to the taxpayer 30 days before the hearing, failure to appear at the board of review or board of appeals hearing shall be grounds for dismissal of the appeal unless a continuance is granted to the taxpayer. If an appeal is dismissed for failure to appear at a board of review or board of appeals hearing, the Property Tax Appeal Board shall have no jurisdiction to hear any subsequent appeal on that taxpayer's complaint. Such taxpayer or taxing body, hereinafter called the appellant, shall file a petition with the clerk of the Property Tax Appeal Board, setting forth the facts upon which he or she bases the objection, together with a statement of the contentions of law which he or she desires to raise, and the relief requested. If a petition is filed by a taxpayer, the taxpayer is precluded from filing objections based upon valuation, as may otherwise be permitted by Sections 21-175 and 23-5. However, any taxpayer not satisfied with the decision of the board of review or board of appeals as such decision pertains to the assessment of his or her property need not appeal the decision to the Property Tax Appeal Board before seeking relief in the courts. The changes made by this amendatory Act of the 91st General Assembly shall be effective beginning with the 1999 assessment year.
    An association may, on behalf of all or several of the owners that constitute the association, file an appeal to the Property Tax Appeal Board or intervene in an appeal to the Property Tax Appeal Board filed by a taxing body. For purposes of this Section, "association" means: (1) a common interest community association, as that term is defined in Section 1-5 of the Common Interest Community Association Act; (2) a unit owners' association, as that term is defined in subsection (o) of Section 2 of the Condominium Property Act; or (3) a master association, as that term is defined in subsection (u) of Section 2 of the Condominium Property Act.

The procedure, to the extent that the Board considers practicable, shall eliminate formal rules of pleading, practice and evidence, and except for any reasonable filing fee determined by the Board, may provide that costs shall be in the discretion of the Board.

The chairman of the Property Tax Appeal Board shall provide for the speedy hearing of all such appeals. Each appeal shall be limited to the grounds listed in the petition filed with the Property Tax Appeal Board. All appeals shall be considered de novo and the Property Tax Appeal Board shall not be limited to the evidence presented to the board of review of the county. A party participating in the hearing before the Property Tax Appeal Board is entitled to introduce evidence that is otherwise proper and admissible without regard to whether that evidence has previously been introduced at a hearing before the board of review of the county. Where no complaint has been made to the board of review of the county where the property is located and the appeal is based solely on the effect of an equalizing factor assigned to all property or to a class of property by the board of review, the Property Tax Appeal Board shall not grant a reduction in assessment greater than the amount that was added as the result of the equalizing factor.

The Board shall make a decision in each appeal or case appealed to it, and the decision shall be based upon equity and the weight of evidence and not upon constructive fraud, and shall be binding upon appellant and officials of government. The extension of taxes on any assessment so appealed shall not be delayed by any proceeding before the Board, and, in case the assessment is altered by the Board, any taxes extended upon the unauthorized assessment or part thereof shall be abated, or, if already paid, shall be refunded with interest as provided in Section 23-20.
    The decision or order of the Property Tax Appeal Board in any such appeal, shall, within 10 days thereafter, be certified at no charge to the appellant and to the proper authorities, including the board of review or board of appeals whose decision was appealed, the county clerk who extends taxes upon the assessment in question, and the county collector who collects property taxes upon such assessment.
    The final administrative decision of the Property Tax Appeal Board shall be deemed served on a party when a copy of the decision is: (1) deposited in the United States Mail, in a sealed package, with postage prepaid, addressed to that party at the address listed for that party in the pleadings; except that, if the party is represented by an attorney, the notice shall go to the attorney at the address listed in the pleadings; or (2) sent electronically to the party at the e-mail addresses provided for that party in the pleadings. The Property Tax Appeal Board shall allow each party to designate one or more individuals to receive electronic correspondence on behalf of that party and shall allow each party to change, add, or remove designees selected by that party during the course of the proceedings. Decisions and all electronic correspondence shall be directed to each individual so designated.
    If the Property Tax Appeal Board renders a decision lowering the assessment of a particular parcel after the deadline for filing complaints with the board of review or board of appeals or after adjournment of the session of the board of review or board of appeals at which assessments for the subsequent year or years of the same general assessment period, as provided in Sections 9-215 through 9-225, are being considered, the taxpayer may, within 30 days after the date of written notice of the Property Tax Appeal Board's decision, appeal the assessment for such subsequent year or years directly to the Property Tax Appeal Board.
    If the Property Tax Appeal Board renders a decision lowering the assessment of a particular parcel on which a residence occupied by the owner is situated, such 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 that parcel is subsequently sold in an arm's length transaction establishing a fair cash value for the parcel that is different from the fair cash value on which the Board's assessment is based, or unless the decision of the Property Tax Appeal Board is reversed or modified upon review.
