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 200/18-185)
    Sec. 18-185. Short title; definitions. This Division 5 may be cited as the Property Tax Extension Limitation Law. As used in this Division 5:
    "Consumer Price Index" means the Consumer Price Index for All Urban Consumers for all items published by the United States Department of Labor.
    "Extension limitation" means (a) the lesser of 5% or the percentage increase in the Consumer Price Index during the 12-month calendar year preceding the levy year or (b) the rate of increase approved by voters under Section 18-205.
    "Affected county" means a county of 3,000,000 or more inhabitants or a county contiguous to a county of 3,000,000 or more inhabitants.
    "Taxing district" has the same meaning provided in Section 1-150, except as otherwise provided in this Section. For the 1991 through 1994 levy years only, "taxing district" includes only each non-home rule taxing district having the majority of its 1990 equalized assessed value within any county or counties contiguous to a county with 3,000,000 or more inhabitants. Beginning with the 1995 levy year, "taxing district" includes only each non-home rule taxing district subject to this Law before the 1995 levy year and each non-home rule taxing district not subject to this Law before the 1995 levy year having the majority of its 1994 equalized assessed value in an affected county or counties. Beginning with the levy year in which this Law becomes applicable to a taxing district as provided in Section 18-213, "taxing district" also includes those taxing districts made subject to this Law as provided in Section 18-213.
    "Aggregate extension" for taxing districts to which this Law applied before the 1995 levy year means the annual corporate extension for the taxing district and those special purpose extensions that are made annually for the taxing district, excluding special purpose extensions: (a) made for the taxing district to pay interest or principal on general obligation bonds that were approved by referendum; (b) made for any taxing district to pay interest or principal on general obligation bonds issued before October 1, 1991; (c) made for any taxing district to pay interest or principal on bonds issued to refund or continue to refund those bonds issued before October 1, 1991; (d) made for any taxing district to pay interest or principal on bonds issued to refund or continue to refund bonds issued after October 1, 1991 that were approved by referendum; (e) made for any taxing district to pay interest or principal on revenue bonds issued before October 1, 1991 for payment of which a property tax levy or the full faith and credit of the unit of local government is pledged; however, a tax for the payment of interest or principal on those bonds shall be made only after the governing body of the unit of local government finds that all other sources for payment are insufficient to make those payments; (f) made for payments under a building commission lease when the lease payments are for the retirement of bonds issued by the commission before October 1, 1991, to pay for the building project; (g) made for payments due under installment contracts entered into before October 1, 1991; (h) made for payments of principal and interest on bonds issued under the Metropolitan Water Reclamation District Act to finance construction projects initiated before October 1, 1991; (i) made for payments of principal and interest on limited bonds, as defined in Section 3 of the Local Government Debt Reform Act, in an amount not to exceed the debt service extension base less the amount in items (b), (c), (e), and (h) of this definition for non-referendum obligations, except obligations initially issued pursuant to referendum; (j) made for payments of principal and interest on bonds issued under Section 15 of the Local Government Debt Reform Act; (k) made by a school district that participates in the Special Education District of Lake County, created by special education joint agreement under Section 10-22.31 of the School Code, for payment of the school district's share of the amounts required to be contributed by the Special Education District of Lake County to the Illinois Municipal Retirement Fund under Article 7 of the Illinois Pension Code; the amount of any extension under this item (k) shall be certified by the school district to the county clerk; (l) made to fund expenses of providing joint recreational programs for persons with disabilities under Section 5-8 of the Park District Code or Section 11-95-14 of the Illinois Municipal Code; (m) made for temporary relocation loan repayment purposes pursuant to Sections 2-3.77 and 17-2.2d of the School Code; (n) made for payment of principal and interest on any bonds issued under the authority of Section 17-2.2d of the School Code; (o) made for contributions to a firefighter's pension fund created under Article 4 of the Illinois Pension Code, to the extent of the amount certified under item (5) of Section 4-134 of the Illinois Pension Code; and (p) made for road purposes in the first year after a township assumes the rights, powers, duties, assets, property, liabilities, obligations, and responsibilities of a road district abolished under the provisions of Section 6-133 of the Illinois Highway Code.
    "Aggregate extension" for the taxing districts to which this Law did not apply before the 1995 levy year (except taxing districts subject to this Law in accordance with Section 18-213) means the annual corporate extension for the taxing district and those special purpose extensions that are made annually for the taxing district, excluding special purpose extensions: (a) made for the taxing district to pay interest or principal on general obligation bonds that were approved by referendum; (b) made for any taxing district to pay interest or principal on general obligation bonds issued before March 1, 1995; (c) made for any taxing district to pay interest or principal on bonds issued to refund or continue to refund those bonds issued before March 1, 1995; (d) made for any taxing district to pay interest or principal on bonds issued to refund or continue to refund bonds issued after March 1, 1995 that were approved by referendum; (e) made for any taxing district to pay interest or principal on revenue bonds issued before March 1, 1995 for payment of which a property tax levy or the full faith and credit of the unit of local government is pledged; however, a tax for the payment of interest or principal on those bonds shall be made only after the governing body of the unit of local government finds that all other sources for payment are insufficient to make those payments; (f) made for payments under a building commission lease when the lease payments are for the retirement of bonds issued by the commission before March 1, 1995 to pay for the building project; (g) made for payments due under installment contracts entered into before March 1, 1995; (h) made for payments of principal and interest on bonds issued under the Metropolitan Water Reclamation District Act to finance construction projects initiated before October 1, 1991; (h-4) made for stormwater management purposes by the Metropolitan Water Reclamation District of Greater Chicago under Section 12 of the Metropolitan Water Reclamation District Act; (h-8) made for payments of principal and interest on bonds issued under Section 9.6a of the Metropolitan Water Reclamation District Act to make contributions to the pension fund established under Article 13 of the Illinois Pension Code; (i) made for payments of principal and interest on limited bonds, as defined in Section 3 of the Local Government Debt Reform Act, in an amount not to exceed the debt service extension base less the amount in items (b), (c), and (e) of this definition for non-referendum obligations, except obligations initially issued pursuant to referendum and bonds described in subsections (h) and (h-8) of this definition; (j) made for payments of principal and interest on bonds issued under Section 15 of the Local Government Debt Reform Act; (k) made for payments of principal and interest on bonds authorized by Public Act 88-503 and issued under Section 20a of the Chicago Park District Act for aquarium or museum projects and bonds issued under Section 20a of the Chicago Park District Act for the purpose of making contributions to the pension fund established under Article 12 of the Illinois Pension Code; (l) made for payments of principal and interest on bonds authorized by Public Act 87-1191 or 93-601 and (i) issued pursuant to Section 21.2 of the Cook County Forest Preserve District Act, (ii) issued under Section 42 of the Cook County Forest Preserve District Act for zoological park projects, or (iii) issued under Section 44.1 of the Cook County Forest Preserve District Act for botanical gardens projects; (m) made pursuant to Section 34-53.5 of the School Code, whether levied annually or not; (n) made to fund expenses of providing joint recreational programs for persons with disabilities under Section 5-8 of the Park District Code or Section 11-95-14 of the Illinois Municipal Code; (o) made by the Chicago Park District for recreational programs for persons with disabilities under subsection (c) of Section 7.06 of the Chicago Park District Act; (p) made for contributions to a firefighter's pension fund created under Article 4 of the Illinois Pension Code, to the extent of the amount certified under item (5) of Section 4-134 of the Illinois Pension Code; (q) made by Ford Heights School District 169 under Section 17-9.02 of the School Code; and (r) made for the purpose of making employer contributions to the Public School Teachers' Pension and Retirement Fund of Chicago under Section 34-53 of the School Code.

The extension for a special service area is not included in the aggregate extension.
    "Aggregate extension base" means the taxing district's last preceding aggregate extension as adjusted under Sections 18-135, 18-215, 18-230, 18-206, and 18-233. Beginning with levy year 2022, for taxing districts that are specified in Section 18-190.7, the taxing district's aggregate extension base shall be calculated as provided in Section 18-190.7. An adjustment under Section 18-135 shall be made for the 2007 levy year and all subsequent levy years whenever one or more counties within which a taxing district is located (i) used estimated valuations or rates when extending taxes in the taxing district for the last preceding levy year that resulted in the over or under extension of taxes, or (ii) increased or decreased the tax extension for the last preceding levy year as required by Section 18-135(c). Whenever an adjustment is required under Section 18-135, the aggregate extension base of the taxing district shall be equal to the amount that the aggregate extension of the taxing district would have been for the last preceding levy year if either or both (i) actual, rather than estimated, valuations or rates had been used to calculate the extension of taxes for the last levy year, or (ii) the tax extension for the last preceding levy year had not been adjusted as required by subsection (c) of Section 18-135.
    Notwithstanding any other provision of law, for levy year 2012, the aggregate extension base for West Northfield School District No. 31 in Cook County shall be $12,654,592.
    Notwithstanding any other provision of law, for levy year 2022, the aggregate extension base of a home equity assurance program that levied at least $1,000,000 in property taxes in levy year 2019 or 2020 under the Home Equity Assurance Act shall be the amount that the program's aggregate extension base for levy year 2021 would have been if the program had levied a property tax for levy year 2021.
    "Levy year" has the same meaning as "year" under Section 1-155.
    "New property" means (i) the assessed value, after final board of review or board of appeals action, of new improvements or additions to existing improvements on any parcel of real property that increase the assessed value of that real property during the levy year multiplied by the equalization factor issued by the Department under Section 17-30, (ii) the assessed value, after final board of review or board of appeals action, of real property not exempt from real estate taxation, which real property was exempt from real estate taxation for any portion of the immediately preceding levy year, multiplied by the equalization factor issued by the Department under Section 17-30, including the assessed value, upon final stabilization of occupancy after new construction is complete, of any real property located within the boundaries of an otherwise or previously exempt military reservation that is intended for residential use and owned by or leased to a private corporation or other entity, (iii) in counties that classify in accordance with Section 4 of Article IX of the Illinois Constitution, an incentive property's additional assessed value resulting from a scheduled increase in the level of assessment as applied to the first year final board of review market value, and (iv) any increase in assessed value due to oil or gas production from an oil or gas well required to be permitted under the Hydraulic Fracturing Regulatory Act that was not produced in or accounted for during the previous levy year. In addition, the county clerk in a county containing a population of 3,000,000 or more shall include in the 1997 recovered tax increment value for any school district, any recovered tax increment value that was applicable to the 1995 tax year calculations.
    "Qualified airport authority" means an airport authority organized under the Airport Authorities Act and located in a county bordering on the State of Wisconsin and having a population in excess of 200,000 and not greater than 500,000.
    "Recovered tax increment value" means, except as otherwise provided in this paragraph, the amount of the current year's equalized assessed value, in the first year after a municipality terminates the designation of an area as a redevelopment project area previously established under the Tax Increment Allocation Redevelopment Act in the Illinois Municipal Code, previously established under the Industrial Jobs Recovery Law in the Illinois Municipal Code, previously established under the Economic Development Project Area Tax Increment Act of 1995, or previously established under the Economic Development Area Tax Increment Allocation Act, of each taxable lot, block, tract, or parcel of real property in the redevelopment project area over and above the initial equalized assessed value of each property in the redevelopment project area. For the taxes which are extended for the 1997 levy year, the recovered tax increment value for a non-home rule taxing district that first became subject to this Law for the 1995 levy year because a majority of its 1994 equalized assessed value was in an affected county or counties shall be increased if a municipality terminated the designation of an area in 1993 as a redevelopment project area previously established under the Tax Increment Allocation Redevelopment Act in the Illinois Municipal Code, previously established under the Industrial Jobs Recovery Law in the Illinois Municipal Code, or previously established under the Economic Development Area Tax Increment Allocation Act, by an amount equal to the 1994 equalized assessed value of each taxable lot, block, tract, or parcel of real property in the redevelopment project area over and above the initial equalized assessed value of each property in the redevelopment project area. In the first year after a municipality removes a taxable lot, block, tract, or parcel of real property from a redevelopment project area established under the Tax Increment Allocation Redevelopment Act in the Illinois Municipal Code, the Industrial Jobs Recovery Law in the Illinois Municipal Code, or the Economic Development Area Tax Increment Allocation Act, "recovered tax increment value" means the amount of the current year's equalized assessed value of each taxable lot, block, tract, or parcel of real property removed from the redevelopment project area over and above the initial equalized assessed value of that real property before removal from the redevelopment project area.
    Except as otherwise provided in this Section, "limiting rate" means a fraction the numerator of which is the last preceding aggregate extension base times an amount equal to one plus the extension limitation defined in this Section and the denominator of which is the current year's equalized assessed value of all real property in the territory under the jurisdiction of the taxing district during the prior levy year. For those taxing districts that reduced their aggregate extension for the last preceding levy year, except for school districts that reduced their extension for educational purposes pursuant to Section 18-206, the highest aggregate extension in any of the last 3 preceding levy years shall be used for the purpose of computing the limiting rate. The denominator shall not include new property or the recovered tax increment value. If a new rate, a rate decrease, or a limiting rate increase has been approved at an election held after March 21, 2006, then (i) the otherwise applicable limiting rate shall be increased by the amount of the new rate or shall be reduced by the amount of the rate decrease, as the case may be, or (ii) in the case of a limiting rate increase, the limiting rate shall be equal to the rate set forth in the proposition approved by the voters for each of the years specified in the proposition, after which the limiting rate of the taxing district shall be calculated as otherwise provided. In the case of a taxing district that obtained referendum approval for an increased limiting rate on March 20, 2012, the limiting rate for tax year 2012 shall be the rate that generates the approximate total amount of taxes extendable for that tax year, as set forth in the proposition approved by the voters; this rate shall be the final rate applied by the county clerk for the aggregate of all capped funds of the district for tax year 2012.

35 ILCS 200/18-190

    (35 ILCS 200/18-190)
    Sec. 18-190. Direct referendum; new rate or increased limiting rate.
    (a) If a new rate is authorized by statute to be imposed without referendum or is subject to a backdoor referendum, as defined in Section 28-2 of the Election Code, the governing body of the affected taxing district before levying the new rate shall submit the new rate to direct referendum under the provisions of this Section and of Article 28 of the Election Code. Notwithstanding any other provision of law, the levies authorized by Sections 21-110 and 21-110.1 of the Illinois Pension Code shall not be considered new rates; however, nothing in this amendatory Act of the 98th General Assembly authorizes a taxing district to increase its limiting rate or its aggregate extension without first obtaining referendum approval as provided in this Section. Notwithstanding the provisions, requirements, or limitations of any other law, any tax levied for the 2005 levy year and all subsequent levy years by any taxing district subject to this Law may be extended at a rate exceeding the rate established for that tax by referendum or statute, provided that the rate does not exceed the statutory ceiling above which the tax is not authorized to be further increased either by referendum or in any other manner. Notwithstanding the provisions, requirements, or limitations of any other law, all taxing districts subject to this Law shall follow the provisions of this Section whenever seeking referenda approval after March 21, 2006 to (i) levy a new tax rate authorized by statute or (ii) increase the limiting rate applicable to the taxing district. All taxing districts subject to this Law are authorized to seek referendum approval of each proposition described and set forth in this Section.
    The proposition seeking to obtain referendum approval to levy a new tax rate as authorized in clause (i) shall be in substantially the following form:
        Shall ... (insert legal name, number, if any, and
    
county or counties of taxing district and geographic or other common name by which a school or community college district is known and referred to), Illinois, be authorized to levy a new tax for ... purposes and have an additional tax of ...% of the equalized assessed value of the taxable property therein extended for such purposes?
The votes must be recorded as "Yes" or "No".
    The proposition seeking to obtain referendum approval to increase the limiting rate as authorized in clause (ii) shall be in substantially the following form:
        Shall the limiting rate under the Property Tax
    
Extension Limitation Law for ... (insert legal name, number, if any, and county or counties of taxing district and geographic or other common name by which a school or community college district is known and referred to), Illinois, be increased by an additional amount equal to ...% above the limiting rate for the purpose of...(insert purpose) for levy year ... (insert the most recent levy year for which the limiting rate of the taxing district is known at the time the submission of the proposition is initiated by the taxing district) and be equal to ...% of the equalized assessed value of the taxable property therein for levy year(s) (insert each levy year for which the increase will be applicable, which years must be consecutive and may not exceed 4)?
    The votes must be recorded as "Yes" or "No".
    The ballot for any proposition submitted pursuant to this Section shall have printed thereon, but not as a part of the proposition submitted, only the following supplemental information (which shall be supplied to the election authority by the taxing district) in substantially the following form:
        (1) The approximate amount of taxes extendable at the
    
most recently extended limiting rate is $..., and the approximate amount of taxes extendable if the proposition is approved is $....
        (2) For the ... (insert the first levy year for which
    
the new rate or increased limiting rate will be applicable) levy year the approximate amount of the additional tax extendable against property containing a single family residence and having a fair market value at the time of the referendum of $100,000 is estimated to be $....
        (3) Based upon an average annual percentage increase
    
(or decrease) in the market value of such property of %... (insert percentage equal to the average annual percentage increase or decrease for the prior 3 levy years, at the time the submission of the proposition is initiated by the taxing district, in the amount of (A) the equalized assessed value of the taxable property in the taxing district less (B) the new property included in the equalized assessed value), the approximate amount of the additional tax extendable against such property for the ... levy year is estimated to be $... and for the ... levy year is estimated to be $ ....
        (4) If the proposition is approved, the aggregate
    
extension for ... (insert each levy year for which the increase will apply) will be determined by the limiting rate set forth in the proposition, rather than the otherwise applicable limiting rate calculated under the provisions of the Property Tax Extension Limitation Law (commonly known as the Property Tax Cap Law).
The approximate amount of taxes extendable shown in paragraph (1) shall be computed upon the last known equalized assessed value of taxable property in the taxing district (at the time the submission of the proposition is initiated by the taxing district). Paragraph (3) shall be included only if the increased limiting rate will be applicable for more than one levy year and shall list each levy year for which the increased limiting rate will be applicable. The additional tax shown for each levy year shall be the approximate dollar amount of the increase over the amount of the most recently completed extension at the time the submission of the proposition is initiated by the taxing district. The approximate amount of the additional taxes extendable shown in paragraphs (2) and (3) shall be calculated by multiplying $100,000 (the fair market value of the property without regard to any property tax exemptions) by (i) the percentage level of assessment prescribed for that property by statute, or by ordinance of the county board in counties that classify property for purposes of taxation in accordance with Section 4 of Article IX of the Illinois Constitution; (ii) the most recent final equalization factor certified to the county clerk by the Department of Revenue at the time the taxing district initiates the submission of the proposition to the electors; and (iii) either the new rate or the amount by which the limiting rate is to be increased. This amendatory Act of the 97th General Assembly is intended to clarify the existing requirements of this Section, and shall not be construed to validate any prior non-compliant referendum language. Paragraph (4) shall be included if the proposition concerns a limiting rate increase but shall not be included if the proposition concerns a new rate. Any notice required to be published in connection with the submission of the proposition shall also contain this supplemental information and shall not contain any other supplemental information regarding the proposition. Any error, miscalculation, or inaccuracy in computing any amount set forth on the ballot and in the notice that is not deliberate shall not invalidate or affect the validity of any proposition approved. Notice of the referendum shall be published and posted as otherwise required by law, and the submission of the proposition shall be initiated as provided by law.
    If a majority of all ballots cast on the proposition are in favor of the proposition, the following provisions shall be applicable to the extension of taxes for the taxing district:
        (A) a new tax rate shall be first effective for the
    
levy year in which the new rate is approved;
        (B) if the proposition provides for a new tax rate,
    
the taxing district is authorized to levy a tax after the canvass of the results of the referendum by the election authority for the purposes for which the tax is authorized;
        (C) a limiting rate increase shall be first effective
    
for the levy year in which the limiting rate increase is approved, provided that the taxing district may elect to have a limiting rate increase be effective for the levy year prior to the levy year in which the limiting rate increase is approved unless the extension of taxes for the prior levy year occurs 30 days or less after the canvass of the results of the referendum by the election authority in any county in which the taxing district is located;
        (D) in order for the limiting rate increase to be
    
first effective for the levy year prior to the levy year of the referendum, the taxing district must certify its election to have the limiting rate increase be effective for the prior levy year to the clerk of each county in which the taxing district is located not more than 2 days after the date the results of the referendum are canvassed by the election authority; and
        (E) if the proposition provides for a limiting rate
    
increase, the increase may be effective regardless of whether the proposition is approved before or after the taxing district adopts or files its levy for any levy year.
    Rates required to extend taxes on levies subject to a backdoor referendum in each year there is a levy are not new rates or rate increases under this Section if a levy has been made for the fund in one or more of the preceding 3 levy years. Changes made by this amendatory Act of 1997 to this Section in reference to rates required to extend taxes on levies subject to a backdoor referendum in each year there is a levy are declarative of existing law and not a new enactment.
    (b) Whenever other applicable law authorizes a taxing district subject to the limitation with respect to its aggregate extension provided for in this Law to issue bonds or other obligations either without referendum or subject to backdoor referendum, the taxing district may elect for each separate bond issuance to submit the question of the issuance of the bonds or obligations directly to the voters of the taxing district, and if the referendum passes the taxing district is not required to comply with any backdoor referendum procedures or requirements set forth in the other applicable law. The direct referendum shall be initiated by ordinance or resolution of the governing body of the taxing district, and the question shall be certified to the proper election authorities in accordance with the provisions of the Election Code.

    (35 ILCS 200/18-190.7)
    Sec. 18-190.7. Alternative aggregate extension base for certain taxing districts; recapture.
    (a) This Section applies to the following taxing districts that are subject to this Division 5:
        (1) school districts that have a designation of
    
recognition or review according to the State Board of Education's School District Financial Profile System as of the first day of the levy year for which the taxing district seeks to increase its aggregate extension under this Section;
        (2) park districts;
        (3) library districts; and
        (4) community college districts.
    (b) Subject to the limitations of subsection (c), beginning in levy year 2022, a taxing district specified in subsection (a) may recapture certain levy amounts that are otherwise unavailable to the taxing district as a result of the taxing district not extending the maximum amount permitted under this Division 5 in a previous levy year. For that purpose, the taxing district's aggregate extension base shall be the greater of: (1) the taxing district's aggregate extension limit; or (2) the taxing district's last preceding aggregate extension, as adjusted under Sections 18-135, 18-215, 18-230, 18-206, and 18-233.
    (c) Notwithstanding the provisions of this Section, the aggregate extension of a taxing district that uses an aggregate extension limit under this Section for a particular levy year may not exceed the taxing district's aggregate extension for the immediately preceding levy year by more than 5% unless the increase is approved by the voters under Section 18-205; however, if a taxing district is unable to recapture the entire unrealized levy amount in a single levy year due to the limitations of this subsection (c), the taxing district may increase its aggregate extension in each immediately succeeding levy year until the entire levy amount is recaptured, except that the increase in each succeeding levy year may not exceed the greater of (i) 5% or (ii) the increase approved by the voters under Section 18-205.
    In order to be eligible for recapture under this Section, the taxing district must certify to the county clerk that the taxing district did not extend the maximum amount permitted under this Division 5 for a particular levy year. That certification must be made not more than 60 days after the taxing district files its levy ordinance or resolution with the county clerk for the levy year for which the taxing district did not extend the maximum amount permitted under this Division 5.
    (d) As used in this Section, "aggregate extension limit" means the taxing district's last preceding aggregate extension if the district had utilized the maximum limiting rate permitted without referendum for each of the 3 immediately preceding levy years, as adjusted under Sections 18-135, 18-215, 18-230, 18-206, and 18-233.
