    AN ACT concerning revenue.
 
    Be it enacted by the People of the State of Illinois, 
represented in the General Assembly:
 
    Section 5. The Property Tax Code is amended by changing 
Section 18-185 as follows:
 
    (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

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

more inhabitants. 
    "Taxing district" has the same meaning provided in Section 
1-150, except as otherwise provided in this Section. For the

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

of subsection (e) of Section 18-213 for the 1996 levy year, 
constituting an extension for payment of principal and 
interest on bonds issued by the taxing district without

For park districts (i) that were first subject to this Law in

for the payment of principal and interest on bonds issued by 
the park district without referendum (but not including 
excluded non-referendum bonds) was less than 51% of the amount 
for the 1991 levy year constituting an extension for payment 
of principal and interest on bonds issued by the park district

referendum (but not including excluded non-referendum bonds). 
A debt service extension base established or increased at any

this Law becomes applicable to the taxing district, by the

    "Special purpose extensions" include, but are not limited 
to, extensions for levies made on an annual basis for 
unemployment and workers' compensation, self-insurance, 
contributions to pension plans, and extensions made pursuant 
to Section 6-601 of the Illinois Highway Code for a road 
district's permanent road fund whether levied annually or not. 
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 the 
purpose of calculating the limiting rate for levy year 2023, 
the last preceding aggregate extension base for Homewood 
School District No.
 153 in Cook County shall be $19,535,377. 
    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.
