A debt service extension base established or increased at any
time pursuant to any provision of this Law, except Section
18-212, shall be increased each year commencing with the later
of (i) the 2009 levy year or (ii) the first levy year in which
this Law becomes applicable to the taxing district, by the
lesser of 5% or the percentage increase in the Consumer Price

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.
Whenever an adjustment is required under Section 18-233, 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
the actual valuations and rates, as adjusted for the increases
or reductions specified in Section 18-233, had been used to
calculate the extension of taxes for the levy year in which the
overextension or underextension occurred.
Notwithstanding any other provision of law, for levy year

SB0508 - 15 - LRB102 04495 HLH 14514 b

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

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,

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 Development 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

SB0508 - 17 - LRB102 04495 HLH 14514 b
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 Development 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 Development 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

SB0508 - 18 - LRB102 04495 HLH 14514 b
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

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.

Sec. 18-233. Adjustments for certificates of error,
decisions of the board of review, or decisions of the Property
Tax Appeal Board. Beginning in levy year 2021, a taxing
district's aggregate extension base shall be adjusted whenever
an assessment increase or decrease due to the issuance of a
certificate of error, a decision of the board of review, or a
decision of the Property Tax Appeal Board results in the
overextension or underextension of taxes for the last
preceding levy year. Whenever an adjustment is required under
this Section, 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 the actual valuations and rates, as
adjusted for the increases or reductions specified in this

SB0508 - 20 - LRB102 04495 HLH 14514 b
Section, had been used to calculate the extension of taxes for
the levy year in which the overextension or underextension
occurred.
Section 99. Effective date. This Act takes effect upon
