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.

    "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.

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, and 18-206. 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.
    "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 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 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 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 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 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.
