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.

Division 5.1. One-year Property Tax Extension Limitation Law.

35 ILCS 200/18-246

    (35 ILCS 200/18-246)
    Sec. 18-246. Short title; definitions. This Division 5.1 may be cited as the One-year Property Tax Extension Limitation Law.
    As used in this Division 5.1:
    "Taxing district" has the same meaning provided in Section 1-150, except that it includes only each non-home rule taxing district with the majority of its 1993 equalized assessed value contained in one or more affected counties, as defined in Section 18-185, other than those taxing districts subject to the Property Tax Extension Limitation Law before February 12, 1995 (the effective date of Public Act 89-1).
    "Aggregate extension" 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; and (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.
    "Special purpose extensions" includes, but is not limited to, extensions for levies made on an annual basis for unemployment compensation, workers' compensation, self-insurance, contributions to pension plans, and extensions made under 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 aggregate extension for the 1993 levy year as adjusted under Section 18-248.
    "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 and (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.
    "Recovered tax increment value" means the amount of the 1994 equalized assessed value, in the first year after a city terminates the designation of an area as a redevelopment project area previously established under the Tax Increment Allocation Redevelopment Act of the Illinois Municipal Code or previously established under the Industrial Jobs Recovery Law of the Illinois Municipal Code, 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.
    Except as otherwise provided in this Section, "limiting rate" means a fraction the numerator of which is the aggregate extension base times 1.05 and the denominator of which is the 1994 equalized assessed value of all real property in the territory under the jurisdiction of the taxing district during the 1993 levy year. The denominator shall not include new property and shall not include the recovered tax increment value.

35 ILCS 200/18-247

    (35 ILCS 200/18-247)
    Sec. 18-247. Limitation. Tax extensions for the 1994 levy year made under Sections 18-45 and 18-105 are further limited by the provisions of this Law.
    For those taxing districts for which the county clerk extended taxes for any funds included in the aggregate extension base for the 1993 levy year, the county clerk shall extend a rate for the sum of the funds in the aggregate extension base that is no greater than the limiting rate.
    This limitation does not apply to those taxing districts for which the county clerk did not extend taxes for any funds included in the aggregate extension base for the 1993 levy year, except that it does apply to those districts that have an aggregate extension base established under subsection (a) of Section 18-248.
    If the county clerk is required to reduce the aggregate extension of a taxing district by provisions of this Law, the county clerk shall proportionally reduce the extension for each fund unless otherwise requested by the taxing district.
(Source: P.A. 89-1, eff. 2-12-95.)

35 ILCS 200/18-248

    (35 ILCS 200/18-248)
    Sec. 18-248. Adjustments to the limiting rate.
    (a) Merging and consolidating taxing districts. For purpose of this Law, when 2 or more taxing districts merge or consolidate, the sum of the last preceding aggregate extension for each taxing district shall be combined for the resulting merged or consolidated taxing district. When a service performed by one taxing district is transferred to another taxing district, that part of the aggregate extension base for that purpose shall be transferred and added to the aggregate extension base of the transferee taxing district for purposes of this Law and shall be deducted from the aggregate extension base of the transferor taxing district.
    (b) Annexed or disconnected property. If property is annexed into the taxing district or is disconnected from a taxing district during the current levy year, the calculation of the limiting rate under Section 18-246 is not affected. The rates as limited under this Law are applied to all property in the district for the 1994 levy year, excluding property that was annexed after the adoption of the levy for the current levy year.
    (c) Rate increase or decrease factor. When a new rate or a rate increase or decrease that is first effective for the 1994 levy year has been approved by referendum, the aggregate extension base, as adjusted in subsection (a), shall be multiplied by a rate increase or decrease factor. The numerator of the rate increase or decrease factor is the total combined rate for the funds that made up the aggregate extension for the taxing district for the 1993 levy year plus the rate increase approved or minus the rate decrease approved. The denominator of the rate increase or decrease factor is the total combined rate for the funds that made up the aggregate extension for the 1993 levy year. For those taxing districts for which a new rate or a rate increase has been approved by referendum held after December 31, 1989, and that did not increase their rate to the new maximum rate for that fund, the rate increase factor for the 1994 levy year shall be adjusted by a factor the numerator of which is the portion of the new or increased rate for which taxes were not extended plus the aggregate rate in effect for the levy year prior to the levy year in which the referendum was passed and the denominator of which is the aggregate rate in effect for the levy year prior to the levy year in which the referendum was passed.
    (d) Tax increment financing districts. Extensions allocable to a special tax allocation fund and the amount of taxes abated under Sections 18-165 and 18-170 are not included in the aggregate extension base when computing the limiting rate.

35 ILCS 200/18-249

    (35 ILCS 200/18-249)
    Sec. 18-249. Miscellaneous provisions.
    (a) Certification of new property. For the 1994 levy year, the chief county assessment officer shall certify to the county clerk, after all changes by the board of review or board of appeals, as the case may be, the assessed value of new property by taxing district for the 1994 levy year under rules promulgated by the Department.
    (b) School Code. A school district's State aid shall not be reduced under the computation under subsections 5(a) through 5(h) of Part A of Section 18-8 of the School Code or under Section 18-8.15 of the School Code due to the operating tax rate falling from above the minimum requirement of that Section of the School Code to below the minimum requirement of that Section of the School Code due to the operation of this Law.
    (c) Rules. The Department shall make and promulgate reasonable rules relating to the administration of the purposes and provisions of Sections 18-246 through 18-249 as may be necessary or appropriate.

Division 6. Preparation and delivery of books

35 ILCS 200/18-250

    (35 ILCS 200/18-250)
    Sec. 18-250. Additions to forfeited taxes and unpaid special assessments; fee for estimate.
    (a) When any property has been forfeited for taxes or special assessments, the clerk shall compute the amount of back taxes and special assessments, interest, statutory costs, and printer's fees remaining due, with one year's interest on all taxes forfeited, and enter them upon the collector's books as separate items. Except as otherwise provided in Section 21-375, the aggregate so computed shall be collected in the same manner as the taxes on other property for that year. The county clerk shall examine the forfeitures, and strike all errors and make corrections as necessary. Interest added to forfeitures under this Section shall be at the rate of 12% per year.
    (b) In counties with 3,000,000 or more inhabitants, taxes first extended for prior years, or previously extended for prior years for which application for judgment and order of sale is not already pending, shall be added to the tax of the current year, with interest and costs as provided by law. Forfeitures shall not be so added, but they shall remain a lien on the property upon which they were charged until paid or sold as provided by law. There shall be added to such forfeitures annually the same interest as would be added if forfeited annually, until paid or sold, and the addition of each year's interest shall be considered a separate forfeiture. Forfeitures may be redeemed in the manner provided in Section 21-370 or 21-375. Taxes and special assessments for which application for judgment and order of sale is pending, or entered but not enforced for any reason, shall not be added to the tax for the current year. However, if the taxes and special assessments remain unpaid, the property, shall be advertised and sold under judgments and orders of sale to be entered in pending applications, or already entered in prior applications, including judgments and orders of sale under which the purchaser fails to complete his or her purchase.
    (c) In counties with 3,000,000 or more inhabitants, on or before January 1, 2001 and during each year thereafter, the county clerk shall compute the amount of taxes on each property that remain due or forfeited for any year prior to the current year and have not become subject to Sections 20-180 through 20-190, and the clerk shall enter the same upon the collector's warrant books of the current and all following years as separate items in a suitable column. The county clerk shall examine the collector's warrant books and the Tax Judgment, Sale, Redemption and Forfeiture records for the appropriate years and may take any other actions as the clerk finds to be necessary or convenient in order to comply with this subsection. On and after January 1, 2001, any taxes for any year remaining due or forfeited against real property in such county not entered on the current collector's warrant books shall be deemed uncollectible and void, but shall not be subject to the posting or other requirements of Sections 20-180 through 20-190.
    (d) In counties with 100,000 or more inhabitants, the county clerk shall, when making the annual collector's books, in a suitable column, insert and designate previous forfeitures of general taxes by the word "forfeiture", to be stamped opposite each property forfeited at the last previous tax sale for general taxes and not redeemed or purchased previous to the completion of the collector's books. The collectors of general taxes shall stamp upon all bills rendered and receipts given the information on the collector's books regarding forfeiture of general taxes, and the stamped notation shall also refer the recipient to the county clerk for full information. The county clerk shall be allowed to collect from the person requesting an estimate of costs of redemption of a forfeited property, the fee provided by law.

    (a) To insure that a person requesting a change of the address to which a property tax bill is sent has a legal interest in the property or authority to act on behalf of the owner of the property, the county collector in every county with less than 3,000,000 inhabitants or less shall establish and enforce a procedure for requiring identification or certification of the identity of taxpayers who request a change in the address to which their tax bill is mailed.

However, if a property owner conveys a permanent change of address in writing to the United States Postal Service, then, on or after the effective date of that change of address, the county collector may mail a property tax bill to the property owner at his or her new address regardless of whether or not the owner notifies the collector of the address change.
    (b) As an alternative to mailing a copy of the bill, the collector may send the tax bill via e-mail at the request of the taxpayer, subject to the provisions of subsection (b) of Section 20-5 of this Act. If the taxpayer makes such a request, then the taxpayer shall notify the collector of any change in his or her e-mail address as soon as possible after the address is changed.

A county collector may refuse to accept a personal or corporate check within 45 days before a tax sale or at any time if a previous payment by the same payer was returned by a bank for any reason.
    (b) Beginning on January 1, 2012, subject to compliance with all applicable purchasing requirements, a county with a population of more than 3,000,000 is required to accept payment by credit card for each installment of property taxes; provided that all service charges or fees, as determined by the county, associated with the processing or accepting of a credit card payment by the county shall be paid by the taxpayer. If a taxpayer elects to make a property tax payment by credit card and a service charge or fee is imposed, the payment of that service charge or fee shall be deemed voluntary by the taxpayer and shall not be refundable. Nothing in this subsection requires a county with a population of more than 3,000,000 to accept payment by credit card for the payment on any installment of taxes that is delinquent under Section 21-10, 21-25, or 21-30 of the Property Tax Code or for the purposes of any tax sale or scavenger sale under Division 3.5, 4, or 5 of Article 21 of the Property Tax Code. A county that accepts payment of property taxes by credit card in accordance with the terms of this subsection shall not incur liability for or associated with the collection of a property tax payment by credit card. The public hearing requirement of subsection (a) of Section 20 of the Local Governmental Acceptance of Credit Cards Act shall not apply to this subsection. This subsection is a limitation under subsection (i) of Section 6 of Article VII of the Illinois Constitution on the concurrent exercise by home rule units of powers and functions exercised by the State.

If in any township the office of township collector is or becomes vacant, and the vacancy is not filled on or before the first day of May next following the vacancy, the county clerk shall deliver all the collectors' books to the county collector of the county, having annexed to each book a warrant under the signature and official seal of the county clerk, commanding the county collector to collect from the persons named in the books the sum of taxes charged opposite their names, except as otherwise provided in Section 21-375. The county collector shall then collect and pay over all taxes, assessments and other charges shown in the books, and do all acts required by law as if the taxes, assessments and other charges had been duly returned delinquent by a township collector. The collectors' books so delivered to the county collector shall, for all purposes, in all subsequent proceedings, be used in the same manner and have the same force and effect as if the books were delivered to the township collectors, and returned by them, as provided by law. In the 10 years next following the completion of a general reassessment of property in any county with 3,000,000 or more inhabitants, made under order of the Department, if for any reason the books have not been delivered to the township collector within 5 days after the day specified by the county clerk for that delivery, the county clerk shall deliver the books to the county collector, and all provisions of this Section shall apply. When any injunction restraining the collection of taxes is dissolved after the tax books are returned to the county collector, the taxes or the portion thereof upon which the injunction has been dissolved, shall be paid to the county collector, who shall proceed as though collection of the taxes had never been enjoined.

However, the penalties provided by law shall attach to the special assessments, special taxes, or installments thereof, and interest, in the same manner as if there were only one judgment and order of sale. County collectors shall collect, account for, and pay over the special assessments, special taxes, or installments to the authorities or persons having authority to receive them, in the same manner as they are required to collect, account for, and pay over taxes.
    Upon return of delinquent special assessments to the county collector, he or she may transfer the amounts stated on the returns to the tax books, setting down opposite the respective properties, in proper columns, the amounts assessed against each property.

    Sec. 20-110. Prior year's taxes to be added to current taxes. The amount due for general taxes on property previously forfeited to the State or otherwise remaining unpaid prior to the issuance of the collector's warrant, shall, except as otherwise provided in Section 18-250, be added to the tax of the current year; and the amount thereof shall be charged to the county collector with the amount of taxes for the current year. The amount so charged shall be placed on the tax books, and, except as otherwise provided in Section 21-375, shall be collected and paid over in like manner as other taxes. The county collector is authorized to advertise and sell the property in the manner required by this Code, as if said property had never been forfeited to the State. The county, city, village, incorporated town or school district may, by their agent attend the sale for taxes and buy the property and acquire the same rights that individuals now have under the law, and acquire, hold, sell and dispose of title thereto, the same as and in the same manner as individuals may do under the laws of this State, in case of sale for taxes. The additions and sales shall be continued from year to year until the taxes on the property are paid, by sale or otherwise.
