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.

    (35 ILCS 200/21-5)
    Sec. 21-5. Forfeiture tax extension records; counties of 3,000,000 or more. In counties with 3,000,000 or more inhabitants, the county clerk shall quadrennially or at regular intervals prescribed by county resolution under Section 9-220 prepare a set of records to be known as the county clerk's forfeiture tax extension records, showing in separate columns and items the legal description of all property which has previously been forfeited for the non-payment of general taxes, the amount of the forfeited taxes of prior years, the interest added before forfeiture, the interest added after forfeiture, and all printers' fees and costs chargeable against each property. The records shall also show in proper spaces all annual new and additional amounts of forfeited general taxes, interest added before forfeiture, interest added after forfeiture, and all printers' fees and costs chargeable against the properties which become so chargeable during the years following the general assessment year. The records are to remain at all times at the county clerk's office for use in preparing estimates of costs of redemption and in issuing orders upon the county collector to receive amounts necessary for the redemption of forfeited general taxes. Nothing in this section shall be construed as abolishing or interfering in any way with the collector's tax books, the tax judgment, sale, redemption and forfeiture records or any other records or books provided for in this Code.

    (35 ILCS 200/21-10)
    Sec. 21-10. Delinquent tax ledger; counties of 3,000,000 or more. In counties with 3,000,000 or more inhabitants, the county board may by resolution or ordinance require the County Auditor to prepare a delinquent property tax ledger system, or adopt such a system already prepared and give custody of the same to the County Auditor, in which all the delinquent taxes due upon the various properties in the county shall be listed under the legal description of each property provided that the resolution or ordinance of the county board in adopting the system shall provide that a Delinquent Property Tax Ledger shall be installed and maintained by the County Auditor. The ledger shall contain all unpaid general property taxes. The resolution or ordinance shall also provide that a Property Tax Docket shall be installed and maintained by the County Clerk. The docket shall contain and list all court proceedings which affect the general property taxes levied upon any property. The Property Tax Docket and the Property Tax Ledger shall be installed by the respective County Officers within 60 days from the date of the adoption of the ordinance or resolution by the county board. The ordinance or resolution shall prescribe the form and manner of maintenance of the system, which system may also include such other related matters as the ordinance or resolution requires. The ordinance or resolution may also provide for a similar system for delinquent special assessments in the office of the County Clerk. Upon the adoption of such a system by the county board, the County Clerk upon application shall issue a certificate stating the total amount of general taxes, special assessment taxes, interest, penalties and costs which are delinquent upon any property, or if none is delinquent, a statement to that effect. The certificate as issued by the County Clerk may contain such additional information as the resolution or ordinance of the county board adopting such a system requires. That part of the certificate issued by the County Clerk showing the amount of delinquent general property taxes due upon any property shall be certified to by the County Auditor or if none is delinquent, a certification by the County Auditor to that effect. The county board may provide a fee not to exceed $5 for each certificate to be paid to the County Clerk and shall provide that a portion of the fee shall be placed in an indemnity fund in the custody of the County Treasurer to indemnify any person, municipal corporation, quasi-municipal or district which may be damaged by reason of any erroneous certificate.

    Sec. 21-15. General tax due dates; default by mortgage lender. Except as otherwise provided in this Section or Section 21-40, all property upon which the first installment of taxes remains unpaid on the later of (i) June 1 or (ii) the day after the date specified on the real estate tax bill as the first installment due date annually shall be deemed delinquent and shall bear interest after that date. For property located in a county with fewer than 3,000,000 inhabitants, the unpaid taxes shall bear interest at the rate of 1 1/2% per month or portion thereof. For property located in a county with 3,000,000 or more inhabitants, the unpaid taxes shall bear interest at the rate of (i) 1.5% per month, or portion thereof, if the unpaid taxes are for a tax year before 2023 or (ii) 0.75% per month, or portion thereof, if the unpaid taxes are for tax year 2023 or any tax year thereafter. Except as otherwise provided in this Section or Section 21-40, all property upon which the second installment of taxes remains due and unpaid on the later of (i) September 1 or (ii) the day after the date specified on the real estate tax bill as the second installment due date, annually, shall be deemed delinquent and shall bear interest after that date at the same interest rate. Notwithstanding any other provision of law, in counties with fewer than 3,000,000 inhabitants, if a taxpayer owes an arrearage of taxes due to an administrative error, and if the county collector sends a separate bill for that arrearage as provided in Section 14-41, then any part of the arrearage of taxes that remains unpaid on the day after the due date specified on that tax bill shall be deemed delinquent and shall bear interest after that date at the rate of 1 1/2% per month or portion thereof. Notwithstanding any other provision of law, in counties with 3,000,000 or more inhabitants, if a taxpayer owes an arrearage of taxes due to an administrative error, and if the county collector sends a separate bill for that arrearage as provided in Section 14-41, then any part of the arrearage of taxes that remains unpaid on the day after the due date specified on that tax bill shall be deemed delinquent and shall bear interest after that date at the rate of (i) 1 1/2% per month, or portion thereof, if the arrearage is for a tax year before tax year 2023 or (ii) 0.75% per month, or portion thereof, if the arrearage is for tax year 2023 or any tax year thereafter. All interest collected shall be paid into the general fund of the county. Payment received by mail and postmarked on or before the required due date is not delinquent.
    Property not subject to the interest charge in Section 9-260 or Section 9-265 shall also not be subject to the interest charge imposed by this Section until such time as the owner of the property receives actual notice of and is billed for the principal amount of back taxes due and owing.
    If an Illinois resident who is a member of the Illinois National Guard or a reserve component of the armed forces of the United States and who has an ownership interest in property taxed under this Act is called to active duty for deployment outside the continental United States and is on active duty on the due date of any installment of taxes due under this Act, he or she shall not be deemed delinquent in the payment of the installment and no interest shall accrue or be charged as a penalty on the installment until 180 days after that member returns from active duty. To be deemed not delinquent in the payment of an installment of taxes and any interest on that installment, the reservist or guardsperson must make a reasonable effort to notify the county clerk and the county collector of his or her activation to active duty and must notify the county clerk and the county collector within 180 days after his or her deactivation and provide verification of the date of his or her deactivation. An installment of property taxes on the property of any reservist or guardsperson who fails to provide timely notice and verification of deactivation to the county clerk is subject to interest and penalties as delinquent taxes under this Code from the date of deactivation.
    Notwithstanding any other provision of law, when any unpaid taxes become delinquent under this Section through the fault of the mortgage lender, (i) the interest assessed under this Section for delinquent taxes shall be charged against the mortgage lender and not the mortgagor and (ii) the mortgage lender shall pay the taxes, redeem the property and take all necessary steps to remove any liens accruing against the property because of the delinquency. In the event that more than one entity meets the definition of mortgage lender with respect to any mortgage, the interest shall be assessed against the mortgage lender responsible for servicing the mortgage. Unpaid taxes shall be deemed delinquent through the fault of the mortgage lender only if: (a) the mortgage lender has received all payments due the mortgage lender for the property being taxed under the written terms of the mortgage or promissory note secured by the mortgage, (b) the mortgage lender holds funds in escrow to pay the taxes, and (c) the funds are sufficient to pay the taxes after deducting all amounts reasonably anticipated to become due for all hazard insurance premiums and mortgage insurance premiums and any other assessments to be paid from the escrow under the terms of the mortgage. For purposes of this Section, an amount is reasonably anticipated to become due if it is payable within 12 months from the time of determining the sufficiency of funds held in escrow. Unpaid taxes shall not be deemed delinquent through the fault of the mortgage lender if the mortgage lender was directed in writing by the mortgagor not to pay the property taxes, or if the failure to pay the taxes when due resulted from inadequate or inaccurate parcel information provided by the mortgagor, a title or abstract company, or by the agency or unit of government assessing the tax.

The taxing district shall promptly notify the county supervisor of assessments upon the execution of a new lease or the termination of a lease for property owned by the taxing district. The State's Attorney of the county in which the property is located may bring an action against the lessee in the circuit court in the name of the People of the State of Illinois, and, upon proof of liability, the court shall enter judgment against the lessee in a sum equal to the full amount of delinquent taxes, interest, penalties, and costs. This judgment shall be enforceable against the lessee, or any other parties provided by applicable law, in any manner permitted by law for the collection of a debt or judgment. The proceeds of any judgment under this Section shall be distributed to the taxing districts as otherwise provided in this Code.

    Sec. 21-35. Estimated billing in overlapping districts. In counties with less than 3,000,000 inhabitants, when the certified assessed valuations for that portion of overlapping taxing districts lying in another county for the preceding year have not been received by the county clerk by March 1, the county board, upon petition of the county clerk, may by resolution or ordinance adopted on or prior to April 1 of that year, adopt the estimated property tax billing system provided for in this Section for taxes for the preceding year.

    (a) In any county with less than 3,000,000 inhabitants, the county board may adopt an ordinance under which 50% of each installment of taxes shall not become delinquent until 60 days after each installment would otherwise become delinquent under Sections 21-15, 21-20, 21-25 or 21-30.
    (b) Beginning with installments of taxes and special assessments payable in 1994, in any county that has been designated, in whole or in part, as a disaster area by the President of the United States or the Governor of the State of Illinois due to a disaster that occurred during the calendar year in which the taxes are payable or in the preceding calendar year, the county board may adopt an ordinance or resolution under which interest allowed to be assessed on special assessments or allowed to be assessed under Sections 21-15, 21-20, and 21-25 on delinquent installments of taxes for real property within one or more townships (or congressional townships if the assessor's books are organized by congressional townships) designated by the county board, that have been affected by the disaster does not accrue until the court enters the order for sale of the property. The ordinance or resolution shall provide that a person may pay a delinquent installment of taxes or special assessment without interest being assessed until the last working day before the court enters the order for sale of the property. If adopted, the ordinance or resolution must establish a procedure for affected property owners to make application to a designated county official who shall determine, according to the guidelines in the ordinance or resolution, whether the property is substantially damaged or adversely affected and shall approve damaged or adversely affected property for the delay in accrual of interest specified in the ordinance or resolution. The designated county official shall notify the county collector of the parcel number and the name of the owner of property approved for relief.
    (c) (1) The governing authority of any county that has been designated, in whole or in part, as a disaster area by the President of the United States or the Governor of the State of Illinois may adopt an ordinance or resolution modifying the provisions of this Act relating to any specified installment or installments of real property tax or special assessment on real property that is situated within the designated disaster area and that is determined, in the manner provided in the ordinance or resolution, to be substantially damaged or adversely affected as a result of that disaster.
    The ordinance or resolution may:
        (A) postpone the date on which any specified
    
installment or installments of tax due on that real property in the current year becomes or became delinquent under Section 21-15, 21-20, or 21-25;
        (B) exempt any specified installment or installments
    
of tax due on that real property from the interest penalty provided under Section 21-15, 21-20, or 21-25 until the postponed delinquency date established by the ordinance or resolution;
        (C) postpone the date on which a special assessment
    
due on that real property in the current year becomes or became delinquent; and exempt a special assessment due on that real property from any interest penalty until the postponed delinquency date established by the ordinance or resolution; and
        (D) order the county collector not to give notice of
    
application for judgment for sale under Section 21-110 or 21-120 and not to apply for judgment and order of sale under Section 21-150, until after the postponed delinquency date for the final installment of tax or special assessment due on that real property as established in the ordinance or resolution.
    (2) The ordinance or resolution shall establish a procedure for owners of real property situated in the designated disaster area to make application to a designated county official, who shall determine, within the guidelines established by the ordinance or resolution, if the property is substantially damaged or adversely affected and approve the property for relief as specified in the ordinance or resolution adopted under this subsection (c). The designated county official shall notify the county collector of the parcel number and name of the property owner of property approved for relief.
    (3) The ordinance or resolution may also direct the county collector to give a credit against a special assessment or the extension of the general corporate levy of the county for the year following the year in which the disaster is declared to the owner of property approved for relief in an amount equal to any interest penalty paid by that owner on any specified installment or installments of tax due on that property in the year the disaster is declared, if that interest penalty was paid before the ordinance or resolution was adopted or before the postponed delinquency dates.
    (4) The ordinance or resolution may also direct the county collector to refund any installment or installments, and any special assessment or interest penalties thereon, of tax due, in the year the disaster is declared, on property approved for relief, that have been paid by the holder of a certificate of purchase for a prior year on that property.

    Sec. 21-50. Annexations, disconnection or dissolution - Accelerated billing. In the event any property becomes newly liable for taxes levied by any taxing district because of an incorporation or annexation of the taxing district or liability does not exist because of a disconnection of any area of the unit of local government or school district or the dissolution thereof, each estimated installment of property taxes provided for in Section 21-30 shall be computed at 25% of the total of the tax bill for the property for the preceding year. Taxes for which the property becomes newly liable or for which liability does not exist for the property because of a disconnection of any area of, or the dissolution of, any taxing district, shall be added to or subtracted from the balance of taxes due for that year under Section 21-30.

    Sec. 21-55. Cancellation of accelerated tax bill. Any person may object to an estimated tax bill under Section 21-30 on forms provided by the county collector solely on the grounds that the estimate is based on (a) a tax bill pertaining to any property which was divided subsequent to the time for preparation of the collector's books in the year previous to the year the tax bill on which the estimate is based became delinquent, or (b) the property is no longer located within the corporate limits of any taxing district. Upon a finding by the county collector that the protest is factually correct and that tax bills for that property, or divisions thereof, have been or are being prepared and will be mailed as otherwise provided in this Code, the county collector shall mark the estimated bill and his or her books in an appropriate manner and so inform the county clerk and the estimated tax bill shall be cancelled. No payment of taxes shall be required prior to the filing of an objection permitted by this Section.
