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.

Payment under protest.
Beginning with the 1994 tax year in
counties with 3,000,000 or more inhabitants, and beginning with the 1995 tax
year in all other counties, if
any person desires to object to all or any part of a property tax for any year,
reason other than that the property is exempt from taxation, he or she shall
pay all of the tax due
within 60 days from the first penalty date of the final installment of taxes
for that year. Whenever taxes are paid in compliance with this Section and a
tax objection complaint is filed in compliance with Section 23-10, 100% of the
taxes shall be deemed paid under protest without the filing of a separate
letter of protest with the county collector.

Tax objections and copies.
Beginning with the 2003
tax year, in
counties with 3,000,000 or more inhabitants, the person paying the taxes due
as provided in Section 23-5 may file
complaint under Section 23-15 within 165 days after the first
date of the final installment of taxes for the year in question.

inhabitants, the person paying the taxes
due as provided in Section 23-5 may file a tax objection complaint under
Section 23-15 within 75 days after the first penalty date of the final
installment of taxes for the year in question.
However, in all counties in cases in which the complaint is permitted to be
payment under Section 23-5, it must be filed prior to the entry of judgment
under Section 21-175. In addition, the time specified for payment of the tax
provided in Section 23-5 shall not be construed to delay or prevent the entry
of judgment against, or the sale of, tax delinquent property if the taxes have
not been paid prior to the entry of judgment under Section 21-175.
An objection to an assessment for any year shall not be
allowed by the court, however, if an administrative remedy was available by
complaint to the board of appeals or board of review under Section 16-55 or
Section 16-115, unless that remedy was exhausted prior to the filing of the tax
When any complaint is filed with the court in a
with less than
3,000,000 inhabitants, the plaintiff shall
file 3 copies of
the complaint with the clerk of the circuit court. Any
thereto shall contain (i) on the first page a listing of the taxing
against which the complaint is directed
and (ii) a summary of the
for the tax
forth in the complaint with enough copies of the summary to be distributed to
each of the
taxing districts against which the complaint is directed.
Within 10 days after
the complaint is
filed, the clerk of the circuit court shall deliver one copy to the State's
Attorney and one copy to the county clerk, taking their receipts therefor. The
county clerk shall, within 30 days from the last day for the filing of
complaints, notify the duly elected or appointed custodian
of funds for each
taxing district that may be affected by the complaint,
stating (i) that a complaint has been filed and (ii) the
summary of the reasons for the tax objections set forth in the complaint.
Any amendment to a
except any amendment
permitted to be made in open court during the course of a hearing on the
complaint, shall also be filed in triplicate, with one copy
delivered to the
State's Attorney and one copy delivered to the county clerk by the clerk of the
circuit court. The State's Attorney shall within 10 days of receiving his or
her copy of the amendment notify the duly elected or appointed custodian of
funds for each taxing district whose tax monies may be affected by the
amendment, stating (i) that the amendment has been filed and (ii) the
summary of the reasons for the tax objections set forth in the amended
The State's Attorney shall also notify the custodian and the county
clerk in writing of the date, time and place of any hearing before the court to
be held upon the complaint or amended complaint not later than 4 days prior to
the hearing. The notices provided in this Section shall
be by letter addressed to the custodian or the county clerk and may be
mailed by regular mail, postage prepaid, postmarked within the required period,
but not less than 4 days before a hearing.

(35 ILCS 200/23-15)
Tax objection procedure and hearing.
(a) A tax objection complaint under Section 23-10 shall be filed in the
circuit court of the county in which the subject property is located.
Joinder of plaintiffs shall be permitted to the same extent permitted by law in
any personal action pending in the court and shall be in accordance with
Section 2-404 of the Code of Civil
however, that no complaint shall be filed as a class action. The
complaint shall name the county collector as defendant and shall specify any
objections that the plaintiff may have to the taxes in question. No appearance
or answer by the county collector to the tax objection complaint, nor any
further pleadings, need be filed. Amendments to the complaint may be made to
the same extent which, by law, could be made in any personal action pending in
(b) (1) The court, sitting without a jury, shall hear and determine all
objections specified to the taxes, assessments, or levies in question. This
Section shall be construed to provide a complete remedy for any claims with
respect to those taxes, assessments, or levies, excepting only matters for
which an exclusive remedy is provided elsewhere in this Code.
(2) The taxes, assessments, and levies that are the subject of the objection
shall be presumed correct and legal, but the presumption is rebuttable.
The plaintiff has the burden of proving any contested matter of fact by
clear and convincing evidence.
(3) Objections to assessments shall be heard de novo by the court. The
court shall grant relief in the cases in which the objector meets the burden of
proof under this Section and shows an assessment to be incorrect or illegal.
If an objection is made claiming incorrect valuation, the court shall
consider the objection without regard to the correctness of any practice,
procedure, or method of valuation followed by the assessor, board of appeals,
or board of review in making or reviewing the assessment, and without regard
to the intent or motivation of any assessing official. The doctrine known
as constructive fraud is hereby abolished for purposes of all challenges to
taxes, assessments, or levies.
(c) If the court orders a refund of any part of the taxes paid, it shall
also order the payment of interest as provided in Section 23-20. Appeals may be
taken from final judgments as in other civil cases.
(d) This amendatory Act of 1995 shall apply to all tax objection matters
still pending for any tax year, except as provided in Sections 23-5 and 23-10
regarding procedures and time limitations for payment of taxes and filing tax
(e) In counties with less than 3,000,000 inhabitants, if the court
renders a decision lowering the assessment of a particular parcel on which a
residence occupied by the owner is situated, the reduced assessment, subject to
equalization, shall remain in effect for the remainder of the general
assessment period as provided in Sections 9-215 through 9-225, unless that
parcel is subsequently sold in an arm's length transaction establishing a fair
cash value for the parcel that is different from the fair cash value on which
the court's assessment is based, or unless the decision of the
court is reversed or modified upon review.

Effect of protested payments; refunds.
No protest shall
prevent or be a cause of delay in the distribution of
tax collections to the taxing districts of any taxes collected which were
not paid under protest.
If the final order of the Property Tax Appeal Board or of a court results
in a refund to the taxpayer, refunds shall be made by the collector from
remaining in the Protest Fund until such funds are exhausted and
thereafter from the next funds collected after entry of the final order until
full payment of the refund and interest thereon has been made. Interest from the date of payment, regardless of whether the
payment was made before the effective date of
amendatory Act of 1997, or from the date payment is due,
later, to the date of refund shall also be paid
the taxpayer at the annual rate of the lesser of (i) 5% or (ii) the percentage increase in the Consumer Price Index For All Urban Consumers during the 12-month calendar year preceding the levy year for which the refund was made, as published by the federal Bureau of Labor Statistics.

Tax exempt property; restriction on judicial determinations.
(a) No taxpayer
may file an objection as
provided in Section 21-175 or Section 23-10 on the grounds that the
property is exempt from
taxation, or otherwise seek a judicial determination as to tax exempt status,
except as provided in Section 8-40 and except as otherwise provided in this
Section and Section 14-25 and Section 21-175.
(b) Nothing in this Section shall
affect the right of a governmental agency to seek a judicial determination as
to the exempt status of property for those years during which eminent domain
proceedings were pending before a court, once a certificate of exemption for
the property is obtained by the governmental agency under Section 8-35 or
(c) This Section shall not apply to exemptions granted under Sections
(d) The limitation in this Section shall not apply to court proceedings
relating to an exemption for the 1985 assessment year and preceding assessment
years. However, an order entered in any such proceeding shall not preclude the
necessity of applying for an exemption for 1986 or later assessment years in
the manner provided by Section 16-70 or 16-130.
(e) The limitation in this Section shall not apply to court proceedings to
establish an exemption for any specific assessment year, provided that the
plaintiff or its predecessor in interest in the property has established an
exemption for any subsequent or prior assessment year on grounds comparable to
those alleged in the court proceedings. For purposes of this subsection, the
exemption for a subsequent or prior year must have been determined under
Section 8-35 or a prior similar law by the Department or a predecessor agency,
or under Section 8-40. Court proceedings permitted by this subsection may be
initiated while proceedings for the subsequent or prior year under Section
16-70, 16-130, 8-35, or 8-40 are still pending, but judgment shall not be
entered until the proceedings under Section 8-35 or 8-40 have terminated.

Tax objection based on budget or appropriation ordinance.
Notwithstanding the provisions of Section 23-10, no objection to
tax levied by any municipality shall be sustained by any court because of the
forms of any budget or appropriation ordinance, or the degree of itemization or
classification of items therein, or the reasonableness of any amount budgeted
or appropriated thereby, if:
(a) a tentative budget and appropriation ordinance
was prepared at the direction of the governing body of the municipality and made conveniently available to public inspection for at least 30 days prior to the public hearing specified below and to final action thereon;
(b) at least one public hearing has been held by the
governing body as to the tentative budget and appropriation ordinance prior to final action thereon, and notice of the time and place where copies of the tentative budget and appropriation ordinances are available for public inspection, and the time and place of the hearing, has been given by publication in a newspaper published in the municipality at least 30 days prior to the time of the hearing, or, if there is no newspaper published in the municipality, notice of the public hearing has been given by publication in a newspaper of general circulation in the municipality; and
(c) the budget and appropriation ordinance finally
adopted is substantially identical, as to the matters to which objection is made, with the tentative budget and appropriation ordinance submitted at the public hearing, unless the taxpayer making the objection has made the same objection in writing and with the same specificity to the governing body of the municipality prior to the adoption of the budget and appropriation ordinance.

Error or informality in making levy or in certifying or filing.
In all judicial proceedings concerning the levying and collection of taxes, an
error or informality of any officer or officers in making any tax levy or in
certifying or filing the levy not affecting the substantial justice of the levy
itself, shall not vitiate or void the levy or affect the tax. When the error
or informality in a levy, its certification, filing or publication can be
corrected by amendment, or a levy can be sufficiently itemized, the purpose
defined and made certain by amendment, made prior to the entry of any order of
court affecting the levy or the collection of taxes thereon, an amendment or
amendments, certification, filing or publication may be made by the taxing
bodies affected. The ordinance, resolution, publication or certificate, as
amended, certified, filed or published, shall, upon proof of such amendment or
amendments, certification, filing or publication being made to the court, have
the same force and effect as though originally adopted, published, filed and
certified in the amended form. The aggregate amount or rate of the original
levy shall not be increased by an action taken under this Section. A statute
terminating the time within which appropriations or tax levies may be made,
published, certified or filed, shall not apply to any republication,
recertification or refiling, or to any amendment or revision authorized or
permitted by this Section.

date an objection is filed there has been no further action on the objection,
the objection shall be dismissed as a matter of law with prejudice. The
circuit clerk shall enter the dismissal of record. The Collector may then
distribute the taxes. The Collector shall determine whether to use the tax
rates for the year the objection was filed or the tax rates for the most recent
tax year in distributing the taxes. This Section applies to tax objections
filed before, on, or after the effective date of this amendatory Act of
