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
soon after they become law. For information concerning the relationship between statutes and Public Acts, refer to the
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 200/17-5)
Equalization among counties.
The Department shall act as an
equalizing authority. It shall examine the abstracts of property assessed for
taxation in the counties and in the assessment districts in counties having
assessment districts, as returned by the county clerks, and shall equalize the
assessments between counties as provided in this Code. Except as hereinafter
provided, the Department shall lower or raise the total assessed value of
property in each county as returned by the county clerk, other than
assessed under Sections 10-110 through 10-140 and 10-170 through 10-200, so
that the property will be assessed at 33 1/3% of its fair cash value.
The Department shall annually determine the percentage relationship, for each
county of the State, between the valuations at which locally-assessed property,
other than property assessed under the Sections 10-110 through 10-140 and
10-170 through 10-200, as listed by assessors and revised by boards
of review, and the estimated 33 1/3% of the fair cash value of
property. To make this analysis, the Department shall use property transfers,
property appraisals, and other means as it deems proper and reasonable.
With the ratio determined for each county, the Department shall then
determine the percentage to be added to or deducted from the aggregate reviewed
assessment on property subject to local assessment jurisdiction, other than
property assessed under the Sections cited above, to produce a ratio of
assessed value to 33 1/3% of the fair cash value equivalent to 100%.
