What the figures are
This page reproduces the Department of Revenue's average tax rate for each county from Table 8 of its 2024 property tax statistics: taxes extended as a percent of equalized assessed value (EAV), in total and by class of property. IDOR does not print the unit; its Table 1 gives 2024 taxes extended and EAV, and dividing one by the other matches Table 8 to within six thousandths of a point (statewide $40,372,486,755 ÷ $511,341,383,351 = 7.895%, printed 7.89). A county average blends many taxing districts, so it is not the rate on any one bill. Period: tax year 2024 (taxes payable in 2025), from the Department of Revenue's Property Tax Statistics for 2024 (Table 8, published January 2026).
Footnote (1. "includes tax increment financing." (Table 8)
Footnote *. "includes enterprise zone abatements." (Table 8)
- The rate applies to equalized assessed value, not market value; the share of market value that is assessed was not read from an official source for this page, so no example bill is given.
- The table prints the footnote marks beside the commercial column: 98 of the 102 counties carry (1 (of which 52 also carry *) and 4 carry none. The spreadsheet shows two decimals for the totals; the class columns are stored unrounded and shown here to two decimals.
- IDOR also prints regional rows for 2024: Cook County 8.13%, Collar Counties 7.64%, Rest of State 7.74%.

How to appeal an assessment in Illinois
- Contest the assessment before the county board of review: by the board of review's own filing deadline, which the Property Tax Appeal Board's rule refers to but does not state.
- Petition the Property Tax Appeal Board: in counties with fewer than 3,000,000 inhabitants, within 30 days after the date of the written notice of the board of review's decision; in counties with 3,000,000 or more inhabitants, within 30 days after the later of that date and the date the board of review transmits its final action on the township to the county assessor.

Questions
What is the property tax rate in Illinois?
Illinois publishes no single rate. This page reproduces the Department of Revenue's average tax rate for each county from Table 8 of its 2024 property tax statistics: taxes extended as a percent of equalized assessed value (EAV), in total and by class of property. For 2024 it runs from 4.48% of EAV in Hardin County to 9.65% of EAV in Jackson County; the median county is 7.36% of EAV.
Which Illinois county has the highest average tax rate?
Jackson County, at 9.65% of EAV, among the 102 counties ranked here; Hardin County is lowest at 4.48% of EAV. These are county figures, so a single property's rate can be higher or lower.
Is the average tax rate the rate on my tax bill?
No. It is the Department of Revenue's average tax rate for each county from Table 8 of its 2024 property tax statistics: taxes extended as a percent of equalized assessed value (EAV), in total and by class of property. The rate applies to equalized assessed value, not market value; the share of market value that is assessed was not read from an official source for this page, so no example bill is given.
Did Illinois average tax rates change from 2023 to 2024?
Of the 102 counties ranked here, 98 fell, 3 rose and 1 stayed the same. The largest rise was in Union County (6.65% to 6.79%) and the largest fall in Hardin County (5.24% to 4.48%).
How do I appeal a property assessment in Illinois?
Contest the assessment before the county board of review: by the board of review's own filing deadline, which the Property Tax Appeal Board's rule refers to but does not state.
