Illinois county property tax rates, 2024

Jackson County had the highest average tax rate for tax year 2024, billed in 2025: 9.65 per $100 of equalized assessed value (EAV). Hardin County had the lowest, 4.48, and the middle county, Coles County, 7.39. Of the 96 counties with both years shown, 92 saw the rate fall from 2023 and 3 saw it rise. EAV is not market value, so these rates run far above the effective rates in the table above; each county page shows what an average home pays in each city.

Average tax rate per $100 of EAV, from the Illinois Department of Revenue, Property Tax Statistics, Table 8 (2024). The total rate covers all property in the county and equals the county's taxes extended divided by its EAV in IDOR's Table 1; the residential rate covers homes only. Highest first. Left out: Hamilton County, Livingston County, Putnam County, Washington County, where Table 8's 2024 rate does not match taxes extended divided by EAV in Table 1, and we could not tell which is right. A blank 2023 cell means the same conflict for 2023.
