Illinois property tax averages about 2.08% of a home’s value each year. This estimator applies that statewide effective rate to your home value to project an annual and monthly property tax bill for Illinois in 2026.

How it works

Illinois’s average effective property tax rate is 2.08% — the statewide ratio of property tax actually paid to market value. The estimate applies that rate to your home’s value after any homestead exemption:

taxable value = home value - homestead exemption
annual tax    = taxable value x 2.08%
monthly tax   = annual tax / 12

The tool can also subtract Illinois’s homestead exemption of $6,000 from the value before applying the rate. Illinois’s General Homestead Exemption removes up to $6,000 of equalized assessed value ($10,000 in Cook County) for owner-occupied primary residences.

Example

Take a $400,000 home in Illinois. Applying the $6,000 homestead exemption first gives a taxable value of $394,000, so the estimated annual tax is $394,000 × 2.08% = about $8,195 ($683 per month).

Notes

This is an estimate only and not financial or tax advice. It uses Illinois’s 2.08% statewide average effective rate; your actual bill depends on local county, city, and school-district millage, assessment ratios, assessment caps, and any local exemptions or credits. For an exact figure, confirm with the Illinois Department of Revenue and your county assessor.
