Illinois homestead exemption
- Illinois's general homestead exemption lowers a home's equalized assessed value by its increase over the 1977 value, up to $10,000 in Cook County, $8,000 in the counties bordering Cook and $6,000 elsewhere.
- Owners 65 or older get a further $8,000 of equalized assessed value off in Cook and bordering counties and $5,000 elsewhere; the senior assessment freeze is open to households with income of $75,000 or less for tax year 2026, $77,000 for 2027 and $79,000 from 2028.
This is the property tax homestead exemption, not the homestead exemption that protects a home from creditors in bankruptcy.

Does Illinois have a homestead exemption?
Illinois's general homestead exemption lowers a home's equalized assessed value by its increase over the 1977 value, up to $10,000 in Cook County, $8,000 in the counties bordering Cook and $6,000 elsewhere. The calculator does not subtract it: the rates already reflect the exemptions owners received.
Why might a Illinois tax bill differ from this estimate?
The rate is what owner-occupiers in Illinois paid on average in 2020 through 2024, as a share of their homes' value. An actual bill depends on the home's assessed value, the levies where it sits and the exemptions its owner claims.
What the calculator leaves out
- The rate is the total real estate tax owner-occupiers reported paying divided by the total value they reported for their homes, not a tax rate set by law.
- The rate already reflects the exemptions, caps and credits typical owner-occupiers received, so the calculator does not subtract a homestead exemption again.
- An actual bill depends on the home's assessed value, the levies where it sits and the exemptions its owner claims.
- Survey estimates for small counties have wide margins of error.
Rates and medians are American Community Survey 2020-2024 5-year estimates: taxes owners paid in those years, not 2026 bills.
