How to calculate property taxes in Illinois
To estimate property taxes in Illinois, multiply the home value by the local property tax rate. This page applies the state average effective owner-occupied rate of 1.88%, so a home valued at $500,000 produces a baseline annual estimate of $9,400.
Illinois has some of the highest effective property tax rates in the nation, driven largely by local school and county levies.
Actual tax bills can include county, city, school district, property classification, exemption, and assessment rules, so investors should verify the final number with the local assessor before closing.
