About Property Taxes in Illinois

Illinois has one of the most distinctive property tax systems in the country: taxes are paid one year in arrears. This means the taxes you pay in 2025 are for the 2024 tax year. This delayed billing cycle can catch new homeowners off guard — when you purchase a home in Illinois, you will typically receive a credit at closing for the prior year's unpaid taxes. Property taxes in Illinois are administered at the county level. County assessors (or township assessors in some areas) set property values, the county board of review hears appeals, the county clerk calculates tax rates, and the county treasurer bills and collects. Tax rates vary significantly depending on the number of overlapping taxing districts — counties, municipalities, school districts, park districts, fire protection districts, and others — affecting your property.

Payment & Assessment

Illinois property taxes are generally paid in two installments, though timing varies by county: Cook County: First installment: Due March 1 Second installment: Due August 1 Other counties: Many follow a June and September schedule, but dates vary. Contact your county treasurer for exact due dates. Late payments accrue interest at 1.5% per month (18% annually). If taxes remain unpaid for an extended period, the county may sell the tax lien to investors at an annual tax sale, which can ultimately lead to loss of the property if the lien is not redeemed. Most counties offer online payment through the county treasurer's website. Contact your county treasurer to confirm whether partial payments are accepted.
