How Tax Sales Work at the County Level in Illinois
In Illinois, property tax collection and tax foreclosure sales are administered at the county level. Each county's tax office is responsible for collecting delinquent property taxes and, when necessary, initiating tax sale proceedings. The sale type statewide is Tax Lien, though specific procedures and timelines may vary by county.
County sells tax lien certificates at annual sale; buyer serves 'take notice' before seeking deed
Following the U.S. Supreme Court's decision in Tyler v. Hennepin County (2023), governments cannot retain surplus proceeds from tax foreclosure sales beyond what is owed in taxes, penalties, and fees. If your former property sold for more than the tax debt, you may have a constitutional right to the excess funds. The redemption period in Illinois is 2 years (2.5 years for residential 6 units or fewer).
