Information only, not investment or legal advice. Sale dates, terms and deadlines change; always confirm with the county before you register or bid.

Upcoming sales

No specific date posted. Treasurer's page: "The Treasurer's Office anticipates holding the next Annual Tax Sale in December 2026." The Treasurer's annualtaxsale.aspx page still shows the Tax Year 2022 sale (December 2024), and the scavengersale.aspx page shows 2019 details, so both are out of date. A news report (Capitol News Illinois, not an official source) says HB 598 moved the sale to Dec. 1, 2026; we did not confirm this on an official page, so it is not recorded as a date.
