Illinois tax sales
lien state
Illinois counties sell the delinquent property taxes themselves, not the property: at the annual tax sale run by each county treasurer (as county collector), buyers bid on the penalty rate they will accept, and the lien goes to the lowest bid, capped by statute at 9%. Outside Cook County, the collector must apply for judgment and sale within 90 days after the second installment due date, so most collar-county sales fall in October through December; Cook County's Treasurer says it anticipates holding the next annual sale in December 2026. Owners can redeem within a statutory period (generally up to 2.5 years from the sale, shorter for some property classes); if they don't, the buyer may petition for a tax deed. Separately, scavenger sales offer taxes delinquent for several years; Cook County says these are now held only at the direction of the County Board. New for the 2026 sales: under Public Act 104-0553 some counties, McLean among them, have chosen to take the delinquent real estate taxes themselves, so only mobile home taxes are offered to private buyers there. Check each county’s page before you register.

Illinois tax sale questions
Does Illinois sell tax liens or tax deeds?

Check each county’s page before you register.
When is the next tax sale in Illinois?
The next dated sale we have is in Morgan County on Mon, Nov 2, 2026: Tax Sale (2025 taxes). Counties add and cancel sales often, so confirm on the county's page before you plan around it.
