Illinois delinquent tax lists by county
Short answer: Illinois is a lien state, so a winning bidder gets a tax lien certificate, which pays interest if the owner redeems and can be foreclosed into ownership if they do not. Annual tax sales use penalty-rate bidding with a 2 to 3 year owner redemption before a tax deed. Each county publishes its own delinquent roll through the County Treasurer.

Illinois delinquent tax list FAQ
Is Illinois a tax lien or tax deed state?
Illinois is a lien state. A winning bidder gets a tax lien certificate, which pays interest if the owner redeems and can be foreclosed into ownership if they do not. Annual tax sales use penalty-rate bidding with a 2 to 3 year owner redemption before a tax deed.

How long does an owner have to redeem in Illinois?
Annual tax sales use penalty-rate bidding with a 2 to 3 year owner redemption before a tax deed. That window is the single biggest thing separating a good tax-sale trade from a bad one, because it decides how long your money sits before you can act.
How many tax-delinquent properties are there in Illinois?
Across the 102 Illinois counties we track, roughly 45,849 properties currently carry at least one distress signal in public records, including tax delinquency, foreclosure filings, vacancy and long-distance ownership. The counts refresh daily.
Can I buy Illinois tax-delinquent property before the auction?
Yes. The delinquency appears in the public record months before any sale is scheduled, and during that window the owner can still sell normally. That is the whole opportunity: no bidding war, an inspection is possible, and an owner with equity walks away with money instead of nothing.
