Over-the-counter (leftover) purchases
unsold liens and deeds
Certificates nobody bids on at the annual sale are forfeited to the county as trustee for the taxing districts. The county may then assign a forfeited certificate to any party or sell property it has acquired, which many counties handle through a delinquent tax agent rather than a public counter. Counties may also offer county-held certificates at a scavenger sale with a minimum bid of $250, or half the tax when total liability is under $500. Ask the county collector and the county clerk which program the county runs and who may buy.

Illinois rules
- Redemption
- Property sold at an Illinois tax sale may be redeemed at any time before the redemption period expires. Public Act 104-0553 set the standard period at 3 years from the date of sale for tax certificates issued on or after July 10, 2026. Certificates issued between January 1, 2024 and July 9, 2026 run on the earlier 2.5 year (30 month) track, and on that track the certificate holder could file a written notice with the county clerk extending redemption to a date no later than 3 years from the sale. A short 1 year period applies when the parcel was, on the date of sale, vacant non-farm property, commercial or industrial property, or improved with a structure holding 7 or more residential units. Certificates the county holds or assigns as trustee run on their own schedule under Section 21-385, and an assignee must file notice within 60 days of assignment setting a redemption deadline no later than 3 years from the assignment.
- Deed deposit
- Illinois does not fix a statutory deposit percentage. Deposit and payment terms are set in the court's order authorizing the auction and by the selling officer, so read the notice of tax deed auction for each sale. A purchaser who fails to complete the sale forfeits any deposit already made to the county surplus equity fund, and the court orders a new auction of the property.
- Surplus proceeds
- Any amount by which the winning bid exceeds the minimum bid is surplus. Within 30 days after the court confirms the sale the selling officer deposits the surplus with the county treasurer, who notifies everyone who received the Section 22-10 take notice that the owner at the time of the sale may file a claim for it. A county running its own tax deed auction deposits surplus with the treasurer within 30 days of the sale and notifies interested parties within 60 days. Separately, a previous owner who lost equity through a tax deed can claim an award from the county surplus equity fund, capped at the value of the property when the deed issued less mortgages, liens, and the taxes the purchaser paid.
A tax deed does not convey marketable title. Most buyers file a quiet title action before they can resell or insure the property. See the due diligence guide.
