Annual sale held in January, after both installments of the prior year's bill come due. The Treasurer's Office page states: "Tax Sale will be scheduled for January 14, 2027 at 9:00 AM at the Monroe County Courthouse for 2025 tax bills payable in 2026." The Illinois County Treasurers Association profile for Monroe County lists the same January 14, 2027 sale date for unpaid 2025 taxes, with installments due September 18, 2026 and November 6, 2026.
Registration and deposit

Prospective buyers file a Certificate of Registration with the Monroe County Treasurer and Collector, executed under 35 ILCS 200/21-220. The form posted by the office asks for the name in which certificates of purchase are to be issued, mailing address, tax ID number, phone, fax or email, and the authorized agents or employees who may bid and receive certificates. The posted version was prepared for the 2020 tax sale held in January 2022, so confirm the current registration deadline, any registration fee, and deposit terms with the office at 618-939-8681 ext. 213 before the sale.

Sale format and venue
Monroe County holds its annual delinquent tax sale in person at the Monroe County Courthouse in Waterloo, and no online bidding portal is confirmed for this county, so verify procedures with the Treasurer's Office. The county's registration form shows the sale being conducted in the West Meeting Room of the courthouse. The Treasurer's Office describes the sale as selling the taxes rather than the property: "If taxes are delinquent, the Treasurer/Collector must 'sell' the taxes, not the property, in order to collect and distribute the amount due the taxing bodies." Redemption runs through a different office: "To redeem the taxes, a property owner must pay the total amount of taxes due, including subsequent year's taxes if delinquent, interest and penalties to the Monroe County Clerk's Office." The county does not publish the delinquent parcel list on its website, so request the list from the Treasurer's Office. Caution on third-party sites: the ILTaxSale.com page for Monroe County shows no scheduled auctions and points readers to a different Illinois county's website, so it is not the county's sale portal and should not be used to track this sale.

When it runs

Over-the-counter (leftover) purchases

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

Max interest rate
9% per redemption period maximum, bid down at auction
Minimum return
No statutory minimum return; what you earn is set by the penalty rate at the sale
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.
Governing statute
35 ILCS 200, Articles 21 and 22

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.
