Will County tax sales, Illinois

Verified

Will County's 2026 cycle is documented in its published judgment notice: the Treasurer applies to the Circuit Court on November 20, 2026 for judgment on the unpaid 2025 taxes, and the public sale follows on December 1, 2026 at the Will County Office Building in Joliet. Buyers buy the taxes, not the property, and the registration deadline (November 13, 2026) falls before the judgment hearing itself, so Will is a county where the paperwork calendar matters as much as the sale day. The county's published notice also itemizes the buyer fees: $10, $20, $60 and $4 per parcel, plus $60 where back taxes are involved.

Selling office: Will County Treasurer Tim Brophy, as ex officio County Collector

Next sale: Annual tax sale, Tuesday, December 1, 2026, 10:00 AM, Will County Office Building, 302 North Chicago Street, Joliet. Date, time and venue are from the county's published judgment notice for the 2025 taxes, read November 9, 2026. The Treasurer applies for judgment on Friday, November 20, 2026, and buyers had to register by November 13, 2026.

The December 1, 2026 sale covers tax year 2025. The judgment application is set for November 20, 2026, after the November 13 registration deadline.

Research Will County parcels before you bid

A sale list gives you the parcels, the date, and the opening terms. It does not give you the owner, the value, or the rest of the picture: liens, foreclosure status, and parcel history. PropertyRadar is the data platform for that layer. It carries owner records, assessed and market values, foreclosure and tax data, and property history for parcels across Will County, searchable by address, owner, or county, including parcels that never reach a sale list.

How Illinois tax lien sales work

• Judgment comes first. When taxes stay unpaid, the county treasurer, acting as ex officio county collector, applies to the circuit court for judgment and order of sale against the delinquent parcels (Section 21-190). The delinquent list is advertised, and only parcels under judgment go to the sale. There is no deed on offer at any point in this process: Illinois sells the taxes, and the property changes hands only years later, through a separate court case, if it changes hands at all.
• Buyers register early, and bid as one entity. Registration with the collector is required at least 10 business days before the first day of sale (Section 21-220), and counties close their own windows earlier. In counties of 275,000 or more people, the single bidder rule (Section 21-205(b-5)) requires related buyers to bid as one. Since 2013 the sale itself must be run on an automated bidding system or recorded, which is why so many Illinois sales work through RAMS and a USB drive of bids.
• The annual sale sells a lien certificate, priced by a penalty bid-down. Bidding is by penalty percentage and goes down: the lowest penalty wins. Public Act 104-553, effective July 10, 2026, cut the cap in Section 21-215 from 18 percent to 9 percent, so any county page or packet still quoting 18 percent is pre-amendment text. The winner pays the full amount due, plus per parcel sale fees (commonly $104: indemnity, advertising, clerk, treasurer automation and sale in error fund charges), on the day of sale, and receives a certificate of purchase.
• Redemption runs through the county clerk, and the penalty is the return. Under Section 21-350 as amended, the standard redemption period is now 3 years from the sale; it is 1 year if on the sale date the property is vacant non-farm, has a structure with seven or more residential units, or is commercial or industrial. Certificates issued from January 1, 2024 to July 9, 2026 run the prior 2.5 year track, which the holder can extend under Section 21-385 to no later than 3 years. The owner redeems at the clerk's office by paying the certificate amount plus the penalty at the bid rate for each six month period elapsed (the Section 21-355 schedule: the penalty once in the first six months, then two, three, four, five and six times it as the periods run). A redeemed certificate pays the buyer back with that penalty; that is the normal exit.
• The deed is a second, separate case. Only after redemption expires unredeemed can the certificate holder petition the circuit court for a tax deed, serving the statutory notices the Code requires. Until that deed issues, the buyer holds a lien position: no possession, no rents, and a defined set of sale in error risks that can unwind a purchase. Price an Illinois certificate as a timed claim with a court case at the end of it, not as a property purchase.

How bidding works in Will County

Register with the Treasurer by November 13, 2026 for the December 1, 2026 sale. Note the order of the calendar: registration closes before the November 20 judgment hearing, so a buyer who waits for the judgment list has already missed the sale.

• The penalty is the price. The lowest penalty percentage wins, and the penalty is earned per six month period, so a 9 percent bid redeemed in month seven pays twice what the same bid pays in month five. At a 0 percent bid the buyer earns nothing on redemption and is working only for the deed path. Model the redemption track (3 years standard, 1 year for the exception classes) before the number.
• The certificate is not the property. No possession, no rents, no right to enter. The return is the penalty when the owner redeems through the county clerk, or a deed at the end of a court petition if nobody does. Buyers who need the property itself should be reading the Michigan pages, not this one.

Terms: what a bid actually costs

Parcels that draw no bid

Taxes that draw no bid at the annual sale stay delinquent and can be picked up afterward as forfeited taxes or re-offered under the Property Tax Code. The county sources consulted publish no separate leftover schedule for Will County; confirm the current channel with the Treasurer.

Before you bid

• Know the redemption track before the penalty. Three years standard against 1 year for vacant non-farm, seven or more unit, commercial and industrial parcels is the difference between two holding strategies, and the track is set by the property on the sale date, not by the buyer's preference.
• Read the current statute, not the county FAQ. County pages still showing an 18 percent penalty predate P.A. 104-553. For sales after July 10, 2026 the cap is 9 percent and the standard redemption period is 3 years; where a county page and the Code disagree, the Code governs.
• Registration closes earlier than you think. The statutory floor is 10 business days, and counties close sooner: Will County's deadline fell before its judgment hearing, and DuPage closed registration on October 30 for a November 19 sale. A buyer who starts with the sale list has usually started too late.
• Price the deed path honestly. Notices, a court petition, and sale in error risk sit between a certificate and a deed, and redemption is the common exit. Set the maximum before the sale opens; the free Max-Bid Calculator below works backwards from your exit value.
