How Grundy County sells delinquent taxes

Tax certificate sale (lien)

In person
Run by
Grundy County Treasurer and County Collector
Frequency
annual
Typical timing
Early November, in person.
When it runs
Early November, in person. The Clerk's redemption page describes the Annual Tax Sale as "usually held in early November." The Treasurer's website states "The 2024 payable 2025 property tax sale was held November 4th, 2025, at 9am" and that "Future tax sales are held at the Grundy County Administration Building located at 1320 Union St, Morris, IL 60450." The county has not posted a date for the 2026 sale, so confirm it with the Treasurer's Office.
Registration and deposit

Bidders register with the county collector before the annual tax sale, and the pre-sale advertisement in counties under 3,000,000 inhabitants must carry notice of that registration requirement. Deposit or bond amounts are set by the county. Counties with 275,000 or more inhabitants must adopt a single bidder rule that bars a tax buyer from registering more than one related bidding entity, and smaller counties may adopt one by ordinance. Bidding is a reverse auction on penalty percentage: the lowest penalty wins and no bid above 9 percent is accepted. Confirm the platform, deposit, and registration deadline on the county collector page.

Sale format and venue
Grundy County has changed who buys at its annual sale. The Treasurer's notice states that, "Pursuant to Illinois Public Act 104-0553 and the standing direction of the Grundy County Board," the Treasurer, acting as County Collector, "will sell all legally eligible delinquent property tax liens or certificates offered at future annual tax sales to Grundy County, as Trustee for the taxing districts." The notice adds that this acquisition transfers the tax lien or certificate, not immediate title to the property. Investors who bought certificates here in past years should not expect to buy any at future annual sales, so confirm with the Treasurer's Office whether any parcels will be offered to private buyers before planning to attend. The sale itself is held in person at the Grundy County Administration Building, 1320 Union St, Morris, and the county names no online auction platform. After October 1, a $10 publication fee is added to all delinquent parcels, and late payments carry a 1.5% monthly penalty. Owners whose taxes were sold redeem at the County Clerk's office, not the Treasurer's.

Tax deed sale

Run by
Sheriff or a court-appointed private selling officer, under an order of the circuit court. A county acting as trustee runs its own tax deed auctions.
Frequency
as ordered by the circuit court
Typical timing
Within 120 days after the court order authorizing the auction.
When it runs
Within 120 days after the court order authorizing the auction. Public Act 104-0553 created this route for tax certificates issued on or after July 10, 2026, so the earliest Illinois judicial tax deed auctions fall in 2027, after the 1 year short redemption track runs.
Registration and deposit

Terms of a judicial tax deed auction, including whether it runs online, in person, or both, and what deposit is required, are set in the court's order and published in the notice of tax deed auction. That notice runs once a week for 3 consecutive weeks, starting no more than 45 days and ending no less than 7 days before the auction. Read the notice for each parcel; there is no statewide platform or standing bidder registration.

Sale format and venue
Bidding opens at the tax deed judgment amount plus 0.75 percent per month since judgment, plus publication and selling officer costs. The petitioning certificate holder is entered as a credit bidder at that minimum. Surplus above the minimum goes to the county treasurer for the former owner to claim.

Grundy County tax sale list and auction calendar

For Grundy County tax sale 2026 searches, use the county-run sources below rather than a copied parcel list, and confirm the parcel, registration cutoff, deposit, and payment deadline against the county before you bid. If the parcels on this list are vacant land rather than houses, what buying land at a tax sale hands you is the place to start.

  1. Confirm the advertised parcel list

    No link to the county's sale list is on record here. Get the current list from the Grundy County Treasurer and County Collector rather than relying on a copied one.

  2. Register to bid

    Ask the Grundy County Treasurer and County Collector how and when to register; many counties close registration days or weeks before the sale.

  3. Sale day

    Within 120 days after the court order authorizing the auction. The sale is live and in person; there is no online bidding platform. Confirm the venue and hour with the Grundy County Treasurer and County Collector before you go.

  4. Confirm with the office

    If the list, platform, and notice disagree, use the Grundy County Treasurer and County Collector as the source to confirm which parcels are actually offered.

Before you bid in Grundy County

  1. Confirm the parcel list before pricing

    This page has no link to the county's sale list. Ask the Grundy County Treasurer and County Collector where the list is published and confirm the advertised parcels before you price a bid.

  2. Confirm registration and deposit

    Terms of a judicial tax deed auction, including whether it runs online, in person, or both, and what deposit is required, are set in the court's order and published in the notice of tax deed auction. That notice runs once a week for 3 consecutive weeks, starting no more than 45 days and ending no less than 7 days before the auction. Read the notice for each parcel; there is no statewide platform or standing bidder registration.

  3. Check the state rules that change the bid

    Read the Illinois due-diligence checklist before bidding. Redemption, liens that survive a tax deed, title cleanup, and payment deadlines can change what a parcel is worth. Which liens survive is state law, so read what survives a tax deed in Illinois before you price the title work.

  4. Set a walk-away number

    Work out what the parcel is actually worth with the rural land value estimator, then turn it into a ceiling with the tax deed max-bid calculator.

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.

County notes

  • Redemption is handled by the Grundy County Clerk, not the Treasurer. The Clerk's page states sold real estate taxes "must be paid in full by certified funds only," meaning cashier's check, certified check, or money order payable to Grundy County Clerk, with exact cash accepted in person. Interest accrues at six month intervals from the sale date, current unpaid taxes can be added to a prior sale after the second installment deadline, and a petition for tax deed is typically filed three to six months after the redemption period expires. Grundy County Clerk and Recorder, Kay Olson, 111 E. Washington Street, Rooms 10, 11 and 12, PO Box 675, Morris, IL 60450, phone (815) 941-3222.
  • Free parcel level research is available at the Grundy County Property Tax Inquiry portal, https://grundyil.devnetwedge.com/, which supports parcel number, owner name, address, sales criteria, and mobile home searches.
  • Grundy County will acquire all legally eligible delinquent tax liens or certificates at future annual tax sales as trustee for the taxing districts, under Public Act 104-0553 and a standing direction of the County Board, so private tax buyers should not expect certificates to be offered.
  • The Treasurer lists 2025 payable 2026 installment due dates of Friday, June 26 and Friday, September 4, and a mobile home tax due date of Friday, August 28, 2026. Payments made on or after October 1 must be in cash, cashier's check, credit card, or money order.
  • The Treasurer is Todd Koehn. Office hours are Monday through Friday, 8:00 a.m. to 4:30 p.m.

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. Once 30 days have passed 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.
