DeKalb County tax sales, Illinois

Verified

DeKalb County publishes the fullest buyer record in this set and one honest defect: its sale page still prints last year's date (Monday, October 27, 2025) as the answer to when the next sale will be held, while its registration text is updated for the current cycle, with forms due October 9, 2026 and the last day to pay on October 23, 2026. This page does not state a 2026 sale date the county itself has not printed. The substance is not in doubt: registration 10 business days ahead, a $500 deposit, a $75 list, open outcry bidding in person at the Administration Building, and a county board purchase list that, for the 2025 tax year, contains all delinquent real estate parcels, which is why the page can also say that all of the liens are sold at the tax sale.

Selling office: DeKalb County Treasurer Becky Springer, as Treasurer and Collector, Administration Building, 110 East Sycamore Street, Sycamore, IL 60178

Next sale: No 2026 date is printed on the county's sale page (its date line is stale at October 27, 2025); registration for the current cycle closed October 9, 2026. The Treasurer's department page gives the cycle anchors the county does publish: 2025 real estate taxes due June 3 and September 3, 2026, and a last day to pay of October 23, 2026. The sale itself is held at 9:00 a.m. in Conference Room East of the Administration Building on the published pattern. Because the county has not printed a 2026 date, this page assigns no 2026 status beyond the completed registration window.

Redemption information is handled by the DeKalb County Clerk's office (815-895-7149), per the sale page.

Dates and deadlines

Next sale	No 2026 date is printed on the county's sale page (its date line is stale at October 27, 2025); registration for the current cycle closed October 9, 2026
Sale date and venue	The sale is held at 9:00 a.m. in Conference Room East, DeKalb County Administration Building, 110 E. Sycamore Street, Sycamore, per the Treasurer's sale page. The page's printed date line is the prior cycle's (Monday, October 27, 2025) and is labeled subject to change; no 2026 date is printed.
Registration	The current year Tax Buyer Registration form must be on file in the Treasurer's Office 10 business days prior to the tax sale; for the current cycle, all forms were due by October 9, 2026. The form is requested from the Collector's Office by email or phone, approximately two weeks after the second installment due date. One buyer per registration may bid.
How bids are placed	Open outcry. The buyer or the registered representative must be physically present at the sale to bid; no other manner of bidding is accepted. Only the accrued taxes, fees and penalties are sold: the buyer is purchasing taxes, not property. The starting penalty and bid down procedure are not published on the sale page; the Code cap is 9 percent under Section 21-215 as amended.
The list and fees	The tax sale list costs $75.00 prepaid, sent when lists become available, generally three to four weeks after the second installment due date. The sale is advertised in the local newspapers after all second installment payments are posted. No per parcel fee itemization is published on the sale page.
The county purchase list	For the 2025 tax year, the DeKalb County Board submitted a list of real estate properties to the Collector that the county wishes to purchase, and that list contains all delinquent real estate parcels. The sale page states the consequence twice, and on unsold liens: all of the liens are sold at the tax sale.
Redemption	Owners redeem through the DeKalb County Clerk. The standard period is 3 years from the sale under Section 21-350 as amended, and 1 year for vacant non-farm, seven or more unit, commercial and industrial parcels.
Format	Open outcry, in person only: Conference Room East, DeKalb County Administration Building, Sycamore
Selling office	DeKalb County Treasurer Becky Springer, as Treasurer and Collector

Research DeKalb 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 DeKalb 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 DeKalb County

Register on the county's current form by its deadline (October 9, 2026 for this cycle), fund the $500 deposit, and be in the room: DeKalb is open outcry and physical presence is mandatory. Read the county purchase list line before valuing any parcel, because the board's list covers every delinquent real estate parcel and shapes what a private bid is competing against.

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

Deposit, DeKalb County	$500.00, applied to purchases at the sale; refunded if the buyer attends but purchases no taxes; forfeited if the buyer does not attend. Certified funds are required for first time buyers, for both the deposit and the tax sale list.
Payment, DeKalb County	Taxes must be paid immediately after the close of the tax sale. Certified funds (cash, cashier's check, money order, or letter of credit with a check) are required for first time buyers; returning buyers may pay by personal, business or cashier's checks. The deposit and list fee may be paid together or separately.
What is sold	The unpaid taxes, as a certificate of purchase: a lien position, not the property and not a deed. A deed exists only at the end of a separate circuit court petition, after the redemption period expires unredeemed and the statutory notices are served.
The bid	A penalty percentage, bid down: the lowest penalty wins the certificate. The cap is 9 percent under Section 21-215 as amended by P.A. 104-553 (effective July 10, 2026). The penalty is charged per six month period or part thereof, on the Section 21-355 schedule.
Redemption	Three years from the sale as the standard, and 1 year for vacant non-farm property, structures with seven or more residential units, and commercial or industrial property (Section 21-350 as amended). Redemption runs through the county clerk. Certificates issued January 1, 2024 to July 9, 2026 carry the prior 2.5 year period, extendable by the holder to no later than 3 years.
Registration	With the collector, at least 10 business days before the first day of sale (Section 21-220). Counties set their own forms and close earlier; in counties of 275,000 or more, the single bidder rule applies.
Costs on top of the amount due	Per parcel sale fees set by the Code, commonly $104 in total ($20 indemnity, $10 advertising, $4 clerk, $10 treasurer automation, $60 sale in error fund, as itemized on Sangamon County's official sale page and Will County's published notice), plus the county's list cost where a buyer buys the delinquency list.

Parcels that draw no bid

The county's position is that all of the liens are sold at the tax sale, with the board's purchase list behind the offering. After the sale, tax lien certificates may be purchased over the counter or by assignment through J. Meyer and Associates, DeKalb County Trustee (618-656-5744), with a list of assignable certificates sold at the trustee's iltaxsale.com DeKalb County page. Parcels the trustee acquires by court order are sold at a Surplus Property Auction (catalog sale) held annually each summer; buyers receive a quitclaim deed recorded at the seller's expense and are not responsible for delinquent taxes.

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.
