How Grant County sells delinquent taxes

No tax lien certificate sale

Wisconsin counties sell no tax lien certificates to investors. Under s. 74.57(1) the county treasurer issues the tax certificate to the county itself, and s. 74.57(3) states that the county may not sell, assign, or otherwise transfer it. The section carries two carve-outs, and neither admits a bidder: a county may sell its right to receive tax certificate revenues under s. 74.635, which is a payment stream rather than a lien, and the county treasurer must reissue certificates to a city acting under s. 74.87 that has paid the delinquent taxes under an agreement made under s. 74.83.

Notice of Unredeemed Lands
When it runs
Grant County sets no annual sale month. The calendar runs from the date the county takes title. The Treasurer's Notice of Unredeemed Lands states that unless the listed taxes and interest are paid on or before September 1, "the same will be conveyed by tax deed to Grant County." County ordinance then gives the Treasurer 180 days from acquisition, for parcels taken on or after January 1, 2026, to publish the listing and the appraised value on the county website and by class 1 notice.
Registration and deposit

There is no standing bidder registry and no online bidder account. Each offering is advertised by class 1 notice and posted on the county website, and that publication states the method of sale and how bids must be submitted. Bids are handled by the Treasurer's office in Lancaster. The Treasurer also notifies the clerk of the municipality where the parcel sits at least three weeks before the sale.

Sale format and venue
Wisconsin counties sell no tax lien certificates to investors. The September 1 tax certificate is issued to Grant County itself and only starts the redemption clock, so there is no investor certificate auction here. The event to watch is the county selling land it already holds by tax deed. Grant County Code Chapter 242, Article I, amended March 17, 2026, delegates to the Treasurer the power to acquire, manage and sell tax-deeded lands under the general oversight of the Executive Committee. The Treasurer sets an appraised value, normally the market value on the most recent tax bill issued before the county took title, and on the first attempt to sell a parcel "every bid less than the appraised value of the tax-deeded land shall be rejected." A parcel that fails to sell may later go for any amount the Treasurer determines, but only after a fresh class 1 notice, and any sale below the appraised value or below the highest bid needs Executive Committee approval plus a written explanation open to public inspection. The county names no standing online auction platform, so read the method of sale off each sale publication. Two claims can pull a parcel before bidders reach it: the former owner of an owner-occupied single-family residence may repurchase within 60 days of the county's acquisition by clearing all liens of record and county costs, and the Treasurer may offer a parcel to the municipality it sits in ahead of the general public, subject to Executive Committee and full County Board approval.

Grant County tax sale list and auction calendar

For Grant 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. Get the advertised list

    Use Notice of Unredeemed Lands for the current advertised parcels, then recheck it before the auction.
  2. Register to bid

    There is no standing bidder registry and no online bidder account. Full requirements are in the sale card above.
  3. Sale day

    Grant County sets no annual sale month. Bidding runs on Wisconsin Surplus Online Auction, the shared platform many Wisconsin counties use for tax delinquent real estate; check posted sale dates, registration status, and bidding windows there.
  4. Confirm with the office

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

Before you bid in Grant County

  1. Start with the live sale list

    Pull the current advertised parcels from Notice of Unredeemed Lands. Lists can change before the sale, so recheck the county source before you price a parcel.
  2. Confirm registration and deposit

    There is no standing bidder registry and no online bidder account. Each offering is advertised by class 1 notice and posted on the county website, and that publication states the method of sale and how bids must be submitted. Bids are handled by the Treasurer's office in Lancaster. The Treasurer also notifies the clerk of the municipality where the parcel sits at least three weeks before the sale.

  3. Check the state rules that change the bid

    Read the Wisconsin 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 Wisconsin 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

Wisconsin has no statewide over-the-counter program at a fixed statutory price, and no state-held certificate to assign. County inventory is what stays for sale. The county board may sell its tax-deeded lands on whatever terms it sets, may hire licensed real estate brokers on commission, and may advertise on a multiple listing service, so a county parcel can sit on the open market between sales. Once a parcel has been advertised and not sold, the county may sell it for any amount after a further class 1 notice, subject to board or committee approval below the appraised value. Ask the county treasurer or the land committee for the current list of unsold county-owned parcels and make a written offer. Approval still runs through the board or its committee, so nothing closes on the day.

County notes

  • Grant County posts a list of tax-deeded parcels only when a sale has been authorized. Between sales there is no list to check, so call the Treasurer at (608) 723-2604 to ask what the county currently holds and watch the official county newspaper for the class 1 notice.
  • The list the county does publish every year is the Notice of Unredeemed Lands. It names the parcels that pass to Grant County by tax deed if they are not redeemed by September 1, so treat it as the pipeline of future county-owned inventory rather than a list of parcels for sale.
  • The 2026 notice covers parcels whose tax certificates were issued September 1, 2024 for unpaid 2023 taxes, with redemption closing September 1, 2026.
  • On March 17, 2026 the County Board approved Resolution 2026-06 authorizing the Treasurer to take tax deeds on parcels with taxes owing on the 2022 tax rolls under the 2023 tax certificate.
  • The Treasurer's foreclosure timeline puts 12% interest on delinquent parcels, publishes the owner's name in the newspaper one year after the missed payment, and starts tax foreclosure by certified mail two years after the tax certificate is issued.
  • Sheriff sales listed by the Grant County Sheriff's Office are mortgage foreclosures and are a separate track from tax-deeded land sales run by the Treasurer.

Wisconsin rules

Redemption
The redemption right in Wisconsin runs against the county, and it is over before an investor sees the parcel. Issuance of the tax certificate on September 1 starts the clock. Two years later the county may take its deed or start a foreclosure, but the right to redeem does not end on that anniversary: under s. 75.01(1)(b) any person may redeem at any time before the tax deed is presented to the register of deeds and accepted for record, and a redemption before recording makes the deed void as to the land redeemed. On the in rem route under s. 75.521 the county publishes a notice fixing the last day for redemption at least 8 weeks after first publication, and an interested party may instead serve a verified answer within 30 days after that date on the three grounds the section allows. Once the deed is recorded or judgment is entered, redemption is finished. Between the two, at least 6 and not more than 10 months before the redemption period expires, the county treasurer must publish a class 2 notice listing every unredeemed parcel with its amount due and the last day of redemption, which is the public list an investor can watch. Two things can still pull a parcel off a sale list afterward: the minor and incompetency extension in s. 75.03, and the former owner repurchase right in s. 75.35(3).
Deed deposit
Wisconsin fixes no statutory deposit. Section 75.35(2)(am) lets the county board sell its tax-deeded lands in whatever manner and on whatever terms it sets by ordinance or resolution, and s. 75.35(2)(d) lets the board delegate that power to a committee, an officer or a department, or hire licensed real estate brokers on commission. Deposits are county rules, not state law. St. Croix County requires a 10 percent deposit by cashier's check or money order with each sealed bid and rejects personal checks. Counties selling through the statewide online auctioneer instead take payment by certified check or wire transfer under the platform's terms. Read the county's own bid packet before you bid.
Homestead deeds
Owner-occupied homes are treated differently, and the difference can pull a parcel off the list. For single-family, owner-occupied properties the county board must by ordinance give the former owner who lost title, or that person's heirs or beneficiaries, the right to buy the land back before it is sold, on paying the costs and expenses under s. 75.36(3)(a), the property taxes that would have been owed for the year of the purchase, and enough to satisfy any other liens at the time of foreclosure plus the county's repurchase costs. The board may extend the same right to other property types at its option. A sale under that ordinance is exempt from s. 75.69 altogether, so it never reaches a public bid. Counties set their own window. Dane County gives the former owner 60 days from delivery of the treasurer's certified-mail notice. Treat an owner-occupied house on a Wisconsin land sale list as provisional until the repurchase window has closed.
Surplus proceeds
Wisconsin returns the surplus to the former owner, and the county treasurer has to go find them. On taking the tax deed the treasurer must notify the former owner by registered or certified mail, at the mailing address on the tax bill, that the former owner may be entitled to a share of the proceeds of a future sale. When the county sells, the treasurer computes net proceeds by subtracting foreclosure, record-keeping, legal, advertising and title insurance costs, the actual maintenance, board-up, clean-up and demolition costs reasonably needed to sell, real estate agent or broker fees, and all unpaid general property taxes, interest, penalties, special assessments, special charges and special taxes. From the net proceeds the treasurer pays any managed forest withdrawal tax and fee, then the taxing jurisdictions' special assessments and special charges, prorated if the money runs short. Anything still remaining goes to the former owner, less any delinquent taxes, interest and penalties that person owes the county on other property. A payment unclaimed one year after mailing becomes unclaimed funds under s. 59.66(2), and no interest is paid on any of it.
Governing statute
Wis. Stat. ch. 74

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.
