How Monroe 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.

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.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
unsold properties
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
- The tax deed land sale is run by the Property & Facilities Department, not the Treasurer. Direct parcel and bidding questions to Facilities & Property Director Derek Pierce at (608) 269-8794; the Treasurer's office handles delinquent tax collection and payoffs.
- Deed and transfer questions go to the Monroe County Clerk at 202 South K Street, Room 1, Sparta, WI 54656, phone (608) 269-8705, and closing takes place at the Clerk's office.
- Sales appear only when the county has foreclosed parcels ready to offer, so the county bid portal can sit empty between offerings and the auction link comes down after a sale closes. Watch the Foreclosed Properties page and the bid portal for the next posting.
- Under Wis. Stat. 75.69 the first offering of a parcel cannot be sold below its appraised value, and Monroe County publishes a required opening bid for every lot on the auction listing.
- Wisconsin Surplus lists tax delinquent real estate for many Wisconsin counties on one site. Confirm the auction title names Monroe County before relying on any closing date.
- The Property & Facilities Committee meets the second Wednesday of each month at 4:30 p.m., and its agendas and minutes are posted by year on the county site.
- Parcels are sold as is, where is, with no warranty on use, condition, title, access or occupancy. Several 2026 lots were landlocked, so confirm legal access and zoning with the town, village or city before bidding.
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.
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.
