How to buy tax-sale property in Wisconsin (2026)

1. 1.Confirm the county holds a tax deed: after the redemption period runs, the county enforces the delinquent taxes by tax deed (or by foreclosure of the certificate) and the liens merge in the county's title (Wis. Stat. 75.19, 75.36(2)(a))
2. 2.Find the county's advertised sale: the sale and the appraised value must be advertised on the county website plus a class 1 notice or an MLS listing, generally no later than 240 days after acquisition (180 days beginning in 2026) (Wis. Stat. 75.69(1))
3. 3.Submit a bid the way the county's ordinance provides: the county board may sell by open or closed bid, by broker, and on terms it sets by ordinance or resolution (Wis. Stat. 75.35(2)(am), (2)(d))
4. 4.Where the county advertises under the class 3 notice route, file a written bid at the place and by the date stated in the notice for real estate delinquent at least four years (Wis. Stat. 75.69(1m)(b))
5. 5.Clear the price floor: at the first attempt every bid under the appraised value is rejected, and below-value or below-highest-bid acceptances need board approval or a written explanation (Wis. Stat. 75.69(1))
6. 6.Close with the county: the county clerk executes the deed or land contract, and the county treasurer distributes the net proceeds, including any share owed to the former owner (Wis. Stat. 75.35(2)(c), 75.36(3))

At the first attempt to sell, every bid below the appraised value must be rejected (Wis. Stat. 75.69(1))

A county may accept the bid most advantageous to it, but selling below the appraised value needs county board or committee approval, and selling below the highest bid needs a written statement of reasons open to public inspection (Wis. Stat. 75.69(1))

The former owner of single-family, owner-occupied property may hold a repurchase right set by county ordinance (Wis. Stat. 75.35(3))

PaymentHow and when you must pay after winning. Certified or cleared funds are common and personal checks usually are not; missing the deadline typically forfeits your deposit. See the full glossary for more terms.

In Wisconsin the county, not a private bidder, takes the tax certificate and then the tax deed, so the bidder's entry point is the county's later sale of tax-deeded land under ss. 75.35 and 75.69. The county board sets the manner and terms by ordinance, may sell by open or closed bid, by broker, or through an MLS listing, and must reject first-round bids below appraised value. Because those terms are local, bidder registration, deposits, forms and payment methods are not fixed in the cited statutes and remain unknown.
