Stat. chapter 75 faq: - question: Can an investor buy a Wisconsin tax lien certificate? answer: >- No. On September 1 the county treasurer issues the tax certificate to the county itself, and s. 74.57(3) bars the county from selling, assigning or otherwise transferring it. No auction offers one to bidders. A county page announcing that a tax certificate was issued is describing that filing, not a sale. - question: What sale can an investor actually bid at in Wisconsin? answer: >- The county land sale under s. 75.69, held after the county already owns the parcel. Counties call it a tax deed land sale, a county-owned property sale, a surplus land sale or a foreclosed property sale. Section 75.69(4) allows open or closed bid, so the format ranges from an online auction to a sealed bid opened at a committee meeting to a broker listing. - question: How long is the Wisconsin redemption period? answer: >- Two years from the September 1 the tax certificate was issued, before the county may take a tax deed or start a foreclosure. It drops to 12 months where a city or village razing cost sits in the amount due, and where the certificate is held by a county of 750,000 or more or by a 1st class city collecting its own taxes. - question: What is the minimum bid at a Wisconsin county land sale? answer: >- On the first attempt to sell a parcel, every bid below the appraised value must be rejected. Appraised value is set by the county board, a committee it designates, or a certified appraiser, so it is neither the assessed value nor the unpaid tax. If the parcel does not sell, the county may later sell it for any amount after advertising again, with board or committee approval for a price below appraised value. - question: When are Wisconsin tax deed land sales held? answer: >- There is no statewide sale date and no sale month. Each county sets its own, and the clock runs from acquisition rather than the calendar. The county must advertise the parcel and its appraised value within 240 days of acquiring it, and within 180 days for property acquired from 2026. Notice also reaches the municipal clerk at least 3 weeks beforehand. - question: Can an owner-occupied house be pulled off the list after I bid? answer: >- It can. For single-family owner-occupied property the county board must by ordinance let the former owner, or their heirs or beneficiaries, buy the land back before the county sells it, and a sale under that ordinance is exempt from s. 75.69 altogether. Dane County allows 60 days from delivery of the treasurer's certified-mail notice. - question: Do restrictive covenants survive a Wisconsin tax deed? answer: >- Yes. Section 75.14(4) keeps valid restrictions and covenants running with the land enforceable to the same extent they would be against a voluntary grantee of the prior owner. Covenants creating a debt or a lien do not survive, with carve-outs for keeping the premises sightly, contributing to private road maintenance and abating undesirable conditions. sources: - label: 'Wis.

No county sells a tax lien certificate, and no private holder earns a rate. The treasurer issues the certificate to the county itself, and two years later the county takes the land. Everything an outside buyer can bid on happens after that, when the county sells property it already owns.
The law runs from Wis. Stat. ch. 74 for collection and chapter 75 for land sold for taxes. The Wisconsin tax sales hub lists the treasurers, how to buy tax deed land in Wisconsin walks the sequence, and tax liens compared to tax deeds covers why neither label fits.
Step 1: The bill goes delinquent and the interest stays with the county
Wisconsin property taxes are payable in full by January 31, or in installments due January 31 and July 31. Miss the first and the whole unpaid balance is delinquent on February 1; miss the second and it is delinquent on August 1.
Interest then runs at 1 percent per month or fraction of a month, counted from the preceding February 1, and a county board may add a penalty of up to 0.5 percent per month by ordinance. Together they reach 1.5 percent per month, or 18 percent a year, uncompounded, and the treasurer keeps it all.
Step 2: On September 1 the county issues the certificate to itself
Here is the step that gets misread. Each September 1 the treasurer issues one tax certificate to the county, covering every parcel whose taxes and special charges were unpaid at the close of business on August 31. Section 74.57(3) then bars the county from selling or assigning it. Within 90 days the treasurer mails every owner notice that failure to pay moves ownership to the county.
Nothing changes hands and no bidder is admitted. A county page announcing a September 1 tax certificate is describing that filing, and calendars printing it under a sales heading mislead buyers every autumn. Section 74.635 is the other lookalike: it lets a county sell its right to receive certificate revenues, a financing transaction over a payment stream that conveys no lien and no route to a deed.
Step 3: Redemption runs against the county and closes before you arrive
Redemption is 2 years from the September 1 the tax certificate was issued, before the county takes title; 1 year where municipal razing costs are included in the amount due, or where the certificate is held by a county of 750,000 or more or by a 1st class city collecting its own taxes.
Section 75.01(1)(b) lets any person redeem, not the owner alone, and the right outlives that anniversary: redemption stays open until the tax deed reaches the register of deeds and is accepted for record, and redeeming before recording voids the deed as to that land. Where a county has adopted the in rem method, the published notice fixes a last day for redemption at least 8 weeks after first publication.
The public list worth watching comes from s. 75.07. Between 6 and 10 months before the period runs out, the treasurer must publish a class 2 notice naming every unredeemed parcel with its amount due and last day of redemption. That is the earliest reliable look at what may reach a sale. Redemption periods explained sets the Wisconsin clock against other states.
Step 4: The county takes title by one of three routes
Two years after issuance the county may take a tax deed under s. 75.14, foreclose the certificate like a mortgage under s. 75.19, or foreclose in rem under s. 75.521. Every route ends with title in the county in fee simple.
On the deed route the county must first serve written notice of application for tax deed on an owner of record, any occupant of a dwelling or business building, and a mortgagee of each unsatisfied recorded mortgage, then wait 3 months and pass a board resolution. Milwaukee is its own case: s. 75.06 treats a 1st class city collecting its own taxes as a county, so the city forecloses in its own name.
Step 5: The sale you can bid at is the county land sale
Sections 75.35, 75.36 and 75.69 govern what comes next. This is the investor event. Counties label it a tax deed land sale, a county-owned property sale or a surplus land sale. Section 75.69(4) allows open or closed bid, so one county runs an online auction while its neighbor takes sealed bids, and a county can switch formats from season to season.
There is no statewide sale date and no sale month. The clock runs from acquisition: the county must advertise the parcel and its appraised value within 240 days of acquiring it, and within 180 days for property acquired from 2026. The advertisement goes on the county website plus either a class 1 notice or a multiple listing service, and notice reaches the municipal clerk 3 weeks ahead. A county of 750,000 or more gets up to 36 months for the classes in s. 75.69(1m).
One contractor carries much of the volume. Wisconsin Surplus Online Auction of Mount Horeb lists tax delinquent real estate for many counties on one shared calendar, so a single index page can show several counties' parcels and closing dates at once. Read the county name on the lot, not the page it came from, then confirm the venue in the Wisconsin county directory.
Step 6: The floor is appraised value, then it is anything
On the first attempt to sell a parcel, every bid below the appraised value must be rejected. Appraised value is whatever the county board, its committee, or a certified appraiser sets. It is neither the assessed value nor the unpaid tax, so the floor can sit well above or below what was owed.
After that first offering the county may sell for any amount, subject to a further class 1 notice and, where the price falls below appraised value, approval by the board or its committee. Accepting less than the highest bid also requires a written statement open to public inspection. Patience pays on that ladder, so price the parcel with the tax deed max bid calculator before you fill in a bid form.
Step 7: Deposits are county rules and the high bid is only a proposal
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.Payment terms come from the same place, no statute fixes a deadline for the balance, and the award is rarely immediate. St. Croix County opens sealed bids at a public hearing of its Tax Deed Committee, then routes them to the Administration Committee; Oconto County takes its online auction results to that body's monthly meeting. A high bid is only a proposal until a committee votes.
Owner-occupied houses carry a second contingency. For single-family owner-occupied property the board must by ordinance let the former owner or their heirs buy the land back first, and such a sale is exempt from s. 75.69 altogether. Dane County allows 60 days from delivery of the treasurer's certified-mail notice. Treat that house as provisional until the window closes, and run the parcel through due diligence before a tax sale first.
What a Wisconsin tax deed does not wash off
Section 75.14(4) keeps valid restrictions and covenants running with the land alive through a tax deed, enforceable to the same extent they would be against a voluntary grantee of the prior owner. Use restrictions, building type and location, nuisance covenants and covenants to contribute to private road maintenance all survive. Covenants creating a debt or a lien do not, with narrow carve-outs for keeping the premises sightly, road costs and abating nuisances.
A covenant search belongs in pricing, not closing. Read what survives a tax deed and quiet title after a tax deed before budgeting a resale.
Where the surplus goes
Wisconsin sends the overage back to the former owner and makes the treasurer go find them: on taking the deed the treasurer notifies that person by certified mail that a share of future proceeds may be owed. After the sale the treasurer subtracts foreclosure, legal, advertising, title insurance, clean-up and demolition costs, broker fees and every unpaid tax and charge, pays the special assessments owed to taxing jurisdictions, and sends the rest to the former owner. Anything unclaimed 12 months after mailing becomes unclaimed funds, with no interest. Tax deed surplus funds covers how other states handle it.
Buying what nobody bid on
Wisconsin runs no statewide over-the-counter program and keeps no state-held list. County inventory simply stays on the market. Section 75.35(2)(am) lets a board sell its tax-deeded lands on whatever terms it sets, s. 75.35(2)(d) lets it hire licensed brokers, and s. 75.69(1) accepts a multiple listing service posting as the advertisement, so a parcel can sit on the open market until someone buys it. Ask the treasurer or land committee for the list of unsold parcels and make a written offer, but approval runs through the board, so nothing closes across a counter the same day. Over-the-counter tax liens covers the idea elsewhere.
Putting it together
Wisconsin pays an investor nothing to wait, so the whole return sits in the price. Three things decide a bid. Appraised value sets the floor on the first offering and bears no fixed relationship to the tax owed. A committee, not an auctioneer, decides whether you bought anything. And the covenants survive, which can separate a buildable lot from a yard. Watch the class 2 notice for what is coming, track each county's own sale page rather than the shared auction calendar, and treat every owner-occupied house as provisional.
