If you lost a property to a tax sale in Wisconsin, there may be surplus funds sitting in a county account waiting for you to claim them. Every year, counties across the Badger State conduct in rem foreclosure proceedings on tax-delinquent properties, and when those properties sell for more than the outstanding debt, the excess belongs to the former owner. The problem is that most people are never notified.
Wisconsin's surplus funds landscape changed dramatically after the 2023 Supreme Court ruling in Tyler v. Hennepin County. That decision made clear that governments cannot keep excess proceeds from tax sales beyond what is owed, which has forced Wisconsin counties to be more transparent about the money they hold. If you previously lost a property and assumed the money was gone, now is the time to take a closer look.
How Wisconsin Tax Sales and In Rem Foreclosure Work
Wisconsin uses an in rem foreclosure process rather than a traditional auction-style tax sale. When a property owner falls behind on property taxes for several years, the county can initiate a foreclosure action against the property itself. Once the court grants the foreclosure, the county takes title to the property and can sell it on the open market or at a public sale.
If the county sells the property for more than the total amount of delinquent taxes, interest, penalties, and costs, the difference is surplus funds. For example, if a property owed eight thousand dollars in back taxes but the county sold it for fifty thousand dollars, the remaining forty-two thousand dollars is surplus that should be returned to the former owner.
In Wisconsin, the County Treasurer is the office responsible for managing tax-delinquent properties and holding any surplus funds that result from these sales. Each county operates independently, so the process and timelines can vary from one jurisdiction to the next.
The Tyler v. Hennepin Impact on Wisconsin
The Supreme Court's unanimous ruling in Tyler v. Hennepin County established that keeping surplus proceeds from a tax foreclosure sale violates the Fifth Amendment's Takings Clause. While the case originated in Minnesota, its impact has rippled across every state that conducts tax sales, including Wisconsin.
Before this ruling, many Wisconsin counties kept the full sale price of foreclosed properties regardless of how much was actually owed in taxes. Former owners had little practical recourse. Now, counties are required to account for and return surplus funds to the rightful owners. This means there may be money owed to you from sales that happened years ago, not just recent ones.
Key Wisconsin Counties With Surplus Fund Activity
Milwaukee County is by far the most active county in Wisconsin for tax foreclosures. With the highest population in the state and a significant number of tax-delinquent properties, Milwaukee produces more surplus funds than any other county. The County Treasurer's office handles claims and can be contacted directly for information about excess proceeds.
Dane County, which includes the state capital of Madison, is another major source of surplus funds. Dane County has published surplus fund information on its website, making it one of the easier counties to search. Rising property values in the Madison area mean that foreclosed properties often sell for well above the tax debt.
Waukesha County sits just west of Milwaukee and has some of the highest property values in Wisconsin. Tax foreclosures in Waukesha tend to generate significant surplus amounts because of the strong real estate market. The County Treasurer's office manages these funds and responds to inquiries from former owners.
Other counties worth checking include Brown County (Green Bay) and Racine County, both of which conduct regular foreclosure sales and hold surplus funds. If you owned property anywhere in Wisconsin, it is worth investigating whether excess proceeds exist.
How to Search for Your Wisconsin Surplus Funds
Because Wisconsin handles surplus funds at the county level, there is no single statewide database to search. You need to contact or check with the County Treasurer's office in the county where your property was located. Gather any documents you have related to the property, including old tax bills, the parcel number, the property address, and the approximate year the foreclosure took place.
Some counties publish surplus fund lists on their official websites, while others require you to call or submit a written request. When you contact the county, ask specifically about excess proceeds from the sale of your former property. Be prepared to provide identification and proof of your ownership at the time of foreclosure.
Be cautious if a third-party company contacts you about surplus funds. While some recovery firms are legitimate, others charge excessive fees. Before signing any agreement, understand your options for filing a claim on your own. This article is for informational purposes only and is not legal advice.
