Property records in Wisconsin are maintained at the county level. The Municipal Assessor handles property valuations and assessment data. The Municipal/County Treasurer handles tax bills and payments. These are separate offices with separate databases.
What this page covers: Wisconsin property assessment lookups, tax record searches, and parcel/ownership data. What it does not cover: Recorded documents like deeds and mortgages (those are on the Recorded Documents page) or property transfer history.
Where to start: For property values and tax assessments, start with the Municipal Assessor. For tax payment history and bills, go to the Municipal/County Treasurer. For ownership verification, you may need both the assessment records and the recorded documents.
Common mistake: Property assessment records (values and taxes) and recorded documents (deeds and liens) are maintained by different offices in Wisconsin. The Municipal Assessor handles assessments; the Register of Deeds handles recordings. Search both if you need the full picture.

Frequently Asked Questions
Where do I search Wisconsin property records?▼
In Wisconsin, property records — including parcel data, assessed value, deeds, and tax history — are primarily maintained at the county level by each county's Assessor and Recorder. Statewide oversight and reporting are provided by the Official Wisconsin Property Records at www.revenue.wi.gov. See the cards below or the county page for direct local search links.
Is there a free statewide Wisconsin property search?▼
Wisconsin does not have a single statewide free property search; deed and assessment data are searched at the county level. The Official Wisconsin Property Records publishes statewide property-tax rules and aggregate data at www.revenue.wi.gov; for individual parcels, use the county assessor or recorder.
What's the difference between the Assessor and the Recorder in Wisconsin?▼
The county Assessor determines property values for tax purposes and maintains the parcel roll. The county Recorder (sometimes Clerk-Recorder) records deeds, mortgages, liens, and other instruments affecting title. In some Wisconsin countys these are combined offices; in others they're separate. The Official Wisconsin Property Records at www.revenue.wi.gov publishes the full list.
How do I find a Wisconsin parcel ID (APN/PIN)?▼
Parcel identification numbers (APN, PIN, or parcel number depending on the county) are assigned by the county assessor. They appear on every tax bill and on the county's online property-search interface. Once you have the parcel ID you can look up assessed value, ownership history, and recorded documents through the county site; the statewide overview is at www.revenue.wi.gov.
How do I challenge a Wisconsin property assessment?▼
Assessment appeals in Wisconsin are filed at the county level with the local assessment appeals board, typically within a deadline set after annual valuation notices are mailed. The Official Wisconsin Property Records publishes the statewide rules, deadlines, and appeal forms at www.revenue.wi.gov.
