Searching Trempealeau County Treasurer Records
Data available
On the Ascent Real Estate Tax Parcel search, search by parcel ID, street number, or owner first/last name, then open the parcel for tax history and online payment. Annual real estate tax rolls by municipality are also downloadable from the Treasurer Real Estate Tax Rolls page. First-installment current-year payments (Dec–Jan) go to the local municipal treasurer, not the county portal.
Additional Information
The Trempealeau County Treasurer collects second-installment and delinquent property taxes for about 30,000 parcels across 26 municipalities and publishes office hours and contacts at co.trempealeau.wi.us. The public can search parcel tax information for free through the county Ascent LandRecords Real Estate Tax Parcel portal (linked from Pay Your Taxes Online), including tax history and online payment. Municipality tax rolls are available as free PDF documents from the Treasurer Real Estate Tax Rolls page. A legacy Catalis GCS Web Portal still lists parcel search but states its data is no longer updated as of 2025 and points users to Ascent.
