The Real Property Lister is responsible for the county's real property listing and associated assessment functions, supplying parcel-based land information to both land information professionals and to the general public.
NOVUS is the county's online tax, property, and assessment information database.
Although provided for by statute, no county in Wisconsin operates a County Assessor Office. Property valuation is handled at the local level. However in Wisconsin the County Real Property Lister maintains a substantial amount of property information at the county level. Find your assessor.
For information on appealing your assessment there is an assessment appeal guide (PDF) from the Wisconsin Department of Revenue.
AssessorData.org is an external website that hosts some basic assessment information.
