Annual Assessment Summary Report

The Wisconsin Department of Revenue (DOR) launched a new Annual Assessment Summary Report today, April 8, 2020. The report's primary function is to provide local government officials a summary of assessment information for their communities; Wisconsin property owners should find the information helpful as card.

Report Information

This report captures information Wisconsin municipalities and counties provide to DOR annually. For example, 2020 assessment information appears on the report after an assessor submits a Municipal Assessment Report and the clerk submits a Statement of Assessment to DOR.

Access/view report

Each report includes

  • General Information – including: assessment year, county-municipality, and Municipal Assessment Report type/date filed
  • Assessor Information – contact information
  • Fast Facts – total assessed and equalized values, and net new construction for assessment year and prior year
  • Parcel County by Class – number of parcels in each class (class 1–7) for assessment year and prior year
  • Real Estate Sales – valid, invalid and total sales for two years prior to assessment year
  • Assessment Level and Type – for assessment year and four prior years
  • Additional Information – helpful resources, including Wisconsin Assessors list and DOR contact information

We want to hear from you – DOR is encouraging local officials to provide feedback on this new report. Let us know if you have suggestions on improving the report for 2021. Contact us at
