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 well​.

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
