2020 Property Assessments

The COVID-19 Public Health Emergency will not impact 2020 property assessments.  State law (sec. 70.10, Wis. Stats.), provides the annual assessment date of January 1. The 2020 assessments are effective as of January 1, 2020 and are based on the property's status as of January 1, 2020.

The Wisconsin Department of Revenue provided special guidelines for Property Assessment and Taxation for the 2020 revaluation.  This information was emailed on March 25, 2020 to Certified Assessors, the Assessor list, Municipal Clerks, Municipal Treasurers County Clerks and Treasurers, Real Property Listers and Register of Deeds offices.

The  Milwaukee Assessor’s office will follow these guidelines for the 2020 assessment cycle.
