The final Assessment Roll will be reported to the Finance office for use in preparation of the 2021 Tax Roll and also to the  Wisconsin Department of Revenue Equalization Bureau for use in finalizing the City’s total Equalized Value for 2021.

The Equalized Value is used in shared revenue calculations for the City and each of the four school districts which serve City Residents.

If you would like to request that an appraiser review your property assessment for the 2021 tax year, we would be happy to schedule an interior and exterior inspection at your convenience.
