How Wauwatosa is Prepared to Respond to COVID-19

Wauwatosa routinely plans, trains, and exercises with partner agencies on responses to pandemics or infectious diseases. We are monitoring developments related to COVID-19 as they happen. Learn about city services available online or by mail.


What we do

We appraise or value real and personal property at fair market value for tax purposes. We do not set or collect taxes. We handle three major duties:

  • to discover
  • to list
  • to value all taxable property within Wauwatosa

Contact us with questions about a property, property assessments, or related topics. You can also use the Property Search tool to research properties.

Revaluation Year

In 2019, our Assessor’s Office completed a revaluation. This is a city-wide review of all property assessments. We make value adjustments where necessary to guarantee that all property is assessed at market value. This ensures that taxes are distributed equitably. Learn more about the revaluation: how this affects property owners, how you can participate, and what to do if you have questions.

Once the assessment roll affidavit is signed, values can only be changed by the local Board of Review, an appeal to the Wisconsin Department of Revenue, or through litigation.


Assessed values are established as of January 1 according Chapter 70 of the Wisconsin Statutes, and each tax assessment is absolute.
