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.

Open Book Review Period

Every year, the assessor's office prepares a preliminary assessment roll. This reflects property values as of January 1 each year.

The Open Book review period is set aside to answer questions posed by property owners and to correct obvious clerical errors that were made in compiling the assessment roll.

This year's Open Book is May 4 - 15, 2020.

Roughly 4% of Wauwatosa property owners will receive a change of assessment notice.

Learn more about the Open Book Review Period.

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.
