City of Port Washington Assessor

Services Provided

The Assessor discovers, lists, and establishes uniform values on all taxable property. Our goal is to ensure that the property tax burden is distributed fairly among all property owners. To accomplish this, we revalue all property as needed. The last city-wide revaluation took place in 2012. In addition, we serve as an informational resource to the community.

Basis For Assessed Values

Wisconsin law requires that all assessments be based on fair market value. The Assessor does not create value but interprets what is happening in the marketplace. WI Statutes 70.32 explains how real estate is valued for assessment purposes. A change in an assessed value does not automatically mean a change in property taxes. Helpful publications are available by clicking on the links below. If you disagree with your assessment, you may contact our office and we will review it for 2016, if you have evidence of market value.
