Assessor's Office
Services Provided

The City of West Allis Assessor’s Office is responsible for the maintenance of property ownership information, a complete description of each property and the valuation of all taxable property within the City in accordance with The Wisconsin Property Assessment Manual and Chapter 70 of the Wisconsin State Statutes.

Assessor's Responsibility
Since 1848 in Wisconsin, "...taxation shall be uniform...", as required under the Preamble to the State Constitution.

It is the Assessor's primary responsibility under case law, statute and our State Consititution to produce equitable and uniform property assessments in order to ensure that the burden of property tax is distributed fairly and equitably among all property owners. 

It makes sense to most people that for property taxes to be considered "fair", similar properties should have a similar tax burden; Overall property assessments should make sense and be consistent with each other.

An easy way to understand this is when comparing homes with one another. The newest, biggest and best home in West Allis should have the highest assessment and the oldest, smallest and most run down house should have the lowest, with all other houses somewhere in between.    

Important Dates in the Assessment Process
  • January 1: All property is assessed as it existed on January 1
