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.

The assessment represents the assessable value of the property rather than its full market value.

Should you have any questions regarding the change in assessed value, the Assessor will be available from May 14 to May 16, 2018 in the Assessor's Office, from 9:00 a.m. to 4:00 p.m., BY APPOINTMENT ONLY.  Appointments with the Assessor should be made by calling 414-302-8230.

If after speaking with a member of the assessment staff, you still do not agree with your assessment, you can file an “Intent to Object” form with the City Clerk’s office to appear before the Board of Review. This form needs to be filed at least 48 hours prior to the first meeting of the Board of Review.  Also, a formal objection form must be filed with the City Clerk within the first 2 hours of the first meeting of the Board of Review. The Board of Review will meet at City Hall on Thursday, May 24, 2018 at 9:00 A.M.

The Board of Review operates similarly to a court of law. Its function is not one of valuation, but of determining the validity of the facts presented before it. You or your representative may provide testimony to the Board in objection to your assessment.  You must be able to prove that your assessment is inequitable, or is too high compared to the general level of assessment in West Allis.




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
  • March 1: Last day to file property tax exemption request 
  • March 1: Last day to file personal property returns
  • 2nd Monday in May: Board of Review meets. Will adjourn to a future date if Assessment roll isn't complete 
  • December: Tax bills are calculated and mailed.
