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 during Open Book hours by appointment. Open Book hours are from 9 A.M. to 4 P.M – TBD in the Assessor’s Office.

To make an appointment please call: 414-302-8232.  


To Appeal your assessment

First, discuss with your local assessor – minor errors and misunderstandings can often be corrected with the assessor instead of making a formal appeal.  Should you have any questions regarding this change in assessed value, please call the Assessor’s Office at 414-302-8232 prior to TBD.

To file a formal appeal – give notice of your intent to appeal by contacting the City Clerk at least 48 hours before the Board of Review begins. Complete and file your Objection to Real or Personal Property Assessment form with the Clerk no later than the first two hours of the Board of Review’s meeting. Make sure you file a completed form or the Board of Review may not review your appeal. You can contact the City Clerk at 414-302-8220 or

The Board of Review will meet at City Hall in the Common Council Chambers on TBD at 10:00 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 the assessment. You must be able to prove that the 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 Constitution 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.


A revaluation of property assessments in the City of West Allis shall occur for the 2019 assessment year. The approximate dates of the revaluation notices being sent to property owners is expected to be in June 2019. Please also notice that the Assessor has certain statutory authority to enter land as described in Sections 943.13 and 943.15, Wisconsin Statutes.

The ability of enter land is subject to several qualifications and limitations, as described within the foregoing statutes. Copies of the applicable statutes can be obtained at public depositories throughout the State of Wisconsin, and from the State of Wisconsin Legislative Reference Bureau website ( or copy may be obtained from the municipal clerk upon payment of applicable copying charges.
