Wisconsin State law requires that municipalities conduct revaluation of properties to ensure accurate assessments and fair property taxation. The City of West Allis is obligated to conduct a comprehensive assessment of properties since this hasn't been done since 2013. Given the changes in the economy and real estate market over the past 11 years, many assessments will likely be adjusted. 

Property owners whose assessments have changed will be notified via mail beginning April 19. If you receive a notice of assessment and wish to discuss the changes, contact the Assessor to set up an appointment between May 6–10. This is your opportunity to provide more information to the Assessor to make sure your assessment is accurate.  

You also have the right to file a formal appeal with the City’s Board of Review. The board will meet on May 22 at 10 a.m. 

Your participation and cooperation in the process are both necessary and greatly appreciated. Objections to your assessment must be done during this time period and will not be considered at any other time. 

The state mandates that the City of West Allis perform this revaluation. If we do not comply, we may be subject to penalties. Keep reading to learn more.

To Appeal Your Assessment

Please note the time to appeal the 2024 Assessed value has passed and it can no longer be changed.  To request a review of the 2025 assessed value please complete the Property Assessment Request for Review.

Informal Review

There are a few steps to begin the process to appeal your assessment. First, you’ll want to review your property record and file.

1. Click here to view your Property Record Card (i.e., your sales history, square footage, room count and sizes). Enter your address then click on the "Property Record Card" button.

2. Click here to view your Property File (i.e., permits, occupancies, surveys) and click on the "Search" button located in the upper right corner. Type in your address and select it from the dropdown list.

Minor errors and misunderstandings can often be corrected by the assessor instead of making a formal appeal. If you find an error on your property record you can submit a Request for Review asking Assessor staff to review your property record for any minor errors and staff will look at your record and any information you provide.

After review of the property record, staff will inform you of any changes that may be warranted.

Formal Review

If you are not satisfied with the results of the property review, you can file a formal appeal with the 2025 Board of Review.

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.

The Board of Review schedule for 2025 has not been set, but will likely be scheduled in May or June.

To file a formal appeal, you must:

• Provide the City Clerk with written or oral notice of intent to file an objection. mailto:clerk@westalliswi.gov or call 414-302-8220.

• Next, file a completed, written, and signed Objection Form to Real Property Assessment with clerk. 

• Review additional Appeal information  

Under Wisconsin law, generally, the assessor may not change the assessment of property based solely on the recent arm's length sale of the property without adjusting the assessed value of comparable properties in the same market area. For information on the assessment of properties that have recently sold, visit the Internet site of the Department of Revenue.

Assessor's office: Services Provided 

The City of West Allis Assessor’s Office is responsible for the maintenance of ownership information, 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. It is our primary responsibility to provide uniform property values so that the burden of taxes is distributed as fairly and equitably as possible under current law.

Though assessed values are used to calculate tax bills, a change in assessed value does not necessarily equate to an increase or decrease in a tax bill. It is important to note that the overall tax burden is a function of the tax levy approved by taxing jurisdictions whereas the assessed value is a marker for the share of that burden. Property owners may see an increase in assessed value if new construction occurred or new improvements were made to the property. 

To be clear, the amount a property owner will pay on the tax bill is primarily determined by the tax levy. The tax levy is set by the various taxing jurisdictions including the City of West Allis, West Allis/West Milwaukee School District, Metropolitan Milwaukee Sewage District (MMSD), Milwaukee Area Technical College (MATC), Milwaukee County, and the State of Wisconsin.

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.
