Assessor's Office

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.

2023 Wisconsin Act 12

2023 Wisconsin Act 12 exempts personal property from taxation beginning with assessments as of Jan. 1, 2024.  No forms were sent out this year because no reporting of personal property is necessary.

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.
