How Milwaukee County Assesses Property
Assessed by: City of Milwaukee Assessor's Office (for City of Milwaukee properties) or respective municipal assessor offices for other cities in Milwaukee County
Assessment cycle: annual
Notices typically mailed: Mid-April
Wisconsin law requires property to be assessed at 100% of its fair market value. In Milwaukee County, the assessed value equals the market value, there is no assessment ratio adjustment. For example, if your home's market value is $207,700 (the county median), your assessed value would be $207,700. At the county's effective tax rate of 1.97%, this results in approximately $4,092 in annual property taxes before any credits or exemptions are applied.
The Appeal Process
Appeals are heard by the Board of Review. After filing your appeal, an assessor will inspect your property and review your evidence. The Board of Review will hold a hearing where you'll have an opportunity to present your case, typically with 5-15 minutes to explain why you believe your assessment is too high.
Step 1: Review your assessment notice carefully when it arrives in mid-April and compare your assessed value to similar properties in your neighborhood and recent sales data.
Step 2: Contact the City of Milwaukee Assessor's Office between the fourth Monday in April and the third Monday in May (April 20-May 18, 2026) to initiate your appeal.
Step 3: Complete and submit the Milwaukee Real Property Appeals application either online through the web portal, by mail, or by hand-delivering it to Room 507 at City Hall. Do not email the form, emailed forms are not accepted.
Step 4: Gather and submit supporting evidence with your appeal, including a current appraisal, comparable sales analysis from a real estate agent, photos showing property condition, or repair estimates documenting needed work.
Step 5: An assessor from the office will be assigned to review your appeal and will schedule a property inspection. Cooperate with the inspection and provide any additional information that supports your case.
Step 6: Attend your Board of Review hearing if scheduled. Present your evidence professionally and be prepared to answer questions about your property's value and condition.
Step 7: If your appeal to the Board of Review is denied or you disagree with the decision, you may file a further appeal with the Wisconsin Department of Revenue under Wis. Stat. Section 70.85.
Step 8: As a final option, if administrative appeals are exhausted, you may appeal your assessment to circuit court following the procedures outlined in Wisconsin state law.
