Making the Decision to File an Appeal

  • Allow the Assessor's office staff to view your property before you decide whether to appeal your assessment by using the property review request form. Sometimes a formal hearing before the Board of Review can be avoided by meeting our Assessor's staff first.    
  • The best indicator of market value is a recent arm's length sale of the subject property.
  • Actual sales of comparable properties are the next best suitable evidence of the value of the subject property.
  • If, after meeting with the Assessor's staff, you are still unsatisfied with your property's assessment, complete and file an objection form with the City Clerk's office.
  • The Agent Authorization form is also available online or in paper form at the City Clerk's office. 

2020 Board of Review Schedule

The first meeting of the Board of Review is May 29, 2020. No cases will be heard on this date, as the first meeting is to determine Board of Review logistics.

About the Hearing

  • You will receive written notice of the date and time of your hearing before the Board.
  • You will be asked to provide a copy, before your hearing, of the documents you will be presenting to the Board during your hearing.
  • If you submit an appraisal, the appraiser must be present at the hearing for follow-up questioning.
  • You will have the opportunity to question the assessor.
  • Per state statute, the assessed value is presumed to be correct; it is your responsibility to prove that the property is over-assessed in comparison with similar property in Wauwatosa. You should have considerable information that is relevant to the market value of your property. This may include a recent arm's length sale of your property, or recent sales of comparable properties
  • The Wisconsin Department of Revenue has a Guide for Property Owners that contains more information.

Steps to File a Formal Objection

  • To file a formal appeal, give notice of your intent (through this written notice of intent or by calling the City Clerk's office at 414-479-8917) at least 48 hours before the Board of Review begins.
  • You must also complete the Real Property Assessment Objection form or the Personal Property Assessment Objection form. The form must be filed before or during the first two hours of the Board of Review's first meeting.
  • Objections may proceed to a formal hearing before the Board of Review and are typically held after the second Monday in May. Similar to a court, the Board of Review has the responsibility for resolving differences of opinion of valuation. The Board of Review hears oral testimony and evidence presented by the property owner and the Assessor's staff. After hearing the evidence, the Board of Review may lower, raise, or sustain the assessment.
