Assessment Objections

To make an objection to your property assessment you will need to file an objection with the City Clerk to appear before the Board of Review. We recommend that you 1st meet with a member of the assessing staff during the Open Book period in the spring/summer of each year (see calendar for dates).

If after that meeting you still feel your property assessment does not reflect Market Value or it appears inequitable you must file a Formal Objection Form with the City Clerk in order to appear before the Board of Review. Formal Objection Forms will be available in the Assessor’s office during Open Book then afterward in the City Clerk’s Office.

The Board of Review
The Board of Review is a quasi-judicial body that hears formal objections to property assessments. It is a fundamental part the objection process designed so that property owners may express their concerns about the value of their property. The Board of Review is comprised of residents of the City of Sun Prairie appointed by the Mayor.

Board Operations
A Board of Review operates like a court, but isn’t quite as formal. It can hear only sworn oral testimony from you or your official designated representative and from the Assessor. The Board of Review’s function is not one of valuation, but of deciding the validity of the facts presented orally before them. You or your official designated representative may testify concerning your assessment objection. You must prove that your property is inequitably assessed when compared to the general level of assessment within your tax district.

Evidence Needed
The board will consider recent arms-length sales of the subject property or reasonably comparable properties. If you intend to present an appraisal, the board will expect the appraiser to be available for testimony and you have received permission from the client named on the appraisal report. Keep in mind that the assessment date is always January 1st.
