   What to Know About the Board of Review and Section 70.85 in Wisconsin.

  Each year, thousands of Wisconsin homeowners receive their property assessment notices and may feel their valuation is too high. The first opportunity to challenge that valuation is at the local level—through the Board of Review (BOR). But what happens if your case is heard and denied, and you still believe the assessment is unfair?

  That’s where Section 70.85 of the Wisconsin Statutes comes in—a lesser-known, but powerful tool that allows property owners to appeal directly to the Wisconsin Department of Revenue (DOR). Here’s what you should know about how this process works, and how it can make a real difference.

  After the Board of Review
  If you’ve gone through the BOR hearing and your appeal was denied, you may be eligible to file a 70.85 appeal. This statute allows the DOR to step in and review the case if you believe the assessment was excessive and wasn’t corrected at the local level.

  This isn’t a new hearing—there’s no courtroom or testimony. Instead, the DOR’s Equalization Bureau reviews all of the materials that were already presented at the BOR. That includes evidence from both the property owner and the municipality, such as:

  Comparable property sales
  Photos and documentation
  Assessor’s notes and valuation methods
  Independent appraisals, if submitted
  The key thing to understand is that the 70.85 process is record-based. No new information can be introduced. It’s all about how the original case was presented and whether the assessment was supported by the facts.

  The DOR's Role and the Decision Process
  Once a 70.85 is filed (by October 1 of the assessment year), the DOR reviews the complete BOR record. Both the municipality and assessor must also submit their supporting data, and the Equalization team evaluates all the evidence with fresh eyes.

  If they find that the property was overvalued based on that documentation, they can order a revised assessment, which becomes final. This offers homeowners a meaningful opportunity to correct errors—particularly in cases where local officials may have missed or misunderstood critical facts.

  A Real-World Example
  In 2023, a homeowner in Outagamie County filed a 70.85 appeal after the local BOR denied their request to reduce their home’s assessed value. The owner had provided an independent appraisal and examples of similar homes in their neighborhood selling for significantly less. The local board sided with the assessor, arguing the home was in better condition than the comparables used.

  The homeowner proceeded with a 70.85 appeal. After reviewing the materials, the DOR found that the assessor had over-relied on sales from newer properties in a different part of the municipality. The Equalization team concluded that the assessment was 12% too high and ordered a correction, resulting in a reduced tax burden for the homeowner.
