Property-tax appeals in Wisconsin
Deadlines, evidence, and a packet you file yourself — for homes, multifamily, and commercial property in Wisconsin.
State rules verified from public sources| Deadline rule | Municipal Board of Review: give the board clerk written or oral notice of intent to object at least 48 hours before the board first scheduled meeting, and file the written objection within the first 2 hours of that meeting (Wis. Stat. 70.47(7)(a); waivers exist for good cause during the first 2 hours and for extraordinary circumstances up to the end of the session). The board meets annually in the 45-day period beginning the fourth Monday of April, at least 7 days after Open Book closes. |
|---|---|
| First hearing body | Municipal Board of Review; then certiorari review in circuit court (the board written-objection step is a prerequisite — no court may question a valuation that was not objected to before the board). |
Start at Open Book: review the roll and talk to the assessor before the Board of Review convenes. An objector who refused the assessor reasonable certified-mail request to view the property cannot appear or contest the amount (70.47(7)(aa)). Objection forms approved by the Department of Revenue require you to state your own valuation of the property. First-class cities (Milwaukee) run a separate process — check the city instructions.
What wins in Wisconsin
Homes are argued on comparable sales and uniformity. Income property is argued on the income approach — rent roll, expenses, and a supported cap rate. The packet builds the argument that matches your property type, with your evidence organised as exhibits.
