HOW WISCONSIN APPEALS WORK
THE SHORT VERSION

Wisconsin assesses at the city, village, or town level, not the county. You review your assessment at open book, then file a written objection with your local board of review, after giving 48 hours notice of intent. An appeal helps when sales show your assessment is above market.

WHEN AN APPEAL MAKES SENSE
  • Recent sales show your assessment is above what your home would sell for.
  • The record has an error in your home’s size, condition, or features.
  • You give notice of intent at least 48 hours before the board of review’s first meeting and file your objection in the first two hours.
WHEN IT USUALLY WILL NOT
  • Your bill went up but your assessment is fair. A higher bill often comes from the tax rate, not the assessment.
  • You have no market evidence. The board reviews your home’s value, not the size of your bill.

Read the full explanation

In Wisconsin, your city, village, or town, not the county, assesses your home, and you challenge the value through your local board of review. First you can review your assessment during the open book period, then you file a written objection with the board. You must give the municipal clerk notice of your intent at least 48 hours before the board’s first meeting, and file your objection within the first two hours of that meeting. If the board denies you, you can appeal to circuit court. An appeal helps when sales show your assessment is above market, or the record is wrong. It usually will not help just because your bill went up. This is general information, not tax advice.
