Statewide Residential Benchmark
A broad statewide benchmark for Wisconsin is an effective property tax rate of about 1.76% of home value. On a $400,000 residential property, that equals about $7,040 per year. This is a statewide comparison point, not a guarantee of what any parcel will owe.
Basic statewide deadlines
Wisconsin appeal windows move fast
Wisconsin Open Book and Board of Review periods are set locally, often in spring, and the notice controls the appeal window.
Start by checking your Notice of Valuation and gathering your county property record.
Then confirm the current year’s instructions with your county assessor, local board, municipality, or state tax authority, especially if a deadline falls on a weekend or legal holiday.
