Property Taxes in Wisconsin: Rates, Exemptions, and How They Work (2026)
TL;DR
Wisconsin has among the highest property taxes in the Midwest, with an average effective rate of about 1.51%. Property is assessed at 100% of full value. The state provides a Lottery and Gaming Credit and School Levy Tax Credit that appear on your tax bill as direct reductions. Wisconsin does not have a traditional homestead exemption, but the Homestead Credit on state income tax returns provides relief for lower-income homeowners. Appeal through the Open Book period, then the Board of Review, with deadlines in the spring.
Assessment
Wisconsin assesses property at 100% of full market value. Local assessors handle the valuation, with the state Department of Revenue monitoring assessment levels and ordering reassessments when a municipality's assessment ratio falls below 90% or above 110% of full value.
Tax Credits on Your Bill
- Lottery and Gaming Credit: Applied to primary residences. Amount varies annually (typically $100-$200).
- School Levy Tax Credit: Applied to all taxable property. Funded by state revenues.
- First Dollar Credit: Applied to all improved parcels based on a per-acre amount set annually.
Homestead Credit
Wisconsin's Homestead Credit is claimed on your state income tax return, not on your property tax bill. It provides up to $1,168 for homeowners with household income under $24,680. The credit reduces as income increases.
Appeal Process
- Open Book: Assessor makes records available for review (typically April-May). Discuss your assessment informally.
- Board of Review: File a written objection by 48 hours before the Board of Review meets. Present evidence at the hearing.
- Circuit Court: Appeal within 90 days of the Board of Review decision.
Important: You must attend Open Book or have a valid reason for not attending to preserve your right to appear before the Board of Review.
