About Property Taxes in Wisconsin
Wisconsin property taxes are administered at the municipal level — cities, towns, and villages each have their own assessor. Property is assessed at its full market value (100%) in most municipalities, and the state Department of Revenue monitors assessment quality through annual equalization studies. Wisconsin's property tax bills include several built-in credits that are applied directly to the bill, automatically reducing what you owe. These credits — including the Lottery and Gaming Credit and the First Dollar Credit — are applied without requiring any application from the homeowner.
Payment & Assessment
Wisconsin property taxes are due January 31 in full, or you may pay the first installment by January 31 and the second installment by July 31. Most municipalities allow splitting into two equal payments. Interest of 1% per month applies to late payments. Most municipalities offer online payment, payment by mail, and in-person payment at the municipal office. Some counties also accept payment at the county treasurer's office for delinquent taxes.
