Pay property tax in full or first installment by January 31. Wisconsin real property tax is due January 31, either in full or as the first installment (a bill under $100 must be paid in full), and missing it makes the whole year's unpaid tax delinquent as of February 1, with 1 percent monthly interest plus any local penalty of up to 0.5 percent a month.
Pay the final property tax installment by July 31. If you paid your Wisconsin property tax bill in installments, the last installment is due by July 31 to the treasurer named on your bill (some municipalities set extra or later installment dates, so check it), and missing it makes the whole unpaid balance delinquent with 1 percent monthly interest plus up to 0.5 percent monthly local penalty, charged back to February 1.
