2019 Tax Pre-Payment Information 

Under state law (section 7413, Wisconsin Statutes), general property taxes, special assessments, special charges and special taxes may be paid in advance of the levy during the period from August 1 until the third Monday in December each year. This means:

  • Pre-payment of 2018 taxes was allowed from August 1, 2018 to December 17, 2018.
  • Pre-payment of 2019 taxes may be made from August 1, 2019 to December 16, 2019.

Property owners cannot pre-pay December 2019 taxes at this time. There is one exception: businesses ceasing operation may pre-pay personal property taxes on a commercial business any time before December 16, 2019 in the year it ceases.
