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.
