Second tax installment payment due date
Property taxes as levied are collected by local treasurers typically through the last day of January in each year. At this time, a settlement process between the County Treasurer and local treasurers determines the amount due to the various taxing districts. Real property taxes are payable by taxpayers in full by the last day of January or in two installments due by January 31st and July 31st. Personal property taxes are due in full by the last day in January.
Local municipalities can adopt an ordinance for multiple payments. City of Wausau has an ordinance for January 31st, April 30th, and July 31st payments.
Many local treasurers have part-time offices. They mail schedules for office house with tax bills and prefer payments by mail.
