** PROPERTY TAXPAYERS PLEASE TAKE NOTE **
UNITED STATES POSTAL SERVICE (USPS) POLICY CHANGE REGARDING POSTMARKS
If you pay your property taxes by mail, please be aware of a recent U.S. Postal Service policy change that may affect when envelopes are postmarked.
In August 2025, the Postal Service instituted a nationwide change as to when a postmark is affixed to incoming mail. Instead of postmarks being affixed when the item is first touched by the Postal Service, postmarks are now stamped at regional sorting centers. This means that your postmark could be several days after you put it in your mailbox.
For most municipalities in Wisconsin, the due dates for property tax payments are as follows:
First installment: | Due on or before January 31 |
Second installment: | Due on or before July 31 |
Again, if mailing your property tax payment, please ensure you leave enough time for your payment to arrive at a regional sorting center for post mark by the deadline. Simply placing your payment in a mailbox by the deadline may not ensure timely payment.
