County Treasurer advises USPS policy change on postmarks may affect tax payments


Ozaukee County Treasurer Sandi Tretow is encouraging residents who pay their property tax bills by mail to 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, Tretow said. Instead of postmarks being affixed when the item is first touched by the Postal Service, postmarks are now stamped at regional sorting centers. “That means your postmark could be several days after you put it in your mailbox,” Tretow said. “In other words, if you plan to pay your property taxes by mail, don’t wait until right before the deadline to put it in the mail.”

Tretow noted that many federal and state laws define timely payment based off the USPS postmark, meaning payments may be considered delinquent if they are mailed too close to the deadline — even if they were, in fact, placed in a mailbox before the deadline. To avoid this issue, Tretow encourages Ozaukee County property taxpayers to mail payments earlier, or to pay online to avoid becoming delinquent and accruing substantial late fees. “While Credit/Debit card payments and E-checks come with a service fee, it could be a great option for people who are concerned that they are mailing their payment too close to the deadline and want to make sure that they are not going delinquent.”

Dog & cat licenses are available at City Hall.  Licenses are required annually and are valid January 1 – December 31.  Bring in or mail the rabies certificate(s) and fee(s) to the Treasurer’s Office at City Hall.  The rabies certificates will be returned with the license.  If mailed, include a self-addressed stamped envelope.

Fees: Dog or Cat $10, spayed or neutered dog or cat $5

Licenses must be renewed by March 31, 2026.  After this date, a late fee applies.

Please contact the City Treasurer’s Office at 262-375-7600 with your questions.
