Kenosha County Treasurer Teri Jacobson 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, Jacobson 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,” Jacobson
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.”
Jacobson 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, Jacobson encourages Kenosha County property taxpayers to mail payments
earlier or to use the E-check option to pay online to avoid becoming delinquent and accruing
substantial late fees.
“While Credit/Debit card payments often come with a significant 3 percent convenience fee, E-
check convenience fees for tax payments made on the county web site are a flat $1.50 per
payment which comes out to about the same as postage for your payment and a return receipt,”
Jacobson said. “This 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.”
Payments for all municipalities, except the current year City of Kenosha tax payments, can be
made on the County’s website at https://pp-kenosha-co-wi-fb.app.landnav.com/login/ by using
the guest sign in option and searching by either the property address or property/parcel number
1010 56th Street • Kenosha, WI 53140 • Phone: 262-653-2542 • Fax: 262-653-2564
Teri.Jacobson@kenoshacountywi.gov • www.kenoshacounty.org(do not use both). Current year city of Kenosha payments can be made through the city’s
website.
Jacobson cautioned taxpayers about sending tax payments utilizing their personal bank’s online
bill payment option as those payments are often done in bulk with many other customers’
payments, so there is a danger those could arrive late and become delinquent as well. This type
of payment has become even more problematic in recent years as the time it takes for USPS
items to arrive at its destination after mailing has increased, Jacobson added.
Another option could be to physically bring your payment into the post office and request that
they postmark your payment in front of you or by sending it certified mail, Jacobson said.
