U.S. Postal Service Delays

Under state law, if payments are not timely due solely to a U.S Postal Service delay or administrative error, the payments must be considered timely. (sec. 74.69(2), Wis. Stats.)

Property Owner

Any person required to pay interest or penalty due to a late payment can file a written request with the County Treasurer. (sec. 74.69(3), Wis. Stats.)

Written request must:

  • Be filed within 10 days of the interest or penalty payment, but no later than December 1, 2019
  • Ask the County Board to determine the payment is timely since the sole reason the payment was late was due to a U.S. Postal Service delay or administrative error

County Board


  • Act on the request within 30 days of receipt by the County Treasurer
  • Find the payment timely if the payment was late solely due to a U.S. Postal Service delay or administrative error
  • If the payment is deemed timely – County Board will direct the municipality (or county) that collected the payment, to reimburse the taxpayer the interest or penalty payment within 10 days
