The county mails one tax statement a year, by March 15, and does not mail another before the April or October deadline unless you ask for one.

The Treasurer says that when a due date falls on a weekend or holiday, payment is due the next business day, which is Monday, November 2, 2026. Paying by Friday, October 30 avoids any question.
