Last days to pay without penalty

A payment due on the first of a month is late if not paid by the first of the next month. Due January 1 means pay by February 1. Once it's late, interest runs from the original due date.

Interest doesn't start until 60 days after the postmark on your bill.

30 days from the date on the 2026 bill. Bills hadn't gone out when we last checked.

Your payment must arrive or be postmarked within 10 calendar days of the due date. After that a 4% penalty is added for one late installment. Two late installments add another 5%, three add another 6%, and all four add 7%.
