The status of all mailed payments is determined by the post mark on the envelope. If a payment is post marked within the date allowed for timely payment, it is not considered delinquent. If a payment bears a private postal meter stamp and is subsequently over-stamped by the U.S. Postal Service with a later post marked date, the U.S.P.S. post mark is considered the date mailed. If an envelope bears no post mark date, it must be received no later than the deadline date to be considered timely. All mail post marked after the deadline date is considered delinquent and interest is charged from the original due date through and including the month of the postmark. A partial month is considered a full month for interest calculations.
