Due to recent changes with the United States Postal Service, mail dropped in a post office collection box or taken to a local post office may not receive a postmark the same day. For tax payments, listing forms, and other tax related documents, please be aware of this change. To guarantee a same-day postmark, the USPS recommends taking your mail to a post office retail counter and request a manual (hand-stamped) postmark.
