The Sherman County Treasurer is alerting residents and businesses that they should plan ahead when submitting time-sensitive mail following a recent clarification by the United States Postal Service (USPS) regarding postmarking practices.
Under the updated guidance, USPS cannot guarantee that the date it takes possession of a mailpiece will be the date reflected in the postmark. Residents are encouraged to take extra precautions when mailing documents that rely on a postmark to meet statutory or regulatory deadlines. This includes real estate, personal property tax payments, and inheritance tax payments.
Additionally, recent USPS transportation changes may affect how mail moves from local post offices to processing centers. This could further delay when the mail is postmarked.
