USPS Postmark Changes
In August of this year, the US Post Office announced a new rule that most letters will no longer be postmarked on the day the letter is received by a post office but instead postmarked when the letter is processed at a regional mail processing facility, which can be 1–2 days later (longer on weekends or holidays).
If you’re mailing something with a deadline:
• Mail early. Sending payments well in advance of the deadline remains the most reliable method.
• Consider in-person or online payments
• Utilize the drop box at City Hall for after-hour payments
Tax payments that are received late will be considered delinquent if postmarked after the due date.
