Take Notice of USPS's New Postmark Procedure

Important Message
From Your Tax Receiver

Effective December 24, 2025, the United States Postal Service (USPS) has made a change in procedure that affects the timing of “machine” POSTMARKS. The change is that machine postmarks will reflect the date mail is first processed at a regional facility, NOT when dropped in a local mailbox. This change in procedure has the impact of potentially causing delays for time-sensitive mail, like tax payments and other bills/filings where postmarks are used to determine timely receipt. The potential delay can be a 1-3 day gap between mailing and the official postmark. The impact of this action by the USPS on time sensitive items is that it could lead to penalties mandated by law.

Here is what you have to do, if you are close to the deadline of making a tax payment: 

* GO TO THE POST OFFICE COUNTER & REQUEST A HAND-STAMPED POSTMARK

* PAY ON-LINE

* PAY IN PERSON

            Please call our Tax Office at 914-962-5722 x212, if you have any questions.
