New U.S. Postal Service rules could impact taxpayers who mail their returns. Postmarks may now be applied when mail reaches automated processing, not necessarily when it’s dropped off in a mailbox or handed to a carrier. This means your return could be postmarked later than the day you sent it.
Returns postmarked after April 15 are considered late and may incur penalties unless an extension has been filed. E-filing remains the most reliable way to avoid delays. If you plan to mail your return close to the deadline, visit your local post office and request proof of your mailing date.
A quick reminder to plan ahead and avoid last-minute mailing risks as the deadline approaches.
