Taxpayers who plan to mail their 2025 federal or state tax returns are facing new challenges due to ongoing U.S. Postal Service (USPS) operational changes. The Oregon Department of Revenue has advised paper filers to mail their returns by April 9—six days before the official April 15 deadline—to ensure timely postmarking and avoid late-filing penalties.
Core Facts & Immediate Action
The IRS considers a tax return filed on time if it is postmarked by the deadline. However, USPS delays in processing mail mean returns mailed close to April 15 may not receive a postmark until after the deadline. Oregon officials recommend mailing returns by April 9 to account for these delays. Electronic filers remain unaffected and can submit returns up to April 15 without risk.
Deeper Dive & Context
Why Postmarking Delays Matter
USPS has been undergoing a multiyear overhaul, including reduced mail pickups and consolidated processing facilities. A December 2024 Federal Register rule clarified that postmark dates may not align with the date mail is accepted, as processing delays can occur before postmarks are applied. While USPS maintains that postmarking methods have not changed, the agency acknowledges that mail may take longer to reach processing centers where postmarks are applied.
Options for Late Filers
Taxpayers who cannot mail returns by April 9 can visit a USPS counter in person by April 15 to request a manual, hand-canceled postmark. Electronic filers receive refunds faster, with an average processing time of two weeks for direct deposits.
Broader Implications
The warning primarily affects the 6% of Americans who file paper returns, as electronic filers are unaffected. The IRS has not issued a nationwide advisory but has historically relied on postmark dates for timely filings. Tax experts caution that delays could lead to penalties or interest for those who owe money.
