As the April 15 tax filing deadline approaches, we want to bring to your attention a critical change in United States Postal Service (USPS) procedures that affects how postmark dates are applied. This change is vital for anyone mailing tax returns, payments, or other time-sensitive documents.
What Has Changed?
The USPS has revised its postmarking process. Previously, mail was often postmarked with the date it was deposited at a local post office or in a mailbox. Under the new system, the postmark date will generally reflect the date the mail is first processed at a regional USPS sorting facility.
This means the postmark on your envelope could be one or more days after the date you mailed it.
Why This Is Critical for Your Tax Filings
Federal and state tax authorities rely on the postmark date to determine if a tax return or payment is filed on time. The long-standing “timely mailed, timely filed” rule depends entirely on the postmark.
With this new USPS procedure, a return or payment that you mail on or just before the tax deadline could receive a postmark dated after the due date. This would cause your filing to be considered late, potentially resulting in late-filing penalties, late-payment penalties, and interest charges.
Recommendations for a Timely and Secure Filing
To protect you from the risks associated with these new mailing procedures, we strongly advise the following:
- Use Electronic Filing and Payment: The most secure and reliable way to file your taxes and pay any balance due is electronically. E-filing and electronic payments provide an official, dated confirmation of submission, eliminating any uncertainty related to mail delivery and postmarks. We encourage using this method whenever possible.
- If You Must Mail Documents: If mailing is your only option, you can no longer rely on dropping your envelope into a standard mailbox to ensure a timely postmark. To obtain proof of timely mailing, you must take your documents to a post office retail counter and use one of the following services:
- Certified Mail or Registered Mail: These services provide a mailing receipt postmarked by a postal employee and serve as official proof of the mailing date.
- Request a Hand-Stamped Postmark: When mailing at the post office counter, you can ask the clerk to hand-cancel your envelope with a postmark showing that day’s date.
- Use an IRS-Approved Private Delivery Service: Certain services from private carriers like UPS and FedEx are designated by the IRS as valid alternatives to USPS for timely filing.
Please do not assume that dropping your tax documents in a USPS collection box on the due date will be sufficient to avoid penalties.
