USPS Tips for Customers Mailing their Tax Returns –

• Mail early.
• If you are mailing a lot of documents, use a suitable envelope or box. Priority Mail envelopes are available from the lobby of your local post office.
• Be sure to use sufficient postage. Does it weigh more than 1 ounce? Tax returns without enough postage will be returned. If you are unsure about the postage, it’s best to add extra stamps or take your mailpiece to the Post Office to ensure sufficient postage.
• Write clearly. Print labels or neatly write both the destination and return addresses.
• Double check your envelope.
• Customers who wish to validate that their return was received by the IRS, are encouraged to consider proof of mailing services such as Return Receipt, Certified Mail, or Certificate of Mailing Service.
• Avoid the rush. Consider mailing your tax return in a collection box that has a pick-up time before the deadline.

NOTE: The Internal Revenue Service deadline for filing Federal Income taxes will be Monday, April 18, 2016. (The income tax deadline was extended this year in recognition of Emancipation Day. On April 16, 1862, President Abraham Lincoln signed the Compensated Emancipation Act. As the holiday falls on a Saturday this year, it will be observed on Friday, April 15th. Government offices in Washington DC will be closed in honor of Emancipation Day and many public services in DC will be unavailable.)

The Postal Service receives no tax dollars for operating expenses and relies on the sale of postage, products and services to fund it operations.
