Mail Your Tax Return with USPS


When you mail your taxes with the U.S. Postal Service®, you enjoy the benefits of the “timely mailing as timely filing/paying” rule for tax returns and payments. As long as your return is postmarked by April 15th, the IRS considers your return filed on time.

April 15, 2014

Federal Tax Returns Due! Taxes must be postmarked by this date to qualify for timely filing.

October 15, 2014

Due date for those who filed an extension.

Please be aware that an extension of time to file is NOT an extension of time to pay.

We’ve even extended hours on Tax Day at some Post Office™ locations to make things easier for you. Use our PO Locator tool to see which locations will be open late to postmark your tax return. Partner locations do not offer late postmarking. Please verify their last collection hours to ensure you get your tax return in the mail on time.

Call or visit your local Post Office or postal location if you have additional questions.
