Mail Your Tax Return with USPS
Use the Postal Service® to file with confidence on tax day. Find the right products and services to fit your tax day needs.
Federal Tax Deadlines
If your return is postmarked by April 15th, the IRS considers it filed on time.
April 15, 2015 – Federal tax return filing deadline.
October 15, 2015 – Federal tax return extension deadline.
Use PO Locator to find locations that will be open late to postmark your tax return. Partner locations that provide postal services do not offer late postmarking, so verify their last collection hours.
- Be sure to use sufficient postage. Double-check your envelope. Does it weigh more than 1 oz? Tax returns without enough postage will be returned.
- Write clearly. Print labels on your computer or neatly write both the destination and return addresses.
- Avoid the rush at the Post Office. Mail your return in a Collection Box® that has a pick up time before the deadline.
