After you file

If you have successfully e-filed your return and it has been accepted, they have it and won't ask for it again.   

For added peace of mind, you can buy a Certificate of Mailing at the Post Office. A Certificate of Mailing is a proof of mailing receipt that proves you mailed your tax return (or Forms 8949 and 8453)  on a certain date.

After you send your taxes, keep your receipt in a safe place. The Postal Service® does not keep copies of receipts. If your return is delayed or lost, the postmark will not be available, but your Certificate of Mailing receipt will prove that you mailed your return on time.

Certificate of Mailing Service

The Treasury Department and the IRS are providing special relief to all taxpayers and businesses in response to the COVID-19 Outbreak: Tax Day has been moved from April 15 to July 15, 2020.    All taxpayers and businesses will have this additional time to file and make payments without interest or penalties.

See full details about the filing and payment deadline on the IRS website.

Mailing Tips

• Send to the Correct Address
  Check the IRS website for where to mail your tax return. Write both the destination and return addresses clearly or print your mailing label and postage.
  Where to Send Paper Tax Returns
• Use Correct Postage
  Weigh your envelope and apply the right amount of postage. Most tax returns are several pages long and weigh more than 1 oz. Tax returns sent without enough postage will be returned.
• Meet the Postmark Deadline
  If your tax return is postmarked by the filing date deadline, the IRS considers it on time. Mail your return in a USPS blue collection box or at a Postal location that has a pickup time before the deadline. Some Post Office™ locations offer extended hours and late postmarking for tax filers. Call a Post Office near you to find out if it will be open late on tax day.
