使用 USPS 邮寄您的纳税申报单

Use the U.S. Postal Service® to mail your tax return, get proof that you mailed it, and track its arrival at the IRS.

The IRS considers a tax return filed on time if it is addressed correctly, has enough postage, and is postmarked by the due date.

  • October 15, 2020 – Federal tax return extension deadline for tax year 2019
  • April 15, 2021 – Federal tax return filing deadline for tax year 2020

邮寄提示

  • 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.

邮寄证明

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 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.
