How to mail form 1040

To mail Form 1040, you'll need to follow these steps:

  1. Make sure you're using the correct address: The IRS has different mailing addresses depending on where you live. You can find the correct address on the IRS website or on the back of your tax return.
  2. Use the correct envelope: Use a large, flat envelope that is at least 9 1/2 inches wide and 12 1/2 inches long. You can purchase these envelopes at a post office or office supply store.
  3. Attach the correct postage: Make sure you have the correct postage for the weight and size of your envelope. You can use a postage scale or consult with a postal worker to determine the correct postage.
  4. Include all required documents: Make sure you include all required documents, such as:
    • Your completed Form 1040
    • Any supporting schedules and forms (e.g. W-2, 1099, etc.)
    • Any payment vouchers or checks (if you're paying by check)
  5. Use a secure and trackable mailing method: Consider using a secure and trackable mailing method, such as certified mail or priority mail with tracking. This will help ensure that your return is delivered to the IRS and can be tracked in case of any issues.
  6. Keep a copy for your records: Keep a copy of your completed tax return and all supporting documents for your records. This will help you in case you need to refer to your return or provide documentation to the IRS.
