Where do you mail 1040x

When filing an amended tax return (Form 1040X), you should mail it to the Internal Revenue Service (IRS) at the following address:

Internal Revenue Service Amended Return Department 1111 Constitution Ave NW Washington, DC 20224-0002

Make sure to use the correct address, as the IRS has different addresses for different types of returns and correspondence.

Here are some additional tips to keep in mind:

  1. Use the correct form: Make sure you're using the correct form, Form 1040X, and that you're completing it correctly.
  2. Attach supporting documents: Attach any supporting documents, such as corrected W-2s or 1099s, to the Form 1040X.
  3. Sign and date the form: Sign and date the Form 1040X in the space provided.
  4. Use the correct postage: Use the correct postage for the weight and size of your envelope.
  5. Keep a copy: Keep a copy of the Form 1040X and supporting documents for your records.

It's also a good idea to use certified mail with return receipt requested to ensure that the IRS receives your amended return and to keep a record of the mailing.

Note: If you're filing electronically, you can use the IRS's e-file system to submit your amended return.
