How to Submit Your Itin Application by Mail or in Person

by

Applying for an Individual Taxpayer Identification Number (ITIN) is an important step for individuals who need to comply with U.S. tax laws but are not eligible for a Social Security Number. You can submit your ITIN application either by mail or in person at an IRS Taxpayer Assistance Center.

Preparing Your Application

Before submitting your application, ensure you have completed the IRS Form W-7, Application for IRS Individual Taxpayer Identification Number. Gather the necessary documents, including:

  • Original valid passport or other qualifying identification documents
  • Supporting documents that verify your identity and foreign status
  • Tax return, if applicable

Submitting Your ITIN Application by Mail

To apply by mail, send your completed Form W-7, along with the original documents or certified copies, to the IRS address listed in the Form W-7 instructions. It is recommended to send your application via certified mail with a tracking number for security.

Include your tax return if you are applying for an ITIN to file your taxes. The IRS will process your application and send your ITIN by mail within approximately 7 weeks.

Applying in Person at an IRS Office

You can also apply in person at an IRS Taxpayer Assistance Center (TAC). This option allows you to present your documents directly to an IRS representative, who can verify your identity and certify your documents on the spot. This process often results in faster processing times.

Before visiting, check if your local IRS office accepts walk-in appointments or requires an appointment. Be sure to bring all necessary original documents or certified copies.

Additional Tips

Always double-check the IRS website or contact the IRS directly for the latest instructions and mailing addresses. Keep copies of all documents you send, and consider using a secure mailing method. Patience is key, as processing times can vary depending on the volume of applications.

By following these steps, you can efficiently submit your ITIN application either by mail or in person, ensuring compliance with U.S. tax regulations.
