What is an ITIN?

An Individual Taxpayer Identification Number (ITIN) is issued by the IRS to individuals who are not eligible for a Social Security Number but need to file taxes. ITINs allow immigrant families to comply with tax laws, claim credits, and receive refunds.

Form W‑7 Overview

  • ITIN applications are filed using Form W‑7.

  • Must be submitted with a valid federal tax return (unless exceptions apply).

  • Requires proof of identity and foreign status.

 

Acceptable Documents

To apply or renew, families must provide original or certified copies of documents such as:

  • Passport (most common)

  • National ID card

  • Birth certificate (for dependents)

  • U.S. visa or immigration documents

 

Renewal Timelines

  • ITINs not used on a tax return for three consecutive years expire.

  • Certain ITINs with middle digits (e.g., 70, 71, 72, 80) require renewal.

  • Renewal must be completed before filing to avoid refund delays.

Common Mistakes

  • Submitting photocopies instead of certified documents.

  • Missing signatures on Form W‑7.

  • Incorrect or expired documentation.

  • Using unverified agents instead of IRS‑approved Certified Acceptance Agents (CAAs).
