Eligibility Requirements and Documentation for ITIN Applicants

Who Must Provide an ITIN

Individuals who need a federal tax processing number but are not eligible for a Social Security Number apply for an ITIN. This includes certain nonresidents, their dependents, and domestic partners who fall under specific filing requirements.

Acceptable Supporting Evidence

Submit original or certified copies of identity and foreign status documents. The IRS accepts passports, national ID cards, and visas, provided they are current and show your name and country of origin.

How to Submit Forms to the ITIN Address

Paper Return Submission Process

When mailing a completed Form W-7 or a tax return with an ITIN application, place all pages in a single envelope. Include the correct postage and avoid staples or binding to prevent processing delays at the ITIN Operation Unit.

Electronic Options and Attachments

E-file options allow you to attach scanned copies when authorized. If the IRS requests original documents, follow their instructions for secure mail and keep a copy of everything you send.

ITIN Status Tracking and Timing Expectations

Where to Check Processing Times

Use the Where’s My ITIN? tool and the ITIN status online portal to monitor your submission. These resources show current processing milestones and any additional information the IRS may request.

Typical Processing Windows

Standard timelines vary by workload, with initial applications often taking around 7 weeks. Expiring ITIN renewals and corrections may be completed in approximately 5 weeks when the submission is accurate and complete.

Common Mistakes and How to Avoid Them

Incomplete Signatures and Missing Dates

Unsigned forms or missing dates are among the most frequent reasons for delays. Ensure every required line is signed and dated, and verify that foreign status codes match the supporting documents.

Incorrect Address Format

Using a routing number or a general city address instead of the designated ITIN Operation Unit line can redirect your submission. Always confirm the exact ITIN address before placing items in the mailbox or scheduling a pickup.

Maintaining Compliance and Updating Your ITIN Information

Keeping your details accurate and current supports smoother refunds, approvals, and professional representation. Regular reviews of status and expiration dates reduce the risk of last-minute complications.

  • Check your ITIN expiration date at least once a year
  • Use the official ITIN status portal for real-time updates
  • Mail all correspondence to the ITIN Operation Unit with Mail Code 6090
  • Keep copies of every form and document you submit
  • Verify acceptance receipts and tracking numbers when mailing
