General context

This is one of the most common processes for ITIN immigrants in the US. This guide covers step-by-step, frequent errors, and reliable resources.

Basic requirements

  • Current ITIN (not expired from 3 consecutive years of non-use)
  • Documented identity (current passport preferable)
  • Clear tax status (consistent returns from last 2-3 years)
  • Reliable email/phone for IRS communications

General steps

1. Verify eligibility

  • ITIN holders can do most tax and financial processes
  • Some services (W-2 employment with FICA match, federal EITC) require SSN

2. Gather documentation

  • Passport (preferable — verifies identity + status)
  • Recent tax returns (2-3 years)
  • Proof of US address
  • Account numbers (if applicable)

3. Apply / complete process

  • Appropriate form (W-7, SS-4, 1040, 1099, etc.)
  • Supporting documents
  • Payment (if applicable)
  • Submission confirmation

4. Wait for processing

  • IRS: variable by type (7-11 weeks for ITIN, 1-3 weeks for return)
  • Brokerage/banking: 5-15 business days
  • Mortgage: 30-60 days

5. Follow-up

  • Reference number / receipt
  • Periodically check status
  • Respond to IRS letters QUICKLY

Common errors

  1. Expired documents: passport expires during process = rejection
  2. Outdated addresses: causes lost IRS correspondence
  3. Multiple ITINs: each person only has ONE ITIN
  4. Mixing ITIN and SSN: if you get SSN later, do NOT use both in same year
  5. “Notario” fraud: paying for services available FREE

Reliable resources

  • Official IRS: irs.gov — always the primary source
  • CAA (Certifying Acceptance Agent): VITA sites have many, list at irs.gov/individuals/itin-acceptance-agent-program
  • VITA (Volunteer Income Tax Assistance): FREE for low income
  • CPA / Enrolled Agent with ITIN experience: for complex cases
