What Makes A Valid Sample Letter to Cancel Itin

A good cancellation letter isn’t just a note saying you want to close the number. It includes every detail the IRS requires to locate your file immediately. Missing even one required detail will add 8-12 weeks to your processing time.

Every valid cancellation letter must include these items:

  • Your full legal name matching IRS ITIN records
  • The 9-digit ITIN number being cancelled
  • Your current verified mailing address
  • Clear, specific reason for cancellation
  • Original handwritten signature

Supporting Document Requirement Status
Government photo ID Mandatory
Original ITIN assignment letter Recommended
Proof of SSN (if applicable) Required for replacement cases

Always mail this letter via certified mail with return receipt. This gives you official proof the IRS received your request. Never email cancellation requests, as the IRS does not accept digital submissions for this process.
