1. Overview of CRA Individual Tax Numbers (ITN - Form T1261)
An Individual Tax Number (ITN) is a unique 9-digit tax processing number issued by the Canada Revenue Agency (CRA) to non-resident individuals who are NOT eligible to receive a Social Insurance Number (SIN) but need a tax ID to file a Canadian tax return or be claimed as a dependent.
Key Policy Highlights & Benchmarks
- ITN Purpose: Issued to non-resident family members (e.g. non-resident spouse living abroad) so a Canadian taxpayer can claim spousal or dependent tax credits
- Ineligible for SIN Holders: If an individual is eligible for a Social Insurance Number (SIN), they CANNOT apply for an ITN
- Form T1261 Submission: Requires completing CRA Form T1261 and attaching certified true copies of primary identity documents (passport)
- Paper Tax Return Requirement: First-time ITN applications MUST be submitted by paper mail attached to a T1 tax return
Mandatory Action Checklist
✓Complete CRA Form T1261 (Application for a CRA Individual Tax Number for Non-Residents)
✓Obtain certified true copy of non-resident spouse/dependent passport from a notary public or lawyer
✓Attach Form T1261 and passport copy to your paper T1 income tax return and mail to CRA
