CRA ITN (Form T1261) Guide
Interactive document checklist and application assistant for Canadian Individual Tax Numbers (ITNs).
Important CRA Rule: The Individual Tax Number (ITN) is only for non-residents and dependents who are **not eligible to get a Social Insurance Number (SIN)** but need a Canadian tax ID. Do NOT apply for an ITN if you or your dependents are eligible for a SIN (e.g. work permit holders, international students with off-campus work clearance).
