How to Get a Tax Identification Number (TIN) in Canada: Step-by-Step Guide (2026)
To get a Tax Identification Number (TIN) in Canada, you must apply for the correct type based on your situation: a Social Insurance Number (SIN) for individuals, a Business Number (BN) for businesses, or an Individual Tax Number (ITN) for non-residents. The process involves submitting identification documents, applying through the appropriate authority, and receiving your number.
Canada does not use a single universal TIN. Instead, different tax identification numbers are issued depending on whether you are an individual, business, or foreign taxpayer.
