what is tin number in canada

In Canada, the Tax Identification Number (TIN) exists in various forms and is issued to residents and non-residents. The descriptions below focus on residents of Canada, for whom a TIN is required to be collected for exchange of information purposes under the Common Reporting Standard. For individuals resident in Canada, their authorized tax identification number is their nine-digit Canadian Social Insurance Number (SIN) issued by Service Canada. Corporations resident in Canada have a unique nine-digit Business Number (BN) issued by the Canada Revenue Agency. For trusts, their tax identification number is their eight-digit trust account number preceded by the letter "T" issued by the Canada Revenue Agency. Additionally, non-resident individuals who need an identification number can apply for an Individual Tax Number (ITN), which is a 9-digit number issued to non-resident individuals who are not eligible for a SIN and are considered non-residents for tax purposes. The ITN is used for various purposes such as filing an application to waive or reduce Canadian withholding tax, disposing of taxable Canadian property, filing a Canadian income tax return, and more. The ITN is also required for international students without a work permit to file a Canadian income tax return or to apply for family benefits and credits. The processing time for an ITN application is generally 4-6 weeks, and the application form is "Application for a Canada Revenue Agency Individual Tax Number (ITN) for Non-Residents” .
