Canada Business Number Registration
A business number (BN) allows the Canada Revenue Agency (CRA) to identify a specific business (or other organization such as a charity) for tax matters related to business in Canada. Having a BN lets businesses and other organizations simplify their dealings with each other, as well as with all levels of the public sector. The BN is based on the idea that each organization has one unique nine-digit number.
Each sole proprietor, partnership, corporation, trust, or other ownership type, will be assigned one BN when they register for a program account. One business, one number throughout Canada.
The four major program accounts registered by the CRA are:
- goods and services tax/harmonized sales tax (GST/HST) (RT);
- payroll deduction (RP);
- import-export (RM); or
- corporation income tax (RC).
