Registering your business
Not all businesses need a business number (BN) and program accounts. It is important to read Do you need a business number or a program account? before registering.
The BN is a nine-digit identifier for businesses to simplify their dealings with federal, provincial, and municipal governments in Canada. It aims to give each registered business its own unique number.
You only need a BN if you need one or more program accounts. A program account is an account you register for with the Canada Revenue Agency to deal with specific programs. The most common program accounts a business will need are GST/HST, payroll deductions, corporation income tax, and import-export.
If you already have a BN and you change the legal ownership or the structure of your business, you may have to register for a new BN. For more information, go to Changing your business status.
