Eligibility Criteria
Not all businesses require a Business Number (BN). You only need a BN if you require any one of the following business accounts:
-
GST/HST
-
Payroll
-
Corporate income tax
-
Import/Export
Summary
The Business Number (BN) is a 9-digit identifier used in Canada to which businesses can register program accounts with the Canada Revenue Agency (CRA). This number should be used when communicating with the CRA about accounts you have or wish to create.
How do I get a Business Number?
Internet
Business Registration On-line is a service that allows you to register for a BN or a CRA account via the Internet. You can also register for some provincial programs accounts at the same time. Businesses that do not have complex registration requirements can use this service.
Telephone
You can register for a BN and CRA account(s) by calling the Business Enquiries line.
You can register for a Business Number (BN) and CRA accounts by completing Form RC1, Request for a Business Number (BN) and mailing or faxing it to your tax services office.
Quebec
If you operate your business in Quebec, you will have to register your GST/HST account(s) with the Ministère du revenu du Québec (MRQ). To register your payroll, import/export, or corporation income tax accounts you must still contact the CRA.
