GST/HST -> Registering to collect GST/HST

How do I register to collect GST/HST?

You can register online, by phone, or by mail.  If you don't already have a business number (BN), you will have to register for one.

To register online, see the Canada Revenue Agency (CRA) Business Registration Online page.  The online registration process asks for your personal information first, including your social insurance number, even though you may be registering a corporation.  You will be asked if the business already has a business number.  If it does not, you will go through the process of registering for a business number first.

You can register by phone for a business number or for CRA accounts (GST, income tax, payroll, etc.) by calling CRA at 1-800-959-5525.

To register by phone or by mail, see the CRA How to Register - Business Number page.

The CRA guide RC4022, General Information for GST/HST Registrants is a helpful resource for GST registrants.
