You have to register for GST/HST if:
You do not have to register if:
You are a small supplier and do not have to register if you meet one of the following conditions:
Total revenues from taxable supplies means your worldwide revenues from your supplies of goods and services that are subject to the GST/HST (including zero rated supplies), or that would be subject to the tax if supplied in Canada. It does not include goodwill, financial services, and sales of capital property. You also have to include the total revenues from taxable supplies of all of your associates in this calculation.
Note
If your total revenues from taxable supplies are over $30,000 ($50,000 for public service bodies) in a single calendar quarter or over four consecutive calendar quarters, you are no longer a small supplier and you have to register for the GST/HST.
Exception
Taxi and limousine operators, for their taxi operations, and non-resident performers selling admissions to seminars and other events must register for the GST/HST, even if they are small suppliers.
The effective date of your GST/HST registration depends on when you go over the small supplier threshold amount of $30,000 ($50,000 if you are a public service body). If your revenues are over the threshold amount in one calendar quarter, you are considered a registrant and must collect the GST/HST on the supply that made you go over the threshold amount. Your effective date of registration is the day of the supply that made you go over the threshold amount. You have 29 days from this day to apply for registration.
If you are under the threshold amount in one calendar quarter, but you are over the threshold during four consecutive calendar quarters, you are considered to be a small supplier for those four calendar quarters and a month following those quarters. Your effective date of registration would be the day the first supply was made after you cease being a small supplier. You have 29 days from this day to register for the GST/HST.
If you are a small supplier and you are engaged in a commercial activity in Canada, you can choose to register voluntarily, even though you do not have to. If you register voluntarily, you have to charge and remit the GST/HST on your taxable supplies of goods and services, and you can claim input tax credits (ITCs) for the GST/HST paid or payable on purchases related to these supplies. You have to stay registered for at least one year before you can ask to cancel your registration. For more information, see Guide RC4022, General Information for GST/HST Registrants.
If you choose not to register, you cannot charge the GST/HST, and you cannot claim ITCs.
Before you can register for a GST/HST account, you need a Business Number (BN). Your BN will be your business identification for all your dealings with us. For more information, see Booklet RC2, The Business Number and Your Canada Revenue Agency Program Accounts.
If you are incorporated, you may already have a BN and a corporate income tax account.
To set up a BN, a GST/HST account, and any other account you may need (for example, a payroll deduction or import account), go to Business Registration On-line, call 1-800-959-5525 , or send us a completed Form RC1, Request for a Business Number (BN).
Note
It is the person or business entity that registers for the GST/HST. For example, it is the partnership that registers and not each partner.
