If you are operating a business in Canada, you need to know about the Goods and Services Tax (GST) and the Harmonized Sales Tax (HST) and you MUST charge GST/HST unless your business qualifies as an exception. We summarized general basic rules of GST/HST that each business owners should know. However, type of business and location that you are operating may have different rules and exemptions.

1. GOOD and SERVICES TAX (GST)/ HARMONIZED SALES TAX (HST): GST is a tax that applies to most supplies of good and services which made in Canada. And HST is a combination of federal GST and Provincial Sales Tax (PST) into a single value added sales tax. However, only five Canadian provinces charge HST (Ontario, New Brunswick, Nova Scotia, Newfoundland & Labrador and Prince Edward Island) and each provinces HST rate can vary, all provinces and their GST, PST and HST rates provided below.

2. REGISTRATION: You have to register for the GST/HST account if you provide taxable supplies in Canada and you are NOT a small supplier. If your taxable revenues more than $30,000 in a single calendar quarter or over four consecutive calendar quarters, you are NO longer a small supplier.

However, if you are a small supplier, you CAN still register GST/HST account voluntarily. Once you are registered, you HAVE to charge and remit the GST/HST and you have to stay registered for at least one year before you can request to cancel your registration.
