Overview of the Canadian Tax System
Canada employs a multi-tiered tax system consisting of both federal and provincial taxes. The federal Goods and Services Tax (GST) applies nationwide, while provinces may implement their own sales taxes, either separately or in combination with the GST, forming the Harmonized Sales Tax (HST).
Provinces with HST:
- New Brunswick
- Newfoundland and Labrador
- Nova Scotia
- Ontario
- Prince Edward Island
Provinces with Separate Sales Taxes:
- British Columbia (BC) – Provincial Sales Tax (PST)
- Manitoba (MB) – Retail Sales Tax (RST)
- Quebec (QC) – Quebec Sales Tax (QST)
- Saskatchewan (SK) – Provincial Sales Tax (PST)
Provinces with No Provincial Sales Tax:
- Alberta
- Northwest Territories
- Nunavut
- Yukon
Registering for Tax Collection
Federal and provincial tax registration requirements vary depending on whether a business is located within Canada or operating from outside the country.
Federal GST/HST Registration
Businesses, whether domestic or foreign, must register for GST/HST collection if they exceed certain revenue thresholds.
Threshold for Federal Tax Registration:
- $30,000 CAD in taxable sales within a 12-month period
- Applies to both digital and physical goods sold to Canadian consumers
Businesses based outside of Canada must register under either a normal GST/HST regime or a simplified GST/HST regime, depending on the nature of their sales activities.
Provincial Sales Tax Registration
Each province with a separate sales tax has its own registration requirements:
British Columbia (BC) – PST
- Threshold: $10,000 CAD in taxable sales over a 12-month period
- Applicable Transactions: All taxable goods and services sold to BC customers
Manitoba (MB) – RST
- Threshold: No monetary threshold; registration required for any taxable sales
- Applicable Transactions: All taxable goods and services sold in Manitoba
Quebec (QC) – QST
- Threshold: $30,000 CAD in taxable sales over a 12-month period
- Applicable Transactions: Digital and physical goods sold to Quebec residents
- Different registration types apply depending on whether the business is local or remote
Saskatchewan (SK) – PST
- Threshold: No monetary threshold; registration required for any taxable sales
- Applicable Transactions: All taxable goods and services sold in Saskatchewan
Tax Calculation and Compliance
Tax obligations are determined based on the location of the customer:
- Sales to Canadian customers incur GST, HST, or provincial sales taxes based on their location.
- Sales to customers outside Canada are generally zero-rated (not subject to Canadian sales tax), though taxes in the destination country may apply.
- Digital services and products provided by foreign sellers to Canadian consumers may require tax collection under special provincial or federal rules.
Exemptions and Special Cases:
- Businesses selling exclusively through online marketplaces that handle tax collection are generally not required to register for tax collection.
- For business-to-business (B2B) transactions, customers providing valid GST/HST or QST registration numbers may be exempt from tax collection in some cases.
