Calculate Canadian prices including or excluding GST 5% and HST 13%, 14%, or 15%.
Federal GST is 5%. HST is 13% in Ontario, 14% in Nova Scotia effective April 1, 2025, and 15% in New Brunswick, Newfoundland and Labrador, and Prince Edward Island. BC, Manitoba, Saskatchewan, and Quebec add a separate provincial tax, so confirm the place-of-supply rate before filing.
Adding tax to a pre-tax price: multiply the pre-tax price by (1 + tax rate). Example: a CA$100 pre-tax price at 13% HST becomes CA$100 × 1.13 = CA$113 after-tax. The tax amount is CA$13. Removing tax from an after-tax price: divide the after-tax price by (1 + tax rate). Example: a CA$113 after-tax price at 13% HST yields CA$113 ÷ 1.13 = CA$100 pre-tax. Tax amount directly: Tax = After-tax price × (rate ÷ (1 + rate)). For CA$113 at 13%: Tax = CA$113 × (0.13 ÷ 1.13) = CA$13.
Businesses with total taxable revenues (worldwide) exceeding CA$30,000 over four consecutive calendar quarters (or in a single quarter) must register for a GST/HST account with the Canada Revenue Agency (CRA) and start charging tax. Businesses below this "small supplier" threshold may register voluntarily to claim Input Tax Credits (ITCs) on their own purchases. Once registered, businesses charge GST or HST based on the place-of-supply rules (generally the customer's province for goods delivered within Canada), collect the tax, and remit it to the CRA — Quebec administers its own GST/QST jointly through Revenu Québec.
Registered businesses file GST/HST returns monthly, quarterly, or annually depending on their revenue (annual filers with revenue below CA$1.5M, quarterly up to CA$6M, monthly above that, though smaller businesses can elect more frequent filing). The return nets output tax collected against Input Tax Credits (GST/HST paid on business expenses); a positive balance is remitted to the CRA, and a negative balance triggers a refund. Late filing and remittance incur interest and penalties.
For goods and services sold to customers in other provinces, GST/HST generally applies based on the destination (the customer's province), not the seller's location — a business in Alberta (GST-only) shipping to Ontario generally must charge Ontario's 13% HST on that sale. Digital and cross-border e-commerce sellers meeting the revenue threshold must also register and collect the correct provincial rate for each customer's location, similar in spirit to the EU's destination-based digital VAT rules but administered separately by the CRA (and Revenu Québec for Quebec-bound sales).
For Ontario sales: select HST 13% and "Add Tax" to see the price to charge, including tax. For federal-only estimates (e.g., Alberta, which has no provincial sales tax): select GST 5%. For other provinces with HST at 15% (Atlantic Canada) or GST + separate PST/QST (BC, Manitoba, Saskatchewan, Quebec), add the provincial component manually until a province selector is available — this tool currently supports two representative rates (GST 5% federal, HST 13% Ontario) rather than every provincial combination.
