How it works. Five provinces charge a single HST. Alberta and the territories charge 5% GST only. BC, Saskatchewan, Manitoba and Quebec charge GST plus their own provincial sales tax, and both parts are itemized below. Reverse mode divides the total by one-plus-the-rate to recover the pre-tax price.

How sales tax works across Canada

Every sale in Canada starts with the 5% federal GST. Five provinces — Ontario, Nova Scotia, New Brunswick, Newfoundland and Labrador, and PEI — blend it with their provincial portion into a single HST charged at 13% to 15%. British Columbia, Saskatchewan and Manitoba charge a separate provincial sales tax on top of GST, and Quebec charges QST at 9.975%. Alberta and the three territories charge nothing beyond the 5% GST.

Which rate applies is a place-of-supply question: broadly, you charge the rate of the province where the customer takes delivery, not where your business sits. That is why an Ontario seller shipping to Halifax charges Nova Scotia's rate.

What this calculator does not cover

Zero-rated supplies (basic groceries, exports, prescription drugs) carry 0% tax, and exempt supplies (most health care, residential rent, many financial services) carry none at all — this tool assumes a fully taxable sale. It also does not decide place-of-supply for you. If you are unsure what to charge, or whether you should be registered at all, see GST/HST and sales tax services or try the registration threshold checker.

Frequently asked questions

Multiply the pre-tax price by the combined rate for the buyer’s province: 13% in Ontario means $100 becomes $113. This calculator itemizes the federal and provincial parts for the GST-plus-PST provinces.
Divide the tax-included total by one plus the rate. In Ontario, $113 divided by 1.13 gives the $100 pre-tax price; the difference is the $13 tax. Switch this calculator to reverse mode to do it for any province.
It is 14% as of April 1, 2025, down from 15%. The other HST provinces stayed put: Ontario at 13%, and New Brunswick, Newfoundland and Labrador and PEI at 15%.
Generally the province where the goods are delivered or the service’s customer is located — the place-of-supply rules — not where your business is based. Selling from Toronto to a Calgary customer normally means charging 5% GST, not 13% HST.
