Quebec charges GST 5% + QST 9.975% separately, and both are calculated on the pre-tax price.

Frequently asked questions
What are the GST, HST, PST and QST rates in each province?
GST is a flat 5% federal tax. Five provinces combine it with a provincial tax into one HST: Ontario 13%, Nova Scotia 14%, and New Brunswick, Prince Edward Island and Newfoundland & Labrador 15%. British Columbia (PST 7%), Manitoba (RST 7%) and Saskatchewan (PST 6%) charge a separate provincial tax on top of GST, Quebec charges QST of 9.975% plus GST, and Alberta and the three territories charge GST only.
Does Quebec charge QST on top of the GST?
No. Since January 1, 2013 QST has been calculated on the pre-tax price, the same base as GST, so the two are simply added together. On a $100 item that is $5.00 GST plus $9.98 QST (9.975%), for a total of $114.98 — a combined rate of 14.975%. Older guides that describe “tax on tax” in Quebec are out of date.
What changed with Nova Scotia’s HST?
Nova Scotia lowered its HST from 15% to 14% on April 1, 2025, by cutting the provincial portion from 10% to 9%. New Brunswick, Prince Edward Island and Newfoundland & Labrador remain at 15%. This calculator uses the 14% rate for Nova Scotia.
What is the difference between zero-rated and exempt supplies?
Zero-rated supplies are taxable at 0%, so the seller still registers and can claim input tax credits on its costs. Examples are basic groceries, prescription drugs and exports. Exempt supplies are outside the system: the seller charges no tax but cannot claim credits. Examples are residential rent, most health and dental services, child care and financial services.
Which GST/HST rate applies to an online purchase?
For goods shipped to you, the rate is generally that of the province where the goods are delivered, not where the seller is located. A buyer in Halifax pays 14% HST on an item shipped from Alberta, and a buyer in Calgary pays only 5% GST on an item shipped from Ontario.
How do I take the tax out of a receipt that already includes it?
Divide the total by one plus the combined rate. For a $113.00 total in Ontario, $113.00 ÷ 1.13 = $100.00, so the tax was $13.00. Choose “Extract tax” in the calculator to do this for any province. In British Columbia, Manitoba, Saskatchewan and Quebec use the combined rate (12%, 12%, 11% and 14.975%) because both taxes are charged on the pre-tax price.
When does a business have to register for GST/HST?
A business must register once its taxable revenue exceeds $30,000 across four consecutive calendar quarters (or in a single quarter). Below that threshold it is a small supplier and registration is optional. Registered businesses charge GST/HST on taxable sales and can claim input tax credits for the GST/HST they paid on business purchases.
Is GST/HST charged on restaurant meals and groceries?
Restaurant meals, snacks, candy and most prepared food are taxable. Basic groceries such as milk, bread, fruit, vegetables and meat are zero-rated, so you pay no GST/HST on them. Items sold in quantities that look like a single serving, such as one muffin, are usually taxable.

Sales tax rates by province and territory
Canada has three layers of sales tax: the 5% federal GST, provincial sales taxes (PST, RST or QST), and the HST that merges the two in the Atlantic provinces and Ontario. The combined rate you pay depends on the province where you buy or where the goods are delivered.
| Province / territory | Taxes charged | Combined rate |
|---|---|---|
| Alberta | GST 5% | 5% |
| British Columbia | GST 5% + PST 7% | 12% |
| Manitoba | GST 5% + RST 7% | 12% |
| New Brunswick | HST 15% | 15% |
| Newfoundland & Labrador | HST 15% | 15% |
| Northwest Territories | GST 5% | 5% |
| Nova Scotia | HST 14% | 14% |
| Nunavut | GST 5% | 5% |
| Ontario | HST 13% | 13% |
| Prince Edward Island | HST 15% | 15% |
| Quebec | GST 5% + QST 9.975% | 14.975% |
| Saskatchewan | GST 5% + PST 6% | 11% |
| Yukon | GST 5% | 5% |
Worked example: a $250 purchase in five provinces
The same $250 pre-tax price produces a different total depending on where you buy. Alberta is the cheapest at $12.50 of tax and Quebec the most expensive of these five at $37.44. In Quebec the QST works out to $24.94 and the GST to $12.50, both calculated on the $250 pre-tax price.
| Province | Tax charged | Total tax | Total price |
|---|---|---|---|
| Alberta | GST 5% | $12.50 | $262.50 |
| British Columbia | GST 5% + PST 7% | $30.00 | $280.00 |
| Ontario | HST 13% | $32.50 | $282.50 |
| Nova Scotia | HST 14% | $35.00 | $285.00 |
| Quebec | GST 5% + QST 9.975% | $37.44 | $287.44 |
How to add tax to a price or remove it from a total
To add tax, multiply the pre-tax price by one plus the combined rate: $250 × 1.13 = $282.50 in Ontario. To remove tax from a total that already includes it, divide by the same factor: $113.00 ÷ 1.13 = $100.00 and the tax was $13.00. Do not subtract the rate from the total, because 13% of $113 is $14.69, not $13.00. Where GST and a provincial tax are charged separately they both apply to the pre-tax price, so you can add the two rates together first.
Taxable, zero-rated and exempt purchases
Most goods and services are taxable at the full rate, including restaurant meals, clothing, electronics, haircuts and professional services. Basic groceries, prescription drugs, many medical devices, feminine hygiene products and exports are zero-rated. Residential rent, most health and dental care, child care, music lessons and financial services are exempt. The calculator applies the standard rate, so use it for taxable purchases; zero-rated and exempt items carry no tax.
For businesses: collecting tax and claiming input tax credits
Once taxable sales pass $30,000 over four consecutive calendar quarters you must register, charge GST/HST (and PST where it applies) and file regular returns. Each return nets the tax you collected against the GST/HST you paid on business expenses, which you recover as input tax credits. Keep the invoice for every expense you claim, since the supplier’s registration number and the tax shown are required support. Provincial taxes such as BC PST and Saskatchewan PST are administered separately from GST/HST and generally do not qualify for credits.
