A Canada sales tax calculator adds or removes the sales tax that applies in your province or territory: 5% GST everywhere, plus HST, PST, QST or RST where they apply. Pick a province, type the price, and the calculator shows the tax breakdown and the total with the working.
Quick answer: To add Canadian sales tax, multiply the price by the combined rate: $100 in Ontario × 13% HST = $13, so the total is $113. To remove it, divide the total by 1 plus the rate: $113 ÷ 1.13 = $100. The combined rate is 5% in Alberta and the territories, 13% in Ontario, 14% in Nova Scotia, 15% in the other HST provinces, 11% to 12% where PST applies and 14.975% in Quebec.
How to use the Canada sales tax calculator
The Canada sales tax calculator updates as you type, so it has no Calculate button. It works for any price in Canadian dollars or another currency.
- Choose Add tax if you know the price before tax, or Remove tax if you know the price with tax included.
- Type the amount. Use the currency menu if you want a different symbol, such as C$.
- Pick the province or territory. The GST, HST, PST, QST or RST rates are filled in for you.
- Optional: type a combined rate in the override box if a rate changes or you want to test a different one.
- Read the total, the breakdown into GST and provincial tax, the table of every province, and the working.
| Box | What to type | What you get |
|---|---|---|
| Amount | The price before tax, or the total with tax. | The other figure, the tax, and the breakdown. |
| Province or territory | One of the 13 provinces and territories. | The GST/HST/PST/QST rates for that place. |
| Total tax rate | Optional. Any combined rate from 0 to 100. | Overrides the province for the whole calculation. |
Sales tax by province: GST, HST, PST and QST rates
Canada has a federal GST of 5% that applies in every province and territory. Five provinces combine it with their own tax into one harmonized sales tax, the HST. Four provinces charge a separate provincial tax, called PST in British Columbia and Saskatchewan, RST in Manitoba and QST in Quebec.
Alberta, the Northwest Territories, Nunavut and Yukon have no provincial or territorial sales tax. The Canada sales tax calculator uses the same figures as this table, which comes from the Canada Revenue Agency’s GST/HST rates, checked in October 2026, with the provincial sites for PST, RST and QST.
| Province or territory | Taxes charged | Combined rate | Tax on $100 | Total on $100 |
|---|---|---|---|---|
| Alberta | GST 5% | 5% | $5.00 | $105.00 |
| British Columbia | GST 5% + PST 7% | 12% | $12.00 | $112.00 |
| Manitoba | GST 5% + RST 7% | 12% | $12.00 | $112.00 |
| New Brunswick | HST 15% | 15% | $15.00 | $115.00 |
| Newfoundland and Labrador | HST 15% | 15% | $15.00 | $115.00 |
| Northwest Territories | GST 5% | 5% | $5.00 | $105.00 |
| Nova Scotia | HST 14% | 14% | $14.00 | $114.00 |
| Nunavut | GST 5% | 5% | $5.00 | $105.00 |
| Ontario | HST 13% | 13% | $13.00 | $113.00 |
| Prince Edward Island | HST 15% | 15% | $15.00 | $115.00 |
| Quebec | GST 5% + QST 9.975% | 14.975% | $14.98 | $114.98 |
| Saskatchewan | GST 5% + PST 6% | 11% | $11.00 | $111.00 |
| Yukon | GST 5% | 5% | $5.00 | $105.00 |
Why use a Canada sales tax calculator?
Canadian prices on shelves and websites usually appear before tax, and the tax you pay depends on where the sale is made. A Canada sales tax calculator removes the guesswork: it applies the right federal and provincial taxes for the place of sale and shows how much of the total is tax. Shoppers use a Canada sales tax calculator to budget, and small businesses use it to quote customers in other provinces, where the rate can differ by as much as 10 percentage points.
HST calculator Ontario: 13% HST
This HST calculator Ontario setting uses the combined rate of 13%, which is the 5% federal part plus an 8% provincial part. There is no separate PST in Ontario, so the price tag and the receipt show one 13% HST line. The same single-line approach applies in New Brunswick, Newfoundland and Labrador and Prince Edward Island at 15%, and in Nova Scotia at 14%.
Worked example: add 13% HST to $250.00
HST = $250.00 × 13 ÷ 100 = $32.50, so the total is $250.00 + $32.50 = $282.50. Multiplying $250.00 by 1.13 gives the same answer. Choose Ontario and type 250 in the calculator to see it.

| Price before tax | HST at 13% | Total with HST |
|---|---|---|
| $10.00 | $1.30 | $11.30 |
| $25.00 | $3.25 | $28.25 |
| $50.00 | $6.50 | $56.50 |
| $100.00 | $13.00 | $113.00 |
| $250.00 | $32.50 | $282.50 |

GST HST calculator: how to calculate HST
Learning how to calculate HST takes two lines, and the same two lines work for GST. Write the combined rate as a decimal by dividing it by 100.
- Tax = price before tax × rate ÷ 100
- Total = price before tax + tax, or price × (1 + rate ÷ 100)
This GST HST calculator, like the Canada sales tax calculator above, applies the formula to the combined rate for the province. For a province with a separate PST or QST, the tax is the GST plus the provincial tax, each worked out on the price before tax. In British Columbia that is 5% + 7% = 12%, in Saskatchewan 5% + 6% = 11% and in Manitoba 5% + 7% = 12%.
Reverse HST calculator: how to remove tax from a total
A reverse HST calculator starts from the total on the receipt and works back to the price before tax. Do not take 13% off the total, because the tax was added to the smaller price. Divide instead.
- Price before tax = total ÷ (1 + rate ÷ 100)
- Tax = total − price before tax
Worked example: remove 13% HST from $113.00
Price before tax = $113.00 ÷ 1.13 = $100.00. Tax = $113.00 − $100.00 = $13.00. In Ontario the HST is 13 ÷ 113 of the total, which is 11.5%, so a $113.00 receipt always contains $13.00 of tax. Taking 13% off $113.00 would leave $98.31, which is wrong by $1.69.
Reverse tax share by rate
| Where | Combined rate | Tax as % of the total | Divide the total by | Tax in a $1,000 total |
|---|---|---|---|---|
| Alberta, territories | 5% | 4.76% | 1.05000 | $47.62 |
| Saskatchewan | 11% | 9.91% | 1.11000 | $99.10 |
| British Columbia, Manitoba | 12% | 10.71% | 1.12000 | $107.14 |
| Ontario | 13% | 11.50% | 1.13000 | $115.04 |
| Nova Scotia | 14% | 12.28% | 1.14000 | $122.81 |
| Quebec | 14.975% | 13.02% | 1.14975 | $130.25 |
| New Brunswick, Newfoundland and Labrador, PEI | 15% | 13.04% | 1.15000 | $130.43 |
Nova Scotia HST change: 14% from April 1, 2025
The Canada Revenue Agency states that as of April 1, 2025, the HST rate decreased to 14% in Nova Scotia, down from 15%. The provincial part fell from 10% to 9%, while the federal part stayed at 5%. On a $100.00 purchase the tax is now $14.00 and the total is $114.00, compared with $15.00 and $115.00 at the old 15% rate. Some older pages and receipts still show 15%, so use 14% for current purchases and type 15 in the override box if you need to check an older sale.
PST and RST: British Columbia, Saskatchewan and Manitoba
These three provinces charge a separate provincial sales tax on top of the 5% GST. The BC government says the rate of PST is generally 7% of the purchase or lease price of goods and services, with some exceptions. The Government of Saskatchewan calls PST a six per cent sales tax, and Manitoba says its general retail sales tax rate is 7%, calculated on the selling price before GST.
Because the provincial tax is worked out on the price before GST, the two taxes simply add up. A $100.00 item in British Columbia carries $5.00 of GST and $7.00 of PST, so the total is $112.00. Rules about which goods are taxed differ by province, so check the provincial tax office for items such as restaurant meals, software or children’s clothing.
Quebec sales tax calculator: GST and QST
This Quebec sales tax calculator setting charges 5% GST and 9.975% QST, a combined 14.975%. Revenu Québec works out the QST on the selling price excluding the GST, so the two taxes add up without compounding. On a $100 price the GST is $5.00, the QST is $9.975, which rounds to $9.98, and the total is $114.98.
On $250.00 the tax is $37.44, made of $12.50 of GST and $24.94 of QST, and the total is $287.44. To go the other way, divide the total by 1.14975.
Alberta and the territories: only 5% GST
Alberta, the Northwest Territories, Nunavut and Yukon have no provincial or territorial sales tax, so the combined rate is the 5% GST. A $100 purchase costs $105.00, and a $210 receipt contains $10.00 of GST.
Which items does the Canada sales tax calculator tax? Zero-rated and exempt goods
The Canada sales tax calculator applies the full rate to the amount you type. In practice some goods and services are zero-rated or exempt from GST/HST, and basic groceries are a common example, while provincial taxes have their own lists of exemptions. Taxable items on one receipt can be mixed with untaxed ones, so type only the taxable part of the bill. Check the Canada Revenue Agency or your provincial tax office for a specific product.
Canada sales tax calculator questions and answers
Try these on paper first, then check each one with the Canada sales tax calculator.
- Add Ontario HST to a $60 price. HST = $60 × 0.13 = $7.80, so the total is $67.80.
- A New Brunswick receipt shows $115.00 with 15% HST. What was the price before tax? $115 ÷ 1.15 = $100.00, and the HST is $15.00.
- A $80 jacket in British Columbia has 5% GST and 7% PST. What is the total? Tax = $80 × 0.12 = $9.60, so the total is $89.60.
- A Nova Scotia bill is $228.60 with 14% HST. What is the HST? $228.60 ÷ 1.14 = $200.53 before tax, so the HST is $28.07.
- A $40 item in Quebec carries 5% GST and 9.975% QST. What is the total? Tax = $40 × 0.14975 = $5.99, so the total is $45.99.
Canada sales tax calculator: common mistakes
- Taking the rate off the total. 13% off $113 leaves $98.31, but the price before tax is $100. Always divide by 1.13.
- Using the wrong province. The place of supply sets the rate. Compare Ontario at 13% with Alberta at 5% before you shop or quote.
- Compounding GST and PST. In BC, Saskatchewan, Manitoba and Quebec both taxes are worked out on the price before GST, so add the two rates.
- Using the old Nova Scotia rate. HST there has been 14% since April 1, 2025.
- Taxing untaxed items. Zero-rated and exempt goods should be left out of the amount.
When to use a Canada sales tax calculator: real-life examples
- Freelancers and small businesses. A $2,400.00 Ontario invoice before tax becomes $2,712.00 with HST, of which $312.00 is collected for the government.
- Checking a receipt. A $226.00 Ontario total includes $26.00 of HST on a $200.00 price.
- Selling across provinces. A $1,200.00 sale to a Quebec customer carries $179.70 of tax, so the customer pays $1,379.70.
- Comparing prices. A $500 item costs $525.00 in Alberta, $565.00 in Ontario and $574.88 in Quebec, so the same sticker price lands very differently.
