GST/HST & PST Calculator
Pick a province, enter an amount, and see the GST, HST, PST or QST — adding tax to a price, or backing it out of a total.
The same price in every province and territory

How Canadian sales tax is layered
Every province and territory sits under the federal Goods and Services Tax (GST) of 5%, but what happens on top of it depends on where the sale is made. There are three arrangements:
- HST provinces (Ontario, New Brunswick, Newfoundland and Labrador, Nova Scotia, Prince Edward Island) collect one combined Harmonized Sales Tax, administered by the CRA. It already contains the 5% federal part, so you never add GST on top.
- GST plus a separate provincial tax (British Columbia, Saskatchewan, Manitoba, Quebec). The provincial tax is its own line on the receipt and is run by the province. In Quebec it is called QST and is run by Revenu Québec.
- GST only (Alberta, the Northwest Territories, Nunavut and Yukon). Just the 5%.
The two taxes in the second group are not stacked on each other. The CRA says to calculate the GST on the price without the PST, and since 2013 Quebec has calculated the QST on the price before the GST. Both are taken from the same pre-tax amount, which is how this calculator works.
Sales tax rates by province and territory
Checked against the CRA and provincial sources in October 2026. The last column is the tax on a $100.00 purchase, each tax rounded to the nearest cent.
| Province or territory | GST | HST or provincial tax | Combined | Tax on $100 |
|---|---|---|---|---|
| Alberta | 5% | — | 5% | $5.00 |
| British Columbia | 5% | 7% PST | 12% | $12.00 |
| Manitoba | 5% | 7% RST | 12% | $12.00 |
| New Brunswick | — | 15% | 15% | $15.00 |
| Newfoundland and Labrador | — | 15% | 15% | $15.00 |
| Northwest Territories | 5% | — | 5% | $5.00 |
| Nova Scotia | — | 14% | 14% | $14.00 |
| Nunavut | 5% | — | 5% | $5.00 |
| Ontario | — | 13% | 13% | $13.00 |
| Prince Edward Island | — | 15% | 15% | $15.00 |
| Quebec | 5% | 9.975% QST | 14.975% | $14.98 |
| Saskatchewan | 5% | 6% PST | 11% | $11.00 |
| Yukon | 5% | — | 5% | $5.00 |
Nova Scotia cut its HST from 15% to 14% for supplies made on or after April 1, 2025. Rates do change, so confirm with the CRA or the province before you file or invoice.
Worked examples
Adding tax. A $100.00 item costs $113.00 in Ontario ($13.00 HST), $112.00 in British Columbia ($5.00 GST plus $7.00 PST), $114.98 in Quebec ($5.00 GST plus $9.98 QST) and $105.00 in Alberta. On a $1,000.00 job those become $1,130.00, $1,120.00, $1,149.75 and $1,050.00.
Why Quebec shows 9.98. 9.975% of $100.00 is $9.975, which rounds to $9.98. That is why Quebec's tax on $100 is $14.98 and not $14.97.
Taking tax out. A receipt for $113.00 in Ontario is $100.00 plus $13.00 HST. A receipt for $114.98 in Quebec is $100.00 plus $5.00 GST and $9.98 QST. You divide by one plus the combined rate (1.13 and 1.14975).
When a total cannot be matched exactly
Because each tax is rounded to the cent, not every total can come from a whole-cent price. In Quebec, for example, $1.03 cannot be produced exactly; the closest prices give $1.02. When that happens the calculator shows the closest price and says so, rather than pretending the maths is exact.
If you charge GST/HST as a business
You are a small supplier, and not required to register, while your worldwide taxable revenue is $30,000 or less in a single calendar quarter and over the last four consecutive calendar quarters. Pass that and you must register and start charging. Once registered you can claim input tax credits for the GST/HST you paid on business purchases, which is why the tax you collect is not your revenue.
Two terms trip people up. Zero-rated supplies, such as basic groceries, are taxable at 0%. Exempt supplies, such as most residential rent and many health services, are outside the tax altogether. Both show no tax on the receipt, but they are treated differently in your filing. This is a calculator, not tax advice; the CRA and your accountant decide what applies to you.
Putting the tax on an invoice? The invoice generator has a tax-rate field, and the sales tax calculator handles any other rate.
