Sales Tax Calculator (Canada)

How to use the sales tax calculator

1. Choose Add tax (price before tax → total) to go from a price to the amount you pay, or Remove tax (total → price before tax) to find the price and taxes hidden in a receipt total.
2. Type the Price before tax (or the Total including tax in reverse mode), for example 100 or 49.99.
3. Pick the Province or territory where the sale is taxed.

The tool shows the Price before tax, the Total tax, the Total and the Combined rate, plus a Tax breakdown with one line per tax: GST, HST, PST, RST or QST. Copy copies the breakdown as text, How it was calculated shows the arithmetic, and Sales tax rates by province and territory lists every jurisdiction with the date the rates were last checked.

Current rates by province and territory

• HST (harmonized, one line): Ontario 13%; Nova Scotia 14% (down from 15% since April 1, 2025); New Brunswick, Newfoundland and Labrador and Prince Edward Island 15%.
• GST 5% + provincial tax: British Columbia PST 7% (12% combined), Manitoba RST 7% (12%), Saskatchewan PST 6% (11%), Quebec QST 9.975% (14.975%).
• GST 5% only: Alberta, Yukon, Northwest Territories and Nunavut.

Rates were checked against the Canada Revenue Agency GST/HST rate page, Revenu Québec and the finance ministries of British Columbia, Manitoba and Saskatchewan. They are the general rates; some goods and services are zero-rated (basic groceries, prescription drugs) or exempt, and some provinces apply special rates to items such as alcohol, vehicles or insurance. The rate list is reviewed every year.

How each tax is calculated

Each tax is calculated separately on the price before tax and rounded to the cent:

GST = price × 5%; PST or QST = price × provincial rate; total = price + all taxes

There is no tax on tax. In particular, since January 1, 2013, the Quebec QST is calculated on the selling price excluding the GST. On a $100 purchase in Quebec: GST = $5.00, QST = $100 × 9.975% = $9.975, rounded to $9.98, total $114.98. In Ontario, the single HST line is $13.00 and the total $113.00.

Removing tax from a total (reverse calculation)

To find the price before tax, divide the total by (1 + combined rate):

price = total / (1 + rate)

For $113.00 in Ontario: 113 / 1.13 = $100.00. Because each tax is rounded separately, a few totals cannot be produced by any price in whole cents (for example with the two Quebec taxes). In that case the tool keeps the closest price and tells you that it gives a total one cent away. It never shows a price that does not match its own tax lines.
