About the Canada GST/HST/PST Calculator
This calculator adds Canadian sales tax to a price, or works backwards from a tax-included total to the pre-tax amount, for every province and territory. Pick the province where the sale takes place, enter the amount and choose whether it is before or after tax; it splits the tax into GST, HST and provincial sales tax so you can copy the figures straight onto an invoice or receipt.
Rates are the ones in force in 2026: 13% HST in Ontario, 14% HST in Nova Scotia (cut from 15% on 1 April 2025), 15% HST in New Brunswick, Newfoundland and Labrador and Prince Edward Island, 5% GST plus 7% PST in British Columbia and Manitoba (RST), 5% GST plus 6% PST in Saskatchewan, 5% GST plus 9.975% QST in Quebec, and 5% GST only in Alberta and the three territories.
Small businesses, freelancers and shoppers use it for quoting prices, checking receipts and splitting a total for bookkeeping. It applies the general rates; some goods and services are zero-rated or exempt (basic groceries, prescription drugs, many medical services) and provinces exempt or reduce PST on items such as children’s clothing, so check the rules for specific products.
With the default inputs, the total with tax is $113.00. Change any value above to recalculate instantly.

Formula and method
Every Canadian sales tax is charged on the pre-tax selling price. In the HST provinces (Ontario, Nova Scotia, New Brunswick, Newfoundland and Labrador and Prince Edward Island) a single harmonized tax replaces GST and provincial tax. In British Columbia, Manitoba and Saskatchewan the 5% GST and the provincial tax are both applied to the same base, and in Quebec the 9.975% QST has been calculated on the price excluding GST since 2013, so the rates simply add up.
To remove tax from a tax-included total, divide by one plus the combined rate. For example, $113 in Ontario ÷ 1.13 = $100 before tax, so the HST is $13. Results are not rounded to the cent until display; on a real invoice tax is normally rounded to the nearest cent on each line or on the total.

Worked examples
$100 purchase in Ontario
Ontario charges 13% HST, so $13 is added to a $100 price for a $113 total.
$250 before tax in Quebec
GST is 5% of $250 ($12.50) and QST is 9.975% of $250 ($24.94), for $37.44 of tax and a total of $287.44 — a combined 14.975%.
Removing tax from a $57.50 receipt in Nova Scotia
Dividing $57.50 by 1.14 gives a pre-tax price of $50.44, so $7.06 of the receipt is Nova Scotia’s 14% HST.
$1,200 laptop in British Columbia
BC charges 5% GST ($60) and 7% PST ($84) on the $1,200 price, so the laptop costs $1,344.
Frequently asked questions
What is the HST rate in Ontario?+
Ontario’s HST is 13%, made up of the 5% federal part and an 8% provincial part. It applies to most goods and services, with point-of-sale rebates of the provincial part on items such as children’s clothing, books and prepared food under $4.
What is the sales tax in Nova Scotia now?+
Nova Scotia’s HST fell from 15% to 14% on 1 April 2025. New Brunswick, Newfoundland and Labrador and Prince Edward Island still charge 15% HST.
Which provinces have no provincial sales tax?+
Alberta, Yukon, the Northwest Territories and Nunavut charge only the 5% GST. Alberta has no provincial sales tax, although it levies separate taxes on items such as fuel and hotel stays.
How do I calculate GST and QST in Quebec?+
Apply 5% GST and 9.975% QST separately to the pre-tax price and add both, for a combined 14.975%. Since 2013 QST is no longer charged on the GST, so there is no tax-on-tax.
How do I remove HST from a total?+
Divide the tax-included total by 1 plus the rate. For 13% HST, divide by 1.13; for 15%, divide by 1.15. The difference between the total and the result is the tax. Choose “Tax included” above to do this automatically.
Do I have to charge GST/HST as a small business?+
You must register and charge GST/HST once your worldwide taxable sales exceed $30,000 in a single calendar quarter or over four consecutive calendar quarters. Below that you are a small supplier and registration is optional.
