Canadian sales tax calculator (GST, HST, PST, QST)
Sales tax in Canada is 5% GST in every province and territory, plus a provincial tax in some: 13% HST in Ontario, 14% in Nova Scotia, 15% in the other Atlantic provinces, and 5% GST plus 9.975% QST in Quebec. Pick the province, enter a price before tax or a total, and the tool shows each tax line and the total.
Each tax is rounded to the cent on its own line, as on an invoice.

Rates checked November 5, 2026: CRA, GST/HST provincial rates table (canada.ca); Revenu Québec, Calculating the taxes (revenuquebec.ca); Province of British Columbia, PST (gov.bc.ca); Government of Saskatchewan, Provincial Sales Tax (saskatchewan.ca); Manitoba Finance, Retail Sales Tax (gov.mb.ca).
Why check each tax line
An invoice in Quebec shows the GST and the QST on separate lines, and a receipt in British Columbia shows GST and PST apart. When you only have a total, you need the amount before tax and each tax to record the expense or claim input tax credits. Working it back by hand is where rounding mistakes creep in.
Know what each vehicle costs you
Taxes are one line on a fleet's bills; fuel and repairs are the big ones. High Point GPS fleet tracking records every trip, distance, idle time and fuel use from engine data, with engine hours and maintenance reminders, so you can see the cost of each vehicle. FleetZap keeps the maintenance work orders.

Use the rate of the province where the sale is made, which for goods is usually where they are delivered.
In Quebec, the QST is charged on the price before GST, not on the price plus GST.
Round each tax to the cent on its own line, the way it appears on an invoice.
Some goods and services are zero-rated or exempt, so check before you charge tax on them.
Sales tax questions
- What is the sales tax rate in each province?
- The GST is 5% everywhere in Canada. Ontario charges 13% HST, Nova Scotia 14%, and New Brunswick, Newfoundland and Labrador and Prince Edward Island 15%. Quebec adds 9.975% QST, British Columbia and Manitoba add 7%, and Saskatchewan 6%. Alberta and the three territories charge GST only. These are the general rates published by the CRA and the provinces.
- How do I calculate GST and QST in Quebec?
- Multiply the price before tax by 5% for the GST and by 9.975% for the QST, round each to the cent, then add both to the price. On $100, the GST is $5.00 and the QST is $9.98, for a total of $114.98. Revenu Québec says the QST is calculated on the selling price excluding the GST.
- How do I find the price before tax from a total?
- Choose the mode that works back from a total and enter the amount paid. Each tax is the total times its rate divided by 100 plus all the rates, so in Quebec the QST is the total times 9.975 divided by 114.975. The amount before tax is what is left. On a $100 Quebec total, that gives $86.97 before tax.
- Is everything taxed at these rates?
- No. The rate depends on what is sold and where it is supplied. Some goods and services, such as basic groceries, are zero-rated, others are exempt, and provinces set their own exemptions and special rates. This calculator applies the general rates only and is not tax advice, so check the CRA or your province, or ask an accountant.
- Is the QST or PST charged on top of the GST?
- No. In Quebec, British Columbia, Manitoba and Saskatchewan, the provincial tax is calculated on the price before GST, so both taxes use the same base. That is why the QST on $100 is $9.98, not 9.975% of $105. In the HST provinces, one combined tax replaces both.
