🍁 What is the GST/QST Calculator for Canada?

Canadian sales taxes are a multi-layer system that combines a federal Goods and Services Tax (GST) of 5% with provincial taxes that vary by jurisdiction. In Quebec, the provincial tax is called the taxe de vente du Quebec (QST) at 9.975%, giving a combined rate of 14.975%. In Ontario and the Atlantic provinces, the federal and provincial components are merged into a Harmonized Sales Tax (HST) at 13% or 15%. British Columbia, Manitoba, and Saskatchewan collect the GST separately alongside their own provincial sales tax (PST or RST). Alberta, Northwest Territories, Nunavut, and Yukon apply only the 5% federal GST.

This calculator handles every province and territory in Canada for 2025. A Quebec resident buying a $500 appliance wants to know the full cost including both GST and QST before making a purchase decision. A small business owner in Ontario needs to collect the correct 13% HST on invoices and remit it to the Canada Revenue Agency (CRA). An accountant in British Columbia reconciling supplier invoices needs to extract the GST amount separately from the PST for input tax credit (ITC) claims. A traveler comparing prices across provinces can see that buying in Alberta (5% only) saves significantly compared to Quebec (14.975%) on large purchases.

A common misconception is that all of Canada uses a single sales tax system. In practice, there are three systems operating simultaneously: HST provinces where the CRA collects everything, GST+QST in Quebec where the CRA collects GST and Revenu Quebec collects QST, and GST+PST provinces where the CRA collects GST and the province collects PST through its own department. This calculator automatically handles all three systems and shows the federal and provincial components separately so you can track each for remittance and claiming purposes.

The Remove Tax mode is particularly useful for bookkeeping. When a receipt shows only a tax-inclusive total, you need the pre-tax base to record the correct GST or QST for an ITC or input tax refund (ITR) claim. Dividing manually by 1.14975 (Quebec) or 1.13 (Ontario) is error-prone. This calculator does it instantly for any province.

📐 Formula

Tax  =  Price × (Rate ÷ 100)
Tax = tax amount in Canadian dollars
Price = pre-tax price in Canadian dollars
Rate = combined tax rate for the province (%)
Quebec: GST = Price × 0.05 | QST = Price × 0.09975 | Total = Price × 0.14975
Ontario: HST = Price × 0.13 (federal 5% + provincial 8%)
Total Price = Price + Tax
Pre-Tax  =  Total ÷ (1 + Rate ÷ 100)
Pre-Tax = price before tax, extracted from a tax-inclusive total
Total = tax-inclusive price
Rate = combined provincial + federal tax rate (%)
Example (Quebec Add): C$200 x 0.14975 = C$29.95 tax, total C$229.95
Example (Quebec Remove): C$229.95 / 1.14975 = C$200.00 pre-tax

💡 Example Calculations

Example 1: Electronics Purchase in Quebec

C$200 pre-tax purchase in Quebec (GST 5% + QST 9.975% = 14.975%)

1
Pre-tax price = C$200.00
2
GST = C$200.00 x 0.05 = C$10.00
3
QST = C$200.00 x 0.09975 = C$19.95
4
Total Tax = C$10.00 + C$19.95 = C$29.95
5
Total Price = C$200.00 + C$29.95 = C$229.95
GST = C$10.00 | QST = C$19.95 | Total = C$229.95

Example 2: Service Invoice in Ontario

C$500 pre-tax service invoice in Ontario (HST 13%)

1
Pre-tax price = C$500.00
2
HST = C$500.00 x 0.13 = C$65.00 (federal 5% = C$25.00, provincial 8% = C$40.00)
3
Total Price = C$500.00 + C$65.00 = C$565.00
Federal GST = C$25.00 | Provincial = C$40.00 | Total = C$565.00

Example 3: Removing QST from a Quebec Receipt

C$229.95 tax-inclusive total in Quebec (GST+QST 14.975%)

1
Tax-inclusive total = C$229.95
2
Pre-tax = C$229.95 / (1 + 14.975/100) = C$229.95 / 1.14975 = C$200.00
3
GST = C$200.00 x 0.05 = C$10.00 | QST = C$200.00 x 0.09975 = C$19.95
4
Total Tax = C$29.95 | Check: C$200.00 + C$29.95 = C$229.95
Pre-Tax = C$200.00 | GST = C$10.00 | QST = C$19.95

❓ Frequently Asked Questions

What is the GST rate in Canada in 2025?+
Canada's federal Goods and Services Tax (GST) rate is 5% in 2025. This rate has been in place since January 1, 2008. It applies to most taxable goods and services sold in Canada. All provinces collect this 5% federal tax, either as standalone GST, as part of HST, or alongside a provincial tax like QST or PST.
What is the QST rate in Quebec for 2025?+
Quebec's QST rate is 9.975% in 2025. Combined with the federal GST of 5%, the total tax on most purchases in Quebec is 14.975%. Both GST and QST are calculated on the same pre-tax price, not on each other. GST is remitted to the CRA and QST is remitted to Revenu Quebec.
How do I calculate GST and QST on a purchase in Quebec?+
Multiply the pre-tax price by 5% for GST and by 9.975% for QST. For a C$200 item: GST = C$200 x 0.05 = C$10.00, QST = C$200 x 0.09975 = C$19.95, Total Tax = C$29.95, Total = C$229.95. The combined rate is 14.975%. This calculator handles the arithmetic instantly and shows each component separately.
Which Canadian provinces use HST and what are the 2025 rates?+
Five provinces use HST in 2025: Ontario at 13%, New Brunswick at 15%, Newfoundland and Labrador at 15%, Nova Scotia at 15%, and Prince Edward Island at 15%. Each HST rate combines a 5% federal component with a 8% or 10% provincial component. HST is administered entirely by the CRA, simplifying compliance for businesses in those provinces.
How do I remove GST and QST from a total price in Quebec?+
Divide the tax-inclusive total by 1.14975 to get the pre-tax price. For a C$229.95 total: Pre-tax = C$229.95 / 1.14975 = C$200.00. Then: GST = C$200 x 0.05 = C$10.00, QST = C$200 x 0.09975 = C$19.95. Use the Remove Tax mode on this calculator to skip the arithmetic and get the breakdown instantly.
What is the difference between GST and HST in Canada?+
GST is the standalone 5% federal tax collected in provinces that have not harmonized with Ottawa. HST is a blended rate where the federal 5% and a provincial component are combined into a single tax collected by the CRA. In Ontario, the 13% HST (5% federal + 8% provincial) is collected as one line item. In Quebec, GST (5%) and QST (9.975%) are listed separately on invoices.
Which Canadian provinces have no provincial sales tax?+
Alberta, Northwest Territories, Nunavut, and Yukon apply only the federal 5% GST with no provincial sales tax. Alberta is the only Canadian province with no PST, making it attractive for large purchases. The three territories (NWT, Nunavut, Yukon) also levy no territorial sales tax. A C$10,000 purchase in Alberta costs C$10,500 total, compared to C$11,498 in Quebec.
Are groceries exempt from GST and QST in Canada?+
Most basic groceries are zero-rated for GST/HST, meaning they are taxed at 0%. This covers most unheated food such as produce, bread, meat, and dairy. Carbonated beverages, candy, snack foods, and restaurant meals are taxable at the full rate. Quebec applies similar QST exemptions for basic food, though some specific items like bottled water over a certain size are treated differently.
How do input tax credits work for GST and QST in Canada?+
Registered businesses can claim input tax credits (ITCs) to recover GST paid on business expenses. For QST in Quebec, the equivalent is called an input tax refund (ITR) claimed on the QST return filed with Revenu Quebec. To claim an ITC or ITR, you need the exact tax amount from each invoice. The Remove Tax mode on this calculator helps identify the precise GST and QST amounts when only the total is shown on a receipt.
What is the combined tax rate in British Columbia in 2025?+
British Columbia's combined rate is 12% in 2025: 5% federal GST plus 7% provincial PST. Unlike Ontario, BC did not permanently harmonize its PST with the GST. They are two separate taxes with different rules, exemptions, and remittance processes. The GST is remitted to the CRA while the BC PST is remitted to the BC Ministry of Finance.
How is QST different from PST in other Canadian provinces?+
QST (Quebec Sales Tax) is structured much like the GST with a full input tax refund mechanism for businesses, making it more like a value-added tax. BC's PST, Saskatchewan's PST, and Manitoba's RST are simpler retail sales taxes with fewer ITC-style refunds and different exemption lists. QST is administered by Revenu Quebec, while other provinces administer their PST through their own finance departments independently of the CRA.
How often do Canadian provincial tax rates change?+
Canadian provincial tax rates are relatively stable. The federal GST rate has not changed since 2008. Quebec's QST rate has been 9.975% since 2013. HST rates in Atlantic provinces and Ontario have been unchanged for many years. Provincial PST rates change only through specific legislation. The rates in this calculator reflect the 2025 combined rates as published by the Canada Revenue Agency and Revenu Quebec.
