Planning a purchase or running a business in Canada? Our comprehensive Canada GST/HST Calculator helps you determine the exact sales tax amount for any transaction across all 13 provinces and territories. Whether you need to calculate the tax on a purchase, determine the pre-tax amount, or understand your total payable, this tool provides accurate CRA-compliant calculations based on the latest sales tax rates for 2025-2026.
Understanding sales tax is essential for consumers, businesses, and anyone making purchases in Canada. Our calculator supports both forward calculation (adding tax to a pre-tax amount) and reverse calculation (finding the pre-tax amount from a total). This flexibility makes it useful for budgeting, accounting, and tax planning purposes.
Understanding Canada's Sales Tax System
Canada has a unique sales tax system that varies by province and territory. There are three main types of sales taxes:
GST (Goods and Services Tax): A federal tax of 5% applied nationwide
HST (Harmonized Sales Tax): Combined federal and provincial tax in participating provinces
PST (Provincial Sales Tax): Separate provincial tax in non-participating provinces
Quick Fact: Five provinces use HST (combined rate), four provinces use GST + PST, and four territories use only GST with no provincial sales tax.
Canadian Sales Tax Rates by Province (2025-2026)
Here are the current sales tax rates for all provinces and territories. HST provinces have a combined rate, while GST+PST provinces have separate federal and provincial components.

HST Provinces (Harmonized Sales Tax)
Five provinces have harmonized their provincial sales tax with the federal GST, creating a single combined tax. The HST rates are:
New Brunswick: 15% HST (5% federal + 10% provincial)
Newfoundland and Labrador: 15% HST (5% federal + 10% provincial)
Nova Scotia: 14% HST (5% federal + 9% provincial)
Ontario: 13% HST (5% federal + 8% provincial)
Prince Edward Island: 15% HST (5% federal + 10% provincial)
GST + PST Provinces
Four provinces apply separate federal and provincial sales taxes. The GST is always 5%, with provincial PST added on top:
British Columbia: 5% GST + 7% PST = 12% total
Manitoba: 5% GST + 7% PST = 12% total
Quebec: 5% GST + 9.975% QST = 14.975% total
Saskatchewan: 5% GST + 6% PST = 11% total
Territories (GST Only)
Three territories have no provincial or territorial sales tax, only the federal GST:
Alberta: 5% GST only
Northwest Territories: 5% GST only
Nunavut: 5% GST only
Yukon: 5% GST only

GST (Goods and Services Tax) is a federal tax of 5% applied nationwide. HST (Harmonized Sales Tax) combines the federal GST with provincial sales tax into a single rate in participating provinces like Ontario (13%), New Brunswick (15%), and Nova Scotia (14%).
New Brunswick, Newfoundland and Labrador, and Prince Edward Island have the highest sales tax at 15% HST. Quebec follows at 14.975% (5% GST + 9.975% QST), and Nova Scotia is 14% HST.
Alberta, Northwest Territories, Nunavut, and Yukon have no provincial or territorial sales tax. Residents only pay the 5% federal GST on most purchases.
To calculate GST from a total amount, divide the total by 1.05 (for GST-only provinces) or use the formula: GST = Total × (5 ÷ Combined Rate). Our reverse calculator does this automatically.
Most goods and services are taxable, but some are zero-rated (like basic groceries) or exempt (like residential rent). Check CRA guidelines for specific items.
Quebec has 5% GST plus 9.975% QST (Quebec Sales Tax), for a combined rate of approximately 14.975%. The QST is administered by Revenu Québec separately from the federal GST.
Businesses must charge GST/HST on taxable sales, collect it from customers, and remit it to the CRA. You can claim input tax credits for GST/HST paid on business expenses. Use our calculator to determine correct amounts.
Nova Scotia reduced its HST from 15% to 14% effective April 1, 2025. This makes it the only Atlantic province with a 14% rate, while New Brunswick, Newfoundland and Labrador, and PEI maintain 15%.
