How Sales Tax Works in Canada

Canada does not have one universal sales tax rate. Instead of this, buyers pay different taxes depending on where goods or services are purchased. The Canadian sales tax system consists of four primary components:

Goods & Services Tax (GST)

GST is the federal sales tax or a federal value-added tax charged across Canada. It applies at a standard rate of 5% in some provinces such as Alberta, Northwest Territories(NWT), Nunavut, and Yukon. It is collected by the Government of Canada or the Canada Revenue Agency.

Territories with GST Only

Three territories have no provincial or territorial sales tax, only the federal GST:

• Alberta: 5%
• Northwest Territories: 5%
• Nunavut: 5%
• Yukon: 5%

Harmonized Sales Tax (HST)

Some provinces like British Columbia, Saskatchewan, Manitoba, and Quebec have combined their provincial sales tax (13% & 15%) with federal GST into one single tax known as HST. In these provinces, customers pay only one combined rate of HST instead of separate taxes.

For example, in Ontario, 13% HST is applied with 5% federal GST plus 8% provincial sales tax. In New Brunswick, Newfoundland and Labrador, Nova Scotia, and PEI, 15% HST is charged with 5% federal GST plus 10% provincial tax.

HST Provinces (Harmonized Sales Tax)

5 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

Provincial Sales Tax (PST)

Some provinces such as British Columbia, Manitoba, and Saskatchewan apply their own provincial sales tax rates separately combined with the 5% federal GST. Businesses must calculate and collect both taxes separately. For example, BC collects 7% PST with 5% Federal GST, and combines 12%. Same as, Saskatchewan applies 5% federal GST with 6% PST tax and a combined total of 11% PST+GST.

GST + PST Provinces

4 provinces charge separate federal and provincial sales taxes. The GST is 5% but provincial PST added on top:

• British Columbia(BC): 5% GST + 7% PST = 12% total
• Manitoba(MB): 5% GST + 7% PST = 12% total
• Quebec(QC): 5% GST + 9.975% QST = 14.975% total
• Saskatchewan(SK): 5% GST + 6% PST = 11% total

Quebec Sales Tax (QST)

Quebec uses works on its own provincial tax system known as the Quebec Sales Tax (QST), which is applied alongside the federal GST. For example, it is charged at 9.975% QST plus 5% GST and combined 14.975%.

How to Use This Canada GST HST Tax Calculator

Our calculator offers two calculation modes to meet your needs: Add Tax and Reverse Tax

Mode 1: Sales Tax Calculator (Forward Calculation)

You can use this option when you know the price before tax and want to calculate the total after tax:

• Choose the province where the purchase is made
• Enter the pre-tax price of the item or service
• See the GST/HST/PST/QST amount, and total after tax

Mode 2: Calculate Reverse Sales Tax

Use this option when you know the total after tax and want to find the pre-tax or reverse tax:

• Choose the province where the purchase was made
• Enter the total amount you paid including all taxes
• See the GST/HST/PST/QST amount, and amount before tax

How is Add Sales Tax Calculated?

If you know the price before tax, the calculator displays:

• Federal GST
• Provincial Tax (PST, QST, or HST)
• Total Tax Charged
• Final Amount After Tax

This is ideal when estimating the total cost of purchases or preparing customer invoices.

How is Reverse Sales Tax Calculated?

If you only know the final amount paid, the calculator works backwards to estimate:

• Original purchase price
• GST amount
• Provincial tax amount
• Combined sales tax included in the payment

This feature is useful when reviewing receipts, expense claims, reimbursements, or accounting records.

Why Provincial Tax Rates Are Different

In Canada, each province has the authority to determine whether it will apply the HST (Harmonized Sales Tax) system or use its own separate provincial sales tax.

• Some provinces charge only the federal GST.
• Others apply both GST and PST.
• Several provinces use one combined HST rate.
• Quebec applies GST together with QST.

Because of these differences, using the correct provincial tax rate is essential for accurate pricing, invoicing, and tax reporting. Here is the breakdown of which province uses which type of tax and what the rates of these different types of taxes are.

How to Calculate Sales Tax Formulas and Steps

Calculating the Add Sales Tax

These formulas are used to calculate the pre-tax price and want to calculate the tax amount and final price.

GST Amount

Provincial Tax Amount (PST/QST)

HST Amount

Total Price (Including Tax)

Example: Ontario: 13% HST

Pre-Tax Price: $100.00

Calculating the Reverse Sales Tax

These formulas are used to know the total amount (the original price before tax).

Pre-Tax Price

Total Tax Included

Example: Ontario: 13% HST

Total Price: $113.00

Example: British Columbia: 5% GST + 7% PST

Total Price: $112.00

Must-Know Tax Terminologies for Canadian Businesses

The Small Supplier Exemption Threshold ($30,000 Rule)

According to the CRA rules, business owners selling taxable goods or services do not need to register for or collect GST/HST if their gross taxable revenue across four consecutive calendar quarters is $30,000 CAD or less. Once revenue goes over the threshold of $30,000, GST/HST registration is compulsory for businesses.

Input Tax Credits (ITCs)

GST/HST-registered businesses that collect taxes on sales can claim Input Tax Credits (ITCs) to recover the GST/HST paid on eligible business operating expenses such as office rent, commercial software, equipment, and office supplies.

ITC can be calculated using the following formula:

In provinces where PST is applicable, such as British Columbia, Saskatchewan, and Manitoba, PST paid on general business operating expenses is usually not recoverable under the federal GST/HST system. Only GST, HST, and eligible QST amounts can generally be claimed through the applicable tax programs.

Place-of-Supply Rules

For cross-provincial sales, the applicable tax rate depends on the customer's location rather than the seller's business location.

For example, if a freelancer located in Alberta provides consulting services to a client in Nova Scotia, the freelancer must charge the 15% Nova Scotia HST, even though Alberta only applies the 5% federal GST.

Zero-Rated vs. Exempt Supplies

Supply Type	Examples	GST/HST Charged	Input Tax Credits (ITCs)
Zero-Rated Supplies (0%)	Basic groceries, prescription drugs, qualifying medical devices, export goods	No (0%)	Yes
Exempt Supplies	Residential rent, music lessons, most health and dental services, financial services	No	No
