Province or territory

Price with sales tax

$113.00

HST at 13%: $13.00

Sales tax amount: $13.00
Price before sales tax: $100.00

What this means

Sales tax adds $13.00 to every $100.00 you spend. It’s the same rate whatever you earn, so it takes a bigger share of a smaller income.

Quick sales tax sums at 13%

Add sales tax: multiply the price by 1.13.
Remove sales tax: divide the price by 1.13.
sales tax in a price that includes it: 13/113 of the price.

Assumptions in this estimate

Businesses must register for GST/HST once their taxable sales go over $30,000 in four calendar quarters in a row.
Basic groceries, prescription drugs and some other items are zero-rated, so no GST or HST is charged on them. Provincial sales taxes have their own exemptions.

Sales tax by province and territory

Province or territory	Tax	Total
Alberta, Northwest Territories, Nunavut, Yukon	5% GST	5%
British Columbia	5% GST + 7% PST	12%
Manitoba	5% GST + 7% RST	12%
New Brunswick, Newfoundland and Labrador, PEI	15% HST	15%
Nova Scotia	14% HST	14%
Ontario	13% HST	13%
Quebec	5% GST + 9.975% QST	14.975%
Saskatchewan	5% GST + 6% PST	11%

Each tax is charged on the price before tax, so the taxes are added together rather than charged on each other. Nova Scotia’s HST fell from 15% to 14% on April 1, 2025.

Working it out

Adding tax: price × (1 + the total rate), for example × 1.13 in Ontario
Removing tax: price ÷ (1 + the total rate), for example ÷ 1.13 in Ontario

The calculator rounds each tax to the cent.

Frequently asked questions

What's the difference between GST, HST and PST?

GST is the 5% federal tax charged across Canada. Five provinces combine it with their own tax into one harmonized sales tax (HST). British Columbia, Saskatchewan, Manitoba and Quebec charge their own provincial tax (PST, RST or QST) separately, on top of the GST.

How do I calculate HST in Ontario?

Multiply the price by 1.13 to add Ontario's 13% HST. So $100 becomes $113. To remove it, divide by 1.13.

How is Quebec sales tax calculated?

Quebec charges the 5% GST and 9.975% QST, both on the price before tax, so 14.975% in total. On $100, that's $5 GST and $9.98 QST, for $114.98.

Which purchases have no GST or HST?

Some are zero-rated, so no GST or HST is charged, such as basic groceries, prescription drugs, certain medical devices and feminine hygiene products. Provincial sales taxes have their own exemptions.

When does a business have to register for GST/HST?

Once its taxable sales go over $30,000 in four calendar quarters in a row. Below that, it's a small supplier and doesn't have to register.
