The rate depends on the place of supply — normally where the goods are delivered or the service is performed, not where the seller is located. Some items (basic groceries, prescription drugs, exports) are zero-rated or exempt and carry no tax at all.

Frequently asked questions
What are the GST/HST rates in each province?
The federal GST is 5% everywhere. Five provinces use a harmonized HST instead: Ontario 13%, Nova Scotia 14% (cut from 15% on April 1, 2025), and New Brunswick, Newfoundland and Labrador, and PEI at 15%. BC adds 7% PST, Saskatchewan 6% PST, Manitoba 7% RST, and Quebec 9.975% QST on top of the 5% GST. Alberta and the three territories charge GST only.
How do I remove GST/HST from a total that includes tax?
Divide the total by 1 plus the combined rate, which gives the pre-tax price; the difference is the tax. For example, a $113 total in Ontario is $113 ÷ 1.13 = $100 before tax, with $13 of HST. This calculator does it in either direction — choose "Remove tax".
Is Quebec QST charged on top of GST (tax on tax)?
No. Since January 1, 2013 the 9.975% QST is calculated on the price before GST, the same base as the GST itself. A $100 purchase in Quebec carries $5.00 GST + $9.98 QST = $114.98 total, a combined rate of 14.975%.
What is the difference between zero-rated and exempt items?
Both carry no tax for the buyer, but they differ for sellers. Zero-rated supplies (basic groceries, prescription drugs, exports) are taxable at 0%, so the seller can still claim input tax credits on its costs. Exempt supplies (residential rent, most health care, most financial services) are outside the system, and the seller cannot recover GST/HST paid on inputs.
When does a business have to register for GST/HST?
Once worldwide taxable supplies exceed $30,000 over four consecutive calendar quarters (or in one quarter), you must register and start charging GST/HST. Below that you are a "small supplier" and registration is optional — though registering voluntarily lets you claim input tax credits. Provincial PST/QST registration is separate, with its own rules.
