Worked example
$100 in Ontario and Quebec. Ontario charges 13% HST, so $100 × 13% = $13 and the total is $113.00. Quebec charges 5% GST ($5.00) plus 9.975% QST ($9.98), so the total is $114.98. To remove tax from $113 in Ontario, divide by 1.13 to get $100.00.

The same $1,000 laptop costs $1,050 in Alberta, $1,130 in Ontario and $1,149.75 in Quebec once sales tax is added.
Frequently asked questions
What is the difference between GST and HST?
GST is the 5% federal sales tax charged everywhere in Canada. In Ontario and the Atlantic provinces it is combined with the provincial tax into one harmonized sales tax, the HST, of 13%, 14% or 15%.
Which provinces charge PST or QST on top of GST?
British Columbia charges 7% PST, Manitoba 7% RST, Saskatchewan 6% PST and Quebec 9.975% QST, each on top of the 5% GST.
Which provinces have no provincial sales tax?
Alberta and the three territories (Yukon, Northwest Territories and Nunavut) charge only the 5% GST.
How do I remove HST from a total?
Divide the total by 1 plus the rate. In Ontario, $113 ÷ 1.13 = $100 before tax, so the HST is $13.
What is the HST rate in Nova Scotia?
14% since 1 April 2025. It was 15% from October 2016 to March 2025.
Which rate applies when I sell to another province?
For most goods and services, GST/HST is charged at the rate of the province where the supply is made, which is usually where the goods are delivered or the service is used. Pick that province in the calculator.
