Question 1

What is the GST/HST rate in each Canadian province for 2025?

Accepted Answer

Canadian sales tax rates for 2025: Ontario (HST 13%), Nova Scotia (HST 15%), New Brunswick (HST 15%), Newfoundland & Labrador (HST 15%), Prince Edward Island (HST 15%), British Columbia (GST 5% + PST 7% = 12%), Manitoba (GST 5% + PST 7% = 12%), Saskatchewan (GST 5% + PST 6% = 11%), Quebec (GST 5% + QST 9.975% = 14.975%), Alberta, Yukon, Northwest Territories, and Nunavut (GST 5% only).

Question 2

How do I reverse-calculate GST/HST from a total amount?

Accepted Answer

To back out HST from a total (e.g., Ontario 13% HST): divide the total by 1.13 to get the pre-tax amount, then subtract to find the tax. Example: $113 total ÷ 1.13 = $100 pre-tax, so HST = $13. Our GST/HST calculator does this automatically — just select "Reverse (back out tax)" mode and enter the total amount.

Question 3

Does this calculator handle inter-provincial sales tax?

Accepted Answer

Yes. For GST/HST purposes, the tax rate is determined by the province where the customer receives the goods or service (place of supply rules). Select the customer's province in the calculator to apply the correct rate. Note: PST in BC, Manitoba, and Saskatchewan, and QST in Quebec, are separate provincial taxes with their own registration requirements and do not follow the federal place-of-supply rules in the same way.
