A $100 price tag is rarely a $100 purchase in Canada. GST, HST, PST and QST stack up differently in every province, and in Quebec the two taxes are calculated separately. Use this calculator to add tax to a pre-tax price, or strip the tax out of a price that already includes it.
How much tax will I pay?
Enter an amount and a province, then press “Calculate my tax”.
Rates are the 2026 GST, HST, PST and QST rates. In Quebec, GST and QST are each calculated on the pre-tax price and rounded separately.
How GST and HST are calculated
Every province and territory charges 5% GST, except the provinces that charge HST instead: Ontario 13%, Nova Scotia 14%, and New Brunswick, Newfoundland and Labrador, and Prince Edward Island 15%. British Columbia, Saskatchewan and Manitoba add a provincial sales tax on top of GST, and Quebec adds QST.
Ontario 13% HST; Quebec 5% GST plus 9.975% QST; British Columbia 5% GST plus 7% PST; Alberta 5% GST; Saskatchewan 5% GST plus 6% PST; Manitoba 5% GST plus 7% RST; Nova Scotia 14% HST; New Brunswick, Newfoundland and Labrador, and Prince Edward Island 15% HST; Yukon, Northwest Territories and Nunavut 5% GST.
In Quebec, GST and QST are calculated separately. Each tax is worked out on the pre-tax price and rounded to the nearest cent on its own line. On a $100 pre-tax price, GST is $5.00 and QST is $9.98 (9.975% of $100, rounded), for a total of $114.98. QST is not charged on the GST.
To remove tax from a tax-included price, the calculator divides the price by one plus the combined tax rate. That gives the pre-tax price, and each tax is then worked out from that price, so the parts add back up to the price you entered.
The toggle labelled Include PST / QST where it applies is on by default. Turn it off to see the GST or HST alone, for example when an item is exempt from provincial tax.
Frequently asked questions
What is the difference between GST and HST?
GST is the 5% federal tax charged on its own in Alberta and the territories. HST is the combined federal and provincial tax charged as a single rate in Ontario (13%), Nova Scotia (14%), and New Brunswick, Newfoundland and Labrador, and Prince Edward Island (15%).
Why is Nova Scotia HST 14% and not 15%?
Nova Scotia lowered its HST rate from 15% to 14% on April 1, 2025. New Brunswick, Newfoundland and Labrador, and Prince Edward Island still charge 15%.
Is QST charged on top of GST in Quebec?
No. In Quebec, GST (5%) and QST (9.975%) are each calculated on the pre-tax price and rounded separately, for a combined 14.975%. On a $100 pre-tax price that is $5.00 GST plus $9.98 QST, for a $114.98 total.
How do I remove tax from a price?
Choose Remove tax, enter the tax-included price and your province. The calculator divides by one plus the tax rate to find the pre-tax price, then works out each tax from that price. A $113.00 price in Ontario is $100.00 before tax.
Do I pay PST on top of GST in British Columbia?
Yes, if the item is taxable. British Columbia charges 5% GST plus 7% PST, for a combined 12%. Saskatchewan charges 5% GST plus 6% PST (11% combined) and Manitoba charges 5% GST plus 7% RST (12% combined). Turn the PST and QST toggle off to see the GST or HST alone.
Methodology and sources
Methodology: Rates are the 2026 GST, HST, PST and QST rates published by the Canada Revenue Agency (CRA). Quebec GST and QST are calculated on the pre-tax price and rounded separately, as CRA requires. This calculator does not handle zero-rated or exempt goods, GST/HST rebates, or the place-of-supply rules for services delivered across provincial borders.
