Quebec GST and QST Rates

Quebec does not use the Harmonized Sales Tax (HST). Instead, it maintains a two-tiered sales tax system composed of the federal Goods and Services Tax (GST) and the provincial Quebec Sales Tax (QST).

Unlike other provinces, Revenu Québec administers both the federal and provincial portions. Businesses file a single combined sales tax return and make payments directly to Revenu Québec.

Quebec GST/QST Calculator Example

To calculate Quebec sales tax on a purchase, you calculate the 5% GST and the 9.975% QST independently on the pre-tax base price (the QST is not compounded on top of the GST). Here are common calculation examples using our Quebec GST/QST calculator:

Base PriceGST (5%)QST (9.975%)Combined Tax (14.975%)Total Price
$100.00 CAD$5.00 CAD$9.98 CAD$14.98 CAD$114.98 CAD
$500.00 CAD$25.00 CAD$49.88 CAD$74.88 CAD$574.88 CAD
$1000.00 CAD$50.00 CAD$99.75 CAD$149.75 CAD$1149.75 CAD

Is Quebec HST or GST/QST?

Quebec uses a GST/QST dual tax system rather than the Harmonized Sales Tax (HST). Although the administration is harmonized under Revenu Québec, QST remains legally distinct from the federal GST, and Quebec does not participate in the joint federal-provincial HST framework.
