About Quebec Sales Tax
Quebec charges the federal GST of 5% and a provincial tax known as QST (Quebec Sales Tax or TVQ - Taxe de vente du Québec) at a rate of 9.975%. The combined effective sales tax rate in Quebec is 14.975%.
The QST is administered by Revenu Québec on behalf of both the provincial and federal governments. Unlike other provinces, QST is calculated on the pre-tax base price, and then the GST is also calculated on the base price, bringing the combined total multiplier to exactly 1.14975.
There are no municipal sales taxes in Montreal, Quebec City, or Laval. The rate is uniform across the entire province.
Tax Rates in Major Quebec Cities
* Unlike in the US, Canadian provinces apply sales tax uniformly across all municipalities. City-level or county-level surcharges do not exist in Canada.
