Basic Rules for Applying the GST/HST and QST

The most common consumption taxes encountered by Québec residents are:

  • the goods and services tax (GST), which is calculated at a rate of 5% on the selling price; and 
  • the Québec sales tax (QST), which is calculated at a rate of 9.975% on the selling price excluding the GST.

The GST and QST are collected on the sale or supply (This link will open a new window) of most goods and services.

The harmonized sales tax (HST) replaces the provincial sales tax and the GST in some provinces.

Administration of the GST/HST in Québec

Under an agreement reached by the federal and Québec governments, Revenu Québec administers the GST/HST in Québec in accordance with the rules set by the federal government.

Accordingly, Revenu Québec receives and processes applications for registration under the GST/HST system from all persons carrying on commercial activities in Québec.

Once registered, these persons continue to deal with Revenu Québec for all GST- and HST-related matters (including returns, remittances, rebate applications, audits, investigations, interpretation of laws and regulations, notices of objection, tax collection, and unfiled returns).

HST

Québec businesses that are GST/HST registrants (This link will open a new window) must collect the HST on supplies they make in participating provinces (New Brunswick, Nova Scotia, Newfoundland and Labrador, Ontario and Prince Edward Island).
