Basic Rules for Applying the GST/HST and QST

Coronavirus (COVID-19)

Click Coronavirus Disease (COVID-19) to see whether the measures adopted by Revenu Québec apply to the information on this page.

The most common consumption taxes for 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 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 between the federal and Québec governments, Revenu Québec administers the GST/HST in Québec in accordance with the rules set by the federal government.

Accordingly, we receive and process 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 us 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).


Québec businesses that are GST/HST registrants must collect the HST on sales they make in participating provinces (New Brunswick, Newfoundland and Labrador, Nova Scotia, Ontario and Prince Edward Island).

To find out whether you need to register your business for the GST/HST and QST, click Registering for the GST and QST.
