GST/HST Calculator for Quebec
Calculate your tax obligations using CRA place-of-supply rules for goods, services, and digital products.
Quebec has a dual tax system — GST administered by CRA and QST administered by Revenu Québec. Quebec businesses collect both taxes on sales within Quebec. When selling to clients outside Quebec, GST or HST applies depending on the destination province. QST generally does not apply to sales outside Quebec. This calculator covers the GST/HST side of cross-provincial transactions.

Charging GST/HST in Quebec: FAQ
What sales tax do I charge a Quebec client?
On sales to customers in Quebec, you charge 14.975% in total: 5% GST plus 9.975% QST.
What rate do I charge a client in another province?
For most sales, CRA's place-of-supply rules mean you charge the rate of the customer's province, not your own. For services it is generally based on the client's address, and for goods on where they are delivered. A Quebec business invoicing an Ontario client usually charges 13% HST, and an Alberta client 5% GST. Use the calculator above to get the exact rate for any province pair.
Do I charge QST to clients outside Quebec?
Generally no. QST applies to taxable sales made within Quebec. When you invoice clients in other provinces, you follow GST/HST place-of-supply rules instead of charging QST.
