Sales Tax in Quebec (2026)
Quebec charges the 5% federal GST plus the 9.975% Quebec sales tax (QST), a combined 14.975%. Since January 1, 2013, the QST is calculated on the price before GST, so there is no tax on tax.
- Both taxes are calculated on the pre-tax price: $100 × 5% = $5.00 GST and $100 × 9.975% = $9.98 QST, for $114.98 in total.
- Revenu Québec, not the CRA, administers both the GST and the QST for most businesses in Quebec.
- Businesses must register for the QST once taxable sales pass $30,000 over four consecutive calendar quarters, the same small-supplier threshold as the GST.

How to Calculate GST + QST in Quebec
Adding tax: a $1,000 purchase in Quebec carries $50.00 GST and $99.75 QST, for $149.75 in tax and a total of $1,149.75 ($1,000 × 1.1498).
Removing tax: a $250.00 receipt that includes tax works out to $250.00 ÷ 1.1498 = $217.44 before tax, so the tax paid was $32.56. Don't just take 14.975% off the total: that gives $212.56 and understates the tax.
