Quebec sales tax rate in 2026
Quebec charges two sales taxes: the 5% federal GST plus a 9.975% QST, for a combined 14.975%. The QST is calculated on the pre-GST price, so the two simply add together.
On common amounts at 14.975%: $10 → C$1.50 tax (C$11.50 total) · $50 → C$7.49 tax (C$57.49 total) · $100 → C$14.97 tax (C$114.97 total) · $1,000 → C$149.75 tax (C$1149.75 total).
GST and QST in Quebec
In Quebec the 5% GST and the 9.975% QST are listed separately on your receipt. Both are charged on the pre-tax price, so on a $100 item you pay C$5.00 GST and C$9.97 QST, C$14.97 in total tax. The calculator splits the two for you.
Enter any amount above to add Quebec sales tax, or switch to Remove tax to find the pre-tax price from a total that already includes it.
How Quebec sales tax is calculated
Sales tax is the price times the rate as a decimal. In Quebec a $100 item is 100 × 0.14975 = C$14.97 in tax, for a C$114.97 total. To work backwards from a tax-included total, divide by 1.14975 — the calculator's Remove tax mode does this in one step and shows the GST and QST portions.
QST is calculated before GST, not on top of it
The most common mix-up with Quebec sales tax: QST is not charged on the price plus GST — both taxes are calculated separately on the same pre-tax subtotal, then added together. On a $100 purchase: $100 × 5% = C$5.00 GST, and $100 × 9.975% = C$9.97 QST — for a total of C$114.97 (14.975% combined). QST is never applied to a GST-inclusive amount.
Two Quebec-specific nuances worth knowing: insurance premiums carry a separate 9% special tax (not GST or QST), and used-vehicle sales between individuals are taxed on the higher of the sale price or the vehicle's estimated value, with different rules for private sales versus dealers. Neither applies to a standard retail purchase, which is what this calculator computes.
