How Quebec Taxes Work

Quebec applies two separate taxes on most goods and services. The GST (Goods and Services Tax) is a federal tax of 5%, while the QST (Quebec Sales Tax) is a provincial tax of 9.975%. Worth noting: QST is calculated on the subtotal — not on the subtotal plus GST. The effective combined rate is 14.975%.

  • GST: 5% × subtotal
  • QST: 9.975% × subtotal (not on GST)
  • Tip (when applicable): calculated on subtotal — Quebec standard

All 13 provinces and territories, current 2026 rates

The calculator now covers all 10 provinces and 3 territories with rates current as of 2026. Nova Scotia dropped from 15% to 14% HST in April 2025 — that's already reflected here. Each region only shows the taxes that actually apply to it: Alberta, Yukon, Northwest Territories, and Nunavut display GST only. Ontario, Nova Scotia, New Brunswick, Newfoundland, and PEI show HST as a single combined rate. BC, Saskatchewan, and Manitoba show GST + PST as separate rows. Quebec shows GST + QST. No need to look up which tax structure your province uses — pick your region and the right rows appear.

Before/after tax modes work for all regions: enter the pre-tax price to see what you'll pay, or enter the final price to extract the tax breakdown. A convenience fee you see on a receipt is a common before/after use case — you paid $113.00, you need to know what the base was. What's not here: municipal taxes, fuel levies, alcohol surcharges, or any tax that varies by product category within a province. Those require a table lookup, not a calculator.

Frequently Asked Questions

Is QST calculated on top of GST?
No. In Quebec, QST (9.975%) is calculated on the subtotal only — not on the subtotal plus GST. This is a common misconception. Both the GST and QST are applied independently to the original pre-tax price, resulting in a combined effective rate of 14.975%.
What goods are exempt from GST and QST in Quebec?
Basic groceries (unprocessed food), prescription drugs, most medical devices, and certain financial services are exempt from both GST and QST. Residential rent is also generally exempt. Always verify with Revenu Québec for your specific situation.
Should I tip on the pre-tax or post-tax amount in Quebec?
The Quebec standard is to tip on the pre-tax subtotal. Quick tip: double the QST amount shown on your bill (2 × 9.975% ≈ 20%). It's fast and results in an appropriate tip without needing a calculator.
