How the Quebec Sales Tax Calculator Works

This calculator estimates the sales tax breakdown for purchases in Quebec. Enter a before-tax amount (default) or switch to tax-included to reverse-calculate the subtotal.

  • Standard calculation: Enter your before-tax amount. Whether you are shopping in Montreal, Quebec City, or Laval, the calculator automatically applies the 5% GST and the 9.975% QST to give you the exact final cost.
  • Reverse calculation (tax included): Turn on “Amount includes tax?”. If you have a total receipt, the tool works backward to accurately separate the complex 14.975% combined tax into its base price, GST, and QST components.

Understanding GST and QST in Quebec

The system consists of 5% TPS and 9.975% TVQ. Historically, TVQ was charged on top of the TPS ('tax on tax'), but this was abolished in 2013. Now, both taxes are calculated directly on the base subtotal.

In Quebec, shelf prices are strictly displayed before tax. When you reach the cash register, you will typically see the 5% GST and 9.975% QST added as two separate lines on your receipt. Use the 'Amount includes tax?' toggle to easily reverse-calculate a final bill.

How to calculate sales tax in Quebec (before tax and tax included)

The exact formula used in Quebec is: Total = Amount × 1.14975. To perform a reverse calculation and find the pre-tax sticker price from a receipt, you simply divide the final total by 1.14975.

Total including tax = Before-tax amount × (1 + 14.975%)
Before-tax amount = Total including tax ÷ (1 + 14.975%)

  • Most other goods, services, restaurant meals, and digital subscriptions are taxed at the full 14.975% rate.
