1. What is Quebec Sales Tax?

Quebec has a dual sales tax system consisting of the federal Goods and Services Tax (GST) and the provincial Quebec Sales Tax (QST). These taxes are applied to most goods and services sold in the province.

2. How Does the Calculator Work?

The calculator uses the Quebec sales tax formula:

Where:

• \( Amount \) — The pre-tax amount in Canadian dollars
• \( GST \) — Federal Goods and Services Tax rate (currently 5%)
• \( QST \) — Quebec Sales Tax rate (currently 9.975%)

Explanation: The QST is applied on the price after GST has been added, making the effective combined tax rate slightly higher than the simple sum of both rates.

3. Importance of Accurate Tax Calculation

Details: Proper sales tax calculation is essential for businesses to remain compliant with Quebec tax laws and to accurately price goods and services for consumers.

4. Using the Calculator

Tips: Enter the pre-tax amount in CAD, the GST rate (default is 0.05), and QST rate (default is 0.09975). All values must be positive numbers.
