Canada GST & QST Calculator
Quickly calculate the Goods and Services Tax (GST) and Quebec Sales Tax (QST) on your purchases.
Calculate Your Canadian Sales Tax
Note on Rates: This calculator uses the current federal GST rate of 5% and Quebec’s QST rate of 9.975%. These rates are subject to change by the respective governments. For other provinces, only GST applies (QST is specific to Quebec), and many have HST (Harmonized Sales Tax) which combines federal and provincial taxes differently.
How to Use This Calculator & Understand GST/QST
Our GST/QST calculator is designed for simplicity. Just follow these steps:
- Enter Price Before Tax: Input the original price of the good or service.
- Select Province: Choose ‘Quebec’ if the purchase is being made in Quebec (where both GST and QST apply). Select ‘Other Canadian Provinces’ if only GST applies.
- Click ‘Calculate Taxes’: The calculator will instantly display the GST amount, QST amount (if applicable), total tax, and the final price including all taxes.
Understanding GST & QST:
The **Goods and Services Tax (GST)** is a federal tax applied across Canada, currently at 5%. The **Quebec Sales Tax (QST)** is a provincial tax exclusive to Quebec, currently at 9.975%. In Quebec, QST is generally calculated on the price *including* the GST, which means it’s a compound tax. Other provinces have different sales tax structures, often a Harmonized Sales Tax (HST) which combines the federal and provincial portions into a single tax rate.
