La Belle Province's Unique Tax Landscape
Doing business in Quebec requires knowledge of two different tax authorities.
1. The Combined Rate
Quebec has a total tax rate of 14.975%. This is calculated as:
- 5% GST (Federal)
- 9.975% QST (Provincial)
2. Revenu Québec Administration
In other provinces, the CRA handles GST/HST. In Quebec, Revenu Québec handles both the GST and the QST for all businesses located in the province. This means you file one single return to one agency.
3. Registration Requirements
If you sell to customers in Quebec from another province, you may need to register for QST specifically if your sales exceed $30,000, similar to the federal rule.
4. Zero-Rated vs. Exempt in Quebec
Most items that are zero-rated for GST (like basic groceries) are also zero-rated for QST, keeping the math simple for retailers.
