What is Canada GST/HST Calculator?

Canadian tax rates differ significantly by province — some charge GST only, others combine it with PST, and several provinces use a single Harmonized Sales Tax (HST). This calculator applies the correct rate for your province so every transaction is taxed accurately.

How to Use This Tool

1. Enter the pre-tax price of the product or service. 2. Input your province's combined tax rate (e.g., 13% for Ontario HST, 5% for Alberta GST only). 3. Calculate the tax amount and total price.

💡 Pro Tip: If you are a small supplier with under $30,000 CAD in annual revenue, you are not required to collect GST/HST. But once you cross that threshold, registration is mandatory. Track your revenue carefully and use this calculator to prepare!
