Canada GST/HST Calculator
Add or remove GST/HST from an amount for any Canadian province or territory.
Canada charges a 5% federal GST everywhere, but many provinces combine it into a single Harmonized Sales Tax (HST), while others add their own separate Provincial Sales Tax (PST) or, in Quebec, the QST. This calculator uses the current combined rate for whichever province or territory you select.
Example
- With the default values shown above, this calculator returns: Net Amount ≈ CAD 100.00; Tax Amount ≈ CAD 13.00; Gross Amount ≈ CAD 113.00.
Frequently Asked Questions
Why do rates differ by province?
GST is a flat 5% federal tax everywhere in Canada. Some provinces harmonize it with their own sales tax into a single HST rate; others (Alberta, the territories) charge only the 5% GST; others add a separate PST or QST on top.
Are all goods and services taxed?
No — some items (like basic groceries and prescription drugs) are zero-rated or exempt from GST/HST. Check the CRA’s guidance for your specific goods or services.
