GST/HST calculator
Add or remove GST/HST for any Canadian province. Quebec calculation includes QST. All math runs in your browser - we never see your numbers.
Rates as of June 2026. PST in BC, Saskatchewan, and Manitoba is administered provincially and not included above - see the provincial tax rates page.
How GST/HST works
GST is a 5% federal sales tax. Five provinces have harmonized their provincial sales tax with GST into a single HST - New Brunswick, Newfoundland and Labrador, Nova Scotia, Ontario, and PEI. As a registered business, you charge HST instead of separate GST and PST in those provinces. Quebec has GST plus a separate QST administered by Revenu Québec.
If you’re registered for GST/HST, you remit what you collect minus what you paid on business expenses (Input Tax Credits). See our GST/HST registration guide for the full mechanics.

Notes
- Place-of-supply rules determine which province’s rate applies - usually where the customer is, with exceptions for real property and certain services. CRA’s GST/HST Memorandum 3-3 has the details.
- Zero-rated supplies (most basic groceries, most prescription drugs, exports) are taxable at 0% - you don’t charge tax but you do claim ITCs on inputs.
- Exempt supplies (long-term residential rents, most financial services, most health services) are not taxable, and you don’t claim ITCs on inputs.
- Quick Method users use a different remittance rate - this calculator shows the customer-facing math, not your remittance amount.
FAQ
Why does Quebec show two rates?
Because GST and QST are separate taxes. Both are calculated on the pre-tax amount (QST is no longer applied on GST as of 2013). You charge them as one combined amount on the invoice but remit separately.
Does this work for invoicing?
The math is correct. For invoicing purposes, also display your GST/HST number (and QST number in Quebec) on the invoice - CRA requires it for any sale over $30.
