Canada GST/HST Calculator
Calculate Canadian GST, HST, PST and QST by province. Federal GST is 5% — combined rates range from 5% to 15% depending on your province.
Canada GST/HST Calculator — Complete Guide to Canadian Sales Tax
Canada's sales tax system is a patchwork of federal and provincial taxes that varies significantly by province. The federal Goods and Services Tax (GST) is 5% and applies across Canada. However, most provinces layer additional provincial sales taxes on top — either as a combined Harmonised Sales Tax (HST), a separate Provincial Sales Tax (PST), or Quebec's own QST system.
This calculator covers all 13 provinces and territories. Simply select your province to get the correct combined rate — from 5% in Alberta, the Northwest Territories, Nunavut and Yukon (GST only) up to 15% in the Atlantic provinces (New Brunswick, Newfoundland and Labrador, Nova Scotia, and Prince Edward Island).

Worked Examples by Province
GST/HST +
Ontario (13% HST): C$100.00 before tax × 1.13 = C$113.00 total. HST = C$13.00.
GST/HST −
Quebec (14.975% GST+QST): C$114.975 total ÷ 1.14975 = C$100.00 before tax. Tax = C$14.975.

GST/HST Registration Threshold (2025)
Businesses and self-employed individuals must register for GST/HST with the Canada Revenue Agency (CRA) when their worldwide taxable revenues exceed C$30,000 in any single calendar quarter or over four consecutive calendar quarters. This threshold applies per business, not per location.
Once registered, you must charge and collect GST/HST on taxable sales, file GST/HST returns (monthly, quarterly, or annually depending on annual revenues), and remit the net tax to the CRA. You can claim Input Tax Credits (ITCs) to recover GST/HST paid on business purchases.
Filing GST/HST Returns in Canada
GST/HST return filing frequency depends on annual taxable revenues: annual filers (≤ C$1.5M), quarterly filers (C$1.5M–$6M), and monthly filers (> C$6M). Returns are filed electronically through the CRA's My Business Account or via NETFILE-compatible accounting software.
Quebec businesses also file a separate QST return with Revenu Québec via the Mon dossier portal. Both returns are typically due one month after the end of the reporting period. Input Tax Credits (ITCs for GST/HST) and Input Tax Refunds (ITRs for QST) work similarly — you deduct tax paid on purchases from tax collected on sales.
Frequently Asked Questions — Canadian GST/HST
- What is the GST rate in Canada?
- The federal Goods and Services Tax (GST) rate in Canada is 5%. This applies to most goods and services sold across Canada. Most provinces add provincial sales tax on top: Ontario and the Atlantic provinces use a combined HST (13–15%), BC and Manitoba add a separate 7% PST (total 12%), Quebec adds a 9.975% QST (total 14.975%), and Saskatchewan adds 6% PST (total 11%). Alberta, Yukon, Nunavut, and the Northwest Territories have no provincial sales tax, so only 5% GST applies.
- What is the difference between GST, HST, and PST?
- GST (Goods and Services Tax) is the federal 5% tax collected by the Canada Revenue Agency. HST (Harmonised Sales Tax) is a combined federal and provincial tax used in Ontario (13%), New Brunswick, Newfoundland and Labrador, Nova Scotia, and Prince Edward Island (all 15%) — collected together as one tax by the CRA. PST (Provincial Sales Tax) is a separate provincial tax charged in British Columbia (7%), Manitoba (7%), and Saskatchewan (6%) — collected by the province, not the CRA.
- What is the QST in Quebec?
- The Quebec Sales Tax (QST) is Quebec's provincial sales tax, currently 9.975%. It is administered separately by Revenu Québec. When combined with the 5% GST, the total tax rate in Quebec is 14.975%. Both taxes are charged on the same base (the selling price), so the combined effective rate is simply 5% + 9.975% = 14.975%.
- Do I have to charge GST/HST on all my sales?
- No. Some supplies are zero-rated (0% GST/HST — mainly basic groceries, prescription drugs, and most exports) or exempt (no GST/HST charged and no Input Tax Credits available — mainly financial services, health care, and residential rent). Zero-rated differs from exempt: zero-rated businesses still file returns and can claim ITCs on their purchases.
- How do I calculate HST in Ontario?
- Ontario's HST rate is 13%. To add HST: multiply the pre-tax price by 1.13. To remove HST from a tax-inclusive price: divide by 1.13. Example: C$500 × 1.13 = C$565 total; C$565 ÷ 1.13 = C$500 pre-tax.
- What is an Input Tax Credit (ITC)?
- An ITC is the GST/HST you paid on purchases and expenses used to make taxable supplies in your business. You can claim ITCs to reduce the GST/HST you owe on your returns. ITCs make GST/HST effectively a tax on the final consumer rather than on businesses — businesses act as collection agents for the CRA, not as the ultimate tax bearers.
- Do non-resident businesses need to register for Canadian GST/HST?
- Non-resident businesses selling digital services (software, streaming, downloads) to Canadians must register for the simplified GST/HST regime if their revenues from Canadian consumers exceed C$30,000 over 12 months. This applies regardless of whether the purchaser is a business or consumer. Non-resident businesses selling physical goods to Canadians may also have GST/HST obligations depending on the supply arrangement.
