Canada GST/HST Calculator & Rate
Add Canadian GST/HST to a net price or take it out of a gross (tax-inclusive) amount. Pick the province or territory of supply to apply GST, HST and any provincial sales tax, using the CRA's rate table (verified 2026-09-25). All math runs locally in your browser.
Canada GST/HST calculator
Type an amount into any of the three boxes; the other two follow at the rate you pick.
GST/HST = 100.00 × 5% = 5.00; gross = 100.00 + 5.00 = 105.00
Worked in whole cents: the tax is rounded to the nearest cent (half a cent goes up) and the other amount is the difference, so the boxes always add up. From a gross amount the tax is gross × rate ÷ (100 + rate); from a typed tax amount the net is worked back and your tax amount stays as typed. Your tax authority may set its own rounding rules for invoices.
How much is GST/HST in Canada?
The federal GST in Canada is 5%. In the HST provinces a single harmonized sales tax applies instead: 13% in Ontario, 14% in Nova Scotia and 15% in New Brunswick, Newfoundland and Labrador and Prince Edward Island. British Columbia (7% PST), Manitoba (7% RST), Quebec (9.975% QST) and Saskatchewan (6% PST) charge a separate provincial sales tax on top of the 5% GST; Alberta, Northwest Territories, Nunavut and Yukon charge only the GST.

Canada GST/HST worked examples
Add GST/HST: gross = net × (1 + rate ÷ 100). Extract GST/HST: tax = gross × rate ÷ (100 + rate), and net = gross − tax.

How to calculate GST/HST on a Canadian invoice
- Find the place of supply. The CRA: "The rate of tax to charge depends on the place of supply. This is where you make your sale, lease, or other supply." For goods you deliver, the place of supply is the province in which the goods are delivered (CRA place-of-supply rules).
- Apply that province's rate. 5% GST if the supply is made in a non-participating province; HST of 13% in Ontario, 14% in Nova Scotia and 15% in New Brunswick, Newfoundland and Labrador and Prince Edward Island.
- Keep provincial sales tax separate. Where PST, RST or QST also applies, the CRA says: "calculate the GST on the price without the PST."
- Show the tax on the invoice. The CRA says to show "the GST/HST rate that applies to the supply" and "the amount paid or payable and the GST/HST amount as separate lines or a clear statement that the total amount paid or payable includes GST/HST". "If HST applies, show the total HST rate. Do not show the federal and provincial parts separately." (CRA)
Example, a $1,000.00 sale: delivered in Ontario, HST 13% = $130.00, total $1,130.00. Delivered in Manitoba, GST 5% = $50.00 on the price without the RST, plus RST 7% = $70.00 (Manitoba: the RST "is calculated on the selling price, before the GST (Good and Services Tax) is applied"; gov.mb.ca), total $1,120.00.
The calculator above applies a provincial sales tax to the net price. Check the province's own rules for your supply. What else a Canadian invoice must show is on the Canada GST/HST invoice requirements page.

What is the GST/HST rate in Canada in 2026?
The federal GST in Canada is 5%. In the HST provinces a single harmonized sales tax applies instead: 13% in Ontario, 14% in Nova Scotia and 15% in New Brunswick, Newfoundland and Labrador and Prince Edward Island. British Columbia (7% PST), Manitoba (7% RST), Quebec (9.975% QST) and Saskatchewan (6% PST) charge a separate provincial sales tax on top of the 5% GST; Alberta, Northwest Territories, Nunavut and Yukon charge only the GST. Source: Canada Revenue Agency (canada.ca): GST/HST rates by province, verified 2026-09-25. Rates change, so confirm against the linked source before filing anything.
How do I add GST/HST to a net price?
Multiply the net amount by (1 + rate ÷ 100). At 5%, a net price of 100.00 becomes 105.00 gross, of which 5.00 is GST/HST. The calculator on this page does it with Canada's verified rates preloaded.
How do I work out the GST/HST included in a gross price?
Multiply the gross (tax-inclusive) amount by rate ÷ (100 + rate), then subtract the result to get the net price. At 5% the share is 5/105 (about 4.7619%): a gross price of 100.00 contains 4.76 GST/HST and 95.24 net. Type the gross amount into the calculator's gross box to do this for any amount.
How do I calculate GST/HST on a Canadian invoice?
Find the place of supply (the province where you make the sale) and apply its rate: 5% GST in a non-participating province, or HST of 13% (ON), 14% (NS) or 15% (NB, NL, PE). Where a provincial sales tax also applies, the CRA says to calculate the GST on the price without the PST. On the invoice, the CRA says to show the GST/HST rate that applies, and the amount payable and the GST/HST amount as separate lines or a clear statement that the total includes GST/HST; for HST, show the total HST rate, not its federal and provincial parts.
