GST/HST calculator by province

Add GST/HST to a price, or work backwards from a total that already includes tax. Pick the province, enter an amount, and you'll get the tax and total right away. Nothing you type leaves your browser.

How it works

• Add tax: GST/HST = amount × rate, total = amount + tax. In Ontario, $1,000 + 13% = $1,130.
• Remove tax: amount before tax = total ÷ (1 + rate). In Ontario, $1,130 ÷ 1.13 = $1,000, so the HST is $130.
• For HST provinces, the result also splits the tax into the 5% federal part and the provincial part.
• Amounts are rounded to the cent, so they may differ from an invoice by a cent or two.

FAQ

What is the GST/HST rate in my province?

5% GST in Alberta, British Columbia, Manitoba, Quebec, Saskatchewan and the three territories. HST is 13% in Ontario, 14% in Nova Scotia (since April 1, 2025), and 15% in New Brunswick, Newfoundland and Labrador, and Prince Edward Island.

How do I take GST/HST out of a total (reverse calculation)?

Divide the tax-included total by 1 plus the rate. For example, in Ontario $113 ÷ 1.13 = $100 before tax, so the HST is $13. Don't just multiply the total by 13%; that overstates the tax.

Which province's rate do I charge as a freelancer?

It depends on the place-of-supply rules, not only where you live. For many services, the rate is based on where your client is, so an Ontario freelancer billing a Nova Scotia client may charge 14% HST rather than 13%. Check the CRA's place-of-supply guidance for your situation.

Does this include PST or QST?

No. This calculator covers GST/HST only. BC, Manitoba, Saskatchewan and Quebec have separate provincial sales taxes with their own rules and registrations.

Do I have to charge GST/HST at all?

Not until you're registered. Most small businesses have to register once their taxable revenue goes over $30,000 in a single calendar quarter or over the last four consecutive quarters (the small supplier threshold). You can also register voluntarily.
