Buying or selling in Canada? GST starts with the standard 5% rate. Calculate it exactly here — free, in your browser, no signup. That is the federal GST.

“Add tax” starts from a net price. “Remove tax” works backwards from a total that already includes tax. This is the STANDARD rate in Canada — reduced rates, zero-rating and exemptions may apply to specific items. If you know a different rate applies to your item, type it into the rate field.

Provinces and territories

Canada's 5% GST is only half the story in most provinces: five provinces blend it into a single HST, four add a separate provincial tax, and Alberta and the three territories charge GST only. Pick your province or territory — each calculator opens with that province's combined rate already entered, with the breakdown shown.

How to calculate GST on a Canadian invoice in 3 steps

Enter your amount. Type the price on the invoice you are working with — either before tax or tax-inclusive, depending on what you have.
Pick the rate and direction. The 5% standard rate is pre-filled and editable; choose “Add tax” or “Remove tax”.
Read the split instantly. You get the net amount, the exact tax, and the gross total — ready to quote, invoice, or check a receipt against.

Why getting the Canada split right matters

Tax is the part of the price most people get wrong, because the headline rate is rarely the whole story: reduced rates, zero-rating and exemptions all change what applies to a given item. This calculator starts from the standard rate — and if your item qualifies for a different rate, type it in and it calculates that instead.

Canada GST FAQ

The standard rate is 5%. That is the federal GST. Most provinces add their own tax or use HST at 13%–15%, so the combined rate depends on the province — type a combined rate into the field if you know it.

Multiply the net price by the rate and add it on: a C$1,000.00 item at 5% gives C$50.00 of tax and a C$1,050.00 total. In the calculator, choose “Add tax”, enter the amount and rate, and the split appears instantly.

Divide the gross total by (1 + rate ÷ 100). At 5%, a C$1,000.00 total divides to a C$952.38 net — the tax inside it is C$47.62. Choose “Remove tax” in the calculator and it does this for you.

No. Most GST systems zero-rate exports and exempt or reduce essentials such as food, medicine or education — but which items qualify differs by country, so check the local rules for your item. The calculator uses the standard rate; type a different rate if your item qualifies for another.
