Breakdown

GST formulas and examples

Use these formulas to check the amount added to a tax-free price or removed from a tax-included total.

Add tax

Total = tax-free price x (1 + rate / 100)

Remove tax

Tax-free price = tax-included total / (1 + rate / 100)

Tax amount

Tax = tax-free price x rate / 100

Quick example

Starting from $100, a 5% rate gives $5 in tax and $105 total.

Starting from $105, the tax-free amount is $100 and the tax is $5.

Official checks

Canada GST and HST depend on the place of supply

Canada uses the Goods and Services Tax (GST) and, in participating provinces, the Harmonized Sales Tax (HST). The federal GST rate has been 5% since 1 January 2008.

Current HST totals are 13% in Ontario, 14% in Nova Scotia from 1 April 2025, and 15% in New Brunswick, Newfoundland and Labrador, and Prince Edward Island. Zero-rated supplies, such as basic groceries, use 0% across Canada. Other provinces may impose a separate PST or QST.

Canadian dollar example and why the province matters

On CA$100 before tax, federal GST alone is CA$5 and the total is CA$105. The same taxable supply would total CA$113 at 13% HST, CA$114 at 14% HST or CA$115 at 15% HST.

This page's calculator is configured for the 5% federal GST only. It does not determine place of supply or automatically add HST, PST, QST, First Nations taxes, rebates or exemptions. Its result is orientative, not personalised tax advice.
