Read full articleOntario's HST rate is 13%, consisting of 5% federal GST and 8% provincial PST. This is a single blended tax administered by the Canada Revenue Agency.
Multiply the pre-tax amount by 13% (0.13). For example, $100 × 0.13 = $13 HST, making the total $113.
Divide the total by 1.13 to get the pre-tax amount. For example, $113 ÷ 1.13 = $100 pre-tax, and $113 - $100 = $13 HST.
