Ontario'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.
GST is the federal Goods and Services Tax (5%). PST is the provincial portion (8% in Ontario). Together they form the 13% HST, collected as one combined tax.
Basic groceries, child care, prescription drugs, medical devices, educational services, and residential rent are generally exempt from HST.
Most goods and services are subject to HST, but some are zero-rated (taxable at 0%) like basic groceries, or exempt like health and educational services.
Yes, registered businesses can claim ITCs to recover HST paid on business expenses. This means the business effectively pays HST only on the value they add.
No. Some provinces use HST (Ontario 13%, Quebec 14.975%, etc.), others use separate GST + PST, and Alberta has only 5% GST with no provincial sales tax.
