How to calculate HST in Ontario
The HST in Ontario is 13%: the 5% federal GST plus the 8% Ontario provincial portion, combined into one tax. To add it, multiply the price before tax by 1.13.
| Price before tax | HST (13%) | Total with HST |
|---|---|---|
| $10.00 | $1.30 | $11.30 |
| $50.00 | $6.50 | $56.50 |
| $100.00 | $13.00 | $113.00 |
| $1,000.00 | $130.00 | $1,130.00 |
The 13% rate has applied in Ontario since July 1, 2010, when the HST replaced the separate GST and provincial retail sales tax. It is the same in Toronto, Ottawa, Mississauga, Hamilton and every other city in the province.
Reverse HST calculator: find the price before tax
To remove the HST from a total, divide the total by 1.13. Do not subtract 13% from the total: that gives the wrong answer.
Example
A receipt shows $56.50 with tax. $56.50 ÷ 1.13 = $50.00 before tax, so the HST paid is $6.50.
The common mistake
Subtracting 13% from $56.50 gives $49.16, which is $0.84 too low. The 13% applies to the price before tax, not to the total.
In the calculator
Type the total in the Total with HST box: the price before tax and the HST appear instantly. Go to the calculator
