Ontario charges 13% in total sales tax. Enter any amount below to add or remove it.
Ontario harmonised its 8% provincial tax with the 5% federal GST in July 2010, so a single 13% HST is charged rather than two separate lines.
Direct answer
Ontario general sales tax is 13%, collected as a single 13% HST. On a $100.00 taxable purchase, tax is $13.00 and the total is $113.00. To remove tax from a total in Ontario, divide by 1.13.

| Component | Rate | Tax on $100 |
|---|---|---|
| HST (harmonised federal + provincial) | 13% | $13.00 |
| Total | 13% | $13.00 |
| Before tax | Tax at 13% | Total |
|---|---|---|
| $10.00 | $1.30 | $11.30 |
| $50.00 | $6.50 | $56.50 |
| $100.00 | $13.00 | $113.00 |
| $500.00 | $65.00 | $565.00 |
| $1,000.00 | $130.00 | $1,130.00 |
| $5,000.00 | $650.00 | $5,650.00 |
If the price already includes tax, divide by 1.13. That gives the before-tax price; the tax amount is the original total minus the before-tax price.
| Tax-included total | Before tax | Tax removed |
|---|---|---|
| $56.50 | $50.00 | $6.50 |
| $113.00 | $100.00 | $13.00 |
| $565.00 | $500.00 | $65.00 |
| $1,130.00 | $1,000.00 | $130.00 |
Ontario has the 8th-lowest combined sales tax rate in Canada, at 13%. Rates run from 5% in Alberta to 15% in Newfoundland.
total = before-tax price x 1.13
before-tax price = tax-included total / 1.13
tax = total - before-tax price

Ontario charges 13% in total sales tax, collected as a single 13% HST.
Multiply the pre-tax price by 1.13. For example, $100 becomes $113.00.
Divide the total by 1.13. A $113.00 total works back to $100.00 before tax. The calculator's Remove Tax mode does this for you.
