How the Ontario Sales Tax Calculator Works

This calculator estimates the sales tax breakdown for purchases in Ontario. Enter a before-tax amount (default) or switch to tax-included to reverse-calculate the subtotal.

  • Standard calculation: Enter your before-tax amount. Whether you are shopping in Toronto or Ottawa, the calculator automatically applies the 13% HST to show your final cost.
  • Reverse calculation (tax included): Turn on “Amount includes tax?”. Enter the total you paid, and the calculator works backward to separate the 13% HST from the original pre-tax sticker price.

Understanding HST in Ontario

While the general rate is 13%, Ontario applies a specific point-of-sale rebate on prepared food and beverages sold for $4.00 or less. In these cases, only the 5% GST is charged. This is widely known as the 'Muffin Rule'.

Retail prices displayed in Ontario stores do not include the 13% HST. You must always account for this extra charge at the checkout counter. If you need to figure out the tax portion of a paid invoice, simply use our 'Amount includes tax?' toggle.

How to calculate sales tax in Ontario (before tax and tax included)

The exact calculation formula in Ontario is: Total = Amount × 1.13. To reverse this and find the pre-tax amount from a final receipt, just divide the total by 1.13.

Total including tax = Before-tax amount × (1 + 13%)
Before-tax amount = Total including tax ÷ (1 + 13%)

Rules & Exemptions

  • Children’s clothing, footwear, diapers, and printed books are taxed at only 5%.
  • Rebates for new housing are available but subject to specific price caps.

FAQ - Ontario 2026

Why did my coffee only have 5% tax?

Because your total was likely under $4.00. Prepared food and drink under this threshold are exempt from the 8% provincial tax.

Are children's clothes tax-free?

Not entirely. They are exempt from the provincial portion (8%), so you still pay the 5% federal tax.

Is gas taxed in Ontario?

Yes, gasoline is subject to the 13% HST, calculated on top of the federal and provincial fuel excise taxes.
