Sales Tax Formula

The formula to calculate the total price including sales tax in Ontario is:

Formula

Total Price = Pre-Tax Price × (1 + HST Rate)

Where HST Rate = 13% (0.13)

For example, if an item costs $100 before tax, the total price including tax would be:

Example Calculation

Total Price = $100 × (1 + 0.13) = $113

Worked Examples

Example 1: Calculating Tax for a $50 Item

Pre-tax price: $50
Tax amount: $50 × 0.13 = $6.50
Total price: $50 + $6.50 = $56.50

Example 2: Calculating Tax for a $200 Item

Pre-tax price: $200
Tax amount: $200 × 0.13 = $26
Total price: $200 + $26 = $226

Rounding Rules

In Ontario, sales tax is typically rounded to the nearest cent. If the tax amount is less than $0.005, it is rounded down. If it is $0.005 or more, it is rounded up.
