Key Points About HST on Gasoline

The HST is applied to the total price of gasoline, not just the fuel itself.
Some provinces in Canada have different tax structures, but Ontario uses the HST system.
Gasoline is considered a taxable good, so the HST applies to all purchases.

Calculation Method

To calculate the HST on gasoline in Ontario, you need to know the total price of the gasoline including the HST. The formula to find the HST amount is:

HST Amount = (Total Price × HST Rate) / (1 + HST Rate)

Where:

Total Price is the price you pay for the gasoline, including HST.
HST Rate is 13% (or 0.13 in decimal form).

Alternatively, you can calculate the base price of the gasoline before tax using:

Base Price = Total Price / (1 + HST Rate)

This formula helps you separate the tax amount from the actual cost of the gasoline.

Example Calculation

Let's say you buy gasoline that costs $120.00 including HST. Here's how to calculate the HST amount and the base price:

HST Amount = ($120.00 × 0.13) / (1 + 0.13) = $12.00

Base Price = $120.00 / 1.13 ≈ $106.19

In this example, the HST amount is $12.00, and the base price of the gasoline is approximately $106.19.
