How to Calculate Hst on Gas in Ontario

When you purchase gasoline in Ontario, the Harmonized Sales Tax (HST) is automatically added to the price. Understanding how to calculate HST on gas purchases can help you budget effectively and verify your receipts. This guide explains the HST calculation process, provides an interactive calculator, and answers common questions about HST on gasoline.

What is HST?

The Harmonized Sales Tax (HST) is a combined sales tax and goods and services tax that applies to most goods and services sold in Ontario. It replaced the previous system of provincial sales tax and federal goods and services tax in 2010. The HST rate in Ontario is currently 13%.

When you buy gasoline, the HST is included in the total price you pay. This means the price you see at the pump already includes the HST amount. However, understanding how to calculate the HST separately can be helpful for budgeting and verifying your expenses.

How to Calculate HST on Gas

Calculating the HST on gasoline purchases is straightforward once you know the HST rate and the pre-tax price of the gas. Here's the step-by-step process:

Determine the pre-tax price of the gasoline. This is the price before HST is added.
Multiply the pre-tax price by the HST rate (13% or 0.13).
The result is the amount of HST paid on the gasoline purchase.

HST Calculation Formula

HST Amount = Pre-Tax Price × HST Rate

Total Price = Pre-Tax Price + HST Amount

For example, if gasoline costs $1.50 per liter before tax, the HST would be $0.195 (1.50 × 0.13), making the total price $1.695 per liter.

Example Calculation

Let's walk through a practical example to illustrate how to calculate HST on gasoline purchases in Ontario.

Scenario

You fill up your car with 40 liters of regular unleaded gasoline at a price of $1.50 per liter before tax.

Step 1: Calculate the Pre-Tax Total

First, calculate the total cost before tax:

Pre-Tax Total = Price per Liter × Number of Liters

Pre-Tax Total = $1.50 × 40 = $60.00

Step 2: Calculate the HST Amount

Next, calculate the HST amount using the formula:

HST Amount = Pre-Tax Total × HST Rate

HST Amount = $60.00 × 0.13 = $7.80

Step 3: Calculate the Total Price

Finally, add the HST amount to the pre-tax total to get the total price:

Total Price = Pre-Tax Total + HST Amount

Total Price = $60.00 + $7.80 = $67.80

Note: The price you see at the pump already includes the HST, so you don't need to add it manually. This example shows how the calculation works behind the scenes.
