How to Calculate Tax on An Item in Ontario

Calculating tax on an item in Ontario is essential for understanding the total cost of goods and services. This guide explains how to calculate Ontario's Harmonized Sales Tax (HST) or Goods and Services Tax (GST) and provides an interactive calculator to make the process simple.

How Tax Works in Ontario

Ontario uses a value-added tax system called the Harmonized Sales Tax (HST). The HST combines the federal Goods and Services Tax (GST) and the provincial Sales Tax (PST) into a single tax rate. This means when you purchase an item in Ontario, the HST is added to the price.

The HST is applied to most goods and services sold in Ontario. Some exceptions include basic food items, prescription drugs, and medical services. The tax is collected by retailers and remitted to the government, with the proceeds used for various public services.

Ontario Tax Rates

The current HST rate in Ontario is 13%. This rate combines the federal GST of 5% and the provincial PST of 8%. The HST rate is applied to the pre-tax price of an item.

Note: The HST rate may change periodically. Always verify the current rate before calculating tax.

Calculation Method

To calculate the tax on an item in Ontario, follow these steps:

Determine the pre-tax price of the item.
Multiply the pre-tax price by the HST rate (13%).
Add the calculated tax to the pre-tax price to get the total cost.

Formula:

Tax Amount = Pre-Tax Price × HST Rate (13%)

Total Cost = Pre-Tax Price + Tax Amount

For example, if an item costs $100 before tax, the tax amount would be $13, and the total cost would be $113.

Worked Examples

Example 1: Calculating Tax on a $50 Item

Pre-tax price: $50

Tax amount: $50 × 13% = $6.50

Total cost: $50 + $6.50 = $56.50

Example 2: Calculating Tax on a $200 Item

Pre-tax price: $200

Tax amount: $200 × 13% = $26

Total cost: $200 + $26 = $226
