How Do I Calculate Hst in Ontario

Calculating HST (Harmonized Sales Tax) in Ontario is essential for businesses and consumers. This guide explains the HST calculation process, current rates, exemptions, and how to apply HST correctly.

What is HST in Ontario?

HST stands for Harmonized Sales Tax. It's a single sales tax that replaces the previous system of provincial sales tax (PST) and goods and services tax (GST). In Ontario, HST is collected by retailers and remitted to the government.

The HST system was introduced in 2010 to simplify the sales tax collection process. It combines the GST and PST into one tax rate, making it easier for businesses and consumers to understand their tax obligations.

How to Calculate HST in Ontario

Calculating HST in Ontario involves determining the taxable amount and applying the current HST rate. Here's the basic formula:

HST Amount = (Taxable Amount × HST Rate) / 100

Total Amount = Taxable Amount + HST Amount

For example, if you purchase an item with a taxable amount of $100 at the standard HST rate of 13%, the calculation would be:

HST Amount = ($100 × 13) / 100 = $13

Total Amount = $100 + $13 = $113

This means the total cost including HST would be $113.
