How Much Is HST in Ontario?

The Harmonized Sales Tax (HST) in Ontario is 13%. This combined rate was introduced on July 1, 2010, replacing the separate federal Goods and Services Tax (GST) and provincial Retail Sales Tax (PST). The 13% rate is composed of a 5% federal portion and an 8% provincial portion. Both components are reported and remitted together directly to the Canada Revenue Agency (CRA).

To calculate Ontario HST manually, you can multiply the pre-tax price by 0.13. For a reverse calculation to extract the tax from a total, divide the gross total by 1.13.
