Ontario HST: 13% Tax Explained
Ontario's Harmonized Sales Tax (HST) combines the 5% federal GST and 8% provincial PST into a single 13% tax. It has applied to most goods and services since July 1, 2010.
When to Charge Ontario HST
You must register for HST if your business revenue exceeds $30,000 over four consecutive calendar quarters. Below this threshold, registration is voluntary. See our CRA invoice requirements guide for compliance details.
HST-Exempt Items in Ontario
Some items are HST-exempt in Ontario, including basic groceries, prescription drugs, medical devices, and most health and dental services. Use our invoice generator to create tax-exempt invoices.
HST on Invoices
CRA requires you to show the HST amount separately on invoices over $30. For invoices over $150, you must also include your GST/HST registration number and business name. Learn more about how to calculate GST/HST on invoices.
Common Prices Plus 13% Ontario HST
The 13% HST rate applies uniformly across all of Ontario, including Toronto, Ottawa, Hamilton, London, and Mississauga.
