About the Ontario HST

Understanding the HST in Ontario is essential for both consumers and business owners. The current combined rate is 13.000%, which is calculated on most goods and services purchased within the province. Keeping track of this rate ensures you aren't overcharged and allows businesses to remit the correct amount to the Canada Revenue Agency (CRA) or provincial tax authorities.

How the Ontario Tax Works

Depending on whether Ontario uses an HST, GST, or a split GST/PST system, the way tax is applied can vary slightly. For Ontario, the primary tax type is HST. This calculator instantly applies the exact 13.000% rate to any pre-tax amount. Conversely, if you only have a final receipt, the reverse calculation feature allows you to extract the exact tax paid and find the original base price. This is incredibly useful for expense reporting and claiming input tax credits.

Exemptions and Zero-Rated Goods

It's important to note that not all items are subject to the full 13.000% rate. Basic groceries, prescription drugs, and certain agricultural products are typically zero-rated. Additionally, some specific services might be entirely exempt. Always consult official provincial guidelines or a certified accountant for complex purchases or business operations in Ontario.
