Ontario HST Calculator: Calculate Harmonized Sales Tax Free

Our Ontario HST calculator is a free online tool that helps you calculate the 13% Harmonized Sales Tax on any purchase in Ontario, Canada. Whether you need to add HST to a pre-tax price or remove HST from a tax-inclusive amount, this calculator provides instant results with a complete breakdown of the GST and PST components.

Ontario combined its 8% Provincial Sales Tax (PST) with the 5% federal Goods and Services Tax (GST) on July 1, 2010, creating the single 13% Harmonized Sales Tax (HST). This unified tax simplified the tax system for businesses and consumers by replacing two separate taxes with one. Understanding how HST works is essential for budgeting, invoicing, and financial planning in Ontario.

What is Ontario HST?

HST stands for Harmonized Sales Tax, which is a value-added tax that combines federal and provincial sales taxes into a single rate. In Ontario, the HST rate is 13%, broken down as 5% federal GST plus 8% provincial tax. The HST applies to most goods and services purchased in Ontario, with some exceptions for essential items like basic groceries, prescription medications, and medical devices.

The HST system replaced the previous two-tax system where consumers and businesses had to calculate and remit both GST and PST separately. Under the HST system, a single tax rate applies and is collected by the Canada Revenue Agency (CRA), which then distributes the provincial portion to the Ontario government. This streamlined approach reduced administrative burden for businesses operating across provinces.

Ontario HST Calculation Formulas

The formulas for calculating Ontario HST are straightforward:

Adding HST to a Pre-Tax Price

HST Amount = Pre-Tax Price x 0.13
Total Price = Pre-Tax Price + HST Amount

Example: A product costs $200 before tax
HST = 200 x 0.13 = $26.00
Total = 200 + 26 = $226.00
GST portion = 200 x 0.05 = $10.00
PST portion = 200 x 0.08 = $16.00

Removing HST from a Tax-Inclusive Price

Pre-Tax Price = Total Price / 1.13
HST Amount = Total Price - Pre-Tax Price

Example: You paid $226 including HST
Pre-Tax = 226 / 1.13 = $200.00
HST = 226 - 200 = $26.00
GST = 200 x 0.05 = $10.00
PST = 200 x 0.08 = $16.00

Ontario HST: What You Need to Know

Ontario's 13% HST applies to a wide range of goods and services. Most consumer purchases, restaurant meals, clothing over $30, electronics, furniture, and professional services are subject to the full 13% HST. The tax is collected at the point of sale and remitted to the CRA by the vendor.

How do I calculate 13% HST on a price?
