Ontario Sales Tax Rates

Ontario has a complex sales tax system that includes multiple tax rates depending on the type of product you're purchasing. The main tax rates are:

Tax Type Rate Applies To
HST (Harmonized Sales Tax) 13% Most goods and services
PST (Provincial Sales Tax) 8% Certain goods and services
GST (Goods and Services Tax) 5% Federal tax on most goods and services

The total tax rate you'll pay depends on which taxes apply to your purchase. For example, a purchase subject to both HST and PST would have a total tax rate of 21%.

How Sales Tax Works in Ontario

Sales tax in Ontario is collected by retailers and remitted to the government. The tax is applied to the price of most goods and services sold in Ontario. Here's how it works:

  1. The retailer adds the sales tax to the price of the item.
  2. The customer pays the total amount, which includes the original price plus tax.
  3. The retailer then remits the tax portion to the government.

Sales Tax Formula

Total Cost = Item Price + (Item Price × Tax Rate)

Or

Total Cost = Item Price × (1 + Tax Rate)

This calculator uses the second formula to calculate the total cost including tax.

Worked Examples

Example 1: HST Only

If you purchase an item priced at $100 with a 13% HST rate:

Total Cost = $100 × (1 + 0.13) = $113

The total cost including tax would be $113.

Example 2: HST and PST

If you purchase an item priced at $100 with both HST (13%) and PST (8%):

Total Tax Rate = 13% + 8% = 21%

Total Cost = $100 × (1 + 0.21) = $121

The total cost including tax would be $121.
