Understanding Ontario's Sales Tax System

Ontario uses a Harmonized Sales Tax (HST) of 13%, which combines the federal Goods and Services Tax (GST) of 5% with Ontario's provincial component of 8% into a single, seamlessly collected tax. Ontario harmonized its provincial sales tax with the federal GST in 2010, replacing the old Ontario Retail Sales Tax (RST) system. This harmonization dramatically simplified compliance for businesses — instead of filing two separate returns for two different taxes, Ontario businesses now file a single HST return with the Canada Revenue Agency (CRA).

Ontario is Canada's most populous province and its largest economy, generating the highest volume of HST-related business activity in the country. From Toronto's massive financial services and tech sector to the manufacturing corridor of the Golden Horseshoe, businesses collect and remit enormous quantities of HST every quarter. For consumers, the 13% rate applies to most goods and services purchased in Ontario, making reverse HST calculation a routine necessity for expense tracking, accounting, and business financial management.

Why Reverse Tax Calculation Matters in Ontario

Ontario's HST has a broad base — it applies to most goods and services that Canadians purchase daily. Unlike some provinces with narrower tax bases, Ontario's harmonized system captures a wide range of transactions. This means accurate reverse calculation is important not just for businesses but for individual consumers trying to understand their spending or claim input tax credits (ITCs).

For businesses registered for HST, the ability to accurately identify the HST component of every purchase is essential for claiming ITCs on their HST returns. Input tax credits allow businesses to recover the HST they paid on business expenses, reducing their net HST liability. Accurate reverse calculation is the first step in identifying recoverable HST on every business purchase.

Real-World Reverse Calculation Example

You purchased office supplies in Toronto, Ontario for a total of $113.00 including 13% HST.

  • Convert HST rate: 13.00% ÷ 100 = 0.13
  • Add 1: 1 + 0.13 = 1.13
  • Divide: $113.00 ÷ 1.13 = $100.00 (pre-HST price)
  • HST amount: $113.00 − $100.00 = $13.00
  • GST component (5/13 of HST): $13.00 × 5/13 = $5.00
  • Provincial component (8/13 of HST): $13.00 × 8/13 = $8.00
  • ✓ Pre-tax price: $100.00 | Total HST: $13.00 (GST: $5.00 + Provincial: $8.00)

Ontario HST Compliance & Filing

Ontario HST is administered by the Canada Revenue Agency (CRA), not a provincial agency. Businesses with $30,000 or more in annual taxable supplies must register for a GST/HST account. Voluntary registration is available for smaller businesses, which allows them to claim ITCs. HST returns are filed monthly, quarterly, or annually depending on the business's annual taxable supplies. Returns and payments are due one month after the reporting period ends (annual filers have three months). Ontario businesses can use the CRA's My Business Account portal for online filing.

Frequently Asked Questions — Ontario HST

Ontario uses HST (Harmonized Sales Tax) at 13%, which is a single combined tax replacing the separate federal GST (5%) and Ontario's old provincial sales tax. You pay one combined 13% tax on most purchases — there is no separate provincial tax line item in Ontario.
Basic groceries (most food for human consumption) are zero-rated, meaning no HST applies. However, certain food items are taxable — including carbonated drinks, chips, candy, and food sold at restaurants. The distinction between zero-rated and taxable food can be nuanced.
Yes. HST-registered businesses can claim Input Tax Credits (ITCs) to recover the HST paid on business expenses. For example, if your business paid $113.00 including $13.00 HST for office supplies, you can claim back the $13.00 HST through your HST return.
Ontario harmonized its provincial sales tax with the federal GST on July 1, 2010. Before harmonization, Ontario had a separate Retail Sales Tax (RST) of 8% that was administered separately from the federal GST.
Businesses with $30,000 or more in annual taxable supplies must register for GST/HST. Smaller businesses below this threshold are not required to register, but can do so voluntarily to claim ITCs on their business expenses.
