What is HST? (Harmonized Sales Tax)
The Harmonized Sales Tax (HST) is a consumption tax in Canada that combines the federal Goods and Services Tax (GST) with a provincial sales tax (PST) into a single, harmonized tax. Introduced to streamline the sales tax system, HST is collected by the federal government and a portion is remitted to participating provinces. This means that in HST-implementing provinces, you pay one single tax rate on most goods and services, rather than separate GST and PST charges.
This Canadian tax calculator is designed for anyone needing to quickly determine the HST, GST, or PST components of a price. It's particularly useful for consumers making purchases, businesses invoicing clients, or anyone budgeting for expenses in Canada. Understanding the HST is crucial for financial planning, whether you're buying a new car, paying for services, or managing business expenses.
A common misunderstanding about HST is confusing it with GST or PST. While GST is a federal tax applied across Canada (currently 5%), and PST is a provincial tax applied in non-harmonized provinces, HST is a combined tax. For example, in Ontario, the 13% HST includes both the 5% federal portion and an 8% provincial portion. Our HST calculator clarifies these distinctions by providing the specific rate for your chosen province.
HST Formula and Explanation
Calculating HST involves straightforward arithmetic, but the formula varies slightly depending on whether you're adding HST to a subtotal or extracting it from a total price that already includes tax. This sales tax Canada tool simplifies both scenarios.
1. Calculating HST when the price is *before* tax (Subtotal given):
- HST Amount = Subtotal × HST Rate
- Total Price = Subtotal + HST Amount
Or, more simply:
- Total Price = Subtotal × (1 + HST Rate)
2. Calculating HST when the price *includes* tax (Total Price given):
- Subtotal = Total Price / (1 + HST Rate)
- HST Amount = Total Price - Subtotal
The "HST Rate" is expressed as a decimal in these formulas (e.g., 13% becomes 0.13). Our HST calculator handles this conversion automatically for your convenience.
Variables Used in HST Calculation:
| Variable | Meaning | Unit | Typical Range |
|---|---|---|---|
| Subtotal | The price of goods or services before any tax is applied. | Canadian Dollars (CAD) | Any positive value |
| HST Rate | The combined federal and provincial sales tax rate. | Percentage (%) | 5% to 15% (varies by province) |
| HST Amount | The monetary value of the Harmonized Sales Tax. | Canadian Dollars (CAD) | Any positive value |
| Total Price | The final price including all applicable taxes. | Canadian Dollars (CAD) | Any positive value |
Practical Examples
Example 1: Adding HST to a Subtotal
Scenario: Buying a product in Ontario
You find a gadget with a listed price of $250.00 before tax. You are in Ontario, where the HST rate is 13%.
- Inputs:
- Original Price / Subtotal: $250.00
- Select Province: Ontario (13% HST)
- Price entered already includes HST: Unchecked
- Calculation:
- HST Amount = $250.00 × 0.13 = $32.50
- Total Price = $250.00 + $32.50 = $282.50
- Results:
- Total Price (incl. tax): $282.50
- Subtotal (before tax): $250.00
- HST Amount: $32.50
- Tax Rate Applied: 13.00%
Example 2: Extracting HST from an Inclusive Price
Scenario: Understanding a receipt in New Brunswick
You paid $115.00 for a meal, and the receipt states this price already includes tax. You're in New Brunswick, where the HST rate is 15%.
- Inputs:
- Original Price / Subtotal: $115.00
- Select Province: New Brunswick (15% HST)
- Price entered already includes HST: Checked
- Calculation:
- Subtotal = $115.00 / (1 + 0.15) = $115.00 / 1.15 = $100.00
- HST Amount = $115.00 - $100.00 = $15.00
- Results:
- Total Price (incl. tax): $115.00
- Subtotal (before tax): $100.00
- HST Amount: $15.00
- Tax Rate Applied: 15.00%
How to Use This HST Calculator
Our HST calculator is designed for ease of use, providing accurate results in seconds. Follow these simple steps:

Key Factors That Affect HST
The Harmonized Sales Tax, and Canadian sales taxes in general, are influenced by several factors. Being aware of these can help you better understand your financial obligations and entitlements.
- Provincial Rates: This is the most significant factor. HST rates (and combined GST/PST rates) are set by each province/territory. For instance, Ontario has 13% HST, while Alberta only has 5% GST. Our PST rates Canada guide provides more detail.
- Type of Good or Service: Not all goods and services are subject to HST. Certain items are "zero-rated" (0% tax, but businesses can claim input tax credits) like basic groceries, prescription drugs, and some medical devices. Others are "exempt" (no tax, and businesses cannot claim input tax credits) such as financial services, most residential rents, and some educational services.
- Point of Sale: The tax rate applied is generally based on where the good or service is supplied or delivered, not necessarily where the buyer resides. This is particularly relevant for online purchases.
- Supplier's Registration Status: Businesses that are "small suppliers" (annual taxable sales below a certain threshold, typically $30,000) are generally not required to register for or collect HST. However, they cannot claim input tax credits.
- Rebates and Exemptions: Certain individuals or organizations may be eligible for HST rebates (e.g., new housing rebates, public service bodies' rebates). Some specific purchases or situations might also qualify for exemptions.
- Changes in Legislation: Tax rates and rules can change. Governments periodically review and adjust their tax policies, which can impact the HST. It's always wise to use up-to-date tools like this HST calculator and consult official government resources for the latest information.
Frequently Asked Questions about HST
What is the Harmonized Sales Tax (HST)?
The HST is a consumption tax in Canada that combines the federal Goods and Services Tax (GST) with a provincial sales tax (PST) into a single tax. It simplifies tax collection for businesses and consumers in participating provinces.
Which Canadian provinces use HST?
As of current rates, provinces that have harmonized their sales tax with the federal GST are New Brunswick (NB), Newfoundland and Labrador (NL), Nova Scotia (NS), Ontario (ON), and Prince Edward Island (PE). Other provinces have separate GST and PST, or only GST.
What's the difference between GST, PST, and HST?
GST (Goods and Services Tax): A 5% federal tax applied across all of Canada.
PST (Provincial Sales Tax): A provincial tax applied in non-HST provinces (e.g., BC, MB, SK, QC). It's added on top of the GST (except in Quebec where QST is applied to the price including GST).
HST (Harmonized Sales Tax): A combined federal and provincial sales tax applied in HST-participating provinces. It's a single percentage rate that includes both the 5% federal portion and the provincial portion.
Are all goods and services subject to HST?
No. While most goods and services are subject to HST, some are "zero-rated" (taxable at 0%, like basic groceries and prescription drugs) and others are "exempt" (not subject to tax, like financial services, certain health services, and most residential rents). Our HST calculator applies to standard taxable items.
Can I get an HST rebate?
Yes, in certain situations. For instance, individuals may qualify for a new housing rebate on a newly built or substantially renovated home. Businesses can claim "Input Tax Credits" (ITCs) for the HST paid on purchases related to their commercial activities. Public service bodies also have specific rebate programs. Consult the Canada Revenue Agency (CRA) for details.
How does the "Price includes HST" option work in the calculator?
If you check this box, the calculator assumes the "Original Price" you entered is the final amount paid (including tax). It will then work backward to determine the subtotal before tax and the exact tax amount included in that total. If unchecked, it assumes the "Original Price" is the subtotal, and it will add the tax to calculate the total.
How often do HST rates change?
HST rates are determined by provincial governments (for their provincial portion) and the federal government (for GST). While not frequent, rates can change. Our calculator uses the most up-to-date information available, but it's always good practice to verify with official government sources for critical financial decisions.
Is this HST calculator accurate for all situations?
This calculator provides accurate calculations for standard HST, GST, and PST scenarios on taxable goods and services based on the selected province. However, it does not account for specific exemptions, zero-rated items, complex business input tax credits, or specific provincial rebates. For highly specialized situations or tax advice, always consult a qualified tax professional or the Canada Revenue Agency.
