GST vs HST Difference in Canada What Businesses and Consumers Need to Know
Canada uses several types of sales taxes, and understanding them can prevent costly mistakes when shopping or running a business. The gst vs hst difference mainly comes down to how federal and provincial taxes are collected and combined.
Some provinces apply only the federal tax, others combine federal and provincial taxes into one system, and a few maintain separate provincial taxes. Knowing where each system applies makes sales tax much easier to understand.
Understanding Canada’s Sales Tax System
Canada’s sales tax framework includes federal and provincial components. These taxes fund public services such as healthcare, infrastructure, and education. The system is administered primarily by the Canada Revenue Agency.
Before comparing the taxes directly, it helps to understand how each one works individually.
What Is GST (Goods and Services Tax)?
GST stands for Goods and Services Tax. It is a federal value-added tax introduced in 1991 and applies to most goods and services sold in Canada.
The current GST rate is 5%. According to the Canada Revenue Agency, businesses must charge GST when they exceed the small supplier threshold of $30,000 in annual taxable revenue.
GST applies nationwide, but the final tax rate depends on whether a province adds additional taxes.
What Is HST (Harmonized Sales Tax)?
HST, or Harmonized Sales Tax, combines the federal GST and provincial sales tax into a single unified rate. Instead of charging two separate taxes, businesses apply one harmonized rate.
The federal government still administers HST through the Canada Revenue Agency, which simplifies tax collection for businesses operating in those provinces.
Depending on the province, the HST rate ranges between 13% and 15%.
In short, HST is essentially GST plus provincial sales tax merged into one system.
GST vs HST Difference Explained Clearly
The main gst vs hst difference lies in how the taxes are structured and collected. GST is strictly federal, while HST includes both federal and provincial portions in one rate.
The following table explains the key distinctions.
Key comparison between GST and HST in Canada
| Feature | GST | HST |
|---|---|---|
| Tax type | Federal sales tax | Combined federal and provincial tax |
| Rate | 5% | 13%–15% |
| Administration | Canada Revenue Agency | Canada Revenue Agency |
| Where used | All provinces | Only selected provinces |
This structure means consumers often pay a higher single rate in HST provinces but deal with a simpler system overall.
For businesses selling across provinces, understanding the correct rate based on location is essential.
Provinces That Use GST, HST, or PST in Canada
Canada does not apply one uniform tax nationwide. Instead, provinces choose different systems based on their fiscal policies.
The following table shows how sales tax works across the country.
Canadian provinces and their sales tax systems
| Province or Territory | Tax System | Total Rate |
|---|---|---|
| Ontario | HST | 13% |
| Nova Scotia | HST | 15% |
| New Brunswick | HST | 15% |
| Newfoundland and Labrador | HST | 15% |
| Prince Edward Island | HST | 15% |
| Alberta | GST only | 5% |
| British Columbia | GST + PST | 12% |
If you want a detailed breakdown of tax rates across Canada, you can review the Canadian HST provinces list, which explains how each province applies sales tax.
Different tax systems exist largely due to provincial economic decisions and voter preferences.
British Columbia, for example, briefly adopted HST but returned to the GST + PST system after a public referendum in 2013, according to data from the Department of Finance Canada.
GST vs HST Calculation Examples
Understanding the numbers behind the gst vs hst difference becomes easier with simple examples.
Example 1: Buying a Laptop in Ontario
If a laptop costs $1,000 in Ontario, the HST rate is 13%. The final price becomes $1,130 after tax.
This single rate already includes both federal and provincial tax portions.
Example 2: Buying the Same Laptop in Alberta
In Alberta, only GST applies. The same $1,000 laptop would cost $1,050 after adding the 5% federal tax.
Consumers often notice this difference when travelling between provinces.
Small price changes can quickly add up.
A $500 purchase in Ontario adds $65 tax under HST, while the same purchase in Alberta adds only $25 in GST. Over a year of spending, that difference can be significant.

GST vs HST Difference for Businesses
Businesses often need a deeper understanding of the gst vs hst difference because they are responsible for collecting and remitting sales tax.
Incorrect tax collection can lead to penalties or repayment obligations.
When Businesses Must Register for GST/HST
A business must register for GST/HST once its taxable revenue exceeds $30,000 within 12 months. This threshold is called the small supplier limit.
After registration, businesses charge the appropriate tax based on the customer’s location.
Input Tax Credits Explained
Registered businesses can claim Input Tax Credits (ITCs) to recover tax paid on business expenses.
For example, if a company buys equipment and pays $500 in HST, it can claim that amount when filing its tax return.
Charging the Correct Tax by Province
Businesses selling online must apply the correct tax depending on where the customer lives. This rule is called the place-of-supply rule.
Many accountants recommend using specialized resources such as the tax toolkit to track provincial rules and calculate accurate rates when dealing with multiple provinces.
Common Confusion: GST vs HST vs PST
People sometimes assume HST is an entirely separate tax. In reality, it simply merges two taxes into one combined rate.
Understanding the relationship between these taxes helps clarify Canada’s sales tax structure.
What Is PST?
PST stands for Provincial Sales Tax. It is charged separately in some provinces, including British Columbia, Saskatchewan, and Manitoba.
Unlike HST, PST is administered by the provincial government rather than the Canada Revenue Agency.
GST vs HST vs PST Comparison
The table below shows how these three taxes differ.
Comparison of major Canadian sales taxes
| Tax Type | Who Collects It | Where It Applies |
|---|---|---|
| GST | Federal government | All provinces |
| HST | Federal government (combined tax) | Selected provinces |
| PST | Provincial government | Specific provinces |

FAQS For GST vs HST Difference
What is the main GST vs HST difference in Canada?
The main difference is how the tax is structured. GST is a 5% federal sales tax applied across Canada, while HST combines the federal GST with provincial sales tax into one single rate. In HST provinces, businesses charge one harmonized rate instead of separate taxes.
Which provinces use HST in Canada?
Five provinces currently use Harmonized Sales Tax: Ontario, Nova Scotia, New Brunswick, Newfoundland and Labrador, and Prince Edward Island. In these regions, the provincial tax and federal GST are merged into a single rate ranging from 13% to 15%.
Is HST the same as GST plus PST?
Not exactly. HST combines GST and the provincial tax into one unified system administered by the Canada Revenue Agency. In provinces with PST, the provincial tax is collected separately from the federal GST.
Why does Alberta only charge GST?
Alberta does not have a provincial sales tax, so only the 5% federal GST applies to most purchases. This means consumers in Alberta typically pay less sales tax compared to provinces that use HST or PST systems.
Do small businesses charge GST or HST?
Small businesses must charge GST or HST once their taxable revenue exceeds $30,000 within a 12-month period. The exact tax they charge depends on the customer’s province and the place-of-supply rules set by the Canada Revenue Agency.
How do businesses know whether to charge GST or HST?
Businesses determine the correct tax based on the customer’s location. If the buyer is located in an HST province, the harmonized rate applies; otherwise GST or GST plus PST may be required. These rules are known as place-of-supply rules.
What is the current GST rate in Canada?
The current GST rate is 5% nationwide. It has remained at this level since 2008, when the federal government reduced the rate from 7% to support consumer spending and economic growth.
Quick Summary
The gst vs hst difference mainly comes down to how taxes are structured. GST is a 5% federal tax applied nationwide, while HST combines federal and provincial taxes into one rate between 13% and 15%.
Some provinces use HST to simplify tax collection, while others keep separate provincial taxes alongside GST. For businesses, the most important rule is charging the correct tax based on the customer’s province.
Once you understand how the system works, calculating Canadian sales tax becomes much easier for both consumers and business owners.
