If you’ve ever wondered how consumption taxes work across Canada, understanding the Harmonized Sales Tax (HST) is vital. Implemented in select provinces, HST simplifies tax collection by combining federal and provincial sales taxes into one system. But which provinces use it, and how is it applied? Let’s break it down clearly and simply for you.
Whether you’re unsure about how much HST you’re paying or you’re running a business that spans multiple provinces, knowing which areas use HST and their respective rates will help you stay informed. Let’s dive into the details to better understand this system.
What Is HST and How Does It Work?
The Harmonized Sales Tax (HST) is a unified consumption tax used in certain provinces in Canada. HST combines the Goods and Services Tax (GST), which is federally imposed, and the Provincial Sales Tax (PST), into a single value-added tax. This structure is designed to streamline tax collection and compliance, particularly for businesses operating within HST provinces.
Under this system, the total HST includes a fixed federal portion of 5%, with the remaining percentage varying depending on the province’s PST. The tax is collected at every stage of the supply chain, but businesses registered for HST can claim input tax credits to avoid being taxed multiple times for the same goods or services.
Which Provinces Use the HST?
As of 2025, five Canadian provinces have adopted HST. Each province determines the provincial portion of the tax, contributing to the total combined rate. Below is a detailed breakdown of the current HST rates:
| Province | HST Rate | Federal Portion (GST) | Provincial Portion | Rate Effective Date |
|---|---|---|---|---|
| New Brunswick | 15% | 5% | 10% | July 1, 2016 |
| Newfoundland and Labrador | 15% | 5% | 10% | July 1, 2016 |
| Nova Scotia | 14% | 5% | 9% | April 1, 2025 |
| Ontario | 13% | 5% | 8% | July 1, 2010 |
| Prince Edward Island | 15% | 5% | 10% | April 1, 2013 |
Provinces Without HST
Not all provinces have adopted the HST system. Here’s what the tax landscape looks like in those regions:
- Alberta, Northwest Territories, Nunavut, and Yukon: Charge only the 5% GST.
- British Columbia (BC): 5% GST + 7% PST = 12% total.
- Manitoba: 5% GST + 7% PST = 12% total.
- Saskatchewan: 5% GST + 6% PST = 11% total.
- Quebec: 5% GST + 9.975% PST = 14.975% total.
While these provinces use separate GST and PST systems, Quebec is unique in that it administers its tax independently through Revenu Québec.
Why HST Matters
Understanding HST is crucial for businesses and consumers alike. For businesses, it simplifies tax compliance, particularly for those operating in multiple provinces.
Consumers may also benefit from a single tax that’s applied transparently at checkout. Knowing your region’s tax rate is key when planning purchases.
