Canada Sales Tax: What Every Business Needs to Know
Every business owner needs to know how to manage sales tax in Canada. There are different provincial sales taxes based on the types of products/services they sell in Canada. There are some provinces with combined rates, meaning all sales tax is charged at one rate, and there are also multiple provinces with different rates depending on the province where the sale is made.
If you don’t charge your customers the right amount of sales tax or don’t have an account set up with the appropriate sales tax authority, you could be liable for penalties and interest. The really good news is that once you understand the basics of sales tax, it becomes easy to handle properly.
In this blog post, we explain how the sales tax system works and what all business owners need to know to remain compliant and worry-free.
Understanding How Sales Tax Operates in Canada
The sales tax system in Canada can appear complicated due to having both federal and provincial tax systems. Businesses must understand both the type of taxes that apply to their province, how those taxes will affect what they charge their customers, and how to report the taxes when it comes to filing their taxes.
Federal GST framework
The federal government has implemented a 5% Goods and Services Tax (GST) to the country as a whole. Business owners will charge their customers the GST on their sales of taxable goods and services. They will also be able to claim GST input tax credits for any GST they pay when purchasing goods and services for their business.
Harmonized provinces
Several provinces in Canada have combined the GST and provincial sales tax to create a single Harmonized Sales Tax (HST) for their province. In these provinces, businesses will collect the HST as a single combined tax and will file their HST taxes the same as they would for their federal GST.
Separate provincial systems
There are still several provinces in Canada that operate and charge the provincial sales tax separate from GST. In these provinces, businesses may be required to have separate registration to collect tax, to report tax, and to remit tax to the provincial authorities.
How Different Goods and Services Are Taxed
Not all products/services will be treated the same when it comes to tax. Depending on the product or services being sold, it will fall under one of three taxation categories – fully taxable, zero-rated and exempt. It is extremely important to understand how each category of a product/service is classified.
Fully taxable transactions
Most products and services that a business sells will fall under the category of fully taxable. Businesses will charge GST or HST on the sale of goods/services such as clothing, electronics, consulting services and meals in restaurants.
Zero-rated categories (0% GST/HST)
Examples being basic groceries & some medical devices. Businesses will charge businesses tax on purchases made subject to the Zero-rated GST/HST rate, but can still claim the ITCs for the related purchases.
Exempt supplies and when no tax applies
Residential rent, Financial Services (most give services), and some healthcare services are also Exempt Supplies. No GST/HST applies to the purchase of these supplies by the supplier, nor can the supplier claim I.T.C’s for the cost of providing the supplier to the purchaser.

Do You Need to Register for Canada Sales Tax?
All businesses in Canada must register for provincial sales tax Canada when their revenue exceeds the $30,000 threshold for small suppliers in a period of 12 months. Once a business exceeds the small supplier threshold, it must register and start to charge customers the appropriate amount of tax on taxable supplies.
For smaller businesses that haven’t reached the $30,000 threshold, there can be advantages to registering voluntarily. Some of these advantages include being able to collect input tax credits for costs incurred, as well as appearing to be a more established business to other vendors and customers.
Understanding the sales tax rules in Canada can help to avoid missing returns or being penalized for being late.
