Understanding Provincial Sales Tax: What Businesses Need to Know Outside of GST/HST 0

Posted On October 23, 2025, by Ann-Marie Powell

While GST/HST is the most commonly discussed sales tax in Canada, it is not the only one. Several provinces—Quebec, Manitoba, Saskatchewan, and British Columbia—administer their own provincial sales taxes independently of the federal system. If you are doing business across provincial lines, it is critical to understand each province’s specific rules, thresholds, and registration requirements.

This article builds on our previous post, Place of Supply: Determining the Right GST/HST Rate,” and breaks down key provincial sales tax systems outside the GST/HST regime, offering practical advice for staying compliant when operating in multiple jurisdictions.

Quebec (QST)

In Quebec, businesses may be required to register for both GST/HST and QST (Quebec Sales Tax). While GST/HST is administered federally by the Canada Revenue Agency (CRA), QST is administered separately by Revenu Québec.

Businesses located outside of Quebec must register for QST if they meet certain thresholds. As of September 1, 2019, non-resident businesses to Quebec—that is, businesses without a physical presence in the province—that supply taxable goods or services to specified consumers in Quebec must register if their sales exceed $30,000 annually.

There is a distinction between:

  • Specified QST registrants (for non-residents that sell to Quebec consumers), and
  • Regular QST registrants (typically for businesses with a physical presence or employees in Quebec).

Revenu Québec handles registration, collection, remittance, and compliance for QST. It is a separate system from CRA, and you must file returns online through Revenu Québec, either using their express service with an access code or via your “My Account”. You can also file returns through your financial institution. Please note you can only claim Quebec input tax credits if you are registered as a regular QST registrant.

Once registered, businesses must:

  • Charge 9.975% QST on taxable supplies to Quebec customers.
  • Display both the GST number and QST number on invoices.
  • Maintain proper records and file separate QST returns.

Businesses operating in Quebec must be diligent in managing compliance with both federal and provincial systems.

Manitoba (RST)

Manitoba’s Retail Sales Tax (RST) is a standalone tax system separate from GST/HST, operated by Manitoba Finance. The current RST rate is 7%.

RST applies primarily to the sale of tangible personal property and certain services such as:

  • Telecommunications
  • Insurance contracts
  • Software
  • Leases of goods

Businesses must ensure they understand which items are taxable and whether their services fall within scope.

Out-of-Province Seller Requirements

Manitoba requires out-of-province businesses to register and collect RST if they:

  • Sell taxable goods to Manitoba customers for their own consumption or use in Manitoba (registration is not required if the goods are purchased solely for resale)
  • Solicit and accepts orders originating in Manitoba
  • Deliver or ship the goods into the province
  • Or the seller holds inventory of taxable goods in the province, available for sale to Manitoba customers.

This includes online retailers and remote sellers who may not have a physical presence in Manitoba but make taxable sales to consumers in Manitoba.

Software—both pre-packaged and customized—is generally taxable. Remote sellers of digital products may also be required to register and collect RST, depending on how the product is delivered and used in Manitoba. Effective January 1, 2024 Manitoba RST will also apply to cloud computing services, which includes services such as remote computing, date storage and subscription-based software.

Business can register and file returns for Manitoba RST through TAXcess.

Saskatchewan & British Columbia (PST)

Though both provinces operate Provincial Sales Tax (PST) systems, each has its own rules and nuances. In general, PST is separate from GST/HST, and each province administers it independently from federal tax. Out-of-province sellers may need to register if they sell taxable goods or services to customers within either province, even if they do not have a physical presence there.

Saskatchewan

Saskatchewan levies PST of 6% on taxable goods and services, and the Saskatchewan Government administers it. Out-of-province businesses must register if they make retail sales in the province, including the sale or lease of tangible personal property, taxable services, or contracts of insurance that are acquired for use or consumption in or relating to Saskatchewan.

Retail sales in the province include retail sales by persons who do not otherwise carry on business in Saskatchewan and include situations where a person selling or providing tangible personal property to a consumer or user:

  • Makes tangible personal property available for purchase by persons in Saskatchewan;
  • Accepts orders to purchase tangible personal property that originate in Saskatchewan; and,
  • Causes the tangible property to be delivered in Saskatchewan.

Tangible personal property generally refers to goods and also includes data, information, or material that landlines, wires, fibre optic cables, satellites, and similar means transfer, transmit, or distribute. This therefore applies to e-commerce businesses, software providers, and digital service platforms.

Businesses can register and file their Saskatchewan PST returns through Saskatchewan eTax Services (SETS).

British Columbia

Businesses located outside British Colombia (BC) but within Canada must register to collect and remit BC PST if all of the following conditions apply on a regular basis:

  • Sell taxable goods or software to customers in BC
  • Solicit and accept orders to purchase taxable goods or software from customers located in BC
  • Deliver taxable goods or software to a location in British Columbia, either shipped physically or electronically.
  • Exceed the minimum BC threshold of gross revenue in the previous 12 months from all sales, including provisions of software and telecommunication services to BC customers of $10,000

Since July 1, 2022 BC has also required ‘online marketplace facilitators’ such as Amazon to register to collect and remit PST on sales and leases facilitated within BC.

Businesses in industries such as construction, technology, and telecommunications may face unique compliance challenges. For example, PST may apply differently depending on whether materials are purchased for resale, incorporated into real property, or used in the provision of taxable services.

British Columbia applies PST of 7% on the sales of most taxable goods and services and businesses can register and file their returns through eTaxBC.

 

Practical Tips for Managing Provincial Sales Tax

Navigating multiple provincial tax systems can be complex, especially for growing businesses. Below are some key considerations:

Determining Where to Register

You must evaluate whether your business has a physical presence, ships or delivers products, or sells digital goods or services into a province. In many cases, economic activity alone may trigger registration obligations, particularly for Quebec, Manitoba, Saskatchewan, and British Columbia.

Best Practices for Managing Compliance

  • Keep detailed records of where your customers are located and how goods or services are delivered.
  • Regularly review the thresholds and registration rules in each province where you operate.
  • Ensure your invoicing includes the correct tax rate and registration numbers for each jurisdiction.

Use of Accounting Software and Automation

Modern accounting platforms can assist with:

  • Charging the correct provincial tax rates
  • Tracking sales by region
  • Automating returns and remittances

Look for accounting software that supports multi-jurisdictional tax settings or consider working with an accountant to build a customized compliance workflow.

Final Thoughts

Managing provincial sales tax obligations goes beyond understanding GST/HST. If your business sells across provincial borders—especially to Quebec, Manitoba, Saskatchewan, or British Columbia—you need to ensure you are charging and remitting the correct taxes in each jurisdiction.

These provincial systems are distinct and independently administered, which means registration, filing, and compliance are not centralized. As a result, many businesses benefit from professional support to avoid missteps and penalties.
