Understanding PST Exemptions for Alberta Businesses

One of Alberta's greatest advantages for small businesses is the absence of a Provincial Sales Tax (PST). While other provinces charge between 6% and 10% PST on top of the federal 5% GST, Alberta businesses only collect 5% GST on taxable goods and services. But the situation gets more complex when you sell across provincial lines.

Alberta's Tax Advantage

Alberta is one of only three Canadian jurisdictions without PST (along with the territories). This means lower costs for consumers and simpler tax compliance for businesses. A Calgary restaurant, for example, charges only 5% GST rather than the 13% HST charged in Ontario. This price advantage can be significant for businesses serving consumers.

When Provincial Sales Tax Applies to Alberta Businesses

If your Calgary business sells goods or services to customers in provinces with PST or HST, you may be required to collect those provincial taxes. The rules vary by province:

• HST provinces (Ontario, Nova Scotia, New Brunswick, Newfoundland, PEI): You charge HST at the applicable rate (13-15%) on sales delivered to customers in these provinces.
• BC, Saskatchewan, Manitoba: These provinces have separate PST. Generally, you only need to collect their PST if you have a physical presence or meet certain registration thresholds in that province.
• Quebec: QST has its own registration requirements for out-of-province sellers exceeding $30,000 in annual sales to Quebec customers.

E-Commerce Complications

For Calgary businesses selling online, the place-of-supply rules determine which tax applies. Generally, the tax rate is based on the delivery destination, not your location. If you ship a product from Calgary to a customer in Toronto, HST at 13% applies — not Alberta's 5% GST alone.

How This Affects Your Bookkeeping

Multi-province sales require your accounting system to track which tax rates were applied to which sales. Your GST return needs to accurately reflect only the federal portion, while provincial taxes may require separate filings. This is where proper bookkeeping software and professional support become essential.
