Saskatchewan is the strictest province in Canada for provincial sales tax, and it catches more online sellers than any other. The reason is simple: there is no minimum. Most provinces let small sellers off the hook until they hit a sales threshold. Saskatchewan does not.
The rule: register from the first sale
Saskatchewan PST is 6%. If you make a taxable sale to a Saskatchewan customer, you are expected to be registered and collecting it, starting with the very first one. There is no small-seller exemption to fall back on, so “I only sell a little into Saskatchewan” is not a reason to skip it.
This applies whether your business is in another province or outside Canada entirely. Saskatchewan looks at whether you sell into the province, not where you are based.
What actually triggers it
You are on the hook if, in the normal course of business, you:
- Make your products available for sale to Saskatchewan customers,
- Accept orders from Saskatchewan, and
- Deliver the goods into Saskatchewan.
Notice what is not on that list: where your inventory sits. Unlike some provinces, Saskatchewan does not care whether you ship from a local warehouse or from across the border. Selling into the province is enough.
The one thing that gets you out of it
If you sell only through a marketplace like Amazon, the marketplace collects and remits Saskatchewan PST for you. So a pure Amazon seller usually does not need to register here.
The moment you add a direct channel, though, that cover disappears. Sell the same products through Shopify, your own website, or wholesale into Saskatchewan, and you are back to registering from the first sale.
What registration involves
You register through Saskatchewan’s online system and receive a PST number. From there you charge 6% on taxable sales to Saskatchewan customers and file returns on the schedule the province assigns, usually annually for smaller sellers. Even a period with no sales into Saskatchewan needs a return once you are registered.
Frequently asked questions
Do I really have to register if I only sell a little into Saskatchewan?
For direct sales, yes. There is no minimum, so even a small amount of direct sales into the province creates a registration requirement.
I am a US seller. Does Saskatchewan apply to me?
Yes, the same way it applies to a Canadian seller. If you make direct sales into Saskatchewan, you register, regardless of where you ship from.
Does Amazon cover my Saskatchewan sales?
For your Amazon orders, yes. For sales through your own store or wholesale, no. Those are your responsibility.
