Updated Checked by the Tax-Services.ca editorial team How we check
In Saskatchewan you charge two separate taxes on most taxable sales: the 5% federal GST and the 6% provincial sales tax (PST), for 11% in total. The catch is that they go to two different governments. The Canada Revenue Agency collects the GST, and the PST is a Saskatchewan tax that you deal with through the province.
How GST and PST work in Saskatchewan
Each tax is worked out on the pre-tax price and added on. On a $1,000 item the GST is $50 and the PST is $60, so the customer pays $1,110. No tax on tax here.
| Price before tax | GST 5% | PST 6% | Total |
|---|---|---|---|
| $100 | $5.00 | $6.00 | $111.00 |
| $500 | $25.00 | $30.00 | $555.00 |
| $1,000 | $50.00 | $60.00 | $1,110.00 |
| $5,000 | $250.00 | $300.00 | $5,550.00 |
Got a price that already includes tax? Take $500 as an example. The price before tax is $450.45, with $22.52 of GST and $27.03 of PST. You can run your own figures through the GST and PST calculator, which handles Saskatchewan, British Columbia and Manitoba.
Who deals with what?
This is the part that confuses new business owners, mostly because the same sale produces two tax lines, two sets of rules and two offices that may each want to hear from you at different times. GST/HST registration runs through the CRA and has a small supplier threshold of $30,000 of taxable sales over four consecutive calendar quarters. Under that, you aren’t required to register for GST/HST.
The PST is separate. It’s administered by the province, and its own rules decide who has to register and file. Don’t assume the $30,000 CRA threshold gets you out of the PST. We couldn’t open Saskatchewan’s own page in full from our tools, so read the provincial tax pages on saskatchewan.ca, or call the ministry, before you decide you’re exempt.
What gets taxed and what doesn’t
Not every sale carries both taxes. Some items are zero-rated or exempt for GST, and the province has its own list for PST. Food, children’s goods, services and used items can fall on different sides of these lists. The same product can be taxed in Saskatchewan and not in another province, so don’t copy the treatment from a supplier in Alberta or Ontario.
For a quick feel of the difference, a $1,000 sale in Alberta carries $50 of GST and nothing more. In Ontario it carries a 13% HST, or $130. In Saskatchewan it’s $110. The GST and HST calculator shows any province side by side.
What goes wrong with the two taxes
The big one is charging one tax and forgetting the other. A sole proprietor under $30,000 who correctly skips GST may still have PST to think about. The reverse happens too, when a business charges both at the till and then only remits the GST.
Another is mixing up the direction of the math. If you backed out tax from a total, you can’t just take 11% off. Divide by 1.11. Five hundred dollars including tax is $450.45 before tax, not $445. And watch your records. You’ll want one line for each tax on every invoice, since they go to two places.
What about selling into Saskatchewan from another province, where you might have no shop, no staff and no office in the province at all? That’s a separate question with its own rules, and it’s not one we could settle from public pages, so ask the province.
If your work is self-employment, remember that sales tax is only part of the picture. Your income is taxed separately, and the self-employed tax calculator is a better place to start for that.
Where the numbers come from
The 5% GST and the small supplier threshold come from Canada Revenue Agency pages. The 6% Saskatchewan PST rate comes from the Government of Saskatchewan’s provincial sales tax page. All figures are for 2026, checked in September 2026. Nothing here replaces the provincial bulletins that set out which goods and services are taxable.
