Reverse GST and PST calculator, Saskatchewan.
Got a total with tax already in it? Enter it and get the price before tax and the GST and PST that was added.
In Saskatchewan the combined rate is 5% GST + 6% PST = 11%. To remove it, divide the total by 1.11. Example: $133.20 ÷ 1.11 = $120.00 before tax, so $13.20 of the total is tax.

How the reverse calculation works
Saskatchewan has the lowest combined GST-plus-PST rate of the four GST-plus-provincial-tax provinces, 11% against 12% in BC and Manitoba and 14.975% in Quebec.
Pre-tax price = total ÷ 1.11. Tax = total − pre-tax price. Worked examples at the Saskatchewan rate:
- $133.20 total = $120.00 before tax, $6.00 GST and $7.20 PST.
- $55.50 total = $50.00 before tax, $2.50 GST and $3.00 PST.
What this tool assumes
This tool treats GST (5%) and PST (6%) as two separate taxes on the same pre-tax price, with a combined divisor of 1.11. The CRA table shows the two rates in separate columns; we could not retrieve a Saskatchewan government page that states the calculation base in words, so treat the 1.11 divisor as an assumption and check it against a receipt that prints both tax lines.

Frequently asked questions
How do I remove GST and PST from a Saskatchewan total?
Divide the total by 1.11. That is 1 plus the combined rate of 11%. The result is the price before tax; subtract it from the total to get the tax. $133.20 ÷ 1.11 = $120.00, so the tax is $13.20.
Why can't I just take 11% off the total?
Because the rate applies to the pre-tax price, not to the total. Taking 11% of $133.20 gives $14.65, but the real tax is $13.20. Dividing by 1.11 is the correct reverse.
Is the Saskatchewan combined rate 11%?
Yes: the CRA table lists 5% GST and 6% PST for Saskatchewan, so a total divides by 1.11 when both taxes apply. If an item carries GST only, reverse it at 5% with the custom-rate box.
Will the answer match my receipt to the cent?
Usually, but not always. A seller rounds the tax on its own invoice, sometimes line by line, and more than one pre-tax price can produce the same total once rounded. This tool rounds the pre-tax price to the nearest cent and makes the tax lines add back to your total. If the receipt prints the tax, trust the receipt.
Estimate only
This is arithmetic on the rate you choose. It does not know whether the items you bought were taxable, zero-rated, exempt or taxed at a different rate, and it does not look anything up from the CRA or any provincial register. Where a receipt prints its own tax lines, use those. Verify current rates with the CRA before invoicing.
