How to calculate GST in Alberta

  • To add GST: price before tax × 1.05 = price including tax. For example, 100.00 × 1.05 = 105.00.
  • To remove GST: price including tax ÷ 1.05 = price before tax. For example, 105.00 ÷ 1.05 = 100.00.
  • The tax inside a price that includes it: price including tax × 5 ÷ 105. For 105.00 that is 5.00.

Alberta GST: frequently asked questions

What is the GST rate in Alberta?

The standard GST rate in Alberta is 5%.

How do I add GST to a price?

Multiply the price before tax by 1.05. For example, 100 plus 5% GST is 105.00.

How do I remove GST from a price?

Divide the price including GST by 1.05. For example, 105.00 including 5% GST is 100.00 before tax. Do not just take 5% off the total, because that gives the wrong answer.
