How to calculate GST in Singapore
- To add GST: price before tax × 1.09 = price including tax. For example, 100.00 × 1.09 = 109.00.
- To remove GST: price including tax ÷ 1.09 = price before tax. For example, 109.00 ÷ 1.09 = 100.00.
- The tax inside a price that includes it: price including tax × 9 ÷ 109. For 109.00 that is 9.00.
