How to calculate GST in New Zealand
- To add GST: price before tax × 1.15 = price including tax. For example, 100.00 × 1.15 = 115.00.
- To remove GST: price including tax ÷ 1.15 = price before tax. For example, 115.00 ÷ 1.15 = 100.00.
- The tax inside a price that includes it: price including tax × 15 ÷ 115. For 115.00 that is 15.00.
