Common GST questions

What is the GST rate in New Zealand?

The GST rate in New Zealand is 15%. It has been 15% since 1 October 2010 when it was raised from 12.5%.

How do I add GST to a price in NZ?

To add 15% GST to an ex-GST price, multiply the amount by 1.15. For example, $100 + GST = $100 × 1.15 = $115. The GST component is $15.

How do I remove GST from a GST-inclusive price?

To remove GST from a GST-inclusive price, divide by 1.15. For example, $115 ÷ 1.15 = $100 ex-GST. The GST component is $115 − $100 = $15.

What goes in Box 5 and Box 6 of the NZ GST return?
