How much is GST in NZ?

GST is charged at a rate of 15%. It is a tax added to the price of most goods and services, including imports. 

How to calculate GST?

When adding 15% to the price it is relatively easy, just multiply the amount by 1.15.

For example, $100 x 1.15 = $115. This is the price inclusive of GST.

Reverse GST calculations are more difficult.

To figure out how much GST was included in the price multiply the GST- inclusive price by 3 then divide by 23.

For example, $115 x 3 / 23 = $15

To work out the price without GST you have to divide the amount by 1.15

For example, $115 / 1.15 = $100
