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|
