How it works

New Zealand levies a standard 15% GST on most supplies. Adding 15% to a net amount of $100.00 NZD results in $15.00 NZD GST for a $115.00 NZD gross total. To remove GST from $115.00 NZD, divide by 1.15 to reach $100.00 NZD.

Questions

What is the GST tax fraction in New Zealand?

Because prices are 115% of net value, the GST portion of any inclusive price is 15 ÷ 115, which simplifies to the fraction 3/23.

Are any sales exempt or zero-rated from NZ GST?

Exports of goods and services, overseas financial services, and sales of a going-concern business are generally zero-rated (0%).

Do consumer prices in New Zealand already include GST?

Yes. In New Zealand, prices shown to consumers usually include GST.
