GST rates in New Zealand
| Rate | Applies to (examples) |
|---|---|
| 15% | Standard rate: most goods and services |
| 0% | exports, sales of a going concern, and some financial services are exempt |
In New Zealand the tax is called GST. To add 15%, multiply the net price by 1.15: $100.00 becomes $115.00. To remove it, divide the gross price by 1.15: $100.00 including GST is $86.96 net plus $13.04 GST. A common mistake is to take 15% off the gross price, which removes too much; the GST share of a gross price is 3/23, or 13.04%.
Businesses must register for GST when turnover exceeds NZ$60,000 in 12 months. Because 15% is added to the net price, the GST in a GST-inclusive price is exactly 3/23 of it.
