GST rates in New Zealand (2026)

15%standard

The standard rate of 15% applies to most goods and services. There is no reduced rate; certain supplies may be exempt or zero-rated. Locally, the tax is called Goods and Services Tax (GST). Registration / small-business threshold: NZD 60,000 turnover in 12 months.

Good to know

  • Since April 2023 “tax invoices” have been replaced by “taxable supply information”, which can be in any format; the familiar invoice layout still works.
  • GST registration is required once turnover exceeds $60,000 in a 12-month period.

How it’s calculated

VAT is charged as a percentage of the net (pre-tax) price. To add it, multiply the net amount by the rate; to find the net amount inside a tax-inclusive price, divide the gross amount by 1 plus the rate.

A common mistake is to remove VAT by subtracting the rate from the gross price (e.g. 119 − 19% = 96.39). That is wrong — the correct net amount is 119 ÷ 1.19 = 100.

  • Gross = Net × (1 + rate ÷ 100)
  • VAT = Net × rate ÷ 100
  • Net = Gross ÷ (1 + rate ÷ 100)
