Frequently asked questions
What is the GST rate in New Zealand?
New Zealand's Goods and Services Tax (GST) is levied at a flat rate of 15% on most goods and services. The rate was raised from 12.5% to 15% in October 2010. Unlike many other countries, New Zealand has very few GST exemptions — financial services and certain residential rents are the main exceptions. This broad base with a single rate makes NZ's GST one of the most comprehensive consumption tax systems in the world. Nearly all retail prices in NZ are displayed GST-inclusive.
How do I extract GST from a GST-inclusive price?
To find the GST component in a GST-inclusive price, divide the total price by 23 and multiply by 3 (at 15% GST). Alternatively, multiply by 3/23 or approximately 0.1304. For example, a $115 GST-inclusive price contains $15 GST ($115 × 3/23 = $15). The formula works because GST-inclusive price = GST-exclusive price × 1.15, so GST = inclusive price × 0.15/1.15 = inclusive price × 3/23. Our calculator does this automatically when you select "Extract GST."
Who needs to register for GST in New Zealand?
Any business or self-employed person with annual turnover exceeding $60,000 must register for GST with IRD. Registration is optional for businesses with turnover below $60,000. Once registered, you charge GST on your sales (output tax) and can claim back GST on your business purchases (input tax). The difference is paid to or refunded by IRD, depending on whether output tax exceeds input tax. GST returns are filed monthly, two-monthly, or six-monthly depending on your turnover.
Are there any GST-exempt goods in New Zealand?
New Zealand's GST base is unusually broad, with very few exempt supplies. The main exemptions include: financial services (lending, insurance premiums, share transactions), residential rent (but commercial rent is GST-applicable), fine metals (gold, silver bullion), and certain donations and fundraising activities by non-profits. Notably, food and groceries are not exempt in NZ — unlike Australia, the UK, and Canada, which zero-rate basic food items. This broad base is a key feature of NZ's tax system, generating significant revenue at a relatively low rate.

How GST works in New Zealand
Goods and Services Tax (GST) is a consumption tax applied to most goods and services sold in New Zealand at a flat rate of 15%. Unlike a sales tax system (used in the US) where tax is added at the point of sale, GST is a value-added tax collected at each stage of the supply chain, with businesses claiming back the GST they paid on their inputs. The result is that only the final consumer bears the full cost of GST. New Zealand introduced GST in 1986 at 10%, raised it to 12.5% in 1989, and increased it again to 15% in October 2010. The broad base and single rate make NZ's system among the simplest in the OECD.
GST for New Zealand businesses and freelancers
For New Zealand businesses and self-employed individuals, GST is a key tax obligation. Once your taxable turnover exceeds $60,000 per year, GST registration is compulsory. Registered businesses collect GST on sales (output tax), claim GST back on business expenses (input tax), and remit the net difference to Inland Revenue. The filing frequency depends on turnover: monthly (over $24 million), two-monthly (most businesses), or six-monthly (under $500,000 turnover, optional). Keeping accurate records of GST collected and paid is essential. Penalties apply for late filing or payment. For small businesses under the $60,000 threshold, voluntary registration can be beneficial if your suppliers are GST-registered, as you can claim back input tax on your purchases.
