GST

Does your business need to register for GST in New Zealand?

GST is a 15% tax added to the price of most goods and services in New Zealand. Whether you have to charge it comes down to one number — and getting the timing wrong is an expensive mistake to unwind.

Goods and Services Tax applies to almost everything sold in New Zealand. If you run a business here, or sell goods and services into the country, GST may well apply to you. Deciding whether to register is one of the first real tax decisions a business owner makes, and one of the easiest to get wrong.

The short version
  • Registration is compulsory at $60,000 turnover in any 12-month period
  • That is looking back over the past 12 months, or forward to the next 12
  • You have 21 days from the point you realise you will cross it
  • Below $60,000 you can register voluntarily — sometimes worth it, often not
  • Once registered you charge GST, file returns, and claim GST back on costs

1. The $60,000 threshold

You must register for GST if you are carrying out a taxable activity and your turnover is $60,000 or more in the past 12 months, or you reasonably expect it to reach $60,000 in the next 12 months.

It is a rolling 12-month test, not a financial-year test. A strong few months can trigger it well before 31 March.

The forward-looking half of that rule is the one people miss. If you sign a contract in June that will clearly take you past $60,000 by the following June, the obligation starts then — not when the money actually lands. You can work out where you sit with our free GST calculator.

2. What counts as a taxable activity

A taxable activity means regularly supplying goods or services for payment. That covers far more than a shopfront:

  • Selling products, online or in person
  • Consulting, contracting and freelance work
  • Leasing commercial property
  • Running online or subscription services

Turnover means your gross sales — not your profit. A contractor billing $70,000 who takes home $45,000 after expenses is still over the threshold.

3. When you must register below $60,000

If you already add GST to your prices, Inland Revenue expects you to be registered, regardless of turnover. Charging GST while unregistered is a straightforward compliance problem. Some industries, and certain online marketplaces, also have their own rules.

4. Overseas and non-resident businesses

Non-resident businesses supplying more than $60,000 into New Zealand in a 12-month period may need to register and collect GST. Remote digital services, low-value imported goods and marketplace sales all have specific rules that can trigger registration well before you have any physical presence here.

5. Should you register voluntarily?

Under $60,000 it is your choice, and the answer depends on who your customers are.

Low costs, small margins, few expensesWait

Selling to businesses, GST is invisible to your customer — they claim it back — while you get to claim GST on your own costs. Selling to the public, adding 15% either raises your price or cuts your margin.

6. What changes once you register

  • You charge GST on all taxable sales
  • You file GST returns on your chosen frequency
  • You pay IRD the net GST, or receive a refund
  • You keep records that support every figure on the return
The trap: spending the GST

GST you collect is not revenue. It sits in your bank account looking like yours until the return is due. Six-monthly filing makes this worse, because you hold it longer. Move it to a separate account the day it arrives and the problem disappears.

The bottom line

Once you meet the rules, registration is not optional and backdating is messy. If you are approaching $60,000, or unsure whether what you do counts as a taxable activity, get it checked before you cross the line rather than after.
