Do I Need to Register for GST in NZ?

If you’re running a business in New Zealand, you’ve probably heard about GST (Goods and Services Tax). But do you need to register for it? The answer depends on your turnover, business activities, and whether you want to claim GST on expenses.

Registering for GST can bring benefits but also adds compliance requirements, so it's important to understand when and why you should register. Let’s break it down in simple, practical terms.


What is GST?

GST (Goods and Services Tax) is a 15% tax applied to most goods and services sold in New Zealand. If you're GST-registered, you must charge GST on your sales and pay it to the Inland Revenue Department (IRD). On the plus side, you can also claim back GST on your business expenses, reducing costs.


When Do You Have to Register for GST?

You must register for GST if any of the following apply:

  • Your business earns (or expects to earn) more than $60,000 in turnover within any 12-month period (not just a calendar year, but any rolling 12 months).
  • You charge GST-inclusive prices to customers.
  • You want to claim GST on your expenses, even if you're under the threshold (voluntary registration).

If you don’t register and you exceed the threshold, the IRD can charge penalties and backdate your GST obligations, meaning you could owe unpaid GST from previous months.


Should You Register Voluntarily?

Even if you’re under the $60,000 threshold, you might still choose to register for GST. Here’s why:

Pros of Registering for GST Early:

  • Claim GST on business expenses – This reduces your overall costs.
  • Looks more professional – Some businesses and clients prefer working with GST-registered companies.
  • Easier to transition – If your income is growing, registering early avoids last-minute compliance stress.

Cons of Registering for GST Early:

  • More paperwork – You’ll need to file GST returns regularly.
  • Cash flow impact – You must charge 15% more on sales, which could affect pricing competitiveness.


How to Register for GST in NZ

Registering for GST is a straightforward process and can be done in a few ways:

  • Online via myIR – The fastest method is through the IRD’s myIR portal.
  • Through a tax agent – An accountant can handle registration for you.
  • Phone or in-person – You can contact the IRD directly to register.


GST Return Filing & Compliance

Once registered, you’ll need to file GST returns and pay GST to the IRD. You can choose how often you file:

  • Monthly – Best for high-turnover businesses that prefer regular tracking.
  • Two-monthly (standard) – The most common filing frequency.
  • Six-monthly – Available for businesses with turnover under $500,000 per year, ideal for lower transaction volumes.

Your GST return due dates depend on your chosen filing period, and late payments can result in penalties. Using accounting software like Xero or MYOB can simplify GST tracking and filing.


Final Thoughts

If your business is growing and approaching the $60,000 threshold, it’s time to start thinking about GST registration. Voluntary registration can also be beneficial, depending on your expenses and industry.
