GST Registration for New Companies in NZ: What You Must Do in the First 60 Days
Starting a new company in New Zealand? GST registration is one of the first compliance decisions you face. This guide explains when you must register, when you should register early, and how to get it right from day one.
Do I need to register for GST?
GST (Goods and Services Tax) registration in New Zealand is mandatory once your business earns more than NZ$60,000 in a rolling 12-month period. If you expect to earn over that threshold in your first year, you need to register before you hit it, not after.
The rule applies to the total turnover of your business, not your profit. If you charge NZ$80,000 for services in your first year, you are required to be registered for GST even if your actual profit is much less.
What happens if I register too late?
Registering for GST late is a common and costly mistake for new companies. If you pass the NZ$60,000 threshold without registering, you owe GST on all taxable supplies from the moment you became required to register. This means you could owe GST on income you already spent, without having collected it from customers.
Inland Revenue can also impose penalties and interest on late registrations. The safest approach is to register as soon as your projected turnover approaches the threshold, or to register voluntarily from day one if you know your revenue will be significant.
Should I register early, even if I am below the threshold?
Many new businesses choose to register for GST voluntarily, even when they are below the NZ$60,000 threshold. There are several reasons this makes sense:
- Claim GST back on business expenses. If you are buying equipment, software, vehicles, or professional services, you can claim back the GST component on those purchases once you are registered. This can be a meaningful cash flow benefit in the startup phase.
- Look more established. Quoting GST-inclusive prices signals to other businesses and clients that you are a legitimate, trading entity rather than a casual side project.
- Avoid the retroactive headache. Registering early and staying compliant from the start is far simpler than trying to reconstruct records after the fact.
When should I not register early?
Voluntary GST registration adds compliance obligations. You must file GST returns (either monthly, two-monthly, or six-monthly), charge GST on all taxable supplies, and keep detailed records. If your business is genuinely small and unlikely to approach the threshold for a while, the compliance overhead may outweigh the benefit of early registration. Discuss this with an accountant who knows your situation.
How to register for GST in New Zealand
GST registration is done through Inland Revenue's myIR portal. You will need:
- Your company's IRD number (you get this when the company is incorporated, or you can apply online through myIR)
- Details of your business activity, expected turnover, and accounting basis (invoice or payments)
- Your bank account number for any GST refunds
Most registrations are processed within a few days. Once registered, you will need to start charging GST on your invoices immediately and file returns on your chosen cycle.
What is the right accounting basis?
New Zealand GST can be accounted for on either an invoice basis (when you send or receive the invoice) or a payments basis (when the money actually moves). For new businesses, the payments basis is often easier to manage from a cash flow perspective, but there are eligibility rules. Your accountant can advise which is right for your business.
What else needs to happen in the first 60 days?
GST registration is often the first compliance task for a new company, but it is not the only one. In the first 60 days, most new companies also need to:
- Decide on a company structure for tax purposes (retained earnings vs. salary vs. dividends)
- Set up accounting software (Xero, MYOB, or similar) and a separate business bank account
- Register as an employer if you are hiring staff, even one person or part-time
- Sort out provisional tax obligations if you are likely to have significant taxable income
- Arrange any required business insurance (public liability, professional indemnity, or asset cover)
Getting these right from the start saves considerable time and money later. Most of these tasks are straightforward for an accountant or bookkeeper who works with new NZ companies regularly.
