NZ GST Registration Threshold 2026: The $60,000 Rule Explained for New Zealand Business Owners

TL;DR: In New Zealand, GST registration is compulsory once your taxable turnover exceeds NZ$60,000 in any 12-month period. The GST rate is 15%. Returns are filed with Inland Revenue (IRD) on 2-monthly or 6-monthly cycles. Voluntary registration is allowed below the threshold.

What Is the NZ GST Registration Threshold in 2026?

The NZ GST registration threshold is NZ$60,000 in taxable supplies made in any 12-month period — either the past 12 months or the next 12 months if you reasonably expect to exceed it. Once you cross this threshold, you must register for GST with Inland Revenue (IRD) within 21 days.

New Zealand's Goods and Services Tax is governed by the Goods and Services Tax Act 1985. The $60,000 threshold has remained unchanged for many years and applies to most business types — sole traders, partnerships, companies, and trusts alike. This is not a calendar-year rule; IRD looks at any rolling 12-month period, which means a sudden surge in a single quarter can trigger the obligation.

Why does this matter? Missing your registration window exposes your business to backdated GST liability — IRD can require you to account for GST on all supplies made after you should have registered, even if you never collected it from customers. The obligation falls on you, not your buyers.

Key GST Facts for New Zealand Businesses

The Prospective Test — Don't Wait Until After the Fact

Most business owners think about GST registration only after they've already exceeded $60,000. But IRD also requires registration when you have reasonable grounds to believe your taxable supplies will exceed $60,000 in the next 12 months. If you sign a large contract, open a new location, or see strong forward bookings, that prospective test can trigger compulsory registration before you've invoiced a single dollar.

KARR's threshold tracker monitors your cumulative taxable turnover in real time and alerts you when you approach the $60,000 mark — giving you the 21-day window you need to register without scrambling.

When Should You Register for GST Voluntarily?

Voluntary GST registration is available to any business making taxable supplies, even below $60,000. It makes financial sense when your input tax credits (GST on purchases) are significant, when your customers are GST-registered businesses, or when you want to appear more established.

For a business spending heavily on GST-inclusive inputs — equipment, rent, professional services — voluntary registration lets you claim back the 15% GST embedded in those costs. If your customers are B2B and also registered, they can claim the GST you charge them, so being registered is neutral or beneficial for those relationships.

When voluntary registration is worth considering:

• You buy significant stock, equipment, or assets with GST included
• Most of your customers are GST-registered businesses
• You're starting up and expect to cross $60,000 within 12 months
• You want to claim back GST on startup costs before you start trading

When voluntary registration may not suit you:

• Most of your customers are end consumers who cannot reclaim GST (your prices effectively increase by 15%)
• Your input costs are low relative to turnover
• You want to keep administration simple at very low revenue levels

How to Register for GST with IRD

Registering for GST in New Zealand requires submitting an application to Inland Revenue, either online through myIR (IRD's online services portal) or by completing and posting an IR360 form. IRD will issue you a GST registration number, which you must display on all tax invoices.

GST Registration Process Step-by-Step

1. Confirm your obligation or decision — Calculate rolling 12-month taxable supplies. Confirm you are over $60,000 or choosing voluntary registration.
2. Log into myIR at ird.govt.nz or complete IR360 (paper form).
3. Choose your filing frequency — 2-monthly is the default; 1-monthly suits businesses with consistent GST refunds; 6-monthly suits businesses with turnover under $500,000 and straightforward GST positions.
4. Choose your accounting basis — Invoice basis (GST at invoice date) or payments basis (GST when cash received; available if turnover is under $2 million).
5. Receive your GST number — IRD issues your registration number, typically within a few working days for online applications.
6. Start issuing tax invoices — All invoices for supplies over NZ$50 (exclusive) must be tax invoices showing your GST number and the GST amount.

Invoice Basis vs. Payments Basis

Accounting Basis	When GST Is Accounted For	Who Can Use It	Best For
Invoice basis	Date of invoice (regardless of payment)	All registered businesses	Businesses with prompt payment
Payments basis	Date cash is received/paid	Turnover under NZ$2 million	Businesses with slow-paying customers
Hybrid basis	Mix of invoice and payments	Specific IRD approval required	Uncommon — specialist situations

KARR supports both invoice-basis and payments-basis GST accounting. When you record a transaction using the "What Happened?" guided wizard, KARR automatically applies the correct GST treatment based on your registered accounting basis — no manual journal entries required.

Filing Your IRD GST Return

Once registered, your GST return (form GST101A or filed directly through myIR) is due by the 28th of the month following the end of your GST period. For 2-monthly filers, this means six returns per year; for 6-monthly filers, two returns per year.

Critical due dates for 2-monthly filers (periods ending in 2026):

• Period ending 28 February 2026 → return and payment due 28 March 2026
• Period ending 30 April 2026 → return and payment due 28 May 2026
• Period ending 30 June 2026 → return and payment due 28 July 2026
• Period ending 31 August 2026 → return and payment due 28 September 2026
• Period ending 31 October 2026 → return and payment due 30 November 2026
• Period ending 31 December 2026 → return and payment due 28 January 2027

What goes into your GST return:

• Total sales and income (including GST)
• GST collected on taxable supplies
• Total purchases and expenses (including GST)
• GST you can claim (input tax credits)
• Net GST to pay, or refund owing to you

KARR prepares a complete GST return summary from your recorded transactions, mapping every line to the corresponding box in the IRD GST return. You can export the completed return data directly to myIR or use it as a verified worksheet for manual filing.

GST Rate, Zero-Rating, and Exempt Supplies

New Zealand GST applies at 15% on all taxable supplies unless the supply is zero-rated or exempt. Zero-rated supplies are taxable at 0% — the supplier does not charge GST but can still claim input tax credits. Exempt supplies sit outside the GST system entirely.

Common zero-rated supplies:

• Exported goods and services (supplied to non-residents outside New Zealand)
• Sales of going concerns (entire business sold as a going concern, where both parties are GST-registered)
• Certain land transactions between GST-registered parties
• Financial services provided to non-residents in certain circumstances

Exempt supplies (no GST charged, no input credits claimable):

• Financial services (interest, lending, insurance in most cases)
• Residential rental income
• Fine metals (in certain forms)

If your business makes a mix of taxable and exempt supplies, you can only claim the proportion of input tax credits that relates to your taxable supplies. This partial-use calculation is required under the GST Act and must be documented.

Penalties, Late Filing, and IRD Compliance

IRD imposes late filing penalties and use-of-money interest on overdue GST. A late filing penalty applies immediately if a return is not filed by the due date. Subsequent failure-to-file penalties accrue in escalating steps under the Tax Administration Act 1994.

Use-of-money interest runs from the day after payment was due until the date IRD receives it. IRD publishes the current interest rates on ird.govt.nz — these rates change periodically, so always verify the current rate on the IRD website rather than relying on third-party sources.

Common GST compliance mistakes in New Zealand:

• Failing to register within 21 days of crossing the $60,000 threshold
• Missing a GST return due date
• Claiming input credits on exempt supplies
• Not issuing a valid tax invoice (missing GST number, missing GST amount for invoices over $50)
• Treating mixed-use assets as fully deductible
• Not accounting for GST on imported services (reverse-charge rules)

KARR flags potential GST errors before you file — including uncategorised transactions, missing GST codes, and supplies that appear inconsistently classified — so you can review and correct before IRD does.

Frequently Asked Questions

Q: What is the GST threshold in New Zealand?

The NZ GST registration threshold is NZ$60,000 in taxable supplies in any 12-month period. This is a rolling threshold — not a calendar year — so any consecutive 12-month window counts. Once you exceed or expect to exceed $60,000, registration with IRD is compulsory.

Q: What is the GST rate in New Zealand?

The GST rate in New Zealand is 15%, set under the Goods and Services Tax Act 1985. This single rate applies to most goods and services. Some supplies are zero-rated at 0% (such as exports) and some are exempt (such as financial services and residential rent).

Q: How long do I have to register for GST once I cross the threshold?

You must apply to register for GST with Inland Revenue within 21 days of the date you exceeded the $60,000 threshold or the date you had reasonable grounds to believe you would exceed it in the next 12 months. Late registration can result in backdated GST liability.

Q: How often do I need to file a GST return with IRD?

Most businesses file GST returns every 2 months. Businesses with turnover under NZ$500,000 can apply for 6-monthly filing. Businesses that regularly receive GST refunds can apply for monthly filing. Returns and payments are due by the 28th of the month after the filing period ends.

Q: Can I register for GST voluntarily if I'm under $60,000?

Yes. Any business making taxable supplies can register for GST voluntarily, regardless of turnover. Voluntary registration allows you to claim input tax credits on your business purchases. It makes most sense when your input costs carry significant GST or when your customers are other GST-registered businesses.

Q: What is the difference between invoice basis and payments basis GST?

Under invoice basis, you account for GST when you issue or receive an invoice, regardless of when cash changes hands. Under payments basis, GST is accounted for when you actually receive or make payment. Payments basis is available if your turnover is under NZ$2 million and is useful if you have slow-paying customers.

Q: What happens if I don't register for GST when I should?

If you fail to register when required, IRD can backdate your registration to the date you should have registered and assess GST on all taxable supplies made since then — even if you never collected GST from customers. Late filing penalties and use-of-money interest also apply. The liability falls on the supplier.

Q: Does GST apply to exported goods and services?

Exported goods and services are generally zero-rated at 0% GST, meaning you do not charge GST to overseas customers but can still claim input tax credits on related business costs. Specific conditions apply — the supply must be made to a non-resident outside New Zealand. Verify your specific situation with a tax adviser or refer to IR420 guidance on ird.govt.nz.
