How to register as self-employed in NZ (2026) — the complete checklist
TL;DR
In New Zealand you don't apply to a 'self-employed register' — you just start trading as a sole trader under your own IRD number and tell IRD you're now earning self-employed income. This is the complete 2026 checklist: the seven things to actually do, in order, what each costs, what you can skip, and the first-year tax trap that catches almost everyone.
Start here
There is no 'register as self-employed' button
People search for how to 'register as self-employed' expecting a single government form. There isn't one. Becoming a sole trader in NZ means doing a handful of small things — most of them free — and the only mandatory one is telling IRD. This checklist puts them in the right order.
The 7 steps, in order
- Choose your structure. For ~90% of new operators that's a sole trader — free, instant, uses your personal IRD number. Only incorporate a company if you have a specific reason. Sole trader vs limited company, decided.
- Tell IRD you're earning self-employed income. Log in to myIR and let IRD know you've started a business. No fee, no separate 'business IRD number' — your personal IRD number is your business IRD number as a sole trader. Full sole-trader walkthrough.
- Get an NZBN (optional, free, 5 minutes). A New Zealand Business Number makes you look established and is handy for suppliers and invoices. Not required, but free and worth it. How to get an NZBN.
- Register for GST only if you need to. You must register once your turnover passes — or is expected to pass — NZ$60,000 in any 12-month period. Below that it's optional, and for many home-services operators staying unregistered is actually the smarter call. GST for sole traders, explained.
- Understand your ACC obligations. You don't apply for this — ACC invoices you automatically after your first tax return. But you should know what's coming and consider whether default cover is right for you. ACC for the self-employed.
- Open a separate bank account. Not legally required for a sole trader, but mixing business and personal money is the single biggest bookkeeping headache. A free second transaction account is enough to start.
- Set money aside for tax from dollar one. No employer is doing PAYE for you now. Put 20–30% of every payment into a separate account the day it lands. This is the step that saves people from the first-year trap below.
What each step actually costs
| Step | Cost | Required? |
|---|---|---|
| Become a sole trader | Free | Yes — the default structure |
| Tell IRD via myIR | Free | Yes |
| Get an NZBN | Free | Optional |
| Register for GST | Free to set up | Only if over $60k turnover |
| ACC levies | Invoiced later | Yes — automatic |
| Business bank account | Free to ~$5/month | Recommended |
In other words: you can be a legally-trading sole trader in New Zealand today for $0. The cost of starting a business is the gear and the marketing, not the paperwork.
The trap that catches everyone
The first-year double tax bill
In your first year of self-employment you pay no tax as you go. Then, after you file your first IR3 return, IRD asks for the whole year's tax in a lump — AND provisional tax for the year ahead at the same time. People who didn't set money aside get a bill that's effectively ~1.5× a normal year's tax, all at once. The fix is step 7: bank 20–30% of every payment from day one.
What you can safely ignore at the start
New operators waste weeks on things that don't matter yet. You do not need, on day one: a registered trademark, a limited company, a GST number (unless you're already over the threshold), a fancy accounting suite, a logo designer, or a lawyer. Start trading, get customers, add structure when the business earns it.
If you're coming off a benefit
If you're on Jobseeker Support, Sole Parent Support or Supported Living Payment, there's specific WINZ funding to help you make this transition — up to NZ$21,800+ across three stacking programmes that most case managers don't proactively mention. Sort your sole-trader setup first (it's free and takes minutes), then read the WINZ self-employment funding guide before your case-manager appointment.
Then: decide what you're actually starting
Registration is the easy 10% — the business is the other 90%. If you haven't locked in what service you're offering, the 39 NZ service-business ideas each include realistic startup costs and earnings, and how much you can actually earn in a service business sets honest expectations before you commit.
Common questions
Do I need to register a business name to be self-employed in NZ?
No. As a sole trader you can trade under your own name with zero registration. If you want to trade under a business name (e.g. 'Crystal Clear Cleaning') you can simply start using it — there's no mandatory business-name register for sole traders in NZ, though you can secure the matching .co.nz domain and social handles. Registering a company is the only way to formally reserve a name.
Is there a fee to become a sole trader in New Zealand?
No. Becoming a sole trader is free and effectively instant. You use your existing personal IRD number, tell IRD via myIR that you're now earning self-employed income, and you're trading. The only things that cost money are optional structures (a limited company is ~$160 to incorporate) and the actual business expenses.
When do I have to register for GST?
You must register for GST once your turnover has passed NZ$60,000 in the last 12 months, or you reasonably expect it to pass $60,000 in the next 12 months. Below that threshold registration is voluntary. For many home-services businesses serving private customers, staying under the threshold and not registering keeps you 15% cheaper than GST-registered competitors — see our full GST guide for when voluntary registration does and doesn't make sense.
Do I pay ACC as a self-employed person?
Yes. Everyone earning self-employed income in NZ pays ACC levies. You don't apply — ACC calculates your levy from your first tax return and invoices you, usually well into your second year of trading. Because of this lag, budget for it from the start so the invoice isn't a shock.
How much should I set aside for tax as a sole trader?
A safe default is 20–30% of every payment, banked into a separate account you don't touch. The exact figure depends on your total income and expenses, but new operators who set aside nothing are the ones who get hit hardest by the first-year double bill (the year's tax plus provisional tax, both due at once). When in doubt, set aside more — a refund is a nicer surprise than a shortfall.
