Setting Up as a Sole Trader in NZ: Tax, ACC, and Insurance Guide

Starting out as a sole trader in New Zealand is relatively simple from a legal and administrative standpoint. But understanding the tax, ACC, and insurance landscape upfront will save you significant headaches later. This guide covers the practical steps and financial obligations of becoming self-employed in NZ.

What Makes You a Sole Trader?

In New Zealand, you become a sole trader the moment you start earning income from self-employment. There's no formal registration required — you don't need to register a company, file formation documents, or pay any establishment fee. Your business and you are legally the same entity.

This simplicity is both an advantage and a risk. The advantage: you can start earning immediately with minimal bureaucracy. The risk: you are personally liable for everything — debts, legal claims, and any obligations your business incurs.

Step 1: IRD Registration and Tax

Get an IRD number: If you don't already have one (most NZ residents do), apply at IRD.govt.nz. You'll need your IRD number to file tax returns and pay ACC levies.

Register your income with IRD: As a sole trader, you file an Individual income tax return (IR3) annually, including your self-employed income. If you're GST registered, you'll also file GST returns (monthly, 2-monthly, or 6-monthly).

GST registration: Register for GST if your annual turnover exceeds $60,000 (or is expected to). Registration is optional below this threshold but can be advantageous. Once registered, you charge GST on your invoices and claim back GST on business expenses.

Provisional tax: Once you earn self-employment income, IRD will calculate a provisional tax obligation for the following year based on your previous year's income. Provisional tax is paid in installments through the year. Budget for this — it can catch new sole traders off guard.

Tax deductible expenses: As a sole trader, business expenses are deductible from your income before tax. Common deductible expenses include: - Business insurance premiums - Vehicle costs (mileage or actual costs for business use) - Tools and equipment (or depreciation) - Phone and internet (business use proportion) - Home office costs (business use proportion) - Accounting fees - Professional development

Keep records of all business income and expenses. Your accountant can help maximise legitimate deductions.

Step 2: ACC — What You'll Pay

ACC covers personal injury from accidents in NZ. As a sole trader, you pay ACC levies based on your earnings. The levy structure for self-employed people:

Working safer levy: A small flat levy collected by IRD.

Work levy: Based on your occupation risk category and your income. Your trade or profession is classified into a risk category by ACC, and the levy rate reflects how hazardous that work is historically.

Earners' levy: A flat rate on your income, like the earners' levy paid by employees.

ACC sends you a levy invoice each year based on your previous year's income. The first year as a sole trader, you'll often pay a minimum levy as ACC doesn't yet know your income.

What you get from ACC: - Medical treatment for accident injuries (with some out-of-pocket costs) - Weekly compensation at 80% of pre-injury earnings (up to an annual cap) if accident injuries stop you working - Rehabilitation support

What ACC does NOT cover: Any illness or condition not caused by an accident. This is the gap that income protection insurance fills.

Step 3: Essential Insurance for New Sole Traders

Insurance is the most underappreciated element of setting up as a sole trader. The cost is real and ongoing; the benefit only materialises when something goes wrong. But the consequences of being uninsured when something does go wrong can be catastrophic.

Start with these policies:

Public liability: If you interact with clients, work at client premises, or have any business-related contact with third parties, public liability is essential. For a new sole trader, this is often the first insurance policy to get. Cost: from ~$300/year.

Professional indemnity (if you provide advice or professional services): PI insurance protects you against claims arising from errors or negligence in your advice or work. Essential for consultants, IT professionals, health practitioners, accountants, and many others. Cost: from ~$600/year.

Income protection: Before ACC, before business insurance — income protection may be the most important policy for a sole trader. If illness stops you working, nothing else matters if you can't pay your mortgage. Cost: varies significantly by age and occupation.

Tools and equipment (if you have a significant tool investment): For tradies and other roles requiring expensive equipment, tools insurance is essential. Cost: from ~$200/year.

Step 4: Business Banking and Record-Keeping

Open a dedicated business bank account: Keep your business and personal finances separate from day one. This makes tax filing simpler, helps you manage cash flow, and creates a clear record of business income and expenses.

Accounting software: Consider cloud-based software such as Xero, MYOB, or QuickBooks from the start. These tools automate much of your bookkeeping, simplify GST returns, and make year-end tax much easier.

Invoice tracking: Maintain clear records of all invoices issued and payments received. Late payers are a common problem for new sole traders — a clear invoicing system helps you follow up promptly.

What to Do First

1. Register for GST if you'll exceed $60k turnover 2. Open a business bank account 3. Set up basic accounting software 4. Get public liability insurance (and PI if relevant) 5. Set up provisional tax payments with IRD 6. Explore income protection insurance

Starting with these fundamentals puts you in a strong position. Build from there as your business grows.
