Sole Trader vs Limited Company in New Zealand: 2026 Guide
Thousands of New Zealanders ask this question every year: sole trader or limited company? This guide explains the real differences in tax, liability, ACC levies, and ongoing costs to help you make the right decision.
Sole Trader vs Limited Company in New Zealand (2026)
One of the most common questions from new NZ business owners is whether to operate as a sole trader or register a limited liability company. Both structures are legitimate and widely used, but they have significant differences in tax treatment, personal liability, administrative burden, and perception by clients and suppliers.
What Is a Sole Trader?
A sole trader is an individual who operates a business in their own name (or under a registered trading name). There is no separate legal entity. You and your business are legally the same person. Income is taxed at your personal income tax rate. Expenses are deducted from your business income on your personal tax return.
Setup cost: Zero to minimal. No NZCO registration required. A business name can optionally be registered with NZCO for NZ$42. You do need an IRD number if you do not already have one.
What Is a Limited Company?
A limited company (Ltd) is a separate legal entity registered with the New Zealand Companies Office. It has its own IRD number, can enter contracts, own assets, and employ staff. Shareholders own the company; directors manage it. Company income is taxed at 28% corporate rate. Profits are distributed to shareholders as dividends.
Setup cost: NZ$127.82 to register online. Annual return fee: NZ$45.74. You will also need to maintain annual financial statements and an IRD return for the company.
The Key Differences
| Factor | Sole Trader | Limited Company |
|---|---|---|
| Personal liability | Unlimited (your personal assets at risk) | Limited to share capital (personal assets protected) |
| Tax rate | Personal rate (10.5% - 39%) | 28% company rate + dividend tax on withdrawals |
| ACC levies | Self-employed levy on business income | Employer levy + employee levy if paying salary |
| Credibility | Some clients prefer Ltd companies | Seen as more established and professional |
| Administration | Low (personal tax return only) | Higher (company return, annual return, minutes) |
| Privacy | No public register | Director names and address on public register |
When a Limited Company Makes Sense
Consider registering a company if you:
- Have significant personal assets you want to protect from business liabilities
- Expect to earn more than NZ$70,000-80,000 in net profit (where the company tax rate becomes more efficient)
- Work with contracts that require a company (some government or large corporate contracts)
- Plan to bring in investors or partners in the future
- Want to sell the business eventually (selling shares in a company is cleaner than selling a sole tradership)
- Operate in an industry with significant liability risk (construction, professional advice, food service)
When Sole Trader Is Fine
Staying as a sole trader is fine if you:
- Are just starting out and want minimal complexity and cost
- Have low liability risk (freelance writing, consulting with contracts)
- Earn under NZ$70,000 in profit and are below the 30% personal tax threshold
- Want to test a business idea before committing to a company structure
The ACC Difference
ACC levies are often misunderstood in the sole trader vs company debate. As a sole trader, you pay the self-employed levy (approximately 1.39% of liable earnings in 2024/25) plus ACC earner levy (1.33%). As an employee of your own company, the company pays the employer ACC levy (approximately 0.63% in 2024/25) and you pay the earner levy on your salary. The total can differ significantly depending on your industry classification.
