Going self-employed in New Zealand brings significant tax responsibilities that PAYE employment handles automatically. This guide covers everything a sole trader, freelancer, or gig worker needs to know to stay compliant with IRD.
Set aside 25–28% of every payment received for income tax. Register as a sole trader with IRD. File an IR3 return each year. Register for GST if total income from all sources will exceed $60,000/year. Pay provisional tax in 3 instalments in year 2 onwards. Keep records of business income and expenses.
Step 1: Register as a Sole Trader
Cost: Free
Required: Your IRD number (most NZ residents already have one)
You do not need to formally “register” as a sole trader with a government body — simply begin trading and declare income. However, you should:
- Notify IRD that you have self-employment income — you can do this when filing your first IR3 return or via myIR
- Open a separate business bank account — not legally required but strongly recommended for record-keeping
- Consider registering a business name — at the Companies Office if you want to trade under a name other than your own (not required for sole traders)
If you prefer a company structure (limited liability, separate legal entity), you register a company through the Companies Office (companiesoffice.govt.nz) — but most new gig workers and freelancers start as sole traders.
Step 2: Understand Provisional Tax
This is the most misunderstood part of self-employment tax in NZ.
Year 1: Terminal Tax
In your first year of self-employment, IRD doesn’t collect tax during the year. Instead, you pay it all at year end:
- Tax return due: 7 July following the end of the tax year (31 March)
- If you use a tax agent: up to 7 April of the following year
Example: Income $60,000. Tax owed ~$14,020 (PAYE brackets) + ACC earner levy $1,002. Terminal tax bill: ~$15,022 due in July.
If you haven’t saved for this, it’s a serious problem.
Year 2 Onwards: Provisional Tax
From year 2, IRD requires you to pre-pay estimated tax in three instalments:
| Instalment | Due Date (Standard Year) | Amount |
|---|---|---|
| 1st | 28 August | 1/3 of estimated annual tax |
| 2nd | 15 January | 1/3 of estimated annual tax |
| 3rd | 7 May | 1/3 of estimated annual tax |
IRD calculates your provisional tax based on your prior year’s residual income tax. You can choose to pay based on a different method if you expect income to differ significantly — speak with a tax agent or accountant.
The safe rule: Set aside 25–28% of every payment received. Transfer it to a dedicated savings account immediately. Do not touch it.
Step 3: GST Registration
When is GST Registration Compulsory?
When your total turnover from all sources (including PAYE employment income if relevant) exceeds or is expected to exceed $60,000 in any 12-month period.
Note: GST is assessed on turnover (gross receipts), not profit.
Optional Registration Below $60k
You may register voluntarily below the threshold. Advantages:
- Claim GST back on business purchases (computer, software, office costs, vehicle proportion)
- Appears more professional to corporate clients who prefer GST-registered suppliers
Disadvantage: Quarterly GST returns add administration time.
Filing GST Returns
Most new businesses file 2-monthly or 6-monthly GST returns. Xero, MYOB, or Wave accounting software automates most of the GST calculation.
GST rate in NZ: 15%
ACC Levies for Self-Employed
As a self-employed person, you pay two ACC levies:
| Levy | Who Pays | Rate (2026 indicative) |
|---|---|---|
| Earner levy | All workers, including self-employed | ~1.67% on income up to $142,283 |
| Working cover levy | Self-employed only | Varies by industry risk classification |
ACC sends a working cover invoice once you’re registered as self-employed. The rate depends on your industry classification:
- Office work / consulting: ~$1–$2 per $100 of income
- Physical trades: typically higher
Total ACC cost for self-employed: typically 2–4% of income per year.
You can also choose to increase your working cover (salary continuation in event of injury) above the minimum. ACC’s self-employed cover tool at acc.co.nz calculates your indicative levy.
Deductible Business Expenses
You can deduct legitimate business expenses from your income before calculating tax:
| Expense | Deductible | Notes |
|---|---|---|
| Computer, equipment | Yes (business use %) | If mixed-use, deduct business proportion |
| Phone | Yes (business use %) | Typical business proportion: 50–80% |
| Home office | Yes (floor area %) | Rent/mortgage, power, internet proportioned |
| Vehicle | Yes (business use %) | Keep logbook if mixed personal/business use |
| Software subscriptions | Yes | Accounting, project management, design tools |
| Professional development | Yes | Courses, books relevant to your work |
| Accounting/tax agent fees | Yes | Fully deductible |
| Business insurance | Yes | Professional indemnity, public liability |
| Marketing and advertising | Yes | Website, ads, business cards |
Not deductible: Fines, personal expenses, clothing (unless specific work uniform), private vehicle use.
Tax Rates Applicable to Self-Employed Income
Self-employed income is taxed at the same progressive rates as PAYE employment:
| Income Band | Tax Rate |
|---|---|
| Up to $14,000 | 10.5% |
| $14,001–$48,000 | 17.5% |
| $48,001–$70,000 | 30% |
| $70,001–$180,000 | 33% |
| $180,001+ | 39% |
The rates apply to taxable income = gross income minus allowable deductions.
Accounting Software Options
| Software | Monthly Cost | Best For |
|---|---|---|
| Xero | $30–$80/month | Most NZ businesses; excellent bank feeds |
| MYOB | $29–$69/month | Strong NZ payroll if you hire staff |
| Wave | Free (some paid features) | Freelancers with simple needs |
| Hnry | % of income (~1%) | Handles all tax/GST/ACC automatically |
Hnry is worth noting for NZ freelancers and contractors — it deducts and pays all tax, GST, and ACC from each invoice automatically, eliminating the need to manage provisional tax saving yourself. The fee is approximately 1% of income up to a cap.
