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 money aside from every payment received for income tax, because no PAYE is withheld. File an IR3 return each year. Register for GST if your turnover from your taxable activity was at least $60,000 in the last 12 months, or you expect it to be at least $60,000 in the next 12 months. 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 ~$10,221 (PAYE brackets) + ACC earner levy ~$1,050. Terminal tax bill: ~$11,271 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.
Tax is charged on your profit after allowable expenses, and IRD gives no flat percentage to set aside. Moving money into a dedicated savings account as you are paid makes it easier to have the cash ready for each instalment.
Step 3: GST Registration
When is GST Registration Compulsory?
When your turnover from your taxable activity was at least $60,000 in the last 12 months, or you expect it to be at least $60,000 in the next 12 months. Wages from PAYE employment are not part of that turnover.
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 (2026–27) |
|---|---|---|
| Earner levy | All workers, including self-employed | 1.75% on income up to $156,641 |
| ACC Work levy | Businesses, including self-employed | Different for every business |
ACC bases the Work levy on the risk of injury at work, your claims history and your liable income. ACC sends your levy invoice by post or email once you have filed a tax return.
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 $15,600 | 10.5% |
| $15,601–$53,500 | 17.5% |
| $53,501–$78,100 | 30% |
| $78,101–$180,000 | 33% |
| $180,001+ | 39% |
The rates apply to taxable income = gross income minus allowable deductions.
Accounting Software Options
| Software | Cost (from the provider’s own page) |
|---|---|
| Xero | $37 to $135/month excl. GST (Ignite to Ultimate plans) |
| MYOB | $315 to $585/year + GST (Lite and Pro plans) |

| Hnry | 1% + GST of income paid into Hnry, capped at $1,500/year |
Hnry calculates and pays income tax, GST, ACC levies and student loan repayments from income paid into its account, and its accountants file income tax and GST returns. Prices change, so check each provider’s pricing page.
