Income Breakdown
Day Rate to Annual Salary
Your annual equivalent is calculated by multiplying your day rate by the number of working days per week and weeks per year. The default of 48 weeks accounts for 4 weeks of unpaid leave (contractors do not receive paid leave under the Employment Relations Act 2000).
Comparing with a Permanent Role
When comparing a day rate to a permanent salary, remember that permanent employees receive 4 weeks annual leave, 10 sick days, 11 public holidays, employer KiwiSaver contributions (3%), and other benefits. A common rule of thumb is to add 30-40% to a permanent salary to get the equivalent day rate.
Tax Calculation Method
Tax is calculated using the 2025-26 IRD individual income tax rates (10.5% to 39%), including the Independent Earner Tax Credit (IETC) where applicable. The ACC earner levy is also deducted from your income.
GST Considerations
As a contractor, if your annual turnover exceeds $60,000 you must register for GST. You will charge 15% GST on top of your day rate when invoicing clients. The GST collected is not your income -- it is remitted to IRD.
IRD-Aligned: Uses 2025-26 individual tax rates including IETC and ACC earner levy. This assumes you are a New Zealand tax resident. For complex situations, consult a chartered accountant.
How to set your daily rate as a contractor and what taxes apply
What is a day rate and who uses it?
A day rate is the amount you charge per day of work as a contractor or freelancer. It is common in IT, consulting, construction, and project work in New Zealand. Instead of earning a fixed salary, you invoice your clients for each day worked. A typical day rate in NZ might range from NZ$400 to NZ$1,200 depending on your skills and industry.
How do I convert a salary to a day rate?
Take your desired annual salary, add the cost of benefits you will miss out on (KiwiSaver, annual leave, sick leave, ACC), then divide by the number of billable days per year. Most contractors work about 220 billable days per year. So a NZ$100,000 salary might need a day rate of NZ$600 to NZ$700 once you factor in unpaid leave, admin time, and business costs.
Do I need to charge GST on my day rate?
If your turnover is above NZ$60,000 per year, you must register for GST and add 15% to your invoices. On a NZ$600 day rate, you would charge NZ$690 including GST. The NZ$90 GST is not your income — you collect it and pass it on to IRD. If you are below the NZ$60,000 threshold, GST registration is optional.
What taxes do I pay on my day rate income?
As a sole trader contractor, you pay income tax at standard rates (10.5% to 39%), ACC levies (earner and self-employed levies), and possibly GST. If you earn NZ$150,000 from day rate work, you would pay roughly NZ$37,000 in income tax plus about NZ$2,500 in ACC levies. You may also need to pay provisional tax in advance.
What is provisional tax and do I need to pay it?
Provisional tax is paying your income tax in advance during the year, rather than in one lump sum at the end. You need to pay provisional tax if your tax bill (after PAYE and withholding tax) is more than NZ$5,000. IRD offers three methods: standard (based on last year plus 5%), estimation (your own guess), or the accounting income method (AIM) through compatible software.
What expenses can I deduct from my day rate income?
You can deduct business expenses that are needed to earn your income. Common deductions include: a home office (proportion of rent, power, internet), travel to client sites, professional development, equipment like laptops and phones, accounting fees, and professional indemnity insurance. Keep receipts for everything.
Should I set up a company or stay as a sole trader?
Most contractors start as sole traders because it is simpler and cheaper to set up. However, if your day rate income is above NZ$70,000, a company (paying 28% company tax) might save you money compared to the top personal tax rate of 39%. A company also provides limited liability. Talk to an accountant about your specific situation.
How does KiwiSaver work if I am on a day rate?
As a self-employed contractor, KiwiSaver contributions are voluntary. You do not get employer contributions (3%), but you can still contribute and receive the government contribution of up to NZ$521.43 per year if you put in at least NZ$1,042.86. You can set up voluntary contributions directly with your KiwiSaver provider.
