New Zealand Self-Employed Tax Calculator

Find out how much tax you'll need to pay

As a sole trader, it’s often tricky to figure out exactly how much tax you’ll need to set aside to cover your annual tax bill. Most income tax calculators are set up for permanent employees working PAYE jobs, and so aren’t completely accurate for the self-employed.

That’s why we decided to create our own tax calculator, specifically for self-employed freelancers, contractors, and other sole traders. Unlike other PAYE income tax calculators, it lets you take into account any tax deductions you are eligible for, while providing an estimate of how much you’ll owe across the different taxes and levies.

Ready to find out how much tax you’ll need to pay? Plug your numbers into our simple tax calculator below to get the totals 👇

Disclaimer: Please note the tax rates shown above are an estimate based on the figures you’ve provided and don’t take into account factors such as secondary tax obligations. Once Hnry becomes your tax agent, we can factor these in and ensure you’re always taxed at the correct rate. If you have any questions, please reach out to the team.

Key Taxes for the Self-Employed

Income tax

You’re required to pay tax on all your income, whether it comes from a full time job or a self-employed gig. Unlike in other countries, there’s no ‘tax free’ threshold in New Zealand, so you’ll owe income tax from the first dollar you earn.

The IRD calculates your income tax rate by adding up your earnings from all your sources of income (iPAYE/salary jobs, self-employed income, investment income etc) and deducting tax according to our progressive tax rate system.

There’s sometimes confusion around tax codes for secondary income, and the amount of tax owed on self-employed earnings – but rest assured, the income tax rates for salaried earners and self-employed individuals are exactly the same.


If you earn over $60,000 in a 12-month period in just self-employed income (i.e. not including any PAYE income), you’ll be required to register for and charge GST.

What this means is that you’ll need to charge customers an additional 15% GST on top of your regular prices. This 15% is then payable to IRD whenever you file your GST returns.

If you make business purchases, the GST on any business purchase will reduce the amount of the GST you’ve collected that will be payable to IRD.

ACC levies

On top of income tax, you’ll also need to pay ACC levies on your self-employed income. The exact cost of your ACC levies will depend on the type of work you do.

If you also earn income from a PAYE job, then you’ll already be making ACC contributions as part of your PAYE taxes, and any ACC levies on your self-employed income will be in addition to that.

It’s worth noting that there are annual limits for ACC levies, over which you won’t be required to make any further payments.N.B. For our tax calculator, we’ve assumed an average ACC levy rate. But you may need to set aside more, depending on the type of work you do, and the associated risk.

Student loan

If you currently have a student loan, and you’re earning over the annual threshold of $22,828, you’ll be required to make repayments on that loan at the standard IRD rate of 12%.

This applies to your sole trader income – it’s in addition to any repayments you make from a PAYE salary.
