Tax Refund Calculator NZ 2026

Use this New Zealand tax refund calculator to find out whether you are owed a refund from IRD or whether you have tax still to pay. Enter your total gross income for the tax year and the total PAYE tax that was deducted from your pay, and this calculator will work out your correct tax liability, any Independent Earner Tax Credit (IETC) you may be entitled to, and your resulting refund or tax to pay. This is the same calculation IRD performs when it issues your individual tax assessment each year.

Updated April 2026  2026/27 IRD tax brackets, ACC rates, and IETC thresholds applied.
Include all employment income, wages, salary, and any other taxable income. Do not include income from which no PAYE was deducted (declare those separately to IRD).

Find this on your payslips, your employer payment summary, or your MyIR account under "income summary".

Multiple income sources can cause under-deduction of PAYE because each employer taxes only their portion in isolation.

Why might I get a tax refund from IRD?

You may receive a tax refund if your employer deducted more PAYE than your actual tax liability for the year. Common reasons include working part of the year only, having a tax code that was higher than necessary, earning investment income that reduced your effective rate, being entitled to the Independent Earner Tax Credit (IETC) but not having it factored into your PAYE code, or a change in income midway through the year. IRD issues most refunds automatically through the individual tax assessment process that runs from May to July each year.

What is the IETC?

The Independent Earner Tax Credit (IETC) is a tax credit available to individuals earning between $24,000 and $70,000 per year who are not receiving a main benefit such as Jobseeker, Sole Parent Support, or Supported Living Payment. The full credit is $520 per year for incomes between $24,000 and $66,000, tapering to zero by $70,000. If you have the ME tax code, your employer should be factoring this in throughout the year. If not, IRD will include it in your end-of-year assessment.

What if I have tax to pay?

If you had multiple income sources and each employer taxed you at the basic rate on their portion only, your combined income may fall into a higher tax bracket and you could owe tax. Similarly, if you received untaxed income such as rental income, freelance earnings, or interest, you may owe terminal tax. IRD will issue an assessment showing the amount owed, which must be paid by 7 February following the end of the tax year (or 7 April if you have a tax agent).
