What is PAYE Calculator (New Zealand)?
▾
The New Zealand PAYE (Pay As You Earn) calculator helps employees and employers estimate the income tax and ACC earner levy withheld from each paycheck. PAYE is the mechanism by which Inland Revenue (IR) collects income tax from salary and wage earners in New Zealand, with employers deducting tax directly from employee pay. New Zealand uses a progressive income tax system with rates for the 2024 tax year: 10.5% on income up to $14,000; 17.5% on income from $14,001 to $48,000; 30% on $48,001 to $70,000; 33% on $70,001 to $180,000; and 39% on income above $180,000. In addition to income tax, PAYE includes the ACC Earner Levy of $1.60 per $100 of earnings (1.60%) on earnings up to $139,384 per annum. Student loan repayments are also deducted via PAYE at 12% on income above the repayment threshold of $22,828 per annum. Employees with secondary employment or extra income can have a secondary tax code applied (no-notification rate of 45% applies if no tax code is provided). New Zealand has no deductible retirement savings from income tax — KiwiSaver contributions do not reduce PAYE. The tax year runs from 1 April to 31 March. Most salaried employees receive an automatic income tax assessment from IR each year — those with straightforward affairs generally neither owe nor receive a significant refund.

Formula
▾
PAYE = Progressive Rate on Gross Income; ACC Levy = min(Gross, $139,384) × 1.60%; Student Loan = max(0, Gross - $22,828) × 12% (if applicable); Total Deduction = PAYE + ACC + Student Loan + KiwiSaver Employee ContributionHow to PAYE Calculator (New Zealand)
▾
- 1Determine the employee's gross annual salary equivalent from pay period earnings.
- 2Apply the progressive income tax bands to calculate annual income tax.
- 3Add ACC Earner Levy of 1.60% on earnings up to $139,384 per annum.
- 4Add student loan deduction if the employee has a student loan — 12% of income above $22,828.
- 5Divide by pay periods (weekly, fortnightly, monthly) to get per-paycheck deductions.
- 6Also deduct KiwiSaver employee contribution (3/4/6/8/10%) — not part of PAYE but typically processed together.
- 7Net pay = Gross - PAYE - ACC - Student Loan - KiwiSaver (employee share).
Worked Examples
▾
Effective income tax rate ~20%
At $70K salary with 3% KiwiSaver, the effective income tax rate is 20%. Adding ACC and KiwiSaver, total deductions are about 24.6% of gross.
39% applies only to income above $180,000
Even at $200K, the effective income tax rate is only 29% due to progressive structure. The 39% rate applies only to the $20,000 above $180,000 — not the whole amount.
Student loan deduction is 12% above $22,828 threshold
The $3,861 student loan repayment is automatic via PAYE. It cannot be reduced — it applies as a flat 12% on income above the threshold until the loan is repaid.
Very low effective rate for low income earners
At $20K the effective income tax rate is just 9.1%. Most low-income earners in NZ pay very modest PAYE, with the 10.5% band protecting the first $14,000.

Frequently Asked Questions
▾
What is PAYE in New Zealand and how does it work?
PAYE, or Pay As You Earn, is a tax withholding system used in New Zealand where employers deduct income tax and ACC earner levy from their employees' salaries or wages. The PAYE system is designed to collect income tax from salary and wage earners, with employers acting as agents for Inland Revenue (IR). For example, if an employee earns $60,000 per year, their employer will withhold a portion of their income tax and pay it to IR on their behalf, using a tax code provided by the employee.
How do I determine my tax code for PAYE purposes?
To determine your tax code, you'll need to consider your income, any student loan repayments, and other factors. The main tax codes are M (main income), ME (main income with student loan), and SB (secondary income with a specified balance date). For instance, if you have a student loan and this is your main source of income, you would likely use the ME tax code, which withholds more tax to account for your student loan repayments.
What is the ACC earner levy and how is it calculated?
The ACC earner levy is a contribution to the Accident Compensation Corporation (ACC), which provides accident insurance for all New Zealanders. The levy is calculated as a percentage of your earnings, with the rate typically ranging from 1.21% to 1.75% of your income, depending on your tax code and other factors. For example, if you earn $50,000 per year and your ACC earner levy rate is 1.21%, you would pay $605 per year in ACC earner levies.
What are some common mistakes to avoid when dealing with PAYE and tax codes?
One common mistake is not updating your tax code when your income or financial situation changes, which can result in over- or under-payment of tax. Another mistake is not taking into account other sources of income, such as investments or secondary jobs, which can affect your tax obligations. To avoid these mistakes, it's essential to regularly review your tax code and income to ensure you're meeting your tax obligations accurately.
Can you provide a real-world example of how PAYE works in New Zealand?
Let's say John earns $70,000 per year, and his employer withholds 25% of his income in PAYE tax, which is $17,500 per year, or $1,458 per month. Additionally, John's employer withholds $845 per year in ACC earner levies, which is 1.21% of his income. At the end of the tax year, John may be entitled to a tax refund if he has overpaid his taxes, or he may need to pay more tax if he has underpaid. This example illustrates how PAYE works in practice to collect income tax and ACC earner levies from employees in New Zealand.
Common Mistakes to Avoid
▾
- !Applying the marginal tax rate to the whole income rather than just the income within each band — 39% only applies to income above $180,000.
- !Forgetting to include the ACC earner levy (1.60%) on top of income tax when computing total payroll deductions.
- !Not using the correct secondary tax code for secondary employment — under-withheld employees face end-of-year tax bills.
- !Assuming KiwiSaver contributions reduce PAYE — they do not in New Zealand.
- !Not updating IR when income changes significantly mid-year, leading to under- or over-withholding.
Pro Tip
Check your IR tax code annually to ensure it reflects your current situation. If you have investment income, rental income, or a side business, update your Estimated Annual Income with IR to avoid a large end-of-year tax bill. IR's myIR online portal makes it straightforward to update your tax code and check your account status throughout the year.
Did you know?
New Zealand introduced PAYE in 1958 — a significant administrative achievement for a country of just 2.3 million people at the time. New Zealand was also one of the first countries to automate income tax assessments — from 2019, most salary and wage earners receive an automatic income tax assessment in May, with refunds paid directly into bank accounts or tax bills issued, completely eliminating the need for most New Zealanders to file an annual tax return.
