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.
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 Contribution
- 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).
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.

What is the ACC Earner Levy?
A levy of $1.60 per $100 ($1.60%) on earnings up to $139,384, funding ACC (Accident Compensation Corporation) no-fault accident insurance. It is separate from income tax but collected with PAYE. This is particularly important in the context of nz paye calculator calculations, where accuracy directly impacts decision-making.

Understanding the underlying methodology helps users interpret results correctly and identify when additional analysis may be warranted.
How does student loan repayment work through PAYE?
12% of income above the repayment threshold ($22,828 in 2024) is automatically deducted. The deduction continues until the loan is repaid, regardless of how long it takes. This is particularly important in the context of nz paye calculator calculations, where accuracy directly impacts decision-making.

Does KiwiSaver reduce PAYE in New Zealand?
No. Unlike pension contributions in many countries, KiwiSaver contributions do not reduce PAYE or taxable income in New Zealand. This is particularly important in the context of nz paye calculator calculations, where accuracy directly impacts decision-making. Professionals across multiple industries rely on precise nz paye calculator computations to validate assumptions, optimize processes, and ensure compliance with applicable standards. Understanding the underlying methodology helps users interpret results correctly and identify when additional analysis may be warranted.
What is the no-notification PAYE rate?
If an employee does not provide a tax code, the employer must deduct PAYE at 45% (no-notification rate). This is to prevent under-withholding for secondary income. This is particularly important in the context of nz paye calculator calculations, where accuracy directly impacts decision-making. Professionals across multiple industries rely on precise nz paye calculator computations to validate assumptions, optimize processes, and ensure compliance with applicable standards.

Do I get a tax refund in New Zealand?
Inland Revenue performs automatic annual income tax assessments for most salary earners. If you have been over-withheld, a refund is processed automatically — you do not need to file a return. This is particularly important in the context of nz paye calculator calculations, where accuracy directly impacts decision-making. Professionals across multiple industries rely on precise nz paye calculator computations to validate assumptions, optimize processes, and ensure compliance with applicable standards. Understanding the underlying methodology helps users interpret results correctly and identify when additional analysis may be warranted.
When is the NZ tax year?
The New Zealand tax year runs from 1 April to 31 March. PAYE is an ongoing deduction but the annual assessment reconciles the full year from 1 April. This is particularly important in the context of nz paye calculator calculations, where accuracy directly impacts decision-making.

What is the secondary tax code?
If you have more than one employer, the secondary employer applies a secondary tax code (S, SH, ST, or SA depending on secondary income level) to ensure the correct marginal rate is withheld on combined income. This is particularly important in the context of nz paye calculator calculations, where accuracy directly impacts decision-making. Professionals across multiple industries rely on precise nz paye calculator computations to validate assumptions, optimize processes, and ensure compliance with applicable standards. Understanding the underlying methodology helps users interpret results correctly and identify when additional analysis may be warranted.

¿Sabías que?
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.
