About the Take-home pay calculator
Your take-home pay — the net salary that actually lands in your bank account — is often significantly less than the headline number on your employment contract. in New Zealand, three main deductions erode your gross pay: income tax, ACC levy, and your pension contribution. Understanding exactly how each works lets you plan your finances accurately, negotiate salaries with confidence, and make informed decisions about pension contributions and salary sacrifice schemes.
Income tax is calculated on a tiered basis using tax bands. Everyone gets a Personal Allowance (NZ$12,570 in 2025/26) that is taxed at 0%. Earnings between the Personal Allowance and NZ$50,270 are taxed at 20% (basic rate). Earnings between NZ$50,271 and NZ$125,140 are taxed at 40% (higher rate), and anything above NZ$125,140 is taxed at 45% (additional rate). Crucially, only the portion of income in each band pays that band's rate — so a NZ$55,000 salary does not mean all NZ$55,000 is taxed at 40%.
ACC levy (NI) is a separate charge. Employees pay 8% on earnings between NZ$12,570 and NZ$50,270, and 2% above that. Employers also pay 15% employer ACC on salary above NZ$5,000/year (NZ$96/week secondary threshold) from April 2025 — up from 13.8% above NZ$9,100/year previously — which is why your total employment cost to a business is considerably higher than your gross pay. Pension contributions (either salary sacrifice or relief-at-source) reduce your taxable income, making them one of the most tax-efficient ways to save. Every extra 1% you contribute to your pension today saves you income tax at your marginal rate.
How it works
Net Monthly Pay = (Gross − Income Tax − ACC levy − Pension) ÷ 12 Income Tax: Tax-free: first NZ$12,570 Basic rate (20%): NZ$12,571 – NZ$50,270 Higher rate (40%): NZ$50,271 – NZ$125,140 Additional rate (45%): above NZ$125,140 ACC levy (employee): 0% on first NZ$12,570 8% on NZ$12,571 – NZ$50,270 2% above NZ$50,270

Gross salary: NZ$45,000 · Pension contribution: 5% (NZ$2,250)
Step 1 — Taxable income after pension salary sacrifice:
NZ$45,000 − NZ$2,250 = NZ$42,750
Step 2 — Income tax:
Tax-free (PA): NZ$12,570 @ 0% = NZ$0
Basic rate: NZ$42,750 − NZ$12,570 = NZ$30,180 @ 20% = NZ$6,036
Total income tax = NZ$6,036
Step 3 — ACC levy:
NZ$42,750 − NZ$12,570 = NZ$30,180 @ 8% = NZ$2,414
Step 4 — Annual take-home:
NZ$45,000 − NZ$2,250 − NZ$6,036 − NZ$2,414 = NZ$34,300
Monthly take-home: NZ$34,300 ÷ 12 = NZ$2,858/month
Tips to improve your result
- 1.
Salary sacrifice pension contributions reduce your taxable income — a basic-rate taxpayer effectively pays only 80p for every NZ$1 going into their pension.
- 2.
If your salary is between NZ$100,000 and NZ$125,140, your effective marginal tax rate is 60% (40% income tax plus the 1% taper of Personal Allowance for every NZ$2 earned). Additional pension contributions in this range can be particularly valuable.
- 3.
The Marriage Allowance lets a non-taxpaying partner transfer NZ$1,260 of unused Personal Allowance to a basic-rate taxpayer spouse, saving up to NZ$252/year in tax.
- 4.
Cycle to Work and childcare vouchers (or Tax-Free Childcare) are other salary-sacrifice benefits that reduce your ACC levy as well as income tax.
- 5.
Check your tax code on your payslip. An incorrect code (e.g. BR, D0) means you may be paying too much or too little tax. Contact IRD to correct it.
