When to use this calculator
- Before accepting a pay change, bonus or contribution arrangement.

- When you need to convert between hourly, monthly and annual pay.
- When you want to compare two pay scenarios using the same assumptions.
A realistic New Zealand planning example
Use these sample inputs as a quick scenario test, then change one variable at a time to compare outcomes.
| Input | Value |
|---|---|
| Annual Taxable Income (NZ$) | NZ$70,000 |
| Include ACC Earner Levy? | Yes (recommended) |
| KiwiSaver Employee Rate | Not enrolled |
After entering these figures, review income tax, acc levy and kiwisaver together rather than in isolation. Then rerun the tool with one input adjusted.
How to read your results
Income Tax
Review this figure alongside gross income and the local tax rules that apply to you. It is a planning estimate, not a filing result.
ACC Levy
The figure produced by this output for the inputs you entered. Change one variable at a time if you want to see what drives it.
KiwiSaver
The figure produced by this output for the inputs you entered. Change one variable at a time if you want to see what drives it.
Total Deductions
The headline outcome of this calculation. It is most useful when read alongside the supporting metrics rather than in isolation.
Take-Home
The figure produced by this output for the inputs you entered. Change one variable at a time if you want to see what drives it.
Monthly
The figure produced by this output for the inputs you entered. Change one variable at a time if you want to see what drives it.
Effective Rate
The effective rate lets you compare options on a like-for-like basis rather than being misled by different compounding periods or fee structures.
Method & assumptionsAuthoritative sources
This calculator applies the IRD personal income tax bands for the current New Zealand tax year (1 April to 31 March) and the ACC earners’ levy to annual employment income, giving a clear picture of your after-tax position. New Zealand income tax is progressive: the five bands — 10.5%, 17.5%, 30%, 33% and 39% — each apply only to the slice of income inside that band, so nothing is taxed at the top rate unless your income actually reaches it. The effective rate shown combines income tax and the ACC levy as a proportion of gross income. KiwiSaver is shown separately because it is savings rather than tax, though it does reduce your net pay. The exact thresholds, levy rate and maximum liable earnings used here are rendered from IRD data in the guidance section below.
New Zealand’s tax year runs from 1 April to 31 March, and for most salary and wage earners PAYE collected through the year squares off automatically in IRD’s year-end assessment. PAYE is not only income tax: your employer also collects the ACC earners’ levy through the same payroll deduction, and KiwiSaver and student-loan deductions ride on the same system. Figures assume annual employment income with no other income sources; this estimate is not a substitute for a personal tax return.
Common mistakes
- !Using an assumption that is not supported by a current local quote, bill, statement or official source.
- !Treating a generic estimate as a lender, provider, payroll or tax authority decision.
- !Mixing monthly and annual inputs without converting them consistently.
- !Testing only one scenario instead of checking how a cautious assumption changes the result.
What to do next
- Run a second scenario with a cautious assumption so you can see the downside clearly.
- Compare the result with the related calculators below before making a decision.
- Check current local rules, eligibility and provider terms before applying or committing money.
- Keep a record of the assumptions so you can update the estimate when a quote, bill or pay figure changes.
New Zealand income tax and the ACC earners’ levy — how this estimate works
Guidance reviewed 2 September 2026New Zealand collects income tax through PAYE on a marginal schedule set by IRD: each band rate applies only to the slice of annual income inside that band, so your whole income is never taxed at your top rate. Alongside income tax, nearly every employee pays the ACC earners’ levy — collected by your employer through the same PAYE deduction — which funds New Zealand’s no-fault accident cover.
This calculator applies the current IRD bands to the annual taxable income you enter, adds the ACC earners’ levy up to its annual earnings cap, and shows KiwiSaver separately at whatever employee rate you select. The PAYE total here therefore means income tax plus the ACC levy — not income tax alone.
| Income tax bands (2026/27) | 10.5%: $0 to $15,600; 17.5%: $15,600 to $53,500; 30%: $53,500 to $78,100; 33%: $78,100 to $180,000; 39%: $180,000 to above |
|---|---|
| ACC earners’ levy (2026/27) | 1.75% of liable earnings up to $156,641 (maximum $2,741.22) |
| KiwiSaver employee rates | 3.5%, 4%, 6%, 8%, 10% — default 3.5% from 1 April 2026; deducted from net pay, not from taxable income |
Worked example (illustrative figures only)
- Inputs:
- Annual income NZ$80,000 · ACC levy included · KiwiSaver not selected
- Estimate:
- Income tax $16,277.50 + ACC levy $1,400.00 = $17,677.50 total deductions; take-home $62,322.50 (≈ $5,193.54/month); effective rate 22.1%
- What it means:
- The ACC line is a flat levy, not a bracket: at $80,000 it is simply 1.75% of liable earnings, and it stops growing once earnings pass the cap. Income tax is marginal — only the slice above the fourth band threshold reaches the 33% band, which is why the 22.1% effective rate sits well below the 33% marginal rate on your next dollar.
- What is excluded:
- Student-loan repayments, Working for Families, the independent earner tax credit and secondary-income tax codes are not modelled on this page. The NZ Paycheck Calculator adds student loans to the same PAYE stack.
Example values only — not financial advice.
Assumptions
- Taxable income is the annual employment income you enter, with no other income sources.
- Income tax uses the IRD bands from the structured policy layer (10.5%: $0 to $15,600; 17.5%: $15,600 to $53,500; 30%: $53,500 to $78,100; 33%: $78,100 to $180,000; 39%: $180,000 to above).
- The ACC earners’ levy is a flat 1.75% on liable earnings up to $156,641 — collected through PAYE, capped, and not a marginal bracket.
- KiwiSaver is deducted only if you select a rate, and reduces take-home pay rather than taxable income (employee KiwiSaver contributions are not tax-deductible in New Zealand).
Not included
- Student-loan repayments are not part of this page — use the NZ Paycheck Calculator (student-loan toggle) or the student-loan calculators.
- Tax credits are not applied: the independent earner tax credit (up to $520 a year for $24,000–$70,000 incomes) and Working for Families payments would change the final position.
- Secondary income uses SB, S, SH, ST or SA tax codes at different rates — this page assumes one main-income (M code) source.
- Self-employed people pay provisional tax rather than PAYE; business income is not modelled.
- The result is an annual estimate; payroll deducts per pay period with its own rounding, and IRD’s year-end assessment squares off most salary earners automatically.
Reading the result
- Compare the effective rate with your marginal rate: a pay rise near a band boundary is taxed only on the slice above the boundary.
- Once income passes the ACC cap, the levy line stops increasing — extra income attracts income tax only.
- If your year-end assessment differs, check for credits, secondary income or a student-loan repayment that this page does not model.
