When to use this calculator
- Before accepting a pay change, bonus, pension contribution, or salary-sacrifice option.
- When you want to compare employed, self-employed, or dividend-based income scenarios.
- When you need a simple take-home estimate before running payroll or filing returns.
- When you are approaching the £100,000 income level and want to understand the personal allowance taper effect.
- When you are planning a salary sacrifice arrangement and need to see the net pay impact before agreeing terms.
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.
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 — each metric tells a different part of the story. Then rerun the tool with one input adjusted to see which variable has the biggest effect on all three outputs before you settle on a plan.
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 or a recommendation to make a tax decision.
ACC Levy
Use this metric to compare scenarios side by side and understand how changes in the key inputs drive the final outcome. If the figure surprises you, isolate one variable at a time and rerun the calculation to identify which assumption is responsible.
KiwiSaver
Use this metric to compare scenarios side by side and understand how changes in the key inputs drive the final outcome. If the figure surprises you, isolate one variable at a time and rerun the calculation to identify which assumption is responsible.
Total Deductions
This is the headline outcome of the calculation, but it is most useful when read alongside the supporting metrics below it rather than in isolation. Try changing one input at a time and watching how this total moves to understand which driver has the biggest impact.
Take-Home
Use this metric to compare scenarios side by side and understand how changes in the key inputs drive the final outcome. If the figure surprises you, isolate one variable at a time and rerun the calculation to identify which assumption is responsible.
Monthly
Use this metric to compare scenarios side by side and understand how changes in the key inputs drive the final outcome. If the figure surprises you, isolate one variable at a time and rerun the calculation to identify which assumption is responsible.
Effective Rate
The effective rate lets you compare options on a true like-for-like basis rather than being misled by different compounding periods or fee structures. Use it to cut through headline marketing rates when shortlisting providers or products.
Method & assumptionsAuthoritative sources
This calculator applies the 2024/25 IRD personal income tax brackets and the ACC Earner Levy rate of 1.60% (capped at NZ$139,384 of liable earnings) to give New Zealand employees a clear picture of their after-tax position. The five progressive tax bands — 10.5%, 17.5%, 30%, 33%, and 39% — mean only the income within each bracket is taxed at that rate. The effective rate shown combines income tax and ACC levy as a proportion of gross income, giving a single figure for easy comparison. KiwiSaver contributions are shown separately as they are savings rather than tax, though they do reduce your net pay. All figures are based on annual employment income with no other income sources assumed.
New Zealand's tax year runs from 1 April to 31 March, and IRD automatically squares off PAYE for most wage and salary earners through its income tax assessment process. If you have significant income from other sources — such as self-employment, rental property, or overseas investments — your situation may differ from the figures here. Similarly, entitlements such as the Independent Earner Tax Credit (IETC) or Working for Families tax credits are not included in this calculation. For a comprehensive assessment of your obligations or entitlements, use myIR on the IRD website or consult a registered tax agent.
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.
- !Forgetting location-specific taxes, fees, eligibility rules or payroll deductions where they apply.
- !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.
- Use the result to prepare better questions for a lender, provider, adviser or employer rather than treating it as a final answer.
