Rates & sources
UK tax rates and thresholds, as published by HMRC. Scotland and Wales have devolved rates for income tax and property transactions.
Source: HMRC — Tax rates — figures refreshed at the start of each tax year.
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 Gross Salary (NZ$)
NZ$70,000
Pay Frequency
Fortnightly (26/yr)
KiwiSaver Rate
Not enrolled
Student Loan?
No
After entering these figures, review take-home per pay period, gross per period and tax+acc per period 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
Take-Home per Pay Period
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.
Gross per Period
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.
Tax+ACC per Period
Review this figure alongside your gross income so you can understand the true cost of deductions and plan around any thresholds before the tax year closes. If the figure looks higher than expected, check whether any pension or gift-aid contributions could reduce your taxable income.
Annual 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.
Annual Student Loan
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.
Method & assumptionsAuthoritative sources
This calculator divides your annual New Zealand salary into per-period take-home pay after applying all standard PAYE deductions. Income tax is calculated using the 2024/25 IRD brackets, and the ACC Earner Levy of 1.60% is applied up to the maximum liable income of NZ$139,384 per year. Student loan repayments are deducted at 12% on annual income above NZ$22,828, consistent with the current IRD repayment threshold. KiwiSaver contributions reduce your net pay but represent savings credited directly to your retirement fund, supplemented by at least 3% from your employer. The annual net is then divided by 52, 26, 13, or 12 to match your pay frequency.
The figures produced here are estimates based on employment income only and assume a standard M (primary income) tax code. They do not account for Working for Families entitlements, the Independent Earner Tax Credit, secondary income from other sources, or employer-specific arrangements such as salary sacrifice schemes. For a definitive breakdown of your deductions, refer to your payslip or log in to myIR on the IRD website. If you believe your tax code is wrong or your deductions seem incorrect, contact IRD directly or consult a tax professional registered with the New Zealand Institute of Chartered Accountants (NZICA).
Common mistakes
- !Entering gross income when you really want take-home pay, or vice versa.
- !Ignoring pension contributions, deductions, or local tax rules that change the result.
- !Comparing monthly and annual figures without standardising them first.
- !Overlooking the National Insurance threshold changes that apply mid-year when rates or bands are adjusted in a Budget.
- !Assuming a salary sacrifice benefit reduces take-home pay by the full gross amount, rather than only the after-tax cost.
What to do next
- Check the same scenario with related pay or deduction calculators to see the full picture.
- Keep a copy of the assumptions you used so you can compare next tax year or pay period accurately.
- Read the related guides below if you are choosing between multiple income or deduction options.
- If you are self-employed, run the self-employment tax calculator alongside this result to compare the net position against employed income.
- Check whether increasing your pension contribution by even one or two percent changes the take-home significantly — use the pension calculator next.
