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 Australia planning example

Use these sample inputs as a quick scenario test, then change one variable at a time to compare outcomes.

Gross Income (A$)

A$80,000

Tax Already Withheld (A$)

18000

Work-Related Expenses (A$)

500

After entering these figures, review refund / (amount owed), income tax and medicare levy 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

Refund / (Amount Owed)

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.

Income Tax

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.

Medicare 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.

Low Income Offset

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 estimates your Australian tax return outcome for 2024/25 using the ATO's income tax brackets, the Low Income Tax Offset (LITO), and the 2% Medicare Levy. Taxable income is calculated by subtracting allowable work-related expenses from gross income — the actual ATO process also allows deductions for charitable donations, self-education expenses, investment costs, and several other categories not modelled here. The Low Income Offset reduces tax payable by up to $700 for incomes up to $37,500, phasing out progressively to zero at $66,667. The Medicare Levy of 2% is applied on total gross income (with a low-income exemption under $26,000). The refund or amount owed is the difference between PAYG tax withheld by your employer and your actual calculated tax liability. Note that the calculator does not model the Low and Middle Income Tax Offset (which ended in 2021/22), private health insurance rebates, or the Medicare Levy Surcharge for uninsured high earners.

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.

Frequently asked

Your refund is the difference between the tax your employer withheld during the year (PAYG) and your actual tax liability calculated at year end. If more was withheld than owed — common when allowable deductions reduce taxable income — you receive a refund. If less was withheld, you owe the balance to the ATO.
