Estimate Your Australian Tax Refund
Use this quick estimator to work out whether you may get a refund or have tax to pay at year-end.
Assumes Australian resident individual tax rates and gives a general estimate only. This tool does not include HELP/HECS repayments, Medicare Levy Surcharge, private health loading, non-resident rules, or special offsets.
How this income tax refund calculator australia tool works
This calculator estimates your end-of-year tax position based on four key values: your total income, tax already withheld, deductions, and offsets. It then applies resident income tax rates, optional Medicare Levy, and a basic Low Income Tax Offset estimate to show whether you are likely to receive a refund or owe money.
If your employer withheld more tax than your final tax liability, you may receive a refund. If not enough tax was withheld, you may need to pay the difference after lodging your return.
What is included in the estimate
- Australian resident individual tax brackets (simplified current structure)
- Taxable income calculation (income minus deductions)
- Optional Medicare Levy at 2%
- Estimated Low Income Tax Offset (LITO)
- Your entered tax offsets/credits
What is not included
- HELP/HECS repayment obligations
- Medicare Levy Surcharge (MLS) and private health insurance impacts
- Non-resident tax rates
- Business, trust, investment, or capital gains complexity
- Family Tax Benefit or Centrelink interactions
Step-by-step guide to using the calculator
1) Enter your total assessable income
Include salary, wages, bonuses, and other taxable income you expect to report in your tax return. If unsure, check your year-to-date payroll summary and other payment summaries.
2) Enter PAYG withheld tax
This is the total tax your employer has already withheld. You can find it on payslips or your annual income statement.
3) Add deductible expenses
Include valid deductions such as work-related costs, self-education expenses, and charity donations where rules allow. Keep receipts and records.
4) Add any other offsets
Enter offsets you already know apply to your situation. If you are unsure, leave this at 0 and speak to a registered tax agent for personalised advice.
5) Review refund or amount owing
After calculating, the tool displays an estimated tax payable and compares that to tax already withheld.
Example scenarios
Example A: Potential refund
If your employer withholds conservatively and you claim deductions at tax time, your final liability can be lower than tax paid through payroll. That difference often becomes your refund.
Example B: Potential tax bill
If you changed jobs, had extra side income, or used outdated withholding settings, your PAYG may be too low. In that case, you may owe additional tax.
How to improve your refund position legally
- Keep records all year instead of scrambling in June
- Claim only legitimate deductions supported by evidence
- Review withholding settings after salary changes
- Track multiple income streams so withholding is sufficient
- Lodge on time to avoid penalties and delays
Common mistakes to avoid
- Guessing deductions without documentation
- Forgetting interest, dividends, or gig income
- Ignoring Medicare and surcharge impacts
- Assuming every deduction returns dollar-for-dollar cash
