Estimate your Australian income tax
Use this quick calculator to estimate annual income tax based on ATO-style progressive rates. Great for budgeting, salary planning, and comparing scenarios.
Note: This is an estimate only. It does not include all offsets, HELP/HECS repayments, private health loading, or special circumstances.
How this Australian taxation office tax calculator works
This calculator uses progressive income tax rates and lets you estimate your tax from three core inputs: your gross annual income, deductible expenses, and residency status. It then calculates your taxable income and applies tax brackets to estimate the total tax payable.
For residents, you can optionally include a simple 2% Medicare levy. For foreign residents, Medicare levy is not applied in this tool.
Tax calculation steps
- Step 1: Work out taxable income = gross income − deductions.
- Step 2: Apply progressive tax rates to taxable income.
- Step 3: Add Medicare levy (if selected and resident).
- Step 4: Estimate take-home income annually, monthly, fortnightly, and weekly.

Why taxable income matters more than gross income
A common mistake is budgeting based on gross income. In reality, your tax is calculated on taxable income, which can be lower than gross income after eligible deductions. If you track deductible expenses properly, your effective tax rate can improve and your net cash flow can increase.
Examples of common deductions
- Work-related expenses (where substantiation rules are met)
- Self-education expenses linked to current employment
- Tax agent fees
- Charitable donations to eligible deductible gift recipients (DGRs)
- Investment-related expenses
