How Income Tax Works in Australia
Australia uses five brackets from 0% to 45%, with the first A$18,200 entirely tax-free. The Medicare Levy adds 2% on top of income tax. The Australian system has no state income tax, but the unique feature is mandatory superannuation — employers contribute 12% of salary to a retirement fund (in 2026), separate from take-home pay. From the employee's perspective, take-home pay is only reduced by income tax and Medicare; super is additional employer cost.
Worked example. On an A$75,000 salary, income tax is roughly A$14,442 and Medicare A$1,500 — about A$59,058 take-home, with A$9,000 going into super separately.
What this calculator shows. Move the slider in the calculator above to your gross salary. Every figure — tax owed, effective rate, marginal rate, social contributions, take-home — is computed bracket-by-bracket from the ATO 2025-26 statutory tables. There is no estimation or rounding.
How We Calculate Australia Income Tax
Brackets, thresholds, and contribution rates come directly from ATO 2025-26, published by the Australian Taxation Office (ATO). We do not estimate, smooth, or interpolate.
Income tax is computed bracket-by-bracket on income after the standard deduction. Mandatory social contributions are layered on top, applying statutory caps where they exist.
Single filer, gross employment income, no other deductions or credits. No regional layer applies.
Tables are reviewed annually when each authority publishes its update. See the data methodology page for full citations.
