Income Tax in Australia — 2026 Guide
Key insight: Medicare Levy + Superannuation sits on top of income tax and isn't optional: Most residents pay an additional 2% Medicare Levy on top of income tax. Separately, employers must also pay compulsory Superannuation Guarantee contributions (11.5%+ of salary) into a retirement fund — this is not deducted from take-home pay. Most people underestimate their total deduction by focusing on income tax alone.
Australia uses a progressive income tax system, with marginal rates rising from the lowest bracket up to a top rate of 45%.

How income tax works here
Most residents of Australia pay tax on income earned during the 2026 tax year. Employers typically withhold tax throughout the year, with a final reconciliation filed after the year ends. Self-employed individuals and those with additional income sources usually need to file a return directly with the tax authority.

Who has to pay it: residency rules
Residency for tax purposes uses the 'resides' test plus several statutory tests (183-day test, domicile test, superannuation test) — it is broader than simply counting days in the country.
Payroll and social contributions
Most residents pay an additional 2% Medicare Levy on top of income tax. Separately, employers must also pay compulsory Superannuation Guarantee contributions (11.5%+ of salary) into a retirement fund — this is not deducted from take-home pay. This calculator's estimate covers income tax only — budget separately for Medicare Levy + Superannuation.
Common mistake to avoid
Forgetting the 2% Medicare Levy when estimating total tax — it is calculated separately from, and on top of, the income tax brackets.
Important note on accuracy
