Overview
PAYG income tax with Medicare levy
Income tax is Australia's largest revenue source. Resident individuals pay marginal rates from 0% to 45% on taxable income, plus 2% Medicare levy. Foreign residents start at 30% with no tax-free threshold.
Taxable income = assessable income − allowable deductions. Deductions are the easiest legal win — work-from-home, vehicle, professional memberships, education and tools all add up.
