About Australia's Tax System
Australia uses a progressive income tax system with a generous tax-free threshold of A$18,200. The Stage 3 tax cuts (effective July 2024) reduced the 32.5% rate to 30% and lowered the 19% rate to 16%, benefiting most middle-income earners.
In addition to income tax, Australians pay the Medicare Levy (2%) to fund the public healthcare system. Those without private health insurance above certain income thresholds also pay the Medicare Levy Surcharge (1–1.5%).
Superannuation is a mandatory employer contribution (11.5% in 2024–25) to retirement savings. While not deducted from your pay, it’s an important part of total compensation.
HECS-HELP repayments are income-contingent – you only repay your university debt once your income exceeds A$54,435.
