- What are the current Australian tax brackets?
- For 2026-27 (residents): $0-$18,200 = 0%, $18,201-$45,000 = 15%, $45,001-$135,000 = 30%, $135,001-$190,000 = 37%, $190,001+ = 45%. The 15% rate (down from 16%) took effect 1 July 2026 and drops again to 14% from 1 July 2027.
- What's the difference between marginal and effective tax rate?
- Your marginal rate is the tax rate on your last dollar earned (determines the bracket you're in). Your effective rate is total tax divided by total income: the average rate across all brackets. Someone earning $100,000 in 2026-27 has a 30% marginal rate but pays about 20.5% of income in tax (22.5% with the Medicare levy).
- How do tax deductions work?
- Deductions reduce your taxable income, not your tax dollar-for-dollar. A $1,000 deduction saves you $1,000 × your marginal rate. At the 30% bracket, a $1,000 deduction saves $300 in tax (plus $20 of Medicare levy).
