The Australian tax system uses a progressive structure with 5 tax brackets for the 2026-27 financial year. The tax-free threshold of $18,200 means you pay no tax on income below this amount. For FY2026-27, the second bracket drops to 15% (from 16%), saving up to $268/year for those earning above $45,000. The third bracket remains 30% following Stage 3 cuts. All Australian residents also pay a 2% Medicare levy. A $100,000 earner pays $20,520 income tax + $2,000 Medicare = $22,520 total (~22.5%).
