The Stage 3 tax cuts that came into effect in July 2024 restructured Australian tax brackets — reducing the 19% rate, cutting the 32.5% bracket, and eliminating the 37% bracket for income between $120,001–$180,000. Understanding the new structure helps with planning.

Plus Medicare Levy of 2% on most taxable income.

The Medicare Levy Surcharge (MLS)

Singles earning above $93,000 (couples $186,000) without private hospital cover pay an additional 1-1.5% Medicare Levy Surcharge. For many in this income range, private hospital cover (from ~$1,500-2,500/year) is cheaper than the MLS.

Key tax deductions for Australian employees

  • Work-related expenses: Tools, equipment, uniforms (not conventional clothing), training directly related to your current job
  • Home office expenses: The ATO fixed rate (67c/hour worked from home in 2026) or actual cost method
  • Vehicle expenses: If you use your car for work (not commuting), cents per km (88c/km in 2026) or logbook method
  • Self-education: Courses directly related to improving skills for your current job (not a career change)
  • Donations: To DGR (Deductible Gift Recipients) charities — fully deductible
  • Income protection insurance premiums (if paid outside super)
💡 The myTax return: most Australians leave money on the table The ATO pre-fills most income data in myTax, but deductions are your responsibility to add. A survey by H&R Block found Australians collectively leave hundreds of millions unclaimed annually. The most common missed deductions: home office costs, union fees, professional memberships, and car expenses.
