Australian Tax Brackets 2024-25
The Australian Taxation Office (ATO) uses a progressive tax system with the following brackets for residents:
Tax Rates for 2024-25:

- 45% on income over $180,000
Example Calculation
Annual income: $85,000
- $0 - $18,200: $0 (tax-free)
- $18,201 - $45,000: $5,092 (19%)
- $45,001 - $85,000: $13,000 (32.5%)
- Total income tax: $18,092
Medicare Levy
In addition to income tax, most Australian residents pay the Medicare Levy of 2% of taxable income.
For $85,000 income:

Tax Planning Strategies
1. Maximize Super Contributions
Strategy: Salary sacrifice to super
- Reduces taxable income
- Super taxed at only 15%
- Builds retirement savings
Example: Earning $120,000
- Sacrifice $10,000 to super
- Tax saving: $10,000 × (37% - 15%) = $2,200
2. Claim All Deductions
Keep records of:
- Work-related expenses
- Charitable donations
- Tax agent fees
- Investment expenses
Tip: Use the ATO's myDeductions tool in the ATO app.
3. Time Your Income
If possible, defer income to the next financial year or bring forward deductions to reduce current year tax.
4. Spouse Contributions
If your spouse earns less than $40,000, contributing to their super can earn you a tax offset of up to $540.
5. Private Health Insurance
Avoid Medicare Levy Surcharge by maintaining appropriate private health cover if you're a high-income earner.
