Tax planning isn't just about minimising what you owe - it's about maximising what you keep. With proper planning and understanding of Australian tax laws, you can legally reduce your tax burden while building long-term wealth. Here are the essential strategies every Australian taxpayer should know.

Understanding the Australian Tax System
Australia operates a progressive tax system where higher income levels attract higher tax rates. Understanding how this works is fundamental to effective tax planning.
2024-25 Individual Tax Rates (Residents):
| Taxable Income | Tax Rate | Tax on Income |
|---|---|---|
| $0 - $18,200 | 0% | Nil |
| $18,201 - $45,000 | 19% | 19c for each $1 over $18,200 |
| $45,001 - $135,000 | 32.5% | $5,092 + 32.5c for each $1 over $45,000 |
| $135,001 - $190,000 | 37% | $34,317 + 37c for each $1 over $135,000 |
| $190,001+ | 45% | $54,667 + 45c for each $1 over $190,000 |
Plus Medicare Levy: 2% of taxable income (with exemptions and reductions for low-income earners)
Maximising Tax Deductions
Deductions reduce your taxable income, effectively giving you a tax refund at your marginal tax rate. The key is understanding what you can legitimately claim.
Work-Related Expenses:
Car Expenses
Logbook Method: Keep detailed records for 12 weeks, claim actual percentage
Cents per km: Up to 5,000km at 78c per km (2024-25)
Home Office Expenses
Fixed Rate: 67c per hour (2024-25)
Actual Cost: Portion of utilities, depreciation, phone, internet based on work use
Clothing & Uniforms
Compulsory uniforms, protective clothing, occupation-specific clothing. Normal business attire is NOT deductible.
Self-Education
Courses that relate to your current work or are likely to increase income in your current employment.
Other Deductible Expenses:
- Equipment & Tools: Laptops, phones, professional tools
- Travel: Work-related travel (not home to work)
- Professional Materials: Journals, reference books, subscriptions
- Union & Professional Fees: Membership fees, professional registrations
- Gifts & Donations: Deductible gift recipients (DGRs) over $2
Record Keeping Requirements:
- Receipts for all expenses over $300
- Logbooks for car and home office expenses
- Diary entries for small expenses under $300
- Bank statements showing expense payments
- Records must be kept for 5 years
Capital Gains Tax Strategies
Capital Gains Tax (CGT) applies when you sell assets for more than you paid. Smart planning can significantly reduce your CGT liability.
Key CGT Strategies:
50% CGT Discount
Hold assets for more than 12 months to receive 50% discount on capital gains. This can halve your tax on investment profits.
Capital Losses
Use capital losses to offset capital gains. Losses can be carried forward indefinitely until used.
Timing of Sales
Time asset sales to manage tax brackets. Spread gains across financial years or offset with losses.
Main Residence Exemption
Your family home is generally CGT-free. Partial exemptions apply if used for income-producing purposes.
CGT Calculation Example:
Investment Property Sale:
Purchase price: $400,000 (3 years ago)
Sale price: $550,000
Selling costs: $15,000
Capital gain: $135,000
With 50% discount: $67,500 taxable
Tax at 32.5% rate: $21,937
Without discount: $43,875 tax
Discount saves: $21,938
Superannuation Tax Strategies
Superannuation offers some of the best tax benefits available to Australians. Understanding these can dramatically improve your retirement outcomes.
Concessional Contributions (Tax Deductible):
- Employer contributions: Superannuation Guarantee (11.5% in 2025)
- Salary sacrifice: Reduce taxable income, pay 15% tax in super
- Personal deductible: Available to self-employed and some employees
- Annual cap: $30,000 (2024-25)
Tax Benefits of Super Contributions:
Salary Sacrifice Example:
Gross salary: $80,000
Salary sacrifice: $10,000
Taxable income: $70,000
Tax savings:
Without sacrifice: $16,717 tax
With sacrifice: $14,217 tax + $1,500 super tax
Net saving: $1,000 per year
Carry-Forward Contributions:
If your super balance is under $500,000, you can use unused concessional contribution caps from the previous 5 years.
Property Investment Tax Strategies
Property investment offers unique tax benefits in Australia, but understanding the rules is crucial for compliance and optimisation.
Negative Gearing:
- Offset rental losses against other income
- Deduct interest, rates, insurance, maintenance
- Depreciation on building and fixtures
- Must have genuine intent to make profit
Property-Related Deductions:
Interest Expenses
Loan interest is fully deductible for investment properties. Consider interest-only loans to maximise deductions.
Maintenance & Repairs
Immediate deduction for repairs maintaining property condition. Improvements are capital expenses.
Depreciation
Building allowance (2.5% for post-1987 properties) and plant & equipment depreciation.
Other Expenses
Property management fees, insurance, council rates, advertising for tenants, travel to inspect property.
Small Business Tax Strategies
Small businesses have access to numerous tax concessions and strategies not available to employees.
Small Business Concessions (Turnover < $10 million):
- Tax rate: 25% company tax rate (vs 30% for larger companies)
- Lower tax threshold: $8,001-$200,000 at 25% for unincorporated
- Instant asset write-off: $150,000 for eligible assets
- CGT concessions: 50% reduction, retirement exemption, rollover relief

Pros: Simple, individual tax rates
Cons: No asset protection, higher tax at high incomes
Partnership
Pros: Income splitting possible
Cons: Joint liability, individual tax rates
Company
Pros: 25% tax rate, asset protection
Cons: More complex, double taxation
Trust
Pros: Income distribution flexibility
Cons: Complex, potential tax on undistributed income
