How Investment Property Tax Works in Australia

Understanding the fundamentals (FY 2025–26)

💰 Rental Income: Taxed at Your Marginal Rate

All rental income from investment properties is taxable and added to your other income (salary, business income). You pay tax at your personal marginal tax rate, which ranges from 19% to 45% depending on your total income.

Example: If you earn $90,000 salary + $20,000 rental income:

  • • Total taxable income: $110,000
  • • Marginal tax rate: 37% (for income $135,001-$190,000 bracket)
  • • Tax on rental income: $20,000 × 37% = $7,400

✅ Tax-Deductible Expenses for Investment Properties

Immediate Deductions:

  • • Loan interest (not principal repayments)
  • • Council rates and water charges
  • • Insurance premiums (building, landlord, contents)
  • • Property management fees (6-10% of rent)
  • • Repairs & maintenance (fixing existing issues)
  • • Strata/body corporate fees
  • • Advertising for tenants

Depreciation (Claimed Over Time):

  • • Division 43: Building structure (2.5% per year for post-1987 properties)
  • • Division 40: Plant & equipment (carpets, appliances, blinds) using diminishing value or prime cost method
  • • Capital improvements: Depreciated, not immediately deductible

⚠️ Important: You cannot claim deductions for: principal loan repayments, personal use of the property, capital improvements (these are depreciated), or purchase costs (stamp duty, legal fees — these affect CGT only).

🔻 Negative Gearing: How Losses Reduce Your Tax

Negative gearing occurs when your rental property expenses (including interest, depreciation, and all deductible costs) exceed your rental income. The loss can be offset against your other taxable income (like your salary), reducing your overall tax bill.

Real Example: Negatively Geared Property

Annual rental income:$28,000

Annual expenses:

Loan interest:$22,000
Rates, insurance, management:$6,500
Repairs & maintenance:$2,500
Depreciation (Div 40 + 43):$7,500
Total expenses:$38,500
Rental loss (negative gearing):-$10,500

Tax Benefit Calculation:

Your salary:$95,000
Rental loss offset:-$10,500
Taxable income:$84,500
Tax saving (at 37% rate):$3,885

Key insight: While you lose $10,500 on the property, the tax benefit of $3,885 reduces your out-of-pocket loss to $6,615. Many investors accept short-term losses for long-term capital gains (property value appreciation).

🏠 Capital Gains Tax (CGT) When Selling

When you sell an investment property, you'll pay CGT on the profit (sale price minus purchase price and costs). However, if you hold the property for more than 12 months, you qualify for a 50% CGT discount.

Example: Selling after 5 years

  • • Purchase price (2020): $500,000
  • • Sale price (2025): $700,000
  • • Capital gain: $200,000
  • • CGT discount (50%): $100,000 taxable gain
  • • Tax (at 37% marginal rate): $37,000

Note: Without the 12-month discount, you'd pay $74,000 tax on the full $200,000 gain. Holding long-term saves $37,000!

⚠️Common Tax Mistakes Landlords Make

  • 1. Not claiming depreciation: Most landlords miss out on $5,000-$15,000 per year because they don't get a depreciation schedule from a quantity surveyor.
  • 2. Claiming principal repayments: Only loan interest is deductible, not the principal portion of your mortgage repayment.
  • 3. Mixing personal and investment use: If you use the property personally for part of the year, you must apportion expenses and rental income.
  • 4. Immediately claiming capital improvements: Renovations, extensions, and capital works must be depreciated over time (Division 43), not claimed in one year.
  • 5. No documentation: Keep all receipts, invoices, and bank statements. The ATO can request proof of expenses for up to 5 years.

Important Tax Considerations

  • • Depreciation schedules: Building depreciation (Div 43) applies at 2.5%/year for post-1987 properties or 4%/year for older renovations. Plant & equipment uses diminishing value or prime cost methods.
  • • Interest-only vs P&I loans: Only the interest portion of loan repayments is tax-deductible, not principal repayments.
  • • Negative gearing: Rental losses offset your other taxable income (salary, business income). The tax benefit depends on your marginal tax rate.
  • • Capital gains tax (CGT): This calculator does not include CGT on property sale. You may be liable for CGT when selling, with a 50% discount if held over 12 months.
  • • Repairs vs improvements: Immediate repairs are fully deductible; capital improvements are depreciated over time.
