How Negative Gearing Works in Australia
Negative gearing occurs when the total expenses of an investment property exceed the rental income it generates. The resulting net rental loss is deductible against your other assessable income, including your salary, wages, and business income. This reduces your overall taxable income and therefore your tax liability for the year. The Australian Taxation Office (ATO) permits this deduction under Division 36 of the Income Tax Assessment Act 1997, provided the property is genuinely available for rent and you maintain proper records of all income and expenses.
The key deductible expenses include loan interest on the investment portion of the mortgage, council and water rates, landlord insurance, property management fees, repairs and maintenance, depreciation on the building structure (Division 43 at 2.5% per year for residential buildings constructed after 15 September 1987), and depreciation on fixtures and fittings (Division 40). The property management fee is typically charged as a percentage of collected rent, usually between 5% and 10% depending on the state and agency.
Understanding the Tax Benefit Calculation
The tax benefit of negative gearing depends on your marginal tax rate. The higher your taxable income, the greater the tax saving per dollar of rental loss. For example, if your salary places you in the 37% tax bracket (income between $120,001 and $180,000 for 2024-25), every dollar of net rental loss saves you 37 cents in income tax plus 2 cents in Medicare levy, totalling 39 cents. This calculator uses the ATO's 2024-25 individual tax rates including the 2% Medicare levy to determine your marginal rate with and without the rental loss, giving you the precise annual tax benefit.
The after-tax cost of holding the property equals the net rental loss minus the tax benefit. This represents the real out-of-pocket cost to you after the ATO effectively subsidises part of the loss through a lower tax bill. Dividing this by 52 gives the weekly holding cost, which is useful for comparing against expected capital growth to determine whether the investment makes financial sense over time.
Depreciation and Building Allowance
Building depreciation under Division 43 allows you to claim 2.5% of the original construction cost each year over 40 years for residential properties built after 15 September 1987. This is a non-cash deduction that increases your rental loss on paper without requiring an actual cash outflow. For a property with $350,000 in construction cost, the annual Division 43 deduction is $8,750. A quantity surveyor can prepare a tax depreciation schedule that also identifies Division 40 deductions for plant and equipment items such as carpet, blinds, hot water systems, and air conditioning units. These schedules typically cost $600-$800 and can add thousands in additional annual deductions.
Tips for Maximising Your Negative Gearing Benefit
To optimise your negative gearing strategy, consider these factors. First, ensure your loan is structured as interest-only during the growth phase, as principal repayments are not deductible. Second, obtain a depreciation schedule from a registered quantity surveyor to capture all Division 40 and Division 43 deductions. Third, keep meticulous records of every expense including receipts for repairs, statements from the body corporate, and annual summaries from your property manager. Fourth, review your vacancy rate assumptions realistically based on your suburb's rental demand to avoid overstating expected income. Finally, consider the overall investment return including expected capital growth, rental yield, and the after-tax holding cost when deciding whether negative gearing aligns with your long-term financial goals.
Frequently Asked Questions
What is negative gearing in Australia?
Negative gearing occurs when the costs of owning an investment property (loan interest, rates, insurance, management fees, depreciation, maintenance) exceed the rental income it generates. The net rental loss can be deducted from your other taxable income, such as salary, reducing your overall tax liability for the financial year.
How does negative gearing reduce my tax?
The net rental loss is subtracted from your total assessable income before tax is calculated. If you earn $100,000 salary and have a $15,000 rental loss, your taxable income becomes $85,000. At a marginal rate of 32% (30% plus 2% Medicare levy), the tax saving is approximately $4,800 per year. The higher your marginal rate, the greater the tax benefit.
What expenses can I claim on a negatively geared property?
Deductible expenses include loan interest (not principal repayments), council rates, water rates, landlord insurance, property management fees, advertising for tenants, repairs and maintenance, body corporate or strata fees, pest control, travel to inspect the property (limited), legal expenses for leases, and depreciation on the building (Division 43) and fixtures (Division 40).
What is Division 43 building depreciation?
Division 43 of the Income Tax Assessment Act allows you to claim a capital works deduction of 2.5% per year on the original construction cost of residential buildings constructed after 15 September 1987. For a property with $350,000 in construction cost, this provides an $8,750 annual deduction over 40 years. This is a non-cash deduction that increases your rental loss without any actual expense.
Is negative gearing still allowed in Australia?
Yes, negative gearing remains a legitimate tax strategy under Australian tax law as of 2024-25. There have been policy debates about limiting or abolishing it, but no legislative changes have been enacted. The ATO permits the deduction of net rental losses against other assessable income, provided the property is genuinely available for rent at market rates.
What is the difference between negative gearing and positive gearing?
A property is negatively geared when expenses exceed rental income, resulting in a loss that reduces your taxable income. A property is positively geared when rental income exceeds expenses, adding to your taxable income. Negative gearing provides a tax benefit but costs money to hold; positive gearing generates immediate income but increases your tax bill. Many investors start negatively geared and transition to positive gearing as rents rise over time.
