What is Negative Gearing and How Does It Affect My Tax?

Published 26 June 2026 · Last updated 26 June 2026

Quick Answer

Negative gearing occurs when the cost of owning an investment property exceeds the income it generates, resulting in a tax-deductible loss. This can reduce your taxable income, potentially lowering your tax bill. Under Australian tax law, these losses can be offset against other income, such as your salary, to achieve tax savings.

Negative gearing is a tax strategy that Australian property investors use to offset the costs of owning an investment property against their taxable income. This occurs when the expenses related to the property, such as mortgage interest, maintenance, and depreciation, exceed the rental income it generates. Under Australian tax law, this loss can be deducted from your other income, potentially reducing your overall tax liability.

How Negative Gearing Works

In practice, negative gearing means that the investment property operates at a loss, but this loss is not necessarily a negative outcome. According to the Australian Taxation Office (ATO), these losses can be applied against other forms of income, such as your salary or business profits. This can result in a lower taxable income, effectively reducing the amount of tax you owe. The most common misconception is that negative gearing is only beneficial if you're making a loss, whereas it is actually a strategy to leverage tax benefits while waiting for property capital appreciation.

How This Works in Practice

Consider a scenario where you purchase a 2-bedroom apartment in Melbourne for $800,000. The annual rental income is $30,000, while the mortgage interest and other deductible expenses total $40,000. This results in a $10,000 loss. If your marginal tax rate is 37%, you can reduce your taxable income by this loss, saving $3,700 in tax for that year. Over time, as property values rise, the capital gain can also be realised upon sale, potentially outweighing the initial losses.

Professional Insight

In our experience, investors often overlook the importance of cash flow management when negatively gearing. While tax savings are attractive, it's crucial to ensure you can cover the shortfall between rental income and expenses. One thing we frequently see is investors not accounting for potential interest rate rises, which can increase the cost of borrowing and affect the viability of negative gearing. Moreover, many investors don't realise the benefits of a comprehensive depreciation schedule, which can significantly increase tax deductions.

When Does the Answer Change?

Negative gearing's effectiveness can vary based on several factors:

  • Post-2017 Purchases: If you purchased a second-hand residential property after 9 May 2017, you cannot claim Division 40 depreciation on previously used plant and equipment.
  • Interest Rate Changes: Rising interest rates can increase expenses, affecting the loss and tax benefit calculations.
  • Property Use: If the property is used for personal reasons part of the year, deductions may need adjustment.
  • Commercial Properties: Different rules and potential income streams can affect how negative gearing applies.
  • When Should You Seek Professional Advice?

    While negative gearing can offer tax benefits, its effectiveness depends on individual circumstances like income level, property type, and long-term financial goals. Consulting with a Chartered Quantity Surveyor can optimise your depreciation claims, while an accountant can help tailor a tax strategy to your situation. This professional guidance ensures you're not missing out on potential deductions and are fully compliant with ATO regulations.
