How Does a Rental Property Loss Reduce My Income Tax?

Published 26 June 2026 · Last updated 26 June 2026

Quick Answer

In Australia, rental property losses can reduce your taxable income through negative gearing. This occurs when deductible expenses, including interest, exceed rental income, creating a loss that offsets other income. This reduction is reflected in your tax return and can significantly lower your tax payable, depending on your marginal tax rate.

Rental property losses can be a strategic tool in reducing your taxable income in Australia, primarily through a concept known as negative gearing. This occurs when the total expenses associated with your investment property, such as interest on loans, maintenance costs, and depreciation, exceed the income generated from renting it out. This loss can be deducted from your other income, effectively reducing your taxable income and, consequently, your tax liability.

How Rental Property Loss Reduces Income Tax

Under Australian tax law, you can claim a deduction for expenses related to your investment property, even if those expenses exceed your rental income. This is known as negative gearing. The key expenses that can be claimed include interest on your mortgage, maintenance costs, property management fees, and depreciation of assets under Division 40 and capital works under Division 43 of the Income Tax Assessment Act 1997. This loss is then used to offset your other taxable income, such as salary or business income, thereby reducing the amount of tax you need to pay.

A common misconception is that negative gearing only benefits wealthy investors. However, it is a strategy available to any property investor, regardless of their income bracket, as it depends on the relationship between rental income and deductible expenses, not the investor's income.

How This Works in Practice

Consider a scenario where you own a 2009-built 2-bedroom apartment in Fortitude Valley, Brisbane, purchased for $750,000. Your annual rental income is $30,000. However, your deductible expenses, including $25,000 in interest, $5,000 in maintenance and management fees, and $3,000 in depreciation, total $33,000. This results in a rental loss of $3,000.

If you're on a 37% marginal tax rate, this $3,000 loss reduces your taxable income by the same amount, saving you approximately $1,110 in tax for the year. Over time, these savings can significantly impact your overall investment return.

Professional Insight

In our experience, many investors overlook the importance of accurate record-keeping for all deductible expenses. One thing we frequently see is investors underestimating the impact of depreciation. By not obtaining a professional tax depreciation schedule, they miss out on claiming the full extent of their entitlements under Division 40 and Division 43. Additionally, what most investors don't realise is the potential for long-term capital growth that can offset short-term losses, making negative gearing a viable strategy even in a volatile market.

When Does the Answer Change?

  • Post-9 May 2017 Acquisitions: If you purchased a second-hand residential property after this date, you cannot claim depreciation on existing plant and equipment.
  • Pre-1987 Buildings: Properties built before this year generally do not qualify for Division 43 capital works deductions unless significant renovations have been made.
  • Properties Held in an SMSF: Different rules apply, particularly concerning the impact of tax losses within a superannuation context.
  • Joint Ownership: Losses are apportioned according to ownership percentage, affecting each owner's taxable income differently.

When Should You Seek Professional Advice?

While the principles of negative gearing are straightforward, the specifics can vary significantly based on individual circumstances, such as your overall financial situation, the nature of your property, and changes in tax law. It's advisable to consult with a Chartered Quantity Surveyor to ensure your depreciation claims are maximised and accurate. An accountant can further assist in understanding how these losses integrate with your broader tax strategy.

What to Do Next

  • Gather Documentation: Ensure all property-related expenses are well-documented.
  • Consult a QS: Obtain a tax depreciation schedule to maximise your deductions.
  • Review Your Tax Position: Work with an accountant to integrate property losses into your tax strategy.
  • Consider Long-Term Strategy: Assess how negative gearing fits with your long-term investment goals.
  • Stay Informed: Keep up-to-date with any legislative changes affecting rental property deductions.
  • Evaluate Property Performance: Regularly review your property's financial performance and potential for capital growth.
  • Frequently Asked Questions
