Can You Offset Capital Losses Against Property Gains?

Published 26 June 2026 · Last updated 26 June 2026

Quick Answer

Yes, you can offset a capital loss against your property gains in Australia. Under the ATO's rules, capital losses can be used to reduce capital gains in the same financial year. If losses exceed gains, they can be carried forward to future years. Consult with your accountant to ensure compliance with Division 102 of ITAA 1997.

Capital losses can indeed be offset against capital gains in the context of Australian property investments. This is a critical strategy for investors aiming to minimise their tax liabilities. Under Division 102 of the Income Tax Assessment Act 1997, if you experience a capital loss, you can use this to reduce any capital gains you make in the same financial year. If your losses exceed your gains, you can carry forward the remaining loss to offset against future capital gains. This strategy requires precise record-keeping and understanding of your tax position.

How to Offset Capital Losses Against Property Gains

The primary function of offsetting capital losses against gains is to reduce the taxable capital gains you declare on your tax return. The ATO allows you to use capital losses to offset only against capital gains, not other types of income. This means if you sell an investment property at a loss, that loss can be used to offset any capital gain from another property sale within the same tax year. Importantly, if your losses exceed your gains, these can be carried forward to offset future capital gains, but they cannot be used to create or increase a tax refund by offsetting against other types of income.

How This Works in Practice

Consider a scenario where you own a 3-bedroom house in Melbourne, purchased for $700,000. You sell it for $800,000, resulting in a capital gain of $100,000. In the same financial year, you sell another property at a $30,000 loss. You can offset this loss against your $100,000 gain, reducing your taxable capital gain to $70,000. Assuming you are in the 37% tax bracket, this adjustment saves you approximately $11,100 in taxes.

Professional Insight

In our experience, many investors are unaware that they can carry forward unused capital losses indefinitely, which can be a significant tax planning tool. One thing we frequently see is investors failing to offset losses optimally due to poor record-keeping or misunderstanding the rules. Another common oversight is not realising that capital losses must be applied in the order they were incurred. What most investors don't realise is that losses can only offset gains on assets within the same structure (e.g., personal vs. SMSF).

When Does the Answer Change?

  • Properties Held in an SMSF: Capital gains and losses in SMSFs are treated differently, and professional advice should be sought.
  • Pre-CGT Assets: Properties acquired before 20 September 1985 are exempt from CGT, so losses cannot be realised in the same way.
  • Joint Ownership: Gains and losses must be apportioned according to ownership percentages.
  • Partial Year Purchases: If a property is purchased or sold partway through the year, only the relevant portion of gains/losses applies.
  • When Should You Seek Professional Advice?

    You should consult a professional when dealing with complex scenarios like properties held in trusts or SMSFs, or when you have multiple properties with varying purchase and sale dates. A Chartered Quantity Surveyor can provide accurate cost base assessments, while an accountant can ensure your tax strategy is compliant and optimised.

    What to Do Next

  • Review your investment portfolio to identify potential capital losses.
  • Gather all relevant documentation for property purchases and sales.
  • Consult with a Chartered Quantity Surveyor for accurate cost base calculations.
  • Discuss your situation with an accountant to strategise your capital gains and losses.
  • Keep detailed records of all property transactions and valuations.
  • Plan future property sales with tax implications in mind.
  • Frequently Asked Questions

    Can I offset capital losses from shares against property gains?

    Yes, capital losses from shares can be offset against property capital gains, as both are considered capital assets under the ATO's rules.

    How do capital losses affect my tax return?

    Capital losses reduce your taxable capital gains, lowering your overall tax liability. They must be reported in your tax return, and unused losses can be carried forward.

    Are there state-specific rules for capital gains tax?

    No, capital gains tax is governed by federal legislation and applies uniformly across all Australian states and territories.

    What happens if I have more losses than gains?

    Excess losses can be carried forward to offset future capital gains. They cannot be used to offset other types of income.

    How does holding a property in a trust affect capital gains and losses?

    Capital gains and losses in a trust are distributed to beneficiaries who then declare them on their personal tax returns. Seek advice for trust-specific rules.
