What Is a CGT Rollover and When Can I Use It?

Published 26 June 2026 · Last updated 26 June 2026

Quick Answer

A CGT rollover allows deferral of capital gains tax (CGT) liability when specific conditions are met, such as during a business restructure or asset replacement. Under Australian tax law, rollovers are available for small business concessions, marriage breakdowns, and involuntary asset disposals. Consult a tax professional to ensure compliance and benefit maximisation.

A Capital Gains Tax (CGT) rollover is a provision within Australian tax law that allows you to defer the payment of CGT on certain transactions. This can be incredibly beneficial in scenarios like business restructures, asset replacements, or specific life events like marriage breakdowns. Essentially, a rollover postpones the capital gains tax liability to a future date, typically when the asset is eventually sold or disposed of on different terms.

Under current Australian tax law, particularly the Income Tax Assessment Act 1997, various types of rollovers exist, including those for small business concessions, marriage breakdowns, and involuntary disposals of assets. Each type of rollover has its own set of conditions and compliance requirements. A common misconception is that all property transactions qualify for a rollover, which is not the case. Specific criteria must be met to utilise these concessions effectively.

To see how this plays out, consider a practical example. Suppose you own a small business and decide to restructure it. You transfer an asset worth $500,000 to a new company as part of this restructure. Under the small business CGT rollover provisions, you may defer the CGT that would typically be due on this transfer. Assuming a 37% marginal tax rate, deferring this could mean not having to pay approximately $185,000 in CGT immediately. Instead, the tax liability is transferred to the new entity and will become payable when the asset is eventually sold.

In our experience reviewing thousands of properties across Australia, investors often overlook the strategic use of CGT rollovers during business restructures. Many assume that deferring tax is a permanent solution, which it is not. The liability still exists and will need to be addressed eventually, potentially affecting cash flow planning. Another common oversight is failing to document the transaction properly, which can lead to compliance issues with the ATO.

The answer can differ depending on your situation. For example, if you are involved in a marriage breakdown, specific rollovers allow for the transfer of assets between parties without immediate CGT liability. Similarly, if your property is compulsorily acquired by a government authority, you may qualify for a rollover. However, these scenarios have unique conditions that must be meticulously followed.

Certain aspects of CGT rollovers depend significantly on individual circumstances. A Chartered Quantity Surveyor can help identify eligible assets and ensure compliance with the intricate rules governing these rollovers. Coupled with advice from your accountant, this ensures you maximise available benefits while adhering to tax obligations.

  • Frequently Asked Questions

    What is a CGT rollover?

    A CGT rollover allows you to defer the capital gains tax payable on the disposal of an asset under certain conditions, such as during business restructures or involuntary disposals.

    Can I use a CGT rollover for residential properties?

    Generally, CGT rollovers are not applicable to residential properties unless specific conditions are met, such as in cases of compulsory acquisition or marriage breakdown.

    How does a CGT rollover affect my tax return?

    Are there state-specific variations for CGT rollovers?

    CGT is governed by federal law, so the rules generally apply nationwide. However, state-specific property laws can influence the timing and conditions of a rollover.
