What is the CGT 50% Discount and When Does It Apply?

Published 26 June 2026 · Last updated 26 June 2026

Quick Answer

The CGT 50% discount allows Australian individuals to reduce their capital gains tax by half if they hold an asset for over 12 months. This applies to properties, shares, and other eligible investments. Companies do not qualify for the discount, and different rules apply to super funds. Speak with an accountant to confirm eligibility.

The Capital Gains Tax (CGT) 50% discount is a significant tax concession available to Australian investors. It allows individuals to reduce the capital gain on an investment property by 50%, provided the asset is held for more than 12 months. This discount is crucial for property investors looking to maximise their after-tax returns.

How the CGT 50% Discount Works

Under the Income Tax Assessment Act 1997, individuals, trusts, and superannuation funds can access the CGT discount. For individuals, the discount is 50%, while super funds receive a 33.33% discount. Companies, however, are not eligible for this concession. The key requirement is that the asset must be held for at least 12 months before disposal. This rule is intended to encourage long-term investment rather than short-term speculation. It's important to note that the discount applies only to the net capital gain after offsetting any capital losses.

A common misconception is that the discount applies automatically or universally to all investment properties. However, the discount only applies to capital gains realised on properties held for over a year. Moreover, it doesn't apply to properties purchased after certain legislative changes or those held through a company structure.

How This Works in Practice

Let's consider a scenario: you purchase a 2-bedroom apartment in Fortitude Valley, Brisbane, for $800,000 in 2010 and sell it in 2023 for $1,200,000. Your capital gain is $400,000. Assuming no capital losses, as an individual, you can apply the 50% discount, reducing the taxable gain to $200,000. If your marginal tax rate is 37%, your CGT liability would be $74,000. Without the discount, this liability would have been $148,000. Thus, the CGT 50% discount saves you $74,000 in tax.

Professional Insight

In our experience, many investors overlook the impact of holding periods on CGT liabilities. One thing we frequently see is investors selling just shy of the 12-month mark due to lack of planning. What most investors don't realise is that even a day short of 12 months can disqualify them from the discount, leading to significantly higher tax bills. Additionally, renovations and improvements can affect the cost base calculation, impacting the potential gain. Always ensure your records are meticulous, particularly around acquisition and improvement costs, as these can be critical in calculating your cost base accurately.

When Does the Answer Change?

  • Properties Held in a Company Structure: Companies are not eligible for the CGT discount. Gains made through a corporate entity are fully taxable.
  • Assets Acquired Before 21 September 1999: These may have the option of using indexation to adjust the cost base for inflation instead of the discount.
  • Properties in Self-Managed Super Funds (SMSFs): The discount is reduced to 33.33% for assets held in super funds.
  • Properties Sold Within 12 Months: No discount applies if the property is sold within a year of acquisition.
  • Non-Residents: From 8 May 2012, non-residents are not eligible for the CGT discount on capital gains accrued after this date.
  • When Should You Seek Professional Advice?

    The application of the CGT 50% discount can vary based on individual circumstances, such as the ownership structure of the property and your residency status. A Chartered Quantity Surveyor can assist with cost base calculations, while an accountant can provide advice tailored to your tax situation. Professional advice is crucial to ensure compliance and optimise tax outcomes.

    What to Do Next

  • Review Your Investment Holding Periods: Ensure you're aware of when your assets qualify for the CGT discount.
  • Consult with an Accountant: Get advice on how the CGT discount applies to your specific situation.
  • Maintain Accurate Records: Keep detailed records of all acquisition and improvement costs.
  • Consider Timing of Sales: Plan property sales carefully to maximise tax benefits.
  • Evaluate Ownership Structures: Assess whether your current property ownership structure is tax-efficient.
  • Stay Informed on Legislative Changes: Regularly check for updates on tax laws that may affect your investments.
