What is the 50% CGT Discount and How Do I Qualify?

Published 26 June 2026 · Last updated 26 June 2026

Quick Answer

The 50% CGT discount allows individual investors to reduce their capital gain by half if they hold the asset for at least 12 months. This applies to assets like property and shares. Companies, however, do not receive this discount. Ensure compliance with the ATO's holding period rules to benefit from this tax reduction.

Australian investors can benefit significantly from the 50% Capital Gains Tax (CGT) discount. This discount allows individuals to halve their capital gain amount, reducing their taxable income when they sell an asset held for at least 12 months. This incentive is designed to reward long-term investment, but it's crucial to understand the specific criteria and potential pitfalls to make the most of it.

How the 50% CGT Discount Works

Under Division 115 of the Income Tax Assessment Act 1997, the 50% CGT discount applies to individual investors who hold a capital asset, such as property or shares, for more than 12 months. The discount effectively reduces the capital gain included in your taxable income by 50%, thus lowering the amount of tax payable. It's important to note that this discount is not available to companies, but trusts and superannuation funds have different discount rates.

A common misconception is that any asset sale qualifies for the discount as long as the 12-month period is met. However, the discount is only applicable to assets acquired after 20 September 1985, and the asset must not be used for personal, domestic, or private purposes.

How This Works in Practice

Consider an investor who purchased a 2009-built 2-bedroom apartment in Fortitude Valley, Brisbane, for $700,000. After holding the property for 5 years, they sell it for $900,000. The capital gain is $200,000. With the 50% CGT discount, only $100,000 is added to their taxable income. Assuming a 37% marginal tax rate, they would pay $37,000 in capital gains tax instead of $74,000, saving $37,000 in tax.

Professional Insight

In our experience, many investors overlook the importance of the acquisition date and the exact holding period. One thing we frequently see is investors mistakenly believing that the discount applies to properties used as a primary residence. What most investors don't realise is the impact of partial year ownership on the eligibility for the discount. Additionally, joint ownership of a property can complicate the calculation, as each owner must qualify separately.

When Does the Answer Change?

  • Assets Held in a Company: Companies are not eligible for the 50% CGT discount.
  • Assets Held for Less Than 12 Months: If you sell an asset before the 12-month mark, you won't qualify for the discount.
  • Pre-1985 Assets: Assets acquired before 20 September 1985 are exempt from CGT altogether, making the discount irrelevant.
  • Superannuation Funds: Superannuation funds receive a 33.33% discount, not 50%.
  • Partial Year Ownership: If you only own the asset for part of the year, you must ensure the total holding period exceeds 12 months.
  • When Should You Seek Professional Advice?

    Determining eligibility for the 50% CGT discount can be complex, especially with joint ownership, partial year holdings, or when assets are held in trusts. A Chartered Quantity Surveyor can assist in determining the cost base and potential CGT implications, while an accountant can provide advice on tax-related matters. Professional advice is crucial to ensure compliance with ATO rules and to maximise tax benefits.

    What to Do Next

  • Review Your Asset Portfolio: Identify which assets are eligible for the 50% CGT discount.
  • Check Holding Periods: Ensure that each asset has been held for more than 12 months.
  • Consult with a Chartered QS: Get a professional valuation to determine the accurate cost base of your properties.
  • Speak to Your Accountant: Discuss your CGT liability and strategies to minimise tax.
  • Review Ownership Structures: Ensure that the ownership structure of your assets aligns with your tax strategy.
  • Plan Future Investments: Consider the holding period and potential CGT implications before purchasing new assets.
