What is the CGT Small Business Concession?

Published 26 June 2026 · Last updated 26 June 2026

Quick Answer

The CGT small business concession allows eligible small business owners to reduce or defer capital gains tax on the sale of business assets. To qualify, your business must meet the basic conditions, including the active asset test and the $2 million turnover or $6 million net asset value test. Consult an accountant to ensure compliance.

The CGT small business concession in Australia is a valuable tax benefit available to eligible small business owners, allowing them to reduce or defer their capital gains tax when selling business assets. Under the Income Tax Assessment Act 1997, these concessions are designed to help small businesses reinvest in growth or retirement. However, navigating the eligibility criteria and understanding the specific conditions can be complex.

To qualify for the small business CGT concession, your business must satisfy several conditions. Firstly, you must be a small business entity with an aggregated turnover of less than $2 million or have a net asset value of $6 million or less. Additionally, the asset in question must pass the active asset test, which generally requires it to have been used in the course of carrying on a business for at least half of the ownership period.

A common misconception is that any small business can automatically claim these concessions. However, the rules are specific, and each condition must be meticulously checked. For example, the active asset test is often misunderstood; simply owning a business asset does not make it eligible. The asset must contribute to the business operations actively.

Take a practical example to see how this plays out. Imagine you own a small café in Melbourne, purchased in 2010 for $300,000. After years of successful operation, you decide to sell the café for $850,000 in 2023. Your business turnover is $1.5 million, and the café building has been used actively throughout your ownership. You qualify for the 50% active asset reduction, reducing the capital gain to $275,000. With the 50% CGT discount for individuals holding the asset for over 12 months, your taxable gain drops to $137,500. At a marginal tax rate of 37%, your tax liability is $50,875.

In our experience reviewing thousands of properties across Australia, many business owners overlook the importance of maintaining accurate records to support their eligibility for the concession. We often see clients who miss out on significant tax savings due to non-compliance with the active asset test or miscalculating their net asset value.

The answer can differ depending on your situation. For instance, if your business is structured as a trust or partnership, different rules apply compared to a sole trader. Additionally, if the asset was acquired before 20 September 1985, it's exempt from CGT altogether. The concessions also vary if you are retiring, as you may be eligible for the retirement exemption, allowing you to disregard some or all of the capital gain.

When it comes to something as complex as the CGT small business concession, professional advice is invaluable. A Chartered Quantity Surveyor can help assess the asset’s eligibility under the active asset test, while an accountant can ensure compliance with turnover and asset value thresholds. Together, they provide a comprehensive strategy to optimise your tax position.

To make the most of the CGT small business concession:

  • Verify your business structure and turnover to confirm eligibility.
  • Ensure the asset meets the active asset test requirements.
  • Maintain detailed records to support your claims.
  • Consult with a Chartered Quantity Surveyor for asset assessments.
  • Discuss with your accountant the implications of the concession on your overall tax strategy.
  • Consider future business plans to utilise the concession effectively.
