Small Business CGT Concessions: A Clear Guide to Maximising Your Return
The decision to sell a significant asset, such as your business, is a major milestone, but it often comes with a daunting question: how much of your hard-earned return will be lost to Capital Gains Tax? The fear of a massive tax bill, coupled with the complexity of ATO rules, can be overwhelming. The good news is that the small business CGT concessions are specifically designed to provide significant relief, but only if you know how to navigate them correctly.
As your trusted partner, we’ve created this guide to turn that complexity into clarity. We will break down the four key concessions into simple, actionable steps so you can feel confident in your tax strategy. You will learn how to determine your eligibility, understand how each concession works, and find the support you need to legally reduce—or even eliminate—your tax liability. It’s time to ensure you maximise the financial rewards of your hard work.
What Are the Small Business CGT Concessions? (And Why They Matter)
When you sell a capital asset—such as your business—for more than its cost base, the profit you make is considered a capital gain. In essence, Capital gains tax in Australia is the tax levied on this profit. For a business owner, a sale is a significant financial event where years of hard work and value creation are realised, potentially triggering a substantial tax bill that can erode your final proceeds.
This is precisely where the small business CGT concessions become an invaluable tool. Offered by the Australian Taxation Office (ATO), these provisions are specifically designed to help you reduce, defer, or in some cases, completely eliminate the tax you owe. Understanding them is critical to protecting the financial outcome of your business exit.
To help clarify these important concepts, we recommend watching this helpful overview:
The Goal: Rewarding Small Business Owners
The government’s intent behind these concessions is clear: to reward the immense effort, dedication, and personal risk that entrepreneurs invest in building a successful business. They acknowledge that for many owners, their business is their primary asset and nest egg. By providing vital tax relief, these concessions support your transition to a secure retirement or help you launch your next venture, ensuring your years of hard work translate into tangible financial security.
The Four Types of Concessions at a Glance
Navigating the concessions starts with understanding the four main options available. While the eligibility rules are complex and require professional guidance, here is a brief look at how each one can support you:
-
15-year exemption: Potentially the most powerful concession, it allows you to disregard the entire capital gain if you have owned the business asset for at least 15 years and are retiring or permanently incapacitated.
-
50% active asset reduction: This allows you to reduce the capital gain on an active business asset by 50% after applying any capital losses.
-
Retirement exemption: You can choose to disregard a capital gain up to a lifetime limit (currently A$500,000). If you are under 55, the exempt amount must be contributed to a complying superannuation fund.
-
Rollover: This allows you to defer the capital gain by acquiring a replacement active asset or making a contribution to your super fund. This effectively "rolls over" the tax liability to a later time.
The First Hurdle: Do You Meet the Basic Eligibility Conditions?
Before you can access the significant tax savings offered by the small business CGT concessions, you must first pass a series of basic eligibility tests set by the ATO. Getting this foundational step right is non-negotiable; failing to meet these conditions means the concessions are simply not available to you. Use the following points as a self-assessment checklist to determine whether you are on the right track.
The rules governing capital gains tax for business can be complex, and these initial tests involve precise calculations. While this guide provides clarity, professional verification is crucial to ensure you proceed with confidence.
Test 1: Are You a Small Business Entity?
The most direct path to eligibility is by qualifying as a Small Business Entity (SBE). This is determined by the aggregated annual turnover test. To pass, your business must have a turnover of less than $2 million for the income year. ‘Aggregated’ is the keyword here; it includes the annual turnover of your business plus the turnover of any entities connected or affiliated with you.
Test 2: The Maximum Net Asset Value (MNAV) Test
If your turnover exceeds the $2 million threshold, don’t worry—there is an alternative. You can still meet the basic conditions if you pass the Maximum Net Asset Value (MNAV) test. This test requires the total net value of your assets (and those of connected entities) to be no more than $6 million just before the CGT event. Crucially, certain assets are excluded from this calculation, such as your primary residence, personal use assets, and superannuation balances.
Test 3: The Active Asset Test
The asset you are selling must be considered an ‘active asset’. In simple terms, this means the asset was used or held ready for use in the course of carrying on a business. Think of your business premises, machinery, equipment, and goodwill—these are typically active assets. In contrast, assets whose main purpose is to derive rent, interest, or dividends (like an investment property or most shares) are generally not. The asset must also have been active for at least half of its ownership period.
Additional Conditions for Shares and Trusts
Selling shares in a company or units in a trust introduces additional requirements. The entity itself must meet the MNAV or turnover test, and the asset must satisfy the active asset test. Additionally, you must be a CGT concession stakeholder in the company or trust, which involves meeting a ‘significant individual’ test, ensuring a genuine connection to the underlying small business.

A Deep Dive into the Four Small Business CGT Concessions
Understanding the intricacies of the four small business CGT concessions is the key to unlocking significant tax savings. Each serves a unique purpose and must be considered in a specific order to maximise its benefit. As your trusted partner, we’ve broken them down to provide clear, actionable guidance.
It’s crucial to apply the concessions in the correct sequence. If you qualify for the 15-year exemption, the process stops there. If not, you would typically apply the 50% active asset reduction first, followed by the retirement exemption and/or the small business rollover to the remaining gain.
The 15-Year Exemption: The Complete Tax Wipeout
This is the most powerful concession available, allowing you to disregard the entire capital gain from the sale of an active asset. It essentially wipes out your profit entirely.
-
Who it’s for: Long-term business owners who are ready to retire.
-
Key conditions: You must have continuously owned the active asset for at least 15 years, be aged 55 or over, and the sale must be in connection with your retirement.
-
Example: David, aged 62, sells the engineering firm that he has owned and operated for 18 years. Because he meets the conditions, he can apply the 15-year exemption and pay no capital gains tax on the sale, securing his entire profit for retirement.
The 50% Active Asset Reduction: The Go-To Concession
If you don’t qualify for the 15-year exemption, this is often the next concession to consider. It allows you to reduce your capital gain by 50%. This is applied after the general 50% CGT discount (for assets held for more than 12 months), effectively reducing the remaining gain by a further 50%.
- Example: A company sells a warehouse used in its operations for 10 years, resulting in a capital gain of A$400,000. The general 50% discount reduces it to A$200,000. Applying the 50% active asset reduction reduces it by half again, leaving a taxable gain of just A$100,000.
The Retirement Exemption: Boost Your Superannuation
This concession allows you to exempt a capital gain up to a lifetime limit of A$500,000. You do not have to contribute to a superannuation fund if you are over 55. However, if you are under 55, you must contribute the exempt amount into a complying super fund to receive the tax benefit.
- Example: After applying other discounts, Sarah has a remaining capital gain of A$300,000 from selling her shares in her small business. At age 48, she can use the retirement exemption to make this A$300,000 gain tax-free by contributing it to her superannuation fund.
The Small Business Rollover: Defer and Reinvest
Instead of eliminating the gain, the rollover concession allows you to defer it. This is ideal if you plan to continue operating by purchasing a new asset. The deferred capital gain is only triggered when you sell the replacement asset or your circumstances change. You generally have two years to acquire the new asset.
Navigating these powerful small business cgt concessions requires a proactive and strategic approach. With careful planning, they can make a profound difference to your financial outcome when you decide to sell your business assets.

Putting It All Together: A Practical Case Study
Theory is helpful, but seeing the numbers in action truly highlights the value of strategic tax planning. Let’s walk through a practical example with a hypothetical business owner, David, to demonstrate how these concessions can make a life-changing difference when you sell your business.
David is 60 years old and, after a long and successful career, decides to sell the active assets of his manufacturing business to fund his retirement.
Calculating the Initial Capital Gain
First, we establish the baseline capital gain without any tax relief. This initial figure shows the significant tax liability a business owner could face without proper planning.
-
Sale Price: $2,000,000
-
Cost Base of Assets: $800,000
-
Initial Capital Gain: $1,200,000
Without any concessions, David would face a staggering capital gain of $1.2 million. At the top marginal tax rate, this could result in a tax bill of over $560,000, severely impacting his retirement funds.
Applying the Concessions in Order
This is where professional guidance becomes invaluable. By strategically applying the small business CGT concessions in the correct order, we can methodically reduce David’s taxable gain. As David is over 55 and retiring, he has access to powerful options.
1. **Step 1: Apply the 50% Active Asset Reduction.** Because the assets were used in his active business, David can immediately reduce his capital gain by 50%. The remaining capital gain is now $600,000.
2. **Step 2: Apply the Retirement Exemption.** David can use the retirement exemption to eliminate a further portion of the gain. He applies $500,000 of his lifetime limit to the remaining gain, contributing this amount to his superannuation fund tax-free.
After applying these two key concessions, the final taxable capital gain is reduced to just $100,000.
The Final Result: A Drastic Tax Reduction
The difference is profound. By understanding and correctly applying the available concessions, David has fundamentally changed his financial outcome.
**Initial Taxable Gain:** $1,200,000
**Final Taxable Gain:** $100,000
**Potential Tax Saved:** *Over $500,000*
This case study demonstrates the incredible power of the small business CGT concessions. It’s not just about meeting compliance; it’s about proactively structuring the sale to secure your financial future. Navigating these steps requires careful planning and expert guidance to ensure you maximise your outcome. Let us be your trusted partner on this journey.
Common Pitfalls and Why Expert Guidance is Non-Negotiable
While the potential tax savings are immense, the rules governing the small business CGT concessions are notoriously complex. The Australian Taxation Office (ATO) strictly enforces these rules, and the financial stakes are high. A simple misinterpretation or administrative error can result in the complete loss of concessions, leading to significant tax liability and potential penalties.
Navigating this landscape requires more than just a basic understanding; it demands specialist expertise to ensure you secure the best possible outcome from the sale of your most valuable asset.
Mistakes to Avoid When Claiming Concessions
A minor oversight can invalidate your entire claim. Common, costly errors we help clients avoid include:
-
Incorrectly Calculating Net Assets: The $6 million Maximum Net Asset Value (MNAV) test has strict inclusion and exclusion criteria. A miscalculation here is an immediate disqualification.
-
Failing the ‘Active Asset’ Test: An asset must be used in the business for a specific portion of its ownership period. Technicalities around passive assets, such as certain rental properties, often catch business owners off guard.
-
Missing Critical Deadlines: The small business rollover concession requires you to acquire a replacement asset or make a superannuation contribution within a strict two-year window. Missing this deadline is irreversible.
-
Poor Record-Keeping: The ATO requires clear, comprehensive evidence to substantiate your eligibility. Without it, your claim will likely be denied upon review.

Frequently Asked Questions About Small Business CGT Concessions
Can I claim the small business CGT concessions on a rental property?
Generally, a standard residential rental property does not qualify because it’s considered a passive investment, not an ‘active asset’ used in a business. However, an exception may apply if the property is used in carrying on a business, such as a short-term accommodation business or if it’s integral to another business’s operations. The distinction is critical, and we recommend seeking professional guidance to accurately assess your specific circumstances.
What is the lifetime limit for the small business retirement exemption?
The lifetime limit for the small business retirement exemption is A$500,000 per individual. This is a cumulative cap, meaning you can apply it to capital gains from multiple events until the limit is reached. If you are under 55 when you make the choice, the exempt amount must be contributed to a complying superannuation fund or a retirement savings account for the choice to be valid. This makes it a powerful retirement planning tool.
Do I have to be retiring to use the small business CGT concessions?
No, you are not required to be retired to access all the concessions. While the 15-year exemption specifically requires you to be over 55 and retiring (or permanently incapacitated), the other concessions do not. The 50% active asset reduction and the small business rollover can be applied at any stage of your business journey, provided you meet the other essential eligibility criteria for these specific reliefs.
What happens if I use the rollover but don’t buy a new asset in time?
If you apply the small-business rollover, you typically have a two-year period to acquire a replacement asset. Should you fail to do this within the timeframe, the capital gain you deferred will crystallise in the income year the period ends. This means the original capital gain becomes assessable income, which could result in a significant, often unexpected tax bill. It is vital to have a clear plan for your replacement asset.
Can I apply both the 50% general CGT discount and the small business concessions?
Yes, you can, and doing so can provide a substantial tax benefit. The concessions are applied in a specific order. First, apply any capital losses, then the 50% general CGT discount (for assets held for more than 12 months). After that, you can apply the small business CGT concessions, such as the 50% active asset reduction, to the remaining gain. This strategic layering of discounts is key to maximising your tax savings.
How do the concessions work if I’m selling shares in my company?
When selling shares, additional conditions must be satisfied. The company itself must be a CGT small business entity, and the individual selling the shares must be a ‘significant individual’ in the company (holding at least 20% of voting rights) just before the sale. Furthermore, the market value of the company’s active assets must be at least 80% of its total assets. These rules ensure the concessions are targeted at genuine operating businesses.
