If you’re planning to sell your business, the CGT retirement exemption could wipe out your capital gains tax — or at least dramatically reduce it — even if you haven’t owned the business for 15 years. Here’s how it works, who qualifies, and what planning steps you need to take before the sale settles.

Capital gains tax on a business sale can be a significant hit — potentially hundreds of thousands of dollars. The retirement exemption, under Division 152-D of the Income Tax Assessment Act 1997, is one of four small business CGT concessions specifically designed to reduce or eliminate that liability. It allows eligible business owners to exclude up to $500,000 of capital gains from their taxable income — over their lifetime — if certain conditions are met.

What Is the CGT Retirement Exemption?

The CGT retirement exemption is a concession under Division 152-D of the ITAA 1997 that permanently excludes up to $500,000 of capital gains from the sale of a qualifying active business asset from your assessable income. This is a lifetime limit — once you’ve used $500,000 of the exemption across all your business sales, it’s gone.

Unlike the CGT 15-year exemption — which requires continuous ownership for at least 15 years and a retirement or incapacity trigger — the retirement exemption has no minimum ownership period. You could have owned the business for two years and still qualify. However, age determines what you do with the exempt amount:

• Aged 55 or over at the time of the CGT event: the exempt amount is yours tax-free. No requirement to contribute to superannuation. You can receive it directly.
• Under 55: the exempt amount must be contributed to a complying superannuation fund or retirement savings account within 30 days of receiving the capital proceeds — or from the date of settlement if proceeds are received later. Miss this window and the exemption is forfeit.

The exemption is available whether you own the business directly as an individual, through a company, or through a trust — though the mechanics differ for each structure, and additional steps are required for entities.

Who Qualifies for the CGT Retirement Exemption?

Eligibility involves two layers: the basic conditions that apply to all four small business CGT concessions, plus conditions specific to the retirement exemption itself.

Basic Eligibility Conditions

You must be a small business entity — either an entity with aggregated annual turnover under $10 million, or one that satisfies the maximum net asset value test (the net value of your CGT assets, excluding your home and certain super assets, is under $6 million at the time of the CGT event).

The asset being sold must be an active asset: used, or held ready for use, in carrying on a business. Business goodwill, business real property you use in the business, and shares or trust interests where the underlying entity runs an active business can all qualify — though shares and trust interests come with additional “significant individual” tests (you generally need to hold at least 20% of the voting rights or distributable income).

The ATO’s guidance on basic conditions for the small business CGT concessions sets out these requirements in full.

Retirement Exemption-Specific Conditions

Once the basic conditions are met, the retirement exemption adds its own requirements:

• You must actively choose to apply the exemption — it is not automatic.
• You must not exceed your remaining lifetime limit. The combined amount you exempt across all CGT events using this concession cannot exceed $500,000.
• If you are under 55, the exempt amount must be contributed to super within 30 days of receiving the capital proceeds.
• If the CGT asset is held by a company or trust, the entity must make a cash payment to the individual equal to the exempt amount — the individual then contributes it to super if under 55. The payment from the entity is generally not assessable to the individual.

Importantly, you do not have to actually retire or stop working. The name of this concession is misleading — it applies to any qualifying business owner selling an active asset, regardless of their future employment or business plans.

How the Retirement Exemption Interacts with Other Concessions

The retirement exemption doesn’t operate in isolation. It sits within a layered system of concessions, and understanding the correct sequence matters — both for maximising the benefit and for avoiding mistakes.

In most cases, the 50% active asset reduction (Division 152-C) is applied first. This halves your capital gain if the asset has been an active asset for at least half of the period you’ve owned it. The retirement exemption is then applied to the reduced (post-50%) capital gain — meaning your $500,000 lifetime cap goes twice as far.

If the CGT 15-year exemption applies, it wipes the entire capital gain — so the retirement exemption isn’t needed for that sale. The 15-year exemption is the most powerful concession, but it requires 15 continuous years of ownership and an age or incapacity trigger. Many business owners won’t meet this test at the time they want to sell.

For business owners who’ve held their business for 8, 10, or 12 years — not yet 15 — the retirement exemption is the primary tool for eliminating capital gains tax on the sale. It works alongside proactive tax planning strategies to maximise your exit position.

The small business CGT rollover (Division 152-E) is also available, allowing you to defer a gain on one business asset if you acquire a replacement — but that’s a separate concession. The full overview is in our CGT small business concessions guide.

Worked Example: Under 55 — Jamie’s Consulting Business

Jamie is 48 and has operated a successful IT consulting business for nine years. He agrees to sell for a price that results in a capital gain of $400,000.

His accountant applies the 50% active asset reduction first: the $400,000 gain becomes $200,000.

Jamie has never used the retirement exemption before, so his full $500,000 lifetime cap is available. He chooses to apply the exemption to the remaining $200,000 gain. Because he is 48 (under 55), he must contribute $200,000 to his superannuation fund within 30 days of receiving the sale proceeds.

Result: Jamie pays $0 capital gains tax. The $200,000 is now inside superannuation — sheltered, invested, and growing towards retirement. For a 48-year-old with 17 years until preservation age, that’s a meaningful head start. And because this contribution is classified as a CGT cap amount, it doesn’t eat into Jamie’s regular concessional or non-concessional contribution caps.

Worked Example: 55 or Over — Maria’s Café

Maria is 62 and sells her café after 12 years of operation. The sale results in a capital gain of $700,000.

Her accountant applies the 50% active asset reduction: the gain is reduced to $350,000.

Maria has not previously used the retirement exemption, so her full $500,000 cap is available. She applies the exemption to all $350,000 of the remaining gain. Because she is 62 (over 55), she can receive this amount directly — no requirement to contribute to super.

Result: Maria pays $0 capital gains tax. She receives the proceeds tax-free and has complete flexibility — whether she boosts super voluntarily, funds retirement living expenses, or invests elsewhere. The entire $350,000 is hers to use as she chooses.

Understanding the $500,000 Lifetime Cap

The $500,000 lifetime limit is one of the most important details of the retirement exemption, and it’s easy to mismanage — particularly if you’ve sold business assets before.

The cap is per individual, not per business or per sale event. If you used $200,000 of the exemption on a previous business sale, you have $300,000 remaining. Apply the exemption to a $400,000 gain on a future sale (after the 50% active asset reduction), and $100,000 of that gain remains taxable — because you’ve exhausted the cap.

The $500,000 limit has also not been indexed for inflation. It’s the same figure it has been for many years. For business owners selling larger businesses where the capital gain — even after the 50% active asset reduction — exceeds $500,000, the retirement exemption alone won’t eliminate the entire taxable gain. Layering it with the active asset reduction and other tax planning strategies becomes critical.

If you’ve previously sold business assets and used part of this exemption, tracking the remaining cap is essential. Your accountant can determine how much you’ve used from prior tax returns and ATO records before you proceed with any new sale.

The Super Contribution Angle: A Planning Opportunity for Under-55s

For business owners under 55, the requirement to contribute to super isn’t just a condition to satisfy — it’s a genuine wealth-building opportunity.

The amount contributed under the retirement exemption is classified as a CGT cap amount. This sits within a separate lifetime cap for super contributions arising from small business CGT concessions — currently $1,780,000 (indexed annually). Critically, this contribution does not count towards your regular concessional or non-concessional contribution caps.

This means a 45-year-old selling a business can potentially contribute up to $500,000 directly into superannuation from the sale proceeds — completely outside the normal annual limits. For someone who hasn’t built a large super balance from regular contributions, this can fast-track their retirement savings in a way that wouldn’t otherwise be possible.

The combination of zero tax on the capital gain and the ability to shelter up to $500,000 into a low-tax superannuation environment has a profound impact on long-term wealth accumulation. But it requires coordinated planning with your accountant — ideally 12 to 24 months before the sale, not after settlement.

Common Mistakes That Cost Business Owners the Exemption

The retirement exemption is powerful, but its strict procedural requirements mean that a missed step — especially the 30-day contribution window — can turn a $0 tax bill into a very large one.

• Missing the 30-day super contribution window. For under-55 business owners, the exempt amount must be in super within 30 days of receiving the capital proceeds. The ATO does not grant extensions. Miss this deadline and the exemption is lost — permanently for that gain.
• Getting advice after the sale has settled. By the time settlement is complete, your options may be limited. Structuring a business exit correctly — choosing the right concessions, checking the 15-year and active asset tests, managing timing — should start 12 to 24 months before the intended sale date.
• Using the exemption when the 15-year exemption would have applied. If you’re approaching 15 years of continuous ownership and are over 55 (or will be), it may be worth deferring the sale. The 15-year exemption covers the entire gain without touching your $500,000 lifetime cap — preserving it for a future sale. Using the retirement exemption unnecessarily wastes that cap.
• Applying the retirement exemption before the active asset reduction. The correct sequence matters. Applying the retirement exemption to the full gain — rather than after the 50% active asset reduction — depletes the lifetime cap twice as fast for the same outcome.
• Assuming the exemption is applied automatically. It is not. You must actively make the choice, and it must be documented correctly in your tax return. If you don’t make the election, you don’t receive the exemption.
