Small Business CGT Concessions: Contributing Sale Proceeds to Super
Written by Kurt Armbruster, Financial Adviser | Last reviewed: 18th September 2026
Small business owners often have a significant portion of their net worth tied up in their business assets. Upon the sale of these assets, the capital gains tax (CGT) consequences can be substantial. Fortunately, Australian tax law provides specific concessions that allow eligible small business owners to contribute a portion of their sale proceeds into superannuation, potentially bypassing standard contribution caps.
This strategy can be highly effective in transitioning business equity into a tax-effective retirement environment. However, the qualification criteria, involving net asset value tests and ownership requirements, are notoriously complex. Implementing this strategy requires careful coordination with your accountant to ensure all eligibility thresholds are met and that the contributions are structured correctly to remain compliant with superannuation legislation.
Who is eligible for the small business CGT concessions?
The primary gateway to these concessions involves satisfying basic eligibility criteria, such as the maximum net asset value test threshold of $6 million or the small business entity turnover threshold of $2 million. Additional conditions, such as the active asset test and, for shares or trust interests, the significant individual requirements, must also be met and meticulously documented.
The four small business CGT concessions
Once eligible, business owners can access up to four distinct concessions:
- the 15-year exemption
- the 50% small business reduction
- the retirement exemption
- the small business rollover
How the CGT cap works with super
The 15-year exemption and the retirement exemption are particularly potent, as they enable capital gains to be contributed directly into superannuation under the lifetime CGT cap, completely separate from standard concessional and non-concessional contribution limits. The CGT cap amount is $1,935,000 for 2026-27, and the retirement exemption itself has a $500,000 lifetime limit.
These contributions do still increase your total superannuation balance, which affects future non-concessional contribution eligibility and, for larger balances, Division 296 tax.

Getting the timing and paperwork right
To maximise the utility of the CGT cap, timing and administrative execution must be handled with precision. For instance, contributions utilising the retirement exemption require specific written elections to be lodged with the superannuation fund trustee on or before the contribution is made. Any procedural failure or miscalculation of asset values can result in the payment being treated as an excess contribution, triggering penalty tax rates and administrative headaches.
Turning business value into retirement wealth
By effectively deploying these concessions, small business owners can shelter substantial wealth from capital gains tax while rapidly scaling their superannuation reserves. This strategy transforms unlisted business value into liquid, professionally managed, or SMSF-held investment portfolios. Where the business premises are also being moved into super, see our guides to SMSF commercial property and in-specie transfers.
Given the high financial stakes and regulatory complexity, establishing a joint advisory approach between tax accountants, legal counsel, and financial advisers is essential to achieving an optimal structural outcome.
Small business CGT FAQs
Often, yes. If you qualify for the small business CGT concessions, amounts covered by the 15-year exemption or the retirement exemption can be contributed to super under the lifetime CGT cap, rather than the normal concessional or non-concessional caps. Eligibility depends on turnover or net asset tests, the active asset test and ownership requirements.
The CGT cap amount for 2026-27 is $1,935,000. It is a lifetime limit, indexed each year, for contributions from the sale of qualifying small business assets using the 15-year exemption or the retirement exemption. Contributions under the CGT cap do not count towards your non-concessional contributions cap.
The 15-year exemption can disregard the entire capital gain on an active business asset that you have owned continuously for at least 15 years, provided you are 55 or older and retiring, or permanently incapacitated. It is the most generous of the four concessions and, where it applies, the other concessions are not needed for that gain.
Yes. You must give your fund the approved capital gains tax cap election form on or before the day you make the contribution. Without a valid election, the contribution is counted as non-concessional and may exceed that cap, which can lead to extra tax.
