Self-employed Australians receive no Superannuation Guarantee — building super requires deliberate action. In late career, the main tools are personal deductible contributions (up to the $30,000 concessional cap), carry-forward rules for those with TSB under $500,000, and for business owners the small business CGT concessions which can exempt gains from tax and allow super contributions under the $1.865 million CGT cap outside normal limits.
If you are self-employed — a sole trader, partner, or small business owner — and approaching retirement in your fifties or sixties, your superannuation position likely looks different from your salaried peers. Employees have the Superannuation Guarantee (SG) working for them throughout their career: at 12% in 2025-26, that is $12,000 per year flowing into super for every $100,000 of salary, automatically and compulsorily, for their entire working life. Self-employed individuals receive no automatic SG contributions. Every dollar in their super fund has been actively chosen. Many who have prioritised business growth over the decades arrive at their fifties with a super balance that doesn't reflect the scale of what they've built — because most of what they've built sits in the business, not the fund.
The late career is the high-leverage moment to address this. Several tools are specifically suited to self-employed individuals in their final decade before retirement, and combined they can produce very substantial super accumulation in a short time.
How do personal deductible contributions work for the self-employed?
The primary super tool for self-employed individuals is the personal deductible — sometimes called personal concessional — contribution. Unlike salaried employees who access concessional contributions via salary sacrifice through their employer, self-employed individuals can contribute directly from their own bank account and claim a deduction in their personal tax return. The contribution must be made to the super fund first, and then a formal Notice of Intent to Claim a Deduction (ATO form NAT 71121) must be lodged with the fund and acknowledged in writing before the earlier of the date the tax return is lodged or 30 June of the following year. Once acknowledged, the deduction is claimed in the individual's tax return, and the contribution is taxed at 15% inside the fund — rather than at the higher marginal rate that would apply to ordinary business income.
The concessional contributions cap is $30,000 for 2025-26. For self-employed individuals aged 67 to 74, the work test applies — at least 40 hours of gainful employment within a 30-consecutive-day period in the financial year, or a work test exemption for those who met the work test in the prior year with a total super balance below $300,000. Under age 67, no work test applies. Contributions are not possible for those aged 75 or older (other than mandated contributions).
How can carry-forward concessional contributions boost self-employed super balances?
For self-employed individuals whose total super balance was below $500,000 at 30 June 2025, the carry-forward provisions allow the use of unused concessional cap from the prior five financial years. This can significantly increase the available annual deduction in a high-income year. A 60-year-old self-employed individual who has made minimal super contributions over the past five years, and whose balance is comfortably below $500,000, may be able to make a deductible concessional contribution of well over $100,000 in a single year by using the accumulated carry-forward capacity. For a business in its most profitable phase, this is one of the most tax-effective uses of that income.
What small business CGT concessions can reduce or eliminate tax on a business sale?
For business owners whose business has grown in value during their ownership, the small business capital gains tax (CGT) concessions in Division 152 of the Income Tax Assessment Act 1997 can dramatically reduce or eliminate the tax payable on sale. These concessions are subject to eligibility tests — the most significant being that the business (or the business assets being sold) must meet the "small business entity" test (aggregated turnover below $2 million or net assets below $6 million), and the assets must satisfy the "active asset" conditions.
The 15-year exemption under Subdivision 152-B is the most powerful of the concessions. Where a business asset has been continuously owned for 15 or more years, and the owner is aged 55 or older at the time of the CGT event and is retiring (or permanently incapacitated), the entire capital gain can be exempt from CGT. No other test applies to the exemption amount itself — it removes the gain completely. The 50% active asset reduction under Subdivision 152-C halves the assessable gain on qualifying assets, independent of other concessions. The retirement exemption under Section 152-215 allows up to $500,000 of capital gain to be excluded from assessment in a lifetime — an amount that does not change with indexation — where the proceeds are either contributed to super or, for those under 55, retained and set aside for retirement purposes.
These concessions are technical and eligibility must be assessed against the specific facts of the sale. Business owners planning a sale should involve an accountant with Division 152 experience well in advance of the transaction.
What is the CGT cap and how does it allow super contributions beyond normal limits?
Where small business CGT concessions apply — particularly the 15-year exemption or the retirement exemption — proceeds can be contributed to superannuation under the CGT cap. This is a separate lifetime limit, currently $1.865 million for 2025-26, indexed annually. Contributions under the CGT cap do not count against the standard non-concessional or concessional contribution caps. For a business owner who qualifies for the 15-year exemption and has sale proceeds available to contribute, the CGT cap allows a substantial super injection well above the normal annual limits — potentially the single largest super contribution they will ever make.
The CGT cap contribution requires specific documentation and reporting, and the amount eligible for the cap is limited to the excluded gain under the concessions applied. An accountant and financial adviser working together in the sale year are essential to ensure the cap is used correctly.
Why is the business sale year the most important planning year for self-employed retirees?
For self-employed individuals with a saleable business, the year of business sale is often the most consequential planning year of their financial life. Business income typically drops materially in the sale year, creating a window for large concessional contributions at low marginal tax. The CGT concessions, if available, can eliminate or substantially reduce the gain. CGT cap contributions can move significant capital into superannuation outside the normal rules. Carry-forward concessional contributions can further accelerate the accumulation.
Done well, the combination of these tools in the sale year — timed to coincide with reduced income, with coordinated CGT concession claims, concessional contributions, and CGT cap contributions — can transform the super position going into retirement while producing a significantly lower tax outcome than an uncoordinated approach. For a business owner who has consistently under-contributed to super throughout their working life, this concentrated final-year effort can close much of the gap.
What super strategies apply to sole traders and freelancers without a saleable business?
For sole traders, contractors, and freelancers who don't have a business with independent value that a third party would purchase, the sale-year strategies don't apply. The path is narrower but still meaningful: personal deductible contributions up to the cap, carry-forward if eligible, and maximising the final high-income years before the income drops at retirement. For these individuals, the carry-forward provisions and coordinated concessional contributions in the five to ten years before retirement represent the primary accumulation window.
Key takeaways
- Self-employed individuals receive no automatic Superannuation Guarantee. Every dollar in their fund has been a deliberate choice, and many arrive at their fifties with balances that don't reflect the scale of what they've built — because most of what they've built sits in the business, not the fund. Late career is the high-leverage moment to address this gap.
- Personal deductible contributions are the primary super tool for the self-employed. Contributions are made from the individual's own bank account, a Notice of Intent to Claim a Deduction is lodged with the fund, and the deduction is claimed in the personal tax return. The contribution is taxed at 15% inside the fund rather than the higher marginal rate on business income. The concessional cap is $30,000 for 2025-26. A work test applies for ages 67 to 74.
- Carry-forward concessional contributions allow those with total super balance below $500,000 at 30 June 2025 to use unused cap from the prior five financial years — potentially well over $100,000 in a single year. For a self-employed individual in a high-income year with a below-threshold balance, combining the standard cap with carry-forward is one of the most tax-effective uses of available business income.
- Business owners may qualify for small business CGT concessions (Division 152, ITAA 1997) on business sale. The 15-year exemption eliminates the entire capital gain for owners aged 55 or older who are retiring after 15 years of continuous ownership. The retirement exemption excludes up to $500,000 lifetime. The 50% active asset reduction halves the assessable gain. Eligibility depends on the small business entity test and active asset conditions.
- Where CGT concessions apply, eligible proceeds can be contributed to super under the CGT cap ($1.865 million in 2025-26), outside the standard concessional and non-concessional limits. The year of business sale is often the most consequential planning year in a self-employed person's financial life — combining reduced income, CGT concessions, and the CGT cap can transform the retirement super position while producing a substantially lower tax outcome.
Frequently asked questions
Can self-employed people make concessional super contributions?
Yes — self-employed individuals can make personal deductible contributions directly from their own bank account to their super fund. These are concessional contributions, taxed at 15% inside the fund rather than at the individual's marginal income tax rate. To claim the deduction, a Notice of Intent to Claim a Deduction (ATO form NAT 71121) must be lodged with the fund and acknowledged in writing before the earlier of the tax return lodgement date or 30 June of the following financial year. The concessional cap is $30,000 for 2025-26. For those aged 67 to 74, a work test applies.
What is the Notice of Intent to Claim a Deduction for super?
The Notice of Intent to Claim a Deduction is the formal document (ATO form NAT 71121) that a self-employed individual must lodge with their super fund to convert a personal contribution into a concessional (deductible) contribution. The fund must acknowledge the notice in writing before the individual can include the deduction in their tax return. Timing is critical: the notice must be lodged before the earlier of the date the tax return is lodged or 30 June of the year following the contribution. If the notice is missed, the contribution remains non-concessional and is not deductible.
What are carry-forward concessional contributions and who qualifies?
Carry-forward concessional contributions allow eligible individuals to use unused concessional cap from the prior five financial years in addition to the current year cap. To qualify, total super balance must have been below $500,000 at 30 June of the year before the contribution — for 2025-26 contributions, the relevant date is 30 June 2025. The unused cap accumulates from 2019-20 onwards. A self-employed individual who has made minimal contributions for several years and has a below-threshold balance may be able to make a concessional contribution of well over $100,000 in a single high-income year.
What CGT concessions can apply when a self-employed person sells their business?
Division 152 of the ITAA 1997 contains four main small business CGT concessions, subject to eligibility. The 15-year exemption (Subdivision 152-B) exempts the entire capital gain where the asset has been owned continuously for 15 or more years and the owner is aged 55 or older and retiring — no tax on the gain at all. The retirement exemption (Section 152-215) excludes up to $500,000 of lifetime gain, with proceeds eligible for super contribution. The 50% active asset reduction (Subdivision 152-C) halves the assessable gain on qualifying assets. Eligibility requires meeting the small business entity test (aggregated turnover below $2 million or net assets below $6 million) and the active asset conditions. Specialist accounting advice is essential before any business sale.
What is the CGT cap for super contributions and how does it work?
The CGT cap is a separate lifetime limit that allows eligible amounts from small business CGT concessions to be contributed to superannuation outside the normal concessional and non-concessional caps. The cap is $1.865 million for 2025-26, indexed annually. Where the 15-year exemption or retirement exemption applies, the exempt or excluded gain amount can be contributed to super under the CGT cap without counting against the $30,000 concessional cap or the $120,000 non-concessional cap. The contribution requires specific ATO reporting and documentation, and the amount eligible is limited to the excluded gain under the relevant concession. For a business owner qualifying for the 15-year exemption with substantial sale proceeds, the CGT cap can facilitate the single largest super contribution they will ever make.
