Super for Self-Employed Australians

No Compulsory Super for the Self-Employed

If you are self-employed, you do not receive compulsory Superannuation Guarantee contributions from an employer. This means building retirement savings is entirely your responsibility. Many self-employed Australians overlook super because cash flow is irregular and other business expenses take priority. However, super offers significant tax advantages that can benefit business owners who make regular contributions.

The Super Guarantee rate reached 12% on 1 July 2025, but this only applies to employees. As a sole trader, contractor, or business owner, you need to consciously decide to contribute to super — nobody does it for you. Even small, regular contributions can grow substantially over time thanks to compound returns and the tax-effective environment inside super.

Making Voluntary Contributions

As a self-employed person, you can make personal deductible contributions to your super fund and claim a tax deduction for them. From 1 July 2025, the annual concessional contributions cap is $30,000. This cap increases to $32,500 from 1 July 2026 due to indexation. You can also use unused cap amounts from previous years under the catch-up contribution rules if your total super balance is below $500,000. Non-concessional (after-tax) contributions are also available up to $120,000 per year (rising to $130,000 from 2026-27), or up to $360,000 under the bring-forward rule if you are under 75.

To claim a deduction, you must give your super fund a notice of intent in the approved form and receive written acknowledgment before lodging your tax return. The notice must be given by the earlier of the day you lodge your return or the end of the following income year. If you are 67 to 74 years old, you must also meet the work test (40 hours of work in a consecutive 30-day period during the year) to claim the deduction.

Example: How Deductible Contributions Save Tax

Suppose you are a sole trader with a taxable income of $90,000. You decide to contribute $15,000 to super and claim a deduction. Your assessable income reduces to $75,000, saving you approximately $4,125 in income tax (at the 34.5% marginal rate including Medicare). The $15,000 is taxed at 15% inside your super fund ($2,250) instead of your marginal rate. Over a working lifetime, this tax arbitrage can add tens of thousands of dollars to your retirement balance.

Tax Benefits

Personal deductible contributions are taxed at 15% within super — significantly lower than most self-employed people's marginal tax rate. Claiming the deduction reduces your assessable income for the financial year. This means you pay less income tax now while building retirement savings. The ATO requires you to lodge a notice of intent to claim a deduction with your super fund before lodging your tax return.

Government Co-Contribution

If your assessable income is below a certain threshold, you may be eligible for the government super co-contribution. For every dollar of after-tax contributions you make (up to $1,000), the government contributes up to 50 cents, capped at $500 per year. This is free money for your retirement — well worth claiming if your income is below the threshold. The lower your income, the higher the matching rate, so even a small after-tax contribution can yield a meaningful government boost.

Common Mistakes Self-Employed People Make

One common mistake is treating super as an afterthought. Unlike employees who receive compulsory SG contributions, self-employed people often prioritise reinvesting in their business over super. While reinvesting is important, delaying super contributions means losing years of compound growth. Another mistake is failing to lodge the notice of intent before the tax return deadline — if you miss this window, you cannot claim the deduction and the contribution becomes non-concessional instead. Finally, be aware of Division 293 tax: if your combined income and concessional super contributions exceed $250,000, you may pay an additional 15% tax on some or all of your concessional contributions.

Frequently Asked Questions

Can I claim a deduction for super contributions if my business made a loss?
Yes, but the deduction cannot create or increase a tax loss. You can only claim up to the amount of your assessable income for the year.

What happens if I exceed the concessional cap?
Excess concessional contributions are included in your assessable income and taxed at your marginal rate, plus an excess concessional contributions charge. You can elect to release up to 85% of the excess from super to help pay the tax.

Can I use my super to buy business property?
Through a Self-Managed Super Fund (SMSF), you may be able to purchase business premises and lease them back to your business, but strict rules apply around related-party transactions and market value rental. SMSF advice should only come from a qualified financial adviser.

Do I still need life insurance if I have super?
Yes. Holding insurance inside super can be cost-effective, but the level of cover through super alone may not be sufficient for self-employed people who do not have employer-provided income protection. Review your insurance needs separately from your super strategy.

What to Check in Your Advice Document

If your financial adviser has recommended a super strategy for your self-employed situation, your SOA, ROA, or CAR should address your business cash flow, contribution levels, the type of contributions recommended (concessional vs non-concessional), and how the strategy fits your retirement goals. If the document treats you like an employee receiving SG contributions, it may not be properly tailored. Look for evidence that your adviser considered your irregular income patterns, your ability to make catch-up contributions, and whether the government co-contribution is available to you.
