Super for Self-Employed Australians: How to Contribute and Why You Should
Self-employed Australians have no employer paying SGC — but they can claim super contributions as a tax deduction and access the same concessional cap. Here's how it works.
If you're self-employed — sole trader, contractor, freelancer, or small business owner — no one is paying super on your behalf. There's no employer making SGC contributions. Your superannuation balance only grows if you actively contribute.
The good news: self-employed Australians can claim super contributions as a tax deduction, access the same concessional cap as employees, and use carry-forward rules to catch up on missed years. The maths is compelling — a $30,000 contribution can save you $4,500–$9,600 in tax depending on your income.
The difference for self-employed vs employees
| Employee | Self-employed | |
|---|---|---|
| Employer super contributions | Yes — 12% SGC mandatory | No automatic contributions |
| Who funds super | Employer pays into super | You pay from business income |
| Tax deductibility | Employer deducts it; you benefit from lower salary | You claim deduction directly in tax return |
| Concessional cap | $32,500 total (employer + salary sacrifice) | $32,500 total (personal contributions) |
| Carry-forward rules | Same | Same (TSB must be < $500,000) |
Self-employed people can contribute up to the full $32,500 concessional cap themselves. The entire amount can be a personal deductible contribution if you complete the right paperwork.
How to claim the deduction: the Notice of Intent
The mechanism that makes self-employed super contributions deductible is the Notice of Intent to Claim a Deduction (ATO form s290-170 / NAT 71121).
Process:
- Make a personal contribution to your super fund (deposit funds directly into your super account)
- Before the earlier of: lodging your tax return OR 30 June of the following financial year — submit the Notice of Intent to your super fund
- The super fund acknowledges the notice
- You claim the deduction in your tax return
Without the Notice of Intent, the contribution is treated as non-concessional (after-tax) — you don't get the deduction.
Important timing rule: The notice must be submitted before you lodge your tax return. If you lodge on 15 July and forget to submit the notice, you've lost the deduction for that amount. Do the notice first.
How much tax does a personal deductible contribution save?
Self-employed contributions are taxed at 15% inside the fund (contributions tax). You deduct them at your marginal rate. The saving is the difference.
| Taxable income (2026-27) | Marginal rate | + Medicare | Saving per $10,000 contributed |
|---|---|---|---|
| $45,001 – $135,000 | 30% | 32% | $1,700 |
| $135,001 – $190,000 | 37% | 39% | $2,400 |
| $190,001 – $250,000 | 45% | 47% | $3,200 |
| $250,001+ (Div 293) | 45% | 47% | $1,700 (after Div 293) |
Worked example — sole trader earning $120,000:
Tax without super contribution: taxable income $120,000 Tax with $20,000 super contribution: taxable income reduced to $100,000
| Without | With $20k super | |
|---|---|---|
| Taxable income | $120,000 | $100,000 |
| Income tax + Medicare | ~$28,920 | ~$22,520 |
| Super contributions tax (15%) | — | $3,000 |
| Total tax | $28,920 | $25,520 |
| Net saving | — | $3,400 |
And the $20,000 is now growing in super for retirement — a genuine retirement asset created with tax-advantaged dollars.

The $32,500 concessional cap for 2026-27
From 1 July 2026, the concessional contributions cap is $32,500 per year. Self-employed people can contribute up to this amount in personal deductible contributions.
For high-income self-employed individuals, the Division 293 threshold of $250,000 means that if your taxable income plus contributions exceeds $250,000, an additional 15% tax applies on the excess — making the effective super tax 30% instead of 15%. The saving is still significant at 17% (47% − 30%), but less dramatic than for lower earners.
Carry-forward contributions: catching up on lean years
If you've had low-income years (starting a business, parental leave, slow periods) and your total super balance (TSB) was under $500,000 on 30 June of the prior year, you can use carry-forward to contribute more than the standard $32,500 cap in a high-income year.
Unused cap amounts from the past 5 years (from 2019-20 onward) can be used.
Example: A freelancer who contributed only $8,000/year for the past 4 years (instead of the full cap) has accumulated approximately $80,000–$88,000 of unused cap. In a particularly high-income year, they could potentially contribute $32,500 + unused carry-forward amounts (up to the accumulated total) in a single year, generating a significant tax deduction.
This is one of the most powerful tools available to self-employed people with irregular income — bank unused cap in bad years, deploy it in good ones.
What type of super fund suits self-employed people?
Industry fund or retail fund: Simple, low-cost, minimal administration. The standard choice for most self-employed people. Just make contributions directly and submit the Notice of Intent.
Self-Managed Super Fund (SMSF): SMSF has greater investment flexibility (can hold unlisted assets, direct property) but involves trustee responsibilities, annual audits, and fixed costs that only make sense above approximately $250,000–$500,000 in balance. Most sole traders starting out should use a standard fund first.
Things to check in your fund:
- Can you make personal contributions easily (BPay, bank transfer)? Most modern funds can.
- Does the fund allow personal deductible contributions? All regulated super funds must accept them up to the cap.
- What investment options are available? A low-fee balanced or growth index option suits most long-term super investors.
Super obligations if you have employees
If you're self-employed and you employ staff, you must pay 12% SGC on their ordinary time earnings by the relevant quarterly due dates. This applies to employees earning more than $450/month (threshold has been removed — SGC now applies to all employees regardless of income).
Missing SGC payments triggers the Superannuation Guarantee Charge (SGC charge) — a penalty on top of the unpaid super. The ATO has significantly increased enforcement in recent years.
Your own super as the business owner is still your responsibility to fund separately — being an employer doesn't automatically fund your personal super.
When to make contributions
Timing options:
- Regular contributions throughout the year — lump sum monthly or quarterly. This matches income timing and avoids the year-end scramble.
- Lump sum before 30 June — common for business owners who don't know final income until late in the year. Must clear your super fund by 30 June.
- After lodging BAS for the quarter — matches cashflow for GST-registered businesses
One critical timing rule: The contribution must be received by your super fund by 30 June to be deductible in that financial year. Don't leave it to 29 June — allow several business days for processing.
Frequently asked questions
Do self-employed Australians have to pay superannuation?
Self-employed people (sole traders, contractors, partners) are not required to pay themselves super under the Superannuation Guarantee. However, many choose to voluntarily contribute for retirement savings. If you have employees, you must pay them SGC as normal. Some contractors engaged through labour hire may be entitled to SGC — the rules depend on the employment structure.
How do I claim a tax deduction for super contributions as a self-employed person?
Make a personal contribution to your super fund, then submit a Notice of Intent to Claim a Deduction (form s290-170) to the fund before you lodge your tax return. The fund acknowledges the notice, and you claim the deduction in your tax return. Without the notice, the contribution is treated as non-concessional and is not deductible.
How much can I contribute to super as self-employed in 2026-27?
Up to the concessional contributions cap of $32,500 in personal deductible contributions. If you have unused cap from prior years and your TSB was under $500,000 on 30 June 2026, you may be able to contribute more via carry-forward rules. You can also make additional non-concessional (after-tax) contributions up to the $130,000 NCC cap.
Can I contribute to super and still have a business?
Yes — super contributions reduce your taxable business income (as personal deductible contributions). The business itself is separate from your personal super fund. If you operate through a company, the company can also make employer super contributions on your behalf (as employee), which are a business expense for the company and taxed at 15% inside the fund.
What happens if I contribute more than the concessional cap?
Excess concessional contributions are added to your assessable income and taxed at your marginal rate, with a 15% tax offset for the contributions tax already paid. The ATO automatically identifies excesses from fund reporting data and issues an excess concessional contributions tax assessment. Always track your contributions throughout the year to avoid breaching the cap.
