Sole traders don’t have to pay superannuation for themselves, because you and your business are the same legal entity and you can’t be your own employee.1Australian Taxation Office. Super for Sole Traders and Partnerships You do have to pay super the moment you take on staff, and often when you engage contractors, at the current rate of 12% of their earnings.2Australian Taxation Office. Super Guarantee So the answer to “do sole traders have to pay super” splits in two: never for yourself, almost always for the people who work for you.
Super for Your Own Retirement Is Optional
There is no employer-employee relationship inside a sole trader business, so the super guarantee doesn’t apply to your own drawings.1Australian Taxation Office. Super for Sole Traders and Partnerships The ATO isn’t going to chase you if you skip it. The catch is that nobody else is putting money in either, so a decade of self-employment can leave a real hole in your retirement balance.
Most sole traders bridge the gap with voluntary personal contributions to their own super fund. These are generally tax-deductible, which can meaningfully reduce your taxable income in a profitable year. To claim the deduction you must lodge a Notice of Intent to Claim or Vary a Deduction for Personal Super Contributions with your fund, and receive their written acknowledgment, before you lodge your tax return for that year.3Australian Taxation Office. Notice of Intent to Claim or Vary a Deduction for Personal Super Contributions Miss that step and you lose the deduction, even if the money is sitting in the fund.
Contribution Caps if You Do Pay Yourself Super
Concessional Contributions
For 2025–26, the concessional contributions cap is $30,000.4Australian Taxation Office. Contributions Caps Concessional contributions include any personal contributions you claim as a deduction. They’re taxed at 15% inside the fund rather than at your marginal rate, which is where the saving comes from. If your combined income and super contributions go over $250,000, an extra 15% Division 293 tax applies to the lesser of the excess or the contributions.5Australian Taxation Office. Division 293 Tax
Sole trader income is often uneven. If you’ve had lean years where you contributed little or nothing, the carry-forward rule is worth knowing. When your total super balance is below $500,000, you can carry unused concessional cap amounts from the previous five years into a single profitable year.6Australian Taxation Office. Concessional Contributions Cap It’s one of the most useful provisions in the system for self-employed people and is frequently overlooked.
Non-Concessional Contributions
The after-tax cap is $120,000 for 2025–26. You don’t get a deduction, but earnings inside super are taxed at a maximum of 15% rather than your marginal rate. If you’re under 75 and your total super balance was below $1.76 million at 30 June 2025, the bring-forward arrangement lets you contribute up to $360,000 in a single year by pulling forward two more years of cap space.7Australian Taxation Office. Non-Concessional Contributions Cap Going over either cap triggers extra tax, so track what you’ve paid in.
Government Co-Contribution
If your total income for 2025–26 is below $62,488, you may qualify for a government co-contribution of up to $500 when you make personal after-tax contributions.8Australian Taxation Office. Government Contributions The maximum applies at incomes of $47,488 or less and phases out from there. There’s one catch: if you claim a deduction for a personal contribution, that same contribution doesn’t qualify for the co-contribution.1Australian Taxation Office. Super for Sole Traders and Partnerships For lower-income sole traders, it’s worth running the numbers both ways.
When You Hire Staff, Super Becomes Mandatory
Once you employ anyone, you’re an employer for super purposes. The super guarantee rate is 12% of the employee’s ordinary time earnings, effective from 1 July 2025, and this is the final step in the legislated increase from 9.5%.2Australian Taxation Office. Super Guarantee
Almost every employee qualifies, whether they work full-time, part-time or casually, and there’s no minimum earnings threshold. The old $450-per-month rule was abolished in 2022. The one live exception: employees under 18 only qualify if they work more than 30 hours in a given week.9Australian Taxation Office. Work Out if You Have to Pay Super
Super is calculated on ordinary time earnings, not gross pay. Overtime is generally excluded when the employee’s ordinary hours are clearly set in their award or agreement, and payments like workers’ compensation while not working, employer-paid parental leave, and unused leave paid on termination also fall outside OTE.10Australian Taxation Office. List of Payments That Are Ordinary Time Earnings Regular salary, commissions earned during ordinary hours, and most allowances are included. The ATO publishes a detailed payment-by-payment table when you need to check a specific line item.
From 1 July 2026 the calculation base shifts from OTE to a broader concept called qualifying earnings, which includes salary sacrifice amounts on top of OTE.11Australian Taxation Office. About Payday Super If any of your staff salary sacrifice into super, that change will affect what you owe.
When Contractors Count as Employees for Super
Having an ABN doesn’t automatically exempt a contractor from your super obligations. You must pay super for a contractor if the contract is mainly for their personal labour and skills rather than for a specific result.12Australian Taxation Office. Super for Independent Contractors
The ATO looks at three things:
- More than half the dollar value of the contract is for the person’s labour, rather than materials or equipment.
- The contractor must do the work themselves and can’t delegate it to someone else.
- The contract isn’t for a defined deliverable, like building a fence or writing a report, but for ongoing labour.
When all three point to a labour-based arrangement, you owe super at the same 12% rate as for employees.12Australian Taxation Office. Super for Independent Contractors A cleaner who comes every week using your supplies is probably super-eligible. Someone hired to paint a mural for a fixed price probably isn’t. If an arrangement is ambiguous, review it early, because back-paying years of missed super costs far more than getting it right up front.
Payday Super Changes How and When You Pay From 1 July 2026
From 1 July 2026, employers must pay super at the same time they pay salary or wages, and the contribution must reach the employee’s fund within seven business days of payday.11Australian Taxation Office. About Payday Super The old quarterly system, with payments due by the 28th of the month after each quarter, is gone for any pay periods from that date onward.13Fair Work Ombudsman. Payday Super: New Rules Starting 1 July 2026
If you pay staff weekly, super becomes weekly. Fortnightly pay means fortnightly super. There is a small grace period for new hires: the first super contribution for a new employee must be made within 20 business days of their first payday rather than seven.13Fair Work Ombudsman. Payday Super: New Rules Starting 1 July 2026
The Small Business Clearing House Is Closing
The ATO’s free Small Business Superannuation Clearing House permanently closes on 1 July 2026 and cannot be used after that date.14Australian Taxation Office. SuperStream for Employers If you use it now, you’ll need to move to payroll software with built-in super payment features, a commercial clearing house, or a payment service offered by your default super fund.15Australian Taxation Office. How to Transition From the Small Business Superannuation Clearing House The ATO’s SuperStream Product Register lists compliant providers. Don’t leave the switch to the last minute.
Reporting Under Payday Super
Employers must report both qualifying earnings and super liability through Single Touch Payroll each pay cycle.11Australian Taxation Office. About Payday Super Super payments still need to meet the SuperStream electronic standard, which requires data and money to be sent electronically in a prescribed format.14Australian Taxation Office. SuperStream for Employers Most modern payroll software handles both in one workflow.
What Happens if You Pay Super Late
Paying super late, or into the wrong fund, triggers the super guarantee charge. It’s always more expensive than the super you should have paid, and unlike ordinary super contributions, the SGC is not tax-deductible.16Australian Taxation Office. The Super Guarantee Charge
Under the current system, before 1 July 2026, the SGC has three components:
- The shortfall amount, calculated on total salary and wages including overtime rather than just OTE.
- Nominal interest of 10% per annum, accruing from the start of the relevant quarter.
- An administration fee of $20 per employee, per quarter.16Australian Taxation Office. The Super Guarantee Charge
From 1 July 2026, the penalty structure tightens. The SGC will be assessed by the ATO rather than self-assessed, interest compounds daily at the general interest charge rate, and additional penalties of 25% or 50% of the unpaid SGC apply depending on whether you’ve had prior penalties.11Australian Taxation Office. About Payday Super With payment due every pay cycle rather than quarterly, a missed payment can turn into a serious liability in weeks rather than months. Getting the process right from your first payday is the only realistic strategy.
