Superannuation for contractors in Australia works two ways. If a client hires you mainly for your personal labour, they must pay super on top of your fees at 12 percent of your ordinary time earnings for the 2025–26 financial year, even if you invoice through an ABN.1Australian Taxation Office. Super Guarantee If your arrangement falls outside that rule, no one is contributing for you and building a retirement balance is your responsibility, though the tax system offers real help along the way.
When a Client Has to Pay Super for You
The label on your contract doesn’t decide the question. Section 12(3) of the Superannuation Guarantee (Administration) Act 1992 treats a contractor as an employee for super purposes when three things are all true:2Australian Taxation Office. Super for Independent Contractors
- More than half the dollar value of the contract is for your personal labour, rather than for materials, equipment, or a finished product.
- You’re paid for your time and skills, not for a specified result at a fixed price.
- The contract requires you personally to do the work, with no right to delegate or subcontract.
All three have to be present. A tradesperson who supplies their own heavy machinery, or a contractor free to send in a substitute, generally falls outside. A graphic designer working a day rate on the client’s equipment, unable to hand the job to someone else, almost certainly falls inside.3Australian Taxation Office. TR 2023/4 The contract also has to be with you as a natural person; if you invoice through a trust or partnership, the rule doesn’t apply.
When you do qualify, the client calculates super on the labour portion of the contract, not the full contract price. On a $10,000 contract where $7,000 represents your labour, super is worked out on the $7,000.4Australian Taxation Office. Superannuation Guarantee Determination SGD 96/2
How Much and On What Earnings
The super guarantee rate for 2025–26 is 12 percent of ordinary time earnings, the final step in the annual increases that lifted it from 9.5 percent in 2020–21. There’s a quarterly ceiling: super is only compulsory on the first $62,500 of earnings per quarter, capping the mandatory contribution at $7,500 per quarter.1Australian Taxation Office. Super Guarantee Earnings above that don’t attract a required contribution, though a client can pay more voluntarily.
When Payments Are Due
Until 30 June 2026, clients pay at least quarterly, with the money needing to reach your fund (not just leave the client’s account) by these dates:5Australian Taxation Office. Super Payment Due Dates
- Quarter 1 (July–September): due 28 October
- Quarter 2 (October–December): due 28 January
- Quarter 3 (January–March): due 28 April
- Quarter 4 (April–June): due 28 July
From 1 July 2026, payday super begins. Clients must pay your super at the same time as your wages, and the contribution must reach your fund within seven business days. First contributions for new engagements have a 20 business day window.6Fair Work Ombudsman. Payday Super: New Rules Starting 1 July 2026 For contractors, the practical effect is that shortfalls become visible in near-real time instead of surfacing months later.
What Happens If a Client Doesn’t Pay
A client who misses the deadline owes the superannuation guarantee charge (SGC), which is designed to cost more than paying on time. Under the current quarterly system, the SGC bundles the shortfall, nominal interest at 10 percent per annum running from the first day of the quarter, and an administration fee. The SGC is calculated on total salary and wages rather than ordinary time earnings, so it always exceeds the original obligation.7Australian Taxation Office. The Quarterly Super Guarantee Charge From 1 July 2026, the interest component is replaced by notional earnings based on the general interest charge rate, compounded daily until the shortfall is fixed or the ATO issues an assessment.8Australian Taxation Office. The New Super Guarantee Charge Further penalties can stack for false statements or late lodgment, running up to 200 percent of the SGC in some cases.9Australian Taxation Office. Super Guarantee Penalties
How to Report Unpaid Super
You can report missing or underpaid super to the ATO once the quarterly due date for the period has passed.10Australian Taxation Office. Report Unpaid Super Contributions From Your Employer Before you lodge, the ATO suggests running its eligibility tool to confirm you’re entitled, estimating what should have been paid, then checking against what your fund actually received (either by phoning your fund or looking at ATO online services through myGov). Sometimes a shortfall turns out to be an administrative error a quick conversation with the client can fix.
When you’re ready to lodge, you’ll need your tax file number, the relevant period, and the client’s ABN. The ATO will ask whether they can use your name when contacting the client. If you’d prefer to stay anonymous, you can submit a tip-off through the ATO app or by calling 1800 060 062.10Australian Taxation Office. Report Unpaid Super Contributions From Your Employer
Building Your Own Super as a Sole Trader
If you don’t meet the employee test, no client will contribute for you. The trade-off is complete control over how much goes in and how it’s taxed.
Concessional Contributions
Concessional contributions come out of pre-tax income and are taxed at 15 percent inside the fund, usually well below your marginal rate.11Australian Taxation Office. Understanding Concessional and Non-Concessional Contributions The cap for 2025–26 is $30,000. If you didn’t use your full cap in earlier years and your total super balance was under $500,000 at the preceding 30 June, you can carry forward unused amounts from up to five prior years and make a larger deductible contribution now.12Australian Taxation Office. Contributions Caps For a sole trader whose income swings from year to year, a strong year is a chance to catch up.
Non-Concessional Contributions
Non-concessional contributions come from after-tax income. They don’t produce a deduction, but the money grows tax-free inside the fund and isn’t taxed again on withdrawal in retirement. The cap for 2025–26 is $120,000. Going over either cap triggers additional tax, so tracking contributions across every fund you hold matters.
Work Test for Older Contractors
Contractors aged 67 to 74 who want to claim a deduction for personal concessional contributions must satisfy a work test: at least 40 hours of gainful employment within a consecutive 30-day period during the relevant financial year. A work test exemption may also be available. Once you turn 75, funds generally can’t accept voluntary contributions.13Australian Taxation Office. Restrictions on Voluntary Contributions
Claiming the Deduction: Notice of Intent
Making a personal concessional contribution is only half the job. To claim the deduction, you must lodge a “Notice of intent to claim a deduction for personal super contributions” (form NAT 71121) with your fund and receive an acknowledgement before you lodge your tax return for that year.14Australian Taxation Office. Notice of Intent to Claim a Deduction The deadline is whichever comes first: the day you lodge your return, or the end of the following financial year. Miss it and the deduction is gone.
The notice must include your name, date of birth, fund details, the financial year of the contributions, the total contributed, and the amount you plan to claim. Your fund may have its own form, or you can write a letter with the same information.
Government Top-Ups for Lower-Earning Contractors
Two programs are applied automatically when you lodge your return, with no separate claim needed.
Super Co-Contribution
If your total income for 2025–26 is below $62,488 and you make a personal non-concessional contribution, the government matches 50 cents per dollar up to a maximum of $500. The full $500 is available up to $47,488 of income, then phases out as income rises toward $62,488.15Australian Taxation Office. Government Contributions You also need a total super balance under the general transfer balance cap ($2 million for 2025–26) and to have stayed within your non-concessional cap.16Australian Taxation Office. Transfer Balance Cap Under these thresholds, a $1,000 after-tax contribution produces $500 back from the government.
Low Income Super Tax Offset
LISTO effectively refunds the 15 percent contributions tax on concessional contributions for individuals earning $37,000 or less, capped at $500 a year, paid straight into your super account. From 1 July 2027, the income threshold rises to $45,000 and the maximum to $810.17Australian Taxation Office. Low Income Superannuation Tax Offset (LISTO)
Giving Your Client Fund Details
When a client owes you super, give them a completed Superannuation Standard Choice Form (NAT 13080). You’ll need your fund’s name, its Unique Superannuation Identifier (USI), its ABN, and your member number — all shown on your annual statement or online portal.18Australian Taxation Office. Superannuation Standard Choice Form Provide your tax file number too. Without it, your fund must withhold an extra 32 percent on top of the standard 15 percent on concessional contributions, taxing your super at 47 percent. Supplying the TFN later lets the fund recover the extra tax, but only for contributions made in the three prior years; anything older is lost.19Australian Taxation Office. No TFN Supplied – Additional Income Tax
If you don’t submit a choice form, your client can’t simply pick a default fund. Since November 2021, they must ask the ATO for your “stapled” super fund, the existing account that follows you between engagements. For independent contractor arrangements where no Single Touch Payroll relationship exists, the client submits a written request through secure mail, attaching the signed contract and a completed Contractor stapled super fund request form (NAT 75404).20Australian Taxation Office. Stapled Super Funds for Employers
If you use a self-managed super fund, contributions arrive through SuperStream. You’ll need to give the client an electronic service address (ESA) along with the SMSF’s ABN, BSB, and bank account number.21Australian Taxation Office. Get an Electronic Service Address Wrong details are the most common reason SMSF contributions get rejected or delayed.
Downsizer Contributions Near Retirement
Contractors aged 55 or older who sell their home may contribute up to $300,000 from the sale proceeds into super as a one-off downsizer contribution. Each member of a couple can contribute $300,000, for a combined $600,000. The home must have been owned for at least 10 years, and the contribution has to be made within 90 days of settlement.22Australian Taxation Office. Downsizer Super Contributions Downsizer amounts don’t count against the concessional or non-concessional caps, and there’s no work test. For a sole trader with most of their wealth in property, it’s a way to move a large sum into super in one transaction.
Making Voluntary Payments and Checking They Land
If you’re self-employed and paying your own contributions, the Small Business Superannuation Clearing House is a free ATO service that lets you send money to multiple funds in one transaction. You can also transfer directly from your business account via BPAY or electronic transfer.5Australian Taxation Office. Super Payment Due Dates To count toward the current year’s cap and deduction, the contribution needs to be made before 30 June.
To confirm contributions have arrived, log into ATO online services through myGov, which shows every contribution reported across each of your funds.23Australian Taxation Office. Keeping Track of Your Super Online Cross-check against your fund’s statement, since ATO records lag behind money movements. Under the current quarterly rules, a missing payment isn’t a problem until the quarterly deadline passes. Once payday super starts in July 2026, that window closes to days rather than months.
