The Contract Says Contractor and the Law May Not Agree
Superannuation Guarantee obligations follow the substance of a working arrangement rather than the label on it. A contractor engaged wholly or principally for their labour is an employee for superannuation purposes, and the person paying them owes contributions — regardless of what the contract says, whether an ABN was quoted, or whether an invoice was issued.
- The answer: A contract wholly or principally for a person's labour attracts Superannuation Guarantee, and the person doing the work is treated as an employee for that purpose.
- The trap: Quoting an ABN does not change the answer. Neither does invoicing, a written contract describing you as a contractor, or being paid a fixed fee.
- The recommendation: Use the ATO's employee-or-contractor tool before assuming. Where super is owed and has not been paid, the recovery route is the same as for any unpaid super.
Where the AI summary above gets this wrong
"Contractors are responsible for their own superannuation."
That's surface-true. Here's what it misses:
- Many contractors are employees for super purposes — Where the contract is wholly or principally for the person's labour, the payer owes Superannuation Guarantee even though the worker invoices and holds an ABN.
- The test is about the substance of the arrangement — It looks at whether the person is paid for a result or for their time, whether they can delegate the work, and who bears the commercial risk.
01 The labour test
Superannuation law extends the meaning of employee to a person working under a contract that is wholly or principally for their labour. Three things generally have to hold: the contract is with the individual rather than a company, they are paid for their labour rather than for a result, and they cannot delegate the work.
Where a contract is with a company, trust or partnership rather than with the individual, the obligation generally does not arise. That is why so many arrangements are structured that way, and it is a real distinction rather than a formality.
The ability to delegate is the factor that most often decides it. Someone who must personally perform the work is on the employee side of the line; someone who can send a substitute is not.

02 What being wrong costs
Where super was owed and not paid, the payer becomes liable for the superannuation guarantee charge, which includes the shortfall, interest and an administration component, and is not deductible.
For the worker, the loss is the contributions and everything they would have earned. Over a decade of contracting that is a substantial balance, and the worked example puts a number on it.
Recovery runs through the ATO in the same way as any unpaid super, described in the unpaid super post. The claim can be made after the arrangement has ended, within the applicable periods.
Shows: the super a contractor would have accumulated if Superannuation Guarantee had been paid on their contract income, compounded over the years worked. Ignores: the superannuation guarantee charge that would be payable by the engager, fees inside the fund, contributions tax, and the maximum contributions base.
03 If you are genuinely self-employed
A genuinely self-employed person has no compulsory super and has to contribute deliberately. Nothing arrives automatically, and the retirement outcome for the self-employed is materially worse on average as a result.
Personal deductible contributions are the route, with the notice of intent requirement described in the contribution routes post. The deduction makes the contribution equivalent to salary sacrifice for someone with no employer.
Building it into the pricing rather than treating it as a leftover is what makes it happen. A contractor rate that does not include a super component is a rate below the equivalent employee cost, which is worth knowing when setting it.
The ABN does not settle it and the contract does not settle it. What settles it is whether you are being paid for your time and whether you could send someone else. Plenty of long-term contractors are employees for super purposes and have been for years, and the balance at stake over a decade is not small.
FAQ
Do I have to pay the Superannuation Guarantee for myself when I work as a contractor?
Not if you are genuinely self-employed — contributions are voluntary and made as personal deductible contributions. But where your contract is wholly or principally for your labour, the person paying you owes Superannuation Guarantee even though you invoice and hold an ABN.
Does having an ABN mean I am a contractor for super purposes?
No. The test looks at the substance of the arrangement: whether the contract is with you personally, whether you are paid for your labour or for a result, and whether you can delegate the work.
What if super should have been paid and was not?
The payer becomes liable for the superannuation guarantee charge, which includes the shortfall, interest and an administration component. The recovery route runs through the ATO and a claim can be made after the arrangement has ended.
