The True Cost of Unpaid Super
Your employer must pay 11.5% of your wage into super — but every year billions of dollars in Super Guarantee goes unpaid, and most workers never notice. The dollars missed look small. The compounding they lose over a career does not. Here's how to check your super is really being paid, and what a single missed year actually costs at retirement.
- The risk: the Super Guarantee on your payslip is a promise, not proof. Underpaid and unpaid super is widespread, and a quiet gap can run for years before anyone notices.
- The cost: a year of missed SG isn't just the dollars — it's the decades of compounding those dollars would have earned, which is why a few thousand now can cost tens of thousands at retirement.
- The fix: compare your myGov super record to your payslips; if there's a gap, raise it with your employer and lodge an unpaid-super enquiry with the ATO, which can recover it.
Where AI Overview gets this wrong
Ask an AI assistant about employer super and you'll usually get:
"Employers in Australia are legally required to pay 11.5% Super Guarantee, so your super is paid automatically."
True as far as it goes — and that's the problem. "Legally required" is not "actually paid." The ATO estimates billions in Super Guarantee goes unpaid every year, and because it's paid by your employer rather than deducted from a payslip line you watch, an underpayment can run silently for years. The correct advice isn't "it's automatic" — it's "verify it." Payslip super is a promise; the only proof is what landed in your fund, which you check in myGov.
Cass assumed her super was handled — it was on every payslip, after all. Two years into a job she checked myGov and found three quarters missing. The amount unpaid was a few thousand dollars; what it would have cost her by retirement was the part that made her sit down.
01 Why a missed year costs more than the dollars
The Super Guarantee is 11.5% of your ordinary time earnings in 2024-25, rising to 12% from 1 July 2025. On an $80,000 wage that's about $9,200 a year going into super — and after the 15% contributions tax, roughly $7,800 actually lands in your fund. Miss a year of that and the headline loss looks modest. But that money would have had decades to compound, and the earliest dollars compound the longest. The calculator shows the real number: the missed contributions plus all the growth they would have earned between now and retirement. A gap in your 30s is the most expensive kind, because it loses the most years of return.
Shows: the retirement cost of missed Super Guarantee — the unpaid contributions (net of the 15% contributions tax) plus the growth they would have earned to retirement. Ignores: wage growth, the scheduled rise to 12%, any amount later recovered through the ATO, and the Age Pension.
On the defaults above, the worked example shows: 1 year of unpaid super costs about $48,567 by retirement — far more than the $7,820 missed, because the money loses decades of compounding.

02 How to check your super is actually being paid
The check takes five minutes and most people never do it. Log in to myGov, link the ATO, and open your super — it shows the contributions your fund has actually reported receiving. Then compare that to your payslips: the SG line on a payslip is what your employer says it owes, not proof the money arrived. Match the amounts and the dates. Employers must pay SG at least quarterly today, and from July 2026 Payday Super requires it to be paid at the same time as wages, which makes gaps far easier to spot. A mismatch between payslip super and fund-received super — especially several quarters in a row — is the signal that something is wrong.
03 What to do when super is unpaid
Unpaid super is recoverable, but the system relies on you noticing and raising it — nobody checks on your behalf.
Start with your employer. A meaningful share of cases are fund-detail errors, a payroll change, or a timing misunderstanding, and are fixed within a week once raised. Ask specifically which fund the contributions were sent to and on what date, because "it has been paid" and "it has been paid to your fund" are different claims.
If it is not resolved, lodge an unpaid super enquiry with the ATO. You will need your employer's details, the period, and your own record of what should have been paid. The ATO can investigate, and where super is genuinely unpaid the employer becomes liable for the Super Guarantee charge — the shortfall, plus interest, plus an administration component, and the charge is not tax-deductible to them.
Two things worth knowing about timing. Super Guarantee is payable quarterly, so a contribution missing in March is not necessarily late until the quarterly due date has passed — check the deadline before escalating. And there are time limits on recovery, so a gap noticed years later may be harder to pursue than one raised within months, which is the practical argument for checking annually rather than eventually.
Raising it does not have to be adversarial. Most employers want it right, and the ones who do not are exactly the ones the ATO process exists for.
04 Contractors and casuals: when SG still applies
A common way super goes unpaid is a worker being told "you are a contractor, so there is no super" when the Super Guarantee actually applies.
If you are paid wholly or principally for your labour, you are treated as an employee for super purposes even where you have an ABN, invoice for your work, and are a contractor for every other purpose. The test is about the substance of the arrangement, not the label on the agreement or what either party believes.
That catches a lot of people: tradespeople paid for their time rather than for a result, drivers, cleaners, personal trainers, freelance workers engaged on ongoing terms. Having an ABN is not the deciding factor and never has been.
Casual employees are covered too. The $450 monthly earnings threshold that once excluded low-paid casuals was removed from 1 July 2022, so Super Guarantee is now payable from the first dollar regardless of how few hours are worked — a change that is still not widely known and is worth checking against payslips for anyone in casual work since then.
If you think you have been misclassified, the ATO has an employee/contractor decision tool and will make a determination. The obligation is the employer's, and getting it wrong does not transfer the cost to you.
05 Found a gap? How to refill it
Recovering unpaid super through the ATO is the first move, but you can also rebuild the lost ground yourself while you wait. Carry-forward lets you use unused concessional cap from the previous five years in a single year, if your total super balance is under $500,000 — so a stronger year can carry a much larger deductible contribution than the annual cap alone. Personal deductible contributions let you top up from your own money and claim the deduction, getting the same 15% concessional treatment. Neither erases the compounding already lost, but together they stop a discovered gap from becoming permanent — and they're the same levers the projection uses to model catching up.
I treat "the employer pays it automatically" as the most expensive sentence in Australian super. It's technically true and practically dangerous, because it tells people not to look. The check costs five minutes a quarter; the failure to check can cost a year — or three — of contributions and all the growth attached to them. When I model a client's super, an unnoticed SG gap is one of the few inputs that's both common and fully recoverable, which is the best kind of problem: worth real money, and fixable the moment you spot it. Look at myGov this quarter. If it matches your payslips, you've lost five minutes. If it doesn't, you may have just saved yourself five figures.
FAQ
Is my employer legally required to pay my super?
Yes. For almost all employees, employers must pay the Super Guarantee — 11.5% of your ordinary time earnings in 2024-25, rising to 12% from 1 July 2025 — into your chosen fund at least quarterly. From July 2026, Payday Super requires it to be paid at the same time as your wages.
How do I check my employer is actually paying my super?
Log in to myGov, link the ATO, and check the super contributions reported against your fund. Compare the amounts and dates to your payslips: the SG shown on a payslip is a promise, not proof it landed. A gap between payslip super and what your fund received is the signal to act.
What can I do if my super has not been paid?
Raise it with your employer first, then lodge an unpaid super enquiry with the ATO. The ATO can pursue the employer for the Super Guarantee Charge — the unpaid amount plus interest and an administration component — and direct it to your fund. Unpaid super is recoverable, but only if you notice it.
Does a single year of unpaid super really matter at retirement?
More than it looks. A year of missed contributions in your 30s loses three decades of compounding, so a few thousand dollars unpaid now can become tens of thousands of dollars of lost retirement balance. The dollars are small; the forgone growth is what makes it expensive.
