What Happens When Super Isn't Paid On Time
Superannuation guarantee (SG) contributions are due quarterly (or, under the newer payday super arrangements, alongside each pay run), and missing that deadline doesn't just mean paying late, it changes the entire nature of the obligation. Once a due date passes, the employer no longer simply owes the super, they owe the Superannuation Guarantee Charge (SGC), a separate and more expensive liability that the ATO administers directly.
The Superannuation Guarantee Charge Explained
The SGC isn't just the unpaid super with a bit added on, it's calculated differently and costs meaningfully more than paying on time would have.
| Component | What it is | Why it costs more than paying on time |
|---|---|---|
| SG shortfall | The unpaid super, calculated on total salary and wages (not just ordinary time earnings) | Can be higher than the original OTE-based liability would have been |
| Nominal interest | 10% per annum, calculated from the start of the relevant quarter until the SGC is paid | Accrues the whole time the shortfall remains unresolved |
| Administration fee | A flat $20 per employee, per quarter | Applies regardless of how small the shortfall is |
| Deductibility | The SGC is not tax-deductible | Unlike super paid on time, which is a normal deductible business expense |
How the ATO Finds Out
Single Touch Payroll (STP) gives the ATO close to real-time visibility of wages reported against super contributions actually received by super funds. This has meaningfully narrowed the gap where unpaid super used to go unnoticed for months or years, mismatches between STP-reported wages and super fund contribution data are now flagged far sooner than they once were.
The Penalty for Not Paying Super, and How It Escalates
The penalty for not paying super on time starts with the SGC itself, but it doesn't necessarily stop there. The penalties for not paying super can escalate significantly if the shortfall isn't addressed once identified.
| Stage | What triggers it | What it adds |
|---|---|---|
| SGC assessment | Super not paid by the quarterly due date | SG shortfall, 10% nominal interest, $20/employee admin fee, no deduction |
| Part 7 penalty | SGC statement not lodged voluntarily, or non-compliance during an ATO review | Up to an additional 200% of the SGC amount, at the Commissioner's discretion |
| Director Penalty Notice | Unpaid SGC not addressed | Personal liability for the company director, see our guide on director penalty notice payment plans |
| Garnishee or legal recovery | DPN and other recovery steps unresolved | Direct enforcement against business or personal assets |
Lodging an SGC statement voluntarily, before the ATO raises it through an audit or review, is one of the few levers available to reduce the Part 7 penalty component. Waiting for the ATO to find the shortfall first generally results in a far less favourable outcome than coming forward proactively.

Unpaid superannuation guarantee charge is one of the specific debts a Director Penalty Notice can be issued for, alongside PAYG withholding. If the SGC isn't reported and paid, the same lockdown and non-lockdown mechanics that apply to unpaid PAYG apply here too, meaning a director can become personally liable, sometimes with very limited options to remit that liability once three months pass without lodgement.
Fixing It Before It Escalates
The path back from an unpaid super position is straightforward in principle, even if it's uncomfortable in practice:
- Lodge the SGC statement voluntarily, rather than waiting to be caught, this materially affects how the Part 7 penalty is applied.
- Pay what can be paid immediately, and negotiate a payment plan for the balance, engaging early gives more room to negotiate.
- Fix the underlying payroll process, so the same shortfall doesn't recur next quarter, a one-off catch-up doesn't help if the system that caused it is still broken.
- Keep lodging on time going forward, even if payment needs to be staged, since non-lodgement is what turns a manageable debt into a lockdown DPN.
Paid Late vs SGC Applies vs DPN Issued
| Scenario | Cost | Tax deductible? | Director personal liability? |
|---|---|---|---|
| Paid on time | Super amount only | Yes | No |
| Paid late, before SGC assessed | Still generally treated as SGC once the due date has passed | No | Not yet, but exposure is rising |
| SGC assessed and unresolved | SG shortfall + 10% interest + $20/employee admin fee | No | Becomes possible if left unaddressed |
| DPN issued | Full SGC amount, potentially plus Part 7 penalty | No | Yes, personally liable director |
The Bottom Line
The penalties for not paying super are structured to make late payment noticeably more expensive than paying on time, on purpose, and STP has closed most of the gap where a shortfall used to go unnoticed. The single most protective habit is straightforward, reconcile super against wages every pay run, not just at BAS time, so a shortfall gets caught while it's still small and easy to fix.
