The super guarantee charge: what happens when super is paid late

How late super becomes the SGC

Paying super on time is an ordinary, tax-deductible business cost. The moment a deadline is missed, the law swaps that obligation for something deliberately worse — the superannuation guarantee charge. For quarters up to 30 June 2026, the SGC is made up of:

• The shortfall — calculated on the employee's total salary and wages, not just ordinary time earnings, so it's usually more than the super you originally owed;
• Nominal interest at 10% p.a. — running from the start of the quarter, not the due date;
• An administration fee of $20 per employee, per quarter.

And the sting: under these rules the SGC is not tax-deductible — unlike the super would have been if paid on time. A business that pays super one day late pays more, on a bigger base, with interest backdated, and gets no deduction.

SGC statements and due dates (quarters up to 30 June 2026)

Missing a quarterly deadline triggered a second obligation: lodging an SGC statement with the ATO by one month after the contribution due date — 28 November, 28 February, 28 May and 28 August for the four quarters. Lodging the statement is what tells the ATO about the shortfall and starts a payable SGC assessment.

Many employers never lodged them, either not knowing they existed or hoping to quietly catch up. That choice has consequences beyond penalties — it decides whether directors' personal exposure can ever be undone.

No grace period: why super debt locks down automatically

For BAS debts like PAYG withholding and GST, directors get a 3-month lodgment window that keeps a future director penalty notice in remittable, "non-lockdown" territory. Super has no such window. If the SGC statement wasn't lodged by its due date, the director penalty for that quarter is lockdown from day one: appointing an administrator, restructuring practitioner or liquidator does nothing — only payment in full removes the personal liability. The full comparison: lockdown vs non-lockdown DPNs.

This is why insolvency specialists almost always triage super debt first, even when it's the smallest number on the list.

Payday super: the rules changed on 1 July 2026

The payday super legislation received royal assent in November 2025 and started on 1 July 2026. For wages paid from that date:

• Super is due every payday. Contributions must arrive in the employee's fund within 7 business days of payment (with limited exceptions, such as new starters). The old quarterly due dates are gone.
• The SGC has been redesigned. There are no more quarterly SGC statements — the ATO assesses the new SG charge itself, using Single Touch Payroll and fund data. The charge comprises the outstanding shortfall (now based on qualifying earnings), notional earnings compounding daily at the general interest charge rate, and an administrative uplift of up to 60% of the shortfall — reduced if you voluntarily disclose before the ATO comes to you.
• The new charge is tax-deductible — a genuine improvement on the old regime — but late-payment penalties (25% of unpaid SGC, rising to 50% for repeat cases) and interest on unpaid charge amounts are not.
• Detection is near-immediate. With every payday reported through STP and funds reporting contributions received, a missed super payment is visible to the ATO within days.

Director penalty exposure for unpaid super continues under the new system. The practical takeaway: super non-payment used to surface quarterly; now it surfaces per pay run, with an automatic charge attached.

Why super should usually be paid first

When there isn't enough cash for every ATO debt, the order matters, and super generally goes to the front of the queue:

1. It's the only debt with automatic lockdown exposure — no lodgment window protects directors, and the liability survives liquidation of the company.
2. It grows uglier than other debts — interest from the start of the quarter, admin costs, penalties of up to 200% of the SGC in bad cases, and (for old quarters) no deduction for any of it.
3. Unpaid super blocks the exits. Eligibility for small business restructuring — the main tool for compromising ATO debt while trading on — requires employee entitlements including super to be paid. Super debt left too long can close off the very option that would have solved the rest.

Payment plans are possible for SGC (see ATO payment plans), but they don't remove director penalty exposure, and interest keeps running. If super debt is one strand of a bigger problem, start with what's my situation? or the wider guide to what happens when you can't pay.
