SGC penalties for late super under payday super

If super reaches a worker’s fund late under payday super, the employer can owe the super guarantee charge, daily notional earnings, a 60% administrative uplift and, after assessment, a further payment penalty.

The payday super deadline

Payday super applies to wages paid on or after 1 July 2026, as at August 2026. Instead of waiting for a quarterly contribution deadline, employers must send super after each payday.

The contribution generally needs to reach the employee’s super fund within 7 business days of payday, as at August 2026. Sending the payment file to your bank, payroll system or clearing house is not enough. The money must arrive at the fund.

That distinction matters on construction payrolls. Weekly wages, changing crews, allowances and off-cycle corrections create plenty of payment events. A Friday payroll followed by a failed fund payment can become an SG shortfall before anyone spots the rejection.

The SG rate is 12% of earnings that attract SG, as at August 2026. The rate alone does not show the full cost of being late. Once the deadline is missed, the super guarantee charge, or SGC, can add interest and an administrative uplift.

See our payday super hub for the wider rules on timing, payroll setup and contribution processing.

SGC is more than the missing super

The new SGC framework is intended to put the employee in the position they would have been in if super had arrived on time. It also adds an amount for administering the breach.

SGC component	What triggers it	What it can cost
SG shortfall	The required contribution does not reach the fund on time	The unpaid SG amount
Notional earnings	Super was unavailable to the employee’s fund from the due date	Interest calculated using the applicable general interest charge rate and compounded daily
Administrative uplift	An employer has an SG shortfall	60% of the SG shortfall, as at August 2026, before any available reduction or remission
Post-assessment interest	An assessed SGC debt remains unpaid	General interest charge on the unpaid tax debt
Additional payment penalty	Assessed SGC is not paid within the required period	Up to 50% of the unpaid SGC after 28 days, as at August 2026

The general interest charge rate changes over time. That means you should calculate notional earnings using the rate applying to the relevant days, rather than keeping one percentage in a payroll spreadsheet forever.

The 60% uplift may be reduced in circumstances covered by the law, including where an employer comes forward early. It should not be treated as an automatic discount. Waiting for the ATO to find the shortfall can leave the business in a worse position.

A simple late-super example

Say a civil construction worker is paid $10,000 of earnings that attract SG across several pay runs. At the 12% SG rate applying as at August 2026, the required super is $1,200.

If that $1,200 is not received by the fund on time, the starting SGC exposure may include:

• the $1,200 SG shortfall
• daily notional earnings from the relevant due date
• an administrative uplift initially calculated at 60%, which is $720
• further interest if an assessed amount is not paid
• a possible additional penalty if the assessment remains unpaid after 28 days.

So the issue is not fixed by saying, “We eventually paid the $1,200.” The late payment needs to be matched and treated under the SGC rules. The employer may also have reporting obligations.

A late contribution can be credited against a shortfall where the legal conditions are met. Do not assume the payroll system or clearing house will do this automatically.

Why construction employers are exposed

Construction payroll rarely sits still. Common risk points include:

Weekly and multiple pay runs

A weekly payroll creates about four or five super deadlines each month. An extra run for missed hours, site allowances or back pay may create another contribution obligation.

Rejected fund payments

A contribution can fail because member details are wrong, a super account has closed or a fund cannot match the worker. The payroll may be correct while the super is still late. Rejections need an owner, an alert and a quick correction process.

Allowance and overtime coding

Not every construction allowance is treated the same way for SG. The label in the payroll system does not decide the outcome. You need to check what the payment is for and whether it forms part of the employee’s earnings that attract SG.

The same goes for overtime, bonuses, leave payments and termination amounts. Review your award, enterprise agreement and employment terms, but remember that those documents cannot remove a statutory SG obligation.

Labour hire and worker classification

Calling someone a subcontractor does not settle their SG status. Some contractors are employees for SG purposes, particularly where the contract is mainly for their labour. A classification mistake can produce shortfalls across many paydays.

Cash-flow delays

Holding super until a progress claim is paid is not an option. The seven-business-day clock runs from the employee’s payday, not from the date the builder or client pays your invoice.

What to do when super is late

Start with the facts. Confirm the payday, the contribution amount, the date the fund received it and the reason for any rejection.

Then:

1. Correct fund or employee data immediately.
2. Send the outstanding contribution without waiting for the next normal cycle.
3. Identify every affected employee and payday.
4. Calculate the shortfall and daily notional earnings.
5. Check whether an SGC statement or other ATO disclosure is required.
6. Pay any assessed amount by its deadline.
7. Keep evidence of the correction and voluntary disclosure.

Use the payday super calculator to check contribution deadlines and model the effect of a late payment. It is a practical starting point, but a complicated shortfall may still need advice from your accountant, payroll adviser or tax lawyer.

Keep evidence that the fund received the money

A bank debit only proves that money left your account. Keep clearing-house reports, fund acceptance records, payment references and rejection notices. Reconcile them against each payroll run.

Your exception report should show contributions that are pending, rejected or unmatched. Check it before the seven-business-day period ends, not at month-end.

Also separate paydays before and after 1 July 2026. Earlier wages remain subject to the rules that applied before payday super. Do not push an old quarterly shortfall into a post-July payday batch and assume it has disappeared.

The practical rule is simple: pay early enough for the fund to receive the money, watch every rejection and act before the ATO has to ask.
