From 1 July 2026, when you’re required to pay your employees' superannuation will change. Under the new payday super rules, super guarantee (SG) contributions must reach your employees' funds within seven business days of each payday. With this much tighter window, knowing how to spot and fix a rejected contribution quickly is no longer optional: it's essential to avoid penalties.
The key change is speed. If a super fund rejects your contribution through SuperStream, it will generally need to allocate or return the payment within three business days. A rejection doesn’t by itself satisfy the seven-business-day receipt requirement; you need to resolve issues and resubmit in time for the fund to receive the contribution by the original due date, unless an extended timeframe applies.
Most rejections come down to data quality. The ATO and SuperStream identify incorrect fund details, unique superannuation identifiers (USIs), member numbers or tax file numbers (TFNs) as frequent culprits. Where contributions are processed outside SuperStream (which is rare), returned payments may arrive without error codes, making troubleshooting harder. Where SuperStream’s used (as is generally required for employer contributions), your clearing house or digital service provider should provide clearer error messaging from 1 July 2026 under the SuperStream v3 upgrade.
If a contribution bounces back, you should:
check the error message from your clearing house or digital service provider straight away;
review and correct employee data such as TFNs, names and fund details;
use a member verification request (MVR) to confirm fund details before resubmitting;
resubmit the contribution within the original seven business day window; and
if the stapled fund rejects the payment, follow ATO choice-of-fund rules and pay to an eligible alternative fund.
Extended 20-business-day timeframes apply in some specific circumstances, such as where you’re changing the fund you contribute to for an employee.
If the seven business day window closes before the contribution lands, the super guarantee charge (SGC) begins to apply. The SGC now includes the shortfall, daily compounding notional earnings, and an administrative uplift amount of up to 60% (subject to reductions for voluntary disclosure). The good news is the SGC is tax deductible from 1 July 2026 (although penalty and ATO general interest charges on unpaid amounts remain non-deductible).
You should still pay the late contribution directly to the employee's super fund before the ATO issues an assessment, as this can reduce (but not eliminate) the SGC. A voluntary disclosure made within 30 days of the qualifying earnings day can reduce the administrative uplift significantly, with a further reduction available if there have been no prior assessments in the previous 24 months.
The ATO’s signalled a risk-based, facilitative approach during 2026–2027 for employers making genuine efforts to comply. Occasional late payments arising from rejected funds or incorrect details, where promptly fixed, are likely to be treated as low risk under this approach. Deliberate or serious non-compliance, however, will attract firmer action.
Payday super is a significant shift and your payroll processes should not be set and forget. Review your systems, data quality and governance arrangements before 1 July 2026 so you're ready to act fast when issues arise.
