Paying super late can now result in a charge significantly larger than the original unpaid contribution. Under the super guarantee charge framework introduced alongside Payday Super from 1 July 2026, an employer that misses the seven-business-day payment deadline can face the unpaid super amount, notional earnings and an administrative uplift of 60%.

The structure is designed to increase the financial consequences of delayed super payments while encouraging employers to correct errors as quickly as possible.

Four Parts to the New Charge

The new super guarantee charge is calculated for each relevant payday, referred to under the rules as a qualifying earnings day.

The first component is the individual final super guarantee shortfall. This represents the amount of super guarantee owed at 12% of qualifying earnings, less contributions received within the required timeframe and certain late contributions made before an assessment is issued.

The second component is notional earnings. These are calculated using the general interest charge rate and compounded daily on the relevant shortfall. The amount begins accruing after the seven-business-day payment window closes.

Notional earnings generally continue until a late contribution reduces the shortfall or an assessment is made, depending on the circumstances.

The third component is an administrative uplift equal to 60% of the total final shortfalls and associated notional earnings for the relevant payday.

The fourth component is a choice loading that may apply where an employer fails to comply with choice-of-fund requirements. The loading can equal 25% of the affected contributions and is subject to the applicable cap.

Because the calculation operates at employee and payday level, a payroll error affecting multiple workers across several pay cycles can create a substantially larger overall liability.

Why the 60% Uplift Matters

The 60% administrative uplift is one of the most significant features of the new framework.

Current rules allow the uplift to be reduced through regulation, potentially even to nil. However, unless such a reduction applies, employers must calculate the charge using the full uplift.

The design also makes the timing of corrective payments important.

If an employer identifies a missed payment and corrects it before an assessment, the remaining shortfall may be reduced. Notional earnings can also stop accumulating once the shortfall is addressed.

This can lower the amount on which the 60% uplift is calculated.

As a result, detecting payroll errors quickly can materially affect the final cost of a missed super payment.

A Hypothetical Example

Consider a hypothetical Adelaide retailer that pays a casual employee $2,500 on a payday.

At a 12% super guarantee rate, the required contribution is $300. A payroll processing error means the contribution does not reach the employee's super fund within the required seven-business-day period.

In the first scenario, assume the employer does not correct the issue before an assessment is made.

If $15 of notional earnings has accumulated by that point, the $300 shortfall plus $15 of notional earnings produces a total of $315.

A 60% administrative uplift on $315 would add $189.

The total charge would therefore be $504 before considering any additional choice loading, interest or penalties that may apply.

In the second scenario, assume the employer detects the problem earlier and pays the $300 contribution before an assessment.

If only $5 of notional earnings has accrued before the shortfall is cleared, the remaining amount subject to the uplift may be significantly smaller.

A 60% uplift on $5 would equal $3, producing a total charge of $8 based on these simplified assumptions.

The difference demonstrates how correcting a missed contribution quickly can substantially change the eventual liability.

The examples are illustrative only. Actual amounts depend on the timing of payments, applicable interest rates and the specific circumstances of the employer and employee.

What Happens After an Assessment?

Once the super guarantee charge has been calculated, an assessment can be issued to the employer.

The assessed amount becomes payable under the applicable rules. If the amount remains outstanding beyond the required payment period, further penalties and interest may apply.

Late payment penalties can generally equal 25% of the outstanding super guarantee charge.

In some circumstances, particularly where an employer has previously been liable for the same penalty within the relevant period, the rate may increase to 50%.

General interest charge can also accrue on unpaid super guarantee charge liabilities.

These additional costs sit on top of the original shortfall, notional earnings and administrative uplift, meaning unresolved liabilities can become progressively more expensive over time.

Tax Deductibility Under the New Regime

One significant change under the new system is the tax treatment of super guarantee charge payments.

Super guarantee charge paid under the new framework can generally be deductible.

This differs from the treatment under the previous quarterly system, where the charge was not deductible.

However, not every associated amount receives the same tax treatment.

General interest charge arising on unpaid super guarantee charge liabilities is not deductible, and late payment penalties are also generally non-deductible.

The distinction means employers may receive a tax deduction for the underlying super guarantee charge while still bearing the full after-tax cost of certain penalties and interest.

How the New Structure Differs From the Previous System

The previous super guarantee charge framework used a different calculation structure.

Under the older system, the charge generally incorporated the unpaid super amount, nominal interest and a fixed administration fee per employee per quarter.

The new system moves away from a flat administrative fee and instead uses a percentage-based uplift.

This means the administrative component now scales with the size of the underlying shortfall and associated notional earnings.

Larger payroll errors can therefore produce proportionately larger administrative charges.

The shift also reflects the move from quarterly super payment obligations to a system more closely tied to individual payroll cycles.

First-Year Compliance Considerations

The first year of the new regime runs from 1 July 2026 to 30 June 2027.

During this period, employers are expected to adapt payroll and superannuation processes to the new payment timetable and reporting requirements.

However, transitional compliance settings do not remove the underlying obligation to pay super on time or change how the statutory charge is calculated where a shortfall occurs.

Employers therefore need systems capable of identifying failed payments, rejected contributions, incorrect employee details and processing delays quickly.

Prompt correction remains important because delays can increase both notional earnings and the amount exposed to the administrative uplift.

Payroll Timing Becomes More Important

The seven-business-day payment window places greater emphasis on payroll timing.

Public holidays, weekends and year-end shutdown periods can reduce the number of available processing days and create additional operational pressure.

Employers may need to account for delays between initiating a super payment and the amount actually reaching an employee's super fund.

A contribution that is processed internally on time but received by the fund outside the required window may still create compliance issues depending on the applicable rules.

Payroll reconciliation, employee super details and payment clearing times therefore become more important under the Payday Super framework.

What Employers Should Watch

Employers should continue monitoring any changes to the regulations governing the 60% administrative uplift.

The legislation allows for the uplift to be reduced through regulation, so future amendments could affect how the charge is calculated.

Businesses should also monitor the timing of assessments and how super payment errors are treated in practice during the first year of the new regime.

Payroll systems may need regular review to ensure super contributions are calculated accurately and transferred within the required timeframe.

The financial consequences of late payment make early detection and correction increasingly important.
