Paying employees' superannuation late can look like anadministrative problem.
For one of our business clients, historical late payments hadcontributed to more than $50,000 of superannuationcosts becoming non-deductible, together with exposure to theSuperannuation Guarantee Charge (SGC), interest and other complianceconsequences.
When we reviewed the client's affairs, we identified that employeesuperannuation had repeatedly not been dealt with within the requiredhistorical payment timeframes.
By the time we identified the pattern, the tax consequences werealready significant.
Paying the super later didn't necessarily fix the tax problem
Under the rules applying to the historical periods involved,failing to make the required superannuation contributions by the applicablequarterly due dates could result in an SGC liability.
That mattered because SGC itself is not tax deductible.
Late contributions also required specific treatment. Depending onthe circumstances, an eligible late contribution could potentially be used as alate-payment offset against the SGC or carried forward towards a futurequarter. Those alternatives could have different deduction consequences.
For this client, after reviewing the historical payments and theirtreatment, more than $50,000 of superannuation costs hadultimately become non-deductible.
The cash had still left the business.
The employees' super obligations still had to be dealt with.
But the business had lost deductions it could otherwise haveobtained if the obligations had been managed correctly and on time.
The flow-on effect could extend beyond the deduction
A lost deduction can also affect the broader tax position.
If an expense is non-deductible, the taxable income of the companyor trust may be higher than it otherwise would have been.
Depending on the structure, that higher taxable income can thenhave flow-on consequences when profits are ultimately dealt with — for examplethrough company dividends or trust distributions.
The precise outcome depends on the entity, available frankingcredits, beneficiaries or shareholders and their individual tax positions.
The important point is that the cost of getting super wrong isn'tnecessarily limited to the super payment itself.
The rules have now changed — but payment timing matters even more
This case arose under the historical quarterly superannuationsystem.
From 1 July 2026, Payday Super changed thetiming of employers' super guarantee obligations.
Employers now calculate super guarantee on qualifying earningsassociated with each payday, and contributions generally need to be received bythe employee's super fund within 7 business days after payday,unless an extended timeframe applies.
That makes payroll systems, payment processing and monitoring evenmore important.
For this client, we couldn't go back and change the historicalpayment dates.
What we could change was the process.
Rather than discovering late super when preparing accounts or taxreturns months later, the objective was to build the obligation into theclient's ongoing payroll and compliance systems so problems could be identifiedbefore they became expensive.
More than $50,000 of lost deductions was a costly reminder:
Superannuation isn't paid on time simply because the payment waseventually made. The timing and treatment matter.
This case study has been generalised and certaindetails, including financial amounts, have been changed to protect client andbusiness confidentiality. It includes historical superannuation guaranteeobligations applying before the introduction of Payday Super on 1 July 2026.General information only. The consequences of late superannuation paymentsdepend on the period involved, the nature and timing of the contribution,applicable SGC rules and how late contributions are treated. From 1 July 2026,different Payday Super rules apply and employers should consider therequirements applicable to each payday.
