Interest and administration fees¶

When super is late, the super guarantee charge is more than just the super you missed. It also includes an interest-like part and an administrative part. These are not there to punish — they exist to make things fair for the employee and to cover the cost of fixing the problem.

This lesson explains why each part exists, so the charge makes sense rather than feeling like a mystery.

In one line

Catching up the super is not enough on its own — the charge also covers the earnings the money would have made, the cost of putting it right, and interest on anything left unpaid.

Why this matters¶

If a late super payment only had to be caught up, an employee would still lose out — the money sat outside their fund and earned them nothing in that time. The extra parts of the charge exist to close that gap. Understanding them helps you see why acting quickly keeps the total smaller.

Understanding the concept¶

There are three extra parts worth knowing about.

Notional earnings. When super is late, the money was not in the employee's fund, so it did not earn anything there. The notional-earnings amount is an interest-like figure that stands in for those lost earnings. The point is not to catch up the super — it is to compensate the employee for the time the money was not working for them in their fund. This is why it is calculated from the day the super was due.

Administrative uplift. Sorting out late super takes work. The administrative uplift is an amount added to reflect the cost of putting the shortfall right. It exists because the system has to spend effort tracking and correcting the problem, and that cost sits with the employer who was late rather than everyone else.

General interest charge. If the super guarantee charge itself is not paid once it is assessed, a general interest charge (GIC) can build up on the unpaid amount. This is a separate, ongoing interest charge on money that is still owing. It exists because an unpaid debt to the ATO is money the community is going without, and it keeps building until the amount is paid.

For accountants & bookkeepers

The notional-earnings component is worked out from each employee's base shortfall and accrues from the day the contribution was due. The administrative uplift is a proportion of the shortfall and notional earnings, and it can be reduced where an early voluntary disclosure is made. The general interest charge compounds daily on the unpaid super guarantee charge (not on late-payment penalties) and, unlike the new charge itself, is not deductible. Keep the exact percentages and the GIC rate out of client advice — they move, and the ATO's assessment is the authoritative figure.

Example¶

Jordan's super for one payday reaches the fund late. The catch-up super is only part of the story. Because the money was outside the employee's fund for a while, a notional-earnings amount is added to make up for the earnings it missed there. An administrative amount is added to cover the cost of putting it right. Jordan pays the assessed charge promptly, so no further interest builds up. Had Jordan left the assessed charge unpaid, a general interest charge would have started to grow on top.

Common mistakes¶

Thinking paying the missed super is enough — the charge also covers lost fund earnings and an administrative amount.
Confusing the notional-earnings part with the general interest charge — the first compensates for lost fund earnings, the second builds up on an unpaid assessed charge.
Leaving an assessed charge unpaid — a general interest charge can keep growing until it is paid.

How this works in myaccountant¶

In the app — myaccountant works out the super for each pay and shows when it must reach the fund, so you can pay on time and avoid these extra amounts altogether. If a payment looks late or at risk, it is flagged so you can act early. myaccountant does not work out or charge interest, the administrative uplift or the general interest charge — those are set by the ATO and appear on its notice of assessment.

Key points¶

Late super means more than catching up — extra amounts also apply.
Notional earnings compensate the employee for earnings lost while the money was out of the fund.
The administrative uplift covers the cost of putting the shortfall right.
A general interest charge can build up on an assessed charge that stays unpaid.
Paying on time avoids all of these; paying an assessment promptly stops interest growing.
