Correcting historical super¶

Sometimes you review your records and realise super for an earlier period was not paid, or was paid short. This can happen to careful employers — a worker was missed, the wrong amount was used, or a payment never reached the fund. The good news is that there is a clear way to fix it, and acting early usually leaves you better off.

This lesson walks through the calm steps: work out what was owed, tell the Australian Taxation Office (ATO) about it, and let the ATO work out the extra charge that applies.

In one line

If you find super was underpaid or missed in the past, work out what was owed, disclose it to the ATO early, and the ATO works out the super guarantee charge and sends you a notice of assessment.

Why this matters¶

Unpaid or short super does not go away on its own. Once you spot it, the sooner you act the better. The ATO explains that when super is not paid correctly, an extra charge applies on top of the amount owed — but it also says that fixing the shortfall and disclosing early can reduce what you pay. Sitting on it only makes it larger.

Understanding the concept¶

A super shortfall is super you should have paid for an earlier period but did not pay in full, or did not pay on time so the fund did not receive it in time.

When there is a shortfall, the ATO applies the super guarantee charge (SGC). The ATO describes this as more than just the super you owe — it is designed so that paying late or short is not cheaper than paying correctly on time.

The important change to know: the ATO says that when it finds a shortfall, the ATO works out the super guarantee charge and sends you a notice of assessment. You do not calculate and self-lodge that charge yourself. (Older periods followed a different, pre-1-July-2026 process where employers lodged a statement — so if your shortfall is from an older period, check the current ATO process for how it is handled.)

The other important point: the ATO says that paying the outstanding super to the employee's fund, and disclosing to the ATO before an assessment is issued, can reduce the charge. Early action is rewarded.

For accountants & bookkeepers

The ATO's guidance is that a voluntary disclosure made before it assesses the SGC can reduce the administrative uplift component, with a larger reduction the earlier the disclosure is made. From 1 July 2026 the base used to work out both super and the SGC is qualifying earnings. Historical periods may sit under the earlier rules and the earlier lodgment process, so confirm which process applies to the period in question before quoting figures — always check the current ATO guidance rather than relying on remembered rates.

Example¶

Jordan runs a small cafe and reviews the year's payroll records. Jordan notices that one casual worker was missed for a period some quarters ago — their super was never paid to their fund.

Jordan stays calm and works through it. First, Jordan works out what was owed for that worker over the affected period. Next, Jordan pays the outstanding super to the worker's fund and keeps a clear record of what happened and how it was fixed. Then Jordan discloses the shortfall to the ATO rather than waiting to be contacted.

Because Jordan disclosed early, the ATO works out the super guarantee charge and sends Jordan a notice of assessment showing what to pay. Jordan has already fixed the underlying super and kept good records, so the situation is under control.

Common mistakes¶

Waiting and hoping it resolves itself — a shortfall grows, it does not shrink.
Trying to self-calculate and lodge the charge — under the current rules the ATO works out the super guarantee charge and issues a notice of assessment.
Assuming an older period follows today's process — check the current ATO process for the period involved.
Not keeping a record of the shortfall and how it was fixed.

How this works in myaccountant¶

In the app — myaccountant keeps records of the super it works out and the super you pay, so you can spot a period where an amount was missed or fell short. It also flags payments that are at risk so problems are easier to catch early. The super guarantee charge itself is worked out and assessed by the ATO, not inside the app.

Key points¶

A super shortfall is super owed for an earlier period that was underpaid or not received by the fund in time.
Work out what was owed, pay it to the employee's fund, and keep a record.
Disclose the shortfall to the ATO early — doing so before an assessment can reduce the charge.
The ATO works out the super guarantee charge and sends you a notice of assessment.
Older periods followed a different, pre-1-July-2026 process — check the current ATO process.
Acting early keeps the amount smaller and the situation under control.
