Small business owners who have received an ATO letter warning that their employees’ super “may not” have been paid have had their complaints aired in Parliament. At Senate Estimates on Wednesday 28 October, senior tax officials were questioned over whether data-matched “nudge letters” were reaching employers who had done nothing wrong.
What the letters say
According to a letter viewed by Accountants Daily, the correspondence carries the heading “Your data shows you may not have met your quarterly super guarantee (SG) obligations”. It is based on information employers report through Single Touch Payroll and information their employees’ super funds report to the ATO, and tells recipients they may need to lodge an SG charge statement and pay.
The exchange at Estimates
Senator Malcolm Roberts argued that the ATO’s modernised system only holds records from 1 July 2018, with earlier contributions in a separate archive. “If the search [on the ATO system] returns blank, that does not mean that the superannuation was never paid; it means your later system does not hold that data. It seems that directors were wrongly charged,” he said.
Second Commissioner Jeremy Hirschhorn said he was sceptical of that claim but would look into it, asking for records of the specific complaints. “What you describe does not sound to me like what is happening,” he said.
He did, however, concede the limits of data matching. “Generally, when we do run data matching programs, we do our best not to fall in the trap of what I’ve described as data hubris. Data is just data, and it can have errors in it,” Mr Hirschhorn said. “Our general posture when we see what look to us like taxpayer errors in our data, our general stance is to show that data to the taxpayer and to give them a chance to understand what we think we know about that person and to either take action or explain the discrepancy.”
Asked how many taxpayers had been treated under a debt waiver mechanism for debts they never owed, Commissioner Rob Heferen said: “I hazard a guess it would be zero, but we’ll take that on notice.”
What the ATO says a letter is, and isn’t
“The ATO does not issue automated Superannuation Guarantee (SG) assessments or penalties,” an ATO spokesperson told Accountants Daily. “A nudge letter is not an assessment of SG, nor does it impose penalties. A nudge letter also does not automatically escalate to an audit.”
That is not the end of the matter. The ATO confirmed that the top penalty rate of 200% may apply to outstanding SG liabilities, and said assessments and penalties may follow if an audit later finds an employer has not met its obligations. Shadow Treasurer Tim Wilson told 3AW the ATO was “threatening small businesses with 200 per cent fines if they don’t basically bow to the ATO’s demands”.
A profession under pressure
The hearing came as Accountants Daily published its first ATO Sentiment Report on 3 November. It found 87% of accountants surveyed think the ATO has become somewhat or significantly more aggressive in its enforcement and compliance approach, seven in 10 have clients who have been contacted over debt recovery, and clients in construction and trades were by far the most likely to be contacted.
What employers can do
Because the letters refer to the quarterly system that applied before Payday Super began on 1 July 2026, the practical response is to reconcile the quarters listed against payroll and Single Touch Payroll reports, clearing-house confirmations and the dates funds actually received contributions. Where the records show a genuine shortfall, acting promptly matters; where they don’t, keep the evidence and respond, ideally through a registered tax or BAS agent.
