What happened
Australian employers must pay a superannuation guarantee (SG) into employees' retirement funds. The Australian Taxation Office (ATO) selects employers for SG compliance cases. Its two earlier risk models drew on historical fund and income tax data. In 2018–19 it replaced them with two real-time data models. The Employer Simulation and Evaluation Model compares employers' behavior across similar groups of employees. The SG Under Reporting model identifies under-reporting from Single Touch Payroll and Member Account Transaction Service data. The Australian National Audit Office (ANAO) published an audit of SG compliance on 28 April 2022. It states that the new models increased the average strike rate from approximately 60–70 percent to 90 percent. The strike rate is the share of SG compliance cases that raise a liability. The ANAO adds that the models need heavy data validation, use limited samples and depend on Excel work by a few experienced staff. The ATO told the ANAO in September 2021 that it used real-time data to select only around 200 cases in 2021–22. The report gives no source or method for the strike rates.

The new models increased the average strike rate from approximately 60–70 per cent to 90 per cent. However, the new models require a high level of data validation, involve limited sampled data sets and compliance cases, are manually intensive, and require intensive use of Microsoft Excel by a few experienced staff.

AI system
- Workflow
-
Employers reported pay through Single Touch Payroll and super funds reported contributions through the Member Account Transaction Service. The Employer Simulation and Evaluation Model compared each employer with similar groups of employees, and the SG Under Reporting model used payroll and fund data to identify under-reporting. Running the models took heavy data validation, manual work and intensive use of Microsoft Excel by a few experienced staff.
Follow-up
- Conditions for replication
-
Payroll and fund data must be matched reliably, and the ATO estimated that data integrity issues affected 10 to 15 percent of the data. Enough experienced staff must be available, since the models are manually intensive and use limited samples.

The Australian Taxation Office built the real-time data models to select employers who are likely to have underpaid the superannuation guarantee for compliance cases.
