More than 360 people were convicted for tax and super offences between 1 April and 30 June this year, the Australian Taxation Office (ATO) has reported.
Tax commissioner Michael D'Ascenzo said Australia generally had a strong culture of compliance, but a handful of people were still evading their tax and super obligations.
He said all forms of tax evasion and intentional non-compliance, whether it was failing to lodge a tax return, defrauding the Commonwealth, or committing identity or refund fraud, were taken very seriously.
Earlier this year, the ATO announced that it had upgraded its technology and had new risk filters in place to help detect over-claimed or fraudulent income tax refunds.
"We extensively cross-reference information reported in tax returns with information provided by third parties to identify errors or discrepancies. Last year, we matched over 500 million transactions," D'Ascenzo said.
"We will continue to strengthen our methods to detect returns that may be fraudulent and expand the use of our fraud detection models."
D'Ascenzo said two of the convictions this quarter also followed investigations by the ATO's Project Wickenby Taskforce into abusive secrecy haven arrangements.
"People need to manage their own tax affairs responsibly, because ultimately they will have to pay the consequences for their actions," he said.
For the 1 January to 31 March quarter, the ATO reported 489 convictions for tax and super offences.
An ATO spokesperson said the reason the figure was lower this time around was because the figure represented the number of people that had been convicted, rather than the number of convictions people had against them.
