In 2010-11 we successfully prosecuted 1,692 of the 1,941 cases taken to court, comprising:

  • 1,638 successful prosecutions from 1,890 cases related to non-lodgment and failure-to-comply tax offences
  • 54 successful prosecutions from 54 cases related to more serious offences. Of these
    • 45 resulted in custodial sentences, ranging from six months to over nine years
    • 7 resulted in penalties including fines and good behaviour bonds
    • 2 resulted in a guilty finding but convictions weren't recorded.

In addition to the above, there were eight successful prosecutions under Project Wickenby, resulting in custodial sentences ranging from fully suspended to 8.5 years.

Compliance effectiveness measures suggest that the indirect impacts of compliance activities were generally higher than the direct results.
