For FY2003/04, the income tax audit cases included a one-time recovery following the completion of the project on benefits derived by directors from interest-free/subsidised loans.
The definition of corporate income tax compliance cases was revised from FY2021/22 to better reflect IRAS’ overall work done and contributions in terms of compliance.
From FY2004/05, GST refund review cases were not included in the GST audit figure.
