Find Reporting Guidance
The directory links “Reporting tax evasion or fraud” for signs and reporting methods. Use that detailed page when deciding what information to provide; this directory is not a submission form.
Understand an Investigation
The investigation link explains why IRAS investigates, what happens during the process and what an involved person should do. A report and an investigation are different stages. The linked original provides the relevant process rather than this short directory deciding whether an allegation is established.
