Reporting resources
The reporting guide explains signs of tax evasion and how to send information to IRAS. Use that official process for a suspected case, with factual details supporting the concern.
Investigation guidance
The linked investigation page explains why IRAS investigates and what happens if a taxpayer is involved. An investigation is different from a routine account enquiry or Annual Value objection.
