Useful reporting information
Use the official reporting template to identify the person or business, describe how the conduct occurred, give amounts and years, explain how you learned of it, and provide evidence already in your possession. IRAS independently evaluates the information and does not handle unrelated private commercial or personal disputes. Reports can be anonymous.
Confidentiality and discretionary rewards
Tax secrecy prevents IRAS from updating informants on another taxpayer’s investigation or outcome. A requested reward can be 15% of tax recovered, capped at S$100,000, but is solely discretionary after recovery. Reward applicants identify themselves at the initial report and must not have participated in the evasion or supplied false information. The original explains legal exceptions to informer-identity protection.
