# FATF R.20 — Reporting of suspicious transactions
- **Part of:** [[FATF Recommendations]]
A financial institution that suspects, or has reasonable grounds to suspect, that funds are proceeds of criminal activity or related to terrorist financing must be legally required to report its suspicions promptly to the financial intelligence unit (FIU). The obligation is direct and mandatory, covers attempted as well as completed transactions, and applies regardless of the transaction amount; an indirect or implicit reporting duty triggered only by fear of prosecution is not acceptable.
