The Financial Crimes Enforcement Network (FinCEN) is a U.S. Treasury bureau that combats financial crime and safeguards whistleblowers. Their Anti-Money Laundering and Sanctions Whistleblower Program encourages reporting violations of the Bank Secrecy Act and related sanctions. They offer confidentiality, potential financial rewards (up to 30% of recovered funds), and protection from retaliation. Individuals can report anonymously through secure channels like a hotline or online portal. FinCEN utilizes this information to support investigations and pursue legal action against offenders, ultimately strengthening financial security and combating illegal activities.
