What is suspicious activity report?

A suspicious activity report is a confidential filing that financial institutions submit to FinCEN when a transaction is suspected to involve fraud or other illicit activity, under the Bank Secrecy Act.

Also called SAR · BSA reporting

SAR data is the basis for much of the published statistical record on payment fraud in the United States, including FinCEN's financial trend analyses on business email compromise and mail theft related check fraud.

Filing is an institution obligation, not a customer one, and the existence of a SAR cannot be disclosed to the subject. For a defrauded business, the practical reporting path is the bank, the FBI IC3, and law enforcement.

Common questions

Can a business file a suspicious activity report?

No. Filing is an obligation of financial institutions. A defrauded business reports to its bank and to the FBI IC3.

Why does SAR data matter for fraud research?

It is one of the few sources describing incident mechanics at national scale, and FinCEN publishes trend analyses derived from it.
