What is SAR?

SAR means suspicious activity report, a confidential filing that certain U.S. financial institutions submit to FinCEN when they detect activity that may involve money laundering, fraud, sanctions evasion, or other reportable suspicious conduct. Outside the United States, similar reports are often called suspicious transaction reports, or STRs.

Definition

A SAR is not a customer notice or an accusation. It is a regulatory report supported by facts, patterns, transaction data, and a narrative that explains why the activity appears suspicious under the institution's obligations.
