When does the time period for filing a SAR commence?

The correct answer indicates that the time period for filing a Suspicious Activity Report (SAR) begins when the credit union suspects suspicious activity. This concept is rooted in the requirements of the Bank Secrecy Act (BSA) and the rules surrounding SAR filings.

The regulations stipulate that a financial institution must file a SAR within 30 days of detecting suspicious activity. This means that the clock starts ticking at the moment the institution has sufficient knowledge or a basis to suspect that a transaction or a series of transactions is suspicious, rather than waiting for a transaction to be completed or for any reporting cycle to be finalized.

This understanding emphasizes the proactive nature of BSA compliance, where institutions are encouraged to monitor transactions effectively and take immediate action upon identifying activities that may indicate money laundering, fraud, or other financial crimes. Filings made under these circumstances provide vital intelligence to FinCEN (Financial Crimes Enforcement Network) and other law enforcement agencies, enabling them to address potential criminal activities swiftly.
