Under the Bank Secrecy Act, a financial institution must file a Suspicious Activity Report (SAR) within how many days of detecting a suspicious transaction?

Correct answer: 30 calendar days

Under the Bank Secrecy Act and FinCEN regulations, a SAR must be filed within 30 calendar days of the date the institution initially detects facts that may constitute a basis for filing. If no suspect is identified, the institution may delay filing up to 60 days to identify a suspect, but the standard deadline is 30 days. 15 days is too short and not the regulatory standard. 60 days is only allowed under the no-suspect exception. 90 days has no basis in SAR filing requirements.
