Key Summary
Strong SAR narratives answer who, what, when, where, why, and how in plain language that law enforcement can act on. Most AML teams lose hours per filing to manual evidence gathering and drafting. RiskScout customers report a 40% reduction in SAR and CTR filing times with automation supporting the process.

This guide is designed to help you compose SAR narratives that are both informative and actionable for law enforcement. Leverage these tips and tricks to ensure your SARs are truly making a difference in protecting your community.

What Goes Into an Effective SAR Narrative
Per the FFIEC BSA/AML Examination Manual, the narrative is the only place in a SAR where the institution can tell the story in its own words. Effective narratives open with a one-paragraph description of the activity, identify every subject with complete information, lay out the facts in chronological order, and close with a summary and the institution's next steps. FinCEN's filing resources cover the mechanics; the downloadable guide below covers the craft, with the full templates and examples.
Frequently Asked Questions
What makes a strong SAR narrative?
A strong SAR narrative opens with a one-paragraph summary of the activity and the amounts involved, identifies every subject with complete identifying information, lays out the facts in chronological order, and closes with what the institution did in response. Law enforcement should be able to act on it without calling the institution to fill in basics.
When is an institution required to file a SAR?
Institutions must file a SAR for insider abuse involving any amount, suspected crimes of $5,000 or more when a suspect can be identified, suspected crimes of $25,000 or more regardless of suspect, and transactions of $5,000 or more that may involve money laundering or BSA evasion. These thresholds, including the insider abuse standard, come from the FFIEC BSA/AML Examination Manual.
How do teams cut down on SAR filing and narrative time?
Teams cut SAR filing time by keeping all case evidence in one record, standardizing narrative structure, and automating data population and deadline tracking. RiskScout customers report a 40% reduction in SAR and CTR filing times, with the Filing Scout handling preparation and deadlines.
When must a SAR be filed?
Within 30 calendar days of the initial detection of facts that constitute a basis for filing. If no subject can be identified, the deadline extends to 60 calendar days. The clock starts at detection, not at the end of the investigation.
How long should a SAR narrative be?
As long as it needs to be to tell the complete story. There is no fixed length requirement. Narratives that front-load the key facts in the opening paragraph are the ones law enforcement can act on fastest.
