Suspicious Activity Reports

Edition label: 2026-10

Definition: A Suspicious Activity Report (SAR) is the regulatory filing that U.S. financial institutions are required by the Bank Secrecy Act (31 U.S.C. § 5318(g)) and Financial Crimes Enforcement Network (FinCEN) regulations to submit when they identify activity meeting the criteria for possible criminal conduct (including money laundering, structuring, and other suspected illicit financial activity).1 SARs are filed confidentially with FinCEN and are not disclosable to the subject of the report.2

Overview

SARs are the principal documentary artifact through which financial institutions discharge — or fail to discharge — their BSA detection-and-reporting obligation.3 The filing standard concerns a financial institution’s knowledge or suspicion that a transaction meets specified regulatory criteria; the deadline is 30 calendar days after initial detection (extendable to 60 days when the subject is unknown).4

In the Epstein-network record, SAR filings (and their absence) are a central documentary basis for establishing the gap between what the BSA framework would have required and what banks actually filed, alongside internal emails and due-diligence reports that document bank-institutional knowledge.

The cited Senate materials describe a post-arrest retroactive-filing pattern at JPMorgan: seven SARs covering about $4.3 million filed between 2002 and 2016, followed by two SARs filed on August 13 and September 26, 2019 (after Epstein’s July 6, 2019 arrest and his August 10, 2019 death) covering about $1.3 billion in transactions dating back to 2003.5 A House letter describes the earlier period differently, saying JPMorgan filed no SAR at all before Epstein’s death.6 The most quantitatively explicit case is JPMorgan:

SAR confidentiality vs. congressional access

SARs are statutorily confidential, with limited disclosure permitted to law enforcement and regulatory authorities.1213 The cited Wyden Department of Justice (DOJ)/Treasury letter describes a dispute over congressional access to FinCEN records.14
