Suspicious Activity Report (SAR)

What is a Suspicious Activity Report (SAR)?

Suspicious Activity Report (SAR)

Suspicious Activity Report (SAR) is a report to the Financial Crimes Enforcement Network (FinCEN) to report any suspicious transaction that indicates money laundering, terrorist financing, fraud, or relates to a possible violation of law or regulation.

SARs are an important tool in the hands of federal and State law enforcement agencies in identifying, investigating, and prosecuting criminals by uncovering the financial connections to the crime. FinCEN, bank supervisory agencies, and various law enforcement agencies use SARs to investigate and analyze criminal activities. SAR information is used on a case-by-case basis and by identifying and analyzing existing and emerging trends and patterns in financial crime.

Who Needs to File a Suspicious Activity Report?

Various financial institutions are required to file SAR, which includes banks, loan or finance companies, broker or dealer in securities, money services business, casinos, and other institutions.

Are Mortgage Lenders or Originators Required to File SARs?

Yes. Mortgage lenders and mortgage originators are required to comply with the FinCEN's Bank Secrecy Act regulations and file a SAR when the transaction meets SAR reporting requirements. This requirement applies to mortgage lenders or originators that are part of a Bank, independent mortgage lenders, mortgage loan originators/brokers, and housing government sponsored enterprises. Independent mortgage lenders and mortgage brokers are considered a loan or finance company (31 CFR 1010.100(lll)). Housing government sponsored enterprises includes The Federal National Mortgage Association, The Federal Home Loan Mortgage Corporation, and each Federal Home Loan Bank (31 CFR 1010.100(mmm)).

As a result of SAR filing requirements, the mortgage lenders, mortgage originators, and housing government sponsored enterprises must have a program to monitor and detect suspicious transactions.

SAR Filing

When to File a SAR?

As per FFIEC Bank Secrecy Act Anti-Money Laundering Examination Manual, a SAR is required to be filed with respect to:

  1. Criminal violations involving insider abuse in any amount.
  2. Criminal violations aggregating $5,000 or more when a suspect can be identified.
  3. Criminal violations aggregating $25,000 or more regardless of a potential suspect.
  4. Transactions conducted or attempted by, at, or through the bank (or an affiliate) and aggregating $5,000 or more, if the bank or affiliate knows, suspects, or has reason to suspect that the transaction:
    1. May involve potential money laundering or other illegal activity (e.g., terrorism financing).
    2. Is designed to evade the BSA or its implementing regulations.
    3. Has no business or apparent lawful purpose or is not the type of transaction that the particular customer would normally be expected to engage in, and the bank knows of no reasonable explanation for the transaction after examining the available facts, including the background and possible purpose of the transaction.

These requirements are based on the regulations specified in FinCEN regulations - Chapter X (31 CFR 1000 to 31 CFR 1099).


Due Dates for Filing SAR

A reporting entity is any bank, mortgage lender, mortgage originator, or any other entity that is required to file a SAR. The timing for SAR filing starts after the date of the initial detection by the reporting entity of facts that may constitute a basis for filing a SAR. In other words, the timing for SAR filing is counted from the date the reporting entity detects suspicious activity. The due date for SAR filing is based on the following:

  1. If a suspect is identified, then a SAR must be filed no later than 30 calendar days after the date when the suspicious activity was detected.
  2. If a suspect is not identified, then a SAR must be filed no later than 60 calendar days after the date when the suspicious activity was detected.

How to file a SAR?

SARs are filed electronically with FinCEN using their BSA E-Filing System. From April 1, 2013, FinCEN only accepts electronic filing through BSA E-Filing System and no longer accepts paper forms or other legacy forms. Visit FinCEN's Filing Information webpage for details for BSA forms and filing requirements.

SAR Quality

FinCEN and other regulatory agencies expect a SAR to be complete, accurate, and timely. SARs must be supported by adequate documentation to show how details of the transaction. It is essential that a reporting agency files ensures that its staff is reviewing the SAR quality before it is filed.


Prohibition on Disclosure of SAR

Federal regulations prohibit disclosure of a SAR or any information that would reveal the existence of a SAR. This prohibition applies to any entity reporting the SAR, which includes bank, mortgage lender, loan or finance company. The prohibition also applies to the directors, officers, employees, or agents of the reporting entity. Therefore, it is essential that the confidentiality of the SAR is maintained at all times.


Record Retention

The FinCEN regulations requires the bank, lender, or reporting entity who filed the SAR or on whose behalf the SAR is filed to maintain a copy of SAR and the originals of all supporting documentation for a period of five years from the date of filing the SAR. The entity must be able to provide the documentation to a federal or state examining authority to demonstrate that the SAR filing requirements have been met.
