Guide to SARs: Suspicious Activity Reports

A suspicious activity report, or SAR, is a document that financial institutions must submit to the federal government when they detect unusual and suspicious activities. SARs serve as an early warning system for the authorities, helping law enforcement detect, investigate, and prevent financial crimes like money laundering, fraud, and terrorist financing.

Here’s a closer look at what a SAR is and what type of financial activity triggers a suspicious activity report.

Key Points

•  Financial institutions file suspicious activity reports (SARs) to alert authorities about unusual or illegal activities.

•  The Financial Crimes Enforcement Network (FinCEN) regulates SARs under the Bank Secrecy Act.

•  Large cash transactions, unusual account activity, and structuring transactions to evade reporting are common triggers for SARs.

•  SARs are held in a database that law enforcement agencies can search, helping them uncover networks and prevent financial crimes.

•  Banks are not allowed to disclose SARs to customers, but many reports never lead to charges or adverse consequences.

What Is a SAR?

A SAR, or suspicious activity report, is the standard document that banks and some other businesses must file with the Financial Crimes Enforcement Network (FinCEN) if they detect unusual behavior by an individual or organization. These reports are housed in a central government database and are designed to pick up illegal activities, such as money laundering, tax evasion, criminal financing, or other types of fraud that would not be flagged under other reports.

SAR filings can be triggered by any type of financial transaction that is out of the ordinary, such as large cash deposits or withdrawals into bank accounts, frequent wire transfers to countries known for criminal activity, structuring transactions to avoid reporting requirements, and any transaction that doesn’t seem to have a legitimate business purpose.

A suspicious activity report will contain details about the suspect transaction, the parties involved, and the reasons why the transaction is considered suspicious. The financial institution is not required to provide proof that a crime has occurred, nor is the institution’s client notified that a SAR related to their account has been filed.

The data contained in SARs is made available to multiple law enforcement agencies and is often combined with other information to build cases and prevent financial crimes.

Who Regulates SARs?

In the United States, the Financial Crimes Enforcement Network (FinCEN), a bureau of the U.S. Department of the Treasury, regulates SARs.

Under the Bank Secrecy Act (BSA) of 1970, banks and other financial institutions must file SARs with FinCEN to help government agencies detect and prevent money laundering and other financial crimes. Traditionally, this meant filing a paper report, but starting in 2013, FinCEN moved its reports entirely online. Businesses and individuals now use the BSA E-Filing System to submit a SAR.

FinCEN sets the rules and guidelines that determine when a SAR should be filed, what information should be included, and how financial institutions should handle suspicious transactions.

Who Can Make SARs?

Generally, financial institutions and businesses engaged in financial services are required to make SARs. This includes banks, credit unions, stock/mutual fund brokers, and different kinds of money service businesses (such as check-cashing companies and money order providers). Other types of businesses that must submit SARs include:

•  Casinos

•  Precious metals and gems dealers

•  Insurance companies

•  Mortgage companies

Essentially, if there is an opportunity to launder money or commit any other type of financial crime, a business or organization (and its employees) are required to be aware of the rules and requirements of SARs.

Who Do SARs Alert?

A suspicious activity report often begins when an employee of a financial institution notices an unusual activity, such as large sums of money being deposited into an account that had never been used for that kind of activity, or an anonymous wire transfer of funds out of the country. The individual would then communicate their observation to a supervisor, who files a SAR.

When a SAR is filed, it goes to the Financial Crimes Enforcement Network, or FinCEN. This regulatory body is in charge of analyzing SARs and providing the resulting intelligence to law enforcement agencies, including the Federal Bureau of Investigation (FBI) and Drug Enforcement Administration (DEA). The information from SARs helps these agencies detect patterns of illegal activity and investigate cases that could otherwise go unnoticed.

What Triggers SARs?

A variety of situations can trigger the filing of a SAR. These scenarios typically involve activities that seem unusual, inconsistent with normal financial behavior, or indicative of illegal conduct. Here are some common triggers:

Large Cash Transactions

Unusually large cash deposits or withdrawals, especially when they are inconsistent with a customer’s usual banking patterns, can trigger a SAR. Financial institutions are required to report cash transactions exceeding $10,000 per day.

Unusual Account Activity

If there is sudden or unusual account activity, such as rapid transfers between accounts or sudden high-value transactions without an apparent legitimate purpose, a SAR may be filed. This type of activity could suggest money laundering, tax evasion, or fraud.

Structuring Transactions

Structuring occurs when an individual deliberately breaks up large amounts of money into smaller transactions to evade reporting requirements. This is a common tactic used in money laundering and can trigger the filing of a SAR.

Suspicious Wire Transfers

An unusually large number of wire transfers; wire transfers that fall into certain repeated patterns; and wire transfers to or from countries known for financial crime (such as tax evasion or terrorism) can trigger a SAR.

Unexplained Wealth

If a customer suddenly deposits large sums of money into a checking or savings account, or purchases expensive assets without a clear, legitimate source of funds, a SAR may be triggered. This could be seen as a sign of illicit activity, such as drug trafficking, corruption, or fraud.

Transactions Involving Shell Companies

The use of shell companies to conduct financial transactions can be considered suspicious. Shell companies often lack significant assets or operations and may be used to conceal the true nature of financial dealings, prompting a SAR filing.

What Happens When a SAR Is Triggered?

If your financial institution files a SAR due to any of your banking transactions, nothing would happen right away. And since banks are not allowed to disclose a SAR to customers, you would not even be aware of it.

Typically, If there’s no illegal activity involved, FinCEN will not pursue the issue and it will not have any negative impacts on your life. Banks routinely file SARs to avoid being cited for violating their legal responsibilities and many do not lead to adverse consequences. However, if a SAR is suspicious enough, it may gain the attention of federal law enforcement authorities.

If, after conducting an investigation, the government believes illegal activity occurred, it could potentially seek a court order to temporarily freeze your bank account. This is done to keep the funds in question from being withdrawn until the investigation is completed.

Why Suspicious Activity Reports Are Important

SARs play a vital role in combating financial crime. They provide a way for financial institutions to alert regulators to potential illegal activities, giving them an opportunity to investigate and take action before criminal activities escalate. SARs help prevent money laundering, terrorist financing, drug trafficking, tax evasion, and other serious crimes.

SARs also contribute to global efforts to combat financial crime, since the intelligence is often shared across borders. International cooperation is often crucial for investigating and prosecuting transnational criminal organizations, making SARs a valuable tool in global anti-money laundering efforts.

Are SARs Confidential?

Yes, SARs are confidential, and strict rules govern how they are handled. The person or organization that files a SAR is prohibited from disclosing the report’s existence or the fact that it has been filed. This confidentiality is crucial to ensure that the subject of the SAR is unaware of the investigation, thereby preventing them from altering their behavior, destroying evidence to cover their tracks, or fleeing.

Violating SAR confidentiality is a serious offense and can lead to legal penalties for the individual or institution responsible. The only parties allowed to know about the SAR are the regulatory authorities and law enforcement agencies involved in investigating the suspicious activity.

The Takeaway

Suspicious activity reports (SARs) are essential tools for detecting and preventing financial crime. These reports enable financial institutions to alert authorities when they encounter transactions that raise red flags for illegal activities such as money laundering, fraud, or terrorist financing.

However, SARs are commonly filed and, in many cases, do not lead to further investigation. As long as you’re not engaging in any illegal financial activities, a SAR should not have any impact on your life or cause any interruptions in your ability to use your checking or savings account.

FAQ

What triggers a suspicious activity report?

A suspicious activity report (SAR) is triggered when a financial institution detects unusual or potentially illegal activity. This can include large cash transactions, sudden changes in account usage, wire transfers to countries known for criminal activity, and structuring transactions (i.e., breaking up large amounts into smaller transactions to evade reporting requirements). The goal is to help government authorities detect and investigate crimes like money laundering, tax evasion, fraud, and terrorist financing.

What happens when you get a SAR?

If a bank or company submits a SAR about you, it is submitted to the Financial Crimes Enforcement Network (FinCEN). The report remains confidential, and you will not be informed. FinCEN reviews the SAR and may share it with law enforcement agencies for further investigation. Not all SARs lead to further investigation, however. A large number are simply routine and don’t lead to any adverse consequences.

What are examples of suspicious activity for SARs?

Examples of suspicious activity that can trigger a SAR include:

•  Large or unusual cash deposits or withdrawals

•  Transactions that seem unusual for the stated business type

•  Transactions inconsistent with a customer’s profile

•  Frequent international wire transfers to high-risk jurisdictions

•  Structuring transactions to avoid reporting thresholds

•  Use of shell companies for significant financial transactions

•  Sudden large asset purchases without a clear source of funds

SoFi members with direct deposit activity can earn 4.00% annual percentage yield (APY) on savings balances (including Vaults) and 0.50% APY on checking balances. Direct Deposit means a recurring deposit of regular income to an account holder’s SoFi Checking or Savings account, including payroll, pension, or government benefit payments (e.g., Social Security), made by the account holder’s employer, payroll or benefits provider or government agency (“Direct Deposit”) via the Automated Clearing House (“ACH”) Network during a 30-day Evaluation Period (as defined below). Deposits that are not from an employer or government agency, including but not limited to check deposits, peer-to-peer transfers (e.g., transfers from PayPal, Venmo, etc.), merchant transactions (e.g., transactions from PayPal, Stripe, Square, etc.), and bank ACH funds transfers and wire transfers from external accounts, or are non-recurring in nature (e.g., IRS tax refunds), do not constitute Direct Deposit activity. There is no minimum Direct Deposit amount required to qualify for the stated interest rate. SoFi members with direct deposit are eligible for other SoFi Plus benefits.

As an alternative to direct deposit, SoFi members with Qualifying Deposits can earn 4.00% APY on savings balances (including Vaults) and 0.50% APY on checking balances. Qualifying Deposits means one or more deposits that, in the aggregate, are equal to or greater than $5,000 to an account holder’s SoFi Checking and Savings account (“Qualifying Deposits”) during a 30-day Evaluation Period (as defined below). Qualifying Deposits only include those deposits from the following eligible sources: (i) ACH transfers, (ii) inbound wire transfers, (iii) peer-to-peer transfers (i.e., external transfers from PayPal, Venmo, etc. and internal peer-to-peer transfers from a SoFi account belonging to another account holder), (iv) check deposits, (v) instant funding to your SoFi Bank Debit Card, (vi) push payments to your SoFi Bank Debit Card, and (vii) cash deposits. Qualifying Deposits do not include: (i) transfers between an account holder’s Checking account, Savings account, and/or Vaults; (ii) interest payments; (iii) bonuses issued by SoFi Bank or its affiliates; or (iv) credits, reversals, and refunds from SoFi Bank, N.A. (“SoFi Bank”) or from a merchant. SoFi members with Qualifying Deposits are not eligible for other SoFi Plus benefits.

SoFi Bank shall, in its sole discretion, assess each account holder’s Direct Deposit activity and Qualifying Deposits throughout each 30-Day Evaluation Period to determine the applicability of rates and may request additional documentation for verification of eligibility. The 30-Day Evaluation Period refers to the “Start Date” and “End Date” set forth on the APY Details page of your account, which comprises a period of 30 calendar days (the “30-Day Evaluation Period”). You can access the APY Details page at any time by logging into your SoFi account on the SoFi mobile app or SoFi website and selecting either (i) Banking > Savings > Current APY or (ii) Banking > Checking > Current APY. Upon receiving a Direct Deposit or $5,000 in Qualifying Deposits to your account, you will begin earning 4.00% APY on savings balances (including Vaults) and 0.50% on checking balances on or before the following calendar day. You will continue to earn these APYs for (i) the remainder of the current 30-Day Evaluation Period and through the end of the subsequent 30-Day Evaluation Period and (ii) any following 30-day Evaluation Periods during which SoFi Bank determines you to have Direct Deposit activity or $5,000 in Qualifying Deposits without interruption.

SoFi Bank reserves the right to grant a grace period to account holders following a change in Direct Deposit activity or Qualifying Deposits activity before adjusting rates. If SoFi Bank grants you a grace period, the dates for such grace period will be reflected on the APY Details page of your account. If SoFi Bank determines that you did not have Direct Deposit activity or $5,000 in Qualifying Deposits during the current 30-day Evaluation Period and, if applicable, the grace period, then you will begin earning the rates earned by account holders without either Direct Deposit or Qualifying Deposits until you have Direct Deposit activity or $5,000 in Qualifying Deposits in a subsequent 30-Day Evaluation Period. For the avoidance of doubt, an account holder with both Direct Deposit activity and Qualifying Deposits will earn the rates earned by account holders with Direct Deposit.

Members without either Direct Deposit activity or Qualifying Deposits, as determined by SoFi Bank, during a 30-Day Evaluation Period and, if applicable, the grace period, will earn 1.20% APY on savings balances (including Vaults) and 0.50% APY on checking balances.
