http://www.irs.gov/businesses/small/article/0,,id=152532,00.htmlCongress passed the Bank Secrecy Act in 1970 as the first laws to fight money laundering in the United States. The BSA requires businesses to keep records and file reports that are determined to have a high degree of usefulness in criminal, tax, and regulatory matters. The documents filed by businesses under the BSA requirements are heavily used by law enforcement agencies, both domestic and international to identify, detect and deter money laundering whether it is in furtherance of a criminal enterprise, terrorism, tax evasion or other unlawful activity.
The Internal Revenue Service is a partner in the U.S. National Money Laundering Strategy. The IRS seeks to achieve a balance between enforcement of the money laundering laws and education. This page provides links to information about specific BSA requirements to assist with education and compliance with the law.
Suspicious Activity Reports-
http://www.irs.gov/businesses/small/article/0,,id=154555,00.htmlWhen to File a SAR
An MSB must file a SAR when it knows or suspects that:
The funds come from illegal activity or disguise funds from illegal activity;
The transaction is structured to evade BSA requirements or appears to serve no known business or apparent lawful purpose; or,
The MSB is being used to facilitate criminal activity.
***An SAR is different from a CTR (the $10,000 one) in that it doesn't have to be $10,000, it is reported after the bank becomes suspicious due to odd transactions, usually noted over a period of time.
This was in force before the Patriot Act.
Banks are forced to comply or face Federal Charges.
Failure to file a suspicious activity report may lead to civil and criminal penalties. A civil penalty may apply for each willful violation of the reporting requirements. The amount of the penalty is not to exceed the greater of the amount involved in the transaction (not to exceed $100,000), or $25,000. Any person who willfully violates the reporting requirements may be subject to criminal penalties, including a fine as great as $250,000 or five years imprisonment.
MSBs and their employees are prohibited from disclosing to a person involved in the transaction that a suspicious activity report has been filed. Further, each MSB or MSB employee is protected from civil liability for any SAR that they filed.
In other words, a bank cannot ask about the oddness of the transaction and/or tell the person that they are filing a report. This is a major difference between the SAR and the CTR. The other difference being the $10,000 stip on the CTR...which, funnily enough, created a need to use the SAR.
