Congress 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.
