The American system of taxation is based on the premise that all income is taxable (which includes illegally earned income). In many instances, proving that a taxpayer willfully attempted to hide income from the Federal Government is an integral part of proving other criminal activity including fraud, money laundering or Bank Secrecy Act violations. Criminal Investigation continues to fulfill the important role of helping to ensure the integrity and fairness of our nations' tax system.
The Internal Revenue Service Criminal Investigation Division conducts criminal investigations regarding alleged violations of the Internal Revenue Code, the Bank Secrecy Act and various money laundering statutes. The findings of these investigations are referred to the Department of Justice for recommended prosecution.
