Banks can be prosecuted by U.S. authorities for failure to report offshore accounts, for failure to report suspicious transactions, for processing suspicious transactions, and a host of other criminal acts. Many of the criminal acts that banks are prosecuted for involve the financial institution facilitating wrongdoing on the part of customers with which it is conducting business. 

Federal authorities take tax evasion seriously and are increasingly pursuing criminal charges against those who hid offshore accounts. Just recently, the CEO of Atlanta-based Circlenet, LLC was sentenced to four months incarceration in a federal prison for having undeclared income and offshore accounts that he had not declared. 

Federal authorities are going after not only banks, but also individual bankers and financial advisors who may have helped U.S. clients to evade their income tax obligations.  Just this past February, a superseding indictment was handed down against financial advisors who worked for Wegelin, one of Switzerland’s oldest banks. 

HSBC has been in trouble with the U.S. government in the past for the unlawful behavior of its private bank. In 2012, HSBC was fined for its role in facilitating money laundering.  Yahoo is now reporting on leaked documents from HSBC showing how involved the bank was not just in money laundering but also in helping people worldwide evade their income tax obligations.

Investors who used offshore accounts to hide money from the IRS are facing increased risks as the federal government launches new investigations into UBS and other offshore banks.  When banks and bankers make deals with the Department of Justice and with the Internal Revenue Service, these deals often involve turning over client information to the federal authorities.
