Sovereign Management & Legal LTD is a company that the United States government believes helped U.S. citizens evade their income tax obligations. The U.S. government does not yet know who used the services of Sovereign to move money and assets offshore to hide them from the Internal Revenue Service and avoid paying income taxes that were due. 

The second largest bank in Israel, Bank Leumi, faces millions of dollars in potential penalties as part of a probe into whether the bank helped U.S. investors hide money and avoid paying the full amount of income taxes due to the United States government.
