Bloomberg pleaded guilty to willfully failing to file a "Report of Foreign Bank and Financial Accounts," for 2008 when he wired more than $540,000 from his Swiss UBS bank account to a United States bank account
The Justice Department alleged Bloomberg controlled the account from 1997 through 2008. It notes that U.S. residents must file the report by June 30 of the following year for any account with an aggregate value of more than $10,000 in a calendar year if it is held in a foreign country.
