US DOJ said that Switzerland-based Basler Kantonalbank (BKB) has admitted to conspiring to defraud the U.S. on taxes, commit tax evasion and file false federal tax returns from 2002 to 2012.

The bank has agreed to pay $17.2 million to the IRS that represents unpaid taxes stemming from its role in the conspiracy, $29.7 million to the U.S. government that represents gross fees it earned on undeclared accounts, and a fine of $13.5 million
