• modifies the base erosion anti-abuse tax to lower the gross receipts applicability threshold from $500 million to $100 million,
• makes investment advisers and persons engaged in forming new business entities subject to new anti-money laundering requirements,
• requires reporting of U. S. beneficial owners of foreign-owned financial accounts, and
• imposes additional requirements for third party summonses used to obtain information in tax investigations that do not identify the person with respect to whose liability the summons is issued (i.e., John Doe summons).
