They delve into the legislative process, the potential for the bill to pass by July 4th, and the consequences if it fails. A significant portion of the discussion is dedicated to Section 899, which addresses concerns about the Pillar Two UTPR and digital services taxes, including its potential impact on US BEAT regime and international tax treaties.
