In 2021, Congress passed the Corporate Transparency Act (CTA). Shortly after, the Department of the Treasury’s Financial Crimes Enforcement Network (FinCen) began work on regulations designed to implement the CTA. The purported purpose is to combat illegal activity that is hidden behind business entities (for example, money laundering). The proposed regulations have now been published, and it is clear that they will require closely-held businesses to report ownership and other information to the Treasury.
