You form a shell company — meaning a business that exists only on paper, with no employees, no products it makes or sells, no revenue, nothing except maybe a bank account and some assets — but you do it without disclosing your (the owner’s) real name, offering a convenient way to launder your money and evade law enforcement in the United States. Except that might now be a lot harder to do in the US. A provision in the National Defense Authorization Act (NDAA), the $741 billion defense bill, will effectively ban anonymous shell companies.
