US Closes Key Money-laundering, Tax Evasion Path Agence France-Presse WASHINGTON - A major avenue for global money laundering and tax evasion has been closed off by a new law requiring disclosure of owners of U.S. shell companies used to hide billions of dollars. The Corporate Transparency Act was included in the U.S. defense appropriations bill that Congress passed into law late Friday, overriding President Donald Trump's veto. The law forces "beneficial owners" behind shell companies to report their identities to the U.S. Treasury's Financial Crimes Enforcement Network, or FinCEN. While the law still grants them protection from public knowledge -- only the Treasury and law enforcement will be able to access the FinCEN database -- transparency advocates say it is a huge step against kleptocrats, organized crime and rich tax evaders who have been able to anonymously wash their suspect wealth through the world's largest economy. "For years, experts routinely ranked anonymous shell companies ... as the biggest weakness in our anti-money-laundering safeguards," said Ian Gary, executive director of the FACT Coalition, which lobbied for the legislation. "It's the single most important step we could take to better protect our financial system from abuse," he added. The United Nations estimates that $800 billion to $2 trillion is laundered through the global financial system every year. While much of the attention has focused on tax havens like Panama and the Cayman Islands, experts say that the size of the U.S. economy, and its ability to absorb billions of dollars without notice, has made it crucial for converting illicit funds into legitimate assets. .
