Treasury Secretary Janet Yellen announced on Monday that just one week after a major new reporting requirement went into effect, over 100,000 small businesses have already registered with the department’s beneficial ownership database. “We’re closing a loophole and sending a clear message: The United States is not a haven for dirty money,” Yellen said during a visit to the Financial Crimes Enforcement Network, or FinCEN, headquarters in Vienna, Virginia. Initial numbers lagged behind earlier projections. FinCEN also estimates 5 million additional reporting companies annually over the next 10 years. A spokesperson for Treasury said that as more businesses learn if they are required to report under the new law, we expect filing numbers to grow exponentially. The new rules will make the registry available to law enforcement to expedite investigations into illicit activities, such as drug trafficking and tax evasion.
