On July 27, Congressman Lloyd Doggett 
(D-TX) introduced the Stop Tax Haven Abuse Act (H.R. 2669) in the House of Representatives with 53 cosponsors. The Senate version was introduced July 12 by Sen. Carl Levin.
The U.S. Treasury loses an estimated $100 Billion in tax revenues annually due to tax havens. Many believe the actual revenue loss could be much higher.
A key provision would tax corporations where they are located and do business instead of where they are incorporated, say, a post office box in the Cayman Islands. Another important provision would require companies that file with the SEC to report certain financial information on a country-by-country basis so that investors and tax authorities could see where operations are located and where profits are ending up.
Most of the Stop Act provisions are aimed at the foreign financial institutions and foreign jurisdictions that facilitate offshore tax evasion and avoidance. The bill also targets some other types of tax dodging, as well as the bankers, lawyers, and accountants who facilitate these abuses by their clients.
A new report by CTJ explains the bill’s provisions.
