Each year, the United States loses an estimated $100 billion in tax revenues due to offshore tax abuses. The U.S. Senate Permanent Subcommittee on Investigations has examined various aspects of this problem, including how U.S. taxpayers have used offshore tax havens to escape payment of U.S. taxes. This Report focuses on a different subset of abusive practices that benefit only non-U.S. persons, have been developed and facilitated by leading U.S. financial institutions, and have been utilized by offshore hedge funds and others to dodge payment of billions of dollars in U.S. taxes owed on U.S. stock dividends.
