Summary

This is an E-supplement to GAO-08-778. The Cayman Islands is a major center for financial activity and entities such as corporations, partnerships, and trusts can all play roles in those activities. U.S. taxpayers have a range of relationships to those entities, including as owners, as investors, as partners, and as beneficiaries of trusts. The activities of Cayman Islands entities can have tax consequences for under U.S. law. To understand more about the nature of financial activity in the Cayman Islands and its consequences under U.S. tax law, we examined relevant portions of Cayman Islands and U.S. law. This supplement discusses four areas of Cayman Islands and U.S. law. Part I is an overview of Cayman Islands law governing corporations, partnerships, and trusts. It also discusses the function of the registered office under Cayman Islands law. Part II presents an overview of Cayman Islands law governing the sharing of information by the Cayman Islands government with the U.S. government. Part III discusses certain Cayman Islands monetary authority and anti-money-laundering laws and compares specific Cayman Islands and United States regulations designed to combat money laundering. Finally, Part IV describes some of the obligations that can arise under U.S. tax law for Cayman Islands entities and for U.S. owners of Cayman Islands entities.
