This document discusses tax havens and offshore financial centers (OFCs). It defines tax havens as jurisdictions that use laws and secrecy to help other entities avoid taxes in other jurisdictions. OFCs are defined as jurisdictions that provide disproportionate financial services to non-residents. Key characteristics of tax havens and OFCs are low or no taxes, strong protections on financial privacy, and lack of transparency. Examples of tax havens include Luxembourg, Switzerland, and Delaware. Examples of OFCs include the Bahamas, Bermuda, and Switzerland. OFCs specialize in services like shipping/aircraft registration, insurance, banking, and collective investment vehicles.
