Liechtenstein. According to CountryAAH, major public holidays in Liechtenstein include Independence Day (August 15) and New Year (January 1). Liechtenstein does not intend to jeopardize its banking secrecy even though the country remains on the OECD’s “black list” of tax havens and is threatened by sanctions. It proclaimed Crown Prince Alois in April, pointing out that the nation’s population would, by a referendum, reject all proposals for changed banking secrecy. Liechtenstein was singled out in 2002 by the OECD as one of 35 non-cooperative countries and territories in the exchange of bank account information. In 2006, five countries remained on the list.
