Jersey is one of the top worldwide offshore financial centers.^[13] It is described by some as a tax haven.^[14] It attracts deposits from customers outside of the island, seeking the advantages such places offer, like reduced tax burdens.

Jersey has been variously given the title of a 'tax haven' since the 1920s, when wealthy Brits began to move (or move their wealth) into the island to avoid wealth and inheritance taxes. Its taxation laws have been widely criticised by various people and groups.
