all of jersey's 100000 inhabitants are profiting from the island's tax haven status but how did it come about in the 1st place. well jersey used to be a quiet island that lived from agriculture and tourism most people had nothing to do with finance. but jersey isn't just any old british island. it's a crown dependency meaning it's one of the direct sovereignty of the british crown and that is everywhere but that doesn't mean jersey is part of the u.k. . confusing right it means it has its own government and makes its own laws one of them is 0 tax policy on almost all companies and jersey has one company for every 3 people and over 330000000000 euros of funds under
