Banking secret is an option present at a legal and sometimes constitutional level in some jurisdictions that apply a certain "veil" or "veil" of privacy on information relating to a current account. These privacy options change from jurisdiction to jurisdiction and are not all the same and do not still lend themselves to all types of open accounts. In fact, a private entity to open an account in a country that enjoys banking secret, will in fact be able to use it only if you also transfer with the tax residence. In fact, it is the tax residence, the legal parameter on which offshore banking bodies determine whether a person can take advantage of the banking secret or must instead be subject to the exchange of banking information with their own country of origin.
Only those who truly and legally move to another country will be able to benefit from the banking secret of that country. Otherwise the banks will be obliged to make an exchange of information with the European tax authorities on the same dynamic of the exchange that already takes place between institutions and tax authorities that are part of the European Community.
