Banishment

To be in exile means to be away from one's home (i.e. city, state, or country), while either being explicitly refused permission to return or being threatened with imprisonment or death upon return. It can be a form of punishment and solitude. It is common to distinguish between "internal exile", i.e., forced resettlement within the country of residence, and "external exile", which is deportation outside the country of residence. Although most commonly used to describe an individual situation, the term is also used for groups (especially ethnic or national groups), or for an entire government. Terms such as "diaspora" and "refugee" describe group exile, both voluntary and forced, and "government in exile" describes a government of a country that has been forced to relocate and argue its legitimacy from outside that country. Exile can also be a self-imposed departure from one's homeland. Self-exile is often depicted as a form of protest by the person who claims it, to avoid persecution or legal matters (such as tax or criminal allegations), an act of shame or repentance, or isolating oneself to be able to devote time to a particular pursuit. Article 9 of the Universal Declaration of Human Rights states that "No one shall be subjected to arbitrary arrest, detention or exile."

In some cases the deposed head of state is allowed to go into exile following a coup or other change of government, allowing a more peaceful transition to take place or to escape justice.

A wealthy citizen who departs from a former abode for a lower tax jurisdiction (a "tax haven") in order to reduce his/her tax burden is termed a "tax exile". Creative people such as authors and musicians who achieve sudden wealth sometimes find themselves among this group. Examples include the British-Canadian writer Arthur Hailey, who moved to the Bahamas to avoid taxes following the runaway success of his novels Hotel and Airport, and the English rock band the Rolling Stones who, in the spring of 1971, owed more in taxes than they could pay and left Britain before the government could seize their assets. Members of the band all moved to France for a period of time where they recorded music for the album that came to be called Exile on Main Street, the Main Street of the title referring to the French Riviera. In 2012, Eduardo Saverin, one of the founders of Facebook, made headlines by renouncing his U.S. citizenship before his company's IPO. The dual Brazilian/U.S. citizen's decision to move to Singapore and renounce his citizenship spurred a bill in the U.S. Senate, the Ex-PATRIOT Act, which would have forced such wealthy "tax exiles" to pay a special tax in order to re-enter the United States.
