Repatriation tax holiday: A repatriation tax holiday is a tax holiday specifically directed towards individuals and businesses in one country who repatriate to that country income earned in other countries.  The theory supporting such an action is that multinational companies headquartered in one country, but which earn income in a second country will be unlikely to bring income from the second country back to their home country if high taxes will be assessed on this income when it is brought back.  By allowing those companies to bring income back to the home country at a reduced tax rate, money will be injected into the economy of the home country that otherwise would remain in the second country.
