Premier of the Cayman Islands William
McKeeva Bush to lead an independent task force to examine new revenue options for the
Cayman Islands Government. The Cayman Islands has no direct taxation although that may change as a result of an agreement with the United Kingdom
Foreign and Commonwealth Office. The UK FCO allowed the Cayman Islands Government to borrow additional funds to meet capital and operational expenses as long as the Government agreed to look at ways in which to increase and stabilize its revenue base—direct taxation being the preferred solution. == See also ==
