A Tax Information Exchange Agreement (TIEA) between the United Kingdom and The Bahamas was signed 29 October 2009.
The new TIEA with The Bahamas will enable the UK and The Bahamas to exchange information to OECD and international tax standards to ensure that the right amount of tax is paid in each country in the future. The Agreement will come into effect as soon as each government has completed the necessary procedures to give effect to it under its domestic laws.
