The income and capital tax treaty and protocol between the United Kingdom and Slovenia, signed on 13 November 2007, entered into force on 11 September 2008. In the United Kingdom, the new treaty generally applies from 1 April 2009 for corporation tax purposes and from 6 April 2009 for income and capital gains tax purposes; in Slovenia, the treaty generally applies from 1 January 2009. From these dates, the new treaty generally replaces the UK-former Yugoslavia income tax treaty of 6 November 1981 in relations between Slovenia and the United Kingdom.
