May 31 (SeeNews) - Bosnia's top international peacekeeper extended on Thursday the mandate of the governing board chairman of the country's Indirect Taxation Authority (ITA) by six months to enable the smooth transition to a local chairman.New Zealander Peter Nicholl, former governor of Bosnia's central bank, was to be replaced by a native chairman on June 1, but since the relevant domestic authorities failed to appoint such, the High Representative in the war-divided state extended Nicholl's mandate to January 13, 2008, the Office of the High Representative said in a statement.Bosnia launched single collection of indirect taxes, customs revenue and road tolls in January 2005, stripping the post-war entities, the Muslim-Croat Federation and the Serb Republic, of this power in favour of ITA in a bid to centralise the divided fiscal system. ITA has been collecting also a flat 17% VAT since January last year. The extension of Nicholl's mandate is expected to allow ITA to focus on strategic policy issues and on the future efficient supervision of the authority."The extension also allows the ITA to focus on establishing the administrative capacity in the ITA Governing Board necessary for the transition to a local chairman," the statement added.ITA fulfilled its plan for 2006 yet in November, having collected 3.5 billion marka ($2.39 billion/1.78 billion euro) in revenue in the first 10 months of the year.
