Rio asked to pay an additional A$447m in tax

Mining major Rio Tinto is preparing to challenge amended assessments issued by the Australian Commissioner of Taxation outlining additional taxes due of A$447-million – A$379-million plus interest of A$68-million – for the calendar years from 2010 to 2013. This is in addition to the A$25.5-billion of taxes and royalties Rio Tinto paid in Australia during that period.
