Vice President Mahamadu Bawumia has said that he will reduce the withholding tax on gold mining from 1.5 percent to 1 percent when voted into office next year. Dr Bawumia is confident this will improve on tax collection and help shore up government revenue. He was speaking at the opening of a new refinery 'The Royal Ghana Gold Refinery' which is projected to accrue over $10 billion before the end of this year. Dr Bawumia recalled the challenges in revenue mobilization as a result of increase in withholding tax which is 1.5 percent. He expressed concern that this has resulted in tax avoidance by some operators in the gold mining business.
