The 15th Finance Commission Chairman NK Singh on Friday said the Goods and Services Tax is an iconic taxation reform that will improve compliance. “GST was a far-reaching iconic reform related to sharing of resources between the Central and State governments. It is indeed a radical tax reform,” Singh said at the India Economic Forum Skoch event here. “Let it not be misunderstood when many critics have said that the GST is a failure. This is exactly not a failure, this in my view is an outstanding attempt to bring about a radical change in architecture of taxation which will have many multiplier gains in terms of having the simplicity of the tax structure,” he said.
