"The reduction in corporate tax rate is expected to make India competitive, it is expected to make India as an attractive destination for investments, for both domestic and for global investors," he said at an interactive session of CII here.
"With regard to taxation structures we needed to be competitive...India can be competitive only when we move towards a corporate tax of 25 per cent. It is not possible for us to do (it) in a single year," he added.
"The gradual reduction in corporate tax rate has to be accompanied by the phasing out of exemptions. Government did not want to take any investor, any industry which have already invested money by surprise.

"When I say that we are eliminating exemptions, you will agree that bulk of tax litigations are linked to various kinds of incentives or exemptions. So at one stroke we are also eliminating a huge area of tax dispute, tax litigation for the tax payer...," he said.
