New Delhi: Warning corporates not to take unfair advantage of the liberalised tax environment, Finance Minister Arun Jaitley on Friday said the world is moving towards a more transparent regime that would remove the veil of secrecy from unlawful transactions.

"I think, for every assessee, every person in the commercial business also, it is a judgement call that in a liberal economic environment of reasonable and lower taxation rates, 'go straight'," he said at the foundation day celebrations of the Enforcement Directorate.
