The all powerful GST Council comprising state finance ministers and headed by Union Finance Minister has pruned the highest 28 per cent slab by cutting tax rates on 191 goods over the last one year, including ACs, digital cameras, video recorders, dish-washing machines and automobiles.
There are just 35 items left in the highest tax bracket.
When the 28 per cent tax rate was imposed on certain items under GST, there was a political reaction against it, and the GST Council responded by "really whittling down...quite substantially" the number of products in that slab, Subramanian said in an interview to Rajya Sabha TV's 'To The Point' programme.
"I am very confident that over the next year so that 28 per cent hopefully will be virtually a shell hollow shell," he said.
The CEA also said that a lot of effort and time was devoted to the simplifying the burden on small and medium enterprises.
To a question regarding lateral entry into government, he said: "I am lateral entrant myself. So how can I argue against that?"
"You need specific expertise. I think the lateral entry is a good thing. Govt needs more talent than silicon valley," said Subramanian, who would be leaving the finance ministry on July 30. He had joined the ministry in October 2014.
Subramanian further said he had a wonderful working relationship with all colleagues both in the ministry and the government and "a very close working relationship with PMO".
When asked about what he would be doing after leaving the Ministry, Subramanian said he would go to Harvard and get back to research and writing.
On contesting elections, he said: "I will be an utter failure in politics".
