The Constitution (122nd Amendment) Bill, 2016, for introduction of the GST in the country was accorded assent by the President on September 8 and the same has been notified as the Constitution (101st Amendment) Act, 2016.

"GST is the biggest game changer. But it is also a challenge. We are working overtime to make it happen from April 1, 2017," Sinha said at the Chief Secretaries' Conclave organised by industry chamber PHDCCI.

Government wants to implement the tax reform from April 1 next year so as to ensure a smooth rollover to the changed tax structure from the beginning of the new fiscal and to avoid mid-year alterations. Sinha assured the gathering that the GST and other path breaking reforms that the government has committed to its people will be implemented as promised.

"A silent revolution is happening and despite teething problems, India would move on to accomplish the objectives and targets set in by the government in all sectors of economic activities with increased participations of all stakeholders to further improve the spirit of governance," he said.

The infrastructure sector - roads, civil aviation, energy, conventional and non-convention, power, petroleum and railways - have improved their performance as per targets, he said adding the civil aviation sector has begun to grow at the rate of 20 per cent, posing a serious challenge to railways in terms of traffic.
