Finance minister Arun Jaitley on Thursday said the Centre was trying earnestly to build a consensus with the states on the sticky issue of sharing of administrative control on assessees to ensure that the April 1 deadline for rolling out the goods and service tax (GST) was met. “We are making all efforts to introduce GST from April 1, 2017. GST has to be implemented latest by September 16, 2017, and if it is not implemented by then, states will not be able to collect their share of taxes, and hence, there is not enough scope to further delay the decision,” Jaitley said at an economic editors’ conference here. The minister was referring to the GST Constitutional Amendment, which has a provision in this regard.
