A large number of tax slabs agreed upon by the GST Council may however dilute some of the benefits of the GST system, but preliminary understanding of the proposed tax rates suggests broadly neutral impact for sectors, said the report by Kotak Institutional Equities.
"The structure aims to minimise the impact on CPI inflation and revenues of governments as the proposed GST rates are similar to current 'overall' rates for most goods," the report said, adding that "hence, we see limited impact on overall government revenues".
"We estimate 15-25 bps impact on inflation from higher tax rates on 15-20 per cent of the CPI basket (including some services) with no impact on around 50 per cent of the CPI basket (food, education, healthcare) which are zero-rated and the rest with broadly unchanged rates," the report said.
It further noted that the April 1, 2017 deadline for its implementation seems "achievable" and the possibility of timely implementation of the GST regime has strengthened.
Moreover, IT infrastructure will also have to be in place by December 2016 for testing and integration before next April.
