Road Transport and Highways Ministry is considering a Rs 4,000 crore overhaul of around 80 border check posts across the country to ensure seamless flow of goods ahead of the implementation of GST. An app to link check posts under state governments as well as the Centre is also in the works, the government has said. “The Ministry would be one of the the biggest contributors towards the GST regime. There are check posts under the state government as well as the Central.The government is keen to implement the biggest tax reform since Independence from April 1 next year and the Goods and Services Tax (GST) aims to iron out a multi-layered indirect tax system, subsume all other indirect taxes and usher in an uniform tax structure. It was conceptualised in 2006 under the United Progressive Alliance-1 government.The Minister said that once the GST is rolled out, it will facilitate the inter-state movement of goods and therefore, the need has been felt.
