The GST bill, which has been approved by the Lok Sabha, is pending in the Rajya Sabha because of opposition to the bill in its current form by the Congress party. A constitutional amendment bill requires at least 50% attendance and support of two-third of those present and voting in the house. For the GST bill to become a law, the bill also needs to be approved by half the state assemblies after its passage in the parliament. GST, touted as the single biggest indirect taxation reforms since independence, will simplify and harmonise the indirect tax regime in the country. The GST seeks to create a seamless national market in the country by replacing plethora of state taxes and central taxes by one tax.
