Talking to reporters at the Assembly premises, Kumar said there were lots of benefits of the GST, which was passed by the Rajya Sabha yesterday.
"If need arises, we will call a special sitting of the Bihar Assembly to approve the GST legislation from the state," Kumar said and expressed hope the GST would come into effect from April 1, 2017.
Kumar, who is also national president of JD(U), has expressed support for the GST Bill from the beginning and had conveyed this to Finance Minister Arun Jaitley during a meeting with him recently.
The Constitution (122nd Amendment) Bill, 2014 on GST has already been passed by the Lok Sabha.
The GST Bill needs to be approved by Assemblies of at least half of the total 29 states.
