India's decade-long wait for a national sales tax that will create one of the world's biggest single markets could be almost over by July 1. As per economic affairs secretary Shaktikanta Das the Goods and Services Tax (GST) will be implemented by July 1 and not later as feared earlier on. "GST implementation is a huge one and that is going to be implemented by July 1. Both central and state governments are working on this," Das said. After the last GST meet, however, it was told that GST cannot be implemented by July 1.
