In the biggest tax reform since Independence, the national sales tax or GST Bill was today approved by the Rajya Sabha to replace a raft of different state and local taxes with a single unified value added tax system to turn the country into the world's biggest single market.
The 66-year-old Constitution, which gives power to Centre to levy taxes like excise, and empowers states to collect retail sales taxes, was amended though the 122nd Constitution Amendment Bill.
The legislation was approved by the Upper House with 203 votes in favour and none against, after a seven-hour debate.
