WATCH LIVE: The GST Rollout ceremony in Central Hall in Parliament

After 17 tumultuous years, a nationwide Goods and Services Tax (GST) will roll out from midnight tonight, overhauling India's convoluted indirect taxation system and unifying the USD 2 trillion economy with 1.3 billion people into a single market. GST, which will replace more than a dozen central and state levies like factory-gate, excise duty, service tax and local sales tax or VAT, is India's biggest tax reform in the 70 years of independence and will help modernise Asia's third largest economy.
