UK India Business Council experts analyse what GST will mean for businesses worldwide and the challenges it faces in this 'India Investment Journal' special report. The introduction of GST will be a game changer for India, its economy, and for Mr Modi himself. When surveyed last October, 50 per cent of UK India Business Council members cited GST as the single most important reform they wanted the Modi Government to enact. The mood, now, is naturally positive. Perhaps some of that positivity is because not everyone expected it to happen. For years, political debate around GST in India has been, to say the least, fractious. BJP PM, Atal BIhari Vajpayee, started the ball rolling in 2000 when he set-up an empowered committee to develop a model for GST. The Congress-led governments advanced the agenda between 2004 and 2014, and actually set a target date of April 2010 for the GST's introduction. It proved impossible, though, to get political consensus. Now, 16 years on, an agreement has been reached. Credit for this has to be spread widely. Mr Modi and finance minister Jaitley have been determined, patient and, latterly, effective in building consensus. Other political leaders have played their part too, both within Congress and across the regional parties that dominate in many states. Political leaders have set aside opposition for the sake of opposition, and taken a big decision that will improve India's business environment and therefore lead to higher growth and faster job creation. With 1 million people joining the workforce every month, India needs this growth. So why is GST such a game changer The GST is, according to JP Morgan's Sajjid Chonoy, a 'Free Trade Agreement between India and itself'. It will remove the current web of taxes and tariffs between states, making it much easier to do business across the whole country. India will become a single market for almost all goods and services. Virtuous Cycle It is estimated that the Indian economy will gain $15 billion a year as a result of GST. It will make manufacturing more competitive, which will increase investment, grow exports, and create jobs. More people entering the workforce will drive up consumption, which will increase production and so on. This virtious cycle should also be strengthened with lower prices. As the UK India Business Council's recently published 'Modi Government Progress Report' stated, GST will improve the ease of doing business in India in a number of ways, including:
