AS India prepares to launch its biggest tax reform since independence in 1947, businesses and citizens across the country are bracing for economic chaos.

At midnight on July 1, Prime Minister Narendra Modi will formally usher in the country's new goods and services tax. First proposed in 2006, the GST will subsume more than a dozen state and central levies into one tax, unifying this country of 29 diverse states and 1.28 billion people into a single market for the first time.
