Proper implementation of the Goods and Services Tax is a work in progress, Gita Gopinath, the Chief Economist of the International Monetary Fund said today. In an interview to NDTV, Ms Gopinath said, "The indirect tax revenues which have come in are weaker than were expected, which is partly a reflection of how it was rolled out and the implementation issues with that and that would continue to have to be fixed." Agricultural distress in India is another key area that the IMF is looking at.
