Under GST law, states were guaranteed payment for any loss of revenue in the first five years of the GST implementation starting July 1, 2017. The shortfall is calculated assuming a 14 per cent annual growth in GST collections by states over the base year of 2015-16. States are promised compensation for any revenue shortfall till 2022, in case they go below the 14 per cent annual growth since the GST rollout in 2017
