It was a desperate move to bridge the fiscal deficits of the states that may now boomerang on the total revenues flowing into their coffers. In January, when the states introduced a uniform sales tax under four slabs (at 4, 8, 12 and 16 per cent), apart from two special rates (at one per cent for bullion and gold and 40 per cent for liquor), they did so with trepidation and a little greed. Fearing that they could lose out on revenues under the new simplified slabs, they went ahead and moved most items to the highest rate being charged by any of the states, rather than settling for average rates.
