The final report of the Fifteenth Finance Commission maintains continuity in some areas, while making some major changes in others. The report was greatly anticipated — with some concern in many quarters — because the terms of reference provided to the Commission went further in straining federal norms than in previous iterations. The Commission has faithfully considered these fresh terms of reference, and in some cases minimised their impact. The most controversial such change in the reference was the instruction to shift from the 1971 Census to the 2011 Census when it came to determining allocations to the states. On the one hand, this might be considered a necessary updating of the formula, given the vast demographic changes in India since 1971. On the other hand, some states — in the south, in particular — objected, as they saw it as penalising those states that had successfully controlled their population growth in the period since 1971.
The Commission has indeed used the 2011 Census as a base, but it has also upped the proportion in the formula used to apportion taxes among the states devoted to “performance”. This has been done precisely to address the concerns raised by the southern states; the Commission in its official press release states that “while the Census 2011 population data better represents the present need of states, to be fair to, as well as reward, the states which have done better on the demographic front, [the Commission] has assigned a 12.5 per cent weight to the demographic performance criterion”. Overall, the Commission retained the vertical devolution percentage at 41 per cent of the divisible pool of taxes as it had been previously (net of the amount being given to the erstwhile state of Jammu and Kashmir). But this conceals at least one major change — the reduction in the total transfer.
