Just one per cent of individuals, who declared their income in assessment year 2012-13, accounted for almost 20 per cent of the taxable income, according to government data on income tax released for the first time on Friday. Among corporates, however, this imbalance is starker, with a little more than 5 per cent of the companies accounting for a whopping 94 per cent of the taxable income. Detailed income tax data is now available as the Central Board of Direct Taxes has made public information on the total number of taxpayers in the country, income disclosed in IT returns by various category of taxpayers etc. "It is a big step towards transparency & informed policy making," Prime Minister Narendra Modi tweeted. The data shows that direct tax collections have fallen drastically in the last five years, growing at an average annual rate of 8.5 per cent between assessment years 2011-12 and 2015-16, compared to the 14.1 per cent over the previous five years.
