"The total number of taxpayers (corporates, firms, Hindu undivided families among others) showing income of above Rs 1 crore has registered a sharp increase.
"While 88,649 taxpayers had disclosed income above Rs 1 crore in assessment year 2014-15, the figure was 1,40,139 for AY 2017-18, which is a growth of about 60 per cent," the CBDT said.
Similarly, it said, the number of individual taxpayers disclosing income above Rs 1 crore had increased during the same period from 48,416 to 81,344, which translated into a growth of 68 per cent.
CBDT Chairman Sushil Chandra said these numbers were a result of putting in a number of legislative, informative and enforcement efforts by the tax department over the last four years.
The data also added that a growth of more than 80 per cent was registered in the number of returns filed in the last four financial years -- from 3.79 crore in 2013-14 to 6.85 crore in 2017-18.
