Even after the deadline for filing income tax returns ended on August 31, the growth in taxpayers filing e-returns continued to grow robustly, and for April-September, a 65% growth was witnessed over the year-ago period, data from the Central Board of Direct Taxes (CBDT) showed. The growth in the April-August period was 70%. Moreover, the average tax paid by an individual filer came in at close to Rs 35,000 in H1, up from a little over Rs 27,000 in April-August. Industry experts said that the rise in the average tax paid was attributable to the second tranche of advance tax — 45% of the assessed advance tax was to be paid by September 15 — paid by larger assessees.
