Today, the tax department said that the ITR software was rectified on 1st August itself to remove the error due to incorrect computation of interest. It also said that taxpayers have been advised to use the latest version of the ITR preparation software or file online. "If, by any chance, someone has already submitted the ITR with such incorrect interest or late fee, the same will be correctly calculated while processing at CPC-ITR and the excess amount paid, if any, will be refunded in the normal course," the department wrote on Twitter.

Earlier this week, some chartered accountants said that users have complained of technical issues on the site from the very first day and that not everything has been fixed even after a week. Taxpayers are unable to view past e-filed returns and many features/ facilities continue to be marked 'coming soon'.

Finance Minister Nirmala Sitharaman too has raised issues with new return filing software in the past. Soon after the launch of the new software, the finance minster said: "The much awaited e-filing portal 2.0 was launched last night 20:45hrs. I see in my TL grievances and glitches. Hope @Infosys & @NandanNilekani will not let down our taxpayers in the quality of service being provided. Ease in compliance for the taxpayer should be our priority."

Infosys was in 2019 awarded a contract to develop the next-generation income tax filing system to reduce processing time for returns from 63 days to one day and expedite refunds.
