Technical glitches continue to bedevil the modified income tax website on the second day — prompting finance minister Nirmala Sitharaman to tweet: “Hope Infosys and Nandan Nilekani will not let down our taxpayers in the quality of service being provided.”

Sitharaman said she had been besieged by complaints from taxpayers and chartered accountants who said the website wasn’t working.

Later at night, Infosys chairman Nilekani tweeted: “We have observed some technical issues on day one, and are working to resolve them. Infosys regrets these initial glitches and expects the system to stabilise during the week.”

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

In a tweet hunkashish123 said, “What milestone? Website is not working. First develop it properly after launching the portal. Recruit new people in the department and penalise the developer.”

Bimal Jain, a chartered accountant, said “The success of the new income-tax portal depends on the smooth transition from the old portal and the working of the new one. At present, the site is not working smoothly and the taxpayers were not able to log into the portal”.

He said the taxpayers would have to re-register their digital signature certificates, which could have been automatically transitioned from the old portal.

“From the past experience of GSTN Portal, the government should have taken adequate measures to ensure that the site is able to handle traffic and no technical glitches are faced by the taxpayers.”

On Tuesday morning, Sitharaman took to Twitter to announce the launch of the new portal www.incometax.gov.in, saying that the “important milestone to make the compliance experience more taxpayer-friendly” went live at 2045 Hrs on Monday. But, soon, her timeline was flooded with user complaints.

Since the new site went live, several taxpayers complained of problems during logging in to the portal. The taxpayers could not link their mobile phone numbers to the portal.
