Users say that the Income Tax department’s portal was slow, froze or threw up errors on Monday when millions logged in to file returns, prompting the deadline to be extended by a day.

The portal was under maintenance till 2:30 am on Tuesday to stabilise services.

“Taxpayers should avail of this extra day to submit their tax returns in time as missing the deadline may have serious repercussions. Apart from a penalty of up to Rs 5,000 and 1 per cent interest per month on unpaid taxes, late filing leads to losing the ability to carry forward losses, switch to a favourable tax regime, and could delay refunds or increase the risk of scrutiny,” said Aarti Raote, partner at Deloitte India.
