If you have missed all your deadlines of the regular filing of the income tax return (ITR), you must consider filing an updated income tax return (ITR-U), or in case of previously filed ITRs, you realise you have made any mistakes and they require revisions, you should take the recourse of filing ITR- U. “It does come with additional costs depending on timelines, but it ensures compliance and thereby can prevent notices for assessments/ future investigations,” says Ritika Nayyar, partner, Singhania & Co.
