ITR filing deadline today: How much can a one-day delay after 31 July due date cost if you have tax dues

The income tax return filing deadline is 31 July 2026, with over 5.4 million returns already filed. Missing this date brings late fees and interest. Gaurav Makhijani said, "even a delay of just one day after 31 July can trigger interest for a full month." Please file your returns soon.
