Let’s start with a small story in this regard.
Mr. A, a mid-level software engineer, felt incredibly confident about his tax return last year. He had uploaded his Form 16, claimed his standard deduction, and proudly hit the submit button on the income tax portal. What he decided not to include was the ₹25,000 interest he earned from a couple of old Fixed Deposits (FDs) and a quick ₹50,000 profit he made selling shares on a popular trading app to fund a quick vacation. In his mind, these were minor, fragmented amounts. Who would possibly notice a few casual stock trades or interest accumulating in a secondary bank account?
