"Small investors have entered the stock market, people have entered the crypto market. So, genuinely you may miss out on certain income to be shown. So, if your return filing last date is July-end and by December-end you can file a revised return. After that, you don't even have a chance to do it. The whole idea is, one, we give a chance to people if they realise they have made a mistake they can correct the mistake. But at the same time, if it comes to the notice of the tax department that taxes have not been paid, then action will follow. So once we start issuing notices, then you don't have this option (to file an updated return). If people start taking chances like that (by not filing the correct ITR originally), it will not work," he said.
