The government has recently made a big change regarding Income Tax Return (ITR). If your income is less than the basic exemption limit and you have not filed ITR till now, then it is not necessary that you will be able to do so in future also. It is possible that due to these changes, the Income Tax Department may impose a penalty on you for not filing ITR. That is why it is important to know about these changes. According to the changes made by the Income Tax Department, if a person has deposited Rs 50 lakh or more in his savings bank account in a financial year, then it is necessary for him to file ITR according to his income.
