As per the income tax laws, it is important to note that the income tax return (ITR) must be verified within 30 days (120 days earlier) of filing it. Thus, if you are using the physical method to verify your ITR (i.e., sending ITR-V to CPC- Bengaluru), then it is important to make sure that it reaches the income tax department on time. If ITR is not verified, it will be considered that ITR is not filed by you.
