Entering mail-Id of anyone other than the taxpayer himself/herself is an incorrect practise as the Income-tax department may send updates, notices or intimations.
IT Department is emphasizing on use of mail-ids for sending notices, intimations etc. instead of physically copies. Also, when you file your return, you receive your ITR-V acknowledgement on your registered email-id. Make sure, that the email-id provided by you is active.
Make sure that you take care of such small things in order to avoid any hassles or huge tax demands in future. Do not hesitate to provide your personal email-id to us while filing your income tax returns with myitreturn. It is very safe and also there are no disturbing alerts from our side.You data is absolutely secure with us.
