Registration and reporting obligations require banks to obtain ITDREIN and electronically submit Form V with a digital signature. Authorised banks must register on the Income Tax e filing portal to obtain an ITDREIN (non deactivatable) and then register a designated director and principal officer via emailed activation links and OTPs. Banks must prepare Form V as an XML using the prescribed schema and utility from the portal and submit it electronically: the designated director logs in with ITDREIN and PAN and files Form V using his Digital Signature Certificate to enable next working day departmental verification.
