I had quoted a wrong PAN on ITR while e-filing it for A.Y.2011-12. co-incidently the name and DOB of both the assesses are same as per IT database. so the software accepted the return with wrong PAN. now at the time of filing return for A.Y.2012-13 i came to know about my mistake. So please help me out, how can i deal with this. what is the right procedure to rectify this mistake.
