Dear ,

The Assessing Officer (Income Tax Deptt) have power to rectify the challan, as you have mentioned wrong AY. You should intimate to your Assessing Officer regarding said mistake and request  to rectify the Challan. After rectification you should go for rectification U/s 154 for reassessment.

AGREE WITH ABOVE...

YOU NEED TO APPROACH YOUR JURISDICTIONAL ASSESSING OFFICER TO GET THE RETURN RECTIFIED.

ALSO AS A MATTER OF PROCEDURE PROVIDE THEM WITH DETAILS OF A.Y. 11-12 AND A.Y. 12-13 TO PROVE THAT THE TAX PAID CHALLAN IS NOT CLAIMED TWICE.

ALSO THE OFFICER MAY ASK FOR AN AFFIDAVIT - AGAIN AS A MATTER OF PROCEDURE.

SO KINDLY APPROACH YOUR JURISDICTIONAL ASSESSING OFFICER

HI ALL

BUT THE RETURN IS FILED ELECTRONICALLY.

you can call banglore cpc on 18004252229 and ask them to transfer the case to local jurisdictional officer.

Also you can approach local officer, he can also ask for case to be transfer from banglore to his ward.

but you need to put time and efforts from your side.

i hope this helps you.
