If you do a paper filing, you

If you do a paper filing, you need to file it at chennai. I suggest to use efiling where you can upload your returns on the web and send a signed copy of the ITR-V (acknowledgment) over post to this address:
Income Tax Department – CPC,
Post Box No - 1,
Electronic City Post Office,
Bangalore - 560100,
