I am a Manpower HR Executive in an office. The PF annual return for 2011-2012 has not yet been submitted in my office. Now, my boss has asked me to do this work, but I don't know what needs to be filed. I have prepared FORM 3A & 6A. Please tell me if this data is sufficient for submission. Can I go to the PF office with this data for the annual return? Please help me out.
