Hi Jituraj,
As per my understanding, you are talking about the 12A from Provident Fund, right..
Form -12A is a consolidate statement of dues & remittance of all the employee whether Joinee or Resignee and it has to be submitted to Regional P.F office along with Form - 5&10, within 20 days of the close of the month..
Hope the above statement may clear you point..
Regards,
