Dear Mr. H. Singh,
1. No need to make any paper work or CD for yearly PF return for 2012-13 as it is already in the electronical form. System will take care of everything, if you uploaded ECR files every month from March 2012 to Feb. 2013.
2. Coming to your specific query of Form 2 i.e. Nomination form - Earlier form 2 was submitted to Regional PF office along with Form 9 & Form 10 every month and they would refer the same in case of member death.Now every thing has been made electronically amd PF office is not asking form 2. However, the same will be filled in during new member joning and kept ready with u because if any conflict arises between members family while claim process after his / her death (between wife & mother or between two wifes with regards to the legal heir for getting PF & Pension amount), form 2 will be helpful to you to solve the issue. Form 2 will only be the office internal record and no need to submit to PF office. It will only be required at conflict time as and when RPF office asks.
