Ppf account

Can i open 2 accounts in PPF on in my own name and second as a guradian of my child and deposit 2 lakhs . I will take exemption of 1 lakhs but i hope this 2 lakhs will carry an interest 8.8 % or only i can deposit 1 lakhs jointly in both accounts.

Secondly i want to know this 1 lakh limit is for interest income or i can deposit more than 1 lakh and intestest will be given for 1 lakh only just for clarification

You can open the PPF a/c in your name & as a guardian of your child.  In each account you can deposit upto 1lacs only, but overall deduction u/s 80c wud be 1lacs only.

You can deposit only upto 1lacs during an F.Y.  Interest would not be considered as an deposit & will be treated separately.
