I have a PPF account in my son’s name and another PPF Account in my name was closed 3 years ago . Although i have been getting interest in My son’s account at least that is being mentioned in the booklet .But recently i came to know that both accounts combined will get interest upto 70,000 (from this year 1,00,000 ) . Effectively since this is the only saving scheme i invested in , i made payments upto maximum amount that is 70,000 . Will my son get interest or that will be deducted when he withdraws the entire amount on maturity from ppf
