Ans: Individuals can hold only one PPF account under their name. However, a person can operate his minor son’s account on his/her behalf.  The tax exemptions you will receive will only be up to Rs.1.5 Lakh per year under Section 80C. So the investment you make under your name and your son’s PPF account should not exceed the threshold of Rs.1.5 lakh to be eligible for tax benefits.
