I have a minor daughter and I want to open a PPF account for her. I am also investing 1.5L in my own PPF. As I understand, the annual limit of my and my daughter's PPF will be 1.5L. 1. The lock in of 15 years is calculated from the day of opening of minor PPF or from the date she turns major. 2. If I deposit say 10,000 per year in the minor's PPF above the 1.5L in my own PPF, then will the account be deactivated or only savings interest will be given on that.

The 15-year period starts from the financial year of opening, not when the child becomes major. The ₹1.5 lakh limit is aggregate across your PPF and your minor child’s PPF, and any excess investment simply earns no benefit but doesn’t invalidate the account.
