How to extend my PPF account after 15 years?

[Madhura]

Thanks for your prompt reply. I have one more query -
If I extend it for another five years, can I close this extended PPF account in the next one year (i.e. in 16th year) and withdraw all the amount?

Yes, you can do that. If you are opting to subscribe for the extension of another 5 years, you will be eligible to make partial withdrawals. With following conditions to be met –
1- The partial withdrawals should not be exceeding ONE every year.
2- The total of the withdrawals, during the 5 year extension block period , shall not exceed 60 percent of the balance at his credit at the commencement of the said period.
