I am a British citizen PIO, now a tax resident in India. I have a PPF account which was started as a resident Indian and is due to mature in March 2018. Will I be able to extend my account for the further 5 years?
You can extend your PPF account for further 5 years period. Even if you were to become an NRI again during the extension, the PPF rules allow you to operate accounts opened when your status was of a resident Indian. However, please note that as a tax resident, you can no longer hold NRO/NRE accounts; all your bank accounts should be resident Indian savings bank accounts.
