You can withdraw full amount on maturity (15th year).
You can also do partial withdrawal of about 50% after 7th year (there are some rules that decide exact amount)
After 15 years you can withdraw full amount but if you dont and renew the account then on 16th year again 50% rule will apply and you will have to wait till 20 years. (i.e. another 5 years)
You can withdraw only once in a year.
PS: Looking at current market... I would say that do not withdraw money... PPF if safe investment and that too tax free.
