PPF provides tax deductions on the amount invested u\/s 80C up to Rs 1,50,000 in a financial year and the interest as well as the maturity amount are also tax free, which makes it an ideal tax-saving instrument of exempt, exempt, exempt (EEE) category. PPF investments are secure as it carries sovereign guarantee and are also fully protected as it can\u2019t be attached under any order or decree of a court in respect of any debt or liability. A PPF account may be opened by any earning individual for self or his\/her child for a tenure of 15 years, which may be extended for a block of five years any number of times on maturity. Loan facility is available on PPF from the third year of opening the account to the sixth year, while option of partial withdrawal is there from seventh year onwards. The newly-launched DOP eBanking facility makes the contribution and withdrawal facilities available online. 2. Sukanya Samriddhi Yojana: The government has launched the Sukanya Samriddhi Youjana (SSY) as part of its 'Beti Padao, Beti Bachao' or 'save the girl child' campaign, under which, natural or legal guardians may open an account for their girl child till she turns 10 years old. The account is opened for 21 years, in which contributions up to Rs 1,50,000 may be made in a financial year for 15 years.
