Public Provident Fund (India)
The Public Provident Fund (PPF) is a savings-cum-tax-saving instrument in India, introduced by the National Savings Institute of the Ministry of Finance in 1968. The main objective of the scheme is to mobilize small savings by offering an investment with reasonable returns combined with income tax benefits. The scheme is offered by the Central Government. Balance in the PPF account is not subject to attachment under any order or decree of court under the Government Savings Banks Act, 1873. However Income Tax & other Government authorities can attach the account for recovering tax dues. The 2019 Public Provident Fund Scheme, introduced by the Government on 12 December 2019, resulted in the rescinding of the earlier 1968 Public Provident Fund Scheme. Eligibility
Individuals who are residents of India are eligible to open their account under the Public Provident Fund, and are entitled to tax-free returns. Non resident Indians
As of August 2018, according to the Indian Ministry of finance (Department of Economic Affairs), NRIs (Non resident Indians) are not allowed to open new PPF accounts. However, they are allowed to continue their existing PPF accounts up to its 15 years maturity period. An amendment to earlier rules allowing NRIs to invest in PPF was proposed in the 2018 Finance Bill, but has not yet been approved. In October 2017, a notification was passed by the Ministry of Finance regarding an amendment to the PPF scheme of 1968, which would deem a PPF account closed from the day a person became a non resident. This led to much confusion. Subsequently, the ministry issued an office memorandum in February 2018 keeping the above notification in abeyance until any further order on this matter, thus the situation remained unchanged. Investment and returns
A minimum yearly deposit of ₹500 is required to open and maintain a PPF account. A PPF account holder can deposit a maximum of ₹1.5 lacs in his/her PPF account (including those accounts where he is the guardian) per financial year. There must be a guardian for PPF accounts opened in the name of minor children. Parents can act as guardians in such PPF accounts of minor children. Any amount deposited more than ₹1.5 lacs in a financial year will not earn any interest. The amount can be deposited in lump sum or installments per year. However, this does not mean a single deposit is made once a month. The Ministry of Finance, Government of India announces the rate of interest for PPF account every quarter. This interest is compounded annually and is paid in March every year. Interest is calculated on the lowest balance between the close of the fifth day and the last day of every month. Interest rates

Annual contributions qualify for tax deduction under Section 80C of income tax as per the old Tax regime. The tax benefit is capped at ₹1.5 lacs per financial year. PPF falls under EEE (Exempt, Exempt, Exempt) tax basket. Contribution to PPF account is eligible for tax benefit under Section 80C of the Income Tax Act in the old Tax Regime. Interest earned is exempt from income tax and maturity proceeds are also exempt from tax. According to R.K. Mohapatra, General Manager-Finance, IRCON International, and author of the award-winning book ‘Retirement Planning: A Simple Guide for Individuals’, in the falling interest rate era, investment in PPF make senses for people who are in higher income tax brackets because of the advantages of exempt-exempt-exempt (EEE) scheme, which means they get tax deduction under Section 80C when they invest, and the accrual of interest as well as withdrawal is completely tax-free.
