The Public Provident Fund (PPF) is a long-term savings scheme offered by the Government of India. It encourages individuals to save for retirement while providing tax benefits. The scheme has a minimum investment requirement and a fixed interest rate, which is reviewed quarterly. PPF accounts have a maturity period of 15 years, but they can be extended in blocks of five years. Investors can open a PPF account at various banks and post offices across India. Contributions to the fund are eligible for tax deductions under Section 80C of the Income Tax Act. The interest earned is tax-free, making it an attractive option for long-term savings.
