Upon reaching the 15-year maturity of a Public Provident Fund (PPF) account, investors face several options: full withdrawal, account extension, or phased withdrawals. A full withdrawal allows access to the entire corpus, which is tax-free under India's Exempt-Exempt-Exempt (EEE) category, making it suitable for those needing immediate liquidity for significant expenses like home purchases or education. Alternatively, extending the account in five-year blocks enables continued tax-free interest and contributions up to ₹1.5 lakh (approximately $1,800 USD) per year, appealing to long-term investors. Phased withdrawals allow for liquidity while keeping the account active, though only one withdrawal is permitted per year. Investors should consider their financial goals and liquidity needs when making this decision, as partial withdrawals can also be made after five years of account operation, providing flexibility in managing funds.
