For the October–December 2026 quarter, PPF earns 7.1% a year. The government sets this rate every quarter.

PPF interest and the maturity amount are fully tax-free. In the old tax regime, deposits also get the 80C deduction; the new regime has no 80C deduction, but the interest stays tax-free.

The account matures after 15 years and can then be extended in blocks of 5 years. After 5 financial years, partial withdrawals are allowed under some conditions.
