PPF Explained Simply: Slabs, Lock-in & Tax-Free Growth

Published: 2026-05-28

The Public Provident Fund (PPF) is an incredibly popular savings-cum-investment instrument introduced by the National Savings Institute in 1968. It is designed to mobilize small savings by offering reasonable returns combined with high tax safety.

What is PPF?

PPF is a government-backed scheme open to all Indian citizens (salaried, freelancers, or homemakers). It offers complete safety of principal, an attractive interest rate (currently 7.1% compounded annually), and stellar tax exemptions.

The EEE Tax Advantage

PPF is one of the very few instruments in India that carries the coveted **Exempt-Exempt-Exempt (EEE)** tax status:

  • Exempt (Contribution): Yearly deposits up to ₹1.5 Lakhs are deductible under Section 80C.
  • Exempt (Accumulation): Annual interest earned is completely exempt from tax.
  • Exempt (Withdrawal): The final maturity amount after 15 years is 100% tax-free.

PPF Lock-in and Extensions

PPF has a maturity term of 15 years. However, after 15 years, you can extend the account indefinitely in blocks of 5 years, either with or without making additional contributions, maintaining the tax-free compounding growth.

Tips to Maximize PPF Interest

To maximize interest, always deposit your PPF contribution **before the 5th of the month**. Bank interest is calculated on the minimum balance between the 5th and the last day of the month, so depositing by the 4th ensures you earn interest for that entire month!
