Public Provident Fund (PPF) Rules, Interest & Tax Benefits (FY 2026-27)

The Public Provident Fund (PPF) is a 15-year statutory savings scheme backed by the Government of India that currently offers a 7.10% annual interest rate compounded annually with sovereign security. PPF carries coveted Exempt-Exempt-Exempt (EEE) tax status, meaning contributions (up to ₹1.5 Lakh under the Old Regime), accrued interest, and maturity proceeds are 100% tax-free.

To maximize interest earnings, depositors should deposit funds on or before the 5th of every calendar month, because interest is calculated on the lowest balance between the close of the 5th day and the end of the month.

The Critical "5th of the Month" Rule Explained

Under the Public Provident Fund Scheme Rules:

  • Interest is calculated every month on the lowest balance in the account between the close of the 5th day and the last day of the month.

  • Although computed monthly, interest is officially credited to the account balance once a year on March 31st.

  • Actionable Rule: If you deposit your contribution on the 6th of the month, you lose interest on that sum for that entire month. Always transfer PPF funds between the 1st and 5th of the month.

    Worked Example: Investing ₹1.5 Lakh Annually for 15 Years

    If an investor deposits the maximum allowable limit of ₹1,50,000 before April 5th every year at a constant 7.10% interest rate:

  • Total Principal Invested (15 years): $15 \times ₹1,50,000 = \mathbf{₹22,50,000}$

  • Total Tax-Free Interest Earned: $\mathbf{₹18,18,209}$

  • Maturity Amount (End of Year 15): $\mathbf{₹40,68,209}$
  • By extending the account for two additional 5-year blocks (25 years total), the maturity corpus compounds to over ₹1.03 Crore completely tax-free.

    Frequently Asked Questions

    Can an NRI open a PPF account?

    Non-Resident Indians (NRIs) cannot open new PPF accounts. However, if a resident opened a PPF account prior to becoming an NRI, they may continue contributing until maturity on a non-repatriable basis, but cannot extend the account for 5-year blocks thereafter.

    Can a PPF account be attached by a court order?

    No. Under Section 15 of the Government Savings Promotion Act, a PPF account balance cannot be attached by any decree or order of any court in respect of any debt or liability incurred by the account holder.
