What is Public Provident Fund (PPF) & How Does it Work?


Public Provident Fund (PPF) is a premier, sovereign-backed long-term savings and investment scheme established by the Central Government of India in 1968. It combines complete capital safety with guaranteed compounding returns and unbeatable tax efficiency. Any Indian citizen (salaried, self-employed, or professional) can open a PPF account at any designated post office or commercial bank branch (such as SBI, HDFC, ICICI, PNB, or Axis Bank).

The Famous "5th of the Month" Interest Calculation Rule

Understanding how interest is computed is the single most valuable strategy for PPF investors. While interest is officially credited to your account once a year on March 31st, it is calculated on a monthly basis:

Monthly Interest = ( Lowest Balance between 5th and End of Month ) × ( Annual Rate ÷ 1200 )

What this means for your money:

  • Monthly Depositors: Always deposit on or before the 5th of every month. If you deposit on the 6th, that deposit will earn zero interest for the entire current month.
  • Yearly Lump-Sum Depositors: Always deposit your entire annual contribution (up to ₹1.5 Lakh) between April 1st and April 5th. This ensures your entire lump sum earns compounding interest for all 12 months of the financial year.

The Triple EEE Tax Status: 100% Tax-Free Wealth Creation


Under the Indian Income Tax Act, PPF is one of the very few financial instruments that enjoys prestigious EEE (Exempt-Exempt-Exempt) tax status under the Old Tax Regime:

1. Exempt on Investment (Sec 80C)

Deposits up to ₹1,50,000 per financial year qualify for direct tax deduction under Section 80C of the Income Tax Act.

2. Exempt on Accrued Interest (Sec 10(11))

All interest earned annually at 7.1% is completely exempt from income tax and does not need to be declared as taxable income.

3. Exempt on Maturity Withdrawal

The entire lump-sum maturity corpus withdrawn upon completion of tenure is 100% tax-free with zero capital gains tax.

15-Year Lock-in & 5-Year Extension Block Rules


A PPF account matures after 15 complete financial years from the end of the financial year in which the account was opened (effectively 16 calendar years). Upon maturity, subscribers can choose from three flexible pathways:

Option Action Required Key Financial Advantage
1. Complete Maturity Withdrawal Submit account closure form along with passbook. Receive 100% tax-free lump-sum proceeds transferred directly to your bank account.
2. Extension With Fresh Contributions Submit Form H within 1 year of maturity. Continue depositing up to ₹1.5L/year in 5-year blocks while earning 7.1% tax-free interest and Section 80C deductions. Allows 1 partial withdrawal up to 60% of balance per 5-year block.
3. Extension Without Fresh Contributions Default option if no form is submitted within 1 year. Existing corpus continues to compound at 7.1% tax-free interest indefinitely. You can withdraw any amount once per financial year.

Frequently Asked Questions


What is the current interest rate on Public Provident Fund (PPF) in India?

The current interest rate on Public Provident Fund (PPF) is 7.10% per annum. The Ministry of Finance reviews and notifies small savings interest rates on a quarterly basis. Once set, the interest is compounded annually and officially credited to the subscriber's account on March 31st of every financial year.

How is interest calculated in a PPF account (The 5th of the Month Rule)?

PPF interest is calculated monthly based on the lowest balance standing to the credit of the account between the close of the 5th day and the end of the month. Therefore, to maximize interest earnings for that month, deposits must be credited on or before the 5th day. If depositing a yearly lump-sum, depositing before April 5th ensures you earn interest for the entire 12 months.

Why does PPF enjoy EEE (Exempt-Exempt-Exempt) tax status?

PPF is classified under the prestigious EEE (Exempt-Exempt-Exempt) tax category in India: (1) Contributions qualify for deduction up to ₹1,50,000 under Section 80C, (2) Annual interest accrued is 100% tax-free under Section 10(11), and (3) The entire maturity corpus withdrawn after 15 years is completely exempt from income tax and wealth tax.

What are the minimum and maximum deposit limits for a PPF account per financial year?

A subscriber must deposit a minimum of ₹500 in a financial year to keep the account active. The maximum statutory limit is ₹1,50,000 per financial year across all PPF accounts held by the individual (including accounts opened on behalf of minor children). Deposits exceeding ₹1,50,000 do not earn any interest and are ineligible for Section 80C tax deduction.

What happens after the mandatory 15-year maturity of a PPF account?

Upon completing the initial 15-year tenure, you have three options: (1) Withdraw the complete tax-free maturity corpus and close the account, (2) Extend the account in blocks of 5 years with fresh contributions by submitting Form H within 1 year of maturity, or (3) Extend the account in 5-year blocks without fresh contributions, where the existing accumulated balance continues to earn 7.1% tax-free interest with annual withdrawal privileges.

When can I avail of a loan or partial withdrawal against my PPF balance?

You can avail of a loan against your PPF balance starting from the 3rd financial year up to the end of the 6th financial year (up to 25% of the balance at the end of the 2nd preceding year). Partial tax-free withdrawals are permitted from the 7th financial year onward (up to 50% of the account balance at the end of the 4th preceding year or preceding year, whichever is lower).

Can an individual open more than one PPF account in their name?

No, an individual is legally permitted to open only one PPF account in their own name. Opening joint PPF accounts is not allowed. However, a parent or guardian can open an additional PPF account on behalf of a minor child, but the combined total deposit in the parent's account and the minor's account cannot exceed ₹1,50,000 in a financial year.

Is premature closure allowed in a PPF account before the 15-year tenure?

Premature closure of a PPF account is permitted only after the completion of 5 full financial years under specific compassionate grounds: (1) Treatment of life-threatening diseases or serious ailments of the account holder, spouse, dependent children, or parents, (2) Higher education expenses for the account holder or dependent children, or (3) Change in residency status (becoming an NRI). A penalty of 1% interest rate reduction from the account opening date is levied on premature closure.
