PPF Account Guide: Interest, Rules, Withdrawals and Tax Benefits
The Public Provident Fund is one of the few investments in India that is entirely tax-free at every stage: contributions, interest, and maturity proceeds. That EEE status, combined with government backing and a compounding interest rate that beats most bank fixed deposits over the long run, makes PPF a cornerstone of conservative wealth-building. This guide covers exactly how the account works — numbers, rules, and the traps most people miss.
What EEE Status Actually Means
EEE stands for Exempt-Exempt-Exempt — the three stages at which the Indian tax authority could theoretically tax your money:
- Contribution (E1): Deposits up to ₹1.5 lakh per financial year qualify for deduction under Section 80C of the Income Tax Act, reducing your taxable income directly.
- Interest earned (E2): The annual interest credited to your PPF account is fully exempt under Section 10. You do not declare it as income, and no TDS is deducted — ever.
- Maturity proceeds (E3): The entire corpus you withdraw at maturity — principal plus all compounded interest — is tax-free.
Compare this with a bank FD: interest is taxable every year at your slab rate, and TDS is deducted if annual interest exceeds ₹40,000. On a 15-year horizon, the effective post-tax difference in real returns is substantial.
The 15-Year Lock-In: How It Actually Works
PPF has a mandatory 15-year tenure, but the counting starts from the end of the financial year in which you open the account — not the date of opening. If you open an account in December 2024, the clock starts from March 31, 2025, and your account matures on March 31, 2040.
This has a practical implication: opening an account early in the financial year (April–May) maximizes your effective tenure. Opening in February or March costs you almost a full year of the lock-in clock, making the real lock-in closer to 16 years.
Minimum deposit: ₹500 per year. Failing to deposit at least ₹500 in any year makes the account dormant. Reactivating it costs ₹50 per dormant year plus the minimum deposit for each missed year.
Maximum deposit: ₹1.5 lakh per financial year, across all PPF accounts in your name (you can hold only one account, plus one on behalf of a minor).
How Interest Is Calculated — With a Worked Example
Interest is calculated on the lowest balance between the 5th and the last day of each month, then credited to your account annually on March 31. This is the most important mechanical detail most investors miss.
If you deposit ₹1.5 lakh on April 3, it qualifies for interest that month. If you deposit on April 6, the April balance used for calculation is ₹0 — you lose one month of interest. Always deposit before the 5th of April if you want full-year interest.
Worked example (illustrative, using a typical rate of 7.1% per annum):
- Opening balance on April 1: ₹5,00,000
- Deposit on April 3: ₹1,50,000
- Balance for April calculation: ₹6,50,000
- Monthly interest credited to notional account: ₹6,50,000 × 7.1% ÷ 12 = ₹3,846
This notional interest accumulates across 12 months and is credited as a lump sum on March 31. The compounding effect over 15 years turns a consistent ₹1.5 lakh/year contribution into a corpus of roughly ₹40–42 lakh at 7.1% — use the PPF calculator on this page to model your exact scenario.
Partial Withdrawal Rules
You cannot touch PPF money freely during the lock-in, but partial withdrawals are permitted from year 7 onward (i.e., from the financial year following the completion of 6 years).
The maximum you can withdraw in any year is the lower of:
- 50% of the balance at the end of the 4th year preceding the withdrawal year, or
- 50% of the balance at the end of the immediately preceding year
Only one partial withdrawal is allowed per financial year, and it is completely tax-free. You do not need to repay it — it reduces your corpus permanently.
Example: Your balance at end of FY2020 (4 years before FY2024 withdrawal) was ₹8,00,000 and at end of FY2023 was ₹14,00,000. The withdrawal limit is 50% of ₹8,00,000 = ₹4,00,000.
Loan Against PPF
Between years 3 and 6 of the account (when partial withdrawal isn't yet available), you can take a loan against your PPF balance. Loans are not available after year 6, once partial withdrawals become eligible.
- Maximum loan amount: 25% of the balance at the end of the 2nd year preceding the loan application year.
- Repayment period: 36 months. If not repaid within 36 months, the interest rate jumps from 1% above PPF rate to 6% above PPF rate — a steep penalty.
- A second loan is only possible after the first is fully repaid.
The loan facility is useful for short-term liquidity needs in the early years, but the math rarely favors it over alternatives like a personal loan from a competitive lender, especially given the repayment window constraints.
Extension Blocks: What Happens After 15 Years
At maturity, you have three choices. The decision must be made before the maturity date — there is no grace period to decide afterward while keeping the account active under the same terms.
| Option | How to activate | Deposit allowed? | Withdrawal rule |
|---|---|---|---|
| Close and withdraw | Submit closure form | No | Full corpus, tax-free |
| Extend without contribution | Do nothing (automatic) | No | One withdrawal per year, any amount |
| Extend with contribution (5-year blocks) | Submit Form H within 1 year of maturity | Yes, up to ₹1.5L/year | One withdrawal per year, up to 60% of balance at block start |
The extension with contribution is the most powerful option for anyone who doesn't need the money immediately. You continue earning tax-free interest, get 80C deductions on fresh contributions, and the 5-year block can be renewed indefinitely. Many investors effectively use PPF as a perpetual tax-free savings vehicle well into their 60s and 70s.
If you miss the Form H deadline, the account is automatically treated as extended without contribution — you lose the ability to make fresh deposits and the 80C benefit for that block. This is one of the most common and costly administrative mistakes PPF account holders make.

常见问题
Can I open more than one PPF account?+
No. Each individual can hold only one PPF account in their own name. You may additionally hold one account as a guardian for a minor child, but deposits across both accounts combined cannot exceed ₹1.5 lakh per year. A second personal account opened in error earns no interest and the principal is refunded without interest.
Is PPF interest rate fixed for the full 15 years?+
No. The PPF interest rate is set by the government each quarter and can change. Your account earns whatever rate is declared for each quarter — it is not locked in at the rate prevailing when you open the account. Historically the rate has ranged from about 7% to 12% over the decades.
What happens to a PPF account when the account holder dies?+
The nominee or legal heir can claim the balance, and the account is closed. The corpus is paid out tax-free. The account cannot be continued by the nominee — PPF accounts are non-transferable and cannot be inherited as active accounts.
Does depositing in lump sum vs. monthly installments affect returns?+
Yes, significantly. Since interest is calculated on the minimum balance between the 1st and 5th of each month, depositing the full ₹1.5 lakh at the start of April (before the 5th) earns interest for all 12 months. Monthly installments earn progressively less interest. The lump-sum strategy at year-start is consistently more efficient.
Can PPF be used as collateral for a home loan?+
PPF balances can be pledged as security for loans only through the specific PPF loan facility (available in years 3–6). They cannot be pledged as collateral for external loans like home loans or personal loans from banks — this is a legal restriction, not a bank policy.
