Public Provident Fund (PPF) — Complete Guide to Interest, Tax Benefits, Withdrawals & Rules

If you have ever asked a parent, an HR colleague or a senior chartered accountant for a "safe place to save tax", odds are the answer included PPF — the Public Provident Fund. Decade after decade, PPF has stayed at the top of every Indian saver's tax-planning list, and for very good reasons: a sovereign-backed return, a fully tax-free maturity corpus, and the discipline of a long lock-in that quietly builds wealth in the background.

This TaxFetch guide pulls together everything that matters about PPF in 2025 — the latest rule changes, the small timing trick that earns you a few thousand rupees more each year, withdrawal and loan mechanics, what happens if your account goes inactive, and how PPF stacks up against newer alternatives. Whether you are opening your first PPF account or trying to squeeze the last percentage of efficiency out of an existing one, you will find the answer below.

1. What exactly is PPF?

The Public Provident Fund is a long-term, government-backed savings scheme administered by India Post and most public and private sector banks. It was introduced in 1968 with a clear mandate — give ordinary Indians a safe, disciplined way to build a retirement corpus while enjoying meaningful tax breaks.

Three things make PPF stand out:

• Sovereign safety. Your money is effectively backed by the Government of India — there is no credit risk and no volatility.
• EEE tax status. Your contribution, the interest you earn each year, and the maturity proceeds are all tax-free. There aren't many investments left in the country that can claim this.
• Forced discipline. A 15-year lock-in is hard work, but it is precisely what turns a small annual deposit into a meaningful corpus by the time you actually need it.

The interest rate is reset by the Ministry of Finance every quarter to keep it in line with prevailing G-Sec yields. As of the latest quarterly review the rate stands at 7.1% per annum, compounded annually, and the maximum a single individual can put into a PPF account is ₹1.5 lakh per financial year.

2. Latest PPF rule changes — effective 1 October 2024

The Department of Economic Affairs notified three rule changes for PPF accounts that you should know about, especially if you opened an account for a child, hold more than one PPF account, or are an NRI.

2.1 Minor PPF accounts now earn savings-account interest

Earlier, an account opened in a minor's name continued to earn the full PPF rate. From 1 October 2024, a minor's PPF account earns interest only at the Post Office Savings Account (POSA) rate of 4% until the child turns 18. The 15-year maturity clock for such accounts now starts only on the day the minor becomes an adult.

2.2 Multiple PPF accounts in the same name

The rules have always said one PPF per individual, but enforcement was loose. Going forward, where a person holds more than one PPF account:

• Only the primary account earns the regular PPF interest, provided total contributions across all accounts do not exceed ₹1.5 lakh in a year.
• Balances from secondary accounts will be merged into the primary account up to the ₹1.5 lakh limit.
• Any remaining excess sitting in secondary accounts will be refunded without interest.

2.3 PPF for Non-Resident Indians (NRIs)

From 30 September 2024, NRIs no longer earn interest on PPF. Existing NRI account holders are allowed to continue their accounts till the original 15-year maturity but cannot extend them further. Older NRI accounts opened under the 1968 Scheme — where residency declaration in Form H was not enforced — earned the POSA rate up to 30 September 2024 and stop accruing interest entirely after that date.

3. PPF at a glance — the numbers you should remember

4. Who can open a PPF account?

• Any resident Indian individual can open one PPF account in their own name.
• A parent or legal guardian can open a PPF account on behalf of a minor, supported by valid age proof. The contribution from the minor's account still counts towards the guardian's combined ₹1.5 lakh limit.
• If a person opened a PPF account while they were a resident and later became an NRI, the account can run until original maturity but cannot be extended beyond 15 years.
• Hindu Undivided Families (HUFs) cannot open new PPF accounts. HUF accounts opened before 13 May 2005 may continue till maturity but cannot be extended.
• Trusts and other non-individual entities are not eligible.

5. Documents required

Whether you are walking into a branch or opening the account through net banking, you'll need the following:

• PPF Form A (account opening form) — available at any authorised bank branch or India Post.
• Identity proof — any one of Aadhaar, PAN, Driving Licence, Passport or Voter ID.
• Address proof — Aadhaar, latest electricity / telephone bill or ration card.
• Two recent passport-size photographs.
• Initial deposit cheque or pay-in-slip.
• For a minor's account, the child's birth certificate as age proof.

All copies must be self-attested, and you should keep originals handy for verification at the branch.

6. How to open a PPF account

6.1 Online — through your bank's net banking

1. Log in to your net banking or mobile banking app.
2. Look for "Open a PPF Account" under the Investments / Deposits section.
3. Choose Self Account for yourself, or Minor Account if it is for your child.
4. Confirm pre-filled KYC details and enter the proposed annual contribution.
5. Authorise with the OTP sent to your registered mobile number.
6. The account is opened instantly and the account number is emailed to you.

6.2 Offline — at a Post Office or bank branch

1. Pick up Form A from the nearest authorised branch (or download it from the bank's website).
2. Submit the completed form along with KYC documents and your photograph.
3. Make the initial deposit (₹500 minimum, ₹1.5 lakh maximum per FY).
4. Collect your passbook from the counter once the account is activated.

7. Key features of a PPF account

• 15-year lock-in with the option to extend in blocks of 5 years (with or without further contributions) up to 20, 25, 30 years and beyond.
• Sovereign-backed guaranteed returns — no market risk.
• Nomination facility — you can nominate one or more individuals to receive the proceeds in case of death.
• Flexible deposit modes — cash, cheque, demand draft, NEFT/RTGS, UPI auto-debit or net banking.
• Multiple deposits allowed in a year. Just make sure at least one deposit (₹500 minimum) goes in each financial year to keep the account active.
• Low minimum opening balance — start with as little as ₹100 to open the account, and ₹500 a year keeps it running.

8. Limitations you should be aware of

• Long lock-in. The 15-year horizon is great for retirement planning but unforgiving if you have short-term liquidity needs.
• Returns may barely beat inflation. 7.1% looks decent on paper, but India's average inflation has hovered around 5-6% for the last decade. PPF should sit alongside equity, not replace it.
• Hard ceiling of ₹1.5 lakh per year — there is no way to put in more than this amount, no matter how high your income is.
• Withdrawal restrictions kick in only from the 7th financial year and even then only one withdrawal is allowed per year.
• Eligibility is limited to resident Indian individuals. NRIs, HUFs and trusts are out.

9. Interest rate, calculation method & the 5th-of-the-month trick

The Government of India reviews PPF interest every quarter. The current rate is 7.1% per annum, compounded annually. Interest, however, is computed on a monthly basis on the minimum balance between the 5th and the last day of the month, and credited to the account at the end of the financial year (31 March).

This timing matters more than most people realise. Suppose you make a fresh ₹1.5 lakh deposit on 6 April. For that entire month, the "minimum balance between the 5th and 30th" is whatever the balance was before your deposit, because the higher post-deposit balance was not present on the 5th. Your fresh deposit therefore earns no interest for April. Push the same deposit to 4 April and you pocket roughly an extra ₹880 of interest just from one earlier credit — repeat that across years and the difference becomes meaningful.

10. Where you can open a PPF account

Most national and large private banks are authorised to open PPF accounts. Common options include:

• Public sector: State Bank of India, Punjab National Bank, Bank of Baroda, Canara Bank, Union Bank of India, Bank of India, Indian Bank, Central Bank of India, IDBI Bank.
• Private sector: ICICI Bank, HDFC Bank, Axis Bank, Kotak Mahindra Bank.
• India Post through any Post Office Savings Bank counter.

The account, the rules, the interest rate and the tax treatment are identical regardless of where you open it. Pick the institution where your salary or savings account already sits — that makes lump-sum credits painless via internet banking.

11. Loan against your PPF balance

Need a short-term loan but don't want to break your PPF? You can borrow against it between the 3rd and the 6th financial year from account opening:

• Maximum loan amount: 25% of the balance at the end of the second year preceding the year in which the loan is applied for.
• Interest: 1% above the prevailing PPF rate (so currently ~8.1%) — far cheaper than most personal loans.
• Repayment: Within 36 months of the loan date.
• You cannot take a fresh loan until the previous one is repaid in full.
• The loan facility is no longer available once you start partial withdrawals from the 7th year.

12. Partial withdrawals from PPF

From the 7th financial year onwards, you can make one partial withdrawal per year. The maximum withdrawable amount is the lower of:

• 50% of the balance at the end of the 4th financial year preceding the year of withdrawal, or
• 50% of the balance at the end of the immediately preceding financial year.

How to make a partial withdrawal

1. Submit Form C at your bank/post office along with your PPF passbook.
2. The withdrawal is normally credited to your linked savings account within a few working days.
3. You can also process the same request through net banking with most large banks.

Premature closure

The account can be fully closed before maturity (after completion of 5 years) for very specific reasons — life-threatening medical treatment of the account-holder or dependents, higher education of the account-holder or dependent children, or change in residency status to NRI. A 1% interest penalty is applied on the withdrawn corpus.

13. Inactive PPF accounts and how to revive them

If you fail to deposit at least the ₹500 minimum in any financial year, the account is marked inactive. Consequences include:

• You cannot apply for a loan against the account.
• You cannot make partial withdrawals.
• The account cannot be extended beyond the original 15-year maturity in inactive status.

Reviving an inactive PPF account

1. Submit a written request to the bank or post office where the account is held.
2. Pay the minimum ₹500 contribution for each financial year that was missed.
3. Pay a penalty of ₹50 per year of default.
4. Once revived, the account resumes earning interest as normal and all features are restored.

14. Attachment immunity — the underrated PPF benefit

This is one of the lesser-known but most powerful features of PPF. Under Section 9 of the Public Provident Fund Act, 1968, the balance in your PPF account cannot be attached by any court order in respect of any debt or liability incurred by you. Whether it is a personal loan default, a business creditor, or any other civil liability — your PPF balance is protected.

This makes PPF particularly attractive for self-employed professionals, business owners and anyone whose income carries the risk of disputes or claims. (Note: tax authorities can still attach PPF for unpaid tax dues — the immunity is from civil/commercial creditors only.)

15. Tax treatment: why PPF earns the EEE label

"EEE" stands for Exempt-Exempt-Exempt, and PPF is one of the very few investments in India that ticks all three boxes:

• E for contribution: Up to ₹1.5 lakh of your annual PPF deposit qualifies for deduction under Section 80C of the Income Tax Act (Old Regime only).
• E for accrual: The interest credited to your PPF account every year is fully exempt from tax.
• E for maturity: The entire maturity corpus — principal plus 15 years of compounded interest — is paid out tax-free.

16. Maturity, extension and the smart exit strategy

At the end of 15 financial years, you have three clear choices:

1. Withdraw the entire balance. The full corpus is tax-free in your hands and the account is closed.
2. Extend with fresh contributions, in 5-year blocks. Submit Form H within one year of maturity. You can keep contributing up to ₹1.5 lakh a year and continue claiming Section 80C benefit.
3. Extend without further contributions. Don't sign Form H — by default the account continues to earn interest on the existing balance, and you can make one withdrawal per year of any amount you like.

For most people, the third option is hugely attractive in retirement — you keep earning sovereign-backed, tax-free interest at the prevailing PPF rate while drawing down the corpus as needed.

17. PPF vs ELSS vs NPS vs Tax-Saver FD — quick comparison

The honest answer is that these instruments are not in competition — they are complementary. A balanced 80C plan typically combines PPF for stability, ELSS for growth, and NPS for the additional ₹50,000 deduction under Section 80CCD(1B).

18. Frequently asked questions

Is PPF better than the New Tax Regime?

Not always. PPF earns tax-free returns regardless of the regime you choose, but the upfront 80C deduction is available only under the Old Regime. If your overall mix of deductions (HRA, 80C, 80D, home loan interest etc.) is large, the Old Regime + PPF is usually a winner. If you have very few deductions, the New Regime may give a lower tax outgo even though you "lose" the 80C deduction. Run both numbers — TaxFetch's calculator does this in one click.

Can I open more than one PPF account?

No. The rules now clearly say one PPF account per individual. If you already hold more than one, only the primary account will earn interest, and the rest will be merged or refunded without interest.

What happens if I deposit more than ₹1.5 lakh in a year?

The excess amount earns no interest and is not eligible for the Section 80C deduction. The bank or post office will eventually refund it without interest.

Can I open a PPF account for my spouse and claim a separate ₹1.5 lakh?

Yes — your spouse can open a PPF account in their own name and contribute up to ₹1.5 lakh, but the deduction under Section 80C will be available to whoever actually contributes from their taxable income.

Can I transfer my PPF account between banks or to a post office?

Yes. Submit a transfer request at the existing branch and the account will be moved to the destination branch. Account number, tenure and balance all carry over — there is no impact on interest or maturity.

What happens to my PPF if I die before maturity?

The balance is paid out to your nominee(s) (or, if none, your legal heirs) along with all accrued interest up to the end of the preceding month. This payout is also fully tax-free.

Can I claim a Section 80C deduction for PPF contributions made in my child's account?

Yes — contributions from a parent or guardian to a minor child's PPF account count towards the parent's 80C limit, but the combined contribution across the parent's and the child's accounts cannot exceed ₹1.5 lakh in a single financial year.

Is the PPF interest rate fixed for the entire 15 years?

No. The rate is reviewed every quarter by the Government of India. Once a quarter is over, the interest credited for that quarter is locked in — but the rate that applies for future quarters can change.

19. The TaxFetch bottom line

PPF is not the highest-returning investment you can pick — but it is arguably the most reliable rupee-for-rupee tax shelter available to a salaried Indian today. A 15-year discipline, fully sovereign safety, EEE tax treatment and a 7%-plus guaranteed return make it the perfect foundation block of every long-term portfolio.

Our practical recipe for using PPF:

1. Open the account as early in your career as possible — the 15-year clock is your best friend.
2. Treat it as your "bond bucket" inside a wider portfolio that also includes equity (direct stocks or ELSS) and possibly NPS for the extra ₹50,000 deduction.
3. Always credit your contribution before the 5th of the month — ideally in one lump sum at the start of the financial year.
4. Never let the account go inactive — even ₹500 a year keeps it healthy.
5. At maturity, choose the "extend without contribution" route in retirement so your tax-free interest engine keeps running while you draw down the corpus.
