PPF Rules: Lock-in, Partial Withdrawal, and Loans

Published July 20, 2026 · Updated October 3, 2026 · 6 min read · By Ramanathan · Paired with the PPF Calculator

The Public Provident Fund is prized for one thing above all: safe, tax-free growth guaranteed by the Government of India. But three rules come with it: a long lock-in, restricted withdrawals, and a specific loan window. They trip up a lot of savers, especially anyone who assumes they can dip into the account whenever they like. Here is how the money is actually locked, and the legitimate ways to reach it early. You can project the balance itself on the PPF calculator.

PPF rules at a glance

How long is the PPF lock-in period?

A PPF account runs for 15 financial years, and that term is the headline rule everyone knows. What surprises people is how the clock is counted: the 15 years are measured from the end of the financial year in which you opened the account, not the date you opened it. Open an account in the middle of a financial year and, in practice, your money is committed for a little over 15 years before full withdrawal is allowed. Within that window the account is genuinely locked — but "locked" does not mean completely untouchable, and two escape hatches exist for real needs.

Can you take a loan against your PPF account?

Between the third and sixth financial years, before partial withdrawals open up, you can take a loan against your PPF balance. You can borrow up to 25% of the balance at the end of the second year preceding the loan, and the loan carries a small interest rate above the PPF rate itself. It has to be repaid within 36 months, and until you clear it you cannot take a second loan. This facility exists precisely to bridge a short-term need in the early years without breaking the account — the balance keeps earning PPF interest on the untouched portion throughout.

When can you make a partial withdrawal from PPF?

From the start of the seventh financial year, the account switches from loans to partial withdrawals. Once a year you may withdraw up to the lower of 50% of the balance at the end of the fourth year preceding the withdrawal, or 50% of the balance at the end of the immediately preceding year. The withdrawal is tax-free, like everything else in PPF, and you do not have to repay it. This is the mechanism most people use when they genuinely need a slice of the corpus — a child's education, say — without sacrificing the account's tax status or its continued growth.

What happens at maturity

When the initial 15 years end you have three clear choices. You can withdraw the entire balance, completely tax-free, and close the account. You can extend in blocks of five years and keep contributing, which suits anyone who wants to keep the tax-free compounding running. Or you can extend without further contributions, leaving the existing balance to keep earning interest while you make no new deposits. This is useful if you have hit your savings target but like the guaranteed, tax-free return. The extension decision has to be made within a year of maturity, so it pays to plan it rather than let it default.

The premature closure exception

Full closure before 15 years is allowed only in narrow circumstances: serious illness of the account holder or a dependent, higher education of the account holder, or a change in residency status. Even then it is permitted only after the account has completed five years. It also comes with a penalty: the interest rate is reduced by 1% for the whole period the account has run. For almost everyone, the loan and partial-withdrawal routes are the sensible way to access money early. Premature closure is a last resort, not a planning tool.

The tax rule that makes it all worthwhile

PPF's rules feel restrictive because the reward on the other side is unusually generous. The account has EEE status: your contributions are deductible under Section 80C, the interest is exempt every year, and the maturity amount is exempt too. Only the contribution deduction depends on your regime — it applies under the old tax regime only, since the new regime, now the default, does not offer Section 80C. The tax-free interest and maturity hold either way, so PPF stays worthwhile even on the new regime, just without the upfront deduction. (The Income-tax Act, 2025 is renumbering Section 80C over the next couple of filing cycles, so confirm the current section number on the Income Tax Department's site when you file.) Very little else in India offers this combination. That is the trade the lock-in buys you — accept that the money is committed for the long term, and the government hands you a guaranteed return with no tax leakage at any stage. For a long-horizon, risk-free portion of a portfolio, that trade is hard to beat.

In stages:

How much will 15 years actually build?

At the current PPF rate of 7.1%, investing the full annual ceiling of ₹1,50,000 every year for the full 15-year term builds a maturity value of about ₹40,68,209. That is ₹22,50,000 of your own contributions plus roughly ₹18,18,209 in interest, all of it tax-free under EEE. That is also the ceiling case: investing less each year scales the maturity down proportionally. Run your own annual amount and rate on the PPF calculator to see the year-by-year growth.

Smaller deposits scale the result down in proportion. Here is the same 15-year term at three yearly amounts, at 7.1%:

What the loan and withdrawal rules are worth in rupees

The 25%-of-balance and 50%-of-balance rules above are easy to read and hard to picture. Here is what they actually come to for an account contributing the full ₹1,50,000 ceiling every year at 7.1% — the same account whose ₹40,68,209 maturity value is above.

The pattern worth noticing: the loan facility in the early years is modest — worth borrowing for a genuine short-term gap, not a substitute for an emergency fund. The withdrawal facility from year 7 onward grows into a meaningful sum instead, because it is pegged to a much larger, more mature balance. That is exactly why the two escape hatches exist in that order: small, cheap access early, then larger, no-repayment access once the account has had time to compound.

Planning around the rules

The practical takeaway is to treat PPF as genuinely long-term money and size your contributions accordingly. Keep an emergency fund elsewhere, in something liquid, so you never have to lean on the loan or withdrawal provisions for a routine cash crunch. Use the ₹1,50,000 annual ceiling if you can, since the tax-free compounding is most valuable at the maximum, and start early — the last few years of the term contribute the most because of compounding. Model different contribution levels and terms on the calculator, then leave the account alone to do its job.
