PPF: Why a Deposit on the 6th Earns Nothing That Month

Almost everything written about the Public Provident Fund talks about 31 March. That date matters, but it is the least interesting deadline in the scheme.

The rules are worth reading once, because they are unusually literal. The Public Provident Fund Scheme, 2019 is a gazette notification: what it says is what happens, automatically, without a letter, and in some cases permanently.

Why does the 5th of the month matter?

Because interest for a whole month is calculated on the balance as it stood on the 5th: interest "shall be eligible for a calendar month on the lowest balance at the credit of an account between the close of the fifth day and the end of the month."

Note the word lowest. Money arriving on the 6th is not in the account at the start of that window, so it earns nothing that month.

So: deposit on or before the 5th, or wait — the 6th and the 25th are worth the same. Paying in monthly on the 6th for fifteen years loses a month's interest fifteen times over, not to a penalty, just to the shape of the sentence. If you deposit once a year, the best date available is on or before 5 April.

What is the minimum, and what happens if you miss it?

₹500 in a financial year — and the Scheme defines "year" to mean "the financial year", so the line is 31 March, not 31 December. The limits: "A deposit which shall not be less than five hundred rupees and not more than one lakh fifty thousand rupees in multiple of fifty rupees may be made in an account in a year."

Miss it and no warning arrives. The account changes status: "Any account in which the account holder, having deposited five hundred rupees in the initial year, fails to deposit the minimum amount in the following years, shall be treated as discontinued."

Shall be treated as. No notice, no grace period, no discretion.

What does a discontinued account actually cost?

The fee is trivial and the consequences are not — the reverse of what most summaries imply.

Reviving it is cheap: "on payment of a fee of fifty rupees along with arrears of minimum deposit of five hundred rupees for each year of default." The ₹500 arrears are explicitly per defaulted year; confirm the exact arithmetic with your accounts office.

The real price is the next paragraph, and it is the part nobody mentions. While an account is discontinued, "the facility of loan and partial withdrawal shall not be allowed in such an account and the account holder shall be prohibited from opening another account in his name under this Scheme till final closure of such account."

A skipped ₹500 does not pause your account. It locks the money — no loan, no partial withdrawal — and bars you from opening a fresh PPF account until the old one is closed. Someone who let an account lapse in 2019 and decides in 2026 to "just start a new one" cannot.

And arrears count against your annual ceiling: the year's total "shall be inclusive of deposits made in respect of years of default of the preceding years but excluding the default fee."

The deadline you only get once

First, your maturity date is probably not what you think. It is fifteen years from the end of the year in which the account was opened — so an account opened in January 2026 runs its clock from 31 March 2026.

At maturity you have three options: close it, keep it without further deposits, or extend in a five-year block and keep contributing. The third has a hard window — the option "shall be made by the account holder before expiry of one year from the maturity of the account."

Miss that year and the door locks. "No deposits can be made in the account, if the account holder fails to give his option to continue the account within one year from the date of maturity. Any deposit made in such account shall be treated as irregular and refunded by the accounts office immediately without any interest."

The choice is one-way even if you do nothing wrong: "Once the account is continued without deposits for more than a year, the account holder shall not have the option again to continue the account with deposits."

A twelve-month window arriving fifteen or more years out, about a scheme you have stopped thinking about. Nobody remembers that unprompted.

Which reminders are worth setting?

Four, and the first two cover most of the risk:

• 1 April, every year. Deposit for the new financial year in the first week. This one reminder gets the best interest treatment and clears the ₹500 minimum on day one, so the discontinuation rule can never touch you.
• 20 March, every year. A backstop, catching the year before it closes if 1 April went unanswered.
• The 3rd of the month, if you deposit monthly. Two days of margin before the 5th.
• Your maturity year, and again nine months later, for the extension election. Work the date out now — fifteen years from the end of the financial year you opened in — because nothing will remind you.

In ReminderIt you can set these by message — "remind me every year on 1 April to deposit in my PPF" — and it reads the schedule back before saving. The first three suit annual recurring reminders; the maturity one is better as a one-off with the real date in it.

Before you rely on any of this

Do not take an interest rate from any article, including this one. The Scheme's text carries a figure from when it was notified in December 2019, and small savings rates are revised quarterly by the Ministry of Finance. The current rate is a thing to look up, not to remember.

This describes published rules, not financial advice. Whether PPF suits you, and what it does to your tax position, are questions for a qualified adviser. Your accounts office — the post office or bank holding the account — is the authority on your account's dates and balances.

The shape, though, is plain: interest that rewards the first five days of the month, a ₹500 floor that silently disables the account, and a twelve-month window fifteen years out that you cannot reopen. None of them send you a letter.
