PPF Account Extension Rules 2026: How the 5-Year Block Extension Works — With or Without Contribution

By Nitish Bharadwaj · Published Aug 19, 2026 · 6 min

A matured PPF account can be extended indefinitely in blocks of 5 years, but only one of two ways: with contribution, which requires Form H within a year of maturity and keeps the 80C benefit alive, or without contribution, the automatic default that still earns interest but blocks further deposits. This guide covers the Form H deadline, why late deposits stop earning interest, the very different withdrawal caps each mode carries, and what happens to the account if the holder dies mid-block.

PPF's 15-year lock-in is often treated as the finish line, but for most account holders it isn't — the account simply rolls into another block instead of closing. That next block can run in one of two completely different modes, and which one you end up in depends on a single form and a one-year deadline that's easy to miss entirely.

The Two Extension Modes, at a Glance

Extension With Contribution: Form H Is the Whole Ballgame

If you want to keep depositing into PPF past the 15-year mark — and keep claiming it under Section 80C — you have to submit Form H at the post office or bank branch holding your account, within one year of the date your account matured. This isn't a formality; it's what makes every rupee you deposit after maturity valid and interest-bearing. Each further 5-year block needs its own Form H filed within a year of that block's own maturity, if you want to keep contributing beyond it.

Extension Without Contribution: What Happens by Default

File nothing within a year of maturity, and your account doesn't close — it automatically continues in extension-without-contribution mode. The existing balance keeps earning the prevailing PPF rate, currently 7.1% for the July-September 2026 quarter, exactly as it did before maturity. You can no longer deposit into the account in this mode, but you gain something the with-contribution mode doesn't offer: you can withdraw any amount, once a financial year, with no percentage cap, and you can close the account entirely at any point without needing to meet any of the specific grounds that apply to premature closure of an active account.

Why the Withdrawal Rules Are So Different Between the Two

The gap exists because the two modes serve different purposes. Extension with contribution treats your account as still actively growing — like a fresh 5-year PPF commitment — so it caps withdrawals the same way active PPF caps partial withdrawals, at 60% of the balance you started the block with, spread across one withdrawal a year for that block. Extension without contribution treats your balance as essentially matured money sitting in a high-interest holding pattern, so it gives you full access, one withdrawal at a time, without limiting how much of it you take.

Can You Switch Modes Once a Block Has Started?

No — whichever mode applies at the start of a 5-year block stays fixed for that entire block. If you're in without-contribution mode and later decide you want to resume depositing, you can't do it mid-block; you have to wait until that block's own maturity and file Form H at that point to start a fresh with-contribution block. The reverse also holds: someone in a with-contribution block who simply stops depositing doesn't automatically switch to the more flexible without-contribution withdrawal rules until the block ends.

How Many Times Can You Extend?

There's no cap on the number of 5-year blocks you can add. An account holder who matured their PPF at 15 years can keep extending in blocks of five for as long as they choose — filing or skipping Form H independently at the start of each new block based on whether they still want to contribute at that stage of their life.

What Happens If the Account Holder Dies During an Extension

A PPF account cannot be continued or extended in a deceased holder's name. On death, the nominee or legal heir receives the balance and the account is closed — there's no option for the heir to keep the account running for its remaining block or to file a fresh Form H themselves. If you're the nominee on someone else's extended PPF account, this is worth knowing before you assume the account itself carries forward.

• Still want to keep building this corpus under 80C? File Form H within a year of maturity and stay in with-contribution mode.
• Done contributing but want the balance to keep compounding with full withdrawal flexibility? Do nothing — without-contribution mode kicks in automatically.
• Already deposited after maturity without filing Form H? Stop depositing now and get Form H filed before the next block, so future deposits aren't treated as irregular.

If you're deciding whether to extend or simply close out and redeploy the money, our PPF withdrawal, loan, and premature closure guide covers every way to access PPF money before this stage, and our PPF calculator can model how an extended block compares against starting a fresh contribution elsewhere. Timing your deposits inside an extended account matters just as much as it did before maturity — our PPF interest calculation guide covers the 5th-of-the-month rule that decides whether a given month's deposit earns interest at all. And if you're an NRI whose PPF account is approaching this stage, extension isn't available to you in the same way — our PPF for NRIs guide explains why residency status changes the rules entirely.
