PPF: the only fully tax-free guaranteed-return instrument
Public Provident Fund is a 15-year government savings scheme with EEE (Exempt-Exempt-Exempt) tax status — your contribution, the interest earned, and the maturity amount are all tax-free. No other guaranteed-return product on this list matches that. The tradeoff is liquidity: your money is largely locked in for 15 years, with limited partial-withdrawal and loan-against-balance options along the way.
PPF vs other Section 80C instruments
| Instrument | Rate | Lock-in | Interest tax treatment |
|---|---|---|---|
| PPF | 7.1% (fixed, reviewed quarterly) | 15 years | Tax-free (EEE) |
| NSC | 7.7% | 5 years | Taxable (but reinvested interest counts toward 80C in year 1-4) |
| SCSS (60+) | 8.2% | 5 years | Taxable |
| ELSS mutual fund | Market-linked | 3 years | 12.5% LTCG above ₹1.25L |
| 5-year tax-saving FD | ~6.5-7.5% | 5 years | Taxable |
PPF has the lowest rate among guaranteed options here but the best tax treatment and the longest track record of government backing — it's best suited as the "safe floor" of a long-term portfolio, not the whole plan.
Partial withdrawal and loan against PPF
Two separate, often-confused features:
- Partial withdrawal — available from the 7th financial year, once per year, capped at 50% of the balance at the end of the 4th preceding year or the immediately preceding year (whichever is lower)
- Loan against PPF — available between the 3rd and 6th year, up to 25% of the balance at the end of the 2nd preceding year, at a modest interest rate — useful as a low-cost short-term loan without breaking the account
What happens at 15-year maturity
Three options: withdraw the full tax-free amount, extend for a 5-year block with further contributions (submit Form H within 1 year of maturity), or extend without further contributions (balance keeps earning interest, one withdrawal per year permitted). If you're unsure, extension without contribution keeps your options open with the least commitment.
