PPF, ELSS and NPS — three tax savers that are not substitutes
They share a deduction section and almost nothing else. Lock-in, liquidity, taxation at exit and who they suit differ completely.
Every February these three get compared on one axis — returns — as though they were competing products. They are structurally different instruments that happen to share a deduction, and the differences that matter are elsewhere.
The comparison that is usually made
| PPF | ELSS | NPS | |
|---|---|---|---|
| Return | Fixed, government-set | Market-linked equity | Market-linked, mixed |
| Lock-in | 15 years | 3 years | Until retirement |
| Risk | None | High | Moderate to high |
That table makes ELSS look obviously superior — highest expected return, shortest lock-in. The table is incomplete.
The comparison that matters
PPF is a debt instrument with an unusual tax status. Contribution deductible, interest exempt, maturity exempt. A guaranteed, tax-free return of that quality is not available anywhere else, and comparing it to equity misses the point: it is the safe part of a portfolio, not a competitor to the risky part. Judge it against a fixed deposit, where it wins decisively after tax.
ELSS is equity with the shortest lock-in of any tax-saving option. Three years is short enough to be almost irrelevant for money that should be in equity for a decade anyway. Gains at exit are taxed as long-term capital gains.
NPS is a retirement account, and the lock-in is the product. You cannot access it before retirement except in narrow circumstances, and at exit a portion must be annuitised. It carries an additional deduction beyond the main limit, which is a genuine advantage — but the annuity requirement and the taxation of annuity income are the terms of the deal, not a footnote.
The 15-year PPF detail worth knowing
Interest is calculated on the lowest balance between the 5th and the last day of each month. Depositing on the 4th earns a full month's interest; depositing on the 6th earns nothing for that month. Across 15 years that timing alone is worth a meaningful sum for no effort.
The account can also be extended in five-year blocks after maturity, with or without further contributions — and the extended account keeps its tax-free status.

How to choose
Ask what the money is for before asking what it returns.
- Retirement money you genuinely will not touch, in a high tax bracket → NPS deserves a look.
- Long-horizon growth, comfortable with volatility → ELSS.
- The safe, fixed portion of a portfolio, in a high bracket → PPF beats a taxed deposit.
- Money needed within five years → none of these. The lock-ins make them unsuitable regardless of the deduction.
That last case is the one that goes wrong most often, because the deduction is claimed in one year and the liquidity problem appears in another.
Where these figures come from
- Income Tax Department, Government of India — Slabs, deductions, exemption limits and holding periods
- National Savings Institute, Ministry of Finance — Small savings rates — PPF, SSY, NSC, post office schemes
