What is Section 80C?
Section 80C lets you subtract up to ₹1.5 lakh a year from your taxable income, in exchange for putting that money into one of a fixed list of instruments. It is the largest single deduction available to most salaried taxpayers.
It exists only under the old tax regime. On the new regime there is no 80C at all, so none of what follows applies to you.
How much tax does 80C actually save?
The deduction is worth your marginal rate, not a fixed amount:
| Your old-regime slab | Tax saved on the full ₹1.5 lakh |
|---|---|
| 30% | ₹46,800 |
| 20% | ₹31,200 |
| 5% | ₹7,800 |
Figures include 4% cess. Below the taxable threshold the deduction saves nothing, because there was no tax to remove — which is worth knowing before locking money away for fifteen years to chase it.
What counts toward the 80C limit
The ₹1.5 lakh is a combined ceiling across everything below, not a limit per instrument:
- EPF employee contribution — already happening from your salary, and already counted.
- Home-loan principal repayment — the principal portion of your EMI, not the interest.
- ELSS equity mutual funds, 3-year lock-in.
- PPF, 15-year account.
- Sukanya Samriddhi, for a daughter under 10.
- Life insurance premiums, including term cover.
- 5-year tax-saving fixed deposits and the 5-year post office Time Deposit.
- NSC, and the interest it accrues in years 1 to 4.
- Children's tuition fees, up to two children, tuition only.
- Stamp duty and registration on a house purchase, in the year paid.
The first two matter most because they are usually already consuming the limit. Someone with an EPF deduction and a home loan may find the ₹1.5 lakh is full before they invest a rupee deliberately — in which case an additional ELSS or PPF contribution buys no further deduction.
Start by counting what already qualifies
Before adding anything, total up what is happening automatically: EPF from your payslip, home-loan principal from the amortisation schedule, tuition fees already paid, insurance premiums already due.
That number is often ₹80,000 to ₹1.2 lakh on its own. The genuine decision is only about the gap, and the gap is usually much smaller than the ₹1.5 lakh headline suggests.
Comparing the 80C options
They differ on three axes that matter more than the shared tax break: how long the money is locked, whether the return is guaranteed, and how the maturity is taxed.
| Instrument | Lock-in | Return | Tax on returns |
|---|---|---|---|
| EPF | Until retirement, with exceptions | 8.25% declared annually | Tax-free after 5 years of service |
| PPF | 15 years | 7.1%, reviewed quarterly | Tax-free |
| Sukanya Samriddhi | Until the girl is 21 | 8.2%, reviewed quarterly | Tax-free |
| ELSS | 3 years | Not guaranteed, equity-linked | 12.5% LTCG above ₹1.25 lakh |
| NSC | 5 years | 7.7%, fixed at purchase | Taxable at slab |
| 5-year tax-saving FD | 5 years | Set by the bank | Taxable at slab |
| Life insurance premium | Policy term | Depends entirely on policy type | Varies |
ELSS has the shortest lock-in on the list and the only return that can be negative. The guaranteed options trade that away for certainty and, in the case of PPF and SSY, a tax-free maturity. Which trade suits a particular rupee depends on when you need it back and whether a fall in the meantime would force you to sell.
Insurance premiums and 80C
Premiums qualify up to the ₹1.5 lakh limit, and pure term insurance qualifies alongside endowment and money-back policies.
The distinction worth understanding is what you are buying. Term insurance is protection: a large cover for a small premium, with nothing back if you survive the term. Endowment and money-back policies bundle protection with a savings product, which is why the premium is many times higher for the same cover, and why the effective return on the savings portion is typically well below what the same money earns in a dedicated instrument.
Both are 80C-eligible. The deduction does not distinguish between them, so it should not be the thing that decides between them either.
Beyond ₹1.5 lakh: NPS under 80CCD(1B)
An additional ₹50,000 deduction is available for NPS contributions, over and above the 80C ceiling. At the 30% slab that is a further ₹15,600 of tax saved.
The cost is liquidity. NPS locks until 60, and at maturity at least 40% of the corpus must buy an annuity, whose income is taxable at slab. The 60% you can withdraw is tax-free.
Separately, your employer's NPS contribution under 80CCD(2) is deductible up to 14% of basic — and unlike everything else here, that one also works in the new regime.
Can I invest more than ₹1.5 lakh in these instruments?
Yes. The ceiling is on the deduction, not the investment. PPF accepts up to ₹1.5 lakh a year regardless of what the deduction is doing, and ELSS has no cap at all.
What stops is the tax benefit. Money going into these beyond the limit should be judged purely on whether the instrument suits the goal, because from that point it is competing on merit with every non-80C option available.
