Section 80C: What Is Already Filling Your ₹1.5 Lakh Before You Invest a Rupee

Every March, salaried Indians buy tax-saving products they do not need, because nobody told them the limit was already full.

Step one: check what is already in there

Section 80C is a ₹1,50,000 total, not ₹1,50,000 per product. These all draw on the same pool:

Already counting, probably	Typical amount
Your EPF contribution (12% of basic)	₹50,000–₹1,20,000
Home loan principal repayment	₹50,000–₹1,50,000
Children's school and college tuition fees (two children)	varies, often substantial
Life insurance premiums you already pay	varies
Sukanya Samriddhi deposits	varies

A salaried person with a home loan and two children in school frequently finds 80C is full before investing anything new. Someone earning ₹15 lakh with basic at 40% contributes ₹72,000 to EPF automatically — nearly half the limit, without lifting a finger.

Do this arithmetic in April, not March. Your payslip shows the EPF figure and your lender's provisional certificate shows the principal split.

Step two: if there is room, compare properly

Option	Lock-in	Returns	Risk
PPF	15 years	~7.1%, reset quarterly	None — sovereign
ELSS	3 years	Market-linked	Full equity risk
NPS Tier I	Until 60	Market-linked	Market risk
5-year tax-saver FD	5 years	~6.5–7.5%	None, but fully taxable interest
Sukanya Samriddhi	Until daughter is 21	~8.2%	None — sovereign
ULIP	5 years	Market-linked	Market risk plus charges
Traditional insurance	Full term	~4–5% effective	Low, but poor value

ELSS has the shortest lock-in of any 80C option at three years, and the best long-run return potential. Its gains are taxed as equity capital gains at 12.5% above ₹1.25 lakh a year, unlike PPF which is entirely tax-free.

PPF cannot lose money. Over 15 years, ₹1.5 lakh a year at 7.1% builds ₹40.68 lakh, entirely tax-free. The same amount in ELSS at 12% builds ₹62.63 lakh, or about ₹57.77 lakh after tax — roughly ₹17 lakh more, with real variance attached.

Insurance-as-investment is where most 80C money goes and where it does worst. A traditional endowment policy returns roughly 4–5% effective while locking you in for the full term. Buy term insurance for protection — it is far cheaper for the same cover — and invest the difference separately.

Step three: the ₹50,000 nobody uses

Section 80CCD(1B) gives an additional ₹50,000 for NPS, on top of the ₹1.5 lakh 80C limit. It is the only way to claim more than ₹1.5 lakh in this space, and at the 30% slab it is worth ₹15,600 a year.

The catch is that NPS Tier I is locked until 60, and at 60 you must use 40% of the corpus to buy an annuity whose income is taxable. Worth it if you were going to save for retirement anyway; not worth it if you might need the money at 50.

The question that comes first

None of this applies under the new tax regime. No 80C, no 80CCD(1B), no 80D.

Before doing any 80C planning at all, check which regime suits you. At a ₹15,00,000 salary you would need ₹5,43,750 of total deductions before the old regime beats the new one — far more than most people have. If the new regime wins for you, the entire 80C exercise is irrelevant and you should choose investments on their merits alone.

That reframes ELSS in particular: there is no reason to accept a three-year lock-in when the deduction that justified it does not apply to you. A plain diversified equity fund does the same job with no lock-in.

Run the old vs new regime calculator first. Then, if the old regime wins, work out how much 80C room you actually have — and use the PPF calculator and SIP calculator to compare what to put in it.

The one deduction that survives the new regime

Section 80CCD(2) — your employer's NPS contribution, up to 14% of salary. It works under the new regime, where almost nothing else does.

If your employer offers NPS in the salary structure, routing part of your CTC through it is the single most valuable structuring move available to a new-regime salaried taxpayer. Most companies that offer it never mention it. Ask.
