Before anything else, one qualifier that changes this entire article for many readers: Section 80C is only available under the old tax regime. If you have opted for the new regime — now the default — you cannot claim it at all. Work out which regime suits you first; deductions come second.
For those staying in the old regime, 80C allows a deduction of up to ₹1.5 lakh from taxable income. At the 30% slab plus 4% cess, that is a saving of ₹46,800 a year. At 20%, it is ₹31,200.
What already counts, before you invest anything
This is where most people lose money — by investing fresh into 80C without checking how much is already used up:
- Your EPF contribution — 12% of basic salary, deducted every month. On a ₹10 lakh basic, that is ₹1.2 lakh gone from your ₹1.5 lakh limit.
- Life insurance premiums you already pay
- Home loan principal repayment (the interest goes under Section 24(b), separately)
- Children's school or college tuition fees, for up to two children
- Stamp duty and registration paid on a house, in the year of purchase
Add these up first. Many salaried professionals with a home loan and school fees discover their ₹1.5 lakh is already exhausted, and every additional "tax-saving" policy they were sold delivers zero tax benefit.
The instruments, compared honestly
| Instrument | Lock-in | Typical return | Returns taxed? |
|---|---|---|---|
| ELSS mutual fund | 3 years | Market-linked | LTCG 12.5% above ₹1.25L/yr |
| PPF | 15 years | ~7.1% | Fully exempt |
| EPF | Till retirement | ~8.25% | Exempt within limits |
| NPS (80CCD) | Till 60 | Market-linked | Partly taxable at exit |
| Tax-saver FD | 5 years | ~6.5-7% | Fully taxable at slab |
| Sukanya Samriddhi | Till daughter is 21 | ~8.2% | Fully exempt |
| ULIP | 5 years | Varies, often 4-7% net | Conditionally exempt |
Two entries deserve comment. Tax-saver FDs are the weakest option on this list — a five-year lock-in for a return that is fully taxable at your slab, which after tax often fails to beat inflation. ULIPs bundle insurance and investment, and the charges in the early years are heavy enough that most buyers would do better with term insurance plus an ELSS fund.
The extra ₹50,000 nearly everyone misses
Section 80CCD(1B) allows an additional ₹50,000 deduction for NPS contributions, over and above the ₹1.5 lakh 80C limit. At the 30% slab this is another ₹15,600 saved.
The trade-off is real: NPS locks money until 60, and at maturity 40% must be used to buy an annuity whose income is taxable at slab rate. Worth taking if you are in the 30% bracket and already comfortable with retirement illiquidity — less compelling at lower slabs.
Salaried employees have one more route: under Section 80CCD(2), your employer's NPS contribution (up to 10% of basic and DA, or 14% for government employees) is deductible without touching either limit. This one is available in the new tax regime too.
Allocations that make sense
Aged 25-35, comfortable with market risk: ELSS ₹1,00,000 · PPF ₹50,000 · NPS ₹50,000 under 80CCD(1B). The three-year ELSS lock-in is the shortest of any 80C option, and over a long horizon equity has historically outpaced fixed-income alternatives.
Aged 35-50 with a home loan: Home loan principal typically absorbs ₹80,000-1,00,000. Add EPF and school fees and you may already be at the cap. Check before investing more, then use NPS for the extra ₹50,000.
Aged 50+, prioritising capital safety: PPF ₹1,00,000 · ELSS ₹50,000 to retain some growth · NPS ₹50,000.
With a daughter under 10: Sukanya Samriddhi deserves serious consideration — around 8.2%, entirely tax-free, and among the best sovereign-backed rates available.
Mistakes that cost real money
- Investing in March. A ₹12,500 monthly SIP into ELSS from April beats a ₹1.5 lakh scramble in March — you average your entry price instead of buying one day's NAV under deadline pressure.
- Buying an endowment policy for tax saving. A 20-year commitment returning 4-5% to save ₹46,800 once is a poor trade. The lock-in outlasts the benefit by two decades.
- Forgetting each ELSS instalment locks separately. In a SIP, every monthly instalment has its own three-year lock-in. The April 2026 instalment frees up in April 2029, the May one in May 2029.
- Overshooting ₹1.5 lakh. There is no benefit beyond the cap. Money above it should go into liquid, unlocked investments.
- Staying in the old regime out of habit. Run both calculations. With the standard deduction now ₹75,000 under the new regime, taxpayers without a home loan or large HRA claim are often better off there — in which case this entire article does not apply to you.
Which regime, in one paragraph
The old regime tends to win when your deductions are large — home loan interest, substantial HRA, full 80C, health insurance under 80D. The new regime tends to win when they are not. There is no universal answer; there is only your number. Compute both before the financial year starts, not in March.
