The fundamentals
Section 80C allows a deduction of up to ₹1,50,000 from gross total income, available only under the old regime.
Multiple instruments qualify, with very different risk/return profiles — from guaranteed government schemes (PPF, EPF) through tax-saver mutual funds (ELSS) to insurance premiums and home-loan principal repayments.
The deduction is the SAME (30 paise per rupee at 30% marginal rate, less at lower brackets). What varies is the POST-TAX RETURN ON THE INVESTED ₹1.5L over time, plus the lock-in period.
The eight 80C instruments — ranked by post-tax return
FY 2025-26 · sorted best to worst on post-tax CAGR for a 30%-bracket investor
| Instrument | Lock-in | Stated return | Post-tax notes |
|---|---|---|---|
| ELSS (equity tax-saver MF) | 3 yrs (per SIP) | 11–13% historical | LTCG > ₹1.25L/yr @ 12.5% |
| Sukanya Samriddhi (SSY) | 21 yrs | 8.2% | EEE — girl child only, ₹1.5L cap/girl |
| EPF (incl. VPF) | Retirement / 5 yrs | 8.25% | Tax-free if 5+ yrs continuous |
| NSC (5-yr) | 5 yrs | 7.7% | Interest reinvested counts to next year's 80C |
| PPF | 15 yrs | 7.1% | EEE (full tax-free) |
| Tax-saving FD (5-yr) | 5 yrs | 7.0–7.5% | Interest taxable yearly → ~4.9% post-tax |
| Home loan principal | Loan tenure | n/a (debt repayment) | Fills 80C with no fresh outlay |
| LIC / endowment / ULIP | Policy term | 4–6% (incl. mortality) | Cap on premium-to-sum-assured ratio |
All instruments share the ₹1.5L combined 80C cap per FY. Old regime only — under the new regime, none of these earn deduction (but the underlying investment still grows). ELSS dominates on 10+ year horizons; SSY beats PPF by ~1pp if you have a daughter.
Why ELSS dominates (in plain words)
₹1.5L/year into ELSS at 12% CAGR over 15 years compounds to ~₹62L corpus. Same ₹1.5L into PPF at 7.1% compounds to ~₹41L. The ELSS gap is ~₹15-18L after LTCG — and ELSS only locks each SIP for 3 years vs PPF's 15. Trade-off: equity volatility.
Why tax-saving FD is the wrong default
Banks push 5-yr tax-saving FDs because they're profitable. The advertised 7% is taxable EVERY year at slab rate → ~4.9% effective for 30%-bracket savers. PPF at 7.1% tax-free wins by 2.2 percentage points. Never default to tax-saving FD.
Worked example
Compare ₹1.5L deployed each year for 15 years in PPF vs ELSS vs 5-yr tax-saver FD, all old regime, 30% bracket.
PPF — 7.1% guaranteed
₹1.5L/year × 15 years compounded at 7.1% = ~₹41L corpus. EEE. Total tax saved during contributions: 30% × ₹22.5L = ₹6.75L. Total wealth gained: ₹41L corpus + ₹6.75L tax save − ₹22.5L contributed = ₹25.25L net.
ELSS — ~12% historical
Same ₹1.5L/year × 15 years at 12% = ~₹62L corpus. After LTCG tax (12.5% on gains above ₹1.25L/yr exemption) net post-tax wealth roughly ₹55–58L. Plus the same ₹6.75L tax save on the way in. Total wealth gained roughly ₹40-43L net.
ELSS beats PPF by ~₹15-18L over 15 years for the same ₹1.5L annual outlay, in exchange for accepting equity volatility. The tax-saver FD trails both substantially because interest is taxed every year at slab rate.

Important caveats
80C is a TOTAL ₹1.5L cap across ALL instruments. EPF + PPF + ELSS + insurance premiums + home-loan principal all share the same ceiling. Compute your total before adding fresh investments.
ULIPs and endowment policies have HIGH commission structures (15-30% of first-year premium). The post-tax CAGR rarely beats PPF; never beats ELSS over 10+ years.
Tax-saver FD interest is taxable every year. The advertised 7% rate is roughly 4.9% post-tax for 30%-bracket taxpayers — WORSE than PPF.
Premature withdrawal of NSC, ELSS, or tax-saver FD before lock-in triggers reversal of the deduction (added back to income in the withdrawal year).
80C is OLD-REGIME ONLY. Under the new regime, none of these deductions apply (though the underlying investments still earn their normal returns).
Common questions
I already pay enough EPF to fill 80C. Should I invest extra in PPF?
Generally no — your 80C is already maxed via EPF, so PPF won't get you additional deduction. Invest the marginal money in equity index funds (no 80C, but long-term wealth-building) or NPS for the additional ₹50K 80CCD(1B). Only invest in PPF if you'd otherwise hold the money in low-return savings.
What about Section 80CCD(1B) — is that separate from 80C?
Yes — 80CCD(1B) gives an ADDITIONAL ₹50,000 deduction for NPS, OVER AND ABOVE the 80C ₹1.5L cap. So a salaried employee with EPF maxing 80C should also be putting ₹50K into NPS Tier-I to unlock another ₹15K of tax savings at 30% bracket.
Does the home loan principal really fill 80C automatically?
Yes — request the annual loan provisional statement from your bank in February. The principal-paid line is your 80C contribution. Most ₹50L+ home-loan EMIs put ₹50K-1L of principal toward 80C in the first few years, rising thereafter.
ELSS lock-in is 3 years per investment — but I do SIPs. When does each SIP unlock?
Each SIP installment has its OWN 3-year lock-in from the date of that installment. So a monthly SIP started Jan 2025 will have its January 2025 contribution unlock in Jan 2028, February's in Feb 2028, etc. Plan redemptions carefully if you have multiple SIPs.
I'm in the new regime. Is 80C completely useless?
For tax purposes yes — the deduction doesn't apply. But the underlying investments still serve their original purpose (long-term wealth, retirement, child education). Don't STOP investing; just stop choosing instruments BECAUSE of 80C. ELSS still beats PPF on returns even without the deduction.
When this doesn’t apply
- • You're on the new regime — 80C doesn't apply, so optimise for investment returns directly, not the deduction.
- • Your EPF + home-loan principal already exceed ₹1.5L — additional 80C investment yields zero tax benefit. Direct the marginal money to NPS (₹50K under 80CCD(1B)) or index funds.
- • You're approaching retirement and need liquidity — 80C instruments lock-in for 3-15 years. Don't trap your last 5-year corpus in a 15-year PPF.
