Section 80C: The Complete Tax-Saving Guide for 2026
Section 80C is the most-used tax break in India — up to ₹1.5 lakh off your taxable income. Here's what qualifies and how to use it well.
Section 80C of the Income Tax Act lets you reduce your taxable income by up to ₹1.5 lakh a year by investing in or spending on certain approved instruments. It's the single most popular tax deduction in India — but it only works under the old tax regime, so the first decision is which regime you're on.
First, does 80C even apply to you?
80C deductions are available only in the old regime. If you're on the new regime, you can't claim them — so before optimising 80C, confirm the old regime is actually cheaper for you using the new vs old tax regime calculator. If the old regime wins (often the case when you also claim HRA and home-loan interest), then maximising 80C is worth it.
What qualifies under 80C
The ₹1.5 lakh limit is a combined cap across all of these:
- ELSS mutual funds — equity funds with a 3-year lock-in; the only 80C option with real equity growth potential.
- PPF — Public Provident Fund, 15-year, government-backed, tax-free returns.
- EPF — your own provident fund contribution from salary already counts.
- Life insurance premiums — for term or traditional policies.
- 5-year tax-saving FDs and NSC.
- Principal repayment on your home loan, and children's tuition fees.
- Sukanya Samriddhi for a girl child.
How to choose between them
Since your EPF and home-loan principal may already fill part of the ₹1.5 lakh, first add those up — you might need less fresh investment than you think. For the remaining gap, ELSS suits long horizons and higher returns, while PPF suits safety and guaranteed tax-free growth. Many people split across both.
Beyond 80C
Don't stop at 80C — the old regime has more: 80D for health insurance, 80CCD(1B) for an extra ₹50,000 via NPS, and Section 24(b) for home-loan interest. Stacked together, these can push the old regime well ahead of the new one — which is exactly why you should re-run the regime comparison after totalling all your deductions.
The bottom line
80C can save you up to ₹46,800 in tax (at the 30% slab) — but only in the old regime, and only if you actually invest before 31 March. Check your regime first, count what you're already contributing, and fill the rest with instruments that match your goals.
