Section 80C, Now Section 123: Save Up to ₹1.5 Lakh

Section 80C is the most famous section of the Income Tax Act, the one your office finance team emails about every January, the reason insurance agents suddenly remember your birthday in March. It lets you take up to ₹1.5 lakh off your taxable income. Under the Income-tax Act, 2025, in force since 1 April 2026, the same deduction with the same limit is section 123; this guide uses both names. There is also a catch that decides whether it matters to you at all, so start there.

The big caveat: old regime only

Section 80C is available only under the old tax regime. If you are in the new regime, which is the default and the better deal for most salaried people, section 123 gives you nothing. Zero. Your ELSS SIP and PPF deposits are still fine as investments, but they earn no tax deduction under the new regime.

This is the single most important thing to understand before locking money away "to save tax". If the new regime already makes your salary tax-free (up to ₹12.75 lakh thanks to the ₹75,000 standard deduction and the ₹60,000 rebate under section 156), an 80C investment saves you nothing extra. Run your numbers through the income tax calculator first, and see our new vs old regime comparison for the break-even logic.

Still on the old regime, because of a big home loan, hefty HRA, or legacy commitments? Then 80C is your workhorse. Read on.

How the ₹1.5 lakh limit works

The limit is ₹1,50,000 per tax year, combined across all eligible instruments. Invest ₹2 lakh across PPF and ELSS, and you still deduct only ₹1.5 lakh. The deduction reduces your taxable income, so the actual saving depends on your slab:

• At the 20% slab: up to ₹31,200 saved (including 4% cess)
• At the 30% slab: up to ₹46,800 saved

(Pension plan and your own NPS contributions, the old 80CCC and 80CCD(1), share this same ₹1.5 lakh limit; they count inside it, not on top of it. The extra ₹50,000 for NPS sits outside it.)

The main 80C instruments

EPF: the one you're already doing

Your Employees' Provident Fund contribution (the 12% of basic that vanishes from your payslip) counts towards 80C automatically. Many salaried people fill a big chunk of the limit without doing anything. Check your payslip before making fresh investments, or you'll over-invest for no benefit.

PPF: the safe, slow classic

Public Provident Fund: government-backed, tax-free interest, and a 15-year lock-in (partial withdrawals allowed after a few years, with conditions). Deposit between ₹500 and ₹1.5 lakh a year. Ideal for the conservative slice of your portfolio.

ELSS: the market-linked option

Equity Linked Savings Schemes are tax-saving mutual funds with the shortest lock-in of all: 3 years. Higher risk, historically higher returns. Note that each SIP instalment has its own 3-year lock-in.

Life insurance premiums

Premiums on policies for yourself, spouse or children qualify. Two warnings: the premium generally needs to stay within a percentage of the sum assured for the deduction (and for tax-free maturity), and surrendering too early can reverse the benefit, the fine print here is dense, so check with a CA before buying or exiting. And never buy insurance purely for 80C; a low-cost term plan plus separate investments usually beats bundled products.

Home loan principal repayment

The principal portion of your home-loan EMI qualifies under 80C (the interest goes under a different section, 24(b)). Stamp duty and registration charges paid in the year of purchase also count. One trap: sell the house within 5 years of possession and your earlier 80C claims on principal get reversed.

Children's tuition fees

Tuition fees paid to a school, college or university in India for up to two children. Only the tuition component, not donations, development fees, transport or hostel charges.

NSC: post office favourite

National Savings Certificates: 5-year lock-in, government-backed. The interest accrued each year (except the last) is deemed reinvested and itself qualifies for 80C, a small bonus most people miss.

SSY: for daughters

Sukanya Samriddhi Yojana: for a daughter under 10, among the highest small-savings interest rates, tax-free maturity. Long lock-in, the account matures 21 years from opening, but it's arguably the best debt instrument in the 80C basket if you're eligible.

Tax-saver FDs and others

5-year tax-saver fixed deposits (interest is taxable, unlike PPF), and Senior Citizens' Savings Scheme for those 60+, also qualify.

Lock-ins at a glance

• ELSS: 3 years (shortest)
• Tax-saver FD / NSC / SCSS: 5 years
• PPF: 15 years
• SSY: ~21 years from account opening
• Home purchase: hold 5 years or deductions reverse
• Insurance: effectively the policy term

Common mistakes to avoid

• Investing under section 123 while on the new regime. Money locked in for no tax benefit. Confirm your regime first.
• Ignoring EPF. If your EPF contribution is ₹1 lakh a year, you only need ₹50,000 more, not a fresh ₹1.5 lakh.
• The March panic purchase. Rushed decisions in the last week of March are how bad ULIPs and unnecessary endowment policies get sold. Spread investments across the year via SIP instead.
• Claiming home loan interest under 80C. Interest belongs to Section 24(b); only principal sits in 80C. Mixing them up can trigger notices.
• Counting every school fee. Bus fees, donations and building funds don't qualify, only tuition.
• Forgetting proofs at filing time. If your employer didn't capture a claim, you can still take it in your ITR, our ITR filing guide covers how, but keep receipts and statements in case of questions.

So should you invest for 80C at all?

Decide in this order:

1. Pick your regime with real numbers, not habit. For most people the new regime wins, and 80C becomes irrelevant for tax.
2. If the old regime genuinely suits you (big HRA, verify with the HRA exemption calculator, plus home loan and full deductions), then max out 80C, starting with what's automatic (EPF) and cheap (PPF/ELSS).
3. Either way, invest because the instrument fits your goals, not because a section number exists. A good investment that saves tax is a bonus; a bad investment that saves tax is still a bad investment.

That's Section 80C: powerful in the right regime, a paperweight in the wrong one. Know which side you're on before March does its thing.
