Section 80C is Now Section 123: What Taxpayers Must Know

What actually changed

Section 80C has been the backbone of tax planning for Indian taxpayers for decades, the ₹1.5 lakh bucket you fill with PPF, ELSS, insurance and the rest. Under the Income Tax Act, 2025, that provision has been renumbered as Section 123, sitting in the new Chapter VIII.

Two things are worth being clear about. First, the benefit is unchanged: the same ₹1,50,000 limit, the same eligible investments, the same rules. Second, the structure is tidier. Instead of a long list embedded in the section text, all the eligible instruments are now collected in a single reference table, Schedule XV. The section states the limit; the schedule holds the list.

There is one behind-the-scenes consolidation. The old Sections 80C, 80CCC (pension funds) and 80CCD(1) (NPS employee contribution) have been folded together under Section 123, sharing the one ₹1.5 lakh cap, exactly as they effectively did before.

What still qualifies under Section 123

Every instrument you knew under 80C continues to qualify under Section 123. The familiar list:

The ₹1.5 lakh is a combined cap across all of these, not per instrument. Investing more than ₹1.5 lakh in total does not increase the deduction. This is a deduction against your income, not a rebate against your final tax, so its value depends on your slab.

The old-regime-only rule

This is the single most important thing to understand, and it is unchanged from the 80C days: Section 123 deductions are available only under the old tax regime. If you are on the new regime, which has been the default for a few years now, you cannot claim Section 123 at all. You get the ₹75,000 standard deduction and little else.

So to use your PPF, ELSS or LIC deductions, you must explicitly opt for the old regime when filing (the old regime is chosen against the new default under the renumbered Section 202). Whether that is worth it depends entirely on your numbers.

The extra ₹50,000 NPS deduction

The popular extra deduction for NPS, the additional ₹50,000 over and above the ₹1.5 lakh, has also moved. What was Section 80CCD(1B) is now Section 124(3). It survives intact: you can still claim up to ₹50,000 for NPS contributions on top of the Section 123 limit, taking your total potential deduction to ₹2 lakh.

Employer NPS contributions sit under a separate provision again (the renumbered equivalent of 80CCD(2)) and are the one meaningful deduction that even the new regime allows. If NPS is part of your plan, it is worth structuring correctly, both the employee and employer legs.

A worked example

Take Priya, a salaried professional earning ₹12 lakh who opts for the old regime. Her EPF (her own contribution) already puts ₹60,000 into the Section 123 bucket. She adds ₹40,000 to PPF and ₹50,000 into ELSS, filling the ₹1.5 lakh limit exactly. She then contributes ₹50,000 to NPS, claiming it under Section 124(3).

Her total deduction is ₹2 lakh, ₹1.5 lakh under Section 123 plus ₹50,000 under Section 124(3), reducing her taxable income to ₹10 lakh before other deductions. Nothing about how she invests changed from the 80C era; only the section numbers on her return are different, and her software applies them automatically.

The lesson: the mechanics of tax-saving are identical. Fill the ₹1.5 lakh bucket, use the extra ₹50,000 NPS room if you can spare it, and make sure you are on the regime where these deductions actually count.

Common mistakes to avoid

A few errors catch people out every year, and the renumbering does not change them:

• Claiming Section 123 on the new regime. Not allowed. You must be on the old regime for it to apply. This is the most common and most expensive mistake.
• Counting the employer's EPF contribution. Only your (the employee's) EPF contribution qualifies under Section 123. The employer's share does not count toward the ₹1.5 lakh.
• Life insurance premium above 10% of sum assured. For policies issued after 1 April 2012, only the premium up to 10% of the sum assured is eligible; the excess is not.
• Claiming ELSS in the wrong year. ELSS is deductible in the year you invest, not the year you redeem.
• Assuming more than ₹1.5 lakh helps. The cap is firm. Investing beyond it is fine for savings, but earns no extra deduction.

If you would rather not track any of this, our income tax and ITR filing service optimises your deductions and picks the right regime on every return.

Quick answers

Is 80C still valid? Its subject matter now lives in Section 123, same ₹1.5 lakh, same investments. Where is the list of eligible investments? In Schedule XV of the 2025 Act. Can I claim it under the new regime? No, old regime only. What about the extra NPS ₹50,000? That is now Section 124(3), still available on top. Does my July 2026 return use Section 80C or 123? Still 80C, because it covers income earned before April 2026 under the old Act. See our full section mapping for the rest.
