Section 80C of the Income Tax Act lets you subtract certain investments and expenses from your taxable income. For FY 2026-27 you can deduct up to ₹1.5 lakh in a financial year – a single combined cap covering everything from PPF and EPF to life-insurance premiums, ELSS, home-loan principal and children's tuition – and it is available only under the old tax regime. Cross ₹1.5 lakh in total and the extra earns nothing under 80C.
The mistake people make is treating 80C as a shopping list where each item adds its own deduction. It is one ceiling, shared by everything.
Section 80C at a glance
What qualifies for a Section 80C deduction?
The eligible list is wide, mixing investments with everyday expenses. Common items include:
- EPF – your own contribution to the Employees' Provident Fund, usually already deducted from salary.
- PPF – the Public Provident Fund, a 15-year government-backed account.
- ELSS – equity-linked savings scheme mutual funds, with a three-year lock-in.
- Life-insurance premiums – for yourself, spouse or children.
- Five-year tax-saving fixed deposits and National Savings Certificate (NSC).
- Sukanya Samriddhi Yojana – a scheme for a girl child.
- Home-loan principal repayment, and stamp duty and registration paid on buying a home.
- Tuition fees – for up to two children, for full-time education in India.
Each of these counts toward the same ₹1.5 lakh. This is a list of what qualifies, not a ranking. Which categories suit a given person depends on their goals, time horizon and risk comfort, and that is not something a tax section decides.
Is 80C available under the new tax regime?
No. The 80C deduction sits entirely in the old regime. The new regime – the default since FY 2023-24 – removes 80C along with most other deductions, in exchange for lower slab rates. Under the new regime, money put into PPF, ELSS or a tax-saving FD still grows on its own terms, but it earns no 80C benefit.
So the first question is never "which 80C option is best". It is which regime you are in, because under the new one the section does not apply at all.
Does 80C cut your tax or your income?
It cuts taxable income, and that distinction matters. A full ₹1.5 lakh claim reduces the income on which tax is charged, so the tax saved is ₹1.5 lakh multiplied by your marginal rate.
| Marginal slab | Full ₹1.5 lakh claim reduces tax by (illustrative) |
|---|---|
| 5% | ₹7,500 |
| 20% | ₹30,000 |
| 30% | ₹45,000 |
The figures above are illustrative and ignore cess and surcharge. The same claim is worth six times as much at 30% as at 5% – which is exactly why 80C is an old-regime feature, since the old regime is where higher earners trade deductions against higher rates.
How does 80C sit against other deductions?
80C does not stand alone. Two related sections share its ceiling: 80CCC, for contributions to certain pension plans, and 80CCD(1), for an employee's own contribution to the National Pension System. Together with 80C, these three are capped at the same ₹1.5 lakh. Outside that ceiling, 80CCD(1B) offers a separate deduction of up to ₹50,000 for additional NPS contributions, and Section 80D covers health-insurance premiums under its own limits. All of these are old-regime deductions with their own conditions. The point is not to stack them, but to know that the ₹1.5 lakh 80C figure is a shared pool, not a fresh limit for every instrument.
The ₹1.5 lakh trap most people miss
Because EPF is deducted automatically from salary, many people have already used a large slice of their ₹1.5 lakh before they invest a rupee elsewhere. Add home-loan principal and a child's tuition, and the limit can be full without any deliberate "tax-saving" investment at all.
That is the practical point of understanding 80C: not to chase the cap, but to see how much of it your existing commitments already fill. The 80C optimiser helps you total up what already counts.

80C is one door with a ₹1.5 lakh limit, not a corridor of separate windows. Knowing what already flows through it – EPF, tuition, home-loan principal – tells you far more than any list of "best" investments ever could.
