Deductions are the old regime’s whole appeal
India’s old tax regime charges higher rates than the new one, so the only reason to choose it is the long list of deductions and exemptions it allows. Stack enough of them and your taxable income drops far enough that the old regime’s higher rates still produce a smaller bill than the new regime — even after the new regime’s generous ₹12 lakh rebate. This guide walks through the deductions that matter most, what they’re worth, and how to tell whether they actually beat the new regime for you.
Before diving in, one rule frames everything: almost none of these deductions exist in the new regime. If you’re on the new regime, your tax is essentially fixed by the slabs and rebate, and 80C investments won’t change it. So this whole guide is about the old-regime path. Run both paths in the Income Tax Calculator to see which one wins for your numbers, and read our new vs old regime guide for the big-picture comparison.
Section 80C — the ₹1.5 lakh workhorse
Section 80C is the deduction most people know. It lets you reduce taxable income by up to ₹1.5 lakh a year through a basket of approved instruments:
- EPF (Employees’ Provident Fund) — the slice deducted from your salary already counts.
- PPF (Public Provident Fund) — a 15-year government-backed scheme; see how it grows with a PPF calculator.
- ELSS mutual funds — equity funds with a three-year lock-in and market-linked returns.
- Life-insurance premiums — for policies on you, your spouse, or children.
- Home-loan principal — the principal portion of your EMI (not the interest, which is separate).
- Five-year tax-saver fixed deposits and NSC.
- Children’s tuition fees — for up to two children.
The ₹1.5 lakh is a shared ceiling: contributions across all of these add up against the same cap. Hit ₹1.5 lakh and further 80C contributions give no extra deduction.
Section 80D — health insurance
Health-insurance premiums are deductible under Section 80D, over and above the 80C limit:
- ₹25,000 for premiums covering yourself, your spouse, and dependent children.
- An additional ₹25,000 for insuring your parents — or ₹50,000 if they’re senior citizens.
So a person paying for their own family’s cover and their senior-citizen parents’ cover can claim up to ₹75,000. A preventive health check-up of up to ₹5,000 fits within these limits. It’s one of the most worthwhile deductions because you’re buying genuine protection, not just chasing a tax break.
House Rent Allowance (HRA)
If you’re salaried, rent a home, and receive HRA as part of your salary, you can claim an HRA exemption — often one of the largest deductions available to city renters. The exempt amount is the lowest of three figures: the actual HRA received, rent paid minus 10% of salary, and 50% of salary (40% in non-metro cities). The arithmetic trips people up, which is exactly what the HRA Calculator is for. Because HRA can run to lakhs for renters in expensive cities, it’s frequently the deduction that tips the balance toward the old regime.
Home-loan interest — Section 24(b)
Separate from the 80C principal deduction, Section 24(b) lets you deduct up to ₹2 lakh a year of interest paid on a home loan for a self-occupied property. For a large loan in its early years — when EMIs are mostly interest — this is a substantial reduction. Combined with the 80C principal deduction, a home loan can shelter a meaningful chunk of income.
The NPS top-up — Section 80CCD(1B)
The National Pension System offers an extra ₹50,000 deduction under Section 80CCD(1B), over and above the ₹1.5 lakh 80C limit. That makes it one of the few ways to push total deductions past ₹2 lakh. Notably, the employer’s NPS contribution under 80CCD(2) is the rare deduction that survives even in the new regime, so it’s worth asking your employer about.
Putting it together: does the old regime win?
Add up what you can realistically claim. A salaried city renter might reach: ₹1.5 lakh (80C) + ₹50,000 (NPS) + ₹50,000 (80D with senior parents) + ₹2 lakh (home-loan interest) + a large HRA exemption. That can easily total ₹4–6 lakh of deductions, dramatically shrinking old-regime taxable income.
Whether that beats the new regime depends on your income. The honest test is to compute both. Enter your income, tick salaried, and put your total deductions into the Income Tax Calculator — it shows the old and new regimes side by side and names the cheaper one. As a rough rule: with deductions above roughly ₹3.75–4 lakh, the old regime starts to compete; below that, the new regime’s lower rates and rebate usually win.
A sensible order of priority
If you’re starting from scratch, a reasonable sequence is: first max out anything you’d do anyway (EPF, health insurance, term life), then use ELSS or PPF to fill the 80C gap toward ₹1.5 lakh, add the ₹50,000 NPS top-up if you want the extra shelter, and claim HRA and home-loan interest if they apply. Always pick instruments that suit your goals — liquidity, risk, time horizon — rather than buying purely for the deduction.
Common mistakes to avoid
A few errors cost people money every year. The biggest is switching to the old regime without checking the maths — many taxpayers assume their deductions still win when the new regime’s bigger rebate has quietly overtaken them. Always compute both. Another is last-minute, poorly-chosen 80C investments in March: buying an endowment policy or locking money in a low-return product purely to hit ₹1.5 lakh often costs more in opportunity than it saves in tax. A third is forgetting deductions you already have — your EPF contribution and any term-insurance premium already count toward 80C, so you may need less fresh investment than you think.
Finally, keep your proof of investment. Deductions claimed without supporting documents can be disallowed on scrutiny, so retain receipts, premium statements, and rent agreements. Salaried taxpayers should declare these to their employer early so TDS is deducted correctly through the year rather than facing a shortfall at filing.
A quick worked example
Suppose you earn ₹14 lakh, are salaried, and can claim ₹1.5 lakh (80C), ₹50,000 (NPS), ₹25,000 (80D) and ₹1.6 lakh (HRA). That’s ₹3.85 lakh of deductions plus the ₹50,000 standard deduction, dropping old-regime taxable income to about ₹9.15 lakh. Compared against the new regime’s flat treatment of the same salary, the gap is now close — and only a side-by-side calculation reveals the winner. Plug the figures into the Income Tax Calculator and you’ll have the answer in seconds rather than guessing.
