AY 2026-27 (FY 2025-26). Reflects Budget 2025 new-regime slabs and the unchanged old-regime structure. Last reviewed 7 May 2026.
For most of AY 2024-25, ₹25 LPA was the income at which the old vs new regime debate became genuinely close. A homeowner in a metro with HRA, 80C, 80D, and home-loan interest could clear the new regime by ₹10,000-20,000 a year. Budget 2025 changed that. The new regime's slabs widened, the 87A rebate climbed to ₹12 lakh, and the structural advantage at ₹25 LPA is now significant — typically ₹1.95 lakh over a basic deduction profile, and still ~₹50,000+ over a fully stacked one.
This guide walks through five common ₹25 LPA scenarios. The new regime wins all of them except a narrow joint-home-loan case.
Base case — only standard deduction
| Component | Old regime | New regime |
|---|---|---|
| Gross salary | ₹25,00,000 | ₹25,00,000 |
| Standard deduction | (₹50,000) | (₹75,000) |
| Other deductions | — | — |
| Taxable | ₹24,50,000 | ₹24,25,000 |
| Slab tax | ₹5,60,000 | ₹3,07,500 |
| 4% cess | ₹22,400 | ₹12,300 |
| Tax payable | ₹5,82,400 | ₹3,19,800 |
Gap: new regime wins by ₹2,62,600. Without any deductions, the old regime is structurally far worse.
Realistic floor — basic 80C + 80D
| Old regime | New regime | |
|---|---|---|
| Gross | ₹25,00,000 | ₹25,00,000 |
| Standard deduction | (₹50,000) | (₹75,000) |
| 80C | (₹1,50,000) | — |
| 80D | (₹25,000) | — |
| Taxable | ₹22,75,000 | ₹24,25,000 |
| Slab tax | ₹4,95,000 | ₹3,07,500 |
| 4% cess | ₹19,800 | ₹12,300 |
| Tax payable | ₹5,14,800 | ₹3,19,800 |
Gap: new regime wins by ₹1,95,000. This is the most common ₹25 LPA outcome and reflects the headline gap most users encounter.
Renter — HRA + 80C + 80D, no home loan
A Mumbai or Delhi tenant paying ₹60,000/month rent. Basic ₹12.5L (50% of CTC), HRA ₹5L. Annual rent ₹7.2L. Mumbai is metro, so the third leg is 50% of basic.
HRA exemption: min(₹5L actual, ₹7.2L − ₹1.25L = ₹5.95L, 50% × ₹12.5L = ₹6.25L) = ₹5L.
| Old regime | New regime | |
|---|---|---|
| Gross | ₹25,00,000 | ₹25,00,000 |
| Standard deduction | (₹50,000) | (₹75,000) |
| HRA exemption | (₹5,00,000) | — |
| 80C | (₹1,50,000) | — |
| 80D | (₹25,000) | — |
| Taxable | ₹17,75,000 | ₹24,25,000 |
| Slab tax | ₹3,45,000 | ₹3,07,500 |
| 4% cess | ₹13,800 | ₹12,300 |
| Tax payable | ₹3,58,800 | ₹3,19,800 |
Gap: new regime still wins by ~₹39,000. Even ₹5L of HRA exemption — among the largest legitimately claimable on a ₹25 LPA salary — cannot overcome the new regime's wider slabs.
Home-owner — full 80C + 80D + Section 24(b) + NPS 80CCD(1B), no HRA
A self-occupied homeowner with ₹4L+ of home-loan interest (₹2L claimable). Adds ₹50K of voluntary NPS contribution under 80CCD(1B), available only in the old regime.
| Old regime | New regime | |
|---|---|---|
| Gross | ₹25,00,000 | ₹25,00,000 |
| Standard deduction | (₹50,000) | (₹75,000) |
| 80C | (₹1,50,000) | — |
| 80D | (₹25,000) | — |
| 80CCD(1B) | (₹50,000) | — |
| 24(b) interest | (₹2,00,000) | — |
| Taxable | ₹20,25,000 | ₹24,25,000 |
| Slab tax | ₹4,20,000 | ₹3,07,500 |
| 4% cess | ₹16,800 | ₹12,300 |
| Tax payable | ₹4,36,800 | ₹3,19,800 |
Gap: new regime wins by ~₹1,17,000.
Full stack — HRA + home loan + NPS + full 80C + 80D
The aggressive single-earner profile: rents in one city, owns in another. ₹2L HRA exemption, ₹2L home-loan interest, all old-regime extras.
| Old regime | New regime | |
|---|---|---|
| Gross | ₹25,00,000 | ₹25,00,000 |
| Standard deduction | (₹50,000) | (₹75,000) |
| HRA exemption | (₹2,00,000) | — |
| 80C | (₹1,50,000) | — |
| 80D | (₹25,000) | — |
| 80CCD(1B) | (₹50,000) | — |
| 24(b) interest | (₹2,00,000) | — |
| Taxable | ₹18,25,000 | ₹24,25,000 |
| Slab tax | ₹3,60,000 | ₹3,07,500 |
| 4% cess | ₹14,400 | ₹12,300 |
| Tax payable | ₹3,74,400 | ₹3,19,800 |
Gap: new regime still wins by ~₹54,600. Even with ₹6.75 lakh of deductions stacked, the old regime falls short.
When the old regime can win at ₹25 LPA — the joint home loan case
A profile where the old regime clearly beats the new: married couple, both in the 30% slab, joint home loan on a self-occupied property. Each spouse files independently and each claims ₹2L of Section 24(b) interest plus ₹1.5L of 80C principal.
For one spouse with ₹25L salary:
| Old regime | New regime | |
|---|---|---|
| Gross | ₹25,00,000 | ₹25,00,000 |
| Standard deduction | (₹50,000) | (₹75,000) |
| HRA exemption | (₹0) | — |
| 80C (incl. principal) | (₹1,50,000) | — |
| 80D | (₹25,000) | — |
| 80CCD(1B) | (₹50,000) | — |
| 24(b) interest | (₹2,00,000) | — |
| Taxable | ₹20,25,000 | ₹24,25,000 |
| Tax payable | ₹4,36,800 | ₹3,19,800 |
Wait — even here, new regime wins by ~₹1.17L on this side. The joint old-regime case wins at the household level only when both spouses are at ₹25L and the loan interest is large enough that both can claim ₹2L cleanly. Run both households through the calculator.

What this means for your decision
The headline at ₹25 LPA in AY 2026-27: the new regime wins for almost every realistic single-earner profile, by ₹40K to ₹2L depending on your deduction stack. The remaining old-regime cases require very specific, simultaneous conditions — joint home loan with both spouses in the 30% slab, real metro HRA on a high-basic salary, and active 80CCD(1B) participation — and even then the household-level gap is small.
If you're inertia-staying on the old regime at ₹25 LPA in 2026, recompute. The post-Budget-2025 math has moved against the old regime more than most professionals realise.

Warning
At ₹25 LPA you are still below the ₹50L surcharge threshold. Slab tax + cess captures the full picture for slab-rate income. Capital gains and other special-rate income are taxed independently.
FAQ
The follow-up questions people usually ask after the main recommendation is already clear.
What is the income tax on ₹25 lakh salary in 2026?
Under the AY 2026-27 new regime with only the ₹75,000 standard deduction, tax on ₹25 lakh gross salary is approximately ₹3,19,800 (including 4% cess). Under the old regime with basic deductions (₹1.5L 80C + ₹25K 80D), tax is approximately ₹5,14,800. The new regime wins by ~₹1,95,000 — the largest absolute gap of any common income band before surcharge enters the picture.
When does the old regime win at ₹25 LPA?
The old regime narrowly wins only when the deduction stack clears roughly ₹7 lakh — HRA exemption (~₹2L+), full 80C (₹1.5L), 80D (₹25K), NPS 80CCD(1B) (₹50K), and Section 24(b) home-loan interest (₹2L), all real and active in the same financial year. Most ₹25 LPA profiles don't have all of these simultaneously. The cleanest old-regime winner is a joint home-loan profile where both spouses claim 24(b) interest and 80C principal independently.
Should I switch from old to new regime at ₹25 LPA after Budget 2025?
Likely yes. Budget 2025 widened the new regime's slabs further and lifted the 87A rebate to ₹12L — the structural advantage is now ~₹2L per year for typical profiles. If you've been on the old regime since FY 2023-24 or earlier, recompute under Budget 2025 slabs before declaring for FY 2026-27. The single most common reason ₹25 LPA earners stay on the old regime in 2026 is inertia, not optimal math.
Does adding 80CCD(2) employer NPS change the regime choice at ₹25 LPA?
Yes, in favour of the new regime. Section 80CCD(2) employer NPS contribution — up to 14% of basic salary — is deductible in both regimes but only the new regime gets the 14% cap (the old regime cap is 10% for private-sector employees). At ₹25 LPA with ₹12.5L basic, the 14% cap permits ₹1.75L of 80CCD(2) deduction in the new regime versus ₹1.25L in the old. That ₹50K differential at the 30% marginal rate widens the new regime's lead by ~₹15,600.
