AY 2026-27 (FY 2025-26). Reflects Budget 2025 new-regime slabs and the unchanged old-regime structure. Last reviewed 7 May 2026.
In AY 2024-25 the regime crossover for salaried taxpayers was widely quoted as "around ₹17-20 LPA" — beyond which the old regime's deductions started overcoming the new regime's lower rates. Budget 2025 broke that rule. The new regime's slabs were widened again, the 87A rebate was lifted to ₹12 lakh, and the 30% slab now starts at ₹24 lakh of taxable income. The result: ₹20 LPA is now squarely a new-regime profile, not a borderline case.
This guide walks through five common ₹20 LPA scenarios — from "no investments" to "full deduction stack" — and shows that the new regime wins all five.
Base case — only standard deduction
| Component | Old regime | New regime |
|---|---|---|
| Gross salary | ₹20,00,000 | ₹20,00,000 |
| Standard deduction | (₹50,000) | (₹75,000) |
| Other deductions | — | — |
| Taxable | ₹19,50,000 | ₹19,25,000 |
| Slab tax | ₹4,10,000 | ₹1,85,000 |
| 4% cess | ₹16,400 | ₹7,400 |
| Tax payable | ₹4,26,400 | ₹1,92,400 |
Gap: new regime wins by ₹2,34,000. With no investments at all, the old regime is structurally crushing.
Realistic floor — basic 80C + 80D
Most ₹20L earners have at least the EPF-fed 80C and a basic 80D for self and parents.
| Old regime | New regime | |
|---|---|---|
| Gross | ₹20,00,000 | ₹20,00,000 |
| Standard deduction | (₹50,000) | (₹75,000) |
| 80C | (₹1,50,000) | — |
| 80D | (₹25,000) | — |
| Taxable | ₹17,75,000 | ₹19,25,000 |
| Slab tax | ₹3,45,000 | ₹1,85,000 |
| 4% cess | ₹13,800 | ₹7,400 |
| Tax payable | ₹3,58,800 | ₹1,92,400 |
Gap: new regime wins by ₹1,66,400. ₹1.75L of deductions reduces old-regime tax by less than the new regime's structural advantage saves.
Renter — HRA + 80C + 80D, no home loan
A Mumbai or Delhi tenant paying ₹50,000/month rent. Basic ₹10L (50% of CTC), HRA ₹4L. Annual rent ₹6L. Mumbai is metro for HRA, so the third leg of the formula is 50% of basic.
HRA exemption (lowest of three): min(₹4L actual, ₹6L − ₹1L = ₹5L, 50% × ₹10L = ₹5L) = ₹4L.
| Old regime | New regime | |
|---|---|---|
| Gross | ₹20,00,000 | ₹20,00,000 |
| Standard deduction | (₹50,000) | (₹75,000) |
| HRA exemption | (₹4,00,000) | — |
| 80C | (₹1,50,000) | — |
| 80D | (₹25,000) | — |
| Taxable | ₹13,75,000 | ₹19,25,000 |
| Slab tax | ₹2,25,000 | ₹1,85,000 |
| 4% cess | ₹9,000 | ₹7,400 |
| Tax payable | ₹2,34,000 | ₹1,92,400 |
Gap: new regime wins by ~₹41,600. Even ₹4L of HRA exemption — substantial — cannot overcome the new regime's slab structure at this income.
Home-owner — full 80C + 80D + Section 24(b), no HRA
A homeowner with ₹4L of annual home-loan interest (₹2L claimable under Section 24(b)) on a self-occupied property.
| Old regime | New regime | |
|---|---|---|
| Gross | ₹20,00,000 | ₹20,00,000 |
| Standard deduction | (₹50,000) | (₹75,000) |
| 80C | (₹1,50,000) | — |
| 80D | (₹25,000) | — |
| 24(b) interest | (₹2,00,000) | — |
| Taxable | ₹15,75,000 | ₹19,25,000 |
| Slab tax | ₹2,85,000 | ₹1,85,000 |
| 4% cess | ₹11,400 | ₹7,400 |
| Tax payable | ₹2,96,400 | ₹1,92,400 |
Gap: new regime wins by ~₹1,04,000.
Full stack — HRA + 80C + 80D + Section 24(b) + 80CCD(1B)
The most aggressive realistic old-regime profile: a homeowner who rents in another city for work, plus full 80C, 80D, NPS Tier 1 voluntary, and home-loan interest.
| Old regime | New regime | |
|---|---|---|
| Gross | ₹20,00,000 | ₹20,00,000 |
| 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 | ₹13,25,000 | ₹19,25,000 |
| Slab tax | ₹2,10,000 | ₹1,85,000 |
| 4% cess | ₹8,400 | ₹7,400 |
| Tax payable | ₹2,18,400 | ₹1,92,400 |
Gap: new regime still wins by ~₹26,000. Even with ₹6.25 lakh of stacked deductions, the old regime can't quite catch up.
The break-even at ₹20 LPA requires roughly ₹6.5 lakh of deductions — uncommonly high outside the joint home-loan / metro-rent / NPS profile.

What this means for your decision
For nearly every ₹20 LPA profile in AY 2026-27, the new regime is the right answer. The exceptions are narrow and require all of: real metro-level HRA exemption, full 80C, 80D, NPS 80CCD(1B), and active home-loan interest near the ₹2L cap — and even then, the gap is small enough that a single assumption shift (rent dropping, loan being prepaid, NPS lapsing) flips it.
Most ₹20 LPA earners on the old regime today are there from inertia — declared old at the start of FY 2024-25 and never recomputed after Budget 2025. The single most useful tax move at this income is to recompute and switch.

Warning
At ₹20 LPA you are still below the surcharge threshold (₹50L), so the slab tax above is the complete picture for slab-rate income. Capital gains, lottery, and crypto income are taxed independently — add them separately to your total tax.
FAQ
The follow-up questions people usually ask after the main recommendation is already clear.
What is the income tax on ₹20 lakh salary in 2026?
Under the AY 2026-27 new regime with only the ₹75,000 standard deduction, tax on ₹20 lakh gross salary is approximately ₹1,92,400 (including 4% cess). Under the old regime with basic deductions of ₹1.5L 80C and ₹25K 80D, tax is approximately ₹3,58,800. The new regime wins by ~₹1,66,400.
Should I choose old or new regime for ₹20 LPA?
The new regime wins comfortably for almost every ₹20 LPA profile in AY 2026-27. Even with HRA exemption, full 80C, 80D, ₹50K of 80CCD(1B), and ₹2L of home-loan interest stacked together, the old regime still loses by approximately ₹40,000-60,000. At this income, the old regime is rarely the right choice.
Why does the new regime beat the old regime at ₹20L despite the old regime's deductions?
Two reasons. First, Budget 2025 widened the new regime's slabs significantly — the 30% rate doesn't kick in until ₹24L taxable income. Second, the standard deduction is ₹75K in the new regime vs ₹50K in the old regime. Together, these produce structural tax savings that even a fully stacked old-regime deduction profile cannot match at this income level.
Does NPS 80CCD(1B) tip the balance toward the old regime at ₹20L?
It narrows the gap but rarely closes it. Adding ₹50,000 of 80CCD(1B) deduction (available only in the old regime) reduces old-regime tax by approximately ₹15,600 at the 30% slab. Even with this added to the full-stack profile, the new regime still wins by roughly ₹40,000-45,000 at ₹20 LPA.
