Every year, millions of Indian taxpayers face the same question: should I choose the new tax regime or the old one? The answer depends entirely on how many deductions you can claim. This guide gives you a clear framework to decide.
New Tax Regime - Lower Rates, Fewer Deductions
The new regime (default since FY 2023-24) offers lower tax slab rates. Income up to ₹12 lakh is effectively tax-free thanks to the Section 87A rebate. However, most deductions like 80C, 80D, HRA, and home loan interest are not available.
Old Tax Regime - Higher Rates, All Deductions
The old regime has higher base rates but allows you to claim all deductions - 80C (₹1.5L), 80D (health insurance), HRA, LTA, home loan interest (₹2L), NPS (₹50K), and more. You must actively opt-in to the old regime.
Side-by-Side Slab Comparison (FY 2026-27 / AY 2027-28)
The new regime slabs were revised in Budget 2025 (effective FY 2025-26) and retained in Budget 2026 for FY 2026-27. The old regime slabs are unchanged. All rates below exclude the 4% Health and Education Cess that applies on top.
| Income Slab (annual) | New Regime Rate | Old Regime Rate |
|---|---|---|
| Up to ₹4,00,000 | Nil | Nil up to ₹2.5L; 5% from ₹2.5L-₹4L |
| ₹4L - ₹5L | 5% | 5% (₹2.5L-₹5L) |
| ₹5L - ₹8L | 5% | 20% (₹5L-₹10L) |
| ₹8L - ₹10L | 10% | 20% |
| ₹10L - ₹12L | 10% | 30% (above ₹10L) |
| ₹12L - ₹16L | 15% | 30% |
| ₹16L - ₹20L | 20% | 30% |
| ₹20L - ₹24L | 25% | 30% |
| Above ₹24L | 30% | 30% |
Note: under the new regime, taxable income up to ₹12 lakh is effectively tax-free thanks to the Section 87A rebate of up to ₹60,000. Combined with the ₹75,000 standard deduction, salaried individuals earning up to ₹12.75 lakh pay nil tax. The 87A rebate in the old regime is much smaller (₹12,500 up to ₹5 lakh taxable income).
💰Break-Even Analysis - When Does Old Regime Win?
Income Below ₹12 Lakh
New regime always wins. With the 87A rebate, income up to ₹12L is tax-free. Even ₹12.75L is effectively tax-free after the ₹75K standard deduction. No amount of deductions in the old regime can beat zero tax.
Income ₹12L - ₹15 Lakh
New regime almost always wins in this band under FY 2026-27 slabs. With the ₹75,000 standard deduction and the wider 5% / 10% / 15% bands, a ₹15 lakh gross salary attracts roughly ₹94,000 of new-regime tax (before cess). To beat that under the old regime you typically need ₹4.5 lakh or more in combined deductions (full 80C + 80D + meaningful HRA + maybe NPS).
Income ₹15L - ₹20 Lakh
Old regime starts becoming competitive only when total deductions cross roughly ₹5-6 lakh. This is realistic for people paying high metro rent (large HRA), with a home loan in repayment and family health insurance. Below that threshold, the lower new-regime slab structure typically wins.
Income Above ₹20 Lakh
The 30% rate kicks in only above ₹24 lakh in the new regime, versus above ₹10 lakh in the old regime. That is a big structural advantage for the new regime - even at ₹25 lakh of gross salary, a sizeable portion of income is taxed at 25% or below. Old regime can still win, but only with substantial deductions (typically ₹6 lakh or more). Run both calculations before deciding.

Worked Examples at 3 Salary Levels
Example 1: ₹8 Lakh Salary
| Metric | New Regime | Old Regime |
|---|---|---|
| Gross salary | ₹8,00,000 | ₹8,00,000 |
| Standard deduction | ₹75,000 | ₹50,000 |
| 80C | N/A | ₹1,50,000 |
| Taxable income | ₹7,25,000 | ₹6,00,000 |
| Tax payable | ₹0 (87A rebate) | ₹32,500 |
Winner: New Regime - zero tax vs ₹32,500.
Example 2: ₹15 Lakh Salary
| Metric | New Regime | Old Regime |
|---|---|---|
| Gross salary | ₹15,00,000 | ₹15,00,000 |
| Standard deduction | ₹75,000 | ₹50,000 |
| 80C + 80D + HRA | N/A | ₹3,50,000 |
| Taxable income | ₹14,25,000 | ₹11,00,000 |
| Tax payable (before cess) | ~₹93,750 | ~₹1,42,500 |
New-regime tax breakdown: ₹4L-₹8L at 5% = ₹20,000; ₹8L-₹12L at 10% = ₹40,000; ₹12L-₹14.25L at 15% = ₹33,750. Total = ₹93,750 (plus 4% cess).
Winner: New Regime by roughly ₹48,750 - despite the old regime claiming ₹3.5L of deductions. The wider new-regime bands at FY 2026-27 rates make old regime hard to beat at this salary level unless deductions go materially higher.
Example 3: ₹25 Lakh Salary
| Metric | New Regime | Old Regime |
|---|---|---|
| Gross salary | ₹25,00,000 | ₹25,00,000 |
| Standard deduction | ₹75,000 | ₹50,000 |
| All deductions | N/A | ₹5,50,000 |
| Taxable income | ₹24,25,000 | ₹19,00,000 |
| Tax payable (before cess) | ~₹3,07,500 | ~₹3,82,500 |
New-regime tax breakdown: ₹4L-₹8L at 5% = ₹20,000; ₹8L-₹12L at 10% = ₹40,000; ₹12L-₹16L at 15% = ₹60,000; ₹16L-₹20L at 20% = ₹80,000; ₹20L-₹24L at 25% = ₹1,00,000; and only the ₹25,000 above ₹24L falls in the 30% slab, so ₹25,000 × 30% = ₹7,500. Total = ₹3,07,500 (plus 4% cess). Old-regime tax breakdown: ₹2.5L-₹5L at 5% = ₹12,500; ₹5L-₹10L at 20% = ₹1,00,000; ₹10L-₹19L at 30% = ₹2,70,000. Total = ₹3,82,500 (plus 4% cess).
Winner: New Regime by roughly ₹75,000 - even with a generous ₹5.5L of deductions in the old regime (80C + HRA + 80D + home loan + NPS). Note this conclusion assumes fully claimable deductions; if your actual claimable amount drops below ₹6L, the new regime advantage widens further.
🏠Can You Switch Every Year?
Salaried employees: Yes, you can switch between old and new regime every financial year. Inform your employer at the start of the year, or choose when filing your ITR.
Business/professional income: You can switch from new to old only once. After that, the choice is permanent.
Common Mistake to Avoid
The most common mistake is choosing the old regime without actually having enough deductions. Many people assume old regime is always better because they have heard about 80C and HRA. But under FY 2026-27 slabs, if your total deductions are under roughly ₹4-5 lakh, the new regime with its wider bands and ₹75K standard deduction is almost certainly better. The break-even point keeps shifting upwards as the new-regime structure widens. Always calculate both before deciding.
