New vs Old Tax Regime FY 2025-26 — When Each Wins

For FY 2025-26 (assessment year 2026-27), the New tax regime is the default for every Indian taxpayer. You can still opt for the Old regime if you have substantial deductions — but the maths has shifted significantly with Budget 2024 and 2025 amendments.

This guide gives you exact break-even numbers, worked examples at every income band, and a clear decision rule. By the end you'll know which regime is better for your income and deductions — verifiable to the rupee on our Income Tax Calculator.

TL;DR

• Below ₹12.75L gross: New regime almost always wins. The 87A rebate makes income up to ₹12L taxable (₹12.75L gross for salaried) effectively zero-tax.
• ₹12.75L to ₹50L gross: Depends on your deductions. Need ~₹4-5L+ of deductions for Old regime to beat New.
• Above ₹50L gross: Surcharge changes the maths; usually still depends on deduction level.
• Senior citizens with no deductions: New regime still wins.

If you don't have substantial deductions and aren't deeply familiar with HRA / home loan interest stacking, default to New regime.

The slabs side-by-side

New Regime (FY 2025-26)

| Income (₹) | Rate | | --- | --- | | Up to 4,00,000 | 0% | | 4,00,001 – 8,00,000 | 5% | | 8,00,001 – 12,00,000 | 10% | | 12,00,001 – 16,00,000 | 15% | | 16,00,001 – 20,00,000 | 20% | | 20,00,001 – 24,00,000 | 25% | | Above 24,00,000 | 30% |

• Standard deduction: ₹75,000 (salaried only)
• Section 87A rebate: full rebate up to ₹12L taxable income
• Available deductions: standard deduction, employer's NPS contribution under 80CCD(2), family pension. That's it.

Old Regime (FY 2025-26)

| Income (₹) | Below 60 | 60-80 | 80+ | | --- | --- | --- | --- | | Up to basic exemption | 0% | 0% | 0% | | Basic exemption ₹2.5L | ₹3L | ₹5L | | | Up to 5,00,000 | 5% | 5% | 5% | | 5,00,001 – 10,00,000 | 20% | 20% | 20% | | Above 10,00,000 | 30% | 30% | 30% |

• Standard deduction: ₹50,000 (salaried only)
• Section 87A rebate: full rebate up to ₹5L taxable income
• Available deductions: 80C (₹1.5L), 80D (medical insurance), HRA, LTA, home loan interest (Section 24, up to ₹2L for self-occupied), education loan interest (80E), donations (80G), and many more.

Common to both

• 4% Health & Education Cess on (tax + surcharge).
• Surcharge: 10% above ₹50L, 15% above ₹1Cr, 25% above ₹2Cr. Old regime adds 37% above ₹5Cr; New caps at 25%.
• "Marginal relief" — when income just barely crosses a surcharge threshold, the extra surcharge is reduced so net income doesn't decrease.

Worked example: ₹15L gross, no deductions

The classic test case. Let's see what each regime does to a ₹15L gross income with only the standard deduction.

New regime

• Taxable: 15L − 75K = ₹14,25,000
• Slab tax:
  • 0-4L: ₹0
  • 4-8L (5%): ₹20,000
  • 8-12L (10%): ₹40,000
  • 12-14.25L (15%): ₹33,750
• Total tax (before cess): ₹93,750
• Cess (4%): ₹3,750
• Total tax: ₹97,500

Old regime

• Taxable: 15L − 50K = ₹14,50,000
• Slab tax:
  • 0-2.5L: ₹0
  • 2.5-5L (5%): ₹12,500
  • 5-10L (20%): ₹1,00,000
  • 10-14.5L (30%): ₹1,35,000
• Total tax (before cess): ₹2,47,500
• Cess (4%): ₹9,900
• Total tax: ₹2,57,400

New regime saves you ₹1,59,900 on a ₹15L income with no deductions. The Old regime would need a huge deduction stack to close that gap.

Worked example: ₹15L gross, ₹4L deductions

Same income, but now with ₹1.5L 80C + ₹50K 80D + ₹2L home loan interest = ₹4L of deductions.

New regime

Same as before: ₹97,500. New regime ignores the deductions.

Old regime

• Taxable: 15L − 50K (std) − 4L (other) = ₹10,50,000
• Slab tax:
  • 0-2.5L: ₹0
  • 2.5-5L (5%): ₹12,500
  • 5-10L (20%): ₹1,00,000
  • 10-10.5L (30%): ₹15,000
• Total tax (before cess): ₹1,27,500
• Cess (4%): ₹5,100
• Total tax: ₹1,32,600

Even with ₹4L deductions, Old regime is still ₹35K worse than New for this income. You'd need ~₹5.5L+ of deductions for Old to beat New at ₹15L.

When does Old actually win?

The break-even varies by income. Here's the approximate deduction threshold above which Old regime wins:

| Gross income | Deductions needed for Old to win | Realistic to achieve? | | --- | --- | --- | | ₹10L | Old never wins (87A rebate) | N/A | | ₹12L | Old never wins (87A rebate) | N/A | | ₹15L | ~₹5.5L | Hard, needs HRA + home loan + 80C | | ₹20L | ~₹6L | Plausible for big-city renters | | ₹25L | ~₹6.5L | Yes if HRA + 80C + 80D + home loan | | ₹50L | ~₹8L | Yes for many high earners | | ₹1Cr+ | ~₹10L+ | Yes — HRA alone can be ₹3-4L+ |

Rough rule: if your total deductions (everything you can claim under 80C, 80D, 80E, 80G, HRA, LTA, Section 24) is below 30-35% of your gross income, New regime usually wins.

What deductions can boost Old regime?

If you're seriously considering Old regime, here's the deduction stack that high earners typically build:

| Deduction | Maximum | Realistic for ₹20L+ earners | | --- | --- | --- | | Section 80C (PPF/ELSS/EPF/insurance) | ₹1,50,000 | Easy — most fill this | | Section 80D (medical insurance) | ₹25K-1L | ₹50-75K typical | | HRA exemption | Salary-based | ₹2-4L for big-city renters | | Home loan interest (Sec 24) | ₹2,00,000 | Yes if you own | | LTA | Travel-based | ₹50K-1L if you actually travel | | 80CCD(1B) — extra NPS | ₹50,000 | ₹50K | | 80E — education loan interest | No cap | Variable | | Standard deduction | ₹50,000 | Auto |

A salaried renter in Mumbai/Bangalore with home in their hometown (HRA + home loan interest) plus full 80C + 80D + NPS can easily stack ₹7-8L of deductions and beat New regime.

The 87A rebate trap

A subtle gotcha: the rebate cuts off sharply at ₹12L (New) or ₹5L (Old) taxable income. If you're at ₹12.05L taxable, you owe a small tax on the slab portion above ₹12L — but the rebate disappears entirely, so your jump from ₹12L → ₹12.05L could mean your tax goes from ₹0 → ₹61,000.

This is now mitigated by "marginal relief" introduced in Budget 2025: if crossing the threshold makes your post-tax income lower than someone earning just below the threshold, the tax is capped so you never end up worse off. But the rule only kicks in within a narrow band — once you're well above ₹12L, you pay the full slab tax.

For most filers, this means: aim to either stay well below ₹12L or just accept the tax.

What about HUFs, NRIs, business income?

• HUF (Hindu Undivided Family): Both regimes available, same slabs as below-60 individuals.
• NRIs: Eligible for both regimes. Most NRIs benefit from New regime since HRA/home loan exemptions don't apply if they don't reside in India.
• Business / freelance / self-employed: You can choose either regime, but switching back to Old after picking New is allowed only once in a lifetime (whereas salaried can switch each year).

Self-employed people without business deductions almost always pick New regime. Those with depreciation-heavy businesses and 80C investments may prefer Old.

Senior citizens (60+ and 80+)

Higher basic exemption helps Old regime, but New regime's 87A rebate of ₹12L+ usually still wins for typical retiree incomes (pension, FD interest, dividend). Old becomes attractive only if you have huge medical insurance premiums (80D up to ₹50K for seniors) or significant LTCG/STCG.

Decision flow

1. Income ≤ ₹7L? New regime, zero tax under 87A. Done.
2. Income ≤ ₹12.75L (gross, salaried)? New regime. Zero tax under 87A.
3. Income > ₹12.75L? Add up your potential deductions (80C + 80D + HRA + Sec 24 + others). If total > 30-35% of gross, Old likely wins. Run both regimes to be sure.
4. High earner with massive HRA + home loan + 80C stack? Old usually wins. Run the numbers.

Mid-year switching

Salaried employees can switch regimes every financial year when filing. Your employer may withhold based on whichever you declared at the start of the year, but you can switch at filing time. If your employer is deducting under New but you'd benefit from Old, file Old at year-end and claim a refund.

Self-employed and business income earners have stricter rules — once you opt for New regime, switching back to Old is allowed only once in a lifetime.

Bottom line

For FY 2025-26, the New regime is the right answer for the majority of Indian taxpayers — especially those who don't have HRA, don't own a home with a loan, or don't otherwise have a large deduction stack.

Always verify by running both regimes. Use our Income Tax Calculator — it shows you the side-by-side comparison automatically and recommends the lower-tax option.

The single biggest mistake people make: sticking with Old regime out of habit, even when their deductions don't justify it. Check every year — your situation can change with a job change, a home loan, or a city move.
