New vs Old Tax Regime FY 2025-26 — Which One Should You Choose?

📅 IT Act 2025 transition note: This page covers FY 2025-26 (AY 2026-27) — the last cycle under the Income-tax Act, 1961. From 1 April 2026 (Tax Year 2026-27), the Income-tax Act, 2025 comes into force per Section 536. The Finance Act 2025 slab rates + Section 87A ₹60,000 rebate + ₹75,000 standard deduction described below carry forward substantively unchanged. Section references in your ITR for AY 2026-27 remain 1961 Act numbering. See the IT Act 2025 transition reference for the full mapping.

What changed in Budget 2025

The Finance Act 2025 aggressively positioned the new tax regime as the undisputed default for the vast majority of Indian taxpayers. By widening the tax slabs, hiking the standard deduction, and introducing an unprecedented Section 87A rebate, the Government aimed to put more disposable income directly into the hands of the middle class without requiring them to lock money into specific tax-saving investments.

For a salaried taxpayer, FY 2025-26 (AY 2026-27) brings three structural incentives to stick with the new regime:

1. The ₹60,000 rebate: income up to ₹12,00,000 is effectively tax-free.
2. Higher standard deduction: increased from ₹50,000 to ₹75,000.
3. Lower rates at higher brackets: the peak 30% rate now only triggers above ₹24,00,000.

However, the old tax regime remains active. For taxpayers servicing large home loans and paying high rent, crunching the numbers is still essential before filing.

Slab tables — side by side (FY 2025-26)

The foundational difference between the two regimes lies in the tax brackets. The new regime offers a lower rate of taxation across the board but prohibits most exemptions.

Income bracket	New regime (default)	Old regime (optional)
Up to ₹2,50,000	NIL	NIL
₹2,50,001 to ₹4,00,000	NIL	5%
₹4,00,001 to ₹5,00,000	5%	5%
₹5,00,001 to ₹8,00,000	5%	20%
₹8,00,001 to ₹10,00,000	10%	20%
₹10,00,001 to ₹12,00,000	10%	30%
₹12,00,001 to ₹16,00,000	15%	30%
₹16,00,001 to ₹20,00,000	20%	30%
₹20,00,001 to ₹24,00,000	25%	30%
Above ₹24,00,000	30%	30%

Note: under the old regime, the basic exemption is ₹2,50,000 for individuals < 60 years; ₹3,00,000 for senior citizens (60–79); ₹5,00,000 for super senior citizens (80+). Under the new regime, the ₹4,00,000 exemption applies to everyone regardless of age.

Section 87A rebate — the zero-tax threshold

Section 87A is a direct discount on your final calculated tax. It completely wipes out tax liability if total taxable income falls below a specific threshold.

Under the new regime (FY 2025-26): The rebate is capped at ₹60,000. It applies if taxable income is ₹12,00,000 or less. Because salaried individuals also get a ₹75,000 standard deduction, a salaried person can earn a gross income of ₹12,75,000, reduce it to ₹12,00,000 via the standard deduction, and owe zero tax.

Marginal relief: if income slightly exceeds ₹12,00,000 (say, ₹12,10,000), the tax payable is restricted so that it does not exceed the income earned above the ₹12,00,000 mark.

Under the old regime: The rebate remains capped at ₹12,500. It only applies if total taxable income (after all 80C, HRA, etc., deductions) is ₹5,00,000 or less.

Standard deduction + surcharge differences

Beyond slabs and rebates, the mechanics of calculating final payable tax differ slightly.

Standard deduction:

• New regime: ₹75,000 (salaried + pensioners). Family pensioners get a deduction of ₹25,000 or 1/3rd of the pension, whichever is lower.
• Old regime: ₹50,000.

Surcharge caps: High-net-worth individuals face a surcharge on their income tax.

• New regime: highest surcharge rate capped at 25% (for income > ₹2 crore).
• Old regime: highest surcharge remains at 37% (for income > ₹5 crore).

Both regimes attract a flat 4% Health & Education Cess on top of tax + surcharge.

Deductions you LOSE under new regime

To access the lower tax rates of the new regime, Section 115BAC requires you to surrender approximately 70 different exemptions and deductions. The most impactful ones you cannot claim include:

1. Section 80C, 80CCC, 80CCD(1): investments in EPF, PPF, LIC, ELSS, tuition fees, home loan principal (up to ₹1.5 lakh).
2. Section 80CCD(1B): additional ₹50,000 deduction for self-contribution to NPS.
3. Section 80D: medical insurance premiums for self, family, parents.
4. Section 10(13A) — HRA: House Rent Allowance exemption.
5. Section 10(5) — LTA: Leave Travel Allowance.
6. Section 24(b) — home loan interest: interest paid on self-occupied housing loan (up to ₹2 lakh).
7. Section 80E: interest paid on education loans.
8. Section 80G: donations to charitable trusts and relief funds.
9. Section 80TTA / 80TTB: deduction on savings account interest.
10. Chapter VI-A allowances: professional tax, children’s education allowance, helper allowance.

Deductions you KEEP under new regime

The new regime is not entirely devoid of deductions. You can still claim:

1. Standard deduction: ₹75,000 against salary income.
2. Section 80CCD(2): employer’s contribution to NPS (up to 14% of basic salary for Government employees, 10% for private sector).
3. Section 80CCH: contribution to the Agniveer Corpus Fund.
4. Section 24(b) for let-out property: you can claim interest on a home loan for a property you have rented out. However, you can only deduct this up to the amount of rental income received (you cannot declare a “loss from house property” to offset salary income like you can in the old regime).
5. Section 10(14): transport allowance for specially-abled persons, conveyance allowance for official duties.

The breakeven analysis — when does old beat new?

With the Budget 2025 rate cuts, the new regime is extraordinarily powerful. For the old regime to be mathematically beneficial, you need a highly specific “deduction profile.”

Rules of thumb for FY 2025-26:

• If gross income is under ₹12.75 lakh → new regime wins by default (zero tax).
• If gross income is ₹15 lakh → you need over ₹4.25 lakh in eligible deductions (e.g., 80C + HRA + 80D) for the old regime to win.
• If gross income is ₹25 lakh → you need over ₹4.5 lakh in eligible deductions for the old regime to win.

Unless you are maxing out 80C (₹1.5L), paying substantial rent to claim HRA (₹1.5L+), and paying heavy interest on a home loan, the old regime will likely result in a higher tax outgo.

Worked examples (4 income levels)

Example 1: junior executive (gross salary: ₹8,00,000)

Assume ₹1,50,000 invested in PPF (80C).

• New regime:
  • Gross salary: ₹8,00,000
  • Standard deduction: ₹75,000
  • Taxable income: ₹7,25,000
  • Tax computed: ₹16,250
  • Section 87A rebate: −₹16,250
  • Net tax: ₹0 (new regime wins)
• Old regime:
  • Gross salary: ₹8,00,000
  • Standard deduction: ₹50,000
  • 80C deduction: ₹1,50,000
  • Taxable income: ₹6,00,000
  • Tax computed: ₹32,500 + 4% cess = ₹33,800

Example 2: mid-level manager (gross salary: ₹15,00,000)

Profile: ₹1.5L (80C) + ₹50K (NPS 80CCD(1B)) + ₹25K (80D) + ₹2.4L (HRA). Total deductions = ₹4,65,000.

• New regime:
  • Gross salary: ₹15,00,000
  • Standard deduction: ₹75,000
  • Taxable income: ₹14,25,000
  • Tax computed (slabs): 0 (0–4L) + ₹20,000 (4–8L @ 5%) + ₹40,000 (8–12L @ 10%) + ₹33,750 (12–14.25L @ 15%) = ₹93,750
  • Plus 4% cess: ₹3,750
  • Net tax: ₹97,500 (new regime wins)
• Old regime:
  • Gross salary: ₹15,00,000
  • Standard deduction: ₹50,000
  • Total deductions: ₹4,65,000
  • Taxable income: ₹9,85,000
  • Tax computed (slabs): ₹12,500 (2.5–5L @ 5%) + ₹97,000 (5–9.85L @ 20%) = ₹1,09,500
  • Plus 4% cess: ₹4,380
  • Net tax: ₹1,13,880

Example 3: tech lead (gross salary: ₹25,00,000)

Profile: maxed deductions. ₹1.5L (80C) + ₹50K (NPS) + ₹50K (80D) + ₹3.6L (HRA) + ₹2L (home loan interest). Total deductions = ₹8,10,000.

• New regime:
  • Taxable income (₹25L − ₹75K std ded): ₹24,25,000
  • Tax computed (full slabs through 24L = ₹3,00,000) + 30% × ₹25,000 (₹7,500) = ₹3,07,500
  • Plus 4% cess: ₹12,300
  • Net tax: ₹3,19,800
• Old regime:
  • Taxable income (₹25L − ₹50K std ded − ₹8.1L deductions): ₹16,40,000
  • Tax computed (slabs): ₹1,12,500 (up to 10L) + 30% × ₹6.4L (₹1,92,000) = ₹3,04,500
  • Plus 4% cess: ₹12,180
  • Net tax: ₹3,16,680 (old regime wins narrowly by ~₹3K)

Example 4: VP (gross salary: ₹50,00,000)

Profile: same maxed deductions of ₹8.1L as Example 3.

• New regime:
  • Taxable income (₹50L − ₹75K std ded): ₹49,25,000
  • Tax computed: ₹3,00,000 (up to 24L) + 30% × ₹25.25L (₹7,57,500) = ₹10,57,500
  • Plus 4% cess: ₹42,300
  • Net tax: ₹10,99,800
• Old regime:
  • Taxable income (₹50L − ₹50K − ₹8.1L deductions): ₹41,40,000
  • Tax computed: ₹1,12,500 (up to 10L) + 30% × ₹31.4L (₹9,42,000) = ₹10,54,500
  • Plus 4% cess: ₹42,180
  • Net tax: ₹10,96,680 (old regime wins by ~₹3K)

How to switch — Form 10-IEA + 12BB mechanics

Because the new regime is the default under Section 115BAC, doing nothing means your taxes will automatically be calculated using the new slabs.

1. Form 12BB (employer declaration): At the beginning of the financial year (April/May), your employer asks you to declare your intended tax regime for the year via Form 12BB or their HR portal. Your employer uses this choice strictly to calculate the TDS to deduct from your monthly paycheck.

Note: the choice you make with your employer is not legally binding. You can change your mind at the end of the year when you actually file your return. Ensure your TDS aligns with the rules in the TDS overview.

2. Form 10-IEA (filing declaration): If the old regime is better for you, formally opt out of the default new regime by submitting Form 10-IEA on the Income Tax e-filing portal before filing your ITR (and strictly before the Section 139(1) due date). If you file your ITR without submitting Form 10-IEA, the system forces you into the new regime.

For execution support, see the ITR Filing service.

Business income — the lock-in rule

The flexibility to switch between the two regimes every year is restricted to individuals with income from salary, house property, and other sources.

If your ITR includes income from business or profession (which includes freelancing, consulting, or trading in F&O):

• You can opt out of the new regime and choose the old regime by filing Form 10-IEA.
• However, if you ever decide to switch back to the new regime in a future year, you are locked in permanently. You will never be allowed to opt for the old regime again for the rest of your life (unless you cease to have business income entirely).

Practical decision framework — 5-step checklist

1. Is your gross income ≤ ₹12.75 lakh? Choose the new regime. It is mathematically impossible for the old regime to be better.
2. Do you have an active home loan? If you are not paying at least ₹1.5L to ₹2L in housing loan interest, the new regime is almost certainly better.
3. Are you renting? If you live in your own house and cannot claim HRA, the new regime is generally superior.
4. Are you forcing investments? Don’t lock ₹1.5 lakh into an illiquid 80C product (5-year FD or ULIP) just to save tax in the old regime, if the new regime gives you similar tax output with higher in-hand liquidity.
5. Compute before you commit: use the e-filing portal’s tax calculator or consult a professional to run your exact numbers.
