New Tax
Regime
2025-26.

Budget 2025 was a watershed moment for India's tax landscape. Finance Minister Nirmala Sitharaman announced three changes that fundamentally shifted the calculus between New and Old regimes:

1. Section 87A rebate enhanced to ₹60,000: Any individual with total taxable income up to ₹12 lakh now pays zero income tax under the New Regime. Combined with the ₹75,000 standard deduction, a salaried individual earning up to ₹12.75 lakh gross salary pays no income tax at all.

2. New tax slabs restructured: The ₹0–3 lakh slab (previously ₹0–2.5L) and the 5% slab now extends to ₹7 lakh (previously ₹5L). These revisions reduced the effective tax rate at almost every income level.

3. Standard deduction maintained at ₹75,000: First introduced at ₹50,000 in the New Regime in FY 2023-24 and raised to ₹75,000 in Budget 2024, this deduction is now the primary benefit available in the new regime.

The combined impact: at ₹12 lakh income, the Old Regime would generate a tax of approximately ₹1,17,000 (pre-deductions). The New Regime generates zero. Even after accounting for 80C deductions of ₹1.5 lakh under Old Regime, the New Regime still produces lower or equal tax liability for most individuals below ₹12L.

The New Tax Regime is not a free lunch. It trades deductions for lower rates. Before switching, you must calculate whether the rate reduction saves more tax than the deductions you're giving up.

The biggest losses:

Section 80C (₹1.5 lakh): This is the most impactful deduction most salaried Indians claim — PPF contributions, ELSS mutual funds, life insurance premiums, home loan principal, children's tuition fees. In the Old Regime at the 30% slab, this single deduction saves ₹46,800 in tax (₹1.5L × 30% + 4% cess). In the New Regime — you get nothing for these investments.

HRA Exemption: Salaried individuals paying rent in metros can exempt up to 50% of basic salary. For someone with ₹60,000 basic + HRA + paying ₹25,000 rent in Delhi, this exemption can be ₹2–3 lakhs annually. Gone entirely in the New Regime.

Section 24(b) Home Loan Interest (₹2 lakh): If you have a home loan on a self-occupied property, you can deduct up to ₹2 lakh in interest per year under Old Regime. At the 30% slab, this saves ₹62,400 annually. The New Regime offers no such relief.

Section 80D Health Insurance (₹25,000–₹75,000): Health insurance premiums for self, spouse, children, and parents are fully deductible. With parents above 60, the combined limit reaches ₹75,000.

The math: If your total claimable deductions under Old Regime (80C + HRA + 80D + 24(b) + NPS + others) exceed approximately ₹3.25 lakhs at ₹10L income or ₹4.5L at ₹15L income — Old Regime saves more tax. Below that threshold, New Regime wins.

Here is the definitive decision framework:

CHOOSE NEW TAX REGIME if: — Your total deductions are below the break-even threshold for your income level — You're a young professional early in your career with few investments — You don't pay rent (no HRA benefit) or live in your own house without a home loan — You prefer simplicity — no tracking investments for tax purposes — Your income is below ₹12.75 lakh (effectively zero tax) — You don't have dependent parents needing health insurance (80D)

CHOOSE OLD TAX REGIME if: — You have a home loan on a self-occupied property (₹2L 80C + ₹2L 24(b) = ₹4L deductions alone) — You pay high rent in a metro city and receive significant HRA from employer — You maximise 80C (₹1.5L) + 80D (₹75K) + NPS 80CCD(1B) (₹50K) = ₹2.75L+ in deductions — You're above the 30% slab and have aggressive tax planning in place — You have parents above 60 with medical expenses (80D up to ₹50K for parents)

THE BREAK-EVEN DEDUCTION THRESHOLD (approximate): ₹8L income → need ₹2.25L deductions for Old Regime to win ₹10L income → need ₹3.25L deductions ₹12L income → need ₹4.25L deductions (nearly impossible — New Regime wins) ₹15L income → need ₹3.75L deductions ₹20L income → need ₹4.5L deductions ₹30L income → need ₹5.75L deductions

Reality check: the average salaried Indian claims ₹1.5L (80C) + ₹25K (80D) + some HRA. Unless you have a home loan or maximise every deduction, the New Regime is typically better below ₹20L income.

Section 87A is widely misunderstood. Let's clarify precisely how it works under the New Regime for FY 2025-26.

Step-by-step for a salaried individual earning ₹12,75,000 gross:

Step 1: Gross Salary = ₹12,75,000 Step 2: Less Standard Deduction = ₹75,000 Step 3: Net Taxable Income = ₹12,00,000

Step 4: Apply New Regime slabs to ₹12,00,000: ₹0 – ₹3L = Nil → ₹0 ₹3L – ₹7L = 5% → ₹20,000 ₹7L – ₹10L = 10% → ₹30,000 ₹10L – ₹12L = 15% → ₹30,000 Total tax before cess = ₹80,000

Step 5: Apply Section 87A rebate: Since taxable income ≤ ₹12L, rebate = ₹60,000 Tax after rebate = ₹80,000 – ₹60,000 = ₹20,000

Wait — the rebate only covers ₹60,000. Isn't there ₹20,000 still due?

This is the most common confusion. The government applied a marginal relief mechanism: since the rebate makes ₹12L income tax-free, incomes up to ₹12.75L (after standard deduction = ₹12L taxable) are effectively zero-tax. The marginal relief ensures you don't pay MORE tax at ₹12.75L than at ₹12L.

Important: once taxable income crosses ₹12L, the FULL tax liability applies (no partial rebate). The cliff at ₹12,00,001 is steep — always be aware of which side of the threshold you're on.

Here's the hidden gem of the New Tax Regime that most salaried Indians don't use: Section 80CCD(2) — employer's contribution to NPS.

Under both Old and New regimes, your employer's NPS contribution is deductible from your taxable income. The limit is: — Government employees: 14% of (Basic + DA) — Private sector employees: 10% of (Basic + DA)

Why this matters: this is a salary restructuring tool, not just a tax deduction. If your employer agrees to contribute 10% of your basic salary to NPS instead of paying it as taxable compensation, it reduces your taxable income — without costing you anything in take-home pay.

Example: Basic salary ₹8 lakh/year. Employer NPS contribution at 10% = ₹80,000. This ₹80,000 is: — Deducted from your taxable income under New Regime — Invested in NPS (growing at ~10–12% historically) — Eventually received at retirement with 60% fully tax-free lump sum

For someone in the 20% tax bracket, this saves ₹16,640 annually (₹80,000 × 20% × 1.04 cess). For 30% bracket, it saves ₹24,960 annually.

Action: Ask your HR/payroll team to restructure your CTC to include employer NPS contribution. This is 100% legal, SEBI-regulated, and works even in the New Regime. Combined with the standard deduction of ₹75,000, this is the most powerful tax optimisation available to salaried New Regime taxpayers.

Since FY 2023-24 (AY 2024-25), the New Tax Regime is the default. You don't need to do anything to stay in New Regime — you're already there unless you opt out.

TO SWITCH TO OLD REGIME (from New Regime):

For salaried employees WITHOUT business income: — At the time of filing ITR (before the due date, usually July 31) — Simply select "Old Regime" in your ITR form (ITR-1 or ITR-2) — No separate form required — You can switch back again next year

For individuals WITH business/professional income: — Must file Form 10-IEA before the ITR due date — This is a one-time switch — you cannot oscillate freely — Once you switch back to Old Regime, you can only switch to New Regime once in your lifetime

EMPLOYER TDS IMPLICATIONS: At the start of each financial year (April), your employer asks you to declare your tax regime choice. This determines how TDS is deducted from your salary monthly. If you don't declare, employer deducts TDS under New Regime (the default).

Key dates: — April 1: New financial year begins, declare regime to employer — July 31: ITR filing deadline (for most salaried) — final regime choice — March 31: Last date for any advance tax payments

Pro tip: Your employer TDS regime and your actual ITR filing regime can differ. If you choose Old Regime at ITR filing (after telling employer New Regime), you may get a tax refund — or face demand. Always align your employer declaration with your intended ITR filing.

Let's do the actual math. No hand-waving. Just numbers.

CASE 1: ₹10,00,000 gross salary Assumptions: 80C = ₹1.5L, 80D = ₹25K, HRA = ₹1L, no home loan Total Old Regime deductions: ₹50K std + ₹1.5L + ₹25K + ₹1L = ₹3.25L Old Regime taxable income: ₹6.75L → Tax = ₹52,500 × 1.04 = ₹54,600 New Regime taxable income: ₹9.25L (after ₹75K std deduction) → Tax = ₹52,500 × 1.04 = ₹54,600 VERDICT: Equal. Any additional deduction (NPS, extra 80D) tips Old Regime ahead.

CASE 2: ₹15,00,000 gross salary Assumptions: 80C = ₹1.5L, 80D = ₹50K, HRA = ₹1.5L, home loan interest = ₹1.5L Total Old Regime deductions: ₹50K + ₹1.5L + ₹50K + ₹1.5L + ₹1.5L = ₹5.5L Old Regime taxable income: ₹9.5L → Tax = ₹1,17,000 × 1.04 = ₹1,21,680 New Regime taxable income: ₹14.25L → Tax = ₹1,42,500 × 1.04 = ₹1,48,200 VERDICT: Old Regime saves ₹26,520. At ₹15L with full deductions, Old Regime wins.

CASE 3: ₹20,00,000 gross salary Assumptions: Same deductions as Case 2 (₹5.5L total) Old Regime taxable income: ₹14.5L → Tax = ₹2,62,500 × 1.04 = ₹2,73,000 New Regime taxable income: ₹19.25L → Tax = ₹2,77,500 × 1.04 = ₹2,88,600 VERDICT: Old Regime saves ₹15,600. Margin narrows significantly at higher income.

KEY INSIGHT: The higher your income, the less impactful fixed deductions (80C, 80D) become as a percentage of taxable income. At ₹50L+, New Regime's capped 25% surcharge (vs Old Regime's potential 37%) can make New Regime significantly better.
