Quick Overview
The Indian income tax system now offers two parallel regimes: the Old (Traditional) Tax Regime and the New (Simplified) Tax Regime. Both arrive at the same gross tax liability table — you pay tax only on income above the basic exemption limit — but they differ dramatically in the deductions and exemptions you are allowed to claim. The right choice can mean a difference of ₹30,000 to ₹80,000 in annual tax outgo for a mid-income salaried professional.
Since the Union Budget 2023, the New Regime has been the default option. For FY 2026-27, the Finance Minister further sweetened it by increasing the standard deduction to ₹75,000 and expanding the 87A rebate ceiling to ₹12 lakh of taxable income, effectively making tax zero for crores of salaried Indians. But does that mean the Old Regime is dead? Not at all — for high-deduction taxpayers, it remains the smarter choice.
New Regime Tax Slabs for FY 2026-27
| Income Slab | Tax Rate |
|---|---|
| Up to ₹4,00,000 | Nil |
| ₹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% |
Key benefit: The Section 87A rebate in the New Regime provides full tax relief for net taxable incomes up to ₹12 lakh. After applying the ₹75,000 standard deduction, a salaried person earning up to ₹12.75 lakh gross salary pays ZERO income tax.
Old Regime Tax Slabs for FY 2026-27
| Income Slab | Tax Rate |
|---|---|
| Up to ₹2,50,000 | Nil |
| ₹2,50,001 – ₹5,00,000 | 5% |
| ₹5,00,001 – ₹10,00,000 | 20% |
| Above ₹10,00,000 | 30% |
The Old Regime allows a wide array of deductions and exemptions: Section 80C (up to ₹1.5 lakh for PPF, ELSS, life insurance, EPF, home loan principal), Section 80D (health insurance premiums), HRA exemption, Leave Travel Allowance, Section 24(b) home loan interest (up to ₹2 lakh), NPS under Section 80CCD(1B) (additional ₹50,000), and more. The standard deduction under the Old Regime is ₹50,000.

The Breakeven Deduction Threshold
The critical question is: how much in deductions do you need before the Old Regime becomes better? The answer depends on your gross income. If your total claimable deductions exceed the breakeven threshold, the Old Regime saves more tax:
| Gross Salary (₹) | Breakeven Deductions Needed for Old Regime |
|---|---|
| 7,50,000 | Old Regime never wins (New Regime zero tax via 87A) |
| 10,00,000 | ~₹2,60,000 in total deductions |
| 12,00,000 | ~₹3,00,000 in total deductions |
| 15,00,000 | ~₹4,25,000 in total deductions |
| 20,00,000 | ~₹4,25,000 in total deductions |
| 25,00,000 | ~₹4,75,000 in total deductions |
Example: At ₹15L salary, if you have ₹1,50,000 (80C) + ₹50,000 (80D) + ₹2,00,000 (Home Loan Interest 24b) + ₹50,000 (NPS 80CCD(1B)) = ₹4,50,000 in deductions → Old Regime is better. If you cannot reach ₹4,25,000 in deductions, pick the New Regime.
Who Should Choose Which Regime?
Choose the New Tax Regime if:
- Your gross salary is ₹12.75 lakh or below (you pay zero tax under New Regime).
- You live in your own home or with parents (no HRA or home loan interest deduction).
- You don't have significant Section 80C investments beyond mandatory EPF.
- You prefer simplicity over tax-filing complexity.
- You are a first-time taxpayer with minimal investment portfolio.
- Your income comes primarily from business or freelancing (simpler compliance).
Choose the Old Tax Regime if:
- You pay significant rent in a metro city and claim HRA exemption.
- You have an active home loan and claim ₹2 lakh interest deduction under Section 24(b).
- You consistently max out Section 80C (PPF, ELSS, LIC, EPF) at ₹1.5 lakh.
- You or your family pay health insurance premiums claimable under 80D.
- Your total deductions exceed the breakeven threshold for your income level.
- You are in a higher tax bracket (₹20L+ salary) with multiple deductions.
Understanding the Section 87A Rebate
Section 87A is a full tax rebate — not a deduction. If your net taxable income falls at or below the rebate threshold, the entire tax computed (up to ₹25,000) is waived off. Under the New Regime for FY 2026-27, the threshold is ₹12 lakh. This means a salaried person earning ₹12.75 lakh gross (after ₹75,000 standard deduction, net taxable = ₹12 lakh) pays absolutely zero income tax.
The 87A rebate is not available on special rate income such as Short-Term Capital Gains (STCG) under Section 111A (taxed at 20%) and Long-Term Capital Gains (LTCG) under Section 112A (taxed at 12.5%). These are taxed at flat rates regardless of rebate eligibility.
