New Tax Regime -- FY 2026-27 (AY 2027-28)
Every February, my Karol Bagh office fills with salaried employees asking which regime to choose. After analyzing 1,000+ returns, the answer depends on your deductions. The new tax regime (Section 115BAC) has been the default regime since FY 2023-24. It offers lower tax rates but fewer deductions and exemptions.

| Income Slab (₹) | Tax Rate |
|---|---|
| 0 - 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% |
- Standard deduction: ₹75,000 (salaried & pensioners)
- Rebate u/s 87A: Up to ₹60,000 (effective tax-free income up to ₹12 lakh for salaried)
- Surcharge: 10% above ₹50L, 15% above ₹1Cr, 25% above ₹2Cr
- Cess: 4% Health & Education Cess on tax + surcharge
• Gross income: ₹12,00,000
• Standard deduction: ₹75,000
• Taxable income: ₹11,25,000
• Tax: ₹4,00,001-8,00,000 @5% = ₹20,000 + ₹8,00,001-11,25,000 @10% = ₹32,500
• Total tax: ₹52,500
• After 87A rebate (₹52,500): ₹0
• Net tax = ZERO
Old Tax Regime -- FY 2026-27
The old regime allows all traditional deductions and exemptions. It benefits taxpayers who have significant investments under Section 80C, home loan interest, HRA, and other deductions. In my experience, if your total deductions exceed ₹3.75 lakh, the old regime saves you money.
| Income Slab (₹) | Tax Rate |
|---|---|
| 0 - 2,50,000 | Nil |
| 2,50,001 - 5,00,000 | 5% |
| 5,00,001 - 10,00,000 | 20% |
| Above 10,00,000 | 30% |
- Section 80C: Up to ₹1.5 lakh (PPF, ELSS, LIC, NPS, home loan principal)
- Section 80D: Up to ₹25,000 (₹50,000 for senior citizens) medical insurance
- HRA exemption: For salaried staying in rented accommodation
- Section 24(b): Up to ₹2 lakh home loan interest
- Standard deduction: ₹50,000

Tax Calculation Examples
Let me show you with real numbers -- these are the kinds of calculations I do every day for clients in my Delhi office:
Example 1: Salaried, ₹10 lakh income, minimal deductions

| After rebate | ₹0 | ₹60,000 |
Winner: New Regime -- saves ₹60,000 thanks to the 87A rebate.
Old Regime: Taxable = ₹18L - ₹50K - ₹5.55L = ₹11.95L → Tax = ₹1,73,500 + 4% cess = ₹1,80,440
New Regime: Taxable = ₹18L - ₹75K = ₹17.25L → Tax = ₹2,13,750 + 4% cess = ₹2,22,300
Old Regime saves ₹41,860!
