The Power of Choice: An Introduction to India's Two Tax Systems
One of the most significant developments in Indian personal finance has been the introduction of an optional new tax regime in 2020. This provides taxpayers with a choice between two distinct methods for calculating income tax liability.
The Old Tax Regime: Traditional system with higher tax rates but comprehensive deductions and exemptions (over 70 available). Incentivizes savings through instruments like HRA, LTA, Section 80C, and 80D.
The New Tax Regime (Section 115BAC): Simplified system with lower tax rates but minimal deductions. Designed for individuals who prefer straightforward calculation without extensive tax-saving investments.
From AY 2024-25 onwards, the New Tax Regime is the default option. The slabs below are the new-regime slabs introduced by the Finance Act, 2025, which apply for FY 2025-26 and continue for FY 2026-27.
Tax Slabs Comparison for FY 2025-26 / FY 2026-27
| Income Slab (₹) | Old Regime Rate | New Regime Rate |
|-----------------|-----------------|-----------------|
| Up to 2,50,000 | Nil | Nil |
| 2,50,001 to 4,00,000 | 5% | Nil |
| 4,00,001 to 5,00,000 | 5% | 5% |
| 5,00,001 to 8,00,000 | 20% | 5% |
| 8,00,001 to 10,00,000 | 20% | 10% |
| 10,00,001 to 12,00,000 | 30% | 10% |
| 12,00,001 to 16,00,000 | 30% | 15% |
| 16,00,001 to 20,00,000 | 30% | 20% |
| 20,00,001 to 24,00,000 | 30% | 25% |
| Above 24,00,000 | 30% | 30% |
Health and Education Cess of 4% applies on the tax in both regimes. Old-regime basic exemption is ₹3 lakh for senior citizens (60–80) and ₹5 lakh for super senior citizens (80+).
Tax Rebates (Section 87A):
- Old Regime: Up to ₹12,500 on total income up to ₹5,00,000
- New Regime: Up to ₹60,000 on total income up to ₹12,00,000 — so a salaried person earning up to ₹12.75 lakh (after the ₹75,000 standard deduction) pays no income tax. Marginal relief applies to income slightly above ₹12 lakh, so the tax can never exceed the amount by which income crosses ₹12 lakh.
Key Deductions Lost in New Regime:
- HRA exemption
- LTA exemption
- Section 80C deductions (₹1.5 lakh)
- Section 80D health insurance deductions
- Home loan interest deduction
- Professional tax deduction
Benefits Still Available in New Regime:
- Higher Standard Deduction (₹75,000 vs ₹50,000)
- Employer's NPS contribution (Section 80CCD(2))
- Family pension deduction
Real-Life Scenarios:
Scenario 1: Ajay - The Renter and Investor
- Gross Salary: ₹13,00,000
- HRA exemption: ₹1,20,000
- Section 80C+80D: ₹1,80,000
Tax comparison (FY 2025-26 rates, including 4% cess):
- Old Regime: ₹1,06,600 (taxable income ₹9,50,000 after HRA, ₹50,000 standard deduction and 80C/80D)
- New Regime: ₹26,000 (taxable income ₹12,25,000 after the ₹75,000 standard deduction; slab tax of ₹63,750 is capped by marginal relief at ₹25,000, plus cess)
- Savings with New Regime: ₹80,600
Scenario 2: Sunita - The New Earner
- Gross Salary: ₹9,00,000
- Only EPF deduction: ₹40,000
Tax comparison (FY 2025-26 rates, including 4% cess):
- Old Regime: ₹77,480 (taxable income ₹8,10,000 after ₹50,000 standard deduction and EPF)
- New Regime: ₹0 (taxable income ₹8,25,000 is within the ₹12 lakh rebate limit)
- Savings with New Regime: ₹77,480
Decision Framework:
Calculate your total eligible deductions. If they exceed the "break-even point," choose the old regime. If lower, the new regime is better.
