Two Regimes, Two Slab Structures
For FY 2025-26 (AY 2026-27), the New Tax Regime (default) taxes income at 0% up to ₹4 Lakh, then 5%, 10%, 15%, 20%, 25%, and 30% in ₹4 Lakh steps up to ₹24 Lakh and beyond, with a flat ₹75,000 standard deduction for salaried taxpayers. The Old Tax Regime uses wider bands (Nil to ₹2.5 Lakh, 5% to ₹5 Lakh, 20% to ₹10 Lakh, 30% above) with a ₹50,000 standard deduction, but allows exemptions like HRA and deductions under 80C, 80D, and 24(b) that the New Regime does not.
