For a Rs 12 lakh salary with standard deductions only, the new regime gives zero tax (87A rebate). But add home loan interest (Rs 2L), full 80C (Rs 1.5L), NPS (Rs 50K) and HRA — old regime saves Rs 40,000–80,000 more. Always calculate both before filing.

New regime slabs (FY 2025-26)
The new regime has six slabs: nil up to Rs 3L, 5% from Rs 3–7L, 10% from Rs 7–10L, 15% from Rs 10–12L, 20% from Rs 12–15L, and 30% above Rs 15L. The standard deduction is Rs 75,000. Due to the Section 87A rebate, effectively zero tax is payable on income up to Rs 12.75 lakh.
Old regime slabs (FY 2025-26)
The old regime has three slabs: nil up to Rs 2.5L, 5% from Rs 2.5–5L, 20% from Rs 5–10L, and 30% above Rs 10L. Standard deduction is Rs 50,000. Section 87A gives full rebate on income up to Rs 5L. The key advantage is the wide array of deductions — 80C, 80D, HRA, home loan interest, NPS — that can significantly reduce taxable income.
How to decide between old and new regime
The breakeven point is approximately Rs 3.75 lakh in deductions. If your total eligible deductions (beyond the standard deduction) exceed Rs 3.75 lakh, the old regime saves more tax. Below that threshold, the new regime's lower slabs win. For most salaried employees without home loans, the new regime is simpler and cheaper. For home loan borrowers with full 80C utilisation, the old regime often wins above Rs 10L income.
