⌖ §I / Formula
The math,
in the open.
Indian income tax for individuals runs on two parallel regimes for FY 2025-26. The New Regime, default from AY 2024-25 onwards, runs on broader slabs with a higher standard deduction (₹75,000) and a generous §87A rebate (up to ₹60,000 of tax for taxable income ≤ ₹12L), but disallows most chapter-VI-A deductions like 80C, 80D and HRA. The Old Regime keeps the historical slabs (basic exemption ₹2.5L / ₹3L / ₹5L depending on age), allows the full deduction stack, and gives a smaller §87A rebate (up to ₹12,500 for taxable income ≤ ₹5L).
Total tax = Slab tax − §87A rebate
+ Surcharge × (10% / 15% / 25% / 37%)
+ 4% Health & Education Cess
Surcharge kicks in at the ₹50L / ₹1Cr / ₹2Cr / ₹5Cr thresholds. The New Regime caps the surcharge at 25% even above ₹5Cr; the Old Regime goes up to 37%. Marginal relief applies when an additional rupee of income would push tax up by more than the rupee itself — CBDT does the arithmetic automatically in the return filing software, and we don't model it here.
Edge cases the calculator does not currently handle: AMT under §115JC, capital gains taxed at special rates (LTCG/STCG, 112A, 111A), agricultural income aggregation, foreign tax credit. For anything beyond the slab + cess + surcharge structure, book a consultation.
