Formula
Tax = slab tax − §87A rebate + surcharge + 4% cess · Taxable = Gross income − deductions
Calculation method
Computes tax under both the Old and New regimes for a selectable assessment year (AY 2024-25, 2025-26, 2026-27 — default AY 2026-27 / FY 2025-26), each a versioned ruleset. Slab tax is applied to taxable income, the Section 87A rebate and marginal relief are applied, then surcharge (with marginal relief) and a 4% Health & Education Cess. Total income (§288A) and total tax (§288B) are rounded to the nearest ₹10, matching the ITD portal. Both regimes are compared to recommend the cheaper one.
