How This Calculator Works

This calculator estimates old and new regime tax for AY 2026-27 using slab rates, standard deduction, selected deductions, Section 87A rebate, surcharge, and 4% health and education cess. It is designed for quick planning, not tax filing.

Example Scenario

For a salaried person earning Rs. 15,00,000 with Rs. 1,50,000 under 80C and Rs. 25,000 under 80D, this calculator compares the lower-slab new regime against the deduction-heavy old regime and shows which estimate is lower.

Educational estimate only: Tax rules, eligibility, surcharge, marginal relief, and deduction treatment can vary by facts and future changes. Verify with official guidance or a qualified tax professional.
