What is the Indian Income Tax Calculator (FY 2024-25 & FY 2025-26)?
This tool calculates Indian income tax liability under both the New Tax Regime (Section 115BAC) and Old Tax Regime for Financial Year 2025-26, highlighting the optimal tax choice.
Statutory Slab Application and Section 87A Rebate Mechanics
The New Tax Regime (default u/s 115BAC) offers lower slab rates and an enhanced Standard Deduction of ₹75,000 for FY 2025-26, plus full Section 87A tax rebate up to ₹7,00,000 (effective zero tax up to ₹7.75 Lakhs for salaried employees). The Old Regime retains higher slab rates but permits deductions under Chapter VI-A (80C, 80D, HRA u/s 10(13A), 24b home loan interest). Both add 4% Health and Education Cess to the base tax.
