Calculate income tax under the new regime (FY 2025-26 slabs, ₹75k standard deduction, ₹60k rebate) and old regime side-by-side to see which is better for you.
Based on the inputs, the new regime saves you ₹97,500. Note: surcharge for incomes above ₹50L is not included here.
This Income Tax Calculator computes your tax liability under both the Old Regime (with deductions) and the New Regime (default from FY 2023-24, with lower slabs and no deductions) so you can pick the optimal one. It applies the current slabs, Section 87A rebate (₹25,000 up to ₹7 L income under new regime; ₹12,500 up to ₹5 L under old), surcharge (10/15/25/37%) and 4% Health & Education Cess.
The new tax regime was made the default from Budget 2023, with FY 25-26 slabs providing zero tax up to ₹12 lakh income (after ₹75k standard deduction) via the enhanced 87A rebate. Use this calculator alongside HRA, Section 80C and NPS calculators to build a full tax-optimisation stack for salaried, professional and business income.
