Income Tax Calculator India
FY 2024-25 new & old regime tax with surcharge, cess, 87A rebate and slab-wise breakdown.
About the Income Tax Calculator India
Income Tax Calculator India computes your liability under either the new (default) or old regime using the slab rates announced in the Union Budget 2024-25. The new regime applies slabs of 0% up to ₹3 lakh, 5% from ₹3–7 lakh, 10% from ₹7–10 lakh, 15% from ₹10–12 lakh, 20% from ₹12–15 lakh and 30% above, with a standard deduction of ₹75,000. The old regime keeps the familiar 0/5/20/30 slabs with a ₹50,000 standard deduction plus your Chapter VI-A deductions (80C, 80D, HRA etc.). Health & education cess of 4% is applied to the final tax, surcharge kicks in above ₹50 lakh and the 87A rebate zeroes out the bill for incomes up to ₹7 lakh new regime / ₹5 lakh old regime. Use this as a fast decision helper, not as a substitute for a CA.
