Income Tax Calculator

The new tax regime (the default) offers lower rates and a ₹60,000 §87A rebate that makes income up to ₹12 lakh tax-free, but allows almost no deductions. The old regime has higher rates but lets you claim deductions for investments, insurance, HRA and home loan interest, with a ₹12,500 rebate that makes income up to ₹5 lakh tax-free. Which is cheaper depends on how many deductions you claim. The calculator compares both side by side for the same income.

On incomes above ₹50 lakh a surcharge applies on top of the slab tax relative to total income — 10% to ₹1 crore, 15% to ₹2 crore, 25% to ₹5 crore and up to 37% above that (capped at 25% in the new regime). Marginal relief ensures that where income only slightly crosses a threshold, the surcharge never creates a sudden jump beyond the extra income. The calculator applies and displays both.

The calculator applies the standard deduction automatically in both regimes — ₹75,000 in the new regime and ₹50,000 in the old. Under the old regime you can additionally enter 80C, 80D, HRA and home-loan-interest deductions, which lower your taxable income before the slabs are applied. These fields only affect the old regime, matching actual rules.

Enter your annual gross salary (including allowances that are fully taxable) and the calculator returns the full pipeline: taxable income, slab-by-slab tax, §87A rebate, surcharge with marginal relief, 4% health and education cess and the final tax payable — for planning purposes only, not as a substitute for professional advice or official filing guidance.

It computes the full tax pipeline in one place — standard deduction, slab-by-slab tax, rebate, surcharge, marginal relief, cess and effective rate — for either regime, so you can compare both and plan your deductions before filing. Everything runs in your browser; no income data leaves your device.
