Income Tax Calculator

Since the new regime arrived, the question is no longer just how much tax you owe but which set of rules to owe it under. The answer depends entirely on your deductions: without them the new regime's wider slabs and larger standard deduction almost always win, and with enough of them the old regime can still be cheaper.

This works out both at once so you can see the gap rather than guess at it. Enter your gross income for the new regime figure, then add whatever deductions you actually claim — 80C, health insurance, HRA, home loan interest — and watch whether the old regime overtakes it.

The calculation includes the parts people forget. The standard deduction differs between regimes. The section 87A rebate can remove the tax entirely below a threshold, and in the new regime it tapers through marginal relief rather than cutting off at a cliff. Surcharge applies above fifty lakh, also with marginal relief. And four per cent cess is added at the end of all of it.

It is an estimate for a resident individual under sixty, on salary and ordinary income. Capital gains taxed at their own rates and relief under section 89 are not modelled, and the rates are for a specific financial year, which is stated on screen rather than left implied.
