SIP Calculator EMI CalculatorAbout this income tax calculator
This calculator computes your Indian income tax for FY 2025-26 (AY 2026-27) under both the new regime (section 115BAC) and the old regime. It aggregates income across all heads — salary, house property, presumptive business, other sources and capital gains — applies the eligible deductions, and works out income tax, the section 87A rebate, surcharge (with marginal relief and the 15% cap on 111A/112A/dividend income), 4% health & education cess, foreign tax credit and finally your balance payable or refund.
It runs entirely in your browser using JavaScript — no figures are ever sent to a server. Switch the regime toggle at the top to compare; old-regime-only fields (HRA and Chapter VI-A deductions) appear automatically when you pick the old regime.
Which ITR form should you file?
Salary-only taxpayers usually file ITR-1; those with capital gains, foreign income or more than one house property file ITR-2; presumptive business income uses ITR-4. Not sure? Use our Which ITR form applies to me guide.

Frequently asked questions
Is my data stored anywhere?
No. Every calculation happens in your browser. Nothing you type is transmitted to or saved on any server.
How is the section 87A rebate applied?
Under the new regime, if your total income is up to ₹12,00,000, a rebate up to ₹60,000 wipes out tax on normal-slab and 111A income (special-rate 112A LTCG is not eligible). Under the old regime the limit is ₹5,00,000 with a rebate up to ₹12,500.
Does it handle surcharge and marginal relief?
Yes. Surcharge tiers of 10%/15%/25%/37% apply above ₹50L/₹1Cr/₹2Cr/₹5Cr (capped at 25% in the new regime, and 15% on 111A/112A/dividend income), and marginal relief is applied at each threshold.
