Income Tax Calculator

India's income tax system operates across multiple slabs, different rates for different taxpayer categories, and a choice between two distinct regimes — making accurate computation genuinely complex without the right tool. This free income tax calculator covers every major taxpayer category: domestic companies, foreign companies, Limited Liability Partnerships (LLPs), and individuals — including resident and non-resident individuals — under both the New Tax Regime and the Old Tax Regime for FY 2025-26 (Assessment Year 2026-27).

Under the New Regime (Budget 2025), individual tax slabs start at nil for income up to ₹4 lakh and rise to 30% for income above ₹24 lakh. The calculator automatically applies the standard deduction of ₹75,000 for salaried individuals, the Section 87A rebate — which makes income up to ₹12 lakh effectively tax-free under the new regime — and the 4% Health & Education Cess on the final tax liability.

For companies, the calculator handles four rate structures: the normal domestic company rate (25% for turnover ≤ ₹400 crore, 30% above), the concessional Section 115BAA rate (22%), the new manufacturing company rate under Section 115BAB (15%), and the foreign company flat rate of 40%. Each computation includes the applicable surcharge — which varies between 7% and 12% for domestic companies — and the 4% cess. The calculator also flags potential Minimum Alternate Tax (MAT) and Alternate Minimum Tax (AMT) liability when regular tax falls below the statutory minimum.

LLP and partnership firm tax is calculated at a flat 30% rate with applicable surcharge and cess. Every computation shows a slab-wise breakdown — not just a final number — so you can verify exactly how each portion of income is taxed.
