ⓘ About this tool 🔄 Last updated 1 Sep 2026 ✓ Reviewed by TopToolAI Team

Estimate your annual income tax liability in India under the New Tax Regime slabs, with a full slab-by-slab breakdown showing exactly how much tax applies at each level. A salary of ₹10 lakh a year is taxed slab by slab rather than at one flat rate — income up to ₹3 lakh is tax-free, and only the portion above each threshold is taxed at that slab's rate.

India Income Tax Calculator FAQs

Old regime or new regime?
This uses the New Tax Regime slabs. The Old Regime has different slabs and allows more deductions — compare both with a tax advisor to see which is better for you.
Is a rebate applied?
Yes. Under the new regime, income up to ₹12,00,000 pays no tax because of the section 87A rebate, and marginal relief applies just above that level.
Does this include cess?
Yes. The 4% Health and Education Cess is added to the tax in the result. Surcharge on incomes above ₹50 lakh is not included.
Which regime allows deductions like 80C and HRA?
The Old Regime allows most common deductions and exemptions; the New Regime offers lower slab rates but removes most of these deductions.
