Frequently asked questions
How is income tax calculated in India?
Income is reduced by the standard deduction and other eligible deductions to get taxable income. Tax is then applied slab by slab under the chosen regime, a rebate under section 87A may apply, and 4% health and education cess is added to the tax payable.
Which regime should I choose — new or old?
The new regime offers wider slabs and a higher standard deduction but removes most exemptions. The old regime keeps deductions such as HRA, section 80C and 80D. Compare both using your own numbers before deciding.
Does this calculator include marginal relief and surcharge?
No. The result is indicative, using FY 2025-26 (AY 2026-27) rates, and excludes marginal relief, surcharge and most deductions, so your actual liability may differ.
