How this calculator works
Both regimes are computed with the same four steps: subtract the standard deduction (and, for the old regime, any Chapter VI-A deductions you enter) from your gross income to get taxable income; apply the progressive slab rates to get tax before rebate; apply the Section 87A rebate if you qualify; then add surcharge (for high incomes) and 4% Health & Education Cess.

This calculator covers salaried and pensioner resident individuals with income from salary. It does not cover capital gains (taxed separately at special rates), business income, HRA exemption calculation, or non-resident taxation. For those situations, use this as a starting estimate and confirm with a chartered accountant or incometax.gov.in.
