How to read this income tax calculator fy 2025–26

Choose the income basis carefully. Already-taxable income has eligible deductions applied before entry; the salary option subtracts only the modeled standard deduction. This tool covers one specified year and regime, not all filing circumstances.

Worked example

For FY 2025–26, eligible resident ordinary taxable income of ₹12,00,000 gives ₹0 tax after rebate. ₹12,10,000 gives ₹10,400 including cess after marginal relief. Salary of ₹12,75,000 gives ₹12,00,000 taxable after the ₹75,000 standard deduction.

Method and assumptions

Apply the declared new-regime slabs to rounded taxable income, then the eligible rebate or marginal relief and 4% cess. Final tax rounds to the nearest ₹10. Special-rate income and surcharge cases are unsupported.

Reviewed 12 September 2026. Supports the new regime for FY 2025–26 only. Choose taxable income if you have already deducted eligible amounts; no further deduction is applied. Salary mode deducts the lower of ₹75,000 and the salary entered, and assumes no other income or deductions. Old-regime, non-resident, capital-gain, lottery, crypto, other special-rate and surcharge cases are unsupported.

Slabs: nil to ₹4 lakh; then 5%, 10%, 15%, 20% and 25% in successive ₹4 lakh bands up to ₹24 lakh; 30% above that. Eligible resident income up to ₹12 lakh receives a rebate up to ₹60,000. Marginal relief limits tax just above that threshold; 4% cess is then added. Taxable income and final tax are rounded to the nearest ₹10. TDS, advance tax, late fees and interest are not included.

Example: ₹12 lakh taxable income gives ₹0 tax. ₹12.10 lakh taxable income gives ₹10,000 after relief, plus ₹400 cess. ₹12.75 lakh salary gives ₹12 lakh taxable income and ₹0 tax.
