Understand your tax.
Choose with clarity.
A few details. Both regimes. One clear comparison — with the calculation explained.
Simple inputs. Transparent calculation.
1. Enter gross income
Use salary or regular pension before standard deduction. Add family pension and taxable interest separately.
2. Add claims you are eligible for
Common caps, age-based benefits and regime restrictions are applied automatically. Do not count the same payment under two claims.
3. Compare the actual tax
See rebate, marginal relief, surcharge and 4% cess separately. The highlighted regime has the lower estimated annual tax for these inputs.
What this edition covers
Resident individuals: salary, taxable regular/family pension, eligible bank interest and ordinary taxable income. Excludes capital gains, dividends, business, foreign/agricultural income, crypto/gaming, losses, AMT, treaty relief, arrears relief and interest/fees. A regime comparison is not an election in your filed return.
