How to use this calculator
- Enter the amount added to income and any other income of the year.
- Choose the type of addition to match your situation.
- Read the tax on the unexplained income, the surcharge, the cess and the total in the result.
No deduction or set-off is allowed against the income; penalty provisions are separate.
The result is an estimate for the figures you enter. It is not a filed return, a certificate or professional advice. Rates, thresholds and section numbers change with each Finance Act, and the Income-tax Act, 2025 applies from 1 April 2026 with new section and form numbers.
