How to use this calculator
- Enter the income, the deductions and the regime for each scenario.
- Choose the regime for each scenario to match your situation.
- Read the tax for each scenario and the gap between the highest and lowest in the result.
The comparison depends entirely on the inputs; verify each scenario against your facts.
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.
