How to use this calculator
- Enter the amounts invested or paid for each deduction and your age category.
- Choose your age group and the deductions that apply to you to match your situation.
- Read the claimed amount, the unused limit and the estimated tax effect in the result.
Most Chapter VI-A deductions are available only under the old regime; check each limit and eligibility condition.
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.
