Computation of Income
Computation of Income is the process of calculating a taxpayer’s total taxable income in accordance with the provisions of the Income Tax Act. It involves identifying income earned under different heads—such as salary, house property, business or profession, capital gains, and income from other sources—and then applying the applicable exemptions, deductions, and set-offs as prescribed by law.

Computation of Income Under Income Tax Act, 1961
The computation of income under the Income Tax Act, 1961 is the structured process of determining a taxpayer’s total taxable income in accordance with statutory provisions. It involves identifying income earned during a financial year and classifying it under the prescribed heads of income such as salary, house property, business or profession, capital gains, and income from other sources.
After calculating income under each head, eligible exemptions, deductions under Chapter VI-A, and applicable set-off or carry forward of losses are applied to arrive at the total income. Accurate computation of income is essential to determine the correct tax liability, ensure compliant income tax return filing, and avoid penalties or notices from tax authorities.
Components of Income Tax Computation
- Income from Salary: Includes basic salary, allowances, bonuses, perquisites, and taxable benefits received from an employer.
- Income from House Property: Covers rental income from let-out properties and deemed income, after allowable deductions such as interest on housing loans.
- Income from Business or Profession: Net profits earned from business or professional activities after deducting permissible expenses and depreciation.
