No, income is not equal to salary. Your salary comprises components such as basic pay, variable pay, allowances, and perquisites. These components are either taxable or fully/ partially exempt. Income tax is calculated based on the taxability of each component and its exemptions and deductions. The gross salary minus your tax payable is the income from salaries. Moreover, for the purpose of taxation net taxable salary is not the total income. Total income includes income from salaries, capital gains, rental income, business or profession income, or income from other sources
