What Are the Different Types of Income?
In India, every individual is required to pay income-tax on income earned or received, irrespective of their residential status, whether resident or non-resident. To ensure uniform assessment and taxation, the Income Tax Department classifies income into five major heads, each covering specific sources of earnings.
Income from House Property: This category includes income earned from renting out residential or commercial properties. Any rental income received by a property owner is taxable under this head.
Income from Salary: Income earned through employment, such as salaries, wages, pensions, bonuses, and allowances, is taxed under the head of salary income. Tax liability arises from income received from an employer.
Income from Business or Profession: This head applies to income earned by self-employed individuals, freelancers, business owners, contractors, and professionals such as chartered accountants, doctors, lawyers, life insurance agents, and private tutors. Profits derived from these activities are taxable as business or professional income.
Income from Capital Gains: Income generated from the sale or transfer of capital assets, including shares, mutual funds, bonds, or real estate, is taxable under capital gains. These gains are further classified into short-term and long-term capital gains.
Income from Other Sources: Any income that does not fall under the above categories is taxed as income from other sources. This includes interest earned on savings accounts and fixed deposits, dividends, lottery winnings, and other miscellaneous income.
