What are the different sources of Income for an Individual?

According to the regulations made under Section 14 of the Income Tax Act, 1961 an individual can only have a total of five sources of earning revenue at all points of time. These sources as fixed by the Income Tax Department of India are:

  • Income from salary
  • Income from capital gains
  • Income from house property 
  • Income from business 
  • Income from other sources 

Income from Salary:

The first head of the sources of income allowed is the income from salary. The Income Tax calculator can be used efficiently to calculate the entire amount for you. 

Every employee is provided with Form 16 by the employer which includes a TDS certificate. This TDS certificate can be used to calculate your income from salary. The process is as follows:

  1. Collect all your salary slips and Form 16 for the ongoing financial year. Look for all the stipends and allowances (basic salary, TA, DA, HRA, other allowances) provided to you in your salary slips and Form 16 and add them together. Also, add your bonus to the final amount.
  2. The total amount after the summation of all these values will be your gross income.
  3. Deduct HRA exemption and transport allowance from your gross income amount.
  4. The resulting amount will give you your net income.

Income from House Property:

The second head of the sources of income allowed is income from house property. This is the computation of earnings of an individual from the rental income if he owns a land and house property. An individual will calculate his income from the property, where he only possesses the ownership of single property and that too is self-occupied.

To calculate the Gross Annual Value (GAV) for your rented house :

  1. Find out the Fair Market value (FMV) and the valuation estimated by the Municipal Corporation, and then choose the amount with a higher value. This will be the expected rent for your property.
  2. Compare the above-mentioned expected rent with the actual rent you receive. This will give you the gross annual value for your property.
  3. The net annual value for the property can be computed by deducting the already paid taxes for the property from the gross annual value.

Explain Income from Capital Gains:

A property that is held by an assessee for professional or business purposes is called capital gains. When the assessee sells or transforms his capital asset which was held as an investment, he gains profit. 

Calculations of income from capital gains can be done through the following steps:

  1. Compute your long-term capital gains from your total sale of assets.
  2. Compute your short-term capital gains from your total sale of assets.
  3. Claim your deductions after these steps.

Income from Business:

Income from business and profession simply translates to any revenue shown by an assessee in the profit and loss account of a business entity after considering all the expenditures. Any revenue earned whether positive or negative is taxable. It’s mandatory for all business entity holders to file their income tax returns before 31st July of the ongoing assessment year. 

Income from other sources:

  1. Income that is not eligible for exemption but cannot be placed under heads like salary, income from capital gains, house property, business/profession is kept under the heading of income from other sources.
  2. All the dividends received are mentioned under this head
  3. Interest earned from deposits and bonds are mentioned under this heading
  4. One-time income like winning a lottery, game, racing, gambling, or betting is mentioned under this head.
  5. Gifts received in the form of money or property and are eligible for taxation are kept under this head.
