Section 2(24) of the Income-tax Act, 1961 provides a comprehensive definition of 'income' for the purposes of taxation. This section is significant as it outlines the various forms of receipts that are considered income and thus subject to tax. It includes not only the traditional forms of income such as profits and gains from business or profession, salaries, and capital gains, but also other receipts like dividends, voluntary contributions received by charitable trusts, and winnings from lotteries, races, and games. The section is crucial because it sets the foundation for what constitutes taxable income, thereby impacting the computation of tax liability. The burden of proof typically lies with the taxpayer to demonstrate that a particular receipt does not fall within the ambit of 'income' as defined under this section. In practice, this section is significant as it influences the scope of taxable income and can affect tax planning strategies.
