Section 80P(2)(a)(i) of the Income-tax Act, 1961 provides for a deduction in respect of the income of co-operative societies. Specifically, it allows for the deduction of income earned by a co-operative society from the business of banking or providing credit facilities to its members. This section is significant as it aims to promote the cooperative movement by providing tax incentives to co-operative societies, thereby supporting their financial viability and growth. The statutory test requires that the society must be registered as a co-operative society and the income must be derived from activities specified under this section. The burden of proof lies on the taxpayer to demonstrate eligibility for the deduction. In practice, this provision is crucial for co-operative societies as it can substantially reduce their taxable income, thus enhancing their ability to serve their members effectively.
