Section 56 of the Income Tax Act

The interest income earned by a cooperative society from investing its surplus funds in fixed deposits with banks is not "derived from" its eligible business activities and is taxable as "income from other sources" under Section 56, thus not qualifying for deduction under Section 80P.

Interest income earned by a cooperative society from surplus deposits or investments held with a cooperative bank is not eligible for deduction under Section 80P(2)(d) of the Act.

Section 80P(4) serves as a proviso to Section 80P(1) and (2), excluding only cooperative banks that are cooperative societies and possess an RBI license for banking business. Its purpose is to exclude cooperative banks operating like commercial banks that lend money to the public.

A cooperative society is eligible for deduction under Section 80P(2)(a)(i) if it is engaged in cooperative activities. It also clarifies the allowability of deduction under Section 80P(2)(d) for interest income received from investments made in cooperative banks, after duly considering the Supreme Court's decision in Totgars Co-operative Sale Society Ltd.

A co-operative credit society engaged in banking business with the general public, accepting deposits from non-members and advancing loans to non-members, is treated as a co-operative bank. Such a society falls under the exclusionary clause of Section 80P(4) and is not eligible for deduction under Section 80P(2)(a)(i).

Interest income earned by a co-operative society from investments, particularly with co-operative banks, is not eligible for deduction under Section 80P as it is not attributable to the core business activities of the society and constitutes "other income", not "profits and gains of business".

Interest earned by a Co-operative Society from investing fixed deposits in banks is entitled to a deduction under Section 80P(2)(a)(i) of the Income-tax Act.

Interest income earned by a co-operative society from deposits or investments made in a co-operative bank is not eligible for deduction under Section 80P(2)(d) of the Income Tax Act, 1961, in view of Section 80P(4).

Interest income earned by a co-operative society from temporary deposits with other banks, when such deposits are made from its business funds, qualifies as business income eligible for deduction under Section 80P(2)(a)(i) and not as income from other sources.

The Supreme Court affirmed the doctrine of mutuality, holding that contributions received from and returned to members for a common purpose do not constitute taxable profits. However, income from transactions with non-members or interest earned from investments in external entities (like cooperative banks) may break the mutuality chain and be taxable under Section 56, falling outside the scope of Section 80P deductions.
