Section 48 of the Income Tax Act

For attracting Section 14A disallowance, there must be a proximate cause relating the expenditure to actual tax-exempt income, and such disallowance is not automatic but requires positive material. Additionally, Section 94(7) on dividend stripping only ignores losses to the extent of dividend received for assessment years post-April 1, 2002, allowing the remaining loss.

A statute should not be construed to permit double deduction for the same expenditure unless specifically provided by law.

Income is taxable only when it represents real income, not notional income. It accrues only when there is a vested right to receive it, typically upon the occurrence of a transfer or event, rather than merely on a time basis.

A transfer of immovable property, for the purpose of capital gains under section 2(47)(v) of the Income-tax Act, occurs only when the agreement allowing possession in part performance of a contract is a registered instrument, as mandated by Section 53A of the Transfer of Property Act.

Surrender of tenancy rights is a transfer of a capital asset, and the consideration received is a capital receipt subject to capital gains tax. If the cost of acquisition cannot be determined, the transfer of such an asset was not taxable under capital gains prior to the amendment of Section 55(2) in 1995.

Income accrues when it becomes due, vesting the assessee with the right to claim the amount, even if payment is not immediate. It requires a corresponding liability from the other party to pay, emphasizing real rather than hypothetical accrual, particularly for assessees using the mercantile system of accounting.

Interest received on delayed payments for sales is considered part of the sale proceeds and is eligible for deduction under Section 80-IA as business income.

For capital assets acquired by gift or will, the indexed cost of acquisition under Section 48 is computed with reference to the year the previous owner first held the asset. The period of holding for determining if an asset is long-term also includes the previous owner's holding period, as per Section 2(42A).

The Supreme Court examined the validity of customs duty on newsprint in the context of Article 19(1)(a), emphasizing that the press advances public interest by publishing facts and opinions crucial for a democratic country.
