Section 254 of the Income Tax Act

Payments for the use of equipment, such as satellite transponders, do not constitute 'royalty' under Section 9(1)(vi) of the Income-tax Act, 1961, or under applicable tax treaties, especially when there is no transfer of the right to use a process or underlying technology.

An assessee can make an additional claim for deduction or file a revised computation of income during assessment proceedings, even if a revised return of income has not been filed. Such additional claims or grounds can also be admitted at the appellate stage.

The Supreme Court restores the matter for ascertaining whether the difference between the fair market price and concessional price of sugar supplied by a cooperative sugar factory to its members should be added to its total income, considering relevant factors like state cooperative society directions.

Expenditure providing an enduring advantage, such as upfront lease rent for land, is revenue expenditure if no capital asset is acquired or generated, allowing for deduction under Section 37, even when capitalized in the books of account.

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.

The Supreme Court established the foundational test for distinguishing between capital and revenue expenditure, holding that the aim and object of the expenditure and whether it brings into existence an asset or an advantage of an enduring nature determines its character, irrespective of the payment method. An advantage lasting five years or more can be considered enduring.

An expenditure is classified as either capital or revenue; the 'enduring benefit' test is a key criterion for this distinction, and income tax law does not generally recognize deferred revenue expenditure unless specifically provided.

Sections 4 and 5 of the Income Tax Act, which define total income and chargeability, are subject to Section 90, meaning that Double Taxation Avoidance Agreements (DTAAs) override the Act's provisions in case of a conflict.

A contribution made towards the construction of roads for facilitating business operations, such as transportation of raw materials, constitutes a deductible revenue expenditure even if it provides a long-term advantage, provided no tangible or intangible capital asset is acquired by the assessee.
