“Section 143(43)”

Foreign exchange fluctuations, whether gains or losses, are inextricably linked to the underlying business transaction and must be accounted for under the mercantile system. The Supreme Court also affirmed the standard accounting principle of valuing stock at cost or net realisable value, whichever is lower.

The "Purpose Test" determines whether an incentive or subsidy is a capital or revenue receipt for income tax purposes. If the incentive's purpose is to enable an assessee to set up a new industry or make investments in capital assets, it is a capital receipt and not taxable.

Goodwill, whether arising from an amalgamation or a slump sale, is an intangible asset eligible for depreciation under Section 32(1) of the Income-tax Act. While the assessee must prove the existence and valuation of such goodwill, it is recognized as a depreciable asset.

A subsidy is treated as a revenue receipt if the assessee is free to use the money in its business as it likes and is not obligated to spend it for a specific capital purpose, such as acquiring assets or repaying loans.

Employees' contributions to welfare funds are an allowable deduction if paid before the due date for filing the income-tax return under section 139(1), even if the payment is made beyond the due date specified by the respective welfare fund Acts, as per the provisions of section 43B.

Expenditure incurred for increasing a company's share capital or expanding its capital base, such as expenses related to the issue of shares, constitutes capital expenditure. Such expenses are not deductible as revenue expenditure under Section 37(1) of the Income-tax Act, 1961, even if they incidentally benefit the business.

Employees' contribution to provident fund and ESI, if paid by the assessee before the due date for filing the return of income under section 139(1), is an allowable deduction under section 43B. No distinction is drawn between employer's and employee's contributions for the purpose of section 43B.

Interest, sales tax, and purchase tax subsidies received by an assessee are generally considered capital receipts, not revenue income, for income tax purposes.
