“commercial expediency”

Interest paid on borrowed funds cannot be disallowed merely because the assessee made interest-free advances, provided those advances were made for business purposes and commercial expediency. The Revenue cannot dictate a businessman's commercial decisions, but the assessee bears the onus to prove the business expediency.

Expenditure is classified as revenue or capital based on its practical business effect, necessity, or expediency, rather than solely on the juristic classification of rights; an enduring benefit does not automatically make an expenditure capital if it facilitates trading operations or business efficiency.

When mixed funds are available, interest-free advances are presumed to be made from the assessee's own interest-free funds, preventing disallowance of interest expenditure under section 36(1)(iii). This principle also applies to section 14A disallowance, where interest expenditure is not disallowed if surplus funds are available and no direct nexus is established with borrowed funds for investments earning exempt income.

When there is a nexus between an expenditure and the purpose of business, incurred on grounds of commercial expediency, the Revenue cannot question its reasonableness or assume the role of the businessman to compel profit maximization. This principle applies even if the business is not that of the assessee itself.

The Revenue cannot substitute its judgment for that of a businessman regarding the necessity or reasonableness of an expenditure. If an expense is incurred wholly and exclusively for business purposes, it is deductible, and the Revenue cannot question its commercial expediency.

For interest on borrowed capital to be deductible under Section 36(1)(iii), there must be a nexus between the use of the borrowed funds and the purpose of the business. This decision has been overruled by the Supreme Court in Munjal Sales Corporation v. CIT (2008).

Expenditure must be commercially expedient for carrying on the business, and it is not for revenue authorities to dictate how an assessee should conduct its business. The court will not question the business expediency of a transaction, even if a third party also benefits.

An expense incurred by an assessee for its own business, such as advertising, marketing, and promotional (AMP) expenses, cannot be disallowed merely because it incidentally or indirectly benefits the assessee's sister concerns or associated enterprises.
