Section 36(1)(iii) of the Income Tax Act

Where an assessee claims that investments were made out of own funds, interest disallowance under Section 14A read with Rule 8D may not apply if the assessee demonstrates the availability of sufficient interest-free funds to cover such investments.

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.

When an assessee possesses interest-free funds sufficient to cover investments yielding tax-free income, it is presumed that such investments were made from these interest-free funds, precluding disallowance of interest expenditure under Section 14A.

Disallowance under Section 14A cannot exceed the exempt income earned. The Assessing Officer must record satisfaction regarding the assessee's accounts before making any disallowance.

The mixed fund theory is affirmed, holding that no disallowance of interest expenditure under Section 14A can be made if the assessee possesses sufficient non-interest bearing funds, such as capital and reserves, to cover investments made in tax-free securities.

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.

Where an assessee has sufficient interest-free funds, investments yielding exempt income are presumed to be made out of such funds, precluding disallowance of related interest expenditure under section 14A.

For deductions under Section 57(iii) relating to "Income from Other Sources," an expenditure is allowable if it is laid out wholly and exclusively for the purpose of making or earning such income, even if no income is actually earned in that previous year.

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.
