Section 57(iii) deduction requires strict proof of nexus with income and reliable evidence for interest claims.

Deduction of interest under section 57(iii) is available only where the assessee proves, with reliable evidence, that the expenditure was incurred wholly and exclusively for earning income under the head 'Income from other sources'. In the absence of bank statements, satisfactory loan confirmations, and proof of the identity, genuineness, creditworthiness of creditors or the fund trail, the claim fails. Additional evidence must also satisfy the conditions for admission under Rule 46A; unsupported material is not enough. On these facts, the interest disallowance and refusal to admit the additional evidence were sustained.

Issues: Whether the disallowance of interest claimed under section 57(iii) and rejection of additional evidence were justified.

Analysis: The assessee failed to produce supporting documentary evidence, including bank statements and satisfactory confirmation of loans, to establish the identity, genuineness, and creditworthiness of the creditors or the fund trail. The expenditure was not shown to have been laid out wholly and exclusively for earning income assessable under the head 'Income from other sources'. The record also did not establish commercial expediency or that the dominant purpose of the borrowings was to earn such income. The additional evidence tendered was found insufficient and did not satisfy the conditions for admission under Rule 46A.

Conclusion: The disallowance of interest under section 57(iii) was upheld, the rejection of additional evidence was sustained, and the appeal was dismissed.

Ratio Decidendi: Deduction under section 57(iii) is allowable only when the expenditure is proved to have been incurred wholly and exclusively for earning income, and the assessee must substantiate the claim with reliable evidence; failure to do so justifies disallowance and refusal to admit insufficient additional evidence.
