Block assessment excludes income below taxable limit; factual findings on seized assets raised no substantial legal question.

Income of a previous year below the taxable limit cannot be included as undisclosed income in block assessment merely because no return was filed under section 139; if, after Tribunal deletions or reconsideration on remand, an assessment year falls below the taxable limit, it must be excluded from the block period computation. Additions based on assets said to have been acquired by the assessee's parents, and the related burden of proof argument, were upheld as factual findings drawn from search material and explanations. No substantial question of law arose under section 260A, so the factual conclusions stood.

Issues: (i) Whether, in block assessment, income of a previous year below the taxable limit but not returned under section 139 could be included in undisclosed income under section 158BC read with section 158BB(1)(c); (ii) Whether the additions relating to assets claimed to have been acquired by the parents of the assessee, and the plea regarding burden of proof, gave rise to a substantial question of law warranting interference under section 260A.

Issue (i): Whether, in block assessment, income of a previous year below the taxable limit but not returned under section 139 could be included in undisclosed income under section 158BC read with section 158BB(1)(c)

Analysis: The legal position was treated as settled that for block assessment purposes, income of a previous year which was below the taxable limit could not be included merely because no return had been filed under section 139. The Court further clarified that if, after deletions made by the Tribunal or after fresh consideration on remand, the income of any assessment year fell below the taxable limit, that year's income would not form part of the undisclosed income for the block period.

Conclusion: The issue was answered in favour of the assessee on the legal principle, with the clarification that only income of years remaining above the taxable limit could be included in undisclosed income.

Issue (ii): Whether the additions relating to assets claimed to have been acquired by the parents of the assessee, and the plea regarding burden of proof, gave rise to a substantial question of law warranting interference under section 260A

Analysis: The Tribunal had examined each item of asset on the basis of the search material and the assessee's explanation, deleting some additions and rejecting others for cogent reasons. Those conclusions were based on detailed appreciation of evidence and were essentially findings of fact. The Court also held that, on the scheme of section 158BB and Chapter XIV-B, the Tribunal had correctly appreciated the evidence even on the question of burden of proof.

Conclusion: The issue was decided against the assessee; no substantial question of law arose on these findings, and the Tribunal's factual conclusions were upheld.

Final Conclusion: The appeal failed, with only the limited clarification that any assessment year falling below the taxable limit, after the Tribunal's deletions or the Assessing Officer's reconsideration on remand, would not be included in the block assessment as undisclosed income.

Ratio Decidendi: In block assessment, income of a year below the taxable limit cannot be treated as undisclosed income merely because no return was filed, and detailed factual findings on seized material and explanations of the assessee do not raise a substantial question of law in appeal under section 260A.
