Block assessment additions need incriminating search material; a valuation report alone cannot sustain undisclosed income.

In block assessment proceedings under the Income-tax Act, an addition cannot be sustained solely on a District Valuation Officer's report unless search material shows undisclosed income. Where the search yields no incriminating document or evidence of suppressed or unrecorded construction expenditure, a mere valuation-based estimate of higher cost does not qualify as search material for taxing the difference as undisclosed income for the block period. On that basis, the addition was held unsustainable and the Revenue's challenge failed.

Issues: Whether, in a block assessment under the Income-tax Act, addition could be sustained solely on the basis of the District Valuation Officer's report in the absence of incriminating material found during search.

Analysis: The search did not yield material showing that the construction expenditure had been suppressed or left unrecorded in the books. The assessment of undisclosed income was founded essentially on the valuation difference reported by the District Valuation Officer. In block assessment proceedings, the determining basis must be evidence unearthed as a result of search or requisition, and the valuation report by itself does not constitute search material. Where no incriminating document or evidence is found, a mere estimate of higher construction cost cannot justify bringing the difference to tax as undisclosed income for the block period.

Conclusion: The addition based solely on the valuation report was unsustainable and the challenge by the Revenue failed.
