Block assessment additions require incriminating search material, not presumptions from an incomplete gift register.

In a block assessment under Chapter XIV-B, an addition for sales promotion expenses could not be sustained as undisclosed income without incriminating material found in the search. The Tribunal held that undisclosed income must be linked to search evidence and cannot rest on conjecture, presumptions, or a review of completed assessments. Here, gift purchases were fully vouched, payments were made by account payee cheques, no undisclosed stock was found, no issue on sales promotion expenses arose in the section 132(4) examination, and the seized gift register was incomplete and confined to one period. The addition was deleted and the assessee's appeal succeeded.

Issues: Whether, in a block assessment under Chapter XIV-B, an addition towards sales promotion expenses could be sustained as undisclosed income on the basis of an incomplete gift register and presumptions drawn from it, in the absence of incriminating material found in the search.

Analysis: Chapter XIV-B is confined to undisclosed income detected as a result of search. The expression "undisclosed income" must be linked to material or evidence found during search, and the provision does not authorise roving enquiries or a review of completed assessments on conjecture. Here, the purchases of gift articles were fully vouched, payments were by account payee cheques, no undisclosed stock was found, no question on sales promotion expenses was put during examination under section 132(4), and the only seized gift book related to one period and was incomplete. Its contents were not shown to establish concealment or to justify a year-wise addition for the block period.

Conclusion: The addition could not be sustained as undisclosed income and was liable to be deleted in favour of the assessee.

Final Conclusion: The block assessment addition on account of sales promotion expenses was set aside, and the appeal succeeded.

Ratio Decidendi: In a block assessment under Chapter XIV-B, an addition can be made only on the basis of incriminating material found in search, and not on presumptions or unsupported estimates concerning matters already disclosed in regular assessment.
