Under-invoicing and estimated profit additions fail without corroboration or defective books, with one issue sent back for fresh review.

Income-tax additions for alleged under-invoicing could not be sustained solely on excise show-cause material and settlement proceedings because no direct evidence of suppressed turnover was available; the Tribunal restored that issue to the Assessing Officer for fresh examination. It also held that gross profit could not be estimated where the books of account were maintained, no defects were pointed out, and the books were not rejected; the estimated addition was therefore deleted. The decision underscores that excise proceedings do not by themselves determine income under the Income-tax Act and that estimation requires a proper evidentiary foundation.

Issues: (i) Whether additions made towards alleged under-invoicing on the basis of excise show-cause material and settlement proceedings could be sustained in income-tax proceedings. (ii) Whether the gross profit addition by estimation for want of defects in the books of account and without rejecting the books was justified.

Issue (i): Whether additions made towards alleged under-invoicing on the basis of excise show-cause material and settlement proceedings could be sustained in income-tax proceedings.

Analysis: The additions were founded on annexures to an excise show-cause notice and the order of the Settlement Commission. The Tribunal noted that there was no direct evidence establishing suppressed turnover or under-invoicing and that the excise proceedings were concerned with duty liability, not with determination of income under the Income-tax Act. It also accepted that the assessee's explanation regarding rate differences attributable to the sizes of granite slabs required factual verification.

Conclusion: The additions on this issue could not be sustained as made and the matter was restored to the Assessing Officer for fresh examination in accordance with law.

Issue (ii): Whether the gross profit addition by estimation for want of defects in the books of account and without rejecting the books was justified.

Analysis: The Tribunal found that the assessee had maintained books of account and the Assessing Officer had not pointed out any defect in those books. In such circumstances, estimation of income was held impermissible, particularly when the seized material had no relevance to the year under appeal. The addition therefore lacked the foundation required for estimation in the absence of rejection of books.

Conclusion: The gross profit addition was deleted.

Final Conclusion: The appeals were disposed of by restoring the under-invoicing issue for fresh adjudication and by deleting the estimated gross profit addition, resulting in partial relief to the assessee overall.

Ratio Decidendi: An income-tax addition cannot rest solely on excise proceedings or unsupported annexures without corroborative evidence, and estimation of business income is not justified unless the books of account are first found defective and rejected.
