Book rejection and best-judgment profit estimation hinge on reliable stock records, comparable margins, and supporting evidence.

Failure by a manufacturing assessee to maintain day-to-day production and stock registers can justify rejection of books under section 145 where substitute records do not reliably show stock movement, wastage or by-products. Once the accounts are rejected, profit may be estimated on a best-judgment basis, but the estimate must be reasonable and supported by comparable material; an arbitrary gross profit rate was therefore modified. Unexplained cash credits and a suspense account entry were sustained because identity and confirmation evidence was inadequate. Commission expenditure was allowed only for the payment supported by loan-arranging service details. Deductions under sections 80HH and 80-I were to be recomputed on the revised profit basis.

Issues: (i) whether the books of account were rightly rejected under section 145 for want of day-to-day production and stock records and for reliance on substitute records; (ii) whether the gross profit could be estimated by the Revenue on the facts of the case; (iii) whether the additions sustained under section 68, the suspense account item and the commission disallowance were justified; and (iv) whether deductions under sections 80HH and 80-I were to be recomputed on a proportionate basis.

Issue (i): whether the books of account were rightly rejected under section 145 for want of day-to-day production and stock records and for reliance on substitute records.

Analysis: The accounts were held to be incomplete and unreliable because the assessee, though engaged in manufacturing, had not maintained day-to-day production and stock registers. The substitute records were based on a balancing method and did not reflect actual stock movements, wastage or by-products. In these circumstances, the Assessing Officer's dissatisfaction about the correctness and completeness of the accounts was treated as justified.

Conclusion: The rejection of books of account was upheld and was against the assessee.

Issue (ii): whether the gross profit could be estimated by the Revenue on the facts of the case.

Analysis: Once the books were rejected, a best judgment estimate was warranted. However, the estimate had to be reasonable and based on available material. The turnover adopted by the first appellate authority was accepted, but the gross profit rate of 12.5 per cent was found to be arbitrary. The Tribunal preferred an average of the comparable gross profit rates emerging from the assessee's own earlier years, as a fairer measure.

Conclusion: The gross profit addition was modified in part and was partly in favour of the assessee.

Issue (iii): whether the additions sustained under section 68, the suspense account item and the commission disallowance were justified.

Analysis: The assessee failed to discharge the burden regarding the cash credits for the two parties concerned, as the confirmations and identity particulars were insufficient. The suspense account entry was also unexplained on merits. As to commission, the payment to one party was accepted because supporting details of loan-arranging services were furnished, but the claim relating to the other party remained unproved. Thus, only the commission payment to one payee was deleted.

Conclusion: The cash credit additions and suspense account addition were sustained, while the commission disallowance was partly deleted, resulting in a mixed outcome but substantially against the assessee on these items.

Issue (iv): whether deductions under sections 80HH and 80-I were to be recomputed on a proportionate basis.

Analysis: Since the accounts were rejected and the profits were to be recomputed, the deductions linked to industrial profits also had to be recalculated on a proportionate basis. The Tribunal held that the Assessing Officer's approach on apportionment was correct in principle, but the recomputation had to follow the revised gross profit figure determined by the Tribunal.

Conclusion: The deductions under sections 80HH and 80-I were directed to be recomputed, which was partly in favour of the assessee.

Final Conclusion: The appeal succeeded only to a limited extent. The books rejection was sustained, the gross profit rate and related deductions were sent for recomputation on a modified basis, and some ancillary relief was granted on commission expenditure.

Ratio Decidendi: In the case of a manufacturing assessee, failure to maintain day-to-day production and stock records can justify rejection of books under section 145, and once the accounts are rejected, profits may be estimated on a reasonable best-judgment basis using reliable comparative material.
