Income estimation must rest on evidentiary foundation; arbitrary increases in rates or quantities are removable and recomputation ordered.

Rejection of books of account was sustained in principle but the Tribunal held that income estimation requires an evidentiary foundation and must not rest on arbitrary numeric increases; accordingly the AO's increases in hire rate and quantity were deleted and estimated receipts were recomputed using the assessee's actual figures (182,959 bags at the actual hire rate) with net profit fixed at the average rate of the preceding two years (25%), favouring the assessee. The Tribunal further directed allowance of partners' remuneration and interest on partners' capital as claimed, adjusted interest collected from farmers within the revised computation, producing a revised net taxable profit.

Issues: (i) Whether the books of accounts could be rejected and income estimated under section 145(3) of the Income-tax Act, 1961; (ii) Whether the Assessing Officer could increase the hire charges per bag and the quantity of bags for estimating receipts and apply a 25% net profit rate; (iii) Whether additions made for interest charged from farmers and disallowance of partners' remuneration and interest on capital were justified.

Issue (i): Validity of rejection of books of account and estimation under section 145(3) of the Income-tax Act, 1961.

Analysis: The Tribunal reviewed the reasons recorded by the Assessing Officer concerning inconsistent trading results, suspect vouchers for loading/unloading/grading, suppression of rental receipts and the manner of maintenance of accounts. Considering the totality of facts and material on record, the Tribunal examined whether the AO's findings sufficed to reject the books and estimate income under section 145(3).

Conclusion: The rejection of books of account and estimation under section 145(3) is upheld in principle, but the estimation requires modification as directed by the Tribunal in subsequent issues in favour of the assessee.

Issue (ii): Legitimacy of the AO's increase of hire charges per bag from Rs.56 to Rs.70 and increase of bags from 182,959 to 185,788 for computing estimated receipts and application of 25% net profit rate.

Analysis: The Tribunal considered the comparative year data, the assessee's explanation for increased operating expenses (loading, unloading, grading), and evidence of actual hire charge of Rs.56 per bag and actual quantity of 182,959 bags. The AO's upward revisions of rate and quantity were examined for evidentiary basis and arbitrariness. The Tribunal accepted the use of the average net profit rate of the preceding two years but assessed the correctness of the AO's specific numeric alterations.

Conclusion: The AO's arbitrary increase of hire charges to Rs.70 per bag and the upward revision of quantity to 185,788 bags are deleted. The Tribunal directed computation of estimated receipts using 182,959 bags at Rs.56 per bag and adopting net profit at 25% (average of preceding two years), which favours the assessee.

Issue (iii): Correctness of additions for interest charged from farmers and disallowance regarding partners' remuneration and interest on partners' capital.

Analysis: The Tribunal noted that the AO had separately added interest charged from farmers of Rs.4,64,470 after estimating net profit and had allowed interest on partners' capital but disallowed partners' remuneration. The Tribunal examined whether these adjustments were consistent with the revised estimation and applicable deductions under section 40(b).

Conclusion: The Tribunal directed that net profit be computed on revised estimated receipts (182,959 bags x Rs.56) at 25%, allowed deduction for interest on partners' capital of Rs.11,77,847 and partners' remuneration of Rs.1,49,655 as claimed, resulting in net taxable profit of Rs.12,33,924. This disposition partly favours the assessee.

Final Conclusion: The Tribunal upholds the principle of rejection of books but modifies the AO's estimation methodology and numeric determinations, deleting arbitrary upward adjustments and directing recomputation of income in accordance with the Tribunal's specified figures; the assessee's appeal is partly allowed.

Ratio Decidendi: Where books are rejected under section 145(3), estimation must be based on evidentiary foundation and may not rest on arbitrary increases in rates or quantities; estimation by reference to the actual figures and average net profit of preceding years is appropriate when supported by records.
