Best judgment assessment: flat gross-profit estimate upheld where unreliable accounts and trade conditions justified the rate.

Best judgment assessment under the proviso to Section 13 of the Income-tax Act, 1922 permitted estimation of income where the assessee kept no regular books and produced only limited records. The authorities could adopt a flat gross-profit rate if they reasonably considered trade conditions, the business margin and the unreliability of accounts. On the facts noted, the higher margin from largely outstation sales supported the estimate, and the flat 5% rate was not shown to be arbitrary or capricious. The court treated the estimate as a factual, judgment-based finding rather than an error of law, and upheld it.

Issues: Whether, after the proviso to Section 13 of the Income-tax Act, 1922 was applied, the application of a flat gross-profit rate of 5% to the estimated turnover was arbitrary or capricious so as to give rise to an error of law.

Analysis: The assessee maintained no regular books of account and produced only a limited register, so the proviso to Section 13 was properly invoked. Once that proviso applied, the income had to be estimated fairly on the basis of trade conditions and the average margin of profit in the business. The materials showed that the authorities had taken account of the nature of the trade, the absence of reliable accounts, and the fact that the sales were largely outstation sales carrying a higher margin. On that basis, the adoption of a flat rate was not shown to be arbitrary or capricious. The Court also treated the estimate, in these circumstances, as one based on judgment and fact rather than a question of law.

Conclusion: The application of the flat rate of 5% was upheld and the question was answered against the assessee.

Ratio Decidendi: Where best judgment assessment is warranted, an income estimate made by a reasonable and non-arbitrary flat rate, having regard to trade conditions and profit margins, is a finding of fact and does not by itself raise a question of law.
