Best judgment assessment permits honest, rational enhancement where returns and explanations are not satisfactorily accepted.

Under section 12 of the Orissa Sales Tax Act, 1947, a return-based assessment is permissible only when the assessing authority is satisfied that the returns are correct and complete. If the dealer does not satisfactorily comply with a notice and the explanations or material produced are not accepted, the authority may reject the books and complete the assessment to the best of its judgment. In such an assessment, some estimate is inevitable, but it must be honest, rational, and free from arbitrariness. An enhancement is not excessive merely because it exceeds detected suppression where the suppression period is limited and further undisclosed transactions may reasonably be inferred.

Issues: (i) whether the assessing authority was entitled to make a best judgment assessment where the dealer had furnished returns but the explanations and material produced in response to notice were not accepted; (ii) whether the enhancement made in the best judgment assessment was excessive and liable to be interfered with.

Issue (i): Whether the assessing authority was entitled to make a best judgment assessment where the dealer had furnished returns but the explanations and material produced in response to notice were not accepted.

Analysis: Under section 12 of the Orissa Sales Tax Act, 1947, assessment on returns is made only when the authority is satisfied that the returns are correct and complete. Where the authority is not so satisfied and the dealer does not comply with the notice to its satisfaction, the case falls within the provision enabling assessment to be made to the best of judgment. Compliance is not to be judged merely by physical appearance or production of books, but by whether the statutory notice has been satisfactorily met. If the explanations are not accepted and the authority finds improper compliance, the dealer cannot insist on an assessment confined to the returned figures.

Conclusion: The assessing authority was entitled to reject the books and complete the assessment to the best of his judgment.

Issue (ii): Whether the enhancement made in the best judgment assessment was excessive and liable to be interfered with.

Analysis: In a best judgment assessment, some guesswork is inevitable, but the estimate must be honest and based on a rational foundation, free from arbitrariness. The detected suppressions were not exhaustive, the suppression covered only a short period of the assessment year, and there was material to indicate that further suppressed transactions may have existed. In such circumstances, the quantum of enhancement could not be treated as excessive merely because it exceeded the detected suppression.

Conclusion: The enhancement was not shown to be excessive and did not call for interference.

Final Conclusion: The reference was answered in support of the revenue, upholding the enhanced best judgment assessment made by the taxing authority.

Ratio Decidendi: Where a taxing authority is not satisfied with the correctness and completeness of returns and finds that the dealer has not satisfactorily complied with the notice issued for assessment, it may complete the assessment to the best of its judgment, and such estimate will stand if it is an honest and rational assessment not shown to be arbitrary.
