Penalty under Section 12(3)(b) requires an incorrect return and best judgment assessment; debatable additions alone are insufficient.

Penalty under Section 12(3)(b) of the Tamil Nadu General Sales Tax Act was held to require an incorrect or incomplete return and an assessment made on best judgment after rejection of the return and accounts. Additions arising from disputed or debatable issues, including treatment of sales and cash incentives, did not by themselves satisfy that standard. The later inserted Explanation to Section 12(3) was held inapplicable to the assessment year in question. On those facts, the penalty was not justified and the impugned penalty order could not be sustained.

Issues: Whether penalty under Section 12(3)(b) of the Tamil Nadu General Sales Tax Act, 1959 was sustainable where the additions to turnover did not arise from a best judgment assessment and the return was not found to be incorrect or incomplete.

Analysis: Section 12(3)(b) contemplates penalty where the assessee submits an incorrect or incomplete return and the assessment proceeds on the basis of rejection of the return and accounts. The additions made in the present case arose from disputed and debatable issues, including treatment of certain sales and cash incentives, and did not lead to a best judgment assessment. The later inserted Explanation to Section 12(3) was held not applicable to the assessment year in question. The penalty was therefore not justified on the facts found.

Conclusion: Penalty under Section 12(3)(b) was not attracted and the assessee succeeded.

Final Conclusion: The impugned penalty order could not be sustained, and the assessee was entitled to relief.

Ratio Decidendi: Penalty under Section 12(3)(b) is attracted only where the return is incorrect or incomplete and the assessment is one of best judgment; additions on debatable issues do not by themselves justify such penalty.
