Concealment penalty requires proof of culpable conduct; rejection of an explanation in assessment alone is not enough.

Penalty for concealment of income under Section 271(1)(c) could not be sustained merely because the assessee's explanation for a credit was rejected in assessment proceedings. The material on record did not show that the explanation was inherently false, improbable, artificial or unnatural, and the statutory Explanation could be applied only where fraud, gross neglect or wilful neglect was established. The distinction between assessment and penalty proceedings was material, and additional evidence of culpable conduct was required before concealment could be inferred. On that basis, cancellation of the penalty was upheld in favour of the assessee.

Issues: Whether penalty for concealment of income could be sustained on the facts of the case under Section 271(1)(c) of the Income-tax Act, 1961, including the effect of the statutory Explanation.

Analysis: The assessee's explanation regarding the nature and source of the credit was not shown to be inherently false, improbable, artificial or unnatural. The mere rejection of that explanation in assessment proceedings did not by itself establish concealment for penalty purposes. The statutory Explanation could not be invoked unless the material on record showed fraud, gross neglect or wilful neglect attributable to the assessee. The distinction between assessment proceedings and penalty proceedings was material, and additional evidence was required before concealment could be inferred.

Conclusion: Penalty for concealment was not justified, and the cancellation of penalty was upheld in favour of the assessee.

Final Conclusion: The departmental appeal failed because the record did not establish concealment or the culpable conduct necessary to sustain penalty.

Ratio Decidendi: Mere rejection of an assessee's explanation in assessment proceedings does not, without more, establish concealment for penalty purposes; penalty under Section 271(1)(c) can be sustained only where the material shows culpable conduct such as fraud or gross or wilful neglect.
