Penalty under section 271AAB requires undisclosed income as exhaustively defined in its Explanation; a surrender made during a search does not alone establish that statutory character. Land and other advances represent application or outflow of funds rather than an unrecorded income inflow, and deeming provisions for unexplained investments cannot be automatically applied to this self-contained penal provision. Uncorroborated diary notings without verifiable particulars cannot independently prove real transactions or undisclosed income. As the amount was accepted as current-year business income without a requisite finding of undisclosed income, deletion of the penalty on the surrendered advances was sustained.
