Undisclosed income: profit-rate assessment permitted; penalty under Section 158BFA limited to excess over return under Section 158BC.

Undisclosed income revealed on search may be determined by reference to an appropriate profit rate of receipts rather than by treating full recovered receipts as income; applying that principle the Tribunal's adoption of 15% of receipts as undisclosed income is upheld in favour of the assessee. Penalty under Section 158BFA is a civil liability contingent on returns filed under the special search-return regime, and may be imposed only on the portion of undisclosed income finally determined to exceed the income shown in the return; penalty issue is remanded for recomputation and imposition only on the excess.

Issues: (i) Whether undisclosed income revealed on search can be assessed by treating the entire receipts as income or by adopting a profit percentage of receipts; (ii) Whether penalty under Section 158BFA is a quasi criminal proceeding requiring mens rea or a civil liability and, if civil, whether penalty can be imposed where return under Section 158BC has been filed.

Issue (i): Whether the Tribunal was correct in directing levy of income tax only on 15% of the total receipts disclosed in proceedings under Section 158BC of the Income tax Act, 1961, instead of treating the entire recovered receipts as undisclosed income.

Analysis: Section 158B(2) defines ''undisclosed income'' as including income based on entries or transactions not disclosed; it does not deem entire recovered receipts to be the undisclosed income. Where sale consideration recovered on search was not reflected in books or returns, the undisclosed income must be determined; the Tribunal examined net profit statements and adopted 15% as representative profit. Provisions of Chapter XIVB and the applicability of assessment provisions (including Section 158BC and related provisions) permit determination of undisclosed income by reference to appropriate profit rates rather than treating full receipts as income.

Conclusion: In favour of Assessee. The Tribunal correctly directed adoption of 15% of the undisclosed receipts as undisclosed income and the Revenue's appeal on assessment is rejected.

Issue (ii): Whether penalty under Section 158BFA is a quasi criminal proceeding requiring proof of mens rea, or a civil liability, and the scope of imposition where returns under Section 158BC have been filed.

Analysis: The provisos to Section 158BFA(2) show that penalty is contingent on determination in excess of returns filed under Section 158BC; statutory obligation to file returns and pay tax is a civil liability. Precedents distinguishing Hindustan Steel where mens rea was required are applicable where the statutory duty is civil. Penalty cannot be imposed where the assessee has filed the return under Section 158BC and paid tax on the returnable income unless the final determined undisclosed income exceeds the income shown in that return; penalty is limited to the excess portion.

Conclusion: In favour of Revenue to the limited extent that penalty is a civil liability and may be imposed only on the portion of undisclosed income determined in excess of the income shown in the return filed under Section 158BC; otherwise in favour of Assessee. The Tribunal's order setting aside penalty is to be modified by remand for recomputation and imposition of penalty only on the excess as directed.

Final Conclusion: The assessment appeal is rejected insofar as the Tribunal's adoption of 15% of receipts as undisclosed income is upheld; the penalty appeal is allowed only to the extent of permitting recomputation and imposition of penalty on amounts determined in excess of returns filed under Section 158BC, with remand for computation.

Ratio Decidendi: Undisclosed income revealed on search is to be determined on its merits and may be assessed by adopting an appropriate profit rate of receipts rather than treating entire recovered receipts as income; penalty under Section 158BFA is a civil liability and is leviable only on the portion of undisclosed income determined to be in excess of the income shown in a return filed under Section 158BC of the Income tax Act, 1961.
