Direct nexus test for section 10B: ancillary receipts and windfall income do not qualify for deduction.

Deduction under section 10B was denied for three receipts because each lacked direct derivation from the industrial undertaking. Interest on fixed deposits kept as security was held to arise from the deposit itself, not from manufacturing or export activity, so it was ineligible. Sundry balances written off related to earlier years and were not attributable to the relevant year or export operations, so they did not qualify. Sale proceeds of unutilised building material were treated as a windfall receipt and income from other sources, not profit derived from the undertaking. The Tribunal therefore upheld disallowance of deduction on all three amounts.

Issues: (i) Whether interest earned on fixed deposits kept as security with the Central Excise Department was eligible for deduction under section 10B; (ii) Whether the amount written off on sundry balances was profit derived from the industrial undertaking for deduction under section 10B; (iii) Whether sale proceeds of unutilised building material constituted income derived from the industrial undertaking for deduction under section 10B.

Issue (i): Whether interest earned on fixed deposits kept as security with the Central Excise Department was eligible for deduction under section 10B.

Analysis: The security deposit was required for the export business, but the interest arose from the deposit itself and not from the industrial undertaking. Deduction under section 10B is confined to profit derived from the industrial undertaking.

Conclusion: The interest on fixed deposits was not eligible for deduction under section 10B and the disallowance was upheld.

Issue (ii): Whether the amount written off on sundry balances was profit derived from the industrial undertaking for deduction under section 10B.

Analysis: The written off balances related to earlier years and were not attributable to the relevant accounting year or to export activity. Such receipts could not be treated as income derived from the industrial undertaking.

Conclusion: The sundry balances written off were not eligible for deduction under section 10B and the disallowance was upheld.

Issue (iii): Whether sale proceeds of unutilised building material constituted income derived from the industrial undertaking for deduction under section 10B.

Analysis: The material was not acquired by the assessee and the sale of unutilised material was treated as a windfall receipt. It was rightly assessed as income from other sources and not as income derived from the industrial undertaking.

Conclusion: The sale proceeds of building material were not eligible for deduction under section 10B and the disallowance was upheld.

Final Conclusion: The Tribunal held that none of the three receipts had the requisite direct nexus with the industrial undertaking, so the assessee was not entitled to deduction under section 10B on those amounts.

Ratio Decidendi: For deduction under section 10B, the receipt must be directly derived from the industrial undertaking and not merely connected with the business or export operations; ancillary, incidental, or windfall receipts do not qualify.
