Supervision receipts and tax deduction at source shaped the taxability dispute, with section 234B interest excluded where TDS applied.

Receipts from supervision, erection and commissioning were examined for taxability under the Income-tax Act and the applicable DTAA. On the stated facts, the assessee was found to have rendered only supervision simpliciter and not to have shown activities amounting to erection, assembly, testing or commissioning, so section 44BBB did not apply; the note also records that the Indian permanent establishment finding was upheld and the receipts were treated as fees for technical services under Article 7 read with sections 44D and 115A. On interest, where tax was deductible at source and had in fact been deducted, section 234B interest was held not leviable.

Issues: (i) Whether the assessee's receipts from supervision, erection, and commissioning activities were taxable under section 44BBB of the Income-tax Act, 1961 or outside the scope of that provision and the relevant treaty provisions. (ii) Whether interest under section 234B of the Income-tax Act, 1961 was leviable where the receipts were subject to tax deduction at source under section 195 of the Income-tax Act, 1961.

Issue (i): Whether the assessee's receipts from supervision, erection, and commissioning activities were taxable under section 44BBB of the Income-tax Act, 1961 or outside the scope of that provision and the relevant treaty provisions.

Analysis: The issue was decided by following the earlier year's view that the assessee had only performed supervision simpliciter and had not established that its activities amounted to the business of erection, assembly, testing, or commissioning. On that basis, the receipts were held not eligible for taxation under section 44BBB. The finding that the assessee had a permanent establishment in India was also upheld, and the business profits were treated as fees for technical services, with Article 7 of the DTAA read with sections 44D and 115A applied to the receipts.

Conclusion: The issue was decided against the assessee.

Issue (ii): Whether interest under section 234B of the Income-tax Act, 1961 was leviable where the receipts were subject to tax deduction at source under section 195 of the Income-tax Act, 1961.

Analysis: The receipts were found liable to tax deduction at source, and tax had in fact been deducted by the payer. Following the binding High Court decision referred to in the order, interest under section 234B was held not leviable on income so subject to deduction at source.

Conclusion: The issue was decided in favour of the assessee.

Final Conclusion: The appeal succeeded only on the interest question, while the substantive taxability challenge failed, resulting in partial relief to the assessee.

Ratio Decidendi: Where the payer is obliged to deduct tax at source on the relevant receipts, interest under section 234B is not leviable on the payee for failure to pay advance tax on that income.
