Treaty taxation of shipping income and refund interest: residuary article applied, PE connection failed, and section 234B interest was denied.

Shipping profits from the operation of ships in international traffic were treated as falling under the residuary treaty article for income not otherwise dealt with, so section 44B could not override the more beneficial India-Switzerland treaty rule. A permanent establishment in India was recognised on the agency facts, but the ships were not shown to be effectively connected with that establishment, so Article 7 did not apply. Interest on income-tax refund was classified as interest income under the treaty's interest article, not as business profits. Interest under section 234B was held not leviable where tax was deductible at source and treaty protection applied.

Issues: (i) Whether profits from the operation of ships in international traffic were taxable in India under section 44B of the Income-tax Act, 1961 or were governed by Article 22 of the Double Taxation Avoidance Agreement between India and Switzerland; (ii) Whether the Indian agent constituted a permanent establishment and whether the ships were effectively connected with that permanent establishment so as to attract Article 7; (iii) Whether interest on income-tax refund was taxable under Article 11 or Article 7 of the Double Taxation Avoidance Agreement between India and Switzerland; (iv) Whether interest under section 234B of the Income-tax Act, 1961 was leviable.

Issue (i): Whether profits from the operation of ships in international traffic were taxable in India under section 44B of the Income-tax Act, 1961 or were governed by Article 22 of the Double Taxation Avoidance Agreement between India and Switzerland.

Analysis: Article 22 is the residuary provision covering income of a resident not dealt with in the foregoing articles. The shipping profits were held not to be dealt with by the exclusionary language of Article 7, because mere exclusion from Article 7 did not amount to specific treatment of that income under the treaty. The competent authorities of India and Switzerland had also understood Article 22 to cover such shipping income, and that common understanding supported treaty-based taxation only in the State of residence. The domestic provision in section 44B could not prevail over the more beneficial treaty rule.

Conclusion: The issue was decided in favour of the assessee. The shipping profits were held taxable only under Article 22 and not in India under section 44B.

Issue (ii): Whether the Indian agent constituted a permanent establishment and whether the ships were effectively connected with that permanent establishment so as to attract Article 7.

Analysis: The agency agreement showed legally and economically dependent agency functions, supporting the existence of a permanent establishment in India. However, Article 22(2) withdraws the residuary exemption only where the income-generating right or property is effectively connected with the permanent establishment. The ships themselves remained assets of the non-resident shipping company and were not shown to be effectively connected with the Indian agency establishment. Therefore, the conditions for shifting the income to Article 7 were not satisfied.

Conclusion: The issue was decided in favour of the assessee. Although a permanent establishment was found, the shipping income was not brought within Article 7 because the ships were not effectively connected with that permanent establishment.

Issue (iii): Whether interest on income-tax refund was taxable under Article 11 or Article 7 of the Double Taxation Avoidance Agreement between India and Switzerland.

Analysis: The refund interest was treated as interest income falling within the treaty provision specifically dealing with interest, rather than as business profits connected with the permanent establishment. The special bench authority followed on this point supported taxation of the refund interest under the interest article at the treaty rate.

Conclusion: The issue was decided against the Revenue and in favour of the assessee. The refund interest was held taxable under Article 11.

Issue (iv): Whether interest under section 234B of the Income-tax Act, 1961 was leviable.

Analysis: The levy was covered by binding precedent that where tax was deductible at source and the non-resident's income was otherwise governed by treaty protection, advance-tax default interest could not be sustained in the manner sought by the Revenue.

Conclusion: The issue was decided in favour of the assessee. Interest under section 234B was not leviable.

Final Conclusion: The assessee's shipping income remained outside Indian taxation under the applicable treaty, the PE contention did not alter that result, and the ancillary dispute on refund interest and advance-tax interest was also resolved against the Revenue.

Ratio Decidendi: Where a tax treaty contains a residuary article covering income not dealt with elsewhere, mere exclusion of an item from another article does not amount to its being dealt with under that article; such income falls under the residuary article unless it is effectively connected with a permanent establishment in the source State.
