Treaty interest taxation and section 44BB nexus: refund interest linked to an Indian permanent establishment fell outside the treaty cap.

Interest effectively connected with a non-resident's permanent establishment in India falls outside the article 12(2) India-UK treaty cap, because article 12(6) displaces that limitation and brings the receipt within article 7 business profits. On the stated facts, refund interest arose from a debt-claim effectively connected with the Indian permanent establishment, so taxation as business profits was permissible. Separately, refund interest from the tax department does not satisfy section 44BB's nexus requirement, because it is not a receipt on account of oil-exploration services, facilities, or plant and machinery used for that activity. Accordingly, the treaty-rate argument and the section 44BB inclusion claim both failed.

Issues: (i) Whether interest received on refund was taxable only at 15% under article 12(2) of the India-UK treaty, or was excluded from that limitation by article 12(6) and taxable as business profits; (ii) Whether such interest could be included in the presumptive computation under section 44BB of the Income-tax Act, 1961.

Issue (i): Whether interest received on refund was taxable only at 15% under article 12(2) of the India-UK treaty, or was excluded from that limitation by article 12(6) and taxable as business profits.

Analysis: Article 12(2) permits taxation of interest in the source State subject to the 15% cap where the recipient is the beneficial owner and is resident in the other State. Article 12(6) withdraws the application of paragraphs (1) and (2) where the beneficial owner carries on business in the source State through a permanent establishment and the debt-claim is effectively connected with that permanent establishment. The assessee had a permanent establishment in India, and the refund interest arose from a debt-claim effectively connected with that establishment. In that situation, article 7 governing business profits applies, and the treaty rate limitation in article 12(2) does not govern the receipt.

Conclusion: The interest was not confined to taxation at 15% under article 12(2) and was rightly taxed as business profits. The issue is decided against the assessee.

Issue (ii): Whether such interest could be included in the presumptive computation under section 44BB of the Income-tax Act, 1961.

Analysis: Section 44BB deems 10% of specified receipts to be profits and gains of a non-resident engaged in specified oil exploration activities. The statutory receipts are amounts paid or payable on account of services and facilities connected with, or plant and machinery used in, prospecting for or extraction or production of mineral oils. Refund interest paid by the Income-tax Department does not answer that description, because it is not a receipt made on account of the provision of such services or facilities, nor on account of plant and machinery hired for that activity. The nexus required by section 44BB(2) is absent.

Conclusion: The refund interest could not be brought within section 44BB. The issue is decided against the assessee.

Final Conclusion: The treaty-based challenge to taxation at the higher business-profits rate failed, and the alternative claim for inclusion under section 44BB also failed. The appeals did not succeed.

Ratio Decidendi: Where interest is effectively connected with a non-resident's permanent establishment in India, article 12(6) of the India-UK treaty displaces the article 12(2) rate cap and permits taxation as business profits; and section 44BB applies only to receipts having the statutorily required nexus with oil-exploration services or facilities, not to refund interest from the tax department.
