Treaty rate on interest and no surcharge or cess where PE attribution is not established under the DTAA.

Interest on suppliers' credit under the India-Japan DTAA remained taxable at the concessional treaty rate because Article 11(6) applies only where the debt-claim is directly or indirectly attributable to a permanent establishment; mere existence of a PE and a general business nexus was insufficient. The record did not show effective connection with the PE, so Article 11(2) continued to govern. Surcharge and health and education cess could not be added to income taxed at the treaty-prescribed rate, as the DTAA rate controlled the full tax burden. Relief was therefore granted on surcharge and cess, while treaty-rate taxation on interest was sustained.

Issues: (i) Whether interest on suppliers' credit was taxable at the concessional rate under Article 11(2) of the India-Japan DTAA or whether Article 11(6) read with Article 7 applied because of the assessee's permanent establishment in India; (ii) Whether surcharge and health and education cess could be levied on income taxable at the treaty rate.

Issue (i): Whether interest on suppliers' credit was taxable at the concessional rate under Article 11(2) of the India-Japan DTAA or whether Article 11(6) read with Article 7 applied because of the assessee's permanent establishment in India.

Analysis: Article 11(2) provides for source taxation of interest at a capped gross rate, while Article 11(6) displaces that regime only when the beneficial owner carries on business in the source State through a permanent establishment and the relevant debt-claim is effectively connected with that permanent establishment. Mere existence of a permanent establishment is insufficient. The connection must be such that the interest is directly or indirectly attributable to the permanent establishment and therefore taxable under Article 7(1). On the facts, no material was shown to establish that the suppliers' credit or the resulting interest income was so attributable; the record showed only the existence of a permanent establishment and a general nexus, which was not enough to trigger the exclusion clause.

Conclusion: The interest income remained taxable under Article 11(2), and the challenge based on Article 11(6) failed against the assessee.

Issue (ii): Whether surcharge and health and education cess could be levied on income taxable at the treaty rate.

Analysis: The treaty-restricted rate was held to govern the tax charge on the relevant income. Once the income is taxed under the DTAA at a specified rate, the levy cannot be enlarged by adding surcharge and cess in a manner inconsistent with the treaty limitation. The Tribunal followed its earlier coordinate-bench view that treaty taxation at the prescribed rate controls the full tax burden on such income.

Conclusion: Levy of surcharge and health and education cess was not sustainable, and the issue was decided in favour of the assessee.

Final Conclusion: The Revenue's appeal failed, while the assessee obtained relief on the cess and surcharge question; the assessment was sustained only to the extent consistent with the treaty rate on interest income.

Ratio Decidendi: Under Article 11(6), exclusion of the concessional interest article is triggered only when the interest is shown to be directly or indirectly attributable to the permanent establishment, and treaty-capped taxation cannot be expanded by surcharge or cess contrary to the applicable DTAA rate.
