Revenue expenditure, DTAA relief and proportionate interest: ITAT applies business nexus and treaty principles to mixed tax claims.

Expenditure on exploration, production, bidding and project-related travel was treated as revenue expenditure because it was integrally connected with the assessee's existing business, and the earlier view in its own case was followed. Lease-rental receipts representing principal repayment were held taxable where depreciation had already been allowed on the leased asset, with the assessee's alternative position kept open if depreciation is later disallowed. Branch profits of the Oman and Qatar operations were excluded from Indian taxation because they were attributable to a permanent establishment and had already been taxed in the source State under the relevant DTAA. Proportionate interest on borrowed funds used for the jetty was allowable where funds were intermingled and business use of the asset was established.

Issues: (i) whether expenditure incurred for exploration and production activities and for bidding and project-related travel was revenue expenditure, (ii) whether lease-rental receipts representing repayment of principal were taxable when depreciation on the leased asset had been allowed, (iii) whether profits of the Oman and Qatar branches were taxable in India despite the double tax avoidance agreements, and (iv) whether proportionate interest on borrowed funds used for the jetty was allowable.

Issue (i): whether expenditure incurred for exploration and production activities and for bidding and project-related travel was revenue expenditure.

Analysis: The expenditure was held to be part of the assessee's existing business activities and not a separate or preliminary venture. The activities were inter-linked with the ongoing business and the prior view in the assessee's own case, already approved by the High Court, was followed.

Conclusion: The expenditure was revenue in nature and the disallowance was not sustained, in favour of the assessee.

Issue (ii): whether lease-rental receipts representing repayment of principal were taxable when depreciation on the leased asset had been allowed.

Analysis: The claim for exclusion of principal repayment depended on the treatment of the lease transaction and the depreciation issue in the earlier year. Since depreciation had been allowed in the related year, the assessee's primary contention could not be accepted in the same form, though the assessee's alternative position was preserved if depreciation were later disallowed.

Conclusion: The revenue's ground was allowed on the footing that the principal amount formed part of taxable receipts at this stage, in favour of the revenue.

Issue (iii): whether profits of the Oman and Qatar branches were taxable in India despite the double tax avoidance agreements.

Analysis: The Tribunal applied the treaty provisions and the earlier decisions in the assessee's own case. It held that where the branch income was attributable to a permanent establishment and had already been subjected to tax in the source State, it could not again be brought to tax in India. The different wording in the Qatar treaty did not justify a different result.

Conclusion: The branch profits from Oman and Qatar were excluded from Indian taxation, in favour of the assessee.

Issue (iv): whether proportionate interest on borrowed funds used for the jetty was allowable.

Analysis: The source of funds used for the jetty could not be separately identified, the asset had been used in the business, and depreciation had already been allowed. On that basis, proportionate interest based on the ratio of own funds to borrowed funds was considered the proper method of allowance under the Act.

Conclusion: The proportionate interest claim was allowable, and the revenue's ground failed, in favour of the assessee.

Final Conclusion: The appeal succeeded only in part, with one issue decided for the revenue and the remaining substantive issues decided for the assessee.

Ratio Decidendi: Where business expenditure is integrally connected with an existing business, treaty provisions override the general charging provision to the extent of relief granted under a double tax avoidance agreement, and proportionate interest is allowable when borrowed and own funds are intermingled and the business use of the asset is established.
