Issue (i): Eligibility of the National Long Distance undertaking for deduction under section 80-IA and sufficiency of Form 10CCB certified by an independent Chartered Accountant.
Analysis: Section 80-IA(4)(ii) requires examination of the identifiable undertaking carrying on the specified telecommunication activity rather than the assessee-company's entire business. The National Long Distance activity arose under a separate licence, employed a separately identifiable network, infrastructure and personnel, generated separately ascertainable revenue and expenditure, and constituted a commercial unit distinct from the pre-existing international long-distance operations. Section 80-IA(7), read with section 288 and Rule 18BBB, requires audit by an accountant and does not require certification exclusively by the statutory auditor of the company.
Conclusion: The National Long Distance activity is an independent eligible undertaking, and Form 10CCB certified by an independent Chartered Accountant satisfies the audit requirement; the deduction claim is in favour of the assessee, subject to fulfilment of the remaining statutory conditions.
Issue (ii): Classification of the Gateway Digital Switch system for depreciation and consequential computation of its written-down value.
Analysis: The Gateway Digital Switch performed signal processing, routing, storage, logical operations and call-control functions through processors, memory and programmed software. Its switching operations were integrated with the computer architecture and could not be viewed merely as those of an independent specialised machine. The functional integration test applicable to computer hardware was satisfied. The opening written-down value nevertheless required verification with reference to depreciation actually allowed in intervening years.
Conclusion: The Gateway Digital Switch falls within the computer block and is eligible for depreciation at 60%; consequential written-down-value computation is to be verified by the Assessing Officer. The issue is in favour of the assessee.
Issue (iii): Allowability of depreciation on Iridium assets forming part of an existing block of plant and machinery.
Analysis: Once assets enter an existing block, depreciation is governed by the block-of-assets mechanism under sections 32 and 43(6). Book impairment and technological obsolescence do not reduce the tax written-down value unless a statutory adjustment, including moneys payable on sale, discard, demolition or destruction, is established. The impairment loss was added back and did not result in double deduction; the relevant block continued to be used for business.
Conclusion: Depreciation on the Iridium assets as part of the plant-and-machinery block is allowable after verification of the written-down value under section 43(6). The issue is in favour of the assessee.
Issue (iv): Characterisation of interest from temporary short-term deposits of business funds.
Analysis: The short-term deposits represented temporarily available business funds managed through treasury and cash-management operations while substantial business and contingent liabilities remained outstanding. No material established that the funds were permanently surplus or segregated from the business. The deposits retained a direct business nexus and were not an independent investment activity.
Conclusion: Interest from the short-term deposits is assessable under the head profits and gains of business or profession, in favour of the assessee.
Issue (v): Additional disallowance under section 14A read with Rule 8D where no exempt income was earned.
Analysis: The assessee had voluntarily disallowed expenditure under section 14A in its return and did not establish that its own computation was factually erroneous. However, in the absence of exempt income during the relevant year, an additional disallowance under Rule 8D could not be sustained merely by mechanical application of that Rule.
Conclusion: The voluntary disallowance is sustained, but the additional disallowance under section 14A read with Rule 8D is deleted; the issue is partly in favour of the assessee.
Issue (vi): Allowability of depreciation on payments to MMRDA for commercial-use rights and on the related lease-premium block.
Analysis: The payments secured rights to commercially use the leased premises and were capital in nature. The restriction on an Assessing Officer entertaining a new claim without a revised return does not limit appellate jurisdiction. Consistent treatment of identical MMRDA payments required their inclusion in the relevant depreciable block. Written-down value must be computed after reducing only depreciation actually allowed in intervening years, and not notional depreciation.
Conclusion: Depreciation on the commercial-use rights and consequential depreciation on the relevant lease-premium block are allowable after verification of the correct written-down value. The issue is in favour of the assessee.
Issue (vii): Entitlement to TDS credit supported by physical certificates and arising from an amalgamation.
Analysis: TDS credit cannot be denied solely because the deduction is absent from Form 26AS where the deduction is otherwise substantiated by valid physical certificates. Credit relating to a transferor company may also be available to the amalgamated company, subject to verification of the merger documents, certificates and reconciliation.
Conclusion: The claim for admissible TDS credit is to be verified and granted in accordance with law; the issue is in favour of the assessee subject to factual verification.
Issue (viii): Computation of interest under section 234D on excess refund.
Analysis: The applicable settled computation requires distinct treatment of the tax element and the interest component of a prior refund. The impugned computation was not consistent with the binding method applied in the assessee's earlier years.
Conclusion: Interest under section 234D shall be recomputed in accordance with the settled method governing excess refund. The issue is in favour of the assessee.
Issue (ix): Entitlement to interest under section 244A until actual grant of refund.
Analysis: Statutory interest on a refund cannot end merely upon determination of the refund or passing of an order giving effect. The entitlement continues until the refund is actually paid or credited, including a refund arising upon appellate effect.
Conclusion: Interest under section 244A is payable up to the date of actual payment or grant of the refund. The issue is in favour of the assessee.
Issue (x): Depreciation on goodwill arising from acquisition of an Internet Service Provider business.
Analysis: Consideration paid in excess of identifiable net assets for acquisition of a business represents goodwill and falls within the expression any other business or commercial rights of similar nature under section 32(1)(ii). No material established that the acquired goodwill was outside this statutory category.
Conclusion: Goodwill arising from the business acquisition is a depreciable intangible asset under section 32(1)(ii); the disallowance is deleted in favour of the assessee.
Issue (xi): Arm's-length guarantee-commission rate for corporate guarantees to associated enterprises.
Analysis: The higher rates adopted by the transfer-pricing authorities were unsupported by comparable transactions or a reasoned benchmarking exercise. A rate of 0.33% accepted for substantially similar corporate-guarantee transactions of the same assessee in a subsequent year provided the appropriate benchmark, no material change in economic circumstances having been shown.
Conclusion: Corporate guarantee commission shall be benchmarked at 0.33%; the issue is partly in favour of the assessee.
Issue (xii): Arm's-length interest on USD-denominated loans to associated enterprises.
Analysis: Foreign-currency loans must be benchmarked by reference to the currency of denomination. The assessee's rate of LIBOR plus 1.75% was supported by internal foreign-currency borrowing comparables, external uncontrolled transactions and acceptance of the same rate for similar transactions in the succeeding year. Domestic rupee borrowing costs could not replace the currency-specific benchmark.
Conclusion: Interest charged at LIBOR plus 1.75% is at arm's length and the adjustment is deleted, in favour of the assessee.
Issue (xiii): Arm's-length fees for Letters of Comfort and a Letter of Support.
Analysis: The rates of 1.5% adopted by the Transfer Pricing Officer and 0.75% retained by the DRP lacked support from comparable uncontrolled transactions or an independent benchmarking exercise. Although not directly applicable to the year, the 0.20% rate agreed under the subsequent APA was relevant corroborative material for substantially similar Letters of Comfort. In the peculiar facts, that rate was also adopted for the Letter of Support to bring finality to the dispute.
Conclusion: Fees for both the Letters of Comfort and the Letter of Support shall be recomputed at 0.20%, after credit for any fee already charged; the issue is partly in favour of the assessee.
Issue (xiv): Transfer-pricing adjustment on overdue receivables and recoverable advances.
Analysis: Comparable delayed receivables from non-associated customers did not carry interest and therefore constituted an internal comparable uncontrolled price. The assessee had nevertheless charged associated enterprises interest at LIBOR plus 1.75%, which was more onerous than the terms extended to independent customers.
Conclusion: The interest charged on overdue receivables and recoverable advances is at arm's length, and the further adjustment is deleted in favour of the assessee.
Final Conclusion: The eligible deduction, depreciation claims, business-income characterisation and refund-related reliefs shall be given effect in accordance with these findings, while transfer-pricing additions are confined to the specified arm's-length rates and the limited factual verifications directed.
Deduction for National Long Distance telecommunication undertaking - Audit certification of eligible undertaking accounts - Depreciation on computer-integrated Gateway Digital Switch - Block-of-assets depreciation despite technological obsolescence - Interest from temporary deployment of business funds - Disallowance relating to exempt income in absence of exempt income - Depreciation on commercial user rights in leased land - Depreciation on acquired goodwill - Interest on refund until actual payment - Arm's length corporate guarantee commission - Arm's length interest on foreign currency loans to associated enterprises - Arm's length fees for letters of comfort and letters of support - Transfer pricing of overdue associated enterprise receivables Deduction for National Long Distance telecommunication undertaking - Independent undertaking - Eligibility of the National Long Distance telecommunication activity for deduction as an independent undertaking - HELD THAT: - An undertaking is distinct from the company owning it, and an activity does not lose its identity merely because it is conducted in the same broad line of business or interfaces with other networks. The National Long Distance activity was established under a separate licence, supported by newly created and identifiable network infrastructure, dedicated resources, separately ascertainable revenue and expenditure, and constituted a commercially identifiable unit. Unlike an earth station constituting an internal component of the pre-existing international transmission system, the entire National Long Distance activity was a separate undertaking. [Paras 7] The National Long Distance undertaking was held eligible for deduction, subject to fulfilment of the other statutory conditions. Audit certification of eligible undertaking accounts - Form No. 10CCB - Validity of the audit report for the eligible National Long Distance undertaking when certified by an independent Chartered Accountant rather than the statutory auditor - HELD THAT: - The statutory requirement is audit of the eligible undertaking's accounts by an accountant in the prescribed form. It does not require that the prescribed report must be issued by the statutory auditor of the company. A separate Form No. 10CCB certified by an independent Chartered Accountant for the undertaking satisfied the requirement. [Paras 7] The audit certification could not be rejected merely because it was not issued by the statutory auditor of the assessee. Depreciation on computer-integrated Gateway Digital Switch - Functional test for computer hardware - Classification of the Gateway Digital Switch as a computer block asset rather than plant and machinery for depreciation - HELD THAT: - The Gateway Digital Switch operated through computer-controlled processing, processors, memory and programmed instructions for routing telecommunication calls. Its switching functions were integrated with the computer architecture and software and could not be viewed in isolation. Its specialised purpose did not exclude it from the computer block where it functioned as an integral computer-controlled component. [Paras 9] The Gateway Digital Switch was held eligible for depreciation at the rate applicable to computers; computation of the opening written down value and consequential depreciation was remitted to the Assessing Officer. Block-of-assets depreciation despite technological obsolescence - Tax written down value - Allowability of depreciation on technologically obsolete Iridium assets forming part of the existing plant and machinery block - HELD THAT: - Once assets enter an existing block, depreciation is determined with reference to the block rather than each individual asset. Book impairment did not reduce the tax written down value where it had not been allowed as a tax deduction and no moneys payable on discard or obsolescence were established. Non-use of the individual assets due to technological obsolescence did not disentitle depreciation where the block continued to be used for business. [Paras 12] Depreciation on the relevant plant and machinery block was allowable, subject to verification of the written down value in accordance with law. Interest from temporary deployment of business funds - Business income - Head of income for interest earned on short-term bank deposits made out of temporarily available business funds - HELD THAT: - The character of interest depends on the purpose and character of the deposited funds, not merely on the immediate source of the receipt. The deposits represented temporary deployment of circulating business funds pending business use and were managed through the regular treasury and cash-management functions. The Revenue did not establish that the funds were permanently segregated surplus funds or constituted an independent investment activity. [Paras 14] The interest income was directed to be assessed under the head profits and gains of business or profession. Disallowance relating to exempt income in absence of exempt income - Voluntary disallowance - Sustainability of a further disallowance under section 14A and Rule 8D where no exempt income was earned, despite a voluntary disallowance in the return - HELD THAT: - The amount voluntarily disallowed after examination of the accounts could not be withdrawn merely because subsequent judicial developments supported the proposition that no disallowance is warranted in the absence of exempt income; the assessee had not shown that its own computation was factually erroneous. However, a further disallowance under Rule 8D could not be made automatically where no exempt income was earned during the relevant year. [Paras 16] The voluntary disallowance was sustained, while the additional disallowance under section 14A read with Rule 8D was deleted. Depreciation on commercial user rights in leased land - Appellate power to entertain additional claim - Depreciation on payment made for changing the permitted use of leased land from residential to commercial use - HELD THAT: - The restriction on the Assessing Officer entertaining a fresh claim otherwise than through a revised return does not curtail the Tribunal's appellate powers. The payment was made for commercial user rights obtained from the development authority and was not to be equated simpliciter with the cost of land. Consistently with the treatment of an identical payment in the assessee's earlier case, the expenditure was to be capitalised in the relevant block for depreciation. [Paras 18] Depreciation was directed to be allowed after verification of the written down value, calculated with reference to depreciation actually allowed in preceding years. Tax deduction at source credit on physical certificates and merger - Grant of tax deduction at source credit supported by physical certificates and credit relating to the amalgamating company - HELD THAT: - Tax deduction at source credit cannot be denied solely because it is not reflected in Form 26AS where deduction is otherwise established through the relevant certificates. The physical certificates, merger-related credit and reconciliation required factual verification. [Paras 20] The matter was remitted to the Assessing Officer for verification and grant of admissible tax deduction at source credit in accordance with law. Interest for default in payment of advance tax after modified return - Computation of interest under section 234B after a modified return filed pursuant to an Advance Pricing Agreement - HELD THAT: - The interest computation required consequential adjustment after giving effect to the return filed pursuant to the Advance Pricing Agreement. [Paras 21] The Assessing Officer was directed to delete or recompute interest under section 234B in accordance with law after giving effect to the modified return. Interest on excess refund - Treatment of earlier refund interest - Treatment of interest earlier granted under section 244A while computing interest under section 234D - HELD THAT: - Following the earlier order in the assessee's own case for A.Y. 2004-05 and the High Court affirmation [2019 (3) TMI 2117 - BOMBAY HIGH COURT] recorded therein, the Tribunal directed recomputation on the stated basis. [Paras 23] The Assessing Officer was directed to compute interest under section 234D including the interest granted under section 244A. Interest on refund until actual payment - Period for grant of statutory interest on refunds arising under section 244A - HELD THAT: - The issue is squarely covered by the decision of Tata Sons Pvt. Ltd. [2023 (12) TMI 875 - ITAT MUMBAI] and, more importantly, by the subsequent decision in Capgemini Technology Services India Ltd. [2025 (12) TMI 1181 - BOMBAY HIGH COURT] The principle that emerges is that the statutory interest u/s. 244A cannot be curtailed merely because the refund has been determined on an earlier date; the assessee is entitled to such interest up to the date on which the refund is actually paid/credited. We, therefore, direct the Ld. AO to recompute and grant interest u/s. 244A of the Act up to the date of actual payment/receipt of refund by the assessee, in accordance with law. [Paras 24, 26] The Assessing Officer was directed to grant interest under section 244A up to the date of actual payment or grant of the refund. Consequential depreciation on initial lease premium - Consequential depreciation on the initial premium paid for leasehold rights - HELD THAT: - The claim was consequential to the earlier order in the assessee's own case. Determination of the correct written down value depended upon verification of the prior order and the depreciation actually allowed in preceding years. [Paras 26] The matter was remitted to the Assessing Officer to verify the computation and allow consequential depreciation to the extent admissible in accordance with law. Depreciation on acquired goodwill - Business or commercial rights - Allowability of depreciation on goodwill arising from acquisition of a business undertaking - HELD THAT: - Goodwill falls within the expression any other business or commercial right of similar nature and is an intangible asset eligible for depreciation. The Revenue did not show that the goodwill arising from the business acquisition was different in character or otherwise outside the statutory provision. We find that the issue stands squarely covered by the decision of Smifs Securities Ltd. [2012 (8) TMI 713 - SUPREME COURT] wherein considered the scope of the expression “any other business or commercial rights of similar nature” occurring in section 32(1)(ii) and held that goodwill falls within the ambit of the said expression and is therefore an intangible asset eligible for depreciation under section 32 of the Act. The Hon'ble Supreme Court also accepted the principle that goodwill arising on amalgamation constitutes an asset within the meaning of section 32(1)(ii). [Para 27] The disallowance of depreciation on goodwill was deleted. Arm's length corporate guarantee commission - Consistency in transfer pricing - Arm's length guarantee commission for corporate guarantees furnished to associated enterprises - HELD THAT: - The additional risk mark-up adopted by the Transfer Pricing Officer and the rate retained by the Dispute Resolution Panel were unsupported by identified comparable transactions or an independent benchmarking exercise. The rate accepted in the assessee's own substantially similar guarantee transactions in a subsequent year was relevant material, and the Revenue established no material difference in the functional or economic circumstances. [Paras 31] The guarantee commission was directed to be benchmarked at 0.33%. Arm's length interest on foreign currency loans to associated enterprises - Currency-specific benchmarking - Arm's length interest on United States dollar denominated loans advanced to associated enterprises - HELD THAT: - Interest on a foreign currency loan must be benchmarked by reference to the currency of denomination. The domestic borrowing cost in Indian currency was not an appropriate substitute. The rate charged was corroborated by the assessee's foreign currency borrowings, uncontrolled comparable loans and its acceptance by the Transfer Pricing Officer in the succeeding year for similar transactions. [Paras 32] Interest charged at LIBOR plus 1.75% was held to be at arm's length. Arm's length fees for letters of comfort and letters of support - Arm's length fee for letters of comfort and a letter of support issued in favour of associated enterprises - HELD THAT: - The characterisation of the instruments as international transactions was not pressed for adjudication. The rates adopted by the Transfer Pricing Officer and the Dispute Resolution Panel lacked support from comparable uncontrolled transactions or a reasoned benchmarking exercise. The subsequently agreed Advance Pricing Agreement rate for letters of comfort was relevant corroborative material in the absence of a demonstrated material difference in circumstances. The same rate for the letter of support was adopted only to bring finality to the dispute on the peculiar facts of the year. [Paras 34] The arm's length fee for both the letters of comfort and the letter of support was directed to be recomputed at 0.20%, with credit for any fee already charged. Transfer pricing of overdue associated enterprise receivables - Internal comparable uncontrolled price - Arm's length interest on overdue receivables and recoverable advances from associated enterprises - HELD THAT: - Comparable delayed receivables from non-associated enterprises bore no interest and therefore constituted a direct internal comparable. Since the assessee had charged associated enterprises interest at LIBOR plus 1.75%, on terms more onerous than those extended to non-associated enterprises, the charge was at arm's length. [Paras 35] The further transfer pricing adjustment on overdue receivables was deleted. Final Conclusion: The assessee's appeal was partly allowed, with substantive relief on deduction, depreciation, income characterisation and transfer-pricing issues, and specified matters remitted for verification or recomputation. The Revenue's appeal was partly allowed consequentially.
