ITAT Mumbai on Section 14A, Inter-Office Interest and Head Office Expenditure: Key Takeaways from DDIT Vs American Express Bank Ltd.

The Income Tax Appellate Tribunal, Mumbai Bench, in DDIT Vs American Express Bank Ltd. (ITA 5667/MUM/2004, order dated 08/10/2026, AY 2000-01) dealt with a wide range of issues relating to the Indian branch operations of American Express Bank Ltd., a foreign bank incorporated in the United States.

The decision addresses, among others, the following core questions:

• Whether Section 14A can be invoked in relation to:
  • Income taxed at a concessional rate under Section 115A, or
  • Receipts that are excluded from the ambit of “income” under the doctrine of mutuality.
• Tax treatment of inter-office interest between the Indian permanent establishment (PE) and the Head Office/overseas branches.
• Allowability of foreign exchange losses on revaluation of unmatured forward contracts.
• Applicability of Section 44C to various categories of Head Office expenses, including global system/data-processing charges.
• Deductibility of broken-period interest on securities held by a bank.
• Characterisation of Voluntary Retirement Scheme (VRS) payments as capital or revenue expenditure, in the context of a pre-Section 35DDA assessment year.

The Tribunal granted considerable relief on several issues and remanded the Head Office expenditure and global system charges to the Assessing Officer (AO) for a fresh factual exercise in light of subsequent Supreme Court guidance.

Preferential Tax Rate vs Exempt Income: Non-Applicability of Section 14A

Disallowance Against Income Taxed Under Section 115A

The assessee-bank had earned interest of ₹4,09,60,055 on foreign currency loans, chargeable to tax at 20% under Section 115A. The AO treated this stream of income as a separate segment and estimated an amount of ₹2,65,54,550 as expenditure attributable to earning such interest. That estimated figure was then disallowed against the assessee’s other business income.

Both the AO and the Commissioner of Income Tax (Appeals) [CIT(A)] proceeded on the footing that where a particular receipt is taxed at a concessional rate, some part of common expenditure must be ring-fenced and disallowed against normal business income.

The Tribunal disagreed and followed its own earlier orders in the assessee’s case for AYs 1998-99 and 1999-2000, which had already been affirmed by the Bombay High Court. The underlying principle reiterated is:

• Section 14A applies only where expenditure is incurred “in relation to income which does not form part of the total income”.
• A receipt that is fully taxable—albeit at a lower or special rate such as that prescribed in Section 115A—cannot be treated as “exempt” merely because of the rate structure.
• Once income is chargeable, Rajasthan State Warehousing Corporation principles on full deductibility without apportionment continue to hold.

On that basis, the Tribunal directed deletion of the entire ₹2,65,54,550 disallowance.

Inter-Office Interest: Not Taxable and Not “Exempt Income” for Section 14A

Interest on NOSTRO Accounts with Head Office and Overseas Branches

The assessee had both received and paid interest on NOSTRO accounts maintained with its Head Office and overseas branches. In the return and during assessment, the assessee argued that:

• Transactions between a foreign bank’s Head Office and its Indian branch are dealings within the same legal entity.
• Applying the principle of mutuality, the net interest of ₹13,09,03,922 received from Head Office/overseas branches was not taxable as income at all.

The CIT(A) accepted this proposition and treated the inter-office interest as non-taxable.

The Revenue challenged this finding, but the Tribunal upheld the CIT(A)’s conclusion. It followed:

• The Special Bench ruling in Sumitomo Mitsui Banking Corporation v. DDIT (2012) 19 taxmann.com 364, and
• J.P. Morgan Chase Bank, N.A. v. DCIT, ITA 9189/Mum/2004, order dated 10/10/2025 (Special Bench)

which both recognise that interest flows between a foreign bank’s Head Office and its Indian branch constitute self-to-self payments, not giving rise to taxable income under domestic law. Accordingly, the Revenue’s ground on taxability of ₹13,09,03,922 was dismissed.

Attempted Section 14A Disallowance on Inter-Office Interest

Having accepted that the inter-office interest receipt was not taxable, the CIT(A) nonetheless invoked Section 14A to disallow:

• Interest expenditure: ₹26,79,74,011
• Administrative/NRI marketing expenditure: ₹5,91,49,521

aggregating to ₹32,71,23,532, on the footing that these costs related to “exempt” income.

The Tribunal rejected this approach, relying on the Special Bench decision in J.P. Morgan Chase Bank, N.A. v. DCIT. That decision carefully distinguishes between:

• Income that is exempt under a specific provision of the Act but still within the broad concept of “income”, and
• Receipts that are not “income” at all, such as those excluded under the doctrine of mutuality.
