Bank taxation principle: RBI prudential norms and banking business treatment override general disallowance rules, resulting in deletions.

For a banking assessee the Tribunal applied banking-specific accounting and regulatory principles, holding that broken period interest on trading securities is revenue in nature and its disallowance is deleted; adjustments under the anti-exemption framework and apportionment rule are not to be mechanically applied to banks where investments form part of business, so section 14A/Rule 8D disallowances (including for book profit under the corporate tax code) are deleted; amortisation of HTM premium is allowable; interest on perpetual debt instruments treated as borrowings is deductible; certain wage-arrear provisions are allowable under the mercantile rule; unrealised NPA interest recognition follows prudential norms; year-end provisions and tax on non-monetary perquisites are not disallowed for normal income or book profit.

Issues: (i) Whether the assessing officer was justified in disallowing broken period interest; (ii) Whether disallowance under section 14A read with Rule 8D (for normal computation and for computing book profit under section 115JB) was correctly sustained; (iii) Whether amortisation of premium on HTM securities is disallowable; (iv) Whether interest on Innovative Perpetual Debt Instruments (IPDI) is disallowable as not being interest on borrowing; (v) Whether provisions for estimated wage arrears under section 43B were rightly disallowed; (vi) Whether unrealised interest on advances classified as NPA (recognised per RBI prudential norms) is taxable; (vii) Whether year-end provisions for expenses (reversed next year) and tax on non-monetary perquisites are to be disallowed for normal computation and for book profit under section 115JB.

Issue (i): Disallowance of broken period interest by the AO.

Analysis: The Tribunal examined the factual position and precedent authorities, including the Bombay High Court decision in CIT v. State Bank of India and American Express International Banking, distinguishing Vijaya Bank where the facts and head of income differed. The Tribunal found the securities were trading assets/business receipts and that the accounting/tax treatment did not warrant treating broken period interest as capital outlay in the assessee's facts.

Conclusion: Held in favour of the assessee; the disallowance of broken period interest is deleted.

Issue (ii): Disallowance under section 14A read with Rule 8D for normal income computation and for book profit under section 115JB.

Analysis: The Tribunal followed coordinate-bench and High Court/Supreme Court guidance (including Maxopp and consequent CBDT circular) and earlier Tribunal decisions in the assessee's own case. It considered the banking context, the sufficiency of own funds, and precedents holding that 14A disallowance and Rule 8D adjustments are not to be applied in the same manner to banks where investments form part of business activity; it also addressed the Rule 8D apportionment tests applied by earlier benches.

Conclusion: Held in favour of the assessee; the disallowance under section 14A read with Rule 8D (both for normal computation and for computation of book profit under section 115JB) is deleted.

Issue (iii): Disallowance of amortisation of premium on HTM securities.

Analysis: The Tribunal reviewed RBI accounting treatment and multiple prior decisions of the Tribunal and the Bombay High Court in the assessee's own case and co-ordinate matters, which consistently treated amortisation of premium on HTM securities as acceptable for the banking assessee on the facts presented.

Conclusion: Held in favour of the assessee; the disallowance of amortisation of premium on HTM securities is deleted.

Issue (iv): Disallowance of interest on Innovative Perpetual Debt Instruments (IPDI).

Analysis: The Tribunal examined the terms and documentary evidence of issuance, the fixed interest obligation, treatment in financial statements (shown under borrowings and charged to profit and loss), instances of redemption, and distinguishing authorities where capital was attributable to government/statutory arrangements. Coordinate-bench decisions treating similar perpetual instruments as borrowings for tax deduction purposes were followed.

Conclusion: Held in favour of the assessee; interest on IPDI is allowable as interest on borrowing and the disallowance is deleted.

Issue (v): Disallowance of estimated wage-arrear provisions under section 43B (assessee's appeal ground).

Analysis: The Tribunal applied its prior decisions in the assessee's own case and other coordinate-bench authority considering the nature of provisions, statutory timing for payment, and precedents holding that certain employee-related provisions are not disallowable under section 43B where not statutorily payable in the accounting year.

Conclusion: Held in favour of the assessee; the disallowance under section 43B is deleted.

Issue (vi): Taxation of unrealised interest on advances classified as NPA (recognition period per RBI vs rule 6EA).

Analysis: The Tribunal considered section 43D, RBI prudential norms reducing NPA classification to 90 days, Rule 6EA/RBI rule interplay and relevant precedents (including coordinate-bench decisions). It held that for scheduled banks/RBI-regulated entities, income recognition must be read with RBI guidelines as reflected in section 43D, and therefore the AO could not substitute a longer recognition period contrary to RBI norms.

Conclusion: Held in favour of the assessee; the assessee's contention on non-recognition/assessment of unrealised interest in the year is accepted and the disallowance is reversed.

Issue (vii): Disallowance of year-end provisions for expenses (reversed next year) and tax on non-monetary perquisites in computing normal income and book profit under section 115JB.

Analysis: Following Tribunal and High Court precedents, the Tribunal accepted that properly made year-end provisions (subsequently crystallised and subjected to TDS when charged) are allowable on mercantile basis; for book profit under section 115JB the Tribunal applied the statutory computation code and relevant decisions addressing whether tax on non-monetary perquisites falls within the definition of income-tax to be added back.

Conclusion: Held in favour of the assessee; the year-end provisions (reversed next year) and the tax on non-monetary perquisites are not required to be disallowed as determined by the CIT(A) and applicable precedents.

Final Conclusion: On the matters substantively argued and reasoned, the Tribunal upheld the first-instance appellate conclusions that favoured the assessee across the contested issues (broken period interest, section 14A/Rule 8D disallowances, HTM premium amortisation, IPDI interest, certain section 43B provisions, NPA interest recognition, and year end provisions/book profit adjustments), resulting in dismissal of the revenue's appeal and partial allowance of the assessee's appeal on specified grounds; ancillary or not-pressed grounds were not adjudicated.

Ratio Decidendi: Where bank-specific facts and RBI prudential norms govern recognition and classification of securities and interest, those regulatory norms and consistent precedents governing banking businesses prevail for tax treatment; consequently, disallowances premised on general anti exemption rules or on characterising bank-held securities/ instruments as capital rather than business items are not sustainable absent distinguishing facts.
