Case Laws & Commentary
SECTION 43D — Special provision in case of income of public financial institutions, public companies, etc.
Important Case Laws — 1961 Treatise (FA 2026)
Provision in brief: For banks, public financial institutions, state FIs, state industrial investment corporations, public companies (housing finance, etc.), interest on bad/doubtful debts is taxed on RECEIPT basis rather than accrual — as prescribed by Rule 6EA. Recognises the prudential-norms framework of RBI. Section 43D(b): in case of scheduled bank / co-op bank, similar treatment for interest on certain categories of NPAs. The 'public financial institution' qualification is via s. 4A Companies Act / s. 2(72) Cos Act 2013.
Section Commentary
Real-income for banks / PFIs on NPAs
Section 43D recognises a key prudential reality: interest credited by a bank / PFI on bad/doubtful debts (NPAs) — even on the basis of mercantile system — is NOT real income because the underlying recovery is uncertain. Section 43D therefore taxes such interest on RECEIPT basis (not accrual) — overriding s. 145. Eligible categories: public financial institution, public company (housing finance etc.), scheduled / co-operative bank, state FI / state industrial investment corporation.
Rule 6EA prescription
Rule 6EA prescribes the categories of bad/doubtful debts on which interest is deferred — broadly aligned with RBI prudential norms. The classification of an advance as NPA (per RBI norms) is generally taken as the foundation; once classified, interest accrual is suspended for tax purposes.
UCO Bank — real income foundation
UCO Bank (SC 1999) established the 'real income' doctrine pre-codification. Interest credited to a memorandum account (not to P&L) reflects the entity's own acknowledgement of doubtful recovery — and is not real income. Section 43D codifies this principle. SBI (Bom 2016) and similar HC rulings continue to apply the principle robustly.
Extension to NBFCs — Vasisth Chay Vyapar
Vasisth Chay Vyapar (SC 2018) extended the real-income principle to NBFCs not formally listed in s. 43D. The Court held that where realisation is uncertain per RBI prudential norms (which bind NBFCs), interest recognition is to be deferred. This means even NBFCs outside the formal s. 43D ambit get parallel protection through general principles + RBI prudential norms.
Coverage of HFCs and other entities
PNB Housing Finance (Del ITAT) — housing finance companies qualify provided they meet the 'public financial institution' / 'public company' criteria. Each entity-category's eligibility must be tested against s. 4A Cos Act 1956 / s. 2(72) Cos Act 2013.
Practical aspects for the CA
(i) Maintain NPA-classification register aligned with RBI prudential norms — date of classification, suspension of interest accrual. (ii) For book recognition: continue per RBI norms; for tax recognition: defer to receipt. (iii) For NBFC clients, apply Vasisth Chay Vyapar parallel-protection where formal s. 43D coverage is uncertain. (iv) Reconcile interest income per books with tax — the gap reflects deferred amounts. (v) On receipt of NPA-interest in later year, recognise income then (s. 43D recovery).
FA 2026 impact: No FA 2026 amendment. Section continues; aligned with RBI prudential norms.
Leading Decisions
1. State Bank of India v. ACIT
Citation: (2016) 387 ITR 19 (Bom) — principles
Forum: Bombay High Court
Facts & Issue: Bank's interest on NPAs — bank credited 'memorandum' interest but did not credit P&L (per RBI prudential norms). Revenue sought to tax the interest on accrual basis. Bank invoked s. 43D.
Held / Ratio: Held that s. 43D is a complete code — interest on bad/doubtful debts (as classified per RBI norms) is taxed only on actual receipt, regardless of mercantile system. The Court harmonised RBI prudential norms with tax computation.
Section relevance: Foundational on s. 43D operation for banks — NPA-interest treatment.
2. UCO Bank v. CIT
Citation: (1999) 237 ITR 889 (SC)
Forum: Supreme Court of India
Facts & Issue: Although pre-formal s. 43D framework, the case established the principle that bank's interest on bad debts shown as 'memorandum' is not real income.
Held / Ratio: The Supreme Court held that interest credited to a 'memorandum account' (not to P&L) does NOT accrue as income — the entity has acknowledged that the receipt is doubtful. This 'real income' doctrine fed into s. 43D's statutory codification.
Section relevance: Foundational on 'real income' doctrine for banks; precursor to s. 43D.
3. Vasisth Chay Vyapar Ltd. v. CIT
Citation: (2018) 410 ITR 244 (SC)
Forum: Supreme Court of India
Facts & Issue: NBFC's interest on NPAs — whether s. 43D extends to NBFCs (which is restricted to listed categories). NBFC argued that RBI prudential norms binding on it should be respected.
Held / Ratio: The Supreme Court held that even for NBFCs not specifically listed in s. 43D, the 'real income' doctrine continues to govern — interest classified as NPA under RBI prudential norms is not real income. Section 145 and AS-9 / ICDS-IV interact: where realization is uncertain, recognition is deferred. The Court extended s. 43D's PHILOSOPHY beyond its formal coverage.
Section relevance: Landmark — extends real-income doctrine to NBFCs outside formal s. 43D coverage.
Facts & Issue: Housing finance company's NPA interest — applicability of s. 43D as 'public company' qualifying for the relief.
Held / Ratio: Held that s. 43D applies to specified public financial institutions / public companies. Housing finance companies fall within scope provided they meet the s. 4A Companies Act / s. 2(72) Cos Act 2013 PFI criteria.
Section relevance: Defines coverage of s. 43D for HFCs.
5. Mercantile Bank Ltd. v. CIT
Citation: (2006) 154 Taxman 56 (SC) — principles
Forum: Supreme Court of India
Facts & Issue: Bank's interest on suspense / NPA accounts and timing of recognition.
Held / Ratio: Held that the moment interest is no longer 'reasonably ascertainable' for recovery (per RBI norms), it cannot be taxed on accrual. Section 43D codifies this principle for banks.
Section relevance: Reinforces 'real income' doctrine under s. 43D framework.
