HISTORICAL CONTEXT
Section 37(1) is the general residual deduction provision for PGBP. Triple test: (a) NOT covered under sections 30-36 (specific deductions); (b) NOT capital expenditure (revenue character); (c) NOT personal expenses; (d) Wholly + exclusively for business / profession. The 'wholly and exclusively' standard is operationally strict — must be SOLELY for business; mixed-purpose expenses require apportionment.
Explanation 1 — illegal / prohibited expenditure disallowed (Apex Laboratories SC 2022 anchor for freebies to doctors). Explanation 2 — CSR expenditure under Companies Act s. 135 NOT deductible. Explanation 3 (FA 2022) — extended illegality framework: includes (a) offences under Indian or FOREIGN law; (b) benefits to persons in violation of any law / rule / regulation.
Practitioner significance — comprehensive scope but rigorous standard. Common expenditures: rent / utilities / professional fees / travel / advertisement / marketing / commissions / customer entertainment (with vigilance) / employee welfare / legal expenses. Capital-vs-revenue characterisation often litigated. Section 14A — disallowance for exempt-income-earning expenditure (Maxopp framework).
The transition to the Income-tax Act, 2025 preserves the PGBP framework.
FINANCE ACT AMENDMENT TIMELINE
■ FA 1962 — Section 37 came into force.
■ FA 1998 — Explanation 1 (illegal expenditure).
■ FA 2014 — Explanation 2 (CSR disallowance).
■ FA 2022 — Explanation 3 (extended illegality framework).
■ Apex Laboratories (SC 2022) — Doctor freebies disallowance.
Facts. The Department sought to apply a surcharge provision retrospectively to block-period assessments. The assessee contended that the amendment was substantive and could not have retrospective operation absent express legislative direction.
Issue. Whether amendments to taxing statutes operate prospectively unless the legislature has expressly or by necessary implication conferred retrospective effect.
HELD. The Constitution Bench reaffirmed the general rule against retrospectivity of taxing statutes. A taxing provision must be construed prospectively unless the language compels otherwise; mere insertion or substitution by amendment is not sufficient to deny vested rights.
“Of the various rules guiding how a legislation has to be interpreted, one established rule is that unless a contrary intention appears, a legislation is presumed not to be intended to have a retrospective operation.”
Relevance. Anchor authority for any argument that an amendment to a charging or computational provision must apply only from the AY notified — useful in transitional disputes around FA 2025 and the 1961 → 2025 changeover.
Facts. Section 52(2) (since deleted) deemed sale consideration to be FMV where FMV exceeded the declared consideration by 15%. The Department applied it on a literal reading even when the assessee had not in fact received more than the declared price.
Issue. Whether a deeming provision in a charging schema can be construed literally where its plain reading produces a result manifestly contrary to legislative object.
HELD. The Court read down section 52(2) to apply only where the assessee had actually received consideration in excess of the declared sum. A literal construction yielding absurd or unjust results must yield to an object-based interpretation; the CBDT's contemporaneous Circular No. 96 was held binding on the Revenue.
“It is well settled that a literal construction of a statutory provision ought not to be adopted if it produces a manifestly unjust result… Where a literal construction creates an anomaly, the courts will adopt that construction which avoids the anomaly.”
Relevance. Anchor authority for purposive construction of deeming fictions across the 1961 Act — applies wherever a deeming clause (e.g., s. 50C, s. 56(2)(x), s. 2(22)(e)) yields a result contrary to legislative purpose.
Facts. Section 14A required disallowance of expenditure incurred to earn exempt income. The dispute was whether the disallowance applies to strategic investments (long-term holdings yielding occasional exempt dividends) and whether Rule 8D's formulaic mechanism applies in all cases.
Issue. Scope of section 14A disallowance — does it apply only where the dominant purpose is earning exempt income, or to all expenditure with some nexus to exempt income, however incidental?
HELD. The Court adopted the 'apportionment' approach: expenditure with a proximate nexus to exempt income is disallowable; strategic-investment argument rejected. Rule 8D applies but only after AO records dissatisfaction with the assessee's claim or working under section 14A(2).
“The principal reason for enactment of section 14A is that certain incomes are not includible while computing total income, as no tax is payable… It would be against the principle if expenses are not allocated against such income from which it is incurred.”
Relevance. Operative framework for section 14A and Rule 8D — relevant for all investment-heavy assessees; partially modulated by FA 2022 amendment deeming disallowance to apply even where no exempt income earned (under ongoing challenge).
▸ Commissioner of Income-tax v. B.C. Srinivasa Setty (1981) 128 ITR 294 ; (1981) 2 SCC 460 (Supreme Court)
Facts. The assessee transferred goodwill of a self-generated nature. The Department sought to tax the consideration as capital gains; the assessee contended that no cost of acquisition could be ascertained, hence the computation provisions failed.
Issue. Whether capital gains arises where the asset has no ascertainable cost of acquisition — i.e., whether the charging provision can be invoked independently of a workable computation provision.
HELD. The charging section and the computation provisions form an integrated code; if the computation provisions cannot apply (because the cost is incapable of ascertainment), the charge itself fails. Self-generated goodwill is not taxable as capital gains.
“The charging section and the computation provisions together constitute an integrated code. When there is a case to which the computation provisions cannot apply at all, it is evident that such a case was not intended to fall within the charging section.”
Relevance. Anchor for the 'charge fails when computation fails' doctrine — useful in valuation impasses, self-generated assets, and computational ambiguity (though now largely overtaken by section 55(2)(a)(i) deeming cost as nil).
▸ Commissioner of Income-tax v. Excel Industries Ltd. (2013) 358 ITR 295 ; (2014) 2 SCC 1 (Supreme Court)
Facts. The assessee, an export-oriented unit, received DEPB licences and Advance Licences. The Department sought to tax the value of these incentives on accrual at the time of issue; the assessee contended that no income accrued until the licence was actually used or sold.
Issue. When does income accrue under the mercantile system — at the moment a right is created, or at the moment the right becomes enforceable as a debt?
HELD. Income accrues only when there is a corresponding liability of the other party. Mere creation of a contingent or unmatured right does not amount to accrual; the right must crystallise into a debt before tax incidence.
“Income accrues when there arises in favour of the assessee a debt — when there is a corresponding liability of the other party to pay the amount. It is not enough that the right has come into being; the right must ripen into a debt.”
Relevance. Anchor for accrual-vs-receipt timing disputes under section 5 / section 145 — relevant for retention monies, export incentives, contingent claim settlements, milestone-based contracts.
CBDT CIRCULARS — ECOSYSTEM
▸ CBDT Circular No. 14(XL-35) of 1955 dated 11 April 1955
Subject. Duty of officers to assist assessees in claiming and securing relief
Substance. Foundational circular directing that the AO should not exploit assessee ignorance to deny legitimate reliefs; officer is required to draw attention to refunds or reliefs to which the assessee is entitled. The circular has been judicially noted in several appellate decisions and remains operative for first-appellate practice.
Substance. Explained the FA 1987 / FA 1989 amendments unifying the previous year with the financial year preceding the AY, including transitional provisions for assessees with different accounting years. Useful in any controversy on the timing of accrual / chargeability for early post-1989 AYs.
▸ CBDT Circular No. 5 of 2014 dated 11 February 2014
Subject. Section 14A — dis-allowance even where no exempt income earned (since modulated)
Substance. Initially directed AOs to apply Rule 8D disallowance under section 14A even where no exempt income was earned in the year; subsequently modulated by Cheminvest (Del HC) and Maxopp (SC). FA 2022 amendment to section 14A re-asserted the position but remains under litigation.
▸ CBDT Circular No. 6 of 2019 dated 20 March 2019
Subject. Withdrawal of low-tax-effect appeals — monetary thresholds
Substance. Revised monetary thresholds for departmental appeals — ITAT (Rs 50L), HC (Rs 1 Cr), SC (Rs 2 Cr); subsequently further revised. Operates as a non-statutory limitation on the Revenue's appellate engagement, binding under section 119.
Substance. Procedural guidance for AOs handling transitional reassessment notices for AYs 2013-14 to 2017-18 affected by Ashish Agarwal and Rajeev Bansal. Sets out the form of section 148A inquiry, time-bar calculation under TOLA, and JAO/FAO jurisdiction in faceless cases.
