Section 48 — Mode of Computation of Capital Gains

STATUTORY ARCHITECTURE — 18-ROW MAP

HISTORICAL CONTEXT

Section 48 is the computational provision for the Capital Gains head — defining the operative formula: Capital Gain = Sale Consideration − (Transfer Expenses + Cost of Acquisition + Cost of Improvement). The cost components are indexed (historically) under the second proviso for LTCG (except NR-share gains under first proviso). The FA 2024 fundamental restructuring — indexation abolition for transfers on or after 23-7-2024 — changes the operative framework significantly.

Cost Inflation Index (CII) — historically annually notified by CBDT — applied to cost of acquisition + improvement to compute indexed cost: Indexed Cost = Original Cost × (CII of transfer year / CII of acquisition year). The base year was 1-4-1981 historically; FA 2017 shifted it to 1-4-2001 (subject to election under s. 55(2)(b)). The FA 2024 retains CII for transfers BEFORE 23-7-2024; abolishes for unlisted post 23-7-2024.

FA 2024 framework for immovable property: For property purchased before 23-7-2024, taxpayer has CHOICE OPTION — (a) Compute LTCG at 12.5% WITHOUT indexation; OR (b) Compute LTCG at 20% WITH indexation. The lower of two is taxable. This grandfathering applies only to immovable property pre-23-7-2024; other unlisted assets — direct 12.5% without indexation.

Section 48 first proviso — special framework for non-residents holding shares / debentures of Indian company: cost / consideration / expenses converted to ORIGINAL FOREIGN CURRENCY at acquisition rates; gain computed in foreign currency; result re-converted to INR. This protects NR investors from rupee-depreciation-inflated gains. FA 2024 preserved this proviso.

Section 50 — depreciable assets (block of assets) — no indexation; entire WDV-residual treated as STCG regardless of holding period. Section 50B slump sale — special computation. Section 50C — stamp duty value override. These specialised provisions take precedence over section 48 general computation.

The transition to the Income-tax Act, 2025 preserves section 48 architecture with all FA 2024 rate / indexation changes intact.

JUDICIAL EVOLUTION — VERIFIED LANDMARK AUTHORITIES

▸ 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. Vatika Township Pvt. Ltd. (2014) 367 ITR 466 ; (2015) 1 SCC 1 (Supreme Court — 5-Judge Constitution Bench)

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.

▸ K.P. Varghese v. Income-tax Officer, Ernakulam (1981) 131 ITR 597 ; (1981) 4 SCC 173 (Supreme Court — 3-Judge Bench)

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.

▸ Mathuram Agrawal v. State of Madhya Pradesh (1999) 8 SCC 667 ; (2000) 1 SCR 1 (Supreme Court)

Facts. A municipal levy was challenged on the ground that the charging provision did not clearly specify the rate, the persons charged, and the measure of tax.

Issue. Whether a tax can be imposed in the absence of a clear, unambiguous charging provision identifying the subject, measure, rate, and incidence.

HELD. Article 265 demands that tax be levied only by clear authority of law. The four components — taxable event, person, rate, and measure — must be clearly discernible from the charging provision; ambiguity is fatal to the levy.

“The intention of the Legislature in a taxation statute is to be gathered from the language of the provisions, particularly when the language is plain and unambiguous. In a taxing Act it is not possible to assume any intention or governing purpose other than what is given expression to.”

Relevance. Foundational authority on the rigour required of charging sections — underpins arguments that ambiguous deeming fictions, surcharge formulas, and rate prescriptions must be strictly construed.

▸ 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.

▸ CBDT Circular No. 549 dated 31 October 1989

Subject. Explanatory notes — Finance Act 1989 amendments (incl. PY unification)

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.
