HISTORICAL CONTEXT
Section 32 is the operative depreciation framework. Architecture: (a) Block of assets — assets of same depreciation rate grouped; WDV (Written Down Value) method standard; straight-line method limited; (b) 180-day rule — assets used < 180 days in PY get 50% rate; (c) Section 32(2) — unabsorbed depreciation indefinite carry-forward (unlike s. 72 business loss 8-year CF).
Depreciation rates — Rule 5 schedule: general 15%; buildings 10%; furniture 10%; computers / software 40%; intangibles 25%; new manufacturing additional 20% (s. 32(1)(iia)). FA 2024 — additional depreciation framework reshuffled. Section 50 — block-of-assets capital gains framework operates parallel.
Practitioner significance — comprehensive computation discipline. Block-of-assets register quarterly + annually. Schedule DPM / DOA in ITR. Section 32(2) unabsorbed depreciation is structurally generous — INDEFINITE CF (distinguish from s. 72 8-year business loss CF). Section 79A — search assessment bar applies to unabsorbed depreciation too (FA 2022).
The transition to the Income-tax Act, 2025 preserves the PGBP framework.
FINANCE ACT AMENDMENT TIMELINE
■ FA 1962 — Section 32 came into force.
■ FA 1989 — Block of assets framework introduced.
■ FA 1992 — 180-day rule.
■ FA 1998 — Intangibles depreciation framework.
■ FA 2002 — Additional depreciation 20% for new manufacturing.
■ FA 2017 — Computer depreciation rate revised to 40%.
■ FA 2022 — Section 79A search loss bar (unabsorbed depreciation).
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.
▸ 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).
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.
▸ 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.
▸ 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.
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.

Caution — corrections in this revision
This revision applies the FA 2026 overlay against the prior v2 (FA 2025) draft. Variant comparison performed: two Cowork files supplied for s. 32 — the un-suffixed original (3,539 words) and the EXPANDED v2 (2026-05-25; 4,555 words). The original’s Block 1 was found INCOMPLETE in respect of the marginal heading and certain footnote attributions; the EXPANDED v2 carries the correct, complete verbatim text for sub-section (1) and following sub-sections. Beyond Block 1, original contributed no substantive unique content; EXPANDED v2 taken as canonical base. Changes recorded: (i) masthead caption updated “as amended by the Finance Act, 2025” → “as amended by the Finance Act, 2026”; (ii) Finance Act Amendment Timeline carries a new closing bullet “Finance Act, 2026 (Act 4 of 2026) — no amendment to s. 32” — s. 32 is not on the FA 2026 Chapter III Part A footprint; (iii) one illustration fact-year anchor re-aligned from PY 2024-25 to PY 2025-26. Open audit FLAGs — SUBSTANTIAL OPEN ISSUES on s. 32 specifically because this is one of the largest and most-litigated sections in the Act: (a) the v2 base’s Block 1 verbatim text is significantly compressed and does NOT include the full text of all sub-sections (s. 32 in the bare Act runs to sub-sections (1) clauses (i)/(ii)/(iia) with multiple provisos and Explanations, (2), Explanation 5 on machinery/plant ownership question, etc.). The v2 file is ~44KB which is below the expected size for a fully-expanded s. 32 file with the complete bare-Act Block 1 text; full Block 1 audit pending against the bare-Act PDF — this section may warrant A/B/C/D batch split at master pass per the user’s standing protocol for long sections; (b) the additional-depreciation regime under s. 32(1)(iia) (FA 2002 inserted, FA 2012 enhanced, FA 2015 carve-outs for backward-area undertakings) requires verification against the bare-Act footnote series; (c) Block 2 right-hand column cites “Section 32 successor” without naming the Income-tax Act, 2025 (Act 30 of 2025) successor section number — pending verified successor mapping; (d) the case-law list is the generic Cowork template — the leading depreciation authorities (Mysore Minerals Ltd v. CIT (1999) 239 ITR 775 (SC) on beneficial-ownership for depreciation; ICDS Ltd v. CIT (2013) 350 ITR 527 (SC) on registered-ownership-not-essential for leasing companies; Goetze (India) Ltd v. CIT (2006) 284 ITR 323 (SC) on additional-depreciation claim through revised return; CIT v. Madras Cements Ltd (2008) 311 ITR 86 (Mad HC); CIT v. Aravali Constructions (2001) 121 Taxman 145 (Raj HC) on user-test for depreciation; CIT v. Vayithri Plantations Ltd (1981) 128 ITR 675 (SC) on passive user) are absent — this is a particularly significant gap given the s. 32 jurisprudence is exceptionally well-developed; (e) the depreciation rates and block-of-assets framework warrant a verified-cross-reference to Rule 5 of the Income-tax Rules, 1962 and Appendix I (depreciation schedule); not currently in the file; (f) the Cowork v3 base does not carry a separate Source & verification notes cell (Standard B v2 requirement) — logged for forward-pass. NOTE TO USER: this section will require a substantive Block 1 + commentary expansion at master pass to meet the practitioner-edition depth standard set out in the project charter (alongside Sampath Iyengar / Chaturvedi & Pithisaria / Kanga & Palkhivala).
Case Laws & Commentary
SECTION 32 — Depreciation
Important Case Laws — 1961 Treatise (FA 2026)
Provision in brief: Provides for depreciation on tangible assets (buildings, machinery, plant, furniture) and intangible assets (know-how, patents, copyrights, trademarks, licences, franchises, business/commercial rights — but not goodwill, since FA 2021), owned wholly or partly and used for business/profession, at WDV / block-of-assets rates prescribed. Includes additional depreciation u/s 32(1)(iia), 50% rule for assets used <180 days, depreciation in case of succession (Expln 7A), unabsorbed depreciation carry-forward u/s 32(2). Goodwill expressly excluded by FA 2021 (Expln 3 amended; new clause in s. 50).
Section Commentary
Centrepiece of the deductions scheme
Section 32 governs depreciation, the single most-significant deduction in computing PGBP for capital-intensive businesses. It applies to (a) tangible assets — buildings, machinery, plant, furniture, and (b) intangible assets — know-how, patents, copyrights, trademarks, licences, franchises, business / commercial rights of similar nature (but excluding goodwill since FA 2021). Section 32 must be read with s. 43 (definitions including 'actual cost', 'WDV', 'block of assets'), s. 43A (FX adjustment) and s. 50 (capital gains on depreciable assets).
Twin conditions — ownership and user
Two conditions must be cumulatively satisfied: (i) the assessee must OWN the asset (wholly or partly), and (ii) the asset must be USED for the purposes of business or profession. Mysore Minerals expanded 'owner' to include beneficial owners — registered title is not indispensable. ICDS Ltd. (2013) (SC) settled that in finance-lease / operating-lease arrangements, the lessor (not lessee) is the owner for s. 32 purposes; this overturned the 'user theory' previously advanced by some tribunals. 'Used' includes 'ready for use' / 'kept ready' — the asset need not be physically in use throughout the year, only during the year.
Block of assets concept
Since AY 1988-89, depreciation is computed on a block-of-assets basis (s. 2(11), s. 43(6)). All assets within a class and rate of depreciation form one block; additions and deductions are aggregated; depreciation is computed on the WDV of the block. Individual-asset depreciation went away. The block survives as long as it has positive WDV; if WDV becomes negative or zero, s. 50 short-term capital gain/loss is triggered. For new acquisitions used <180 days, the 50% rule (second proviso to s. 32(1)) restricts depreciation to half the rate, but the asset still enters the block at full cost.
An incentive of additional 20% (35% for backward areas under sub-s. (1)(iia)(B)) on NEW plant and machinery (excluding office equipment, vehicles, ships, aircraft, plant installed in office/residence) acquired and installed by manufacturer or producer. Where the asset is acquired and used <180 days, half (10%) is allowed in the year of acquisition and the balance (10%) in the immediately succeeding year — a planning point introduced by FA 2015 to redress the long-standing grievance that the 50% rule permanently denied the lost half. Additional depreciation is over-and-above normal depreciation.
Mandatory nature post-FA 2001
Mahendra Mills (SC 2000) had allowed assessee the option to skip depreciation to maximise business-loss carry-forward (which has 8-year life vs unabsorbed depreciation's perpetual life). FA 2001 inserted Expln 5 to s. 32(1) making depreciation MANDATORY whether or not the assessee claims it in the return. Plastiblends India (SC 2017) confirmed that this applies in computing Chapter VIA (s. 80-IA / IB) eligible profits as well. The pre-2002 planning trick is therefore dead.
Goodwill — FA 2021 carve-out
Smifs Securities (SC 2012) had treated goodwill as a depreciable intangible. FA 2021 reversed this prospectively from AY 2021-22: goodwill of any nature (including arising on amalgamation or otherwise) is NO LONGER part of any block of assets and no depreciation is allowable. Consequentially, s. 50 was amended to deal with the WDV-reduction for transition. For pending pre-2021 assessments, Smifs Securities still controls.
Where current year depreciation cannot be set off in full (insufficient profits), the unabsorbed depreciation is carried forward — and merges with current year depreciation of the succeeding year (no time limit, no continuity-of-business requirement — different from s. 72 business loss). Set-off priority: current year depreciation → brought forward business losses → unabsorbed depreciation. Carry-forward survives change in shareholding (unlike s. 79) and is available against any head of income.
CA's compliance and planning matrix
(i) Maintain block-wise depreciation register reconciling opening WDV → additions → deletions → depreciation → closing WDV. (ii) For 180-day rule, track date of 'put to use' (not date of acquisition / installation alone). (iii) For additional depreciation, ensure 'manufacturer/producer' status and 'new asset' status (Form 3CD Cl. 18 disclosure). (iv) For goodwill in M&A post-FA 2021, evaluate the s. 50 transition impact. (v) For unabsorbed depreciation carry-forward, ensure timely return-filing (though not a precondition, missed returns expose to re-assessment).
FA 2026 impact: No further amendment to s. 32 in FA 2026 (key earlier amendments: FA 2021 anti-goodwill block; FA 2025 — no change). Additional depreciation rule u/s 32(1)(iia) unchanged.
Leading Decisions
1. CIT v. Smifs Securities Ltd.
Citation: (2012) 348 ITR 302 (SC)
Forum: Supreme Court of India
Facts & Issue: On amalgamation, the assessee paid consideration in excess of the net assets acquired and recorded the excess as 'goodwill' in its books. It claimed depreciation u/s 32 on the goodwill as an 'asset of the like nature' to those listed (know-how, patents, etc.) in s. 32(1)(ii).
Held / Ratio: The Supreme Court held that goodwill arising on amalgamation is an 'asset' within the meaning of Explanation 3(b) to s. 32(1) and depreciation is allowable. The principle of ejusdem generis with 'business or commercial rights of similar nature' was applied — goodwill confers commercial right and value. This decision was effectively reversed prospectively by FA 2021, which excluded goodwill from the depreciable block and provided for capital-gains computation on transfer.
Section relevance: Was the controlling authority on depreciation of goodwill until FA 2021. Continues to govern AYs up to 2020-21; from AY 2021-22 onward, goodwill is non-depreciable.
2. CIT v. Mahendra Mills
Citation: (2000) 243 ITR 56 (SC)
Forum: Supreme Court of India
Facts & Issue: Assessee chose not to claim depreciation u/s 32 in a year so as to maximise carry-forward of business losses (which have a longer carry-forward life than unabsorbed depreciation). Revenue insisted depreciation must be granted compulsorily.
Held / Ratio: The Supreme Court held that depreciation is an allowance and the assessee can opt out of claiming it. Depreciation is not a charge automatically fastened on income. This was the position till AY 2001-02. Thereafter, by FA 2001, Expln 5 to s. 32(1) was inserted making depreciation MANDATORY whether or not claimed.
Section relevance: Historic foundation — superseded prospectively by FA 2001 (Expln 5). Important for understanding the pre-2002 regime and continuing for pre-AY 2002-03 disputes.
Facts & Issue: Assessee, a leasing company, leased out trucks/vehicles/cylinders to lessees, who used them. Question: was the leasing company the 'owner' using the assets 'for the purposes of business' so as to qualify for depreciation u/s 32?
Held / Ratio: In ICDS, the Supreme Court held that ownership of the asset and use 'for purposes of business' are satisfied by the lessor in a financial-lease/operating-lease arrangement — the asset is the stock of the lessor's leasing business and the income from leasing is its profit. Depreciation is allowable. The Court rejected the 'user theory' that requires physical use by the assessee.
Section relevance: Defines 'ownership' and 'use for business' under s. 32 in leasing transactions — controlling authority.
4. Mysore Minerals Ltd. v. CIT
Citation: (1999) 239 ITR 775 (SC)
Forum: Supreme Court of India
Facts & Issue: Assessee acquired buildings under HBA scheme but legal title (registration) was incomplete at the close of the year. It used the buildings for business and claimed depreciation. Revenue denied on want of registered title.
Held / Ratio: The Supreme Court held that 'owned by the assessee' in s. 32(1) does not require registered legal title in every case. Beneficial ownership coupled with dominion, possession and use suffices. The Court emphasised that the section deals with depreciation, an income-tax allowance, not a property law concept.
Section relevance: Cardinal authority on the meaning of 'owner' under s. 32 — beneficial-ownership theory.
5. CIT v. Dinjoye Tea Estate (P) Ltd.
Citation: (1997) 224 ITR 263 (Gau)
Forum: Gauhati High Court (principle approved at SC level in subsequent cases)
Facts & Issue: Disputed claim of depreciation where asset was used for part of the year, less than 180 days, and the assessee claimed full year's rate.
Held / Ratio: Held that the second proviso to s. 32(1) restricts depreciation to 50% of the prescribed rate where the asset is acquired and put to use in the PY for less than 180 days. The rule is mandatory, not directory.
Section relevance: Standard authority on operation of the 180-day rule under second proviso to s. 32(1).
6. CIT v. Madras Industrial Investment Corpn. Ltd. (interest-on-deposits cost)
Citation: (1997) 225 ITR 802 (SC)
Forum: Supreme Court of India
Facts & Issue: Cited under depreciation analyses for the proposition that 'actual cost' computation includes spread-over of pre-production interest and discounts.
Held / Ratio: As discussed under s. 29, the Court allowed spread of debenture discount. The principle informs computation of 'actual cost' u/s 43(1) feeding into the block of assets for s. 32.
Section relevance: Establishes the link between commercial accountancy and statutory 'actual cost' under s. 43(1) — affects depreciation base under s. 32.
7. Plastiblends India Ltd. v. Addl. CIT
Citation: (2017) 398 ITR 568 (SC)
Forum: Supreme Court of India
Facts & Issue: Assessee, eligible for deduction u/s 80-IA, claimed less depreciation u/s 32 to inflate Chapter VIA profits. Question: whether depreciation u/s 32 is mandatory while computing 'profits' for s. 80-IA.
Held / Ratio: The Supreme Court held that depreciation u/s 32 is mandatory in view of Expln 5 inserted by FA 2001. Profits eligible for s. 80-IA / 80-IB must be computed after deducting depreciation, even if the assessee chooses not to claim. This affirms the legislative reversal of Mahendra Mills.
Section relevance: Restates the mandatory nature of depreciation under s. 32(1) post-FA 2001 and links it to Chapter VIA computations.

HISTORICAL CONTEXT
Section 32 is the operative depreciation framework. Architecture: (a) Block of assets — assets of same depreciation rate grouped; WDV (Written Down Value) method standard; straight-line method limited; (b) 180-day rule — assets used < 180 days in PY get 50% rate; (c) Section 32(2) — unabsorbed depreciation indefinite carry-forward (unlike s. 72 business loss 8-year CF).
Depreciation rates — Rule 5 schedule: general 15%; buildings 10%; furniture 10%; computers / software 40%; intangibles 25%; new manufacturing additional 20% (s. 32(1)(iia)). FA 2024 — additional depreciation framework reshuffled. Section 50 — block-of-assets capital gains framework operates parallel.
Practitioner significance — comprehensive computation discipline. Block-of-assets register quarterly + annually. Schedule DPM / DOA in ITR. Section 32(2) unabsorbed depreciation is structurally generous — INDEFINITE CF (distinguish from s. 72 8-year business loss CF). Section 79A — search assessment bar applies to unabsorbed depreciation too (FA 2022).
The transition to the Income-tax Act, 2025 preserves the PGBP framework.

JUDICIAL EVOLUTION — VERIFIED LANDMARK AUTHORITIES
▸ 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.
▸ 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).
▸ 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.
▸ 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.
▸ 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.
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.
▸ CBDT Circular No. 5 of 2024 dated 15 March 2024
Subject. Procedure for transitional reassessment notices post-Ashish Agarwal / Rajeev Bansal
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.
WORKED EXAMPLES
Illustration — Illustration 1 — Standard block depreciation
Facts. A's plant + machinery block: Opening WDV Rs 50 L; New addition Rs 20 L (used 200 days).
Computation.
Block addition > 180 days → full rate.
Total WDV before depreciation = Rs 70 L.
Depreciation 15% × Rs 70 L = Rs 10.5 L.
Closing WDV = Rs 70 L − Rs 10.5 L = Rs 59.5 L.
Result. Standard block depreciation; > 180 days full rate.
Illustration — Illustration 2 — 180-day rule
Facts. B's machinery purchased 1-November-2024; used 150 days only.
Computation.
S. 32 second proviso — Used < 180 days → 50% rate.
Normal rate 15% × 50% = 7.5% applicable.
Half-year depreciation framework.
Result. 180-day rule operative; preserve usage-date evidence.
Illustration — Illustration 3 — Unabsorbed depreciation CF
Facts. C has Rs 30 L depreciation; PGBP profit only Rs 10 L; Rs 20 L unabsorbed.
Computation.
S. 32(2) — Indefinite CF.
PY 2025-26: Use Rs 10 L; balance Rs 20 L → CF.
Future PY: Rs 20 L absorbed against future PGBP / other heads (except salary).
Distinct from s. 72 business loss 8-year CF.
Result. Section 32(2) unabsorbed depreciation — indefinite CF + cross-head absorption.
Illustration — Illustration 4 — Additional depreciation
Facts. D's new manufacturing plant Rs 1 cr; eligible for s. 32(1)(iia) additional depreciation.
Computation.
S. 32(1)(iia) — Additional 20% for new manufacturing.
Standard 15% + Additional 20% = 35% in year of acquisition.
If used < 180 days → 17.5% in year + balance 17.5% next year.
Significant first-year tax shield.
Result. Section 32(1)(iia) additional depreciation incentive.
Illustration — Illustration 5 — Intangibles
Facts. E acquires patent Rs 50 L.
Computation.
S. 32(1)(ii) — Intangibles framework.
Rule 5 — Intangibles 25% depreciation.
PY 1 (200 days use) Rs 50 L × 25% = Rs 12.5 L.
Subsequent years on WDV.
Result. Intangibles depreciation post-1998 framework; 25% rate.

Caution — corrections in this revision
This revision applies the FA 2026 overlay against the prior v2 (FA 2025) draft. Variant comparison performed: two Cowork files supplied for s. 32 — the un-suffixed original (3,539 words) and the EXPANDED v2 (2026-05-25; 4,555 words). The original’s Block 1 was found INCOMPLETE in respect of the marginal heading and certain footnote attributions; the EXPANDED v2 carries the correct, complete verbatim text for sub-section (1) and following sub-sections. Beyond Block 1, original contributed no substantive unique content; EXPANDED v2 taken as canonical base. Changes recorded: (i) masthead caption updated “as amended by the Finance Act, 2025” → “as amended by the Finance Act, 2026”; (ii) Finance Act Amendment Timeline carries a new closing bullet “Finance Act, 2026 (Act 4 of 2026) — no amendment to s. 32” — s. 32 is not on the FA 2026 Chapter III Part A footprint; (iii) one illustration fact-year anchor re-aligned from PY 2024-25 to PY 2025-26. Open audit FLAGs — SUBSTANTIAL OPEN ISSUES on s. 32 specifically because this is one of the largest and most-litigated sections in the Act: (a) the v2 base’s Block 1 verbatim text is significantly compressed and does NOT include the full text of all sub-sections (s. 32 in the bare Act runs to sub-sections (1) clauses (i)/(ii)/(iia) with multiple provisos and Explanations, (2), Explanation 5 on machinery/plant ownership question, etc.). The v2 file is ~44KB which is below the expected size for a fully-expanded s. 32 file with the complete bare-Act Block 1 text; full Block 1 audit pending against the bare-Act PDF — this section may warrant A/B/C/D batch split at master pass per the user’s standing protocol for long sections; (b) the additional-depreciation regime under s. 32(1)(iia) (FA 2002 inserted, FA 2012 enhanced, FA 2015 carve-outs for backward-area undertakings) requires verification against the bare-Act footnote series; (c) Block 2 right-hand column cites “Section 32 successor” without naming the Income-tax Act, 2025 (Act 30 of 2025) successor section number — pending verified successor mapping; (d) the case-law list is the generic Cowork template — the leading depreciation authorities (Mysore Minerals Ltd v. CIT (1999) 239 ITR 775 (SC) on beneficial-ownership for depreciation; ICDS Ltd v. CIT (2013) 350 ITR 527 (SC) on registered-ownership-not-essential for leasing companies; Goetze (India) Ltd v. CIT (2006) 284 ITR 323 (SC) on additional-depreciation claim through revised return; CIT v. Madras Cements Ltd (2008) 311 ITR 86 (Mad HC); CIT v. Aravali Constructions (2001) 121 Taxman 145 (Raj HC) on user-test for depreciation; CIT v. Vayithri Plantations Ltd (1981) 128 ITR 675 (SC) on passive user) are absent — this is a particularly significant gap given the s. 32 jurisprudence is exceptionally well-developed; (e) the depreciation rates and block-of-assets framework warrant a verified-cross-reference to Rule 5 of the Income-tax Rules, 1962 and Appendix I (depreciation schedule); not currently in the file; (f) the Cowork v3 base does not carry a separate Source & verification notes cell (Standard B v2 requirement) — logged for forward-pass. NOTE TO USER: this section will require a substantive Block 1 + commentary expansion at master pass to meet the practitioner-edition depth standard set out in the project charter (alongside Sampath Iyengar / Chaturvedi & Pithisaria / Kanga & Palkhivala).
Case Laws & Commentary
SECTION 32 — Depreciation
Important Case Laws — 1961 Treatise (FA 2026)
Provision in brief: Provides for depreciation on tangible assets (buildings, machinery, plant, furniture) and intangible assets (know-how, patents, copyrights, trademarks, licences, franchises, business/commercial rights — but not goodwill, since FA 2021), owned wholly or partly and used for business/profession, at WDV / block-of-assets rates prescribed. Includes additional depreciation u/s 32(1)(iia), 50% rule for assets used <180 days, depreciation in case of succession (Expln 7A), unabsorbed depreciation carry-forward u/s 32(2). Goodwill expressly excluded by FA 2021 (Expln 3 amended; new clause in s. 50).
Section Commentary
Centrepiece of the deductions scheme
Section 32 governs depreciation, the single most-significant deduction in computing PGBP for capital-intensive businesses. It applies to (a) tangible assets — buildings, machinery, plant, furniture, and (b) intangible assets — know-how, patents, copyrights, trademarks, licences, franchises, business / commercial rights of similar nature (but excluding goodwill since FA 2021). Section 32 must be read with s. 43 (definitions including 'actual cost', 'WDV', 'block of assets'), s. 43A (FX adjustment) and s. 50 (capital gains on depreciable assets).
Twin conditions — ownership and user
Two conditions must be cumulatively satisfied: (i) the assessee must OWN the asset (wholly or partly), and (ii) the asset must be USED for the purposes of business or profession. Mysore Minerals expanded 'owner' to include beneficial owners — registered title is not indispensable. ICDS Ltd. (2013) (SC) settled that in finance-lease / operating-lease arrangements, the lessor (not lessee) is the owner for s. 32 purposes; this overturned the 'user theory' previously advanced by some tribunals. 'Used' includes 'ready for use' / 'kept ready' — the asset need not be physically in use throughout the year, only during the year.
Block of assets concept
Since AY 1988-89, depreciation is computed on a block-of-assets basis (s. 2(11), s. 43(6)). All assets within a class and rate of depreciation form one block; additions and deductions are aggregated; depreciation is computed on the WDV of the block. Individual-asset depreciation went away. The block survives as long as it has positive WDV; if WDV becomes negative or zero, s. 50 short-term capital gain/loss is triggered. For new acquisitions used <180 days, the 50% rule (second proviso to s. 32(1)) restricts depreciation to half the rate, but the asset still enters the block at full cost.
Additional depreciation — s. 32(1)(iia)
An incentive of additional 20% (35% for backward areas under sub-s. (1)(iia)(B)) on NEW plant and machinery (excluding office equipment, vehicles, ships, aircraft, plant installed in office/residence) acquired and installed by manufacturer or producer. Where the asset is acquired and used <180 days, half (10%) is allowed in the year of acquisition and the balance (10%) in the immediately succeeding year — a planning point introduced by FA 2015 to redress the long-standing grievance that the 50% rule permanently denied the lost half. Additional depreciation is over-and-above normal depreciation.
Mandatory nature post-FA 2001
Mahendra Mills (SC 2000) had allowed assessee the option to skip depreciation to maximise business-loss carry-forward (which has 8-year life vs unabsorbed depreciation's perpetual life). FA 2001 inserted Expln 5 to s. 32(1) making depreciation MANDATORY whether or not the assessee claims it in the return. Plastiblends India (SC 2017) confirmed that this applies in computing Chapter VIA (s. 80-IA / IB) eligible profits as well. The pre-2002 planning trick is therefore dead.
Goodwill — FA 2021 carve-out
Smifs Securities (SC 2012) had treated goodwill as a depreciable intangible. FA 2021 reversed this prospectively from AY 2021-22: goodwill of any nature (including arising on amalgamation or otherwise) is NO LONGER part of any block of assets and no depreciation is allowable. Consequentially, s. 50 was amended to deal with the WDV-reduction for transition. For pending pre-2021 assessments, Smifs Securities still controls.
Unabsorbed depreciation — s. 32(2)
Where current year depreciation cannot be set off in full (insufficient profits), the unabsorbed depreciation is carried forward — and merges with current year depreciation of the succeeding year (no time limit, no continuity-of-business requirement — different from s. 72 business loss). Set-off priority: current year depreciation → brought forward business losses → unabsorbed depreciation. Carry-forward survives change in shareholding (unlike s. 79) and is available against any head of income.
CA's compliance and planning matrix
(i) Maintain block-wise depreciation register reconciling opening WDV → additions → deletions → depreciation → closing WDV. (ii) For 180-day rule, track date of 'put to use' (not date of acquisition / installation alone). (iii) For additional depreciation, ensure 'manufacturer/producer' status and 'new asset' status (Form 3CD Cl. 18 disclosure). (iv) For goodwill in M&A post-FA 2021, evaluate the s. 50 transition impact. (v) For unabsorbed depreciation carry-forward, ensure timely return-filing (though not a precondition, missed returns expose to re-assessment).
FA 2026 impact: No further amendment to s. 32 in FA 2026 (key earlier amendments: FA 2021 anti-goodwill block; FA 2025 — no change). Additional depreciation rule u/s 32(1)(iia) unchanged.
Leading Decisions
1. CIT v. Smifs Securities Ltd.
Citation: (2012) 348 ITR 302 (SC)
Forum: Supreme Court of India
Facts & Issue: On amalgamation, the assessee paid consideration in excess of the net assets acquired and recorded the excess as 'goodwill' in its books. It claimed depreciation u/s 32 on the goodwill as an 'asset of the like nature' to those listed (know-how, patents, etc.) in s. 32(1)(ii).
Held / Ratio: The Supreme Court held that goodwill arising on amalgamation is an 'asset' within the meaning of Explanation 3(b) to s. 32(1) and depreciation is allowable. The principle of ejusdem generis with 'business or commercial rights of similar nature' was applied — goodwill confers commercial right and value. This decision was effectively reversed prospectively by FA 2021, which excluded goodwill from the depreciable block and provided for capital-gains computation on transfer.
Section relevance: Was the controlling authority on depreciation of goodwill until FA 2021. Continues to govern AYs up to 2020-21; from AY 2021-22 onward, goodwill is non-depreciable.
2. CIT v. Mahendra Mills
Citation: (2000) 243 ITR 56 (SC)
Forum: Supreme Court of India
Facts & Issue: Assessee chose not to claim depreciation u/s 32 in a year so as to maximise carry-forward of business losses (which have a longer carry-forward life than unabsorbed depreciation). Revenue insisted depreciation must be granted compulsorily.
Held / Ratio: The Supreme Court held that depreciation is an allowance and the assessee can opt out of claiming it. Depreciation is not a charge automatically fastened on income. This was the position till AY 2001-02. Thereafter, by FA 2001, Expln 5 to s. 32(1) was inserted making depreciation MANDATORY whether or not claimed.
Section relevance: Historic foundation — superseded prospectively by FA 2001 (Expln 5). Important for understanding the pre-2002 regime and continuing for pre-AY 2002-03 disputes.
3. CIT v. Mirza Ataullaha Baig
Citation: (2008) 304 ITR 1 (SC) / I.C.D.S. Ltd. v. CIT (2013) 350 ITR 527 (SC)
Forum: Supreme Court of India
Facts & Issue: Assessee, a leasing company, leased out trucks/vehicles/cylinders to lessees, who used them. Question: was the leasing company the 'owner' using the assets 'for the purposes of business' so as to qualify for depreciation u/s 32?
Held / Ratio: In ICDS, the Supreme Court held that ownership of the asset and use 'for purposes of business' are satisfied by the lessor in a financial-lease/operating-lease arrangement — the asset is the stock of the lessor's leasing business and the income from leasing is its profit. Depreciation is allowable. The Court rejected the 'user theory' that requires physical use by the assessee.
Section relevance: Defines 'ownership' and 'use for business' under s. 32 in leasing transactions — controlling authority.
4. Mysore Minerals Ltd. v. CIT
Citation: (1999) 239 ITR 775 (SC)
Forum: Supreme Court of India
Facts & Issue: Assessee acquired buildings under HBA scheme but legal title (registration) was incomplete at the close of the year. It used the buildings for business and claimed depreciation. Revenue denied on want of registered title.
Held / Ratio: The Supreme Court held that 'owned by the assessee' in s. 32(1) does not require registered legal title in every case. Beneficial ownership coupled with dominion, possession and use suffices. The Court emphasised that the section deals with depreciation, an income-tax allowance, not a property law concept.
Section relevance: Cardinal authority on the meaning of 'owner' under s. 32 — beneficial-ownership theory.
5. CIT v. Dinjoye Tea Estate (P) Ltd.
Citation: (1997) 224 ITR 263 (Gau)
Forum: Gauhati High Court (principle approved at SC level in subsequent cases)
Facts & Issue: Disputed claim of depreciation where asset was used for part of the year, less than 180 days, and the assessee claimed full year's rate.
Held / Ratio: Held that the second proviso to s. 32(1) restricts depreciation to 50% of the prescribed rate where the asset is acquired and put to use in the PY for less than 180 days. The rule is mandatory, not directory.
Section relevance: Standard authority on operation of the 180-day rule under second proviso to s. 32(1).
6. CIT v. Madras Industrial Investment Corpn. Ltd. (interest-on-deposits cost)
Citation: (1997) 225 ITR 802 (SC)
Forum: Supreme Court of India
Facts & Issue: Cited under depreciation analyses for the proposition that 'actual cost' computation includes spread-over of pre-production interest and discounts.
Held / Ratio: As discussed under s. 29, the Court allowed spread of debenture discount. The principle informs computation of 'actual cost' u/s 43(1) feeding into the block of assets for s. 32.
Section relevance: Establishes the link between commercial accountancy and statutory 'actual cost' under s. 43(1) — affects depreciation base under s. 32.
7. Plastiblends India Ltd. v. Addl. CIT
Citation: (2017) 398 ITR 568 (SC)
Forum: Supreme Court of India
Facts & Issue: Assessee, eligible for deduction u/s 80-IA, claimed less depreciation u/s 32 to inflate Chapter VIA profits. Question: whether depreciation u/s 32 is mandatory while computing 'profits' for s. 80-IA.
Held / Ratio: The Supreme Court held that depreciation u/s 32 is mandatory in view of Expln 5 inserted by FA 2001. Profits eligible for s. 80-IA / 80-IB must be computed after deducting depreciation, even if the assessee chooses not to claim. This affirms the legislative reversal of Mahendra Mills.
Section relevance: Restates the mandatory nature of depreciation under s. 32(1) post-FA 2001 and links it to Chapter VIA computations.
— End of Section 32 Case-Law Note —
