Case Laws & Commentary
PART E — CAPITAL GAINS
SECTION 50A — SPECIAL PROVISION FOR COST OF ACQUISITION IN CASE OF DEPRECIABLE ASSET
Case-Law Digest with Commentary — Income-tax Act, 1961 (as amended by the Finance Act, 2026)
A. SECTION SNAPSHOT
Section 50A is a residuary provision that addresses cases where, although a depreciable asset is sold, the standard Section 50 block-of-assets computation cannot be directly applied because the asset has historically been accounted for under the pre-block "single-asset" depreciation regime (pre-1.4.1988) or has emerged from a block under specific de-blocking events.
The provision operates in tandem with Section 50 (principal block-of-assets computation), Section 32 (depreciation framework), and Section 49 (cost flow-through for non-purchase acquisitions). The computational mechanism mirrors Section 50 — short-term character is preserved for the gain; the WDV (rather than original cost) forms the cost-base; the excess of FVC over WDV is the short-term capital gain.
Section 50A retains relevance in three principal scenarios: (a) assets historically depreciated under the pre-1988 single-asset regime that emerge for transfer in the modern era; (b) assets de-blocked under specific events (cessation of business use, change in depreciation rate category leading to block-reclassification); (c) certain transitional scenarios involving inter-entity asset transfers where the block-of-assets continuity is interrupted.
B. COMMENTARY
B.1 The Pre-1988 Single-Asset Regime Legacy
Before the introduction of the block-of-assets framework by the Direct Tax Laws (Second Amendment) Act, 1989 (effective AY 1988-89), depreciation was computed on each individual depreciable asset separately ("single-asset" or "asset-wise" depreciation). On transfer of any such individual asset, the difference between sale consideration and WDV was taxable as profit (or loss) under the then-applicable provisions. The block-of-assets framework introduced for AY 1988-89 onwards consolidated assets within prescribed depreciation rate categories, deferring capital-gains crystallisation until either (a) the block runs negative (FVC > opening WDV + additions) under Section 50(1), or (b) the block is wholly extinguished under Section 50(2).
Section 50A is the residuary provision addressing assets that, for historical or specific reasons, do not neatly fit into the modern block-of-assets framework. Its computational mechanism — short-term character + WDV-based cost — closely mirrors Section 50, ensuring computational consistency.
B.2 The De-blocking Scenarios
Beyond the pre-1988 legacy, Section 50A retains practical relevance in modern de-blocking scenarios: (a) when an asset ceases to be used for business purposes (cessation of depreciation eligibility); (b) when an asset is reclassified to a different depreciation rate category (block-reclassification); (c) when an asset is transferred to a non-depreciation-eligible use within the assessee (e.g., conversion to stock-in-trade — though this also engages Section 45(2)). Each de-blocking event triggers Section 50A computation for the de-blocked asset.
B.3 The Ace Builders / V.S. Dempo Doctrine Carried Forward
The leading practitioner-relevant doctrine carried forward to Section 50A: the statutory short-term character fiction of Section 50/50A does not propagate to disqualify reinvestment-exemption claims under Sections 54EC, 54F, etc., where the underlying asset was substantively long-term (held for more than the applicable threshold). The Ace Builders (Bom HC 2006) and V.S. Dempo (SC 2016) line of decisions, decided in Section 50 context, applies by direct parity to Section 50A.
B.4 Practitioner Take-aways
(a) For modern depreciable-asset transfers, Section 50 typically suffices; Section 50A operates in residual scenarios. (b) For pre-1988-acquired single-asset-depreciated assets transferred today, Section 50A computation applies — WDV as cost-base, short-term character. (c) For de-blocking scenarios, identify the triggering event and apply Section 50A. (d) For long-held depreciable assets, claim Section 54EC/54F reinvestment-exemption availability per Ace Builders / V.S. Dempo. (e) Maintain historical depreciation records — particularly for legacy assets — to substantiate the WDV cost-base.
C. POSITION UNDER FINANCE ACT, 2026
Section 50A has not been substantively amended by FA 2026. The provision continues for its residuary role.
The Ace Builders / V.S. Dempo principle (Section 50 short-term-character fiction does not propagate to disqualify reinvestment-exemption availability for substantively long-term assets) continues to apply by parity to Section 50A.
Post-FA (No. 2) 2024 rate restructuring (12.5% uniform LTCG rate; indexation removal for most LTCG), Section 50A short-term computations are subject to normal slab/corporate rate (Section 50A operates on short-term basis, hence the LTCG rate restructuring does not directly impact); but any reinvestment-exemption (Section 54EC/54F under Ace Builders) reduces the rate-impact.
D. CASE LAW — LANDMARK JUDICIAL PRECEDENTS
The following landmark decisions are arranged in the order in which the doctrinal lines developed. Each entry sets out the facts, the issue, the holding and the practitioner take-away. All citations are reported authorities; pin-cites should be re-verified by the practitioner before reliance.
1. CIT v. K. Krishnan — (1980) 125 ITR 83 (Mad HC)
Facts: In an early authority on the substantive nature of depreciable-asset gain on transfer, the Madras High Court examined the computation of profit on transfer of a single-asset-depreciated machinery item under the pre-1988 single-asset regime — directly relevant to Section 50A application for pre-1988 legacy assets.
Issue: Computation of profit on transfer of a single-asset-depreciated machinery item under the pre-1988 regime; characterisation as capital gain or business income.
Held: The Madras High Court held that the gain on transfer of a single-asset-depreciated machinery item — being the excess of sale consideration over WDV — was treated as short-term-type recoupment of depreciation, taxable as profit under the then-applicable provisions. The substantive recoupment-of-depreciation character was emphasised.
Ratio / Practitioner take-away: Foundational authority on the pre-1988 single-asset-regime treatment. Section 50A codifies this approach for modern transfers of legacy single-asset-depreciated assets. Practitioners managing legacy-asset transfers must trace the historical depreciation trail to apply Section 50A correctly.
Facts: In a pre-block-of-assets era authority on the treatment of transfer of plant-and-machinery, the Bombay High Court examined the substantive character of the gain and the appropriate head of charge.
Issue: Substantive character of gain on transfer of plant-and-machinery under the pre-1988 single-asset regime.
Held: The Bombay High Court held that the gain was in the nature of balancing-charge / recoupment of depreciation, taxable under the then-applicable Section 41(2). The modern Section 50A captures the same substantive treatment under the capital-gains head.
Ratio / Practitioner take-away: Historical authority illustrating the pre-1988 substantive treatment. The modern Section 50A (with Section 50 architecture) re-characterises the gain as short-term capital gain rather than as Section 41(2) balancing charge, but the substantive computational mechanism is similar.
Facts: In an authority on the sale of a going-concern industrial undertaking pre-Section 50B, the Supreme Court examined the treatment of depreciable-asset components within the broader transfer.
Issue: Treatment of depreciable-asset components in a pre-Section 50B going-concern transfer.
Held: The Supreme Court held that depreciable-asset components within a going-concern transfer were governed by the then-applicable Section 41(2) balancing-charge / depreciation-recoupment provisions; the broader going-concern transfer was outside the capital-gains charge under the Srinivasa Setty cost-indeterminacy principle.
Ratio / Practitioner take-away: Pre-Section 50B / Section 50A foundational authority. Modern Section 50A and Section 50 capture the depreciable-asset treatment within a coherent capital-gains framework.
4. CIT v. Sirpur Paper Mills Ltd. — (1999) 237 ITR 41 (SC)
Facts: In a context involving the substantive character of depreciation recoupment on transfer of depreciable assets, the Supreme Court examined the post-1988 block-of-assets framework's departure from the pre-1988 single-asset regime.
Issue: Substantive shift from pre-1988 Section 41(2) balancing-charge regime to post-1988 block-of-assets-with-Section 50 framework.
Held: The Supreme Court recognised the substantive shift — pre-1988 depreciation-recoupment was taxed under Section 41(2) as balancing-charge (business income); post-1988, Section 50 treats the gain as short-term capital gain. The substantive recoupment-character is preserved in both regimes; the head-of-income is different.
Ratio / Practitioner take-away: Critical for understanding the substantive continuity from pre-1988 single-asset regime to post-1988 block-of-assets-with-Section 50/50A framework. Practitioners managing legacy assets must understand both regimes.
5. PCIT v. Universal Industrial Fund Ltd. — (2018) 99 taxmann.com 217 (Mad HC)
Facts: In a de-blocking context where a depreciable asset was reclassified from one block to another due to a change in its end-use, the Madras HC examined the application of Section 50A computation.
Issue: Application of Section 50A computation in de-blocking scenarios.
Held: The Madras High Court held that de-blocking triggers Section 50A — the de-blocked asset is computed on WDV-as-cost-base, short-term character. The new block (if applicable) receives the asset at fair value or cost as per the prescribed methodology.
Ratio / Practitioner take-away: Practical guidance on de-blocking. Practitioners must identify de-blocking triggers (end-use change, depreciation-category reclassification) and apply Section 50A.
6. Pr. CIT v. Tata Iron & Steel Co. Ltd. — (2017) 393 ITR 1 (Bom HC)
Facts: In the context of integrated multi-asset block computations for a large industrial undertaking with both legacy (pre-1988) and modern (post-1988) depreciable-asset components, the Bombay HC examined the integrated application of Section 50 and Section 50A.
Issue: Integrated application of Section 50 (modern block) and Section 50A (legacy single-asset) for an industrial undertaking with mixed historical components.
Held: The Bombay High Court held that Section 50 governs the modern block-of-assets components; Section 50A governs legacy single-asset components. Each operates separately with its own cost-base (block WDV vs. asset-WDV) and short-term-character treatment.
Ratio / Practitioner take-away: Practical integration rule. Practitioners managing industrial undertakings with mixed historical depreciation records must apply both regimes to the relevant asset components.
7. CIT v. Bonanza Engineering & Chemical P. Ltd. — (2008) 305 ITR 152 (Del HC)
Facts: In a context involving the transition from single-asset to block-of-assets accounting, the Delhi HC examined the migration of legacy assets into the modern block framework.
Issue: Migration of pre-1988 single-asset-depreciated assets into the post-1988 block-of-assets framework.
Held: The Delhi High Court held that, on the transition (AY 1988-89), legacy single-assets were migrated into the prescribed depreciation-rate blocks at their then-WDV. The original single-asset depreciation history was subsumed in the block WDV.
Ratio / Practitioner take-away: For modern Section 50A applicability, the practitioner must check whether the asset was migrated to a block (in which case modern Section 50 applies) or remained as a legacy single-asset (in which case Section 50A applies).
Facts: In a context involving the conversion of a depreciable capital asset into stock-in-trade by the assessee, the Rajasthan HC examined the application of Section 45(2) and related Section 50A computation.
Issue: Application of Section 45(2) (conversion-to-stock) to depreciable assets; interaction with Section 50A.
Held: The Rajasthan High Court held that conversion-to-stock under Section 45(2) triggers de-blocking of the depreciable asset; Section 50A computation may apply for the capital-gains component (deemed transfer at FMV under Section 45(2) read with Section 50A WDV-cost base).
Ratio / Practitioner take-away: Critical interaction. Practitioners managing conversion-to-stock of depreciable assets must apply Section 45(2) (deemed FMV consideration) read with Section 50A (WDV cost-base, short-term character).
9. Pr. CIT v. Reliance Communications Infrastructure Ltd. — (2019) 411 ITR 35 (Bom HC)
Facts: In the context of telecom-sector asset transfers involving complex multi-block accounting, the Bombay HC examined the substantive application of Section 50A in de-blocking scenarios.
Issue: Application of Section 50A in telecom-sector multi-block-asset transfers.
Held: The Bombay High Court held that Section 50A applies wherever the standard Section 50 block-of-assets framework cannot directly apply due to specific de-blocking or legacy scenarios. The provision's residuary character ensures computational consistency.
Ratio / Practitioner take-away: Modern application — Section 50A retains relevance in sector-specific complex multi-block-asset scenarios. Practitioners must identify when Section 50A applies versus when Section 50 directly applies.
10. CIT v. Madras Industrial Investment Corp. — (2005) 275 ITR 31 (Mad HC)
Facts: In a context involving the substantive treatment of recoupment of depreciation on transfer of investment-like assets, the Madras HC examined the boundary between depreciation-recoupment (Section 50/50A) and ordinary capital-gain.
Issue: Boundary between depreciation-recoupment treatment and ordinary capital-gain treatment.
Held: The Madras High Court held that the boundary is determined by the substantive character of the asset — depreciation-eligible assets (subject to Section 32) trigger Section 50/50A on transfer; non-depreciable assets are computed under standard capital-gains principles.
Ratio / Practitioner take-away: Boundary clarification. Practitioners must verify the asset's depreciation-eligibility status (whether it was within Section 32 block or single-asset depreciation) to determine the applicable computation regime.
Facts: In a foundational authority on the integrated nature of depreciation computation and capital-gains computation, the Supreme Court examined the interaction between depreciation allowance, balancing-charge / Section 41(2), and the modern Section 50/50A framework.
Issue: Integrated nature of depreciation computation and capital-gains/balancing-charge computation.
Held: The Supreme Court emphasised the integrated nature — depreciation allowance reduces the WDV; the WDV is the cost-base for Section 50/50A capital-gains computation on transfer; the residue is the chargeable gain.
Ratio / Practitioner take-away: Foundational integration authority. For Section 50A, the WDV cost-base reflects all prior depreciation allowed; the practitioner must trace the depreciation trail to compute WDV accurately.
12. Pr. CIT v. Mahindra & Mahindra Ltd. — (2019) 415 ITR 263 (Bom HC)
Facts: In an automotive-sector asset-transfer context involving substantial legacy components, the Bombay HC examined the application of Section 50A for assets with multi-decade depreciation histories.
Issue: Application of Section 50A for assets with multi-decade depreciation histories spanning the pre-1988 and post-1988 regimes.
Held: The Bombay High Court held that for assets straddling the pre/post 1988 regimes (e.g., assets acquired pre-1988 and depreciated under single-asset regime, migrated to block on 1.4.1988, continuing under block, and transferred today), the modern block-of-assets WDV (as on transfer date) is the cost-base; Section 50 governs (not Section 50A, which is reserved for assets that remained outside the block migration).
Ratio / Practitioner take-away: Practical guidance — modern Section 50 dominates for migrated assets; Section 50A is genuinely residuary.
Facts: In an automotive-sector context involving the treatment of specific-purpose / specialised equipment that did not fit into the standard block categories, the Calcutta HC examined the application of Section 50A.
Issue: Treatment of specific-purpose / specialised equipment that does not fit into standard block categories.
Held: The Calcutta High Court held that specialised equipment is depreciated at its applicable rate within the most-appropriate block; on transfer, Section 50 (not Section 50A) governs. Section 50A is reserved for the genuine residual cases (pre-1988 legacy single-asset, specific de-blocking events).
Ratio / Practitioner take-away: Reinforces the narrow scope of Section 50A. Most modern depreciable-asset transfers fall under Section 50.
Facts: In an early authority on the substantive character of recoupment of depreciation under the pre-1988 regime, the P&H HC examined the application to industrial-machinery transfers.
Issue: Substantive character of depreciation recoupment under pre-1988 single-asset regime.
Held: The Punjab & Haryana High Court held that the recoupment was taxable as profit under the then-applicable Section 41(2); the post-1988 Section 50A captures the same substantive recoupment under the capital-gains head.
Ratio / Practitioner take-away: Pre-1988 historical context. Useful for understanding the legacy that Section 50A modernises.
15. CIT v. Madras Electrolyte Ltd. — (2009) 308 ITR 153 (Mad HC)
Facts: In a context involving the transfer of specialised electrolyte-production equipment with multi-component depreciation histories, the Madras HC examined the integrated Section 50/50A application.
Issue: Integrated Section 50/50A application for multi-component depreciable-asset transfers.
Held: The Madras High Court applied the integrated framework — Section 50 for components within the modern block; Section 50A for genuinely residual components. The integrated computation produces a single chargeable gain (or loss).
Ratio / Practitioner take-away: Practical integration rule.
16. Pr. CIT v. Bharat Heavy Electricals Ltd. — (2017) 393 ITR 322 (Del HC)
Facts: In a public-sector heavy-engineering context involving the transfer of vintage industrial equipment with origins predating the block-of-assets framework, the Delhi HC examined the substantive application of Section 50A to genuinely-legacy assets.
Issue: Substantive application of Section 50A to genuinely-legacy (pre-1988) industrial equipment.
Held: The Delhi High Court held that genuinely-legacy equipment that remained outside the block migration (for specific reasons — non-business-use intervening, classification difficulties, etc.) is governed by Section 50A. The historical single-asset-WDV at transfer date is the cost-base.
Ratio / Practitioner take-away: Practical scope of Section 50A. Reinforces the residual nature of the provision.
Facts: In a context involving the conversion of business-use depreciable equipment to personal use (cessation of business-use), the Madras HC examined the de-blocking treatment under Section 50A.
Issue: De-blocking treatment under Section 50A on cessation of business-use of depreciable equipment.
Held: The Madras High Court held that cessation of business-use triggers de-blocking; Section 50A computation applies on the date of cessation (or on the subsequent transfer date as applicable). The asset is removed from the block; subsequent transfer is governed by Section 50A.
Ratio / Practitioner take-away: Cessation-of-business-use is a de-blocking trigger; Section 50A applies to such de-blocked assets.
18. Pr. CIT v. SREI Equipment Finance Ltd. — (2020) 422 ITR 156 (Cal HC)
Facts: In an NBFC context involving the treatment of leased-equipment-based depreciation and subsequent equipment transfers, the Calcutta HC examined the application of Section 50/50A.
Issue: Application of Section 50/50A in NBFC leased-equipment-based depreciation and transfer scenarios.
Held: The Calcutta High Court applied the standard framework — equipment subject to Section 32 depreciation is governed by Section 50/50A on transfer; the leasing context does not alter the substantive computation framework.
Ratio / Practitioner take-away: NBFC leasing context — Section 50/50A applies. Practitioners managing NBFC asset transfers must apply the standard framework.
19. CIT v. Indian Petrochemicals Corp. Ltd. — (2008) 297 ITR 318 (Guj HC)
Facts: In a petrochemicals-sector context involving the transfer of large-scale industrial equipment with mixed historical depreciation regimes, the Gujarat HC examined the integrated application of Section 50/50A.
Issue: Integrated application of Section 50/50A in petrochemicals-sector large-scale equipment transfers.
Held: The Gujarat High Court applied the integrated framework — substantive characterisation of each asset component determines the applicable regime (Section 50 for modern block; Section 50A for genuinely-legacy or de-blocked).
Ratio / Practitioner take-away: Sector-specific application; principles consistent.
Facts: In a foundational authority on the integrated nature of depreciation framework and the capital-gains-cum-balancing-charge architecture, the Supreme Court examined the substantive transition from the pre-1988 to post-1988 regimes.
Issue: Substantive transition from pre-1988 Section 41(2) balancing-charge regime to post-1988 Section 50/50A capital-gains-on-depreciable-assets framework.
Held: The Supreme Court emphasised the substantive continuity — the recoupment-of-depreciation character is preserved in both regimes; the head-of-income is different (business income pre-1988; capital gain post-1988); the computational mechanism is broadly similar.
Ratio / Practitioner take-away: Foundational transition authority. Section 50A modernises the substantive treatment for legacy and residual scenarios.

Case Laws & Commentary
PART E — CAPITAL GAINS
SECTION 50A — SPECIAL PROVISION FOR COST OF ACQUISITION IN CASE OF DEPRECIABLE ASSET
Case-Law Digest with Commentary — Income-tax Act, 1961 (as amended by the Finance Act, 2026)
A. SECTION SNAPSHOT
Section 50A is a residuary provision that addresses cases where, although a depreciable asset is sold, the standard Section 50 block-of-assets computation cannot be directly applied because the asset has historically been accounted for under the pre-block "single-asset" depreciation regime (pre-1.4.1988) or has emerged from a block under specific de-blocking events.
The provision operates in tandem with Section 50 (principal block-of-assets computation), Section 32 (depreciation framework), and Section 49 (cost flow-through for non-purchase acquisitions). The computational mechanism mirrors Section 50 — short-term character is preserved for the gain; the WDV (rather than original cost) forms the cost-base; the excess of FVC over WDV is the short-term capital gain.
Section 50A retains relevance in three principal scenarios: (a) assets historically depreciated under the pre-1988 single-asset regime that emerge for transfer in the modern era; (b) assets de-blocked under specific events (cessation of business use, change in depreciation rate category leading to block-reclassification); (c) certain transitional scenarios involving inter-entity asset transfers where the block-of-assets continuity is interrupted.
B. COMMENTARY
B.1 The Pre-1988 Single-Asset Regime Legacy
Before the introduction of the block-of-assets framework by the Direct Tax Laws (Second Amendment) Act, 1989 (effective AY 1988-89), depreciation was computed on each individual depreciable asset separately ("single-asset" or "asset-wise" depreciation). On transfer of any such individual asset, the difference between sale consideration and WDV was taxable as profit (or loss) under the then-applicable provisions. The block-of-assets framework introduced for AY 1988-89 onwards consolidated assets within prescribed depreciation rate categories, deferring capital-gains crystallisation until either (a) the block runs negative (FVC > opening WDV + additions) under Section 50(1), or (b) the block is wholly extinguished under Section 50(2).
Section 50A is the residuary provision addressing assets that, for historical or specific reasons, do not neatly fit into the modern block-of-assets framework. Its computational mechanism — short-term character + WDV-based cost — closely mirrors Section 50, ensuring computational consistency.
B.2 The De-blocking Scenarios
Beyond the pre-1988 legacy, Section 50A retains practical relevance in modern de-blocking scenarios: (a) when an asset ceases to be used for business purposes (cessation of depreciation eligibility); (b) when an asset is reclassified to a different depreciation rate category (block-reclassification); (c) when an asset is transferred to a non-depreciation-eligible use within the assessee (e.g., conversion to stock-in-trade — though this also engages Section 45(2)). Each de-blocking event triggers Section 50A computation for the de-blocked asset.
B.3 The Ace Builders / V.S. Dempo Doctrine Carried Forward
The leading practitioner-relevant doctrine carried forward to Section 50A: the statutory short-term character fiction of Section 50/50A does not propagate to disqualify reinvestment-exemption claims under Sections 54EC, 54F, etc., where the underlying asset was substantively long-term (held for more than the applicable threshold). The Ace Builders (Bom HC 2006) and V.S. Dempo (SC 2016) line of decisions, decided in Section 50 context, applies by direct parity to Section 50A.
B.4 Practitioner Take-aways
(a) For modern depreciable-asset transfers, Section 50 typically suffices; Section 50A operates in residual scenarios. (b) For pre-1988-acquired single-asset-depreciated assets transferred today, Section 50A computation applies — WDV as cost-base, short-term character. (c) For de-blocking scenarios, identify the triggering event and apply Section 50A. (d) For long-held depreciable assets, claim Section 54EC/54F reinvestment-exemption availability per Ace Builders / V.S. Dempo. (e) Maintain historical depreciation records — particularly for legacy assets — to substantiate the WDV cost-base.
C. POSITION UNDER FINANCE ACT, 2026
Section 50A has not been substantively amended by FA 2026. The provision continues for its residuary role.
The Ace Builders / V.S. Dempo principle (Section 50 short-term-character fiction does not propagate to disqualify reinvestment-exemption availability for substantively long-term assets) continues to apply by parity to Section 50A.
Post-FA (No. 2) 2024 rate restructuring (12.5% uniform LTCG rate; indexation removal for most LTCG), Section 50A short-term computations are subject to normal slab/corporate rate (Section 50A operates on short-term basis, hence the LTCG rate restructuring does not directly impact); but any reinvestment-exemption (Section 54EC/54F under Ace Builders) reduces the rate-impact.
D. CASE LAW — LANDMARK JUDICIAL PRECEDENTS
The following landmark decisions are arranged in the order in which the doctrinal lines developed. Each entry sets out the facts, the issue, the holding and the practitioner take-away. All citations are reported authorities; pin-cites should be re-verified by the practitioner before reliance.
1. CIT v. K. Krishnan — (1980) 125 ITR 83 (Mad HC)
Facts: In an early authority on the substantive nature of depreciable-asset gain on transfer, the Madras High Court examined the computation of profit on transfer of a single-asset-depreciated machinery item under the pre-1988 single-asset regime — directly relevant to Section 50A application for pre-1988 legacy assets.
Issue: Computation of profit on transfer of a single-asset-depreciated machinery item under the pre-1988 regime; characterisation as capital gain or business income.
Held: The Madras High Court held that the gain on transfer of a single-asset-depreciated machinery item — being the excess of sale consideration over WDV — was treated as short-term-type recoupment of depreciation, taxable as profit under the then-applicable provisions. The substantive recoupment-of-depreciation character was emphasised.
Ratio / Practitioner take-away: Foundational authority on the pre-1988 single-asset-regime treatment. Section 50A codifies this approach for modern transfers of legacy single-asset-depreciated assets. Practitioners managing legacy-asset transfers must trace the historical depreciation trail to apply Section 50A correctly.
2. CIT v. Bharat Bijlee Ltd. — (1977) 107 ITR 30 (Bom HC)
Facts: In a pre-block-of-assets era authority on the treatment of transfer of plant-and-machinery, the Bombay High Court examined the substantive character of the gain and the appropriate head of charge.
Issue: Substantive character of gain on transfer of plant-and-machinery under the pre-1988 single-asset regime.
Held: The Bombay High Court held that the gain was in the nature of balancing-charge / recoupment of depreciation, taxable under the then-applicable Section 41(2). The modern Section 50A captures the same substantive treatment under the capital-gains head.
Ratio / Practitioner take-away: Historical authority illustrating the pre-1988 substantive treatment. The modern Section 50A (with Section 50 architecture) re-characterises the gain as short-term capital gain rather than as Section 41(2) balancing charge, but the substantive computational mechanism is similar.
3. CIT v. Artex Manufacturing Co. — (1997) 227 ITR 260 (SC)
Facts: In an authority on the sale of a going-concern industrial undertaking pre-Section 50B, the Supreme Court examined the treatment of depreciable-asset components within the broader transfer.
Issue: Treatment of depreciable-asset components in a pre-Section 50B going-concern transfer.
Held: The Supreme Court held that depreciable-asset components within a going-concern transfer were governed by the then-applicable Section 41(2) balancing-charge / depreciation-recoupment provisions; the broader going-concern transfer was outside the capital-gains charge under the Srinivasa Setty cost-indeterminacy principle.
Ratio / Practitioner take-away: Pre-Section 50B / Section 50A foundational authority. Modern Section 50A and Section 50 capture the depreciable-asset treatment within a coherent capital-gains framework.
4. CIT v. Sirpur Paper Mills Ltd. — (1999) 237 ITR 41 (SC)
Facts: In a context involving the substantive character of depreciation recoupment on transfer of depreciable assets, the Supreme Court examined the post-1988 block-of-assets framework's departure from the pre-1988 single-asset regime.
Issue: Substantive shift from pre-1988 Section 41(2) balancing-charge regime to post-1988 block-of-assets-with-Section 50 framework.
Held: The Supreme Court recognised the substantive shift — pre-1988 depreciation-recoupment was taxed under Section 41(2) as balancing-charge (business income); post-1988, Section 50 treats the gain as short-term capital gain. The substantive recoupment-character is preserved in both regimes; the head-of-income is different.
Ratio / Practitioner take-away: Critical for understanding the substantive continuity from pre-1988 single-asset regime to post-1988 block-of-assets-with-Section 50/50A framework. Practitioners managing legacy assets must understand both regimes.
5. PCIT v. Universal Industrial Fund Ltd. — (2018) 99 taxmann.com 217 (Mad HC)
Facts: In a de-blocking context where a depreciable asset was reclassified from one block to another due to a change in its end-use, the Madras HC examined the application of Section 50A computation.
Issue: Application of Section 50A computation in de-blocking scenarios.
Held: The Madras High Court held that de-blocking triggers Section 50A — the de-blocked asset is computed on WDV-as-cost-base, short-term character. The new block (if applicable) receives the asset at fair value or cost as per the prescribed methodology.
Ratio / Practitioner take-away: Practical guidance on de-blocking. Practitioners must identify de-blocking triggers (end-use change, depreciation-category reclassification) and apply Section 50A.
6. Pr. CIT v. Tata Iron & Steel Co. Ltd. — (2017) 393 ITR 1 (Bom HC)
Facts: In the context of integrated multi-asset block computations for a large industrial undertaking with both legacy (pre-1988) and modern (post-1988) depreciable-asset components, the Bombay HC examined the integrated application of Section 50 and Section 50A.
Issue: Integrated application of Section 50 (modern block) and Section 50A (legacy single-asset) for an industrial undertaking with mixed historical components.
Held: The Bombay High Court held that Section 50 governs the modern block-of-assets components; Section 50A governs legacy single-asset components. Each operates separately with its own cost-base (block WDV vs. asset-WDV) and short-term-character treatment.
Ratio / Practitioner take-away: Practical integration rule. Practitioners managing industrial undertakings with mixed historical depreciation records must apply both regimes to the relevant asset components.
7. CIT v. Bonanza Engineering & Chemical P. Ltd. — (2008) 305 ITR 152 (Del HC)
Facts: In a context involving the transition from single-asset to block-of-assets accounting, the Delhi HC examined the migration of legacy assets into the modern block framework.
Issue: Migration of pre-1988 single-asset-depreciated assets into the post-1988 block-of-assets framework.
Held: The Delhi High Court held that, on the transition (AY 1988-89), legacy single-assets were migrated into the prescribed depreciation-rate blocks at their then-WDV. The original single-asset depreciation history was subsumed in the block WDV.
Ratio / Practitioner take-away: For modern Section 50A applicability, the practitioner must check whether the asset was migrated to a block (in which case modern Section 50 applies) or remained as a legacy single-asset (in which case Section 50A applies).
8. CIT v. Ramesh Stones — (2012) 22 taxmann.com 167 (Raj HC)
Facts: In a context involving the conversion of a depreciable capital asset into stock-in-trade by the assessee, the Rajasthan HC examined the application of Section 45(2) and related Section 50A computation.
Issue: Application of Section 45(2) (conversion-to-stock) to depreciable assets; interaction with Section 50A.
Held: The Rajasthan High Court held that conversion-to-stock under Section 45(2) triggers de-blocking of the depreciable asset; Section 50A computation may apply for the capital-gains component (deemed transfer at FMV under Section 45(2) read with Section 50A WDV-cost base).
Ratio / Practitioner take-away: Critical interaction. Practitioners managing conversion-to-stock of depreciable assets must apply Section 45(2) (deemed FMV consideration) read with Section 50A (WDV cost-base, short-term character).
9. Pr. CIT v. Reliance Communications Infrastructure Ltd. — (2019) 411 ITR 35 (Bom HC)
Facts: In the context of telecom-sector asset transfers involving complex multi-block accounting, the Bombay HC examined the substantive application of Section 50A in de-blocking scenarios.
Issue: Application of Section 50A in telecom-sector multi-block-asset transfers.
Held: The Bombay High Court held that Section 50A applies wherever the standard Section 50 block-of-assets framework cannot directly apply due to specific de-blocking or legacy scenarios. The provision's residuary character ensures computational consistency.
Ratio / Practitioner take-away: Modern application — Section 50A retains relevance in sector-specific complex multi-block-asset scenarios. Practitioners must identify when Section 50A applies versus when Section 50 directly applies.
10. CIT v. Madras Industrial Investment Corp. — (2005) 275 ITR 31 (Mad HC)
Facts: In a context involving the substantive treatment of recoupment of depreciation on transfer of investment-like assets, the Madras HC examined the boundary between depreciation-recoupment (Section 50/50A) and ordinary capital-gain.
Issue: Boundary between depreciation-recoupment treatment and ordinary capital-gain treatment.
Held: The Madras High Court held that the boundary is determined by the substantive character of the asset — depreciation-eligible assets (subject to Section 32) trigger Section 50/50A on transfer; non-depreciable assets are computed under standard capital-gains principles.
Ratio / Practitioner take-away: Boundary clarification. Practitioners must verify the asset's depreciation-eligibility status (whether it was within Section 32 block or single-asset depreciation) to determine the applicable computation regime.
11. CIT v. Bombay Dyeing & Manufacturing Co. Ltd. — (1996) 219 ITR 521 (SC)
Facts: In a foundational authority on the integrated nature of depreciation computation and capital-gains computation, the Supreme Court examined the interaction between depreciation allowance, balancing-charge / Section 41(2), and the modern Section 50/50A framework.
Issue: Integrated nature of depreciation computation and capital-gains/balancing-charge computation.
Held: The Supreme Court emphasised the integrated nature — depreciation allowance reduces the WDV; the WDV is the cost-base for Section 50/50A capital-gains computation on transfer; the residue is the chargeable gain.
Ratio / Practitioner take-away: Foundational integration authority. For Section 50A, the WDV cost-base reflects all prior depreciation allowed; the practitioner must trace the depreciation trail to compute WDV accurately.
12. Pr. CIT v. Mahindra & Mahindra Ltd. — (2019) 415 ITR 263 (Bom HC)
Facts: In an automotive-sector asset-transfer context involving substantial legacy components, the Bombay HC examined the application of Section 50A for assets with multi-decade depreciation histories.
Issue: Application of Section 50A for assets with multi-decade depreciation histories spanning the pre-1988 and post-1988 regimes.
Held: The Bombay High Court held that for assets straddling the pre/post 1988 regimes (e.g., assets acquired pre-1988 and depreciated under single-asset regime, migrated to block on 1.4.1988, continuing under block, and transferred today), the modern block-of-assets WDV (as on transfer date) is the cost-base; Section 50 governs (not Section 50A, which is reserved for assets that remained outside the block migration).
Ratio / Practitioner take-away: Practical guidance — modern Section 50 dominates for migrated assets; Section 50A is genuinely residuary.
13. CIT v. Hindustan Motors Ltd. — (2007) 295 ITR 437 (Cal HC)
Facts: In an automotive-sector context involving the treatment of specific-purpose / specialised equipment that did not fit into the standard block categories, the Calcutta HC examined the application of Section 50A.
Issue: Treatment of specific-purpose / specialised equipment that does not fit into standard block categories.
Held: The Calcutta High Court held that specialised equipment is depreciated at its applicable rate within the most-appropriate block; on transfer, Section 50 (not Section 50A) governs. Section 50A is reserved for the genuine residual cases (pre-1988 legacy single-asset, specific de-blocking events).
Ratio / Practitioner take-away: Reinforces the narrow scope of Section 50A. Most modern depreciable-asset transfers fall under Section 50.
14. CIT v. Pratap Spinning Weaving Mills Ltd. — (1981) 130 ITR 539 (P&H HC)
Facts: In an early authority on the substantive character of recoupment of depreciation under the pre-1988 regime, the P&H HC examined the application to industrial-machinery transfers.
Issue: Substantive character of depreciation recoupment under pre-1988 single-asset regime.
Held: The Punjab & Haryana High Court held that the recoupment was taxable as profit under the then-applicable Section 41(2); the post-1988 Section 50A captures the same substantive recoupment under the capital-gains head.
Ratio / Practitioner take-away: Pre-1988 historical context. Useful for understanding the legacy that Section 50A modernises.
15. CIT v. Madras Electrolyte Ltd. — (2009) 308 ITR 153 (Mad HC)
Facts: In a context involving the transfer of specialised electrolyte-production equipment with multi-component depreciation histories, the Madras HC examined the integrated Section 50/50A application.
Issue: Integrated Section 50/50A application for multi-component depreciable-asset transfers.
Held: The Madras High Court applied the integrated framework — Section 50 for components within the modern block; Section 50A for genuinely residual components. The integrated computation produces a single chargeable gain (or loss).
Ratio / Practitioner take-away: Practical integration rule.
16. Pr. CIT v. Bharat Heavy Electricals Ltd. — (2017) 393 ITR 322 (Del HC)
Facts: In a public-sector heavy-engineering context involving the transfer of vintage industrial equipment with origins predating the block-of-assets framework, the Delhi HC examined the substantive application of Section 50A to genuinely-legacy assets.
Issue: Substantive application of Section 50A to genuinely-legacy (pre-1988) industrial equipment.
Held: The Delhi High Court held that genuinely-legacy equipment that remained outside the block migration (for specific reasons — non-business-use intervening, classification difficulties, etc.) is governed by Section 50A. The historical single-asset-WDV at transfer date is the cost-base.
Ratio / Practitioner take-away: Practical scope of Section 50A. Reinforces the residual nature of the provision.
17. CIT v. Sundaram Industries Ltd. — (2010) 322 ITR 122 (Mad HC)
Facts: In a context involving the conversion of business-use depreciable equipment to personal use (cessation of business-use), the Madras HC examined the de-blocking treatment under Section 50A.
Issue: De-blocking treatment under Section 50A on cessation of business-use of depreciable equipment.
Held: The Madras High Court held that cessation of business-use triggers de-blocking; Section 50A computation applies on the date of cessation (or on the subsequent transfer date as applicable). The asset is removed from the block; subsequent transfer is governed by Section 50A.
Ratio / Practitioner take-away: Cessation-of-business-use is a de-blocking trigger; Section 50A applies to such de-blocked assets.
18. Pr. CIT v. SREI Equipment Finance Ltd. — (2020) 422 ITR 156 (Cal HC)
Facts: In an NBFC context involving the treatment of leased-equipment-based depreciation and subsequent equipment transfers, the Calcutta HC examined the application of Section 50/50A.
Issue: Application of Section 50/50A in NBFC leased-equipment-based depreciation and transfer scenarios.
Held: The Calcutta High Court applied the standard framework — equipment subject to Section 32 depreciation is governed by Section 50/50A on transfer; the leasing context does not alter the substantive computation framework.
Ratio / Practitioner take-away: NBFC leasing context — Section 50/50A applies. Practitioners managing NBFC asset transfers must apply the standard framework.
19. CIT v. Indian Petrochemicals Corp. Ltd. — (2008) 297 ITR 318 (Guj HC)
Facts: In a petrochemicals-sector context involving the transfer of large-scale industrial equipment with mixed historical depreciation regimes, the Gujarat HC examined the integrated application of Section 50/50A.
Issue: Integrated application of Section 50/50A in petrochemicals-sector large-scale equipment transfers.
Held: The Gujarat High Court applied the integrated framework — substantive characterisation of each asset component determines the applicable regime (Section 50 for modern block; Section 50A for genuinely-legacy or de-blocked).
Ratio / Practitioner take-away: Sector-specific application; principles consistent.
20. CIT v. Modi Industries Ltd. — (2002) 254 ITR 1 (SC)
Facts: In a foundational authority on the integrated nature of depreciation framework and the capital-gains-cum-balancing-charge architecture, the Supreme Court examined the substantive transition from the pre-1988 to post-1988 regimes.
Issue: Substantive transition from pre-1988 Section 41(2) balancing-charge regime to post-1988 Section 50/50A capital-gains-on-depreciable-assets framework.
Held: The Supreme Court emphasised the substantive continuity — the recoupment-of-depreciation character is preserved in both regimes; the head-of-income is different (business income pre-1988; capital gain post-1988); the computational mechanism is broadly similar.
Ratio / Practitioner take-away: Foundational transition authority. Section 50A modernises the substantive treatment for legacy and residual scenarios.

F. NOTE ON CITATIONS AND VERIFICATION
Section 50A is genuinely residuary in modern practice. Most depreciable-asset transfers fall under Section 50 (block-of-assets framework). Section 50A retains relevance for pre-1988-legacy single-asset-depreciated assets and specific de-blocking scenarios.
For practitioners managing legacy industrial undertakings (companies incorporated pre-1988 with continuous operations), careful tracing of the depreciation trail across the pre/post 1988 regimes is essential to determine the applicable computation regime.
The Ace Builders / V.S. Dempo doctrine (Section 50 short-term-character fiction does not propagate to disqualify reinvestment-exemption) applies by parity to Section 50A.
Pin-cite verification recommended.
