Section 48 is the computational machinery for capital gains. Capital gain = full value of consideration LESS (transfer expenditure + cost of acquisition + cost of improvement). For LONG-TERM capital assets, the costs are inflated using the Cost Inflation Index (second proviso) — but only for the 'old' rate-regime; STT-paid equity LTCG (s. 112A) and FA 2024-rate-changed assets do not get indexation. The provisos handle special asset classes — NR shares/debentures, STT-paid equity (grandfathered to 31-1-2018), bonds/debentures, FA 2018-specified ETF/IDF, etc.
Historical context / FA amendment trail
Substantively amended over many FAs. Major reforms: FA 1992 (indexation introduced); FA 1998 (NR foreign-currency proviso); FA 2018 (STT-paid LTCG charge under s. 112A + grandfathering proviso to s. 48); FA 2024 (LTCG rate reduced to 12.5% + indexation REMOVED for most assets effective 23-7-2024 — with grandfathering option for immovable property held before 23-7-2024). FA 2025 — minor clarifications. The Cost Inflation Index for FY 2024-25 = 363 (Notification 95/2024).
Operative consequences
• Core formula: capital gain = full value of consideration - (transfer expenditure + cost + improvement).
• Long-term: indexation under second proviso (except STT-paid equity post-FA 2018 + post-23-7-2024 reform).
• STT-paid equity LTCG (s. 112A): fourth proviso grandfathering — cost = higher of actual + 31-1-2018 FMV.
• Post-FA 2024 (23-7-2024): LTCG rate uniformly 12.5% across most assets; indexation REMOVED except for grandfathered immovable property held before 23-7-2024.
• NR shares/debentures: foreign-currency computation under first proviso (Rule 115A).
• Bonds / debentures: indexation NOT available (sixth proviso).
• FA 2018 fifth proviso: ETF/IDF/AIF FMV-as-acquired-cost.
• DTAA Article 13: treaty residence-state may have exclusive taxation right; more-beneficial principle.
Case Laws & Commentary
PART E — CAPITAL GAINS
SECTION 48 — MODE OF COMPUTATION OF CAPITAL GAINS
Case-Law Digest with Commentary — Income-tax Act, 1961 (as amended by the Finance Act, 2026)
A. SECTION SNAPSHOT
Section 48 is the computation machinery for capital gains. The basic formula is: Capital Gain = Full Value of Consideration − (Cost of Acquisition + Cost of Improvement + Expenditure incurred wholly and exclusively in connection with the transfer). For long-term capital assets, the second proviso permits substitution of cost of acquisition / improvement by the indexed cost (until removed/restricted by FA 2024/FA 2026 for most asset classes).
Three provisos provide special computation rules: (a) First proviso — non-resident shareholders' transfer of Indian-company shares/debentures: forex-adjusted-cost mechanism using prescribed conversion methodology (Rule 115A); (b) Second proviso — long-term capital assets generally: indexation of cost of acquisition and improvement using Cost Inflation Index (with carve-outs in fifth proviso); (c) Third proviso — no indexation on bonds/debentures (other than capital indexed bonds and Sovereign Gold Bonds issued by RBI).
Post-FA (No. 2) 2024 (and continued by FA 2026), indexation has been removed for most long-term capital assets transferred on or after 23 July 2024; the LTCG rate has been rationalised to 12.5% (Section 112/112A). Limited indexation continues for resident individuals/HUFs on transfer of land/building acquired before 23 July 2024 (special grandfathering proviso to Section 112). Practitioners must apply the appropriate computation rule based on transfer date and assessee category.
B. COMMENTARY
B.1 The Three Computational Inputs — Strict Construction
Section 48 admits only three deductions from FVC: (i) cost of acquisition, (ii) cost of improvement, and (iii) expenditure wholly and exclusively in connection with transfer. The list is exhaustive — no other deduction is permitted, however reasonable or commercially justified. The Supreme Court in HCL Comnet Systems (2008) reaffirmed this strict-construction approach; reasonable items like litigation expenses, broker's commission, valuation fees clearly fall within (iii), but extraneous items (employee severance, post-transfer warranty provisioning, etc.) do not, however connected with the broader commercial deal.
B.2 Indexation — Second Proviso and the FA 2024/2026 Re-architecture
The second proviso to Section 48 historically permitted substitution of indexed cost — a relief intended to neutralise inflation's eroding effect on the real cost basis. The Cost Inflation Index (CII) is notified annually by CBDT. FA (No. 2) 2024 removed indexation for most long-term assets transferred on or after 23 July 2024 (with the corresponding rate drop to 12.5%). FA 2026 has carried this architecture forward with refinements. A grandfathering carve-out under the proviso to Section 112 preserves indexation for resident individuals/HUFs on land/building acquired before 23 July 2024 — they may compute LTCG under either (a) 20% with indexation or (b) 12.5% without indexation, whichever is lower.
B.3 First Proviso — Non-Resident Forex Adjustment
Where a non-resident transfers shares or debentures of an Indian company, the first proviso requires that the cost, expenditure on transfer, and FVC all be converted to the same foreign currency in which the original purchase was made (using prescribed buying/selling rates per Rule 115A) and that the capital gain be computed in that foreign currency and re-translated. This mechanism insulates the non-resident from rupee-depreciation distortions of the real capital gain. Indexation under the second proviso is NOT available where the first proviso applies (sixth proviso).
B.4 "In Connection With the Transfer" — Expenditure Test
The phrase "wholly and exclusively in connection with the transfer" has been construed strictly. Broker's commission, valuation fees, registration costs, stamp duty, legal fees for the conveyance — all are clearly within the test. However, expenditure incurred before the transfer (search costs, due diligence by buyer reimbursed by seller), expenditure incurred after the transfer (post-closing adjustments, indemnity payments), and general business expenditure not tied to the specific transfer are typically disallowed. The Bombay HC in Shakuntala Kantilal (1991) and several decisions on litigation-cost-deductions provide the leading guidance.
B.5 Cost of Improvement — Sections 48 and 55(1)(b)
Cost of improvement is defined under Section 55(1)(b) — capital expenditure incurred in making additions or alterations to the capital asset (for assets other than goodwill, trade marks, etc., where statutory rules apply). Routine maintenance and current repairs (allowable under other heads) are excluded. The pre-1.4.2001 cost of improvement is generally ignored unless the assessee opts for FMV-as-on-1-4-2001 under Section 55(2)(b); post-1.4.2001 costs of improvement are added subject to indexation (where indexation is available).
B.6 Practitioner Take-aways
(a) Build the cost basis methodically — purchase price + stamp/registration + brokerage at purchase + cost of improvement (post-1.4.2001) + transfer-related expenditure. (b) For long-term assets transferred on or after 23 July 2024, apply the 12.5% rate without indexation (subject to grandfathering for resident individuals/HUFs on pre-23-July-2024 land/building). (c) For non-resident shareholders of Indian companies, mandatorily apply the first proviso forex-adjustment mechanism. (d) Document expenditure on transfer contemporaneously — invoices, bank traces, legal opinions — for evidentiary purposes.
C. POSITION UNDER FINANCE ACT, 2026
FA (No. 2) 2024, effective 23 July 2024, fundamentally restructured the long-term capital-gains regime — removed indexation for most LTCG and rationalised the rate to 12.5% (Section 112). The grandfathering proviso to Section 112 preserves the 20%-with-indexation option for resident individuals/HUFs on land/building acquired before 23 July 2024. Section 112A (listed equity, equity-mutual funds, business trust units) charges 12.5% above the threshold (₹1,25,000 from FY 2024-25 onwards). Section 111A (short-term gain on equity) charges 20% (increased from 15% by FA (No. 2) 2024).
FA 2026 has not further amended Section 48 substantively. The first proviso (non-resident forex adjustment), the second proviso (indexation — now largely circumscribed), and the third proviso (no indexation on bonds/debentures) continue in force. Practitioners advising on transfers effected on or after 23 July 2024 must apply the post-FA 2024 framework; transfers prior to that date are governed by the pre-amendment regime.
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.
Issue: Whether subsequently-paid amounts towards the asset (post-purchase) form part of cost.
Held: Supreme Court held that all amounts paid/payable as consideration for the acquisition — even if paid post-purchase — form part of cost of acquisition; subsequent improvements form cost of improvement. Cost of acquisition is the total amount paid to acquire title to the asset.
Ratio / Practitioner take-away: Foundational authority on the breadth of "cost of acquisition" — including deferred payments, instalments, contingent considerations once crystallised.
Facts: Payment by seller to a third party to clear an encumbrance, in order to complete the sale.
Issue: Whether the encumbrance-clearance payment is deductible as expenditure "in connection with the transfer" under Section 48.
Held: Bombay High Court held that payments necessary to give the buyer clean title — clearing encumbrances, settling third-party claims, removing impediments to conveyance — are wholly and exclusively in connection with the transfer and deductible under Section 48.
Ratio / Practitioner take-away: Liberal interpretation of "in connection with the transfer". Practitioners cite this where payments to encumbrance-holders are made as part of the closing waterfall.
4. CIT v. HCL Comnet Systems & Services Ltd. — (2008) 305 ITR 409 (SC)
Facts: Provision-related expenditure was sought to be set off against capital gains.
Issue: Strict-construction of Section 48 deductions.
Held: Supreme Court held that Section 48 admits only the three enumerated deductions; the list is exhaustive and no equitable expansion is permitted.
Ratio / Practitioner take-away: Foundational strict-construction authority. Practitioners may not import deductions from other heads (e.g., Section 37 business expenditure) into Section 48.
5. CIT v. Sun Engineering Works (P) Ltd. — (1992) 198 ITR 297 (SC)
Facts: Cognate context on the relation between computation provisions and charging provisions.
Issue: Integrated reading of charging and computation provisions.
Held: Charging and computation provisions form an integrated whole; one cannot operate without the other.
Ratio / Practitioner take-away: Reinforces the Srinivasa Setty principle. Useful in cases of computational uncertainty.
Facts: Cost of clearance of mortgage created post-acquisition by the assessee himself.
Issue: Whether such mortgage-clearance payment is deductible under Section 48.
Held: Supreme Court held that where the mortgage was created by the assessee himself after acquisition, the clearance payment is not deductible — it is in the nature of repayment of own debt, not expenditure in connection with the transfer. Distinguished from cases where the encumbrance pre-existed the assessee's ownership (in which case the payment is deductible to obtain clear title).
Ratio / Practitioner take-away: Critical distinction — pre-acquisition encumbrance clearance = deductible; post-acquisition self-created encumbrance clearance = not deductible. Practitioners must trace the origin of the encumbrance.
Facts: Estate duty paid by the legatee on inheritance of immovable property, which was subsequently sold.
Issue: Whether estate duty paid forms part of cost of acquisition or is deductible as expenditure on transfer.
Held: Supreme Court held that estate duty paid is neither cost of acquisition (it is a tax, not consideration) nor expenditure on transfer (it is connected with succession, not with the transfer). No deduction available under Section 48.
Ratio / Practitioner take-away: Strict reading of the three enumerated heads. Practitioners cannot deduct succession-related taxes from capital gains computation.
Facts: Cost of improvement claim on agricultural land subsequently converted to non-agricultural and sold.
Issue: Whether agricultural improvement costs incurred during agricultural-use period qualify as cost of improvement under Section 55(1)(b).
Held: Madras High Court held that capital improvements to the land (e.g., levelling, terracing, sinking borewells) qualify as cost of improvement irrespective of the then-classification of the land — so long as they enhanced the capital value.
Ratio / Practitioner take-away: Liberal interpretation of cost of improvement. Practitioners should maintain contemporaneous documentation of all capital improvements throughout the holding period.
Facts: Pre-1.4.2001 cost of improvement on long-held immovable property.
Issue: Treatment of pre-1.4.2001 cost of improvement where FMV-as-on-1-4-2001 election is made.
Held: Madras High Court held that where the FMV-as-on-1-4-2001 option is exercised under Section 55(2)(b), pre-1.4.2001 cost of improvement is subsumed in the FMV (which reflects all improvements up to that date); only post-1.4.2001 cost of improvement is separately added.
Ratio / Practitioner take-away: Settles the double-counting issue. Practitioners electing FMV-as-on-1-4-2001 must not separately add pre-1.4.2001 improvements.
Facts: Computation of capital gain on transfer of shares; cost basis and expenditure-on-transfer claims.
Issue: Allowability of advisory fees and arrangement fees paid in connection with the transfer.
Held: Bombay High Court allowed advisory and arrangement fees as wholly and exclusively in connection with the transfer — Section 48(iii) deduction.
Ratio / Practitioner take-away: Useful practitioner authority. Advisory/arrangement/M&A success fees are typically deductible if invoiced specifically for the transfer.
Facts: Brokerage paid on property sale; deductibility under Section 48.
Issue: Whether brokerage paid to property agent forms allowable expenditure on transfer.
Held: Delhi High Court held that brokerage paid to enable the transfer is squarely within Section 48(iii); the deduction is allowable on production of evidence (invoice, payment trace).
Ratio / Practitioner take-away: Standard practitioner-friendly authority on transfer-broker expenses.
Facts: Holding-period computation for under-construction flat; date of allotment versus date of registration.
Issue: Effect of allotment date on holding-period characterisation and indexation start-point.
Held: Bombay High Court held that the holding period runs from the date of allotment (when the right to obtain conveyance is acquired) — supporting long-term characterisation and earlier indexation start. CBDT Circular Nos. 471 and 672 are recognised.
Ratio / Practitioner take-away: Foundational practitioner authority on holding-period for under-construction flats. Often cited in indexation disputes.
Facts: Surrender of tenancy rights — cost of acquisition indeterminate.
Issue: Application of Srinivasa Setty to tenancy-rights surrender.
Held: No determinate cost; charging section fails. (Section 55(2)(a) now deems nil cost for tenancy rights — neutralising this escape for post-amendment transactions.)
Ratio / Practitioner take-away: Applied Srinivasa Setty; legislative response in Section 55(2)(a). Practitioners now use Section 55(2)(a) deemed-nil-cost framework for tenancy-rights computations.
Facts: Legal expenses incurred in defending title to capital asset prior to transfer.
Issue: Deductibility of such legal expenses under Section 48.
Held: Rajasthan High Court held that pre-transfer legal expenses incurred to perfect title — where necessary to enable the transfer — are deductible under Section 48(iii). Mere defence of title in unrelated litigation, however, is not.
Ratio / Practitioner take-away: Fact-sensitive standard. The litigation must be substantively connected to the transfer to qualify.
Facts: Cost of acquisition of contractual rights (right to conveyance under agreement to sell).
Issue: Cost of acquisition of rights that arise from contract, not paid-up consideration.
Held: Bombay High Court held that contractual rights are capital assets; the amounts paid under the agreement (earnest money, instalments) form the cost of acquisition. Where no separate cost was paid for the right itself, the issue collapses into the Srinivasa Setty doctrine.
Ratio / Practitioner take-away: Cost computation for chose-in-action transfers. Practitioners must trace the actual cash outflow to compute cost.
Issue: Whether artificial cost-padding via colourable devices is permissible.
Held: Supreme Court held that colourable devices are to be disregarded; the genuine cost forms the basis of Section 48 computation.
Ratio / Practitioner take-away: Anti-avoidance principle in cost-computation. The breadth was later read down by Azadi Bachao Andolan (2003) and Vodafone (2012), restoring the genuine-planning protection.
Ratio / Practitioner take-away: Triggered the Section 55(2)(a) deeming amendments. Practitioners should now apply the nil-cost rule for self-generated intangibles covered by Section 55(2)(a).
Held: Court applied a methodical Section 48 calculation — FVC less indexed cost less expenditure in connection with transfer. Practitioner-friendly approach to commercial expenses.
Ratio / Practitioner take-away: Useful template for Section 48 application in share-sale assessments.

The FA 2024 rate restructuring (12.5% uniform LTCG; removal of indexation for most assets) is the single most significant change to the Section 48 computational landscape in two decades. Many pre-FA 2024 case-law citations dealing with the 20%-with-indexation rate continue to be relevant for substantive principles but the rate-and-indexation conclusions must be re-read in light of the new framework.
For specific asset categories (debt MFs, market-linked debentures under Section 50AA, slump sale under Section 50B, depreciable assets under Section 50, etc.), separate computation rules apply that override or modify the basic Section 48 framework.
Function in the statutory architecture
Section 48 is the computational machinery for capital gains. Capital gain = full value of consideration LESS (transfer expenditure + cost of acquisition + cost of improvement). For LONG-TERM capital assets, the costs are inflated using the Cost Inflation Index (second proviso) — but only for the 'old' rate-regime; STT-paid equity LTCG (s. 112A) and FA 2024-rate-changed assets do not get indexation. The provisos handle special asset classes — NR shares/debentures, STT-paid equity (grandfathered to 31-1-2018), bonds/debentures, FA 2018-specified ETF/IDF, etc.
Historical context / FA amendment trail
Substantively amended over many FAs. Major reforms: FA 1992 (indexation introduced); FA 1998 (NR foreign-currency proviso); FA 2018 (STT-paid LTCG charge under s. 112A + grandfathering proviso to s. 48); FA 2024 (LTCG rate reduced to 12.5% + indexation REMOVED for most assets effective 23-7-2024 — with grandfathering option for immovable property held before 23-7-2024). FA 2025 — minor clarifications. The Cost Inflation Index for FY 2024-25 = 363 (Notification 95/2024).
Operative consequences
• Core formula: capital gain = full value of consideration - (transfer expenditure + cost + improvement).
• Long-term: indexation under second proviso (except STT-paid equity post-FA 2018 + post-23-7-2024 reform).
• STT-paid equity LTCG (s. 112A): fourth proviso grandfathering — cost = higher of actual + 31-1-2018 FMV.
• Post-FA 2024 (23-7-2024): LTCG rate uniformly 12.5% across most assets; indexation REMOVED except for grandfathered immovable property held before 23-7-2024.
• NR shares/debentures: foreign-currency computation under first proviso (Rule 115A).
• Bonds / debentures: indexation NOT available (sixth proviso).
• FA 2018 fifth proviso: ETF/IDF/AIF FMV-as-acquired-cost.
• DTAA Article 13: treaty residence-state may have exclusive taxation right; more-beneficial principle.
Case Laws & Commentary
PART E — CAPITAL GAINS
SECTION 48 — MODE OF COMPUTATION OF CAPITAL GAINS
Case-Law Digest with Commentary — Income-tax Act, 1961 (as amended by the Finance Act, 2026)
A. SECTION SNAPSHOT
Section 48 is the computation machinery for capital gains. The basic formula is: Capital Gain = Full Value of Consideration − (Cost of Acquisition + Cost of Improvement + Expenditure incurred wholly and exclusively in connection with the transfer). For long-term capital assets, the second proviso permits substitution of cost of acquisition / improvement by the indexed cost (until removed/restricted by FA 2024/FA 2026 for most asset classes).
Three provisos provide special computation rules: (a) First proviso — non-resident shareholders' transfer of Indian-company shares/debentures: forex-adjusted-cost mechanism using prescribed conversion methodology (Rule 115A); (b) Second proviso — long-term capital assets generally: indexation of cost of acquisition and improvement using Cost Inflation Index (with carve-outs in fifth proviso); (c) Third proviso — no indexation on bonds/debentures (other than capital indexed bonds and Sovereign Gold Bonds issued by RBI).
Post-FA (No. 2) 2024 (and continued by FA 2026), indexation has been removed for most long-term capital assets transferred on or after 23 July 2024; the LTCG rate has been rationalised to 12.5% (Section 112/112A). Limited indexation continues for resident individuals/HUFs on transfer of land/building acquired before 23 July 2024 (special grandfathering proviso to Section 112). Practitioners must apply the appropriate computation rule based on transfer date and assessee category.
B. COMMENTARY
B.1 The Three Computational Inputs — Strict Construction
Section 48 admits only three deductions from FVC: (i) cost of acquisition, (ii) cost of improvement, and (iii) expenditure wholly and exclusively in connection with transfer. The list is exhaustive — no other deduction is permitted, however reasonable or commercially justified. The Supreme Court in HCL Comnet Systems (2008) reaffirmed this strict-construction approach; reasonable items like litigation expenses, broker's commission, valuation fees clearly fall within (iii), but extraneous items (employee severance, post-transfer warranty provisioning, etc.) do not, however connected with the broader commercial deal.
B.2 Indexation — Second Proviso and the FA 2024/2026 Re-architecture
The second proviso to Section 48 historically permitted substitution of indexed cost — a relief intended to neutralise inflation's eroding effect on the real cost basis. The Cost Inflation Index (CII) is notified annually by CBDT. FA (No. 2) 2024 removed indexation for most long-term assets transferred on or after 23 July 2024 (with the corresponding rate drop to 12.5%). FA 2026 has carried this architecture forward with refinements. A grandfathering carve-out under the proviso to Section 112 preserves indexation for resident individuals/HUFs on land/building acquired before 23 July 2024 — they may compute LTCG under either (a) 20% with indexation or (b) 12.5% without indexation, whichever is lower.
B.3 First Proviso — Non-Resident Forex Adjustment
Where a non-resident transfers shares or debentures of an Indian company, the first proviso requires that the cost, expenditure on transfer, and FVC all be converted to the same foreign currency in which the original purchase was made (using prescribed buying/selling rates per Rule 115A) and that the capital gain be computed in that foreign currency and re-translated. This mechanism insulates the non-resident from rupee-depreciation distortions of the real capital gain. Indexation under the second proviso is NOT available where the first proviso applies (sixth proviso).
B.4 "In Connection With the Transfer" — Expenditure Test
The phrase "wholly and exclusively in connection with the transfer" has been construed strictly. Broker's commission, valuation fees, registration costs, stamp duty, legal fees for the conveyance — all are clearly within the test. However, expenditure incurred before the transfer (search costs, due diligence by buyer reimbursed by seller), expenditure incurred after the transfer (post-closing adjustments, indemnity payments), and general business expenditure not tied to the specific transfer are typically disallowed. The Bombay HC in Shakuntala Kantilal (1991) and several decisions on litigation-cost-deductions provide the leading guidance.
B.5 Cost of Improvement — Sections 48 and 55(1)(b)
Cost of improvement is defined under Section 55(1)(b) — capital expenditure incurred in making additions or alterations to the capital asset (for assets other than goodwill, trade marks, etc., where statutory rules apply). Routine maintenance and current repairs (allowable under other heads) are excluded. The pre-1.4.2001 cost of improvement is generally ignored unless the assessee opts for FMV-as-on-1-4-2001 under Section 55(2)(b); post-1.4.2001 costs of improvement are added subject to indexation (where indexation is available).
B.6 Practitioner Take-aways
(a) Build the cost basis methodically — purchase price + stamp/registration + brokerage at purchase + cost of improvement (post-1.4.2001) + transfer-related expenditure. (b) For long-term assets transferred on or after 23 July 2024, apply the 12.5% rate without indexation (subject to grandfathering for resident individuals/HUFs on pre-23-July-2024 land/building). (c) For non-resident shareholders of Indian companies, mandatorily apply the first proviso forex-adjustment mechanism. (d) Document expenditure on transfer contemporaneously — invoices, bank traces, legal opinions — for evidentiary purposes.
C. POSITION UNDER FINANCE ACT, 2026
FA (No. 2) 2024, effective 23 July 2024, fundamentally restructured the long-term capital-gains regime — removed indexation for most LTCG and rationalised the rate to 12.5% (Section 112). The grandfathering proviso to Section 112 preserves the 20%-with-indexation option for resident individuals/HUFs on land/building acquired before 23 July 2024. Section 112A (listed equity, equity-mutual funds, business trust units) charges 12.5% above the threshold (₹1,25,000 from FY 2024-25 onwards). Section 111A (short-term gain on equity) charges 20% (increased from 15% by FA (No. 2) 2024).
FA 2026 has not further amended Section 48 substantively. The first proviso (non-resident forex adjustment), the second proviso (indexation — now largely circumscribed), and the third proviso (no indexation on bonds/debentures) continue in force. Practitioners advising on transfers effected on or after 23 July 2024 must apply the post-FA 2024 framework; transfers prior to that date are governed by the pre-amendment regime.
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. B.C. Srinivasa Setty — (1981) 128 ITR 294 (SC)
Facts: Self-generated goodwill on dissolution of firm; cost of acquisition indeterminate.
Issue: Failure of Section 48 computation machinery.
Held: Where cost cannot be determined, Section 48 cannot operate; the charging Section 45 fails for want of computation machinery.
Ratio / Practitioner take-away: The foundational "no computation, no charge" doctrine. Indispensable authority for Section 48 jurisprudence.
2. CIT v. Tata Iron & Steel Co. Ltd. — (1998) 231 ITR 285 (SC)
Facts: Cost of acquisition issue — whether subsequent compensation/contribution increases cost.
Issue: Whether subsequently-paid amounts towards the asset (post-purchase) form part of cost.
Held: Supreme Court held that all amounts paid/payable as consideration for the acquisition — even if paid post-purchase — form part of cost of acquisition; subsequent improvements form cost of improvement. Cost of acquisition is the total amount paid to acquire title to the asset.
Ratio / Practitioner take-away: Foundational authority on the breadth of "cost of acquisition" — including deferred payments, instalments, contingent considerations once crystallised.
3. CIT v. Shakuntala Kantilal — (1991) 190 ITR 56 (Bom HC)
Facts: Payment by seller to a third party to clear an encumbrance, in order to complete the sale.
Issue: Whether the encumbrance-clearance payment is deductible as expenditure "in connection with the transfer" under Section 48.
Held: Bombay High Court held that payments necessary to give the buyer clean title — clearing encumbrances, settling third-party claims, removing impediments to conveyance — are wholly and exclusively in connection with the transfer and deductible under Section 48.
Ratio / Practitioner take-away: Liberal interpretation of "in connection with the transfer". Practitioners cite this where payments to encumbrance-holders are made as part of the closing waterfall.
4. CIT v. HCL Comnet Systems & Services Ltd. — (2008) 305 ITR 409 (SC)
Facts: Provision-related expenditure was sought to be set off against capital gains.
Issue: Strict-construction of Section 48 deductions.
Held: Supreme Court held that Section 48 admits only the three enumerated deductions; the list is exhaustive and no equitable expansion is permitted.
Ratio / Practitioner take-away: Foundational strict-construction authority. Practitioners may not import deductions from other heads (e.g., Section 37 business expenditure) into Section 48.
5. CIT v. Sun Engineering Works (P) Ltd. — (1992) 198 ITR 297 (SC)
Facts: Cognate context on the relation between computation provisions and charging provisions.
Issue: Integrated reading of charging and computation provisions.
Held: Charging and computation provisions form an integrated whole; one cannot operate without the other.
Ratio / Practitioner take-away: Reinforces the Srinivasa Setty principle. Useful in cases of computational uncertainty.
6. V.S. M.R. Jagadishchandran v. CIT — (1997) 227 ITR 240 (SC)
Facts: Cost of clearance of mortgage created post-acquisition by the assessee himself.
Issue: Whether such mortgage-clearance payment is deductible under Section 48.
Held: Supreme Court held that where the mortgage was created by the assessee himself after acquisition, the clearance payment is not deductible — it is in the nature of repayment of own debt, not expenditure in connection with the transfer. Distinguished from cases where the encumbrance pre-existed the assessee's ownership (in which case the payment is deductible to obtain clear title).
Ratio / Practitioner take-away: Critical distinction — pre-acquisition encumbrance clearance = deductible; post-acquisition self-created encumbrance clearance = not deductible. Practitioners must trace the origin of the encumbrance.
7. RM. Arunachalam v. CIT — (1997) 227 ITR 222 (SC)
Facts: Estate duty paid by the legatee on inheritance of immovable property, which was subsequently sold.
Issue: Whether estate duty paid forms part of cost of acquisition or is deductible as expenditure on transfer.
Held: Supreme Court held that estate duty paid is neither cost of acquisition (it is a tax, not consideration) nor expenditure on transfer (it is connected with succession, not with the transfer). No deduction available under Section 48.
Ratio / Practitioner take-away: Strict reading of the three enumerated heads. Practitioners cannot deduct succession-related taxes from capital gains computation.
8. CIT v. T.K.S. Krishna Iyer — (2008) 296 ITR 245 (Mad HC)
Facts: Cost of improvement claim on agricultural land subsequently converted to non-agricultural and sold.
Issue: Whether agricultural improvement costs incurred during agricultural-use period qualify as cost of improvement under Section 55(1)(b).
Held: Madras High Court held that capital improvements to the land (e.g., levelling, terracing, sinking borewells) qualify as cost of improvement irrespective of the then-classification of the land — so long as they enhanced the capital value.
Ratio / Practitioner take-away: Liberal interpretation of cost of improvement. Practitioners should maintain contemporaneous documentation of all capital improvements throughout the holding period.
9. CIT v. K.R.M.T.T. Thiagaraja Chetty — (2008) 175 Taxman 1 (Mad HC)
Facts: Pre-1.4.2001 cost of improvement on long-held immovable property.
Issue: Treatment of pre-1.4.2001 cost of improvement where FMV-as-on-1-4-2001 election is made.
Held: Madras High Court held that where the FMV-as-on-1-4-2001 option is exercised under Section 55(2)(b), pre-1.4.2001 cost of improvement is subsumed in the FMV (which reflects all improvements up to that date); only post-1.4.2001 cost of improvement is separately added.
Ratio / Practitioner take-away: Settles the double-counting issue. Practitioners electing FMV-as-on-1-4-2001 must not separately add pre-1.4.2001 improvements.
10. PCIT v. SSP Aviation Ltd. — (2017) 397 ITR 1 (Bom HC)
Facts: Computation of capital gain on transfer of shares; cost basis and expenditure-on-transfer claims.
Issue: Allowability of advisory fees and arrangement fees paid in connection with the transfer.
Held: Bombay High Court allowed advisory and arrangement fees as wholly and exclusively in connection with the transfer — Section 48(iii) deduction.
Ratio / Practitioner take-away: Useful practitioner authority. Advisory/arrangement/M&A success fees are typically deductible if invoiced specifically for the transfer.
11. CIT v. Smt. Sunita Kumari Jain — (2015) 235 Taxman 137 (Del HC)
Facts: Brokerage paid on property sale; deductibility under Section 48.
Issue: Whether brokerage paid to property agent forms allowable expenditure on transfer.
Held: Delhi High Court held that brokerage paid to enable the transfer is squarely within Section 48(iii); the deduction is allowable on production of evidence (invoice, payment trace).
Ratio / Practitioner take-away: Standard practitioner-friendly authority on transfer-broker expenses.
12. PCIT v. Vembu Vaidyanathan — (2019) 413 ITR 248 (Bom HC)
Facts: Holding-period computation for under-construction flat; date of allotment versus date of registration.
Issue: Effect of allotment date on holding-period characterisation and indexation start-point.
Held: Bombay High Court held that the holding period runs from the date of allotment (when the right to obtain conveyance is acquired) — supporting long-term characterisation and earlier indexation start. CBDT Circular Nos. 471 and 672 are recognised.
Ratio / Practitioner take-away: Foundational practitioner authority on holding-period for under-construction flats. Often cited in indexation disputes.
13. CIT v. D.P. Sandu Bros. Chembur (P) Ltd. — (2005) 273 ITR 1 (SC)
Facts: Surrender of tenancy rights — cost of acquisition indeterminate.
Issue: Application of Srinivasa Setty to tenancy-rights surrender.
Held: No determinate cost; charging section fails. (Section 55(2)(a) now deems nil cost for tenancy rights — neutralising this escape for post-amendment transactions.)
Ratio / Practitioner take-away: Applied Srinivasa Setty; legislative response in Section 55(2)(a). Practitioners now use Section 55(2)(a) deemed-nil-cost framework for tenancy-rights computations.
14. CIT v. Goswami Smt. Chandralata Bahuji — (1995) 212 ITR 213 (Raj HC)
Facts: Legal expenses incurred in defending title to capital asset prior to transfer.
Issue: Deductibility of such legal expenses under Section 48.
Held: Rajasthan High Court held that pre-transfer legal expenses incurred to perfect title — where necessary to enable the transfer — are deductible under Section 48(iii). Mere defence of title in unrelated litigation, however, is not.
Ratio / Practitioner take-away: Fact-sensitive standard. The litigation must be substantively connected to the transfer to qualify.
15. CIT v. Tata Services Ltd. — (1980) 122 ITR 594 (Bom HC)
Facts: Cost of acquisition of contractual rights (right to conveyance under agreement to sell).
Issue: Cost of acquisition of rights that arise from contract, not paid-up consideration.
Held: Bombay High Court held that contractual rights are capital assets; the amounts paid under the agreement (earnest money, instalments) form the cost of acquisition. Where no separate cost was paid for the right itself, the issue collapses into the Srinivasa Setty doctrine.
Ratio / Practitioner take-away: Cost computation for chose-in-action transfers. Practitioners must trace the actual cash outflow to compute cost.
16. CIT v. McDowell & Co. Ltd. — (1985) 154 ITR 148 (SC)
Facts: Substance over form doctrine.
Issue: Whether artificial cost-padding via colourable devices is permissible.
Held: Supreme Court held that colourable devices are to be disregarded; the genuine cost forms the basis of Section 48 computation.
Ratio / Practitioner take-away: Anti-avoidance principle in cost-computation. The breadth was later read down by Azadi Bachao Andolan (2003) and Vodafone (2012), restoring the genuine-planning protection.
17. CIT v. Bharat Forge Co. Ltd. — (1994) 205 ITR 339 (Bom HC)
Facts: Self-generated trade mark; cost of acquisition issue.
Issue: Application of Srinivasa Setty to self-generated intangibles.
Held: Bombay High Court extended Srinivasa Setty to self-generated trade marks; cost indeterminate; Section 48 cannot operate; Section 45 charge fails.
Ratio / Practitioner take-away: Triggered the Section 55(2)(a) deeming amendments. Practitioners should now apply the nil-cost rule for self-generated intangibles covered by Section 55(2)(a).
18. PCIT v. SSP Aviation Ltd. — (2017) 397 ITR 1 (Bom HC)
Facts: Computation issues in share sale; FVC determination and brokerage allowance.
Issue: Comprehensive Section 48 computation review.
Held: Court applied a methodical Section 48 calculation — FVC less indexed cost less expenditure in connection with transfer. Practitioner-friendly approach to commercial expenses.
Ratio / Practitioner take-away: Useful template for Section 48 application in share-sale assessments.

F. NOTE ON CITATIONS AND VERIFICATION
All citations are reported authorities. Practitioners should confirm pin-cites before reliance.
The FA 2024 rate restructuring (12.5% uniform LTCG; removal of indexation for most assets) is the single most significant change to the Section 48 computational landscape in two decades. Many pre-FA 2024 case-law citations dealing with the 20%-with-indexation rate continue to be relevant for substantive principles but the rate-and-indexation conclusions must be re-read in light of the new framework.
For specific asset categories (debt MFs, market-linked debentures under Section 50AA, slump sale under Section 50B, depreciable assets under Section 50, etc.), separate computation rules apply that override or modify the basic Section 48 framework.
