Slump Sale vs Share Sale vs Asset Sale: Legal & Tax Comparison

When a business is on the table, the structure you choose is not a formality. It sets the tax bill, the GST position, the stamp duty exposure, and, critically, who wakes up three years later with a tax department notice about a deal that closed clean. The choice between a slump sale, a share sale, and an asset sale is one of the most consequential decisions in any Indian M&A transaction, yet the frameworks that govern each route sit across four different statutes: the Income Tax Act 1961 (and now the Income Tax Act 2025 effective 01 April 2026), the Companies Act 2013, the Central Goods and Services Tax Act 2017, and the Foreign Exchange Management Act 1999. Getting comfortable in all four simultaneously is not the norm. This article maps every dimension you need, with specific section references, current tax rates for FY 2026-27, and a decision framework you can take to your board.

Which is better: slump sale, share sale, or asset sale?

The answer depends on three variables: who carries the contingent liability risk, which party needs a tax step-up in asset values, and whether GST going-concern treatment is achievable. Slump sale is typically the seller’s preferred structure because Section 50B produces a single undertaking-level capital gain taxed at 12.5% LTCG (if held over 36 months), avoiding the fragmented and often higher tax burden of an asset-by-asset sale. Share sale is operationally fastest and imposes the lowest stamp duty, but transfers all historical liabilities to the buyer. Asset sale gives the buyer clean title and a tax depreciation step-up but creates the highest aggregate GST and compliance cost. No structure is universally superior; the right choice is transaction-specific.

What is a slump sale and how does Section 50B work?

A slump sale is the transfer of one or more undertakings for a lump-sum consideration, without values being assigned to individual assets and liabilities in the transfer. The definition is in Section 2(42C) of the Income Tax Act 1961. The Finance Act 2021 broadened the scope: a slump sale can now be effected “by any means,” covering not just cash sales but also share-swap transactions, barter, and exchange. Post-amendment, there is no avenue to structure a business transfer as a slump exchange and escape capital gains tax.

The tax computation mechanism is in Section 50B. The key elements are:

• The entire undertaking is treated as a single capital asset, not as a collection of individual assets
• The cost of acquisition is the net worth of the undertaking: aggregate of written-down values of depreciable assets plus book values of other assets, reduced by the value of liabilities, as appearing in the seller’s books
• The full value of consideration is the higher of the actual transaction price or the fair market value computed under Rule 11UAE of the Income Tax Rules 1962
• No indexation benefit is available, regardless of the holding period
• No separate depreciation recapture under Section 50 applies; all gains are subsumed within Section 50B

The holding period test determines LTCG or STCG character:

Holding period of the undertaking	Character	Tax rate (FY 2026-27)
More than 36 months	Long-term capital gain	12.5% (no indexation)
36 months or less	Short-term capital gain	Slab rate for individuals; 25.17% for domestic companies (base 22% + surcharge + cess)

The 36-month threshold for slump sales is deliberately longer than the 24-month rule for unlisted shares and the 12-month rule for listed shares. A manufacturing unit set up and divested within three years will produce STCG, not LTCG, regardless of the lump-sum nature of the transfer.

What is the Rule 11UAE dual FMV test?

CBDT notified Rule 11UAE via Notification No. 68/2021 dated 24 May 2021. The rule introduces a mandatory dual FMV test to determine the full value of consideration for Section 50B. Two values are computed:

FMV1 is an asset-side valuation. It adds up the fair market values of the undertaking’s assets: book value for most assets, registered valuer reports for jewellery and art, stamp duty value for immovable property, and Rule 11UA-based valuations for shares in other companies.

FMV2 is a consideration-side valuation. It captures the actual consideration received, including the fair value of any non-cash consideration such as shares received in a share swap.

The higher of FMV1 and FMV2 is treated as the full value of consideration. This means the agreed transaction price is not the final figure for income tax computation. If the underlying asset base (FMV1) is higher than what the buyer paid, the seller is taxed on FMV1. The rule was specifically introduced to prevent sellers from understating consideration to reduce capital gains.

Practical consequence for deal structuring: in any slump sale where the seller holds significant immovable property (land, buildings at stamp duty value) or unquoted investments, FMV1 is likely to exceed the negotiated deal price for at least some asset categories. The tax opinion must map both FMV1 and FMV2 before the price is fixed in the term sheet.

What is Form 3CEA and when is it mandatory?

Every seller in a slump sale must obtain a report from a Chartered Accountant in Form 3CEA, certifying that the net worth has been correctly computed. Under Rule 6H read with Section 50B(3), this report must be filed with the income tax return for the assessment year in which the slump sale occurred. Failing to file Form 3CEA, or filing one with an incorrect net-worth computation, exposes the seller to reassessment, interest, and penalty under Section 271(1)(c). CBDT has increased audit scrutiny of Form 3CEA filings since 2024, particularly where the net worth figure produces a low or nil capital gain.

How is a share sale taxed in India?

In a share sale, the buyer acquires the equity shares of the target company from its existing shareholders. The target company itself, including all its assets, liabilities, contracts, licences, and employees, remains intact. The corporate entity does not change; only its shareholders do.

The seller’s capital gain is the difference between the sale price per share and the cost of acquisition per share.

For unlisted company shares, the applicable rules are:

Holding period	Character	Tax rate (FY 2026-27)
More than 24 months	Long-term (Section 112)	12.5% without indexation
24 months or less	Short-term	Applicable income tax slab rate

The Finance (No. 2) Act 2024 reduced the LTCG rate on unlisted shares from 20% with indexation to 12.5% without indexation, effective 23 July 2024. This rate applies unchanged in FY 2026-27 (AY 2027-28). Treelife’s detailed guide on tax on sale of unlisted shares covers the full computation including Section 50CA (FMV floor for sellers), Section 56(2)(x) (buyer’s exposure on below-FMV acquisitions), and NRI taxation under Section 195.

FMV floor under Section 50CA: if a seller transfers unlisted shares below their fair market value as computed under Rule 11UAA, the FMV is deemed to be the full value of consideration. The seller pays capital gains tax on the FMV, not on the actual price received. This is the share-sale equivalent of Rule 11UAE for slump sales, and it operates identically.

Carry-forward of losses in the target: one significant buyer-side advantage of a share sale is that the target company’s accumulated business losses and unabsorbed depreciation remain in the company and can be used post-acquisition, subject to the change-in-shareholding restrictions under Section 79 of the Income Tax Act 1961. A 51% or more change in shareholding in a year can extinguish carry-forward losses in a closely held company. Treelife’s analysis on Section 79 covers this in detail.

Securities Transaction Tax (STT): STT applies only on transfers of listed shares through recognised stock exchanges. Transfers of unlisted shares, whether private limited or public unlisted, do not attract STT. There is no STT on secondary transfers of unlisted company equity.

How is an asset sale taxed?

An asset sale, sometimes called an itemised sale, transfers specific assets and specified liabilities. The seller assigns individual values to each asset, and a separate instrument is executed for each transfer. The seller retains the corporate entity and any assets not included in the transaction.

The tax treatment is fragmented:

Depreciable assets (plant, machinery, vehicles, computers): gains on depreciable assets in a block are taxed as short-term capital gains under Section 50, regardless of how long the asset has been held. This is the most significant tax disadvantage of an asset sale relative to a slump sale. In a slump sale, those same depreciable assets are subsumed into the undertaking and can produce LTCG at 12.5% if the undertaking is held over 36 months.

Other capital assets (land, buildings held as investment, goodwill, intellectual property): gains are classified as STCG or LTCG based on the individual holding period, at the standard rates.

Inventory and receivables: gains on stock-in-trade and trade receivables transferred are treated as business income, not capital gains, and taxed at the seller’s slab or corporate tax rate.

The aggregate tax burden in an asset sale is therefore almost always higher than in a slump sale for the same underlying business value, because depreciable asset gains are always short-term and inventory gains are ordinary income.

Buyer-side advantage: the buyer acquires assets at the actual purchase price, not at the seller’s written-down values. This higher cost base immediately starts generating enhanced depreciation claims on the acquired assets. For a buyer acquiring a business with significant fixed assets, this depreciation shield is a tangible post-acquisition benefit that a share sale does not provide.

How goodwill is treated across all three structures

Goodwill is where buyers most consistently overestimate their post-acquisition tax benefit, and sellers most consistently misread their capital gains exposure. The position differs materially across structures.

In a slump sale, self-generated goodwill (built by the seller organically, not purchased from a prior owner) is part of the transferred undertaking. For Section 50B net worth computation, its book value is nil, because self-generated goodwill has no recorded cost. However, FMV1 under Rule 11UAE captures the economic value of goodwill within the overall business enterprise valuation, which means the FMV1 figure is likely to exceed the net worth figure wherever the business has significant brand value, customer relationships, or market position. The seller is taxed on that FMV1 surplus. The buyer, once it receives the undertaking, cannot claim depreciation on the goodwill embedded in the slump sale price. Following the Finance Act 2021 amendment to Section 32 of the Income Tax Act 1961, goodwill is explicitly excluded from the list of depreciable intangible assets. This applies regardless of whether the goodwill was acquired through a slump sale, asset purchase, or amalgamation.

In a share sale, goodwill does not appear in the target company’s own books unless the target itself made an acquisition in the past. The acquiring shareholder records goodwill at the consolidated level under Ind AS 103 (Business Combinations) as the excess of the purchase consideration over the fair value of the net identifiable assets acquired. This consolidated goodwill is not tax-deductible and not amortisable for income tax purposes. The Supreme Court’s ruling in Smifs Securities Ltd. v. Commissioner of Income Tax, which allowed depreciation on purchased goodwill, was neutralised by the Finance Act 2021 amendment removing goodwill from Section 32. A buyer paying a significant premium over book value in a share sale derives no depreciation benefit from that premium.

In an asset sale, purchased goodwill can be explicitly identified and valued as an intangible asset in the asset purchase agreement. But the Finance Act 2021 amendment applies equally here: goodwill, even if purchased separately in an itemised asset acquisition, is not eligible for depreciation under Section 32 from FY 2021-22 onwards. The step-up benefit in an asset sale is therefore real for plant, machinery, and other eligible depreciable assets, but it does not extend to the goodwill component of the purchase price.

Practical implication: buyers who model their post-acquisition tax shield must exclude goodwill from the depreciation calculation regardless of structure. Where goodwill represents a significant proportion of the total consideration, the asset sale’s depreciation step-up advantage over a share sale is smaller than it initially appears.

GST treatment: which structure is exempt and which is not?

Share sale: shares are securities, not goods or services, and their transfer is not a supply under the Central Goods and Services Tax Act 2017. A share sale is GST-neutral for both parties. No GST applies.

Slump sale as a going concern: the GST Council and CBIC have confirmed that a transfer of business as a going concern is not a supply of goods or services. Entry 2 of Notification No. 12/2017-Central Tax (Rate) exempts such transfers. For this exemption to apply, the transfer must satisfy all of the following conditions:

• All assets necessary for the business to continue operating are transferred
• Associated liabilities are also transferred
• Employees migrate to the buyer and the business continues post-transfer
• The buyer actually carries on the business activity after taking over
• Input tax credit balances are transferred to the buyer under Form GST ITC-02

Critically, CBIC does not look only at the agreement. GST officers examining going-concern claims in 2025 and 2026 have demanded post-closing evidence: employee transfer letters, first post-closing invoice raised by the buyer under the transferred business, supplier intimation letters, and ITC-02 filing confirmation. A slump sale agreement that says “going concern” but lacks this trail is vulnerable to the exemption being denied.

Asset sale: each asset transferred is a separate supply. Goods attract GST at applicable rates (5%, 12%, 18%, or 28% depending on the asset category). Services (such as contracts being novated) attract GST on the service component. The going-concern exemption is not available for asset sales. This can add a material GST cost to the transaction, which is recoverable as input tax credit by the buyer only if it is GST-registered and uses the assets in a taxable business.

Illustrated comparison: a manufacturing unit with equipment worth ₹10 crores, inventory worth ₹3 crores, and land worth ₹5 crores transferred as an asset sale would attract approximately ₹1.8 crores in GST on equipment and inventory at 18%. The same transfer as a qualifying going-concern slump sale would attract nil GST.

Stamp duty: which structure costs more?

Stamp duty in India is levied under the Indian Stamp Act 1899 and state-level stamp schedules. The rates and the definition of the chargeable instrument vary by state.

Share sale: stamp duty on share transfer instruments is the lowest of the three structures. For shares in dematerialised form held in a depository, the transfer attracts stamp duty at 0.015% on the consideration under the Securities (Contracts) Regulation Act framework. For physical share certificates in an unlisted company, rates are set by state law but are generally a small fraction of the asset transfer alternative. From a stamp duty standpoint, the share sale wins in almost every Indian state.

Slump sale: a slump sale agreement is a conveyance of a business undertaking. States treat this as a conveyance of the underlying assets, and the stamp duty is generally computed on the higher of the consideration or the market value of the property transferred. State stamp authorities in Maharashtra, Karnataka, and several other states have a practice of independently assessing the market value of the assets conveyed in a slump sale, and issuing demand notices for differential duty years after the transaction. The lump-sum consideration gives the authority an opening to argue that individual assets, particularly immovable property, should be stamped at their independent market value rather than as an embedded component of the lump sum. Assigning stamp values for individual immovable properties in the sale agreement (permissible under Section 2(42C) Explanation 2, which clarifies that such assignment for stamp purposes does not disqualify the transaction as a slump sale) is often the right approach.

Asset sale: each instrument of transfer is separately stampable. A conveyance for immovable property, an assignment of intellectual property, bills of sale for movables, and assignments of contracts each carry their own stamp duty. The aggregate across all instruments can easily exceed the stamp cost of a single slump-sale conveyance.

Structure	Stamp duty character	Typical outcome
Share sale	Flat rate on consideration (dematerialised: 0.015%)	Lowest
Slump sale	Conveyance duty on lump sum; state market-value scrutiny risk	Medium; risk of retrospective demands
Asset sale	Separate duty per instrument; duty on immovable property at state rates	Highest in aggregate

Liability transfer: who carries the risk?

This is the dimension where buyers have the strongest preference, and where structuring produces the clearest tradeoffs.

Share sale: all liabilities, known and unknown, historical and contingent, remain inside the target company. The buyer acquires a company with its full history: pending income tax assessments, GST notices, employee provident fund arrears, product liability claims, environmental obligations, and any undisclosed creditor claims. A share sale requires the deepest due diligence precisely because there is no mechanism to exclude a liability that has not yet been identified.

The standard risk-management tools in a share sale are: comprehensive representations and warranties from the seller covering all material liabilities, an indemnity basket covering identified and unknown claims up to specified caps, and an escrow holdback of a portion of the consideration for a defined tail period. Representations and Warranties (R&W) insurance, available in the Indian market through a small number of specialist insurers, can take some of the indemnity risk off the seller’s balance sheet.

Slump sale: liabilities associated with the undertaking transfer with it. The seller and buyer must identify and agree which liabilities are “undertaking liabilities” (and transfer) versus “corporate liabilities” (and stay with the seller entity). Specific carve-outs for pre-closing tax liabilities, pre-closing litigation, and historical regulatory non-compliance are negotiated and documented in the business transfer agreement. Indemnity clauses cover identified pre-closing exposures for an agreed period.

Asset sale: the buyer has maximum control. Only the explicitly listed liabilities are assumed. Unknown and contingent liabilities remain with the seller’s corporate entity. This makes the asset sale the cleanest structure from a buyer’s liability perspective, at the cost of more complex documentation and slower execution.

Which liabilities can be carved out of a slump sale without killing the deal?

This is the question every buyer’s counsel raises and every article on slump sales avoids answering precisely. Case law has settled the boundary.

The Supreme Court in Commissioner of Income Tax (Central), Calcutta v. Mugneeram Bangur held that a slump sale remains valid even where specific, limited pre-closing liabilities are excluded, provided the transferred undertaking still functions as a going concern. The categories that have been accepted as valid carve-outs include pending income tax assessments and demands relating to pre-closing periods, specific litigation where the liability is the seller’s personally, and contingent obligations that are clearly identifiable and not core to business operations.

By contrast, the Income Tax Appellate Tribunal in Kampli Co-operative Sugar Factory Ltd. v. Joint Commissioner of Income Tax held that excluding all liabilities of the undertaking converts the transfer into an itemised asset sale, disqualifying it from Section 50B treatment entirely.

The practical boundary: you can carve out identified, named pre-closing disputes by placing them on an indemnity schedule covered by the seller. You cannot exclude the ongoing trade creditors, employee liabilities, lease obligations, and working capital payables of the business without breaking the going-concern character of the undertaking.

The Section 170 succession risk that buyers miss

The Finance Act 2021 amendment to Section 170A of the Income Tax Act 1961, read with the Mumbai ITAT ruling in M/s. Archroma India Pvt. Ltd. v. ITO (June 2020), confirmed that a slump sale constitutes succession of business. This has a consequence that no standard slump sale due diligence checklist captures: the buyer becomes a successor to the business for pending tax assessments and demands under Section 170, not just a contractual indemnity holder.

If the income tax officer was in the process of framing an assessment against the seller’s undertaking at the time of the slump sale, Section 170 empowers the officer to proceed against the buyer as the successor, without requiring the officer to first exhaust remedies against the seller. The buyer’s contractual indemnity from the seller is a remedy between private parties; it does not override the tax department’s right to proceed against the successor.

This risk is most acute where the undertaking has pending transfer pricing disputes, GST audits, or high-value TDS demand proceedings. In such cases, the buyer should: (a) obtain a tax due diligence certificate covering all open assessments up to the date of transfer, (b) structure a specific escrow holdback sized to cover the open demand plus interest and penalty, and (c) negotiate a seller indemnity that survives for the full period of the assessment proceedings, not just a fixed post-closing tail.

Companies Act 2013 and SEBI approvals: what each structure needs

Slump sale approval requirements

Section 180(1)(a) of the Companies Act 2013 requires a special resolution (75% majority) for any sale, lease, or disposal of “the whole or substantially the whole” of an undertaking. The Act defines “substantially the whole” through a two-limb test: an undertaking in which investment exceeds 20% of the company’s net worth, or an undertaking generating more than 20% of the company’s total income, as per the latest audited balance sheet.

Points to note:

• Section 180 applies to public companies. Private limited companies are exempt from Section 180 by virtue of MCA Notification No. F.No. 1/1/2014-CL.V dated 05 June 2015.
• If the thresholds are not met, Section 180 is not triggered and board-level approval suffices.
• A slump sale can also be executed through a Scheme of Arrangement under Sections 230-232, which requires NCLT approval along with member and creditor approval (75% in value).

For listed companies, SEBI (Listing Obligations and Disclosure Requirements) Regulations 2015 Regulation 37A adds a further requirement: shareholder approval by special resolution plus consent of the “majority of minority shareholders” (minority being defined as shareholders other than the controlling entity) is required for any sale or disposal of an undertaking by a listed entity. This majority-of-minority vote is independent of the special resolution threshold and creates a veto right for non-controlling public shareholders. This is a significant addition that can affect deal timelines for listed company divestitures.

Share sale approval requirements

A share sale by shareholders requires no Company Law approval at the company level, since the company itself is not a party to the transaction. The shareholders enter into a share purchase agreement directly.

Where the target is a private limited company, the Articles of Association will typically contain pre-emption rights (right of first refusal among existing shareholders) and right of first offer provisions, as well as consent rights under any Shareholders’ Agreement. These contractual constraints must be mapped before the term sheet is signed.

For cross-border share sales involving a non-resident buyer or seller, FEMA and RBI compliance applies (discussed below).

Asset sale approval requirements

An asset sale involving specific categories of assets has its own requirements:

• Transfer of immovable property requires registration of the conveyance deed under the Registration Act 1908
• Assignment of contracts generally requires written consent of the counterparty
• Transfer of licences and regulatory approvals is subject to the terms of each licence; many sector-specific licences are non-transferable and must be freshly obtained by the buyer
• Intellectual property assignments may require recordal with the relevant authority (Trademarks Registry, Patent Office)

Board approval for asset sales is generally sufficient where the sale value is within the delegated financial authority of the board. Where it is not, shareholder approval may be needed depending on the company’s Articles.

Section 281 No Objection Certificate in asset sales. Section 281 of the Income Tax Act 1961 renders void, against the income tax authorities, any transfer of an asset by a taxpayer where a tax liability exists or is likely to arise, unless the income tax authority grants prior permission. In a high-value asset sale, the buyer should obtain a No Objection Certificate (NOC) from the income tax officer of the seller’s jurisdiction before the transaction closes. Without the NOC, assets the buyer has paid for can be attached by the income tax department to recover the seller’s pre-closing tax dues, even though the buyer has already paid the seller. The seller’s contractual indemnity provides no protection against a tax department attachment of assets the buyer legally owns. This requirement is routinely overlooked in asset transactions and is absent from most standard asset purchase agreement checklists.

Section 194-Q TDS in asset sales. Section 194-Q of the Income Tax Act 1961 requires a buyer whose preceding-year gross receipts exceed ₹10 crores to deduct TDS at 0.1% on payments for goods exceeding ₹50 lakhs in a financial year. An asset sale that includes inventory, raw materials, or finished goods will almost certainly cross this threshold. The buyer must deduct TDS before releasing payment for the goods component; non-deduction makes the buyer an assessee-in-default under Section 201, which disallows the payment as an expense deduction and attracts interest under Section 201(1A). In a slump sale, the majority view holds that the lump-sum consideration for a going-concern transfer is not a “purchase of goods” for Section 194-Q purposes, and TDS does not apply. A formal tax opinion is still recommended before closing.

FEMA compliance: what changes when a non-resident is involved

Share sale involving a non-resident buyer acquiring shares from a resident: The transfer price must be at least equal to the fair value of the shares as determined by an internationally recognised valuation methodology (typically DCF or NAV, certified by a SEBI-registered Category I Merchant Banker or a Chartered Accountant using internationally accepted methods). The resident seller cannot transfer below fair value to a non-resident. Form FC-TRS must be filed with the Authorised Dealer Bank within 60 days of receipt of consideration. The Authorised Dealer Bank processes the filing and reports to RBI. Missing the 60-day deadline attracts compounding proceedings under FEMA, with penalties that can reach three times the transaction amount.

Share sale involving a non-resident seller exiting to a resident buyer: The transfer price must not exceed the fair value. The non-resident cannot extract more than arm’s-length value. The resident buyer must deduct TDS under Section 195 before remitting the sale consideration. Form 15CA and Form 15CB (CA-certified) are required before remittance. The resident buyer files Form FC-TRS within 60 days of payment.

Slump sale to a non-resident buyer: FEMA does not have a specific provision for slump sales. The transaction is analysed as the non-resident making an investment in India by acquiring business assets. If the target is a company and the buyer acquires the undertaking (not shares), the investment is treated as an FDI flow in the applicable sector. Sector-specific FDI caps and conditionalities apply. FEMA compliance must be structured with the RBI’s Authorised Dealer Bank before closing.

Asset sale to a non-resident buyer: same analysis as slump sale. Each asset category is examined against sector-specific FDI rules. Immovable property transfers are subject to FEMA restrictions on non-resident acquisition of Indian property.

A worked numeric comparison

Consider a manufacturing company with the following balance sheet for its Widget division:

• Gross block of depreciable assets: ₹15 crores (WDV ₹8 crores)
• Land (non-depreciable): ₹10 crores (book value ₹3 crores, stamp duty value ₹9 crores)
• Inventory: ₹4 crores
• Receivables: ₹2 crores
• Liabilities of the division: ₹6 crores
• Net worth of the division: ₹21 crores (sum of WDV + book values minus liabilities)
• Agreed enterprise value: ₹30 crores

The company has held the Widget division for more than 36 months.

Slump sale outcome (assuming FMV1 = ₹32 crores, FMV2 = ₹30 crores): Full value of consideration = ₹32 crores (higher of FMV1 and FMV2 under Rule 11UAE) Capital gain = ₹32 crores minus ₹21 crores = ₹11 crores Tax at LTCG rate (company): approximately ₹1.38 crores (12.5% plus surcharge and cess) GST: Nil (going-concern exemption, if conditions met)

Asset sale outcome:

• Gain on depreciable assets (STCG under Section 50): ₹7 crores gain (₹15 crores gross block minus ₹8 crores WDV)
• Tax on depreciable asset gain at corporate STCG rate (25.17%): approximately ₹1.76 crores
• Gain on land (LTCG, held over 24 months): ₹7 crores (₹10 crores minus ₹3 crores book)
• Tax on land gain at 12.5% LTCG: approximately ₹0.88 crores
• Inventory gain treated as business income at 25.17%: approximately ₹1.01 crores
• GST on equipment and inventory at 18%: approximately ₹2.16 crores (recoverable by buyer as ITC if eligible)
• Total tax (excluding stamp duty): approximately ₹3.65 crores on the seller side
• Stamp duty: multiple instruments, state-specific

Share sale outcome (selling shares representing the entire company, which holds only the Widget division): Assumes the company’s equity is entirely attributable to the Widget division.

• Shares held over 24 months: LTCG under Section 112
• Capital gain = ₹30 crores consideration minus cost of acquisition of shares (varies by how the company was capitalised)
• Tax rate: 12.5% LTCG (plus surcharge and cess)
• GST: Nil
• Buyer does not get asset step-up or depreciation benefit

The numeric comparison demonstrates the core pattern: slump sale produces one capital gain at LTCG rates, avoiding the STCG trap on depreciable assets that makes an asset sale expensive.

What has changed in 2025 and 2026 that affects your decision?

Four developments since 2024 have shifted the risk calculus:

The Income Tax Act 2025 (effective 01 April 2026) consolidates and renumbers the Income Tax Act 1961. The substantive provisions of Section 50B, Rule 11UAE, and Form 3CEA are retained, but section numbers in ITR filings for FY 2026-27 will reference the new Act structure. Tax opinions should reflect this transition.

CBDT scrutiny of Form 3CEA filings has increased materially. Transactions where the net worth computation produces a low or nil capital gain are being selected for scrutiny. Sellers must confirm the CA certifying Form 3CEA has access to the full books of the division, not just a summary extract, and that the WDV of depreciable assets is taken from the depreciation schedule, not estimated.

CBIC going-concern challenge frequency is higher than at any point in the GST regime’s history. Post-closing documentation of employee migration, ITC-02 filing, and continued business activity under the buyer’s GST registration is being demanded. The going-concern exemption is no longer self-applying; it must be earned with contemporaneous evidence.

SEBI LODR Regulation 37A, introduced via amendment, creates the majority-of-minority approval requirement for listed company slump sales. Any promoter-group entity that holds more than 50% but less than 75% of a listed company cannot unilaterally pass a special resolution for a slump sale; it needs the affirmative vote of a majority of the remaining public shareholders. This has changed timelines and negotiation dynamics for listed company divestments.

Slump sale vs demerger: the fourth structure to consider

Every operator who reaches the slump sale vs share sale vs asset sale question will eventually encounter a fourth option: the demerger. A demerger is the transfer, pursuant to a Scheme of Arrangement under Sections 230-232 of the Companies Act 2013, of one or more undertakings from the demerged company to a resulting company. Shareholders of the demerged company receive shares in the resulting company proportionate to their existing holding.

The choice between a slump sale and a demerger turns on two questions: does the seller want cash, or does the seller want the business separated into a standalone entity? And does the tax position of the seller company make the 12.5% slump sale LTCG acceptable, or is a tax-neutral transfer necessary?

Parameter	Slump sale	Qualifying demerger (Section 2(19AA))
Capital gains at company level	Taxable at 12.5% LTCG (if held over 36 months)	Exempt under Section 47(vib) if resulting company is Indian
Consideration form	Cash, shares, or any means	Only shares in the resulting company; no cash permitted
Shareholders’ position	No direct tax event for shareholders	No capital gains tax on receipt of resulting company shares
Carry-forward losses	Do not transfer to buyer	Transfer to resulting company for the transferred undertaking (Section 72A(4))
Regulatory approval	Board and shareholder resolution; NCLT not required	NCLT approval mandatory under Sections 230-232
Timeline	6 to 16 weeks	4 to 9 months
GST	Nil if going concern	Not applicable (asset transfer by operation of law)
Use case	Sell for cash; exit the division entirely	Separate for standalone entity, separate funding, or eventual listing

The demerger’s principal advantage is capital-gains neutrality at both the company level and the shareholder level. A seller company sitting on a low-cost-base undertaking (old factory land, legacy IP, or a business built from near-zero capital) would face a large 12.5% LTCG bill in a slump sale. A qualifying demerger eliminates that charge entirely, subject to the NCLT process and the share-only consideration constraint.

The carry-forward of losses is also structurally superior in a demerger. Under Section 72A(4), the accumulated losses and unabsorbed depreciation directly relatable to the transferred undertaking move to the resulting company. In a slump sale, no losses transfer to the buyer; they stay with the seller entity. For a company separating a loss-making division to give it a fresh start under new ownership, a demerger preserves those losses in the new entity, whereas a slump sale extinguishes them from the buyer’s perspective.

The constraint is that demergers cannot be used for cash exits. If the seller needs liquidity, the demerger route is not available unless the consideration shares in the resulting entity are subsequently sold by the seller’s shareholders on the market or in a secondary transaction. For most M&A transactions where an acquirer is paying consideration, slump sale or share sale will be the operative choice. Demerger becomes relevant when the objective is to separate rather than to sell.

MAT exposure on slump sale gains

If the selling entity is a domestic company subject to Minimum Alternate Tax (MAT) under Section 115JB of the Income Tax Act 1961, the capital gain from the slump sale forms part of book profit for MAT computation. The MAT rate for domestic companies is 15% of book profit (after the Budget 2026 reduction from the prior rate). Where the regular capital gains tax at 12.5% on the net worth-based gain is lower than the MAT liability on the book profit, the company will pay MAT instead. This creates the counterintuitive scenario where a seller company benefits from LTCG treatment in theory but pays a higher effective rate in practice because book profit exceeds the taxable capital gain.

The MAT exposure is particularly relevant where: (a) the slump sale is structured through an NCLT scheme and the book profit includes the full surplus over book value, (b) the seller entity has low net worth (making the Section 50B gain small) but a high market-value surplus captured in book profit, or (c) the company’s accumulated MAT credit balance is insufficient to offset the incremental MAT charge.

Companies incorporated in the International Financial Services Centre (IFSC) at GIFT City are eligible for a reduced MAT rate of 9% under Section 115JB, as confirmed by Budget 2026 amendments. Sellers with GIFT City holding structures should model both the regular capital gains and the MAT position before finalising the deal structure.

Is a CCI filing required, and does your structure choice matter?

The Competition Commission of India (CCI) Combination Regulations require a mandatory pre-closing notification when prescribed thresholds are met. Most startup and mid-market M&A transactions fall below these thresholds, but the structure choice can affect whether the thresholds are triggered.

The standard asset and turnover thresholds for CCI mandatory filing (for parties in India, individually):

• Acquirer + target combined assets in India exceed ₹2,500 crores, or combined turnover in India exceeds ₹7,500 crores
• Or, for globally active parties, combined global assets exceed USD 1 billion with at least ₹1,000 crores in Indian assets, or combined global turnover exceeds USD 3 billion with at least ₹3,000 crores in Indian turnover

The deal value threshold (DVT), introduced by the Competition Amendment Act 2023 and effective from the CCI Combinations Regulations 2024, adds a separate trigger: where the total value of the transaction globally exceeds ₹2,000 crores and the target has substantial business operations in India. This threshold is most relevant for high-value technology and platform acquisitions.

Where structure matters: a slump sale or asset sale of a specific division of a larger company may be scoped to exclude assets and turnover not included in the transferred undertaking. If the transferred undertaking alone falls below the threshold, no CCI filing is required, even if the parent company (which would be the target in a full share sale) clearly exceeds the thresholds. Acquirers who want to avoid the CCI notification process, and the associated timeline and disclosure burden, sometimes prefer a slump sale of a defined business unit over a share sale of the parent entity, where the parent’s aggregate financials would trigger the filing obligation.

CCI pre-filing consultation is available informally before a formal notification is submitted. Where threshold applicability is in doubt, engaging CCI early avoids the risk of a post-closing notification requirement with a penalty for late filing.

Common structuring mistakes that generate notices and disputes

Assigning individual values to assets in the slump sale agreement. Doing this for reasons other than stamp duty calculation disqualifies the transaction as a slump sale and triggers Section 50 on depreciable assets. Each asset-level value in the agreement creates a potential basis for the tax officer to argue this is an itemised sale, not a slump sale.

Missing the Form 3CEA filing. This is a mandatory compliance requirement under Section 50B(3), not optional. Sellers who file their ITR without the Form 3CEA attached face automatic disallowance of slump sale treatment.

Assuming the going-concern GST exemption applies without documentation. The exemption is conditional. A slump sale agreement that transfers all assets and liabilities on paper but where employees were terminated before closing, or where the buyer has not actually continued the business, will lose the exemption in a GST audit.

Not obtaining a Rule 11UA valuation in a share sale. Sellers transferring unlisted shares without a fresh valuation report (dated within 180 days) risk Section 50CA reassessment if the officer independently determines the FMV was higher than the sale price.

Section 79 carry-forward loss extinction in share sale. Buyers acquiring more than 51% of a closely held company’s shares in a year often do not model the loss of the target’s accumulated carry-forward losses under Section 79. Where those losses are material, this should be negotiated into the purchase price.

FC-TRS filing deadline missed in a cross-border share transaction. The 60-day deadline from date of receipt or payment of consideration runs strictly. Missing it requires compounding with the RBI, which is a time-consuming process and imposes costs.

Not getting a majority-of-minority vote for listed company slump sale. Post-SEBI LODR Regulation 37A, a listed company completing a slump sale without this vote is exposed to regulatory action by SEBI and potential challenge by minority shareholders.

Modelling a goodwill depreciation benefit that no longer exists. Post-Finance Act 2021, goodwill is excluded from Section 32 of the Income Tax Act 1961. Buyers in any structure, slump sale, asset purchase, or share acquisition, who build in a depreciation tax shield on the goodwill component of the purchase price are working from a pre-2021 framework that has been legislated away. The error often surfaces only when the first-year depreciation claim is disallowed in scrutiny assessment.

Skipping the Section 281 NOC in an asset sale. Asset buyers who do not obtain a No Objection Certificate from the income tax officer of the seller’s jurisdiction before closing accept the risk that assets they have paid for can be attached by the tax department for the seller’s pre-closing dues. The seller’s indemnity is useless against a statutory attachment. The NOC application is straightforward and adds at most two to three weeks to the timeline; skipping it to save time is a disproportionate risk on high-value asset transactions.

Decision framework: which structure should you choose?

Choose a slump sale when:

• The seller is transferring an entire, operationally complete division or undertaking
• The undertaking has been held for over 36 months (securing LTCG treatment)
• The seller entity is a company or firm (not an individual asset-holder)
• The undertaking has material depreciable assets that would attract STCG in an asset sale
• The going-concern GST exemption is achievable and can be documented post-closing
• The buyer is not critically dependent on a post-acquisition depreciation step-up

Choose a share sale when:

• Operational continuity is non-negotiable (contracts, licences, and relationships cannot survive a business transfer)
• The buyer needs to close quickly and cannot absorb the timeline of an asset transfer or going-concern documentation exercise
• Stamp duty minimisation is a priority and shares are dematerialised
• The target has valuable carry-forward losses that the buyer wants to preserve (subject to Section 79 analysis)
• No non-resident buyer is involved (or FEMA pricing compliance has been separately modelled)

Choose an asset sale when:

• The buyer wants clean, selected assets and must exclude unknown or contingent liabilities
• The buyer needs a tax step-up on acquired fixed assets for post-acquisition depreciation benefit
• The seller wants to retain the corporate entity and other business lines
• The transaction involves cherry-picked assets from a larger business that cannot be structured as a going concern
• GST cost is either manageable or recoverable by the buyer as input tax credit

Priority	Preferred structure
Seller’s tax efficiency on depreciable assets	Slump sale
Lowest GST cost	Slump sale or share sale
Lowest stamp duty	Share sale
Buyer: no liability inheritance	Asset sale
Buyer: depreciation step-up on fixed assets	Asset sale (note: goodwill not depreciable under any structure post-Finance Act 2021)
Operational continuity (licences, contracts)	Share sale
Speed of execution	Share sale
Seller wants to retain the corporate entity	Asset sale
Carry-forward losses preserved in target	Share sale (Section 79 analysis required)
Seller wants tax-neutral separation (low cost-base undertaking)	Qualifying demerger under Section 2(19AA)
Carry-forward losses must transfer to the acquiring entity	Qualifying demerger (Section 72A(4)); losses do not transfer in slump sale or asset sale
Stay below CCI filing threshold on a divisional carve-out	Slump sale or asset sale of the undertaking (assessed on divisional financials, not parent)
Seller entity subject to MAT at 15%+ on book profit	Run MAT vs LTCG comparison before choosing slump sale; model demerger if gain is large

Treelife practitioner note

In the M&A structuring mandates we have run at Treelife, the recurring blind spot is not the headline tax rate. Clients know that LTCG is 12.5%. What they miss, consistently, is the interaction between Rule 11UAE’s FMV1 computation and the stamp duty value of immovable property sitting inside the undertaking. In more than one slump sale we have structured, the FMV1 computed under Rule 11UAE was materially higher than the agreed enterprise value, because the stamp duty value of the land was two to three times its book value. The seller ended up paying tax on a notional gain that did not reflect actual cash received.

The fix is to work out FMV1 explicitly before the LOI, map the stamp duty value of each piece of immovable property, and either adjust the enterprise value upward (if the seller will not accept the notional gain) or restructure the deal to hive out the immovable property separately through a different mechanism before the slump sale. Both paths are available; neither is visible unless the FMV1 computation is run early.

The second pattern we see is on the SEBI LODR majority-of-minority vote for listed company slump sales. Promoters with 55-60% stakes often discover that the minority shareholders hold an effective veto over the divestment. We have seen transactions collapse at the special resolution stage because public shareholders were not brought into the deal narrative early enough. The structural issue is that Regulation 37A requires minority approval, but there is no obligation to consult the minority before announcing the transaction. A promoter who announces the divestment and then seeks the minority vote without pre-engagement is negotiating against an adversarial shareholder base. Earlier, private engagement with key institutional shareholders before the board announcement changes the outcome.

The specific regulatory reference is SEBI (LODR) Regulations 2015, Regulation 37A (as amended), and Section 180(1)(a) of the Companies Act 2013.

Frequently asked questions

Q: Is a slump sale exempt from income tax?
A: No. A slump sale is taxable. The seller’s capital gain is computed under Section 50B of the Income Tax Act 1961, using the net-worth method. Profits are taxed as long-term capital gains at 12.5% (if the undertaking is held over 36 months) or at slab/corporate rates for STCG. The benefit of a slump sale is the computation mechanism, not a tax exemption.

Q: How is net worth computed for Section 50B purposes?
A: Net worth is the aggregate of the written-down value of all depreciable assets plus the book value of all other assets, reduced by the book value of the liabilities of the undertaking, as appearing in the books of the seller. Self-generated goodwill and revaluation of assets are excluded. A Chartered Accountant must certify the net worth in Form 3CEA.

Q: What is the cost and typical fee range for a slump sale advisory?
A: Fees depend on the complexity of the transaction: size, number of assets, FEMA involvement, going-concern documentation requirements, and SEBI applicability. At Treelife, we scope engagements specifically.

Q: How long does a slump sale typically take from LOI to closing?
A: A private company slump sale with no regulatory approvals: 6 to 10 weeks. A public company or listed company slump sale requiring Section 180 special resolution (and EGM notice period of 21 days minimum): 12 to 16 weeks. A slump sale requiring NCLT scheme sanction under Sections 230-232: 6 to 12 months.

Q: What documents are needed for a slump sale?
A: Business Transfer Agreement (BTA), Form 3CEA (CA-certified net worth report), Rule 11UAE valuation report (FMV1 and FMV2 computation), board and shareholder resolutions, counterparty novation consents for material contracts, employee transfer letters, GST ITC-02 filing, and stamp duty assessment for the BTA.

Q: Is Section 194-Q TDS applicable on slump sale consideration?
A: The position is unsettled. Section 194-Q requires a buyer whose turnover exceeds ₹10 crores to deduct TDS at 0.1% on purchases of goods exceeding ₹50 lakhs. Whether a slump sale consideration constitutes “purchase of goods” is fact-specific. A majority view holds that a slump sale is a transfer of a business undertaking, not a purchase of goods, and Section 194-Q does not apply. However, a formal tax opinion should be obtained before closing.

Q: Is there GST on a share sale?
A: No. Shares are securities, not goods or services, and their transfer is outside the scope of GST entirely. A share sale does not attract GST for either party.

Q: What FEMA forms must be filed in a cross-border share sale?
A: Form FC-TRS must be filed with the Authorised Dealer Bank within 60 days of receipt of consideration (for a resident seller selling to a non-resident) or within 60 days of payment (for a resident buyer acquiring from a non-resident). Additionally, the NRI or foreign seller requires Form 15CA and Form 15CB before the bank remits the sale proceeds overseas. An annual FLA return update is required if the Indian company’s FDI profile changes.

Q: Can accumulated business losses in a target company survive a share sale?
A: Subject to Section 79 of the Income Tax Act 1961. For a closely held company, if there is a change of more than 51% in the beneficial ownership of shares in a year, the carry-forward of business losses from years before that change is extinguished. This does not apply to unabsorbed depreciation, which survives ownership changes. Detailed analysis of the pre-acquisition shareholding pattern and the post-acquisition cap table is essential before pricing a loss-carrying target company in a share sale.

Q: What happens if the slump sale fails the “going concern” test for GST after closing?
A: CBIC can re-characterise the transfer as a supply of goods and services and demand GST, interest, and penalty. The penalty under Section 122 of the CGST Act 2017 for wrong availment of exemption can be up to 100% of the GST that would have been payable. The seller and buyer are jointly exposed. Post-closing going-concern documentation is the primary safeguard.

Q: How is stamp duty affected if I structure a slump sale through an NCLT scheme?
A: A Scheme of Arrangement under Sections 230-232 of the Companies Act 2013 approved by NCLT is exempt from stamp duty in some states under the local Stamp Act provisions. The availability of this exemption varies by state. In Maharashtra, for example, the stamp exemption for NCLT-sanctioned schemes has historically been available, subject to conditions. This is a material consideration for large slump sales involving significant immovable property.

Q: Can an NRI seller in a share sale claim DTAA benefits to reduce Indian capital gains tax?
A: Yes, if a Double Taxation Avoidance Agreement (DTAA) between India and the NRI’s country of residence has a capital gains article that eliminates or reduces Indian taxing rights on share gains. The India-Mauritius, India-Singapore, and India-UAE DTAAs have been frequently discussed in this context, though post-2016 amendments have restricted the Mauritius and Singapore treaty benefits for shares acquired after 01 April 2017. Each DTAA must be read on its own terms. The NRI must furnish a valid Tax Residency Certificate and a completed Form 10F to claim the treaty benefit.

Q: Does the majority-of-minority vote under SEBI LODR Regulation 37A apply to private limited companies?
A: No. Regulation 37A applies only to listed entities. Private limited companies are not subject to SEBI LODR regulations.

Q: What is the penalty for a missed FC-TRS filing in a share sale?
A: Under FEMA 1999, contravention of FEMA provisions can attract compounding penalty of up to 300% of the amount involved in the contravention. RBI and ED have pursued compounding proceedings for missed FC-TRS filings. The compounding process requires the company to apply to RBI, disclose the contravention, and pay the compounded amount. Late filings with a reasonable explanation are typically compounded at lower rates, but the process itself adds cost and delay.

Q: Can a buyer claim depreciation on goodwill acquired in a slump sale or asset purchase?
A: No. The Finance Act 2021 amended Section 32 of the Income Tax Act 1961 to explicitly exclude goodwill from the list of eligible depreciable intangible assets. This applies to goodwill acquired through any route: slump sale, asset purchase, or amalgamation. The ruling in Smifs Securities Ltd., which had allowed depreciation on purchased goodwill, was prospectively nullified by this amendment. A buyer who pays a significant premium over book value in any of the three structures derives no depreciation benefit from the goodwill component of the purchase price.

Q: Is a Section 281 No Objection Certificate needed in a slump sale as well as an asset sale?
A: The Section 281 risk is most acute in an asset sale, where specific assets change hands and could theoretically be attached by the income tax department for the seller’s pre-closing dues. In a slump sale, the buyer acquires the entire undertaking and becomes a successor under Section 170, which means the income tax department can proceed against the buyer directly for pending assessments. The practical protection in both cases is the same: obtain a tax due diligence certificate covering all open assessments, structure an escrow holdback to cover open demands, and confirm the seller’s indemnity extends through the full assessment proceedings period, not just a fixed post-closing tail. In a share sale, Section 281 does not directly apply because no assets are being transferred; all assets remain in the target company throughout.

Q: When is a demerger better than a slump sale?
A: A demerger is better when: (a) the seller company has a very low cost base in the undertaking, making the 12.5% LTCG on the Section 50B gain material and painful; (b) the objective is to create a standalone entity for a separate fundraise, separate listing, or long-term independent operation rather than an outright sale; (c) the undertaking has significant carry-forward losses that the new entity needs to preserve under Section 72A(4); or (d) the consideration must be in shares rather than cash, making the going-concern continuity of a tax-neutral demerger the appropriate structure. A demerger requires NCLT approval and takes 4 to 9 months, compared to 6 to 16 weeks for a slump sale. For any transaction where an acquirer is paying cash consideration, slump sale will almost always be the operative choice.

Q: Does MAT override the 12.5% LTCG rate on a slump sale?
A: It can. If the selling entity is a domestic company subject to Minimum Alternate Tax under Section 115JB of the Income Tax Act 1961, the slump sale gain forms part of book profit. MAT is charged at 15% of book profit (as of Budget 2026). Where the regular LTCG tax at 12.5% on the Section 50B gain is lower than the MAT liability, the company pays MAT instead. The MAT exposure should be modelled before the deal price is fixed, particularly for companies with large book surpluses relative to their written-down tax values. GIFT City companies pay reduced MAT at 9% under Budget 2026 amendments.

Q: Does the structure choice affect whether a CCI filing is needed?
A: It can. A slump sale or asset sale of a specific undertaking is assessed for CCI thresholds based on the assets and turnover of the transferred undertaking, not the parent company. If the undertaking falls below the CCI filing thresholds even though the parent company would not, no filing is required. A share sale of the parent entity is assessed on the parent’s aggregate financials, which may trigger the thresholds. The deal value threshold of ₹2,000 crores under the CCI Combinations Regulations 2024 applies to all three structures where total consideration globally exceeds that figure and the target has substantial Indian operations.
