M&A Deal Structures in India: 4 Types Compared 2026

Last verified: 18 June 2026

When two of India’s largest multiplex chains decided to combine, they did something that puzzled a lot of people watching from outside the deal room. They did not buy each other’s shares. They did not pick up cinemas one screen at a time. Instead, the lawyers reached for one of the heavier tools in Indian corporate law: a scheme of arrangement before the National Company Law Tribunal (NCLT) under Sections 230-232 of the Companies Act, 2013. They asked a tribunal to merge one company into the other by operation of law, with shareholders of the transferor receiving fresh shares in the surviving entity at a fixed swap ratio. The scheme was sanctioned. And on the appointed date, every asset, contract, cinema lease, employee and liability of the transferor vested automatically in the surviving company, without a single landlord being asked to sign a new agreement.

So why go through it? Why sit through months of NCLT hearings, creditor meetings and a Competition Commission of India (CCI) filing, when a share purchase agreement could have been signed in a few weeks? Because the structure was the deal. A statutory merger gave the two operators tax-neutral treatment on the combination, a share-swap that avoided a large cash outflow, the automatic transfer of thousands of cinema leases without renegotiating each one, and a single court order that bound even dissenting shareholders. A share deal could not have delivered all four at once. The choice of structure was not a footnote to the transaction. It was the transaction.

That single decision, merger rather than share purchase, sits at the heart of every Indian M&A transaction worth the name. Before anyone drafts a clause, the lawyers, the CFO and the tax team sit in a room and choose among four routes: a statutory merger, a slump sale, an itemised asset deal, or a share deal. The choice decides who pays capital gains tax and at what rate. It decides whether the buyer inherits hidden liabilities or cherry-picks clean assets. It decides whether stamp duty runs to lakhs or to crores, whether GST applies, whether the CCI must clear the deal, and whether closing takes three weeks or fifteen months. Indian M&A deal value has stayed in the hundreds of billions of dollars even as deal counts consolidate, and every one of those deals turned on this first decision. Get the structure wrong, and no amount of elegant drafting saves it.

Here’s the problem. The decision tool you actually need sits scattered across the current top results, and none of them assembles it in one place. Founder-first guides bury the comparison under ESOPs and reverse-flips. Tax portals explain only the slump sale. Law-firm notes give you the doctrine but leave you to synthesise the choice yourself. What follows is the four-way comparison built for law students, junior M&A associates and CS or CA professionals: a single side-by-side matrix across all six decision axes, a plain-English explainer of each of the types of M&A deal structures in India, the tax, stamp-duty, GST and regulatory mechanics that competitors split apart, the landmark Supreme Court cases that define a slump sale, and a “choose X if…” framework that turns all of it into a decision. If your deal happens to be cross-border, one structure below comes with a pointer to a dedicated guide.

The main types of M&A deal structures in India are four: a statutory merger or amalgamation (an NCLT-sanctioned scheme of arrangement under Sections 230-232 of the Companies Act, 2013), a slump sale (a lump-sum transfer of an entire business undertaking under the Income-tax Act), an asset deal (an itemised purchase of selected assets and liabilities), and a share deal (an acquisition of the target’s shares). They differ sharply on tax, liability transfer, stamp duty, GST, regulatory approvals and speed.

What are the types of M&A deal structures in India?

Four structures cover almost every Indian deal: the statutory merger, the slump sale, the asset deal and the share deal. That is the whole map. But to use it, you need to see the two distinctions that organise it, because every downstream consequence (tax, liability, stamp duty, GST, approvals, speed) flows from them.

Entity-level vs asset-level deals: the first fork

The first fork is what actually moves. In a share deal and a statutory merger, the entity moves: you are dealing in shares, or you are merging one company into another, so the business stays bundled inside its legal wrapper and travels whole. In a slump sale and an asset deal, the business or its assets move while the selling company stays where it is. Why does this matter so much? Because when the entity travels, everything inside it (every contract, licence, employee and liability) travels too, automatically. When only the business or the assets move, each piece has to be handed over, and that opens the door to picking and choosing.

This is also the line the landmark cases police. A slump sale moves a whole undertaking as a going concern for one lump sum. The moment you start assigning a value to each asset, you have crossed into an itemised sale, with very different tax. We’ll come back to that boundary, because two Supreme Court rulings turn on it.

Transfer by operation of law vs transfer by contract

The second distinction is how the transfer happens. A statutory merger transfers by operation of law: the NCLT’s sanction order vests the transferor’s assets and liabilities in the transferee automatically, with no separate conveyance for each one. The other three transfer by contract: a share purchase agreement, a business transfer agreement, or an itemised asset purchase agreement does the work, and third parties may need to consent. That single difference explains why a merger is slow but seamless, and why an asset deal is fast to start but slow to close (each consent is a negotiation of its own).

A quick word on terminology before the detail. People use “merger” and “amalgamation” almost interchangeably, and in practice the difference rarely bites. Both run through the same NCLT scheme route. We unpack the nuance in the merger section below. For now, hold onto the two forks (entity vs assets, law vs contract) and the six consequences they drive: tax, liability, stamp duty, GST, approvals and speed. Those six are the axes of the comparison that follows. One scope note: this guide covers domestic structures. If your share-swap crosses a border, the FEMA and RBI mechanics live in a separate guide we point to later, so this hub stays focused.

The four structures at a glance: merger vs slump sale vs asset deal vs share deal

Here is the comparison no single competitor lays out cleanly. Read it across, not down: each row is one decision axis, and each column is one of the four M&A deal structures in India. Scan it first to get your bearings, then use the sections below, where each structure gets its own explainer and each axis gets its own head-to-head.

[INFOGRAPHIC: ma-fourway-matrix]

Two things the table cannot hold in six columns. Stamp duty and GST deserve their own row each (we give them a dedicated table later), but the short version is that a slump sale is GST-exempt as a going concern while an itemised asset sale attracts GST, and a slump sale’s stamp duty is usually lower than an itemised conveyance. The other point is that “typical speed” is a rough guide, not a promise: consents, regulatory queues and listed-company processes all stretch it. Every row above is unpacked axis-by-axis in the comparison sections (tax, liability, stamp duty and GST, approvals, speed) so you can go deep on the one that decides your deal.

Statutory merger and amalgamation: the NCLT scheme route (Sections 230-232)

A statutory merger is the structure in the story above, and it is the only one of the four that needs a tribunal to bless it. That single feature, court sanction, is what gives it powers the other three cannot match: it binds dissenters, it transfers everything in one stroke, and it can carry the seller’s tax history forward. It is also why it is the slowest route. If you understand the merger, the other three are easier to place, because they are all defined partly by what they cannot do that a merger can.

Merger vs amalgamation vs demerger: what the terms mean

Start with the vocabulary, because clients use these words loosely. A merger (or amalgamation) combines two or more companies into one surviving entity. In strict usage, an amalgamation is two or more companies blending into one (sometimes a brand-new company), while a merger absorbs the transferor into an existing transferee. In practice the two terms are used interchangeably, and the same scheme route serves both. A demerger is the mirror image: a company splits off a business unit into a separate company, again through a scheme. So is a triangular or reverse-triangular merger a separate Indian category? Not really. Those are US-origin structuring concepts (a merger executed through a subsidiary or special-purpose vehicle), occasionally achieved in India via a scheme or an SPV, but they are not distinct statutory species under Indian law.

How an NCLT scheme of arrangement works (Sections 230-232)

The mechanism is a scheme of arrangement under Sections 230-232 of the Companies Act, 2013, sanctioned by the NCLT. At a high level, the process runs through a few defined stages.

1. The company applies to the NCLT proposing the scheme, with the swap ratio and a valuation report.
2. The tribunal directs meetings of shareholders and creditors (or dispenses with them where the law allows).
3. The required majorities approve the scheme at those meetings.
4. The NCLT hears objections, takes the views of statutory regulators, and sanctions (or refuses) the scheme.
5. On the appointed date, the scheme takes effect and the transferor’s assets and liabilities vest in the transferee.

This is newer than it looks. Until the Companies Act, 2013 framework came into force, schemes of arrangement were sanctioned by the High Courts. Jurisdiction shifted to the NCLT when the relevant provisions were notified in 2016, consolidating merger sanctioning in a specialist forum. That shift is why older case law refers to High Court sanction while current practice is entirely NCLT-driven. Keep it structural, though: this is a comparison, not a step-by-step filing manual, and the point is simply that a merger needs a tribunal while the other three do not.

Fast-track mergers under Section 233: the simplified route

Not every merger needs the full scheme. When the Companies Act, 2013 provisions were notified on 15 December 2016, they introduced a fast-track route under Section 233 of the Companies Act, 2013 for mergers between small companies, and between a holding company and its wholly-owned subsidiary. This route skips the NCLT hearing in the ordinary case: the scheme is approved by the members and creditors and then by the Regional Director (with the Registrar and Official Liquidator in the loop), and it only escalates to the NCLT if an objection has merit. For a group reorganisation between a parent and its subsidiary, this can shave months off the timeline. In practice, it is one of the reasons re-domiciliation and intra-group clean-ups increasingly run through the merger route rather than an asset transfer.

Why a merger transfers everything “by operation of law”

Here’s the defining trait. On the appointed date, the transferor’s entire estate (property, rights, contracts, leases, licences, employees and liabilities) vests in the transferee automatically, by operation of law, because the court order says so. You do not assign each lease. You do not chase each landlord. This is not a matter of practice but of statute: Section 232(3) of the Companies Act, 2013 provides that where the tribunal’s order so directs, the transferor’s property and liabilities are transferred to and vest in the transferee company without any further act or deed. That is also why a scheme can bind dissenting and minority shareholders: once the required majority approves and the tribunal sanctions, the holdout is carried along, the principle the Supreme Court settled in Miheer H. Mafatlal v. Mafatlal Industries Ltd., (1997) 1 SCC 579, where the Court held a sanctioned scheme binding on the dissenting minority and confined the court’s role to supervisory, not appellate, review of the majority’s commercial wisdom. The adjacent mechanic worth knowing here is the squeeze-out of residual minority holders, and LawSikho’s guide on how dissenting and minority shareholders are dealt with in a scheme goes deeper than we can here.

The flip side of “everything vests” is that everything vests, liabilities included. You cannot ring-fence in a merger the way you can in an asset deal. The trade-off is built into the structure: you get tax neutrality and continuity, and in return you accept the full estate and the long timeline. On tax, a merger that meets the conditions is tax-neutral, and the transferee can carry forward the transferor’s accumulated losses and unabsorbed depreciation subject to conditions. We hold the detail for the tax section. And does a slump sale need an NCLT order to do any of this? It does not, which is exactly the contrast the next section opens with.

Slump sale: the lump-sum business transfer (Section 2(42C) and Section 50B)

The slump sale is the most searched-for single structure on this list, and for good reason: it is the workhorse of Indian business carve-outs. When a company wants to hive off a whole vertical (a product line, a plant, a service division) without merging entities or itemising every asset, the slump sale is usually the efficient answer. It is also the structure where the tax rules are most specific, where a 2021 overhaul changed the maths, and where the new Income-tax Act, 2025 (in force from 1 April 2026) has re-codified the provisions practitioners grew up citing. Let’s take it apart.

What is a slump sale? Section 2(42C) and the going-concern test

A slump sale is the transfer of one or more undertakings as a going concern, for a lump-sum consideration, without assigning values to individual assets and liabilities. That definition (historically in Section 2(42C) of the Income Tax Act, 1961, and now carried into the definitions clause of the Income-tax Act, 2025, which retains the same “transfer of one or more undertakings, by any means, for a lump sum consideration without values being assigned to the individual assets and liabilities” formulation) is doing precise work. The phrase “as a going concern” means the undertaking moves as a living, operating business, with its assets, liabilities, contracts and (typically) employees travelling together as a bundle. The phrase “no values assigned to individual assets” is the line that separates a slump sale from an asset deal, and it is exactly what the courts have litigated. In CIT v. Electric Control Gear Mfg. Co., (1997) 227 ITR 278 (SC), the principle that a going-concern sale for a lump sum, with no separate values, is a slump sale rather than an itemised sale was put on a firm footing, and the Supreme Court authority in PNB Finance Ltd. v. CIT, (2008) 307 ITR 75 (SC) remains the leading reference on slump-sale classification.

Capital gains on a slump sale: net worth, no indexation

The tax mechanics live in what practitioners still call Section 50B, now re-enacted as Section 77 of the Income-tax Act, 2025 (the re-enacted Section 50B of the Income Tax Act, 1961). The computation is unusual: capital gains equal the sale consideration minus the net worth of the undertaking, where net worth is broadly the aggregate book value of assets minus the value of liabilities of that undertaking. No indexation is available, which surprises people who expect to inflation-adjust the cost. So if you transfer a vertical for a lump sum and its net worth is a smaller figure, the gap is your capital gain, computed in one shot rather than asset by asset.

Here’s a stripped-down illustration of the shape. Suppose the lump-sum consideration is the agreed price for the whole undertaking, and the net worth (assets minus liabilities of that undertaking, computed under the statutory rules) is a lower figure. The capital gain is simply consideration minus net worth, taxed without indexation. And this is where a quiet shift is happening: as FMV-based slump-sale taxation and the new Income-tax Act, 2025 bite, the premium has moved toward juniors who can model tax across structures rather than merely document the deal. The lawyer who can sit with the net-worth schedule and stress-test the gain across a slump sale, an asset deal and a share deal is now worth more than the one who only drafts the agreement.

On the holding period, the slump-sale rule is deliberately its own animal. An undertaking held for more than 36 months qualifies for long-term capital gains treatment, and the long-term rate is 12.5% without indexation. Worth flagging clearly: even though the general holding period for long-term status was rationalised to 24 months by the Finance (No. 2) Act, 2024, the slump-sale provision retains the longer more-than-36-month test. That is not a typo to be “corrected” down to 24 months. It is the rule.

How the Finance Act 2021 rewrote slump sale (FMV, slump exchange, goodwill)

The Finance Act, 2021 reshaped this structure in three ways that still govern it under the 2025 Act’s re-codification. First, the slump-sale definition was widened from “sale” to “transfer by any means”, which brought a slump exchange (transferring an undertaking for non-cash consideration, such as shares) squarely within the slump-sale net; previously, taxpayers had argued an exchange fell outside it. Second, the consideration is now deemed at fair market value computed under Rule 11UAE, closing the gap where parties under-stated the price to suppress the gain. Third, goodwill was removed from the block of depreciable assets, which feeds back into the net-worth computation. These remain the lineage that the Income-tax Act, 2025 carries forward, so a reader who knows the old numbers can still follow the logic. For how the new Act re-numbers and re-frames these provisions, LawSikho’s guide on how the new Income-tax Act 2025 re-codifies these capital-gains provisions tracks the transition in detail.

The Business Transfer Agreement and what a slump sale can carve out

The instrument that effects a slump sale is the Business Transfer Agreement (BTA): a single agreement to transfer the undertaking as a going concern for a lump sum. It is purely contractual, which answers one of the most common questions head-on. Does a slump sale need NCLT approval? No. There is no tribunal, no scheme, no court order; the parties sign a BTA and close. That is a major speed and approval advantage over a merger.

Can a slump sale still carve things out? Within limits, yes. A slump sale can exclude certain assets or liabilities and remain a slump sale, provided what transfers is genuinely a whole undertaking capable of running as a going concern; you simply cannot start pricing each asset separately without tipping into an itemised sale. A common practitioner use of the structure is converting a partnership firm or a proprietary business into a company by slumping the business into a newly formed company, a clean way to incorporate an operating business. The going-concern character is also why the GST and stamp-duty treatment is favourable, which we cover in the dedicated section: one line for now, a going-concern transfer is GST-exempt and a BTA usually attracts lower stamp duty than an itemised conveyance.

Asset deal: the itemised purchase (cherry-picking assets and liabilities)

If the slump sale is the whole-undertaking route, the asset deal is its itemised cousin, and the two are the most-confused pair in Indian M&A. The difference is not academic. It changes the tax, the stamp duty, the GST and, above all, what the buyer is exposed to. The asset deal exists for one dominant reason: control. When a buyer wants to choose exactly what it takes and what it leaves behind, this is the structure that allows it.

What is an asset (itemised) deal, and how it differs from a slump sale

In an asset deal, the buyer purchases selected assets and assumes only selected liabilities, with each asset conveyed and, crucially, often valued individually. That individual valuation is the whole ballgame. The moment specific values are assigned to specific assets, the transaction is an itemised sale, not a slump sale, with capital gains computed asset by asset rather than on net worth. This is exactly the boundary the Supreme Court drew in CIT v. Artex Manufacturing Co., (1997) 227 ITR 260 (SC): where the value of individual assets is ascertainable and assigned, the transaction is treated as an itemised sale rather than a slump sale. So the same set of assets can be sold two ways, with two very different tax outcomes, depending solely on whether you priced them as a bundle or one by one. The documentation that captures either route, the asset purchase agreement or the share purchase agreement, is its own discipline, and LawSikho’s guide on the agreements that document a share or asset acquisition is a useful companion when you reach the drafting stage.

Cherry-picking assets and ring-fencing liabilities: the buyer’s advantage

Why accept the extra cost and friction of itemising? Because the asset deal lets the buyer cherry-pick assets and ring-fence liabilities, and that is worth a great deal when the target is risky. Picture an acquirer eyeing a distressed business with a tangle of legacy claims, disputed dues and contingent exposures of uncertain size. In a share deal, all of that would transfer with the company. In an asset deal, the buyer takes the plant, the brand and the customer book it wants, declines to assume the liabilities it does not, and leaves the legacy mess with the seller. That single feature, the ability to decline unknown and legacy liabilities, is the main reason a buyer accepts the higher friction of an itemised deal. For an acquirer worried about what it cannot see in diligence, ring-fencing is not a nicety. It is the point.

The price of flexibility: GST, stamp duty and lost tax attributes

That flexibility has a bill attached, and it lands in three places. First, GST applies to an itemised asset sale (commonly at 18% on movable assets), because itemised assets are a taxable supply rather than the transfer of a going concern. Second, stamp duty is typically higher, because each immovable asset is conveyed and stamped individually instead of a single business being transferred under one BTA. Third, and this is the one buyers underestimate, the seller’s tax losses and credits do NOT carry over to the buyer in an asset deal; you buy assets, not tax history, so any accumulated losses or unabsorbed depreciation stay behind with the seller. The full GST and stamp-duty mechanics sit in their own section below.

There is also a transfer-of-relationships problem that the going-concern structures avoid. In an asset deal, contracts, licences and employees do not move automatically. Each material contract may need third-party consent or a fresh assignment, key licences may require re-issue or transfer applications, and employees do not transfer by operation of law the way they do as part of a going-concern bundle; they typically have to be offered fresh employment. That is the practical contrast with a slump sale, where the going-concern character carries the contract and employee bundle across together. So the asset deal trades clean liability protection for messy transfer logistics, and whether that trade is worth it is a deal-by-deal call. We’d recommend mapping the count of consents and licences early: on a contract-heavy target, that logistics burden alone can be the reason a buyer reaches for a slump sale or a share deal instead.

Share deal: acquiring the target’s shares

The share deal is the default. More Indian acquisitions are structured as share purchases than as any other route, and once you see why, the rest of the comparison falls into place by contrast. The logic is simple: in a share deal, the company itself does not change. Only its owner does. Everything the company holds and owes stays exactly where it is, because the legal entity is untouched.

What is a share deal, and why it is India’s default M&A structure

In a share deal, the acquirer buys the shares of the target company, and the company (with everything it owns and everything it owes) continues unchanged. No business is conveyed, no assets are itemised, no scheme is filed; the ownership of the shares simply shifts from seller to buyer. The instrument is the Share Purchase Agreement (SPA), which sets the price, the conditions, and the all-important representations, warranties and indemnities.

So why is this the most common structure? Three reasons, mostly. It is simple, because you transfer one thing (shares) rather than a basket of assets. It preserves continuity, because contracts, licences, registrations and employees stay with the company and do not need re-assignment (subject only to any change-of-control clauses that a counterparty may have negotiated). And it minimises third-party consents, because the contracting entity is unchanged, so most counterparties have nothing to sign. For a clean, going target, that combination is hard to beat, and it is why the share deal is the path of least resistance for the majority of Indian deals.

The catch: inheriting every liability with the company

But there is a catch, and it is a big one. Because the entity is unchanged, the buyer inherits all of the target’s liabilities, including the hidden and contingent ones nobody flagged. A tax demand from an old assessment year, an undisclosed litigation, a contingent guarantee: in a share deal, they all come with the company, automatically. That is why due diligence is most intense in a share deal, and why the SPA’s representations, warranties and indemnities carry the weight they do; they are the buyer’s only real protection, since it cannot ring-fence the way an asset buyer can. The practical reality is that a share deal shifts the risk of the unknown onto the buyer, and the buyer manages that risk through diligence and contract, not through structure.

On tax, the seller pays capital gains on the transfer of shares, and the company’s accumulated losses survive at the company level, subject to the shareholding-continuity rules that restrict carry-forward when ownership changes substantially. That is a real contrast with an asset deal, where the losses simply die. We pull all four structures’ tax treatment together in the next section.

Cash vs share-swap consideration

How the buyer pays also matters. A cash deal is clean and final: the seller exits, the buyer owns the company, done. A share-swap deal (the buyer issues its own shares as consideration) keeps the seller invested in the combined future, can defer the seller’s cash tax in the right structure, and is the natural choice when the parties want continuity rather than a clean break, which is exactly why the multiplex merger in the opening used a swap. The trade-off is that a swap dilutes existing shareholders and ties the seller’s outcome to the buyer’s performance. And if your share-swap is cross-border, the rules change materially: if your share-swap is cross-border, the FEMA and RBI rules are covered separately, because pricing, reporting and entry-route compliance under exchange-control law sit outside this domestic comparison. Speed-wise, the share deal is usually the fastest structure to close, because there is no NCLT and few consents, a point the speed section returns to.

Tax compared: capital gains, neutrality and loss carry-forward across the four structures

Tax is the axis that decides more structures than any other, and it is also the one competitors scatter across separate PDFs. Pull it into one frame and the choices sharpen immediately. The real question is rarely “which structure is tax-efficient in the abstract” but “tax-efficient for whom, and does the seller’s loss history matter to anyone.” Let’s compare the four directly. (A note on currency: tax provisions here are stated under the Income-tax Act, 2025, in force from 1 April 2026, with the familiar 1961-Act section numbers in brackets for readers who learned them that way.)

Are mergers tax-neutral? The Section 47 and Section 72A conditions

A qualifying merger is tax-neutral: the transfer of the transferor’s assets to the transferee, and the issue of shares to the transferor’s shareholders, are not treated as taxable transfers if the statutory conditions are met. Those conditions historically lived in Section 47(vi) and (vii) of the Income Tax Act, 1961, now re-codified as Section 70 of the Income-tax Act, 2025 (transactions not regarded as transfer, which carries forward the amalgamation and share-swap neutrality clauses), and they require, broadly, that the amalgamated company be Indian and that the specified shareholder-continuity tests be satisfied.

On top of neutrality, the transferee can carry forward the transferor’s accumulated losses and unabsorbed depreciation under the provision practitioners know as Section 72A of the Income Tax Act, 1961, re-enacted for ordinary amalgamations as Section 116 of the Income-tax Act, 2025 (treatment of accumulated losses and unabsorbed depreciation in amalgamation or demerger), subject to conditions on continuity of business and holding. One change matters for current deals: for amalgamations effected on or after 1 April 2025, the accumulated loss carries forward for only the balance of eight assessment years counted from the year the loss was first computed for the original entity, not a fresh eight-year run from the year of amalgamation, so the carry-forward window is narrower than the old regime allowed.

A separate provision, Section 117 of the Income-tax Act, 2025 (re-codifying the old Section 72AA), governs the special case of a banking-company amalgamation or an amalgamation following strategic disinvestment, and should not be read as the general rule. Even with the tighter cap, that general carry-forward is one of the most valuable features of the merger route, and it has no equivalent in an asset deal.

Slump sale vs asset deal vs share deal: how capital gains differ

The three non-merger routes each tax differently. In a slump sale, the gain is consideration minus net worth, computed under Section 77 of the Income-tax Act, 2025 (the re-enacted Section 50B), with no indexation and FMV deemed as consideration; the gain sits with the seller. In an asset deal, capital gains are computed asset by asset, so the character (capital asset, depreciable block, stock) and gain of each item are worked out separately, again taxed in the seller’s hands. In a share deal, the seller pays capital gains on the shares, and the rate and holding-period treatment follow the share-specific rules. Three routes, three different computations, one recurring theme: the seller usually bears the gain, but the shape of that gain (and the buyer’s downstream position) changes completely with the structure.

Where do tax losses survive, and where do they die?

This is the part that most often flips a decision. In a merger, losses can transfer to the transferee under the Section 72A route. In a share deal, the company’s losses survive at the entity level because the company is unchanged, subject to the shareholding-continuity restriction (historically Section 79) that curtails carry-forward when ownership shifts substantially. But in an asset deal, the buyer’s position is stark: tax losses and credits do not transfer at all; they stay with the seller. So if the target carries valuable accumulated losses, an asset deal quietly throws them away, while a share deal or a merger may preserve them. That is why “which is most tax-efficient” has no universal answer. It depends on whether you are buyer or seller, and on whether the seller’s losses are worth carrying. Based on what we’ve seen, the loss question is the single factor most often left until too late, and it can quietly swing a deal from one structure to another. Hold that thought; the decision framework turns it into a rule.

Liability transfer compared: who inherits what

If tax decides the most structures, liability decides the most anxious ones. When a buyer cannot be sure what is lurking in a target (an old tax exposure, a contingent claim, an environmental issue), the structure it chooses determines whether that risk lands on its books or stays with the seller. This is the cleanest four-way contrast in the whole comparison, and no competitor lays it out as one matrix. So here it is.

The four-way liability matrix: automatic vs cherry-pick vs going-concern vs vesting

Each structure handles liabilities in its own way. In a share deal, all liabilities are inherited automatically, because the company (and everything it owes) is unchanged; the buyer steps into the seller’s shoes entirely. In an asset deal, the buyer assumes only the liabilities it contractually agrees to take, so unknown and legacy liabilities can be left behind, the cherry-pick advantage in full. In a slump sale, all of the undertaking’s liabilities transfer as part of the going concern, because the business moves as a bundle; you have less cherry-pick freedom than an asset deal, though the liabilities are confined to that undertaking rather than the whole selling entity. And in a statutory merger, all assets and liabilities of the transferor vest in the transferee by operation of law on the NCLT order, with no ability to exclude.

Ring-fencing liabilities, and why due diligence differs by structure

So how do you actually ring-fence in practice? Genuine ring-fencing, leaving liabilities behind, is possible only in an asset deal, by excluding specific liabilities in the asset purchase agreement and assuming only what you want. In a share deal or a merger, you cannot exclude anything; instead you manage inherited risk through contractual tools: detailed representations and warranties, specific indemnities, holdbacks, escrow and price adjustments. That difference reshapes the diligence itself. In a share deal, diligence has to be exhaustive, because anything you miss, you own; you scrub tax, litigation, contingent liabilities, related-party dealings and contractual change-of-control triggers, since there is no structural escape hatch. In an asset deal, diligence is narrower and asset-focused, because you can simply decline the liabilities you are unsure about, though you still verify title and transferability of each asset and contract. The mistake we see most often is treating diligence intensity as fixed regardless of structure. It is not. The structure sets how deep you must dig.

Stamp duty and GST compared: the hidden cost difference

Here’s where deals quietly gain or lose crores, and where most explainers give you only half the picture. Stamp duty and GST are not afterthoughts to the structure choice; for asset-heavy businesses they can move the economics enough to flip the decision. The useful thing is not just what the treatment is, but why it differs, because the “why” is what lets you predict the treatment for a deal you have not seen before. Let’s take GST and stamp duty in turn.

GST: why a going-concern slump sale is exempt and an asset sale is not

The GST contrast turns on one idea: is this the transfer of a going concern, or the supply of itemised goods? A slump sale (the transfer of a business as a going concern) is exempt from GST under Notification 12/2017 (Central Tax (Rate)), Entry 2, which exempts the service of transferring a going concern. An itemised asset sale is the opposite: it is a supply of goods, so GST applies, commonly at 18% on the movable assets being sold. A statutory merger is outside GST, because the transfer happens by operation of law rather than as a supply, and a share deal is outside GST too, because the transfer of securities is not a supply of goods or services. So the same underlying business can be GST-exempt or GST-bearing depending purely on whether it moves as a going concern or as a pile of itemised assets, which is a powerful reason to prefer the slump-sale route where the facts allow it.

Stamp duty: why a BTA costs less than an itemised conveyance

Stamp duty is a state subject, so the exact rates vary across states, and there is no single national figure. But the mechanism is consistent enough to reason about. A slump sale is effected by a Business Transfer Agreement, an agreement to transfer a business for a single lump-sum price with no per-asset values, and that single instrument generally attracts lower duty than the alternative. An itemised asset deal, by contrast, conveys each immovable asset separately, and each conveyance is stamped, so the duty stacks up asset by asset and tends to be higher overall. The reason no individual asset value is assigned in a slump sale (the going-concern, lump-sum character) is the very feature that keeps it out of itemised-conveyance duty, which ties this section back to the classification cases. Give the mechanism the weight, not a rate table, because the numbers shift by state.

Stamp duty on an NCLT merger order, and the two-state double-duty trap

Mergers have their own stamp-duty wrinkle. An NCLT scheme order is itself stamped as a conveyance instrument in most states, at state ad-valorem rates, because the order transfers property; the court sanction does not make it duty-free. And here is the trap that surprises even experienced teams: when the transferor and transferee are in different states, and the scheme is sanctioned by tribunals or stamped in both, the deal can face a double stamp-duty exposure, paying conveyance duty in more than one state on the same transfer. States have been tightening their treatment of BTAs and NCLT orders as conveyance instruments, which is steadily narrowing the slump-sale stamp-duty advantage and, in some cases, pushing carve-outs back toward scheme or merger routes where the overall cost works out better. So the stamp-duty edge that makes a slump sale attractive today is not a permanent law of nature; it is a state-by-state position that is moving.

Regulatory approvals compared: NCLT, CCI and SEBI

The structure you choose does not just change your tax bill. It changes which regulators you have to face, and that is the layer most structure explainers leave out entirely. A private slump sale of a small business may need almost no regulatory clearance, while a listed-company merger can trigger all three of NCLT, CCI and SEBI. Knowing in advance which doors a structure forces you to knock on is part of choosing it. So map the approvals to the structures.

NCLT: needed for mergers, not for the other three

This one is binary and worth stating plainly. The NCLT is mandatory only for a statutory merger or scheme under Sections 230-232; a slump sale, an asset deal and a share deal need no NCLT involvement at all, because they are contractual transfers, not court-sanctioned schemes. That is a major speed and approval differentiator: the moment you pick the merger route, you accept a tribunal process; the moment you pick any of the other three, you skip it. For many deals, that single fact is enough to rule the merger in or out before any other axis is weighed.

CCI merger control and the 2024 Deal Value Threshold

Competition clearance, by contrast, can attach to any structure. The CCI’s merger-control regime is triggered when the parties cross asset or turnover thresholds, and that can happen whether the deal is a share purchase, an asset purchase, a slump sale or a merger; the structure is not what triggers the CCI, the size is. The significant recent change is the Deal Value Threshold (DVT), which now requires notification where a transaction’s deal value exceeds ₹2,000 crore and the target has substantial business operations in India, catching large deals that might previously have slipped under the asset/turnover tests. The de-minimis (small-target) exemption still spares deals where the target’s assets or turnover fall below the prescribed small-target limits, but that exemption is not available to a deal caught by the DVT. Early signals suggest the CCI’s evolving “material influence” approach and a maturing DVT regime are likely to pull more minority and structured deals into merger control over the next few years, which means structure choice and competition strategy increasingly have to be decided together, earlier in the timeline.

SEBI open offers: when a share acquisition in a listed company triggers a mandatory offer

The third regulator is SEBI, and it shows up mainly when the target is listed. Under the SEBI takeover code, acquiring shares or control in a listed company can trigger a mandatory open offer to public shareholders, typically when the acquirer crosses 25% of voting rights, makes a creeping acquisition beyond the permitted annual limit, or acquires control of the company. That makes the open offer primarily a concern for share deals in listed targets, and for mergers involving listed companies; a private-company slump sale or asset deal does not raise it. The thresholds and process sit within the broader listed-company regulatory framework, and LawSikho’s note on the latest SEBI regulatory changes for listed-company deals is worth a read where a listed target is involved. The synthesis across all three regulators is simple: the structure changes which regulators you face, so a private slump sale may need none of NCLT or SEBI and only the CCI if it is large, while a listed-company merger may need all three.

Speed, timeline and business continuity compared

The last two axes are the ones clients ask about first and lawyers weigh last: how fast can we close, and will the business keep running through it? They matter because they are the practical tie-breakers when two structures look similar on tax and liability. And they often pull in the opposite direction from the optimal tax or liability structure, which is exactly the tension the decision framework has to resolve.

Which structure closes fastest, and why the NCLT route is slowest

On speed, the ranking is fairly stable. A share deal is usually fastest, often a matter of weeks, because there is no tribunal and few third-party consents. A slump sale or an asset deal sits in the middle, weeks to a few months, because they are contractual but depend on consents (and the asset deal’s per-asset consents can drag it out). A statutory merger is the slowest by a wide margin, because the NCLT scheme runs through meetings, regulator inputs, hearings and sanction, commonly taking many months and not infrequently more than a year. Why so slow? Because court sanction is the price of the merger’s superpowers (binding dissenters, vesting everything by operation of law, tax neutrality), and that process simply takes time.

Business continuity: which structures keep contracts, licences and employees in place

Continuity runs almost opposite to speed in places. A merger and a share deal offer the highest continuity, because the entity survives, so contracts, licences and employees stay in place without re-assignment. A slump sale offers high continuity too, because the going-concern transfer carries the contracts and employees across as a bundle, even though it is not the same entity. An asset deal offers the lowest continuity, because each contract and licence may need fresh consent or assignment and employees do not transfer automatically. Here’s the trade-off in one line: the merger gives you continuity and tax neutrality but is slow, the share deal gives you speed and continuity but inherits every liability, and the asset deal gives you liability protection but sacrifices both continuity and speed. No structure wins on every axis, which is precisely why you need a method to choose.

Decision framework: choose the right M&A structure (choose X if…)

Six axes are a lot to hold in your head at deal speed, so this section turns them into a decision. First, the quick version, a “choose X if…” rule for each structure. Then a five-step process for working through a live deal. There is no universally “best” structure; the right one is simply the structure whose six-axis profile matches your deal’s priorities, and the job is to match them deliberately rather than by habit.

Choose X if… the four decision rules

Use these as a first cut, then pressure-test with the five-step process below.

1. Choose a statutory merger if you need tax-neutral share-swap continuity, automatic transfer of all contracts and leases, and a court order that binds dissenters, and you can absorb a long NCLT timeline.
2. Choose a slump sale if you are transferring a whole business vertical as a going concern, you want GST exemption and lower stamp duty, and you do not need to carry the seller’s tax losses across to the buyer.
3. Choose an asset deal if you must ring-fence unknown or legacy liabilities, or buy only selected assets, and you accept GST, higher stamp duty and lost tax attributes as the price of that control.
4. Choose a share deal if you want speed, full business continuity and minimal third-party consents, and you are comfortable inheriting all liabilities, backed by thorough due diligence, representations and indemnities.

A five-step process for selecting your M&A structure

When a real deal lands on your desk, work through it in order rather than reaching for the structure you used last time.

1. Identify buyer vs seller priorities and who bears the tax. Establish whose tax position drives the deal and what each side most needs from the structure.
2. Map the liabilities, known vs unknown, and decide whether ring-fencing is essential. If unknown or legacy liabilities are a real risk, that pushes hard toward an asset deal.
3. Test the tax outcome across structures. Run neutrality, loss carry-forward, GST and stamp duty for a merger, a slump sale, an asset deal and a share deal, and compare the net cost.
4. Check the regulatory triggers. Identify whether the deal needs NCLT (merger only), CCI (any structure if thresholds or the DVT are met), and a SEBI open offer (listed targets).
5. Weigh speed and continuity against the optimal tax and liability structure, then choose. Where the fastest or most continuous route is not the most tax-efficient, decide consciously which axis wins for this deal.

Resolving the confusing pairs: slump sale vs asset sale, demerger vs slump sale

A few comparisons trip people up every time, so resolve them head-on. Slump sale vs asset sale: both move a business or its assets, but a slump sale transfers a whole undertaking for a lump sum with no per-asset values (GST-exempt, lower stamp duty, no loss transfer), while an asset sale itemises and values each asset (GST applies, higher stamp duty, full cherry-pick of liabilities). Asset deal vs share deal for the buyer: the asset deal buys liability protection at the cost of lost tax attributes and GST, while the share deal buys speed and continuity at the cost of inheriting everything. Demerger vs slump sale: a demerger is a court-sanctioned scheme that splits a business unit into a separate company (with its own tax-neutrality regime for a qualifying demerger), whereas a slump sale is a contractual sale of an undertaking for a price, so the demerger suits a tax-neutral internal split and the slump sale suits an outright sale to a third party. The better approach, in our view, is to let the deal’s dominant priority pick the structure, then use the other five axes to confirm or veto, rather than starting from a structure you already like.

Frequently asked questions about M&A deal structures in India

What are the main types of M&A deal structures in India? There are four: a statutory merger or amalgamation (an NCLT scheme under Sections 230-232 of the Companies Act, 2013), a slump sale (a lump-sum going-concern transfer), an asset deal (an itemised purchase of selected assets and liabilities), and a share deal (an acquisition of the target’s shares). They differ on tax, liability, stamp duty, GST, approvals and speed.

What is the difference between a slump sale and an asset sale? A slump sale transfers a whole undertaking as a going concern for a single lump sum, with no values assigned to individual assets. An asset sale is itemised: each asset is valued and conveyed separately, which lets the buyer cherry-pick assets and liabilities but attracts GST and usually higher stamp duty. The presence or absence of per-asset values is the dividing line.

What is the difference between a merger and an amalgamation? In practice the terms are largely interchangeable. Strictly, an amalgamation is two or more companies combining into one (sometimes a new company), while a merger absorbs one company into another existing one. Both are achieved through the same NCLT scheme of arrangement under the Companies Act, 2013.

What is a slump sale under Section 50B of the Income Tax Act? A slump sale is the transfer of an undertaking as a going concern for a lump-sum consideration. The capital-gains computation, historically under Section 50B of the Income Tax Act, 1961 and now re-enacted as Section 77 of the Income-tax Act, 2025, takes the gain as consideration minus the net worth of the undertaking, with no indexation available.

Does a slump sale require NCLT approval? No. A slump sale is purely contractual, effected through a Business Transfer Agreement between the parties. Only a statutory merger or scheme of arrangement needs NCLT sanction; a slump sale, an asset deal and a share deal all close without any tribunal involvement.

Are mergers tax-neutral in India? Yes, where the conditions are met. The transfer in a qualifying amalgamation is not treated as a taxable transfer under the Section 47 conditions of the Income Tax Act, 1961 (re-codified as Section 70 of the Income-tax Act, 2025), and the transferee can carry forward the transferor’s accumulated losses and unabsorbed depreciation under the Section 72A route (re-codified for ordinary amalgamations as Section 116 of the Income-tax Act, 2025), subject to continuity conditions and an eight-year cap counted from the year the loss was first computed.

In which M&A structure does the buyer inherit all liabilities? A share deal. Because the company is unchanged, every liability, including hidden and contingent ones, transfers automatically with it. A statutory merger also vests all liabilities in the transferee by operation of law, so both leave the buyer holding the full liability set, unlike an asset deal where the buyer assumes only what it agrees to.

How is capital gains computed in a slump sale? The gain is the sale consideration minus the net worth of the undertaking. Since the Finance Act, 2021, the consideration is deemed at fair market value computed under Rule 11UAE, and no indexation benefit is available. Net worth is broadly the book value of the undertaking’s assets minus its liabilities, computed under the prescribed rules.

Is GST applicable on a slump sale? No. The transfer of a business as a going concern is exempt under Notification 12/2017 (Central Tax (Rate)), Entry 2. An itemised asset sale is different: it is a supply of goods and attracts GST, commonly at 18% on the movable assets, which is one of the cost reasons buyers weigh a slump sale against an asset deal.

How much stamp duty applies to a slump sale vs a conveyance? Stamp duty is a state subject, so rates vary, but the mechanism is consistent: a slump sale via a Business Transfer Agreement generally attracts lower duty than an itemised conveyance, where each immovable asset is conveyed and stamped separately. An NCLT merger order is itself stamped as a conveyance at state ad-valorem rates.

Can financial fraud or hidden liabilities be avoided by choosing an asset deal? An asset deal lets the buyer cherry-pick assets and decline to assume unknown or legacy liabilities, leaving them with the seller. That liability protection is the main reason a buyer accepts an asset deal’s higher GST and stamp-duty cost, particularly when acquiring a distressed or opaque target where diligence cannot fully map the risk.

Slump sale vs share sale: which is more tax-efficient? It depends on whether you are buyer or seller and whether losses matter. A share sale keeps the company’s accumulated losses alive at the entity level (subject to continuity rules), while a slump sale taxes the net-worth gain in the seller’s hands without transferring losses to the buyer. There is no universal answer; you model both for the specific deal.

Asset deal vs share deal: which is better for the buyer? An asset deal gives the buyer liability protection (cherry-pick and ring-fence) but costs lost tax attributes, GST and higher stamp duty, and breaks contract and employee continuity. A share deal gives speed and full continuity but makes the buyer inherit all liabilities. The better choice turns on how risky the target’s liability profile is.

Merger vs acquisition: what’s the difference? A merger combines two entities into one, usually through an NCLT scheme of arrangement. An acquisition is one company taking control of another, achieved through a share purchase, an asset purchase or a slump sale. So “merger” is one specific structure, while “acquisition” is the broader goal that several structures can deliver.

When is CCI approval triggered in an M&A deal? When the parties cross the prescribed asset or turnover thresholds, or under the 2024 Deal Value Threshold, where the deal value exceeds ₹2,000 crore and the target has substantial Indian operations. The de-minimis small-target exemption can spare smaller deals, but it is not available where the Deal Value Threshold is triggered.

When is a SEBI open offer triggered? Under the SEBI takeover code, a mandatory open offer to public shareholders is triggered on acquiring 25% or more of the voting rights in a listed company, on a creeping acquisition beyond the permitted annual limit, or on acquiring control of the company. It is primarily a concern for share deals and mergers involving listed targets.

What is the holding-period rule for long-term capital gains on a slump sale? An undertaking held for more than 36 months qualifies for long-term capital gains treatment on a slump sale; a shorter holding period is short-term. This longer test is specific to the slump-sale provision and was retained even after the general long-term holding period was rationalised to 24 months by the Finance (No. 2) Act, 2024.

At what rate is long-term capital gain on a slump sale taxed? Long-term capital gain on a slump sale is taxed at 12.5% without indexation. Because tax rates and provisions can change, and the Income-tax Act, 2025 has re-codified these rules, the current rate should be verified for any live transaction before it is relied on.
