A promoter who spent eighteen years building a mid-sized auto-components company in Pune finally gets the call every founder half-expects and half-dreads. A larger competitor wants in. The word on the table is “merger,” and it sounds clean, almost gentle, like two rivers joining.
Then the advisers arrive, and that single word splinters into a menu. Merger, acquisition, amalgamation, or a slump sale of just the profitable die-casting division? Each is a different type of M&A, and each carries its own legal machine, its own approval clock, and its own tax bill.
That’s the moment most people discover that “mergers and acquisitions” isn’t one thing. It’s a family of deal structures that happen to share a headline. Choose a statutory merger and you’re heading to the National Company Law Tribunal (NCLT) for a court-supervised scheme that can run six to twelve months.
Choose a share acquisition and you might close in weeks, though you inherit every liability the target ever signed. Choose a slump sale and you can hive off one division for a lump sum, but the capital-gains math changes entirely.
The promoter in Pune learned this the way most founders do: expensively, and in the middle of a live negotiation. The buyer’s counsel proposed a slump sale of the die-casting unit, which sounded like a tidy carve-out. What it also meant was that the accumulated tax losses sitting in the parent couldn’t simply travel with the unit, and the gain would be taxed as capital gains under a specific section of the Income-tax Act.
Restructure the same deal as an amalgamation, and those losses might have carried forward, subject to conditions. Same business, same buyer, same number on the cover page. A crore or more of difference underneath.
Here’s the thing that separates the people who get paid well in this field from the people who watch from the sidelines. The structure is the deal. A junior analyst in a Bengaluru investment bank, a company-secretary aspirant in Delhi, a founder in a tier-2 town, or a commerce graduate eyeing a corporate-law seat all need the same foundation: a clear map of what each type of M&A is, how it works, and what it costs.
And the professionals who carry that map in their heads are the ones a deal team wants in the room. They can read a term sheet and say, in a sentence, why a merger beats a slump sale for this target, or why a hostile bid for a listed company will trip the open-offer rules. That fluency is learnable. It starts with getting the taxonomy straight, which is exactly what this guide does.
The Indian layer matters here, and it shifted recently. From 1 April 2026, the Income-tax Act, 2025 replaced the old 1961 Act and renumbered the very provisions that govern slump sales and amalgamations. Get those numbers right and you already sound sharper than most of the guidance still floating around online.
The main types of M&A are mergers, acquisitions, amalgamations, slump sales, and demergers. They differ in how the businesses combine, whether the original companies survive, how the deal is approved (an NCLT scheme, a share transfer, or an asset transfer), and how it’s taxed under India’s Income-tax Act, 2025 and the Companies Act, 2013.
Each structure below is broken down the same way: what it is, how it works in practice, what it triggers under Indian law, and how it’s taxed. Use the table of contents to jump straight to merger, acquisition, amalgamation, slump sale, or the side-by-side comparison.
What M&A means, and why the structure changes everything
Why does the label matter so much when the business outcome looks identical? Because in M&A, the structure you pick decides which law governs the deal, who has to approve it, how long it takes, and what the tax authority collects at the end. Two deals that both “combine two companies” can sit under completely different statutes and produce tax bills that differ by crores.
The name is not cosmetic. And it’s the operating system of the transaction.
M&A as an umbrella term
Mergers and acquisitions is a catch-all for transactions that change the ownership or control of a business. Under the umbrella sit several distinct structures: a merger (two or more companies fusing into one), an acquisition or takeover (one company buying control of another), an amalgamation (a specific statutory fusion), a slump sale (selling an entire undertaking for a lump sum), and a demerger (splitting one company into more). People use “merger” loosely to mean any of these. Practitioners don’t, because the differences decide the paperwork.
The cleanest way to hold the taxonomy in your head is to see two axes. The first axis is how the businesses combine: do the companies fuse into a single legal entity, or does one simply take control of the other while both keep existing? The second axis is how the deal is legally structured: as a court-approved scheme, a purchase of shares, or a transfer of assets or an entire undertaking. Nearly every M&A structure is a combination of a point on each axis.
Why the classification decides everything downstream
Get the axis-reading right and the rest follows. A statutory merger or amalgamation runs through a scheme sanctioned by the NCLT under Sections 230 to 232 of the Companies Act, 2013. A share acquisition is governed by a share purchase agreement and, for a listed target, the SEBI takeover rules.
A slump sale is a transfer of an undertaking taxed under the Income-tax Act. Same commercial goal, three different rulebooks.
In practice, the mistake we see most often is a founder or a first-year analyst treating “merger” and “acquisition” as interchangeable words for the same event. They aren’t. In a merger, at least one company ceases to exist and its business vests in another.
In an acquisition, the target usually survives as a subsidiary of the buyer. That single distinction changes the approvals, the accounting, and the way liabilities pass. The professionals who master the full M&A deal process treat the structure decision as the first real decision of any deal, not an afterthought.
A question that comes up constantly in corporate-law and CA study groups is why India needs a tribunal involved at all when two private companies just want to combine. The short answer is creditor and shareholder protection. A merger reshuffles who owns what and who is owed what, so the law inserts a supervised process with notice, voting thresholds, and objections before the combination becomes final. That supervision is also why the structure you choose affects the timeline so heavily.
Worth flagging: this supervisory role used to sit with the High Courts. Until the Companies Act, 2013 machinery came into force, merger and amalgamation schemes were sanctioned by the relevant High Court. Jurisdiction shifted to the NCLT when the tribunal provisions were notified in the mid-2010s, which is why older case law still refers to Sections 391 to 394 of the Companies Act, 1956, the predecessors of today’s Sections 230 to 232. If you read a judgment that cites the old sections, it’s describing the same scheme process under the earlier numbering.
Types of M&A at a glance
Before the deep dives, it helps to see the whole family on one page. Which structure fuses the companies? Which one keeps them separate?
Which is taxed as a transfer, and which can be tax-neutral? The table below is the map; the sections after it are the territory.
Think of it this way. Mergers and amalgamations sit on the “fuse into one entity” side and usually run through an NCLT scheme. Acquisitions sit on the “take control, keep separate” side and run through a contract.
Slump sales and demergers are about moving a business unit rather than the whole company. Once you can place any deal you read about into one of those buckets, the rest of the analysis gets much easier.
| Type | What it is | Do the original companies survive? | Primary legal route (India) | Typical tax character |
|---|---|---|---|---|
| Merger | Two or more companies fuse into one | At least one ceases to exist | NCLT scheme, Companies Act 2013 Ss. 230 to 232 | Tax-neutral if conditions met |
| Amalgamation | A statutory merger meeting Income-tax Act conditions | Amalgamating company dissolves into the amalgamated one | NCLT scheme + Income-tax Act definition | Tax-neutral if conditions met |
| Acquisition (takeover) | One company acquires control of another | Both usually survive (target becomes a subsidiary) | Share purchase agreement; SEBI SAST for listed targets | Capital gains for the selling shareholders |
| Slump sale | An entire undertaking sold for a lump sum | Both survive; only the unit moves | Business transfer agreement, Income-tax Act S. 77 | Capital gains on the undertaking |
| Demerger | A company splits off one or more undertakings | Both survive (demerged + resulting company) | NCLT scheme; Income-tax Act definition | Tax-neutral if conditions met |
The practical reality is that a single real-world deal often blends these. A buyer might acquire a company’s shares (an acquisition) and later fold that subsidiary into itself (an amalgamation), or carve out one division by demerger before selling it by slump sale. A common question in finance forums is whether an “acquisition” and a “takeover” are different things.
They’re the same event described with different emotional temperature: “takeover” usually signals that the target’s board resisted, which we’ll get to under hostile deals. The rest of this guide takes each structure in turn, starting with the one everyone thinks they already understand.

Merger: meaning and the six economic types
Everyone says “merger,” but few can define it precisely, and that gap costs marks in exams and credibility in meetings. So what separates a real merger from the loose way people use the word? A merger is a statutory fusion: two or more companies combine so that their assets, liabilities, and businesses vest in a single surviving entity, and at least one of the original companies ceases to exist.
It isn’t a handshake or a joint venture. It’s a court-supervised change in legal existence.
What legally happens in a merger
In India, a merger is given effect through a scheme of arrangement sanctioned by the NCLT under Sections 230 to 232 of the Companies Act, 2013. The companies draw up a scheme, obtain approval from shareholders and creditors (broadly a three-fourths majority in value of those voting), and the tribunal sanctions it after hearing objections. Once the order takes effect, the transferor company’s undertaking passes to the transferee by operation of law, and the transferor is dissolved without winding up. No asset-by-asset conveyance is needed, which is one reason a merger can be cleaner than buying assets one at a time.
Mergers split into two structural forms. In a merger by absorption, an existing company absorbs one or more others, and the absorbing company survives (think a large company swallowing a smaller one). In a merger by consolidation, two or more companies combine to form an entirely new company, and all the combining companies dissolve into it. But the choice affects branding, licences, and which entity’s registrations continue.
The six economic types of merger
Now, here’s where it gets interesting. Beyond the legal form, mergers are classified by the economic relationship between the businesses. This is the classification examiners love and the one that tells you why a deal is happening.
- Horizontal merger: two competitors in the same industry and stage combine, for example two cement makers. The goal is market share and scale, and this type draws the closest scrutiny from competition regulators.
- Vertical merger: a company merges with a supplier or a customer along its supply chain, for example a car maker merging with a components supplier. The goal is control over inputs or distribution.
- Conglomerate merger: two companies in unrelated businesses combine, for example an FMCG group merging with a financial-services firm. The goal is diversification.
- Market-extension merger: two companies selling the same products in different geographies combine to widen their market reach.
- Product-extension merger: two companies selling related but non-competing products to the same customers combine, adding to each other’s product line.
- Congeneric (concentric) merger: two companies in the same broad industry but with different products or technologies combine, sharing customers or channels without being direct rivals.
Here’s what that looks like on the ground. When two mid-sized IT-services firms in Bengaluru combine to bid for larger US contracts, that’s a horizontal merger aimed at scale. When a Gujarat textile manufacturer merges with the trading company that exports its fabric, that’s a vertical merger aimed at capturing margin along the chain. The economic label predicts the regulatory attention: horizontal deals between real competitors are the ones most likely to draw a hard look from the Competition Commission of India.
In practice, the type of merger also shapes the integration risk. What experienced dealmakers know is that conglomerate mergers, the diversification plays, have the weakest track record of creating value, because the acquirer often lacks the operating knowledge to run a business far from its core. A common question from students is whether a “merger of equals” is a distinct legal type.
It isn’t. It’s a public-relations framing for a merger where the two companies are of similar size; the statutory process is identical to any other merger.
The pitfall to avoid is assuming a merger is always the fastest route. It rarely is. Because it needs an NCLT scheme, a merger typically takes longer than a straightforward share acquisition, which can close on a contract without a tribunal. If speed is the priority and the goal is control rather than fusion, an acquisition may serve better, which brings us to the next structure.
Acquisition (takeover): share purchase, asset purchase, friendly and hostile
An acquisition answers a different question from a merger: not “how do two companies become one?” but “how does one company take control of another?” In an acquisition, the buyer purchases enough of a target to control it, and the target typically keeps existing as a separate legal entity, now a subsidiary. Nothing dissolves. And control simply changes hands.
Share acquisition versus asset acquisition
There are two fundamental ways to acquire a business, and the fork matters more than beginners realise. In a share acquisition (a share purchase), the buyer acquires the target’s shares and, with them, the whole company: its assets, its contracts, its licences, and crucially its liabilities, known and unknown. In an asset acquisition (an asset purchase or business purchase), the buyer cherry-picks specific assets and agreed liabilities, leaving the rest behind in the seller’s hands.
Which is better? It depends on which side you sit. In practice, though, buyers often prefer asset deals because they can leave unwanted liabilities behind, for example a pending lawsuit or a tax exposure.
Sellers often prefer share deals because they exit cleanly and the tax treatment can be simpler. The tension between those preferences is negotiated in every deal, and the resolution usually turns on the target’s liability profile and the relative bargaining power of the two sides.
An asset acquisition of an entire undertaking for a single lump-sum price, without assigning values to individual assets, is a special case with its own tax code: the slump sale, covered in its own section below. When a buyer instead picks assets individually with a price against each, that’s an itemised asset sale, taxed asset by asset. The distinction is subtle and it changes the tax outcome, so it’s worth holding on to.
Friendly versus hostile, and the listed-company rules
Acquisitions also divide by the target board’s attitude. In a friendly acquisition, the target’s board recommends the deal to its shareholders. In a hostile takeover, the acquirer goes around a resisting board, usually by buying shares in the open market or making an offer directly to shareholders. Hostile bids are far more common in the world of listed companies, where shares are freely tradable, than in closely held private ones, where the promoters control the register.
In practice, for listed Indian companies, acquisitions run into a specific rulebook: the SEBI (Substantial Acquisition of Shares and Takeovers) Regulations, 2011, known as the Takeover Code. The headline trigger is the 25% threshold: an acquirer crossing 25% of the voting rights in a listed company must make an open offer to buy at least another 26% from public shareholders. And the rule exists so that when control changes, ordinary investors get a chance to exit at a fair price rather than being trapped under a new controller they didn’t choose.
Here’s what that looks like in a real scenario. A mid-cap listed manufacturer becomes a target when a rival quietly accumulates its shares. The moment the rival’s holding crosses 25%, the Takeover Code compels a mandatory open offer, which turns a cheap creeping acquisition into an expensive, public, regulated one.
That’s the code doing its job. A frequent question on investing forums is whether every purchase of a listed company’s shares triggers an open offer. It doesn’t: the obligation bites only when you cross the specified thresholds for shares or control, which is why acquirers structure their buying carefully around those lines.
The pitfall here is a private-company buyer assuming the listed-company rules apply to them, or vice versa. They’re different worlds. A share acquisition of an unlisted private company is a matter of contract and Companies Act compliance, with no open-offer machinery. Misjudging which regime applies is one of the faster ways to derail a deal, and it’s a distinction the analysts who structure these deals are trained to spot on the first read.
Amalgamation: meaning and how it differs from a merger
If merger and amalgamation feel like the same word wearing two outfits, you’re not wrong to be confused: in everyday use they overlap heavily. The distinction is technical, and in India it’s mostly a tax distinction. So why does the law keep two separate words for what looks like a single event? Every amalgamation is a merger, but only a merger that satisfies specific conditions in the tax law earns the label “amalgamation” and, with it, tax-neutral treatment.
What amalgamation means in law
The word carries two layers. Under company law, an amalgamation is simply a merger effected through a scheme under Sections 230 to 232 of the Companies Act, 2013, where one or more companies combine into another. Under tax law, “amalgamation” is a defined term with teeth.
The definition in Section 2 of the Income-tax Act, 2025 (the provision that carried the number 2(1B) in the old 1961 Act) requires that all the property and all the liabilities of the amalgamating company pass to the amalgamated company, and that shareholders holding at least three-fourths in value of the shares in the amalgamating company become shareholders of the amalgamated company. Miss those conditions and the deal may still be a valid merger, but it loses the tax-neutrality that makes amalgamation attractive.
If you ask us, the difference between “merger” and “amalgamation” in the Indian context is largely this: merger is the general company-law event, and amalgamation is the merger that also clears the tax test. In an amalgamation, the amalgamating company (the one being absorbed) dissolves, and its business continues inside the amalgamated company. Like mergers, amalgamations come as amalgamation by absorption (into an existing company) or amalgamation by consolidation (into a newly formed one).
Amalgamation in the nature of merger versus purchase
There’s a second classification that trips up accounting students, and it comes from how the combination is recorded in the books. The older standard, Accounting Standard 14, split amalgamations into two kinds. An amalgamation in the nature of merger is a genuine pooling: the two businesses and their shareholders carry on together, assets and liabilities are recorded at existing book values, and there’s continuity. An amalgamation in the nature of purchase is closer to one company buying another, recorded at fair values, with any excess treated as goodwill.
For companies now reporting under Indian Accounting Standards, business combinations are dealt with under Ind AS 103, Business Combinations, which generally applies the acquisition method, while combinations of entities under common control follow a pooling-style approach. In practice, the point to remember is that whether an amalgamation is treated as a merger or a purchase changes the balance sheet, the goodwill, and the future depreciation, so the classification is not academic. It flows straight into reported profit.
A common question in CA and CS forums is whether “amalgamation” and “absorption” are different types. Here’s the clean way to hold it: absorption is a form of amalgamation (an existing company absorbs another), while consolidation is the form where a brand-new company is created. And the confusion is worth clearing early, because exam questions probe exactly this.
And the pitfall in real deals is assuming amalgamation is automatically tax-neutral. It isn’t. The three-fourths shareholder-continuity condition and the requirement that all assets and liabilities pass must be satisfied, or the tax neutrality evaporates.
Slump sale: selling an undertaking as a going concern
What if a company wants to sell just one division, not the whole business and not a random list of assets? That’s the problem the slump sale solves, and it’s one of the most heavily searched M&A structures in India because the tax treatment is so specific. A slump sale is the transfer of an entire undertaking as a going concern, for a single lump-sum price, without assigning values to the individual assets and liabilities inside it.
What qualifies as a slump sale
Here’s the thing: the defining feature is the lump sum. In a slump sale, the buyer and seller agree one price for the whole undertaking (the plant, the people, the contracts, the receivables, the works), and they deliberately do not break that price down asset by asset. And the undertaking must be transferred as a going concern, meaning it’s capable of running on its own after the transfer, not stripped for parts.
This is where most first-time sellers go wrong. The moment the parties start assigning separate values to individual assets, the deal drifts toward an itemised asset sale, which is taxed differently.
Under the Income-tax Act, 2025, the definition sits in Section 2 (the provision numbered 2(42C) in the old 1961 Act), and a 2021 amendment widened it so that a slump sale now covers the transfer of an undertaking by any means, not only by “sale.” That closed a long-running loophole where taxpayers argued that a slump exchange (swapping an undertaking for something other than cash) escaped the slump-sale rules. It doesn’t anymore.
How a slump sale is taxed
Here’s where the recent renumbering matters, and where you can sound current instead of dated. The computation now lives in Section 77 of the Income-tax Act, 2025, the provision that was Section 50B under the old 1961 Act. The mechanics are the same: the capital gain is the lump-sum consideration minus the “net worth” of the undertaking, where net worth is broadly the undertaking’s assets minus its liabilities as per the books (with some prescribed adjustments). What most people miss is that net worth stands in for cost of acquisition, since the parties never assigned individual asset values.
The holding period sets the character of the gain. If the undertaking was owned and held for more than 36 months before transfer, the gain is long-term; 36 months or less, and it’s short-term, which usually means a higher effective tax rate. There’s also a fair-value floor: rules introduced with the 2021 amendment require the consideration to be measured against the fair market value of the undertaking, so parties can’t understate the price to shrink the gain. In our view, this fair-value rule is the single most overlooked part of slump-sale planning, and it catches sellers who assume they can name any number they like.
Here’s what that looks like in practice. A software company in Hyderabad wants to sell its loss-making hardware division while keeping its core product business. Structured as a slump sale, the division moves as a going concern for one lump sum, the buyer takes on the unit’s employees and contracts intact, and the seller computes capital gains on consideration minus net worth.
A frequent question on tax forums is whether the seller can pick which liabilities to leave behind. In a true slump sale of a going concern, the undertaking transfers with its associated liabilities; strip too much out and you risk the deal being recharacterised as an itemised sale, with a very different tax bill. That recharacterisation risk is the classic slump-sale pitfall.
Demerger: splitting a company tax-efficiently
Not every restructuring is about combining. Sometimes the value move is the opposite: splitting one company into two so each part can be run, valued, or sold on its own. So what does it look like when a company deliberately splits itself apart? That’s a demerger, and it belongs in any honest list of M&A structures because it’s the mirror image of a merger and it’s frequently the first step before a sale.
What a demerger is
A demerger is the transfer of one or more undertakings from a company (the demerged company) to another company (the resulting company), usually through an NCLT-sanctioned scheme, with the resulting company’s shares going to the demerged company’s shareholders. In practice, the classic use case is a conglomerate separating two very different businesses, for example splitting a consumer-products arm from an infrastructure arm, so the market can value each on its own merits and each can pursue its own investors.
In practice, for a demerger to be tax-neutral, the Income-tax Act imposes conditions in its definition (the provision numbered 2(19AA) under the old 1961 Act): the undertaking must transfer as a going concern, the resulting company must issue its shares to the demerged company’s shareholders on a proportionate basis, shareholders holding at least three-fourths in value must continue, and the assets and liabilities must move at book value. But clear those conditions, and neither the company nor its shareholders faces an immediate capital-gains charge on the split. Worth flagging: under the current Act, tax-neutral treatment is tied to demergers carried out through the Sections 230 to 232 route, so a split done through certain fast-track mechanisms may not qualify for the same neutrality.
Demerger versus slump sale
Since both move a business unit out of a company, students constantly ask how a demerger differs from a slump sale. The short answer? The distinction is clean once you see it. A slump sale is a sale for consideration, typically cash, and it produces a taxable capital gain for the seller.
A demerger is a court-approved reorganisation where the resulting company’s shares go to the original shareholders, and if the conditions are met, it’s tax-neutral. One is a monetising exit; the other is a restructuring that keeps the same shareholders in the picture across two companies.
The mistake we see most often is treating the two as interchangeable routes to “carve out a division.” They aren’t. If the promoters want cash now, a slump sale delivers it but triggers tax. If they want to separate businesses while keeping ownership continuity and deferring tax, a demerger fits better but needs a scheme and takes longer. Choosing between them is a genuine strategy decision, not a formality, and it’s the kind of judgement that shows up in professional corporate finance advisory work every week.
Merger vs acquisition vs amalgamation vs slump sale: the differences that matter
By now the individual structures are clear, so let’s put the four that headline this guide side by side, because the exam questions and the client questions both come in comparison form. What separates a merger from an acquisition, an amalgamation from a merger, and a slump sale from all of them? Four dimensions do most of the work: entity survival, what changes hands, the approval route, and the tax character.
| Dimension | Merger | Acquisition | Amalgamation | Slump sale |
|---|---|---|---|---|
| What changes hands | Whole companies fuse | Controlling stake (shares) or assets | Whole companies fuse (tax-defined) | An entire undertaking, for a lump sum |
| Do the originals survive? | At least one dissolves | Both survive; target becomes a subsidiary | Amalgamating company dissolves | Both survive; only the unit moves |
| Approval route (India) | NCLT scheme, Companies Act Ss. 230 to 232 | Share purchase agreement; SEBI SAST if listed | NCLT scheme + Income-tax Act conditions | Business transfer agreement |
| Consideration | Usually shares of the surviving company | Cash, shares, or a mix | Usually shares of the amalgamated company | A single lump-sum price |
| Tax character | Tax-neutral if conditions met | Capital gains for selling shareholders | Tax-neutral if Income-tax Act conditions met | Capital gains under Section 77 |
Think of it this way: read across that table and the confusions resolve themselves. Merger and amalgamation are the closest pair: both fuse companies through an NCLT scheme, and the practical difference is that “amalgamation” is the tax law’s name for a merger that qualifies for tax neutrality. Acquisition is the odd one out on entity survival, because the target keeps existing as a subsidiary rather than dissolving. And slump sale is the odd one out on scope, because it moves a single undertaking rather than a whole company, for cash rather than shares.
The practical reality is that the choice between them is driven by three questions: does the buyer want the whole company or just a piece, does anyone need cash out today, and how much tax can the structure legally defer? Answer those and the right structure usually names itself. A frequent question is whether a slump sale can ever be “tax-free” like an amalgamation.
Not in the same way: a slump sale is a sale, so it produces a capital gain, whereas an amalgamation or demerger that meets its conditions defers the charge. That’s the core reason promoters reach for schemes rather than sales when tax efficiency is the priority.
| Dimension | Merger | Acquisition | Amalgamation | Slump sale |
|---|---|---|---|---|
| What changes hands | Whole companies fuse | Controlling stake or assets | Whole companies fuse (tax-defined) | An entire undertaking, for a lump sum |
| Originals survive? | At least one dissolves | Both survive; target is a subsidiary | Amalgamating company dissolves | Both survive; only the unit moves |
| Approval route (India) | NCLT scheme, Ss. 230 to 232 | Share purchase agreement; SEBI SAST if listed | NCLT scheme + Income-tax Act conditions | Business transfer agreement |
| Consideration | Shares of the surviving company | Cash, shares, or a mix | Shares of the amalgamated company | A single lump-sum price |
| Tax character | Tax-neutral if conditions met | Capital gains for selling shareholders | Tax-neutral if conditions met | Capital gains under S. 77 |
The legal and regulatory framework for M&A in India
Every structure above lands on the same regulatory terrain, and a deal that ignores it can be delayed, taxed punitively, or voided outright. So which authorities have to bless an Indian M&A deal, and when? Four regimes do most of the gatekeeping: company law and the NCLT, the tax statutes, the competition regulator, and (for listed targets) the securities regulator, with stamp duty and, in cross-border cases, foreign-exchange rules layered on top.
The company-law route: NCLT schemes and fast-track mergers
Mergers, amalgamations, and demergers structured as schemes run through the NCLT under Sections 230 to 232 of the Companies Act, 2013. The companies file the scheme, hold shareholder and creditor meetings (with the roughly three-fourths-by-value approval threshold), and the tribunal sanctions the scheme after notice to regulators and a hearing on objections. This is thorough, and it takes time: six to twelve months is a realistic range for the tribunal process alone. Worth flagging: that tribunal clock is the single biggest reason deals slip their announced timelines.
For simpler combinations, there’s a faster lane. Under Section 233 of the Companies Act, 2013, a fast-track merger lets certain companies (small companies, and a holding company with its wholly owned subsidiary, among others) merge without a full NCLT process, using approval by the Central Government through the Regional Director instead. It saves months.
The catch, as noted earlier, is that some tax-neutrality provisions are tied specifically to the Sections 230 to 232 route, so speed can come at a tax cost if the structure isn’t checked carefully. And cross-border mergers have their own gateway in Section 234, which permits mergers between Indian and foreign companies subject to RBI and other approvals.
Competition, securities, and the transaction taxes
Above a certain size, a deal needs clearance from the Competition Commission of India under the Competition Act, 2002. The CCI reviews “combinations” that cross prescribed asset or turnover thresholds to ensure they don’t harm competition, and its approval is suspensory, meaning the deal can’t close until the CCI clears it. India has also added a Deal Value Threshold, which brings large-value transactions (currently pegged at 2,000 crore rupees with substantial Indian operations) into the net even if the traditional asset and turnover tests aren’t met. In our view, that change matters most for technology and digital deals, where the target’s turnover can be small but the price enormous.
For listed targets, the SEBI Takeover Code adds the open-offer machinery discussed above, and any deal effected through a scheme attracts stamp duty. Stamp duty on an NCLT order sanctioning a scheme is charged as an instrument of transfer under the Indian Stamp Act, 1899, and because stamp duty is a State subject, the rate varies from State to State. Most substantial Indian deals therefore touch at least three of these regimes at once, and mapping them early is what separates a smooth closing from a stalled one.
What experienced practitioners know is that the regulatory sequence, not the price, is usually what sets the real timeline. And the sequence keeps evolving: the competition-law thresholds and the tax renumbering under the Income-tax Act, 2025 are both recent, so professionals expect the compliance map to keep shifting through 2026 and beyond.
A question that comes up constantly is whether every M&A deal needs CCI approval. It doesn’t. Small deals fall under the thresholds and, for genuinely small target businesses, a de minimis exemption can apply, so a modest acquisition of a small company usually proceeds without a CCI filing.
The pitfall is guessing. Getting the threshold analysis wrong and closing a notifiable deal without clearance (known as gun-jumping) can draw penalties, so the threshold check is one of the first things a deal team runs, not the last.
How each type of M&A is taxed in India
Ask any deal lawyer why a particular structure was chosen and the honest answer, nine times out of ten, is tax. In practice, tax is the reason promoters accept the delay of an NCLT scheme over the speed of a share sale, and it’s the reason a carve-out gets structured as a demerger rather than a slump sale. So where does each type land on the tax return?
Tax-neutral routes versus taxable ones
Here’s what that looks like on a tax return. The big divide runs between structures that defer tax and structures that trigger it. Amalgamations and demergers that meet their statutory conditions are treated as transactions not regarded as a “transfer” under Section 70 of the Income-tax Act, 2025 (the provision numbered Section 47 in the old 1961 Act).
No transfer means no immediate capital-gains charge, for the company or, in a qualifying demerger, for the shareholders. And that neutrality is the whole point of routing a combination through a scheme.
Slump sales sit on the other side of the line. The practical reality is that a slump sale is a sale, so it produces a capital gain, computed under Section 77 as consideration minus net worth, and taxed as long-term or short-term depending on the 36-month holding test. An itemised asset sale is more punishing still, because each asset is taxed on its own, which can mix short-term and long-term gains and even trigger different heads of income. Share acquisitions, meanwhile, are taxed in the hands of the selling shareholders as capital gains on their shares, not on the company.
| Structure | Tax on the company / undertaking | Governing provision (Income-tax Act, 2025) | Loss carry-forward available? |
|---|---|---|---|
| Amalgamation (qualifying) | Tax-neutral (not a “transfer”) | S. 70 (was S. 47) | Yes, subject to conditions (S. 116) |
| Demerger (qualifying) | Tax-neutral (not a “transfer”) | S. 70 (was S. 47) | Yes, for the transferred undertaking |
| Slump sale | Capital gains on the undertaking | S. 77 (was S. 50B) | No transfer of the seller’s losses to the buyer |
| Itemised asset sale | Capital gains asset by asset | Capital-gains provisions generally | No transfer of losses |
| Share acquisition | Capital gains for selling shareholders | Capital-gains provisions generally | Company’s losses stay put (subject to shareholding-continuity rules) |
The carry-forward of losses, and the knock-on effects
Here’s where the structure choice reaches further than most people expect. When a loss-making company amalgamates into a profitable one, its accumulated business losses and unabsorbed depreciation can carry forward and set off against the amalgamated company’s profits under Section 116 of the Income-tax Act, 2025 (the provision that was Section 72A in the 1961 Act), subject to conditions. Based on what we’ve seen, that single feature can be worth more than the operating synergies, which is why tax advisers model it early. Worth flagging: the Finance Act, 2025 tightened this, so accumulated losses now carry forward only for the balance of the period the amalgamating company itself could have used them, rather than resetting the clock for a fresh run.
Now, here’s the second-order effect that catches sellers off guard. Choose a slump sale to carve out a division and the parent keeps its accumulated tax losses, but those losses can’t be handed to the buyer with the undertaking; they stay stranded in a seller that may no longer have the profits to use them. Choose an amalgamation instead and the losses can travel, subject to Section 116.
Same carve-out, and a materially different after-tax result. This is exactly the crore-level swing the promoter in Pune ran into, and it’s why the tax analysis has to happen before the structure is fixed, not after. In our view, treating tax as a downstream compliance step rather than the first design input is the single most expensive mistake in Indian M&A.
| Structure | Tax on the company / undertaking | Provision (Income-tax Act, 2025) | Loss carry-forward? |
|---|---|---|---|
| Amalgamation (qualifying) | Tax-neutral (not a “transfer”) | S. 70 (was S. 47) | Yes, subject to S. 116 conditions |
| Demerger (qualifying) | Tax-neutral (not a “transfer”) | S. 70 (was S. 47) | Yes, for the transferred undertaking |
| Slump sale | Capital gains on the undertaking | S. 77 (was S. 50B) | Seller’s losses do not pass to the buyer |
| Itemised asset sale | Capital gains asset by asset | Capital-gains provisions | No transfer of losses |
| Share acquisition | Capital gains for selling shareholders | Capital-gains provisions | Company’s losses stay put, subject to continuity rules |
Choosing the right structure: when to use which
So, faced with a live deal, how do you pick? Let’s be honest, most people overcomplicate this. A handful of questions narrow the field fast, and once you’ve answered them the structure tends to select itself. The choice is rarely about elegance; it’s about matching the structure to what the parties genuinely need.
Think of it this way. Start with scope. Does the buyer want the entire company, or just a slice of it? For the whole company, the contest is between a merger or amalgamation (fusion, tax-neutral, slower) and a share acquisition (control, faster, inherits liabilities).
For just a slice, the contest is between a slump sale (cash out, taxable) and a demerger (ownership continuity, tax-neutral, needs a scheme). That first fork eliminates half the options. A smarter strategy is to settle scope before anyone argues about price.
Then layer in three more questions. Does anyone need cash today? If yes, lean toward a sale rather than a scheme. How clean is the target’s liability history?
If it’s messy, an asset or slump structure that leaves liabilities behind beats a share deal that inherits them. And how much tax is at stake in accumulated losses or capital gains? If the number is large, the tax-neutral scheme routes earn their extra months.
Here’s what that looks like in practice. Two family-owned group companies that want to consolidate, with no outside buyer and no need for cash, are a textbook amalgamation: fuse them through a scheme, carry the losses forward, defer the tax. A promoter who wants to sell one profitable division to a strategic buyer for cash is a textbook slump sale: one lump sum, capital gains under Section 77, done.
And a conglomerate whose two halves confuse the market is a textbook demerger: split them, keep the shareholders, let each half find its own valuation. Our recommendation: match the pattern to the need, and you’re most of the way there.
The mistake we see most often at this stage is letting the fastest structure win by default. The real question is not which structure is fastest. Speed is a real advantage, but a share acquisition that closes in three weeks and saddles the buyer with a hidden tax liability is not a bargain.
The better approach, in our view, is to let tax and liability drive the structure and treat timeline as a constraint to manage, not the goal to optimise. Reading a few real deals, such as the stages laid out in the full M&A deal process, builds the pattern recognition faster than any checklist.
Common mistakes and misconceptions about M&A types
Even sharp candidates and first-time founders trip on the same handful of misconceptions. Clearing them is worth a surprising number of marks and a fair bit of money. Fair warning: these misconceptions are exactly what trip candidates in vivas and interviews. So what does almost everyone get wrong?
The first is treating merger and amalgamation as entirely different animals. They’re not: an amalgamation is a merger that meets the tax law’s conditions. The second is believing all mergers are automatically tax-free.
Tax neutrality depends on satisfying specific conditions, including the three-fourths shareholder-continuity test; miss them and the deal is taxable. The third is thinking a slump sale means selling assets one by one. The opposite is true: a slump sale is precisely the deal where you don’t assign individual asset values, and the moment you do, it stops being a slump sale.
- “Takeover always means hostile.” A takeover is just an acquisition of control. Most are friendly, recommended by the target’s board; only a minority are the dramatic, board-resisted bids the word conjures.
- “A slump sale can be structured tax-free like an amalgamation.” No: a sale is a transfer, so it triggers capital gains under Section 77. Only qualifying amalgamations and demergers get the not-a-transfer treatment.
- “Every deal needs NCLT and CCI approval.” Schemes need the NCLT; contracts (share and asset deals) don’t. And CCI clearance is required only above the thresholds.
- “The buyer’s tax losses transfer in every deal.” They don’t. Losses travel in a qualifying amalgamation under conditions, but not in a slump sale or an ordinary asset purchase.
The deeper pitfall underneath all of these is sequencing: deciding the structure first and checking the tax and regulatory consequences afterward. Frankly, this gets it backwards. The consequences should drive the structure. Bottom line: get that order right, and most of the classic mistakes never get the chance to happen.
Frequently asked questions
What are the main types of M&A? The main types are mergers, acquisitions (takeovers), amalgamations, slump sales, and demergers. Mergers and amalgamations fuse companies into one; acquisitions transfer control while both companies survive; slump sales and demergers move a single business undertaking rather than the whole company. Each has its own legal route and tax treatment in India.
What is the difference between a merger and an acquisition? In a merger, two or more companies fuse into a single entity and at least one of the originals ceases to exist. In an acquisition, one company buys a controlling stake in another, and the target usually survives as a subsidiary. Mergers typically need an NCLT scheme; acquisitions can close on a contract.
What is the difference between a merger and an amalgamation? In Indian practice the difference is mainly a tax one. A merger is the general company-law fusion under the Companies Act, 2013, while an amalgamation is a merger that also satisfies the Income-tax Act’s conditions and therefore qualifies for tax-neutral treatment. Every amalgamation is a merger, but not every merger is an amalgamation.
Is amalgamation the same as absorption? Absorption is one form of amalgamation, where an existing company absorbs another. The other form is consolidation, where a brand-new company is created and the combining companies dissolve into it. So absorption and consolidation are two sub-types of amalgamation, not alternatives to it.
What is a slump sale in simple terms? A slump sale is the sale of an entire business undertaking as a going concern for a single lump-sum price, without assigning separate values to the individual assets and liabilities. It lets a company sell one division intact rather than the whole company or a random list of assets.
How is a slump sale taxed in India? A slump sale is taxed as capital gains under Section 77 of the Income-tax Act, 2025 (formerly Section 50B of the 1961 Act). The gain is the lump-sum consideration minus the undertaking’s net worth, and it’s long-term if the undertaking was held for more than 36 months, otherwise short-term.
What is the difference between a slump sale and an itemised asset sale? In a slump sale, one lump-sum price covers the whole undertaking and no values are assigned to individual assets. In an itemised asset sale, each asset carries its own price and is taxed separately. The distinction changes the tax computation, so parties define it carefully in the agreement.
What is the difference between a slump sale and a demerger? A slump sale is a sale for consideration (usually cash) that produces a taxable capital gain. A demerger is a court-approved split where the resulting company’s shares go to the original shareholders and, if conditions are met, it’s tax-neutral. One monetises the unit; the other reorganises it while keeping the same owners.
Is a merger tax-free in India? Not automatically. A merger structured as a qualifying amalgamation is tax-neutral, but only if it meets the Income-tax Act’s conditions, including that shareholders holding at least three-fourths in value of the amalgamating company continue as shareholders of the amalgamated company. But miss the conditions and the merger becomes taxable.
What are horizontal, vertical, and conglomerate mergers? A horizontal merger combines two competitors in the same industry; a vertical merger combines a company with its supplier or customer along the supply chain; a conglomerate merger combines two companies in unrelated businesses. The labels describe the economic relationship between the merging firms and predict the level of competition-regulator scrutiny.
What is a hostile takeover? A hostile takeover is an acquisition pursued against the wishes of the target company’s board, usually by buying shares in the open market or making an offer directly to shareholders. Hostile bids occur mainly with listed companies, where shares trade freely, and they trigger the SEBI Takeover Code’s open-offer rules once control thresholds are crossed.
What is the difference between a share purchase and an asset purchase? In a share purchase, the buyer acquires the target’s shares and inherits the whole company, including its liabilities. In an asset purchase, the buyer picks specific assets and agreed liabilities, leaving the rest behind. Buyers often prefer asset deals for liability protection; sellers often prefer share deals for a cleaner exit.
Which law governs mergers in India? Mergers and amalgamations are governed by the Companies Act, 2013 (Sections 230 to 232), and sanctioned by the National Company Law Tribunal. Tax treatment is governed by the Income-tax Act, 2025, competition clearance by the Competition Act, 2002, and, for listed companies, the SEBI Takeover Code.
What is a fast-track merger? A fast-track merger under Section 233 of the Companies Act, 2013 lets certain companies (such as small companies and a holding company with its wholly owned subsidiary) merge without a full NCLT process, using Central Government approval through the Regional Director. It’s faster, though some tax-neutrality provisions are tied to the standard scheme route.
Do all M&A deals need CCI approval? No. Only deals that cross the Competition Commission of India’s asset or turnover thresholds, or the Deal Value Threshold, need CCI clearance. Smaller deals and those covered by a de minimis exemption proceed without a filing, though closing a notifiable deal without clearance can draw penalties.
What is amalgamation in the nature of merger versus purchase? This is an accounting distinction. An amalgamation in the nature of merger is a genuine pooling recorded at book values, with business and shareholder continuity. An amalgamation in the nature of purchase is closer to one company buying another, recorded at fair values with any excess as goodwill, which changes the balance sheet and future profit.
What is the SEBI open-offer trigger? Under the SEBI Takeover Code, an acquirer crossing 25% of the voting rights in a listed company must make an open offer to public shareholders to buy at least a further 26%. The rule gives ordinary investors a chance to exit at a fair price when control of their company changes hands.
Can a slump sale be structured to be tax-neutral? Not in the way an amalgamation or demerger can. Because a slump sale is a sale, it’s a transfer that produces a capital gain under Section 77. Promoters who want to defer tax on moving a business unit generally use a qualifying demerger rather than a slump sale.
