How Earnout Structures Actually Work in Indian Business Acquisitions

You and a seller can't agree on price. You think the business is worth ₹1.2 crore based on verified financials. The seller wants ₹1.8 crore based on where they believe the business is heading: a new client, a product launch, a growth story that hasn't shown up in the numbers yet. Both of you might be right. Neither of you can prove it yet.

An earnout is the tool built for exactly this disagreement: instead of settling on one number today, you agree to pay more later, if and when the business actually delivers what the seller is promising.

It's a useful, common structure, and in India, it comes with a tax question that genuinely isn't settled. Not "settled but complicated." Not settled at all, with two different lines of judicial reasoning that would tax the same transaction very differently. This guide explains how earnouts work, how to structure one, and exactly where that unresolved question sits so you don't get blindsided by it.

What Is an Earnout?

An earnout is a contractual provision in a business purchase agreement where part of the purchase price is deferred and paid to the seller only if the business hits specific, pre-agreed performance targets after the deal closes. The buyer pays a fixed amount at closing (the bulk of the price, typically) and additional tranches over a defined period, usually one to four years, contingent on the business achieving the agreed metrics.

The core idea is contingent consideration: instead of both sides guessing at a single number today, you let the business's actual future performance settle part of the price. If the seller's growth story is real, they get paid for it. If it doesn't materialize, the buyer isn't stuck having paid for a story that didn't come true.

Why Use an Earnout Instead of Just Negotiating Harder

Earnouts solve a specific negotiation problem, not a general one. They're not a substitute for doing your valuation homework; they're a tool for exactly one situation: a genuine, good-faith gap between what a buyer will pay based on verified numbers and what a seller believes the business is worth based on a trajectory that hasn't shown up in the numbers yet.

They're particularly useful when:

• The target has strong growth potential but lacks the track record to justify the seller's asking multiple on verified historicals alone
• The seller is staying on in an advisory or operating capacity post-close, and the buyer wants their continued success tied to their own payout
• A large customer contract, product launch, or expansion is pending and its outcome is genuinely uncertain to both sides

They're the wrong tool when the disagreement isn't really about future uncertainty but about one side simply refusing to accept what the current numbers show. An earnout can't fix a valuation dispute rooted in disagreement over historical facts; that's what due diligence and negotiation are for. It's built for disagreement about the future, not the present.

How Earnout Metrics Get Chosen, and Gamed

The metric you pick determines who bears risk, and each side has a natural preference for a reason:

This is also where earnouts most often go wrong. Once the seller no longer controls the business, the buyer controls the inputs that determine whether the earnout metric gets hit: how expenses get allocated, whether the buyer invests in growth or harvests cash, whether shared costs across a buyer's other businesses get charged disproportionately to the acquired unit. A revenue-based earnout is far harder for a buyer to manipulate than a profit-based one. If you're the seller and you're staying out of day-to-day control post-close, push hard for revenue or a clearly defined, externally verifiable non-financial milestone, not a profit number the buyer's own accounting choices can move.

Typical Earnout Terms in Indian SME Deals

There's no single standard in the Indian market the way there is, say, for stamp duty rates, but a few patterns show up consistently in practice:

• Earnout period: typically one to four years, with two to three years being the most common range for a straightforward SME deal (longer periods, and structures resembling ongoing royalties, are more common in specific sectors like mining or where a multi-year contract cycle is the natural measurement window)
• Earnout size relative to total price: varies enormously by deal, but earnouts function best as a genuine bridge. If the contingent portion is so large that the seller is effectively financing most of the purchase on a promise, it starts to look more like risk-shifting than price-bridging, and that changes how both sides should think about security and protections
• Caps: many earnouts are capped at a maximum payout regardless of how far the business exceeds targets; uncapped earnouts exist but are less common in SME deals and expose the buyer to open-ended liability if performance runs well ahead of plan
• Payment frequency: annual measurement and payment is typical; more frequent measurement adds administrative overhead that rarely justifies itself in an SME-scale deal

The Unresolved Tax Question

This is the part of earnout structuring that most generic deal-structure content skips, and it matters enough that it should shape how conservatively you draft the earnout clause.

The Income-tax Act, 1961 does not contain a specific provision addressing earnout taxation. That means the legal characterization has to be worked out from general principles and case law, and the case law doesn't point in one direction.

One line of reasoning, from the Bombay High Court in Commissioner of Income Tax v. Hemal Raju Shete: the full consideration is not treated as received in the year of transfer. Capital gains crystallize when each earnout tranche is actually paid, spread across the years the deferred consideration arrives: a taxpayer-friendly outcome, since you're taxed on money you've actually received, when you've received it.

A conflicting line of reasoning, from the Delhi High Court in Ajay Guliya v Assistant Commissioner of Income Tax, holds the opposite: that the full contingent consideration could be taxed in the year of transfer, regardless of whether the earnout is ever actually paid in full. If a business underperforms and the earnout never materializes, this reasoning offers no clean mechanism to recover tax already paid on income that was never received. That's a materially worse outcome for a seller, and it's not a hypothetical: it's a live doctrinal position from a High Court, not one that's been definitively closed off by a superior court.

There's a second layer of complexity on top of the timing question: whether an earnout payment is capital gains or ordinary income at all depends on what it's tied to. If it's genuinely tied to the business's post-acquisition performance with no strings to the seller's continued employment, the argument for capital gains treatment (taxed under Section 45) is strong. If the earnout is conditioned on the seller staying on and providing ongoing management or advisory services, tax authorities have a real basis to argue it's compensation for services, taxed as salary or business income under Sections 17 or 28, generally at a materially less favorable rate than capital gains.

What this means practically: if the seller is staying on post-close and the earnout partly rewards their continued involvement, structure the agreement to cleanly separate reasonable market-rate compensation for their ongoing services from the earnout itself, which should be tied strictly to the business's performance independent of who's running it. Blurring the two doesn't just create a negotiation problem; it hands the tax authority an argument to recharacterize the whole earnout as disguised salary.

Get a CA who specifically handles M&A tax structuring involved before the earnout clause is drafted, not after it's signed. This is not a place to rely on general startup-tax or personal-tax advice: the case law here is specific to M&A consideration and genuinely unsettled.

Where Earnouts Go Wrong: Disputes

The most common source of earnout litigation and breakdown, in India and everywhere else this structure is used, is disagreement over calculation, not disagreement over whether the earnout applies, but disagreement over whether the target was actually met.

Common failure points:

• The buyer changes how the business is run in ways that suppress the earnout metric: cutting marketing spend that would have driven revenue growth, reallocating shared costs onto the acquired business, delaying customer contracts into the next measurement period
• The seller, if still operating the business during the earnout period, over-indexes on hitting the metric at the expense of the business's actual long-term health: pulling forward revenue, deferring necessary costs, making decisions that look good on the earnout scoreboard and bad for the business a buyer will own long after the earnout period ends
• The purchase agreement doesn't clearly define how accounting matters get handled during the earnout period: what expenses count, how shared costs are allocated, whether the buyer can make acquisitions or changes that affect the metric

Every one of these is preventable with clear drafting at signing, and none of them are preventable after the fact. The earnout clause needs explicit operating covenants (what the buyer commits to doing or not doing during the earnout period), a clearly defined calculation methodology, and a dispute resolution mechanism, ideally a named independent accountant empowered to make a binding determination if the parties disagree on the number, rather than defaulting to litigation.

Earnouts vs. Seller Financing: Not the Same Tool

Worth being precise about this, because the two get conflated constantly. Seller financing is the seller lending the buyer part of the purchase price: a fixed amount, repaid on a fixed schedule with interest, regardless of how the business performs. An earnout is the opposite in one crucial respect: the amount owed isn't fixed at all; it depends entirely on the business hitting agreed targets, and could be zero.

They can be combined in the same deal, and often are (a seller-financed note for part of the price alongside an earnout for the disputed growth premium), but they solve different problems. Seller financing addresses a buyer's capital constraint. An earnout addresses a valuation disagreement about the future. If your actual problem is "the buyer doesn't have enough cash," seller financing or bank debt is the right tool. If your actual problem is "we disagree about whether this business is really worth what the seller thinks," an earnout is the right tool. Using an earnout to solve a pure capital-constraint problem, or seller financing to solve a pure valuation-disagreement problem, tends to produce a worse-structured deal than picking the tool that actually matches the problem.

How to Structure an Earnout Clause Properly

1. Pick a metric the seller can't easily dispute and the buyer can't easily manipulate. Revenue is usually cleaner than profit for exactly this reason, unless the buyer has strong justification for a profit-based structure.
2. Set operating covenants: explicit commitments on what the buyer will and won't do during the earnout period (minimum marketing spend, no forced cost reallocation from other business units, no material changes to pricing or customer terms without seller consultation if the seller has a real stake in the outcome).
3. Define the calculation methodology in detail: what counts as revenue or profit for earnout purposes, how shared costs are allocated if the buyer runs multiple businesses, when the measurement period starts and ends.
4. Cap the earnout unless there's a specific reason not to, and be explicit about what happens if targets are partially met: a cliff (all or nothing) or a sliding scale (proportional payout).
5. Separate any post-close employment or advisory arrangement from the earnout itself, with the employment terms priced at genuine market rate and documented independently. This is the single highest-leverage move for avoiding the compensation-recharacterization risk described above.
6. Build in a binding dispute resolution mechanism: typically a named independent accountant with authority to make a final determination on disputed calculations, avoiding a default to litigation.
7. Get CA sign-off on the tax structuring before signing, specifically addressing whether the earnout is being treated as deferred purchase consideration or could be recharacterized as compensation, and what that means for timing of tax liability given the current unsettled state of the law.

A Worked Example

A buyer and seller agree a base price of ₹1.5 crore for a services business with ₹40 lakh in verified annual profit, a roughly 3.75x multiple, already at the higher end of what verified numbers alone would typically support. The seller believes a recently signed but not-yet-delivered enterprise client will push annual profit to ₹55–60 lakh within 18 months, which would justify a higher price on its own, but that revenue hasn't shown up in any financial statement yet.

Structure: ₹1.2 crore paid at closing based on the ₹40 lakh verified profit at a conservative 3x multiple. An earnout of up to ₹45 lakh, paid over two annual tranches, tied to verified revenue from the named enterprise client specifically (not overall company revenue, which the buyer could otherwise inflate or suppress through unrelated business decisions), with a clearly defined calculation clause naming exactly which invoices count, a named independent accountant to resolve disputes, and no change to the seller's involvement in that specific client relationship without their consultation during the earnout period.

This structure lets the buyer avoid paying today for a client relationship that might not deliver, lets the seller capture the value if it does, ties the metric to something specific and hard for either side to manipulate, and avoids the compensation-recharacterization risk because there's no post-close employment or advisory arrangement tangled into the earnout at all.

The Bottom Line

Earnouts are a genuinely useful tool for a specific problem: a real disagreement about the future, not a dispute over the present. Used well, with a clean metric, clear operating covenants, and a defined dispute mechanism, they let deals close that would otherwise stall on price. Used carelessly, they create exactly the kind of ambiguity, over calculation, over control, and over tax treatment, that turns a bridge into a fight.

The tax question deserves particular respect here. This isn't a case where the answer is complicated but knowable with enough research; the case law genuinely points in two directions, and the right structure for your deal depends on specifics a general guide can't resolve for you. Treat the earnout clause as one of the most heavily lawyered and CA-reviewed parts of your purchase agreement, not a bolt-on at the end of negotiation.

If you're structuring a deal where price is the sticking point, getting the earnout mechanics right the first time is far cheaper than renegotiating a dispute two years into the earnout period. Talk to Kautilya PE about structuring a deal that actually survives its earnout period.
