ESOP Treatment During an Acquisition: Vesting, Payout, Tax

An acquisition changes the ESOP conversation from a design question to a payout question. Employees who have spent years watching a vesting schedule tick forward now want to know what their options are worth, when they will see cash, and how much of it the government will take. The answer depends less on the ESOP scheme document than most founders assume, and more on how the acquisition itself is structured: whether it is a cash buyout of shares, a stock for stock swap, or a scheme of amalgamation. Each route produces a different tax outcome for the same underlying option grant. This article works through vesting acceleration, payout mechanics, and tax treatment across the deal structures Indian startups actually use, so founders and employees can read a term sheet and know what happens next.

What happens to ESOP shares when a company is acquired?

The outcome depends on the deal structure and the scheme’s acceleration clause. In a cash acquisition, vested ESOP shares are typically bought out at the deal price, taxed as capital gains over the FMV already taxed at exercise. Unvested options either lapse, continue on the original schedule with the acquirer, or accelerate under a double trigger clause if the employee is let go within the protection window (Section 67, Income Tax Act 2025, successor to Section 45 of the 1961 Act, and the ESOP scheme document).

How the acquisition structure decides the tax outcome

The single biggest variable in ESOP tax treatment during an acquisition is not the vesting schedule or the exercise price. It is the legal form of the transaction itself. Indian acquisitions of startups take three common forms, and each one treats an ESOP holder differently.

A cash acquisition (a share purchase agreement under which the acquirer buys out existing shareholders, including employees who have exercised options, for cash) triggers an immediate, taxable transfer. The employee’s shares are sold, a sale price is fixed, and capital gains tax is computed on the spread between that price and the FMV already taxed at exercise.

A share swap (the acquirer issues its own shares in exchange for target company shares) is taxed differently depending on whether it qualifies as a scheme of amalgamation under Section 2(6) of the Income Tax Act 2025 (successor to Section 2(1B) of the 1961 Act). If it qualifies, the exchange itself is not treated as a transfer under Section 70 of the 2025 Act (successor to Section 47), and tax is deferred until the employee eventually sells the acquirer’s shares.

A scheme of amalgamation approved by the National Company Law Tribunal (NCLT) under Sections 230 to 232 of the Companies Act 2013 is the formal route to the second outcome. It carries specific shareholding continuity conditions that determine whether the exemption survives.

Deal structure and ESOP tax outcome at a glance

Deal structure	What the employee receives	Is the transfer taxed immediately	Governing provision
Cash acquisition (share purchase)	Cash for vested shares	Yes, capital gains on sale price minus FMV at exercise	Section 67, Income Tax Act 2025 (successor to Section 45, 1961 Act)
Share swap qualifying as amalgamation	Shares in the acquiring company	No, tax deferred to eventual sale of new shares	Section 70, Income Tax Act 2025 (successor to Section 47, 1961 Act)
Share swap not qualifying as amalgamation	Shares in the acquiring company	Yes, treated as a taxable exchange at the time of swap	Section 67, Income Tax Act 2025 (successor to Section 45, 1961 Act)
Asset or business transfer (slump sale)	No direct ESOP payout; new employer, fresh scheme decision	Not applicable to the option itself	Section 77, Income Tax Act 2025 (successor to Section 50B, 1961 Act, at company level)

The practical point for a founder reading a term sheet: before promising employees a number, confirm which of these four rows the deal actually falls into. A letter of intent that describes the transaction loosely as an acquisition can still resolve into any of these structures once the definitive agreement is drafted, and the tax outcome for every option holder changes with it.

What happens to unvested options: single trigger versus double trigger acceleration

Unvested options are the harder problem, because there is no shareholding to sell yet. What happens to them is governed entirely by the acceleration clause in the ESOP scheme and the definitive agreement, not by tax law.

Single trigger acceleration vests all unvested options immediately on the change of control, regardless of what happens to the employee’s job afterward. This is rare in Indian startup ESOP schemes because acquirers dislike it: it hands departing or underperforming employees a fully vested stake on day one, with no retention benefit to the acquirer.

Double trigger acceleration is the market standard. It requires two events before unvested options accelerate: the change of control itself, and the employee’s termination without cause (or, in some schemes, a material change in role or location) within a defined protection window after closing, typically 12 to 18 months. If the employee stays through the window, options continue vesting on the original schedule, usually under the acquirer’s plan or a replacement grant of equivalent value.

Where the scheme is silent, the outcome is negotiated in the definitive agreement, and it is negotiated late, often after employees have already heard rumours of the deal. Founders who have not addressed acceleration in the scheme document lose leverage in this negotiation, because the acquirer can propose whatever treatment suits its retention plan, and the target has no contractual fallback to point to.

Acceleration clause comparison

Acceleration type	Trigger	Employee protection	Acquirer’s typical view
Single trigger	Change of control alone	Full, immediate	Resisted, since it removes retention leverage
Double trigger	Change of control plus termination without cause within window	Conditional on the second event	Market standard, generally accepted
No acceleration clause	Not applicable	None; options continue or are negotiated case by case	Favours acquirer; outcome set by definitive agreement

A related question that surfaces in almost every acquisition: what is the tax character of a cash payment made to an employee to cancel unvested options that would otherwise lapse? Some tribunals have taken the view that a one time payment for surrendering an option that never vested, with no employment nexus beyond the original grant, can be treated as a capital receipt rather than salary. This is a fact specific and unsettled position that depends heavily on how the cancellation is documented, and Treelife does not recommend structuring around it without a specific opinion, since the default position taken by most employers, and the safer one, is to treat any cash paid in connection with an ESOP grant as a perquisite subject to TDS under Section 392 of the Income Tax Act 2025.

How a cash buyout of ESOP shares is taxed

A cash buyout is the cleanest structure to compute, because both taxable events, the perquisite at exercise and the capital gain at sale, are already familiar to anyone who has read a standard ESOP tax explainer. What changes in an acquisition is the timing: both events can now happen in quick succession, sometimes in the same financial year, and the holding period from exercise to the acquisition closing date decides the tax rate.

Consider an employee who exercised 5,000 shares at an exercise price of ₹50 per share when FMV, certified by a Category I Merchant Banker under Rule 15(6) of the Income Tax Rules 2026 (successor to Rule 3(8) of the 1962 Rules, applicable to allotments from 01/04/2026; exercises before that date fall under the 1962 Rules), stood at ₹300 per share. The perquisite of ₹12.5 lakh (5,000 shares multiplied by ₹250 spread) was taxed as salary income in the year of exercise, with TDS deducted under Section 392 of the Income Tax Act 2025.

Eighteen months later, the company is acquired for ₹600 per share in cash. The capital gain is ₹250 per share (₹600 minus the ₹350 cost of acquisition, being the FMV at exercise), or ₹12.5 lakh in total. Because the holding period from exercise to the sale date is under 24 months, this gain is short term and taxed at the employee’s slab rate, potentially 30 percent plus applicable surcharge and cess, rather than the 12.5 percent long term rate that would apply after 24 months.

This 24 month gap is the single largest avoidable tax cost in acquisition planning for employees who exercised early. An employee who exercised the same shares three years before the acquisition, rather than eighteen months before, would pay 12.5 percent instead of roughly 31 to 39 percent on the same ₹12.5 lakh gain, a difference of approximately ₹2.3 to ₹3.4 lakh depending on the applicable surcharge slab. Founders negotiating deal timelines with an acquirer, where the closing date can sometimes be moved by a quarter without changing commercial terms, should treat the 24 month clock for their largest option holders as a real number worth checking before signing.

• The perquisite is computed once, at exercise, and is not recomputed at the acquisition
• The FMV used at exercise becomes the fixed cost of acquisition for the capital gains computation
• The acquisition price, not any earlier valuation, is the sale consideration
• The 24 month holding period runs from the exercise date, never from the grant or vesting date
• Employees who have not yet exercised vested options when the acquisition is announced face both taxable events compressed into the same transaction, since the acquirer’s offer effectively forces an exercise and sale together

Stamp duty on the ESOP share transfer

Income tax is not the only levy on the transaction. Every transfer of shares, including the transfer of ESOP shares to an acquirer, also attracts stamp duty under the Indian Stamp Act 1899, as amended by the Finance Act 2019 with effect from 01/07/2020. The rate depends on how the shares are held: a transfer of securities in dematerialised form on a delivery basis attracts stamp duty of 0.015 percent of the transaction value, while a transfer of physical share certificates attracts 0.25 percent, more than sixteen times higher. For a founder still holding ESOP shares in physical form because the company never completed dematerialisation before the acquisition, this difference is a real, avoidable cost across the whole employee pool, not only for the founder’s own holding.

Stamp duty on a delivery based transfer through a depository is collected by the depository at the time of transfer and is ordinarily borne by the buyer, meaning the acquirer bears this cost rather than the employee, though acquisition agreements sometimes shift this by contract. Employees should confirm, before signing any transfer instruction, whether the payout figure quoted to them is net of stamp duty or gross, since a founder relaying an acquirer’s indicative price without accounting for this can create a small but avoidable expectation gap at closing.

When a share swap or scheme of amalgamation keeps the transfer tax neutral

Not every acquisition pays employees in cash. Where the acquirer is itself a growth stage company raising its own funding, or where the transaction is structured as a merger for strategic reasons, employees may receive shares of the acquiring company instead. Whether this exchange is taxed immediately turns on a specific legal test.

Does an ESOP share swap in a merger attract capital gains tax?

It does not, if the merger is structured as a scheme of amalgamation that satisfies Section 2(6) of the Income Tax Act 2025: all property and liabilities of the target transfer to the acquirer, and shareholders holding at least three fourths in value of target shares become shareholders of the acquirer. If these conditions hold, Section 70 treats the share exchange as not a transfer, and capital gains tax is deferred until the employee sells the acquirer’s shares.

If the merger fails this test, most commonly because the shareholding continuity threshold is not met, or because the transaction is structured as a simple share swap agreement rather than an NCLT sanctioned scheme under Sections 230 to 232 of the Companies Act 2013, the exchange is treated as a taxable transfer at the time of the swap. The employee is deemed to have sold the target shares at their fair value on the swap date and is taxed on the resulting capital gain, even though no cash has changed hands. This is the scenario founders most often miss: employees can owe a real tax bill on paper gains from an all stock deal, with no liquidity event to fund it.

Two further points matter for the employee’s downstream position. First, where the exemption applies, the cost of acquisition and the holding period of the original target shares carry forward to the new acquirer shares, so the 24 month clock for the eventual sale is not reset by the swap. Second, if the acquirer is a foreign company, the share swap additionally requires compliance with the Foreign Exchange Management (Non-Debt Instruments) Rules 2019, as amended, and the exemption under Section 70 does not itself resolve any FEMA reporting obligation, which is a separate compliance track covered in the cross border section below.

A structural point that trips up companies running ESOPs through a trust: the three fourths shareholding continuity test under Section 2(6) looks at who becomes a shareholder of the amalgamated company, not who is the beneficial employee. Where an ESOP trust holds shares on behalf of employees, the trust is the shareholder of record, and if the trust itself does not receive shares in the amalgamated company on the same terms as other target shareholders, the continuity condition can fail on a technicality even though every individual employee beneficiary is treated identically to a direct shareholder. Companies running the trust route should have the scheme of amalgamation document explicitly address the trust’s status as a continuing shareholder before the NCLT filing, not after.

How escrow and holdback consideration is taxed

Acquisition agreements routinely hold back a portion of the purchase price, typically 10 to 20 percent, in an escrow account for 12 to 24 months to cover indemnity claims, working capital adjustments, or earn out conditions. For ESOP holders whose payout includes an escrow component, the tax timing question matters as much as the tax rate.

Is the escrow portion of an ESOP payout taxable upfront?

The Income Tax Department’s general position, consistent with the accrual principle under Section 5 of the Income Tax Act 2025, is that consideration becomes taxable when the right to receive it accrues, not necessarily when cash is received. Where the escrow amount is fixed and its release depends only on the passage of time (no further contingency), tax authorities have in several cases taken the view that the full consideration, including the escrowed portion, accrues and is taxable in the year of the transaction itself, since the entitlement is not genuinely contingent.

Where release from escrow is genuinely conditional (dependent on an indemnity claim not being made, or an earn out target not being met), the stronger position is that the escrowed amount is a contingent right, not taxable until the contingency resolves and the amount is actually released. This distinction is fact specific and is frequently litigated in M&A transactions generally, not only in the ESOP context, and employees receiving an escrow linked payout should not assume either position without reviewing the specific escrow release conditions in the definitive agreement.

A separate practical issue: TDS on escrowed consideration is typically deducted only when the escrow is released, since the acquirer or the escrow agent has no cash in hand to withhold against earlier. This creates a mismatch where the employee may be advised that tax has technically accrued before any TDS credit appears in Form 26AS. Employees in this position should retain the escrow release schedule and the definitive agreement’s indemnity clauses as documentation for their return, since a tax officer questioning the timing of the capital gain will look at exactly these documents.

Can the company deduct the ESOP payout as a business expense

Founders and CFOs closing an acquisition rarely stop to ask whether the cost of cashing out ESOP holders is itself tax deductible, but it is a real question with a settled answer for one category and an open one for another.

For the underlying ESOP discount (the amortised difference between FMV and exercise price recognised as compensation cost over the vesting period) the position is settled in the company’s favour. The Special Bench of the Income Tax Appellate Tribunal in Biocon Ltd. v. DCIT [2013] 35 taxmann.com 335 (Bangalore ITAT SB) held that the ESOP discount is an allowable revenue expenditure under Section 37(1) of the 1961 Act, not a contingent liability, since it represents ascertained compensation for employee services rendered during vesting. The Karnataka High Court affirmed this in CIT (LTU) v. Biocon Ltd. [2020] 121 taxmann.com 351, and the Delhi High Court followed the same reasoning in PVR Ltd. v. CIT and in Pr. CIT v. New Delhi Television Ltd., with the Bombay High Court reaching the same conclusion in Pr. CIT v. Bajaj Finance Ltd. This line of cases is now consistently applied by tribunals, including in decisions as recent as 2025, and gives a founder reasonable confidence that ESOP compensation cost booked in the ordinary course is deductible. For expenditure incurred from 01/04/2026 onward, the equivalent provision is Section 34 of the Income Tax Act 2025 (general conditions for allowable deductions), which carries the same wholly and exclusively test forward, so the Biocon line of reasoning should continue to apply with equal force under the new section.

What remains genuinely open, and fact dependent, is whether an additional cash payment made specifically to settle or accelerate options in connection with an acquisition, over and above the ordinary Ind AS 102 compensation cost already expensed, qualifies for the same treatment. The Revenue’s likely position is that a payment tied to a change of control event, rather than to continued employee service, sits closer to a capital cost of the acquisition than an ordinary business expense, particularly where the target’s shareholders (not the target company) fund the payout as part of purchase consideration. Founders and finance teams should treat this incremental acquisition related cost as a separate question from the ordinary ESOP expense line, and take a specific view with a tax advisor on how it is characterised before the return is filed for that year, rather than assuming the Biocon line of cases automatically extends to it.

How the acquirer accounts for replacement options under Ind AS 103

Where the acquirer issues its own replacement options to the target’s ESOP holders (common in a share swap or a scheme of amalgamation) the accounting question is separate from, and sits alongside, the tax question above, and it affects the acquirer’s own financial statements, not the employee’s tax return.

Under Ind AS 103 (Business Combinations), Appendix B, paragraphs B56 to B62, a replacement award the acquirer is obliged to issue is measured at its acquisition date market based value and then split into two pieces. The portion attributable to the service the employee had already rendered before the acquisition (precombination vesting) is included in the consideration transferred for the target, and increases the goodwill or purchase price allocation computation. The portion attributable to service the employee is still required to render after the acquisition (postcombination vesting) is excluded from consideration and instead recognised as a compensation expense in the acquirer’s post-combination profit and loss, spread over the remaining service period, exactly as a fresh ESOP grant would be.

This split matters commercially, not just technically. An acquirer that treats the entire replacement award as purchase consideration overstates goodwill and understates the compensation expense that will hit its post-acquisition P&L over the following one to three years, an error that surfaces at the acquirer’s own year end audit, sometimes months after the target’s deal team has moved on. Founders on the sell side who are also shareholders should not assume the replacement award’s headline value is what the acquirer is truly paying for the business; a meaningful part of it is future compensation cost the acquirer has simply not yet recognised.

Award type on acquisition	Consideration transferred (affects goodwill)	Post-combination compensation cost (affects acquirer P&L)
Vested options, no further service required	Full market based value	None
Unvested options, acquirer obliged to replace	Portion attributable to precombination vesting	Portion attributable to postcombination vesting
Unvested options, acquirer voluntarily replaces beyond any obligation	None (not part of consideration)	Full market based value of the replacement award

Who deducts TDS once the acquirer takes over

Ownership of the payroll relationship, not just ownership of shares, changes in most acquisitions, and TDS responsibility for the ESOP payout follows the entity that is legally the employer or the payer at the relevant taxable event, not necessarily the entity paying the cash.

TDS responsibility by scenario

Scenario	Who deducts TDS	Under which provision
Exercise happens before the acquisition closes	Target company (as employer at exercise)	Section 392, Income Tax Act 2025
Vested shares are bought out for cash, employee is a resident buying from a resident acquirer	No withholding obligation on the buyer; the employee self-assesses and pays advance tax on the capital gain	No TDS provision applies to a resident-to-resident transfer of shares as a capital asset
Vested shares are bought out for cash, employee is a non-resident (NRI or foreign national)	Acquirer (as buyer), who must deduct TDS on the entire sale consideration, not only the gain, unless the employee obtains a lower or nil deduction certificate	Section 393(2), Income Tax Act 2025 (successor to Section 195, 1961 Act)
Unvested options accelerate and are cashed out as compensation	Whichever entity is the employer at the time of payment, most often the acquirer post closing	Section 392, treated as salary
Escrow release occurs after closing, employee has left	Escrow agent or acquirer, per the definitive agreement’s TDS mechanics clause; residency of the employee decides whether any TDS applies at all	Section 67 capital gains (resident) or Section 393(2) withholding (non-resident), as applicable

The practical failure Treelife sees most often at this stage: the definitive agreement is silent on which entity deducts TDS on the ESOP payout tranche, and both the target’s outgoing finance team and the acquirer’s incoming team assume the other side has handled it. This gap surfaces months later as a mismatch between the employee’s Form 16 or Form 130 and the actual credit reflected in Form 26AS, at which point reconciling it requires cooperation from an acquirer who has no ongoing relationship with the affected employee. Building an explicit TDS responsibility clause into the ESOP payout schedule of the definitive agreement, naming the deducting entity for each tranche, closes this gap before it opens.

Cross border acquisitions: FEMA and withholding considerations

When the acquirer is a foreign company, two additional compliance layers apply on top of the income tax treatment described above.

FEMA compliance on the share transfer. Any transfer of shares by a resident Indian ESOP holder to a non-resident acquirer must comply with the Foreign Exchange Management (Non-Debt Instruments) Rules 2019, as amended, including sectoral pricing guidelines and the requirement to file Form FC-TRS with the Authorised Dealer bank within 60 days of the transfer. This applies whether the transaction is a cash buyout or a share swap, and it applies at the level of each individual employee shareholder, not only at the level of the promoter or investor block being acquired. A company running an acquisition with 40 or 50 ESOP holders needs an FC-TRS filing process for each of them, and this is frequently underestimated in deal timelines.

Withholding on the compensation leg when the acquirer has no Indian TAN. Capital gains paid to a resident employee carry no TDS obligation regardless of whether the buyer is Indian or foreign, as the table above shows. The real cross-border withholding problem sits on the salary side: where unvested options are cashed out as compensation, or where the foreign acquirer becomes the employer of record post-closing, the obligation to deduct TDS under Section 392 attaches to whichever entity is the employer at the time of payment, irrespective of the employee’s residency. A foreign acquirer stepping into that employer role for the first time in India often has no Tax Deduction Account Number (TAN) and no payroll TDS process on day one. Structuring the compensation tranche to route through the Indian target entity, which already has a TAN and an existing payroll TDS process, is common practice specifically to avoid a gap between closing and the acquirer’s own India compliance infrastructure coming online. Founders negotiating deal mechanics should raise this early, since setting up a TAN and a payroll TDS process for a foreign acquirer after the definitive agreement is signed adds weeks to the payout timeline.

NRI and non-resident employees on the target’s cap table face a further layer: the character of their gain (perquisite versus capital gains) is taxed identically to a resident employee under Indian law if the underlying services were rendered in India, but they may separately owe tax in their country of residence, with relief available through the Double Taxation Avoidance Agreement (DTAA) and Form 67, where applicable, for foreign tax credit claims.

Common mistakes that cost employees and founders money

Assuming the ESOP scheme’s standard exit language covers an acquisition. Most schemes are drafted with company buybacks and secondary sales in mind. Acquisition specific language, particularly on acceleration and TDS responsibility, is often missing entirely, leaving the definitive agreement to fill the gap under time pressure.

Exercising options in the same window as the acquisition announcement. This compresses the perquisite and capital gains events into a single financial year and almost guarantees short term capital gains treatment on the sale leg. Employees who can exercise earlier, once a potential exit is on the horizon but before it is announced, materially improve their tax position, subject to having the cash to fund the exercise and the perquisite TDS.

Treating an all stock deal as tax free by default. Founders sometimes tell employees that a stock swap merger means no tax is due, without confirming the transaction actually meets the Section 2(6) amalgamation test. If it does not, employees face a real tax bill funded by illiquid shares, a worse outcome than a cash deal where at least the tax and the cash arrive together.

Leaving TDS responsibility unaddressed in the definitive agreement. As covered above, this creates reconciliation problems that surface long after the deal has closed and the target’s original finance team has moved on.

Ignoring FEMA filings for a foreign acquirer because the deal “is really a domestic secondary.” Any non-resident acquirer, however the deal is described commercially, triggers FC-TRS obligations at the individual shareholder level, and missing this filing exposes the company and the employee to compounding proceedings before the Reserve Bank of India.

Treelife’s ESOP scheme design guide covers how these acceleration clauses should be drafted before an acquisition is even on the table. Read the ESOP scheme design guide for the drafting side of this problem.

What Treelife has seen in live acquisition engagements

In the acquisition engagements we have run at Treelife, the most expensive surprises never come from the headline tax rate. They come from timing gaps that nobody owned. A recent mandate involved a Bangalore SaaS company being acquired by a US strategic buyer in a mixed cash and stock deal. The ESOP scheme had a double trigger clause, correctly drafted, but the definitive agreement’s TDS mechanics section was left blank pending “operational finalisation,” which in practice meant nobody decided who would deduct tax on the 60 percent cash tranche paid directly by the US acquirer, a foreign entity with no Indian TAN. We flagged this at the term sheet stage, before signing, and the parties agreed to route the cash tranche through the Indian target’s account specifically to preserve a domestic TDS deduction path under Section 392. Employees received their Form 16 entries correctly at year end, and the acquirer avoided a compounding exposure under FEMA for withholding it was not equipped to handle directly. The pattern only someone running live transactions would recognise: a well drafted ESOP scheme does not protect employees if the definitive agreement’s payment mechanics section is treated as boilerplate. That section is where the actual tax risk sits in a cross border deal.

Founders drafting or renegotiating an ESOP scheme ahead of a fundraise or exit should read Treelife’s guide on ESOP scheme design in Indian startup tax before the acquisition conversation starts, since acceleration and TDS clauses are far easier to negotiate before a deal is on the table than during one.

Case Study

Situation: Series C fintech company based in Bangalore, being acquired by a listed Indian financial services group in a cash and earn out structure.

Challenge: 45 ESOP holders across three grant years, no acceleration clause in the original scheme, an 18 month earn out tranche of 20 percent of consideration, and no agreed TDS mechanics for the earn out leg.

What Treelife did: Negotiated a double trigger acceleration addendum into the definitive agreement for the remaining unvested pool, structured the earn out tranche’s TDS deduction to sit with the target entity at release rather than the acquirer, and ran FC-TRS filings for the four NRI employees on the cap table within the 60 day window.

Outcome: Zero TDS mismatches at year end reconciliation, and the earn out tranche’s tax treatment was agreed and documented before closing, avoiding a dispute that the acquirer’s counsel had flagged as a risk in an earlier draft.

FAQs on ESOP treatment during an acquisition

Q: Is a cash buyout of ESOP shares taxed as salary or as capital gains?
A: Only the original exercise event is taxed as salary (the perquisite). The buyout itself, being a sale of already allotted shares, is taxed as capital gains under Section 67 of the Income Tax Act 2025 (successor to Section 45, 1961 Act), computed as the buyout price minus the FMV at exercise.

Q: What is the standard advisory fee structure for ESOP acquisition support?
A: Treelife structures ESOP acquisition support as a fixed scoped fee covering scheme review, acceleration negotiation, and TDS mechanics drafting, with FEMA filings for non-resident holders billed separately per filing. Exact fees depend on the number of option holders and deal complexity.

Q: How long does ESOP related work typically take once a definitive agreement is signed?
A: Scheme and acceleration review can be completed in one to two weeks if started at term sheet stage. FC-TRS filings for non-resident shareholders must be completed within 60 days of each transfer, and TDS reconciliation typically runs through the following assessment year’s return filing.

Q: What documents does an employee need to compute tax on an acquisition payout?
A: The exercise date FMV certificate, the exercise price paid, the definitive agreement’s payout schedule for that employee’s tranche, the escrow release schedule if applicable, and Form 16 or Form 130 reflecting TDS already deducted at exercise.

Q: Does a share swap acquisition require any FEMA filing if both companies are Indian?
A: No FEMA filing is required where both the target and the acquirer are Indian companies and no non-resident is involved in the specific share transfer. FEMA applies only where a non-resident is a party to the transfer.

Q: Can a founder change the ESOP scheme’s acceleration clause after an acquisition offer has been received?
A: Yes, subject to shareholder approval by special resolution under the Companies Act 2013, but doing so under active deal pressure, with employees aware a transaction is imminent, invites disputes over fairness. Amending the clause well before any acquisition conversation is the safer sequence.

Q: What happens to ESOPs granted to a promoter under the DPIIT exception if the company is acquired?
A: The same deal structure rules apply. A promoter’s options, whether vested or unvested, follow the acceleration clause and are taxed under the same perquisite and capital gains framework as any other employee’s options, since the DPIIT exception only affects eligibility to receive the grant, not its tax treatment on exit.

Q: Is the DPIIT perquisite tax deferral still available if the company is acquired before the deferral window ends?
A: No. Under Section 392(3) read with Section 289(3) of the Income Tax Act 2025, the deferral ends on sale of the shares, which an acquisition triggers. Deferred tax becomes payable within the statutory period following the acquisition.

Q: What happens if the employee has already resigned before the acquisition closes?
A: A resigned employee typically retains only vested and exercised shares, taxed exactly as any other seller in the deal, unless the scheme provides a specific post separation exercise window that is still open at the time of the acquisition, in which case the standard resignation exercise rules apply first.

Q: Does an ESOP trust structure change the tax treatment during an acquisition?
A: The tax treatment at the employee level is unchanged. What changes is the mechanics: the trust, as the registered shareholder, executes the sale or swap on behalf of employees, and the trust deed’s provisions on distribution timing can affect when each employee actually receives proceeds, which in turn affects TDS timing.

Q: What happens to options granted to an employee of a subsidiary being carved out and sold separately?
A: This is treated as a slump sale or business transfer at the company level, and the ESOP treatment depends on whether the employee transfers to the buyer’s employment. If employment transfers, the acquiring entity typically issues a replacement grant or honours acceleration under the original scheme; if the employee is terminated as part of the carve out, standard double trigger rules, where present, apply.

Q: Can the acquirer refuse to honour unvested options at all?
A: If the ESOP scheme has no acceleration clause and the definitive agreement is silent, the acquirer can propose cancellation of unvested options, sometimes with a cash payment in lieu, sometimes with none. This is a negotiated outcome, not a statutory entitlement, which is why the scheme document’s drafting before any deal matters.

Q: Is GST applicable on any part of an ESOP payout during an acquisition?
A: No. ESOP payouts, whether structured as perquisite income or capital gains, fall outside the scope of GST, since the transaction is a transfer of securities and an employment linked payment, neither of which attracts GST under the CGST Act 2017.

Q: Who pays the stamp duty on the transfer of ESOP shares to an acquirer?
A: Stamp duty on a delivery based transfer through a depository, at 0.015 percent of transaction value, is collected from and ordinarily borne by the buyer under the Indian Stamp Act 1899 as amended, unless the definitive agreement allocates it differently. Physical share transfers attract a materially higher 0.25 percent rate.

Q: Does an open offer apply to ESOP holders if the target is a listed company?
A: If the acquisition triggers an open offer under the SEBI (Substantial Acquisition of Shares and Takeovers) Regulations 2011, the open offer is made to public shareholders holding allotted shares, so an ESOP holder who has exercised and holds shares can tender into it. Unexercised vested options are not shares and cannot be tendered directly; the employee must exercise first, subject to the exercise window still being open.
