ESOP taxation in India: the two taxing events

An Indian employee pays tax on stock options twice: as salary when they exercise and as capital gains when they sell. The first bill arrives before any cash does, unless the company qualifies for the start-up deferral.

An engineer exercises 4,000 options at ₹10 in a company a merchant banker values at ₹510 a share. She pays ₹40,000 for the shares and owes about ₹6 lakh of income tax on a gain she cannot sell. That bill, and not the exercise price, is why Indian employees leave vested options on the table, and it is the single thing about ESOPs a founder most needs to explain before anyone signs.

This lesson sets out the two taxing events in an Indian ESOP, the perquisite at exercise and the capital gain at sale, under the Income-tax Act 2025 that has been in force since 1 April 2026. It explains the deferral that eligible start-ups can offer their people, gives a figure that works one employee’s numbers through both events, and closes with what the company should do before every exercise window. How to size the pool and set the strike is a [separate lesson](/library/esop-design-pool-grants-strike-price).

An option is not income. The share is.

An option is a right to buy a share at a fixed price. Granting it creates no tax, and vesting creates none either: the employee owns nothing yet except the right. Tax arrives when the right turns into a share, because at that moment the employee holds something worth more than they paid for it, and the law treats the difference as part of what the employer paid them.

The Income-tax Act 2025 replaced the 1961 Act on 1 April 2026 without altering the underlying tax policy, so the mechanics a chartered accountant learned under the old numbers still hold. The perquisite from a specified security or sweat equity share now sits in section 17(1)(d) of the new Act, which the salary TDS section cross-refers to; under the old Act it was section 17(2)(vi). The start-up deferral is in section 392(3), read with section 140 for the definition of an eligible start-up. The Income Tax Department’s own explainer still uses the 1961 numbers and is the clearest statement of the rules.

Event one: exercise, taxed as salary

The perquisite is the fair market value of the share on the date of exercise, less the amount the employee paid. It is taxed as salary in the year of allotment, at the employee’s slab rate, and the employer deducts the tax through payroll in that month as it would on a bonus. The value on the date of allotment does not matter; the date of exercise does.

For a listed share, fair market value is the average of the opening and closing price on the exercise date on the exchange with the highest volume. For an unlisted share, it is the value a merchant banker determines as on the exercise date or a date not more than 180 days before it. That last rule is operational, not academic. A company that runs exercise windows needs a merchant banker’s report dated within 180 days of each window, so the board should commission one valuation and then schedule the windows inside its life.

Run the opening example. 4,000 shares at a fair market value of ₹510 less ₹10 paid is a perquisite of ₹20 lakh. At a 30 per cent slab, before surcharge and cess, the tax is ₹6 lakh. The employee’s salary for the month cannot carry ₹6 lakh of TDS, so the company either recovers it from the employee in cash or deducts it across the remaining months of the year. Either way the employee pays ₹6.4 lakh to own shares they cannot sell. For most employees in most private companies that is the end of the conversation.

The deferral for eligible startups

The Finance Act 2020 recognised the problem. It let an eligible start-up defer the deduction and the employee defer the payment until fourteen days after the earliest of three events: forty-eight months from the end of the assessment year of allotment, the employee ceasing to be employed by the company, or the sale of the shares. The tax is still computed at the rates of the year of allotment. The 2025 Act keeps the relief in section 392(3), with the employee’s payment date in section 289(3); confirm with the accountant how the new Act’s tax year changes the counting of the forty-eight months.

Eligible is narrower than recognised. The deferral is for an eligible start-up as the income-tax law defines it, which means a company or LLP that holds the Inter-Ministerial Board certificate under what was section 80-IAC: incorporated on or after 1 April 2016 and before 1 April 2030, recognised by DPIIT, and approved by the board on application. DPIIT recognition itself requires turnover below ₹200 crore and an age under ten years from incorporation, twenty for deep tech. Many recognised start-ups never apply for the IMB certificate because they have no profits to exempt. They should apply anyway if they have an ESOP, because the certificate is what unlocks the deferral for their employees.

The deferral postpones the bill. It does not shrink it. An employee who leaves in month eighteen owes the full tax fourteen days later, at the rates of the year of allotment, whether or not anyone has bought their shares. Explain that at the exit interview, in writing.

Event two: sale, taxed as capital gains

When the employee sells, the gain is a capital gain. Two rules from the department’s explainer do most of the work. The cost of acquisition is the fair market value on the date of exercise, the same figure taxed as salary, so nothing is taxed twice. And the holding period runs from the date of allotment to the date of transfer, not from the grant and not from vesting.

The rates are those the Finance (No. 2) Act 2024 set from 23 July 2024. There are two holding periods: twelve months for listed securities and twenty-four months for everything else, which includes shares of a private company. Long-term gains are taxed at 12.5 per cent on every class of asset, without indexation. Short-term gains on listed equity shares on which securities transaction tax was paid are taxed at 20 per cent; short-term gains on unlisted shares carry no special rate and are taxed at the seller’s normal rate. The first ₹1.25 lakh of long-term gains on listed equity in a year is exempt.

Finish the example. The engineer sells in a secondary sale thirty months after allotment at ₹900 a share. The gain is ₹390 a share above the ₹510 already taxed, ₹15.6 lakh in all, and because the unlisted shares were held more than twenty-four months it is long-term: ₹1.95 lakh at 12.5 per cent. Had the buyer come at month twenty, the same gain would have been short-term at her 30 per cent slab, ₹4.68 lakh. Four months of patience were worth ₹2.73 lakh. If the company were an eligible start-up, the ₹6 lakh from event one would also fall due at the sale, when the cash exists to pay it.

Where the cash problem actually sits

Move the figure’s sliders and a pattern appears. The capital gains tax is rarely the problem, because it is paid out of sale proceeds. The exercise tax is the problem, because it is paid out of savings, in the year of allotment, on a valuation the employee cannot realise. The higher the gap between strike and fair market value, the worse it gets, and a company that has raised a large round has made that gap larger for everyone.

Three company decisions change the employee’s position more than any tax planning they can do on their own. First, qualify for the deferral, if the company can, before the first exercise window. Second, let employees exercise when there is a buyer, by pairing exercise windows with secondary sales or a buyback, so that event one and event two fall in the same quarter. Third, give leavers a long post-termination exercise period, so that leaving the company does not force an exercise and a tax bill at the worst moment. Each of these is a board decision. None costs the company cash.

The capital gain is paid from the sale. The perquisite is paid from savings. Design the plan around the second.

Before every exercise window

Six weeks before an exercise window opens, confirm that a merchant banker’s valuation will be no more than 180 days old on the last day of the window, and commission one if not. Confirm whether the company holds an IMB certificate and is within its recognition limits, and write down whether the deferral applies. Send every eligible employee a one-page note with their own numbers: shares, exercise price, fair market value, perquisite, the tax and when it is due, and the holding-period date after which a sale becomes long-term. Tell payroll the month in which the perquisites will be booked. After the window, record each allotment date in the cap table, because it starts the holding clock. And at every exit interview, hand the leaver the date on which any deferred tax will fall due.

Nothing here is legal or tax advice; confirm the current rule with a chartered accountant or lawyer before acting.
