ESOP Letters in India: Vesting, Cliff, Exercise Window and Tax

What is an ESOP, actually?

An employee stock option is a right to buy a specified number of shares at a specified price, the exercise price, after a specified period. It is not a shareholding. Until you exercise, you have no shares, no voting rights, no dividends and nothing to sell.

This distinction drives everything else. Because exercise requires you to pay the exercise price, an option only becomes valuable when the share is worth more than that price and you have both the money and the opportunity to exercise. Each of those three conditions is a place where an ESOP can quietly fail to deliver.

For an unlisted Indian company, ESOPs are issued under Section 62(1)(b) of the Companies Act, 2013, read with Rule 12 of the Companies (Share Capital and Debentures) Rules, 2014. The scheme needs approval of the shareholders by special resolution. Promoters, the promoter group and directors holding more than 10% of the equity, directly or indirectly, are generally not eligible, though recognised startups have relief from this restriction for a period after incorporation.

Vesting, cliff and the grant letter

Vesting is usually spread over three to four years with a one-year cliff, matching international practice. Rule 12 requires a minimum of one year between grant and vesting, so a one-year cliff is partly a legal requirement for companies under the Companies Act rather than only a commercial choice. After the cliff, vesting typically continues monthly or quarterly.

The grant letter is the operative document for you, and it is worth reading properly rather than filing. It should state the number of options, the exercise price, the vesting schedule, the exercise window during employment and after departure, what happens on a change of control, and whether the company has any right to buy back shares acquired on exercise. It will usually refer to the scheme for everything else, so ask for a copy of the scheme too. If neither document addresses the post-departure window clearly, that is the first question to ask.

Why is the exercise window the term that matters most?

Many Indian ESOP schemes give departing employees a short period, sometimes thirty or ninety days, to exercise vested options or lose them. That sounds administrative and is in fact decisive.

Consider what exercising requires in an unlisted company. You pay the exercise price in cash, you incur tax on exercise, and you receive shares you usually cannot sell because there is no market for them. An employee leaving a startup is being asked to spend real money and take on a real tax liability to acquire an illiquid asset within ninety days. A great many people simply cannot, and their vested options lapse back into the pool.

A growing number of Indian startups have extended post-exit windows to several years, or until a liquidity event, precisely because short windows undermine the point of the scheme. That is worth asking about before you join, because it is far harder to change once you are an employee about to leave.

Good leaver, bad leaver: what happens when you leave?

Most schemes distinguish between the circumstances of departure. The definitions vary a great deal, so read them rather than assuming. The table shows a common pattern, not a legal rule.

How are ESOPs taxed in India?

Indian ESOPs are generally taxed at two points. At exercise, the difference between the fair market value of the share on the exercise date and the exercise price is treated as a perquisite and taxed as salary income, with the employer ordinarily deducting tax at source. For unlisted shares, fair market value for this purpose is determined under the income-tax rules, typically on a valuation by a merchant banker.

At sale, the gain over the fair market value already taxed at exercise is taxed as capital gains. Whether it is short-term or long-term depends on how long you held the shares from the exercise date and whether they are listed. For unlisted shares, the holding period for long-term treatment has been twenty-four months. Rates and thresholds were changed in 2024 and the law has since been re-enacted, so confirm current figures with a tax advisor.

A deferral of the tax on exercise is available to employees of eligible startups, addressing the problem of paying tax on a share you cannot sell. Under the 1961 Act, the deferred tax became payable at the earliest of forty-eight months from the end of the relevant assessment year, the sale of the shares, or leaving the employer. Whether your employer qualifies and how the deferral reads under the 2025 Act are specific questions to check.

A worked example with numbers

Suppose you hold 2,000 vested options with an exercise price of ₹10 per share, and the merchant banker's valuation on the exercise date is ₹500 per share. To exercise, you pay ₹20,000 to the company. The perquisite is 2,000 × (₹500 minus ₹10) = ₹9,80,000, which is added to your salary income for that year. At a 30% slab rate, before surcharge and cess, that is about ₹2,94,000 of tax, which your employer will usually deduct from salary unless the startup deferral applies.

So exercising costs about ₹3.14 lakh in cash, for shares you probably cannot sell. If, three years later, the company is acquired at ₹1,200 per share, your capital gain is 2,000 × (₹1,200 minus ₹500) = ₹14,00,000, taxed under the capital gains rules. If the company fails, you have paid ₹3.14 lakh for nothing, and a capital loss is of limited use to most salaried people.

This is why the exercise window matters. With a ninety-day window you must make that ₹3.14 lakh decision almost immediately after leaving. With a ten-year window, you can wait until the outcome is clearer.

How do employees actually get cash from ESOPs?

In an unlisted company there are usually only three routes. The first is a company-run buy-back or a secondary sale arranged alongside a funding round, where an investor or the company buys a limited number of employee shares or options. The second is an acquisition, where the buyer pays cash for shares or replaces options with its own. The third is a listing, after which shares can be sold on the market subject to any lock-in that applies.

None of these is guaranteed, and the timing is not in your control. Some companies instead offer to cancel vested options in return for a cash payment, which avoids the need to exercise at all; check how such a payment is taxed before accepting. Ask how past liquidity events were handled, whether former employees were included, and what price was paid compared with the latest valuation.

A caution on section numbers

The Income-tax Act, 2025 came into force on 1 April 2026 and replaced the Income-tax Act, 1961, renumbering provisions throughout. Older articles, scheme documents and internal FAQs cite sections of the 1961 Act, and those references are now to a repealed statute even where the substance carries over.

For that reason this guide describes the shape of the tax treatment rather than quoting income-tax section numbers. If your ESOP documentation cites specific provisions, check them against the current Act with a tax advisor rather than assuming the renumbering was harmless.

Questions to ask before you accept

• What is the exercise window after I leave, and does it differ for good and bad leavers?
• What is the exercise price, and what was the most recent fair market valuation?
• What percentage of the fully diluted share capital does my grant represent, not just the number of options?
• What happens to vested and unvested options on a change of control: single trigger, double trigger or none?
• Does the company have a buy-back right over shares I acquire on exercise, and at what price?
• Has the company run a buy-back or liquidity programme for employees before?
• Is the company an eligible startup for the tax deferral, and does that apply to me?

What to negotiate

Most employees cannot change the scheme, but the grant letter and side terms are often negotiable, especially for senior hires. Reasonable asks include a longer post-exit window for good leavers, written in as 'Vested Options may be exercised at any time up to the earlier of ten years from the Grant Date and a Liquidity Event'; partial acceleration if you are terminated without cause within twelve months of a change of control; and a clear definition of cause limited to proven misconduct. If equity is replacing cash salary, ask for the trade-off to be explicit in rupees, so you can compare it with a cash offer.
