Last reviewed: 25 September 2026. An ESOP is how cash-strapped startups compete for talent - by sharing equity upside instead of only salary. But a poorly designed plan creates tax surprises for employees and dilution headaches for founders. This guide covers sizing the pool, vesting and cliffs, valuation, the two points at which employees are taxed, and the documents that keep the plan and cap table clean.
At a glance
Sizing the pool
The ESOP pool - typically 8% to 15% of fully diluted equity - should be sized to your hiring plan and refreshed before funding rounds. Too small and you cannot hire; too large and founders dilute unnecessarily. Investors usually expect the pool to be created or topped up pre-money.
Vesting and cliff
A standard schedule is 4 years with a 1-year cliff: nothing vests for the first year, then options vest monthly or quarterly. This aligns employees with long-term value and protects the company if someone leaves early.
Companies Act rules that shape the plan
- Minimum vesting period: Rule 12 of the Companies (Share Capital and Debentures) Rules, 2014 requires at least one year between the grant of options and their vesting.
- Who can receive options: ESOPs cannot be granted to promoters, members of the promoter group, or directors who hold (directly or indirectly) more than 10% of the company's equity shares. A startup is exempt from this restriction for 10 years from its incorporation.
- Approval: the scheme needs a special resolution of shareholders, with the disclosures Rule 12 prescribes.
How employees are taxed
| Event | Tax |
|---|---|
| At exercise | Perquisite on (fair value minus exercise price), taxed as salary. For exercises from 1 April 2026: section 17(1)(d) of the Income-tax Act, 2025 (old 17(2)(vi)), with TDS by the employer under section 392 (old 192) |
| At sale of shares | Capital gains on (sale price minus fair value at exercise) |
Eligible startups can allow employees to defer the perquisite tax at exercise under specified conditions, easing the cash burden of paying tax on shares that are not yet liquid.
Deferral conditions
- The employer must be an eligible startup: DPIIT-recognised and holding the Inter-Ministerial Board certificate for the startup deduction under section 140 of the 2025 Act (old 80-IAC).
- Tax on the perquisite is deducted and paid within 14 days of the earliest of: expiry of 48 months from the end of the relevant year, the date the employee sells the shares, or the date the employee leaves the company.
- The deferral changes when the tax is paid, not how much. The perquisite value is fixed at exercise, even if the shares later fall in value.
Worked example
| Step | Figure |
|---|---|
| Options exercised | 5,000 |
| Exercise price | ₹40 per share |
| FMV on the exercise date (Category I Merchant Banker) | ₹175 per share |
| Perquisite taxed as salary | 5,000 x (₹175 - ₹40) = ₹6,75,000 |
| Later sale at ₹400 per share | Capital gain = 5,000 x (₹400 - ₹175) = ₹11,25,000 |
The cost for capital gains is the FMV already taxed as a perquisite (₹175), not the ₹40 actually paid, so the same ₹135 per share is not taxed twice. Whether the gain is long-term or short-term depends on how long the shares are held after allotment; unlisted shares held for more than 24 months are long-term. If the company is an eligible startup and the employee opts for deferral, the tax on the ₹6,75,000 perquisite is paid when the first of the deferral triggers occurs.
Valuation and documentation
For tax, the FMV on exercise of unlisted shares must be certified by a SEBI-registered Category I Merchant Banker (Rule 3(8)), on a date not more than 180 days before the exercise; a registered valuer may separately be needed for Companies Act purposes. Keep a board- and shareholder-approved scheme, grant letters with clear vesting terms, and a cap table that tracks every grant, vesting event and exercise.
RSUs and ESOPs from a foreign parent company
Employees of Indian subsidiaries often receive RSUs or options in the foreign holding company. The same two-stage tax applies: a perquisite when the shares are allotted or transferred, valued at their FMV on that date, with TDS by the Indian employer, and capital gains when the shares are sold. Three further points:
- Foreign asset reporting: a resident employee must report the foreign shares in Schedule FA of the income-tax return, even if nothing is taxable that year.
- FEMA: acquiring shares of a foreign company under an employee stock option or benefit scheme is permitted under the overseas investment rules, and any remittance to pay the exercise price goes through the bank under the applicable route. Keep the bank's documentation on file.
- Foreign tax credit: where the shares are sold abroad and tax is withheld there, relief depends on the applicable DTAA and the supporting forms, so plan the sale with both countries' rules in view.
Frequently asked questions
What is an ESOP and why do startups use it?
An Employee Stock Option Plan gives employees the right to buy company shares at a fixed price after a vesting period. Startups use ESOPs to attract and retain talent when cash salaries are limited, by sharing future equity upside.
How big should the ESOP pool be?
Most startups set aside roughly 8% to 15% of equity as an ESOP pool, sized to the hiring plan and typically topped up before each funding round. The right size balances talent needs against founder dilution.
What is vesting and a cliff?
Vesting is the schedule over which options are earned - commonly 4 years with a 1-year cliff, meaning nothing vests until 12 months, after which options vest monthly or quarterly. It ensures employees stay to earn their equity. Under the Companies Act rules, there must be at least one year between grant and vesting.
How are ESOPs taxed for employees?
There are two points of tax: a perquisite when the option is exercised (on the difference between fair value and exercise price), and capital gains when the shares are eventually sold. For exercises from 1 April 2026 the perquisite falls under section 17(1)(d) of the Income-tax Act, 2025 (old 17(2)(vi)) and the employer deducts TDS under section 392 (old 192). Eligible startups can defer the perquisite tax at exercise under specific conditions.
How is the exercise price set?
The exercise price is fixed in the plan, often at or near the fair market value at grant. For tax, the fair market value of unlisted shares on the date of exercise must be certified by a SEBI-registered Category I Merchant Banker, on a date not more than 180 days before the exercise; a registered valuer may separately be needed for Companies Act purposes.
Does an ESOP dilute founders?
Yes. Options that are exercised become shares and dilute all existing holders, which is why the pool is planned deliberately and refreshed at rounds rather than granted ad hoc.
Can only a company issue ESOPs?
Yes, in the share sense. ESOP pools, vesting and share issuance are company constructs - an LLP cannot replicate them, which is one reason equity-hungry startups incorporate as companies.
What documents govern an ESOP?
A board- and shareholder-approved ESOP scheme, grant letters with vesting terms, a Category I Merchant Banker's valuation for the perquisite (and a registered valuer's report where the Companies Act requires one), and cap-table records tracking grants, vesting and exercises.
