Employee Stock Option Plans (ESOPs) are increasingly common at Indian startups and tech companies — but they create a tax event at two separate points, often catching employees off guard with a tax bill before any cash has actually been realised from the shares.
Two Taxable Events in the Life of an ESOP
ESOP taxation in India happens in two stages:
- At the time of exercise — taxed as a perquisite (part of salary income)
- At the time of sale — taxed as capital gains
Stage 1: Taxation at Exercise — Perquisite
When an employee exercises their vested options (converting options into actual shares by paying the exercise price), the difference between the Fair Market Value (FMV) of the shares on the date of exercise and the exercise price paid by the employee is treated as a perquisite and added to the employee's salary income for that year — taxed at the employee's applicable slab rate.
Perquisite value = FMV on date of exercise − Exercise price paid
This amount is subject to TDS by the employer, just like regular salary. Critically, this tax liability arises even if the employee has not sold the shares and has received no cash — for unlisted company shares, this can create a significant cash-flow problem ("phantom tax").
How FMV Is Determined
- Listed company shares: FMV is the average of the opening and closing price on the stock exchange on the date of exercise (or the closest trading day).
- Unlisted company shares: FMV must be determined by a merchant banker's valuation report, typically obtained periodically (the valuation used should not be older than a prescribed period before the exercise date).
Stage 2: Taxation at Sale — Capital Gains
When the employee eventually sells the shares, capital gains tax applies on the difference between the sale price and the FMV on the date of exercise (which becomes the cost of acquisition for capital gains purposes — not the original exercise price paid).
Capital gain = Sale price − FMV on date of exercise
- The holding period is calculated from the date of exercise (not the date of grant or vesting) to the date of sale.
- For listed shares, holding beyond 12 months qualifies for long-term capital gains treatment; for unlisted shares, the long-term threshold is 24 months.
- LTCG and STCG rates and exemptions follow the same rules as for any other equity shares of that listing status.
The Deferred Tax Scheme for Eligible Startups
Recognising the cash-flow burden of perquisite tax on unlisted shares, the government introduced a relief for employees of eligible startups (registered with DPIIT under the relevant scheme): the TDS on the perquisite can be deferred to the earliest of:
- 5 years from the end of the relevant assessment year, or
- The date the employee sells the shares, or
- The date the employee leaves the company
This defers the cash outflow (TDS deduction) but does not change the fact that the perquisite value is still computed based on FMV at the date of exercise — it only delays when the tax must actually be paid.
⚠ "Phantom tax" risk for unlisted company ESOPs: If you exercise options in an unlisted company (not eligible for the deferral scheme) and the FMV has risen significantly since grant, you could owe substantial tax on paper gains with no liquidity to pay it — and if the company's value later falls before you can sell, you cannot recover the tax already paid on the higher exercise-date FMV.
Worked Example
An employee is granted options with an exercise price of ₹50/share. At exercise, the FMV (per valuation report) is ₹250/share, and they exercise 1,000 options.
- Perquisite value = (₹250 − ₹50) × 1,000 = ₹2,00,000, added to salary income and taxed at slab rate in the year of exercise.
- Cost of acquisition for capital gains = ₹250/share (the exercise-date FMV, not ₹50).
- If sold 3 years later (unlisted shares, so long-term) at ₹400/share: Capital gain = (₹400 − ₹250) × 1,000 = ₹1,50,000, taxed as long-term capital gains.
Frequently Asked Questions
Do I owe tax on ESOPs just by being granted options, before exercising them? ▼
No. Grant of options and vesting are not taxable events. The first taxable event occurs only when the employee exercises the vested options and actually receives shares — at which point the perquisite tax applies based on the difference between FMV and exercise price.
What happens to the deferred TDS if I leave the eligible startup before 5 years? ▼
The deferral period ends on the earliest of the three triggers — 5 years from the end of the relevant assessment year, sale of shares, or leaving the company (cessation of employment). If you leave the company, the deferred TDS becomes due at that point, even if you have not sold the shares.
Is the cost of acquisition for capital gains the exercise price or the FMV at exercise? ▼
It is the FMV on the date of exercise — this is because that FMV was already taxed as a perquisite (part of salary) at exercise. Using the exercise-date FMV as the cost basis for capital gains avoids double-taxing the same value as both perquisite and capital gain.
