The two taxable moments: exercise and sale
An Indian-company ESOP is taxed twice over its life, and keeping the two events apart is what makes the rest of it tractable.
The first moment is exercise — when you pay the exercise price and the shares come into your hands. The benefit you receive is the share's fair market value on that date minus what you paid for it, and India treats that gap as salary you've been paid in kind: a perquisite under Section 17(2). Because it is salary, your employer values it and deducts tax on it under Section 192, exactly as it would on a cash bonus. This is salary income, not capital gains.
The second moment is the sale. Whatever the shares are worth above the value already taxed at exercise is a capital gain when you sell them. The fair market value taxed at exercise becomes your cost base, so you are not taxed twice on the same slice — the gain is measured only on the further rise.
Which part of the exercise India actually gets to tax is a separate question from these two moments, and for someone who moved abroad it is the one that matters most.
Why your India workdays decide how much India taxes
An ESOP is a reward for service over the period between grant and vesting. So when that service was rendered partly in India and partly abroad, India's claim on the perquisite is limited to the part that relates to the work you did in India during that period — not the whole exercise just because the granting company is Indian.
The standard way to split it is by workdays: the India-workday days in the grant-to-vesting window over the total days in that window, applied to the perquisite. The treaty's employment-income article — the dependent personal services article (Article 15 in most of India's treaties, Article 16 in the India-US treaty) — is what supports taxing only the India-attributable slice and leaving the foreign-service slice to the other country.
| Where you worked between grant and vest | What India can tax at exercise |
|---|---|
| Entirely in India | The full perquisite |
| Partly in India, partly abroad | Only the India-workday proportion |
| Entirely abroad | Generally none of it |
The practical trap is that payroll rarely applies this split. An Indian employer's system usually withholds Section 192 TDS on the whole exercise, because it doesn't track your overseas workdays. The over-withheld amount is then recovered on your return, where the correct sourcing is established with your travel record — which is why the days you spent where, between grant and vesting, are worth documenting before you exercise.
The sale: listed versus unlisted shares
When you eventually sell, the head of income switches from salary to capital gains, and how that gain is taxed depends entirely on whether the shares are listed or unlisted — a distinction that matters a great deal for ESOPs, because many are in startups whose shares are not yet on an exchange.
For listed Indian shares, the gain over the exercise-date value follows the standard listed-equity rules: long-term (held more than 12 months) at 12.5% on the amount above the ₹1.25 lakh annual exemption under Section 112A, and short-term at 20% under Section 111A.
For unlisted shares — the common case for a startup ESOP before any IPO — the rules are different. The long-term holding period is longer (more than 24 months), the Section 112A/111A listed-equity rates don't apply, and where there is no quoted price the fair market value is established under the prescribed valuation rules rather than read off a screen. The cost base is still the value already taxed as the perquisite at exercise, so the gain is the rise above that.
If the company lists between your exercise and your sale, the parcel can move from the unlisted rules to the listed rules over its life — another reason the holding period and the listing status on the sale date both have to be pinned down before any rate is applied.
A worked example: Ananya exercises after moving to Dubai
Ananya was granted ESOPs by an Indian technology company while working in its Bengaluru office. The options vested over four years. Eighteen months in, she relocated to Dubai with the same group and kept working there; the options carried on vesting on the original schedule. She exercises a tranche after the move.
At exercise, the perquisite is the share's fair market value less her exercise price — say ₹20,00,000. Because part of the grant-to-vesting service was rendered in India and part in Dubai, India's claim is limited to the India-workday proportion of that ₹20,00,000. If roughly half the relevant workdays fell in India, around ₹10,00,000 is properly Indian-taxable as salary under Section 17(2); the dependent-personal-services article of the India-UAE treaty supports leaving the foreign-service half out of India's net. Her Indian employer's payroll, however, withheld Section 192 TDS on the full ₹20,00,000, so the over-withheld tax is reclaimed on her return once the workday split is established from her travel record.
Two years later she sells the shares. By then the company has listed, so the gain over the ₹20,00,000 exercise value is a listed-share capital gain — long-term at 12.5% over the ₹1.25 lakh exemption under Section 112A — with the exercise value as her cost base. The figures are illustrative; the structure — exercise sourced by India workdays, payroll over-withholding corrected on the return, sale as a capital gain over the exercise value — is the part that holds.
