ESOPs: taxed at exercise, taxed again at sale, and deferred only for some

Short answer: an ESOP is taxed twice — as salary at exercise, and as capital gains at sale. The first is the painful one, because it falls due in cash on shares that may have no market. Employees of eligible start-ups can defer it; everyone else cannot.

Where the provisions sit under the 2025 Act

Worth citing from the new numbering for anything from tax year 2026-27 onwards — a reference to the old 192(1C) is to a provision that no longer exists in that form.

The two taxing points

Grant and vesting are not taxing events. Nothing happens for tax when options are granted or when they vest.

At exercise — salary

When you exercise, the difference between the fair market value on the exercise date and the exercise price you paid is a perquisite, taxed as part of your salary at your slab rate. Your employer deducts tax on it.

For unlisted shares the fair market value is determined on a prescribed basis — it is not simply the last funding round's headline number, though that often informs it.

At sale — capital gains

When you sell, the gain over the fair market value already taxed at exercise is a capital gain.

That step-up matters: your cost for capital gains is the FMV used for the perquisite, not what you actually paid. Without it the same gain would be taxed twice.

Why the exercise tax is the real problem

The tax at exercise is payable in cash, on a gain that is entirely on paper.

For an employee of an unlisted start-up:

• There is often no market to sell shares into.
• The tax is funded out of salary, for shares that cannot be disposed of.
• If the company later fails, tax has been paid on value that never materialised — and the resulting capital loss does not recover tax paid under the salary head, because capital losses cannot be set off against salary.

That asymmetry is the single most important thing an employee should understand before exercising. The decision to exercise is a decision to pay real tax on an unrealised, possibly illiquid, possibly worthless gain.

The start-up deferral

For employees of eligible start-ups — those holding the relevant certification under the start-up regime at s.140 of the Income-tax Act, 2025 (the old 80-IAC) — the tax at exercise can be deferred under s.392(3) / 289(3) (the old 192(1C)).

The deferral runs to the earliest of:

• a fixed period after the end of the relevant year;
• the date the shares are sold; or
• the date the employee ceases to be an employee.

Three things to be clear about:

• It is a deferral of payment, not an exemption. The perquisite is still taxed, and on the value at exercise.
• Leaving the company accelerates it. An employee who resigns triggers the liability, often at the worst moment — and with no sale proceeds to fund it.
• It depends on the employer's certification status, not on the company merely being young or private.

Holding period, and what it costs to sell early

The holding period for capital gains runs from the exercise date — not from grant, and not from vesting.

For unlisted shares, long-term treatment requires 24 months. Sell inside that and the gain is short-term, taxed at slab rates rather than the long-term rate. An employee who exercises and sells quickly in a secondary or buyback can find the whole gain taxed at slab, twice over in effect — once as perquisite, once as short-term gain.

Where the shares are eventually listed, the position and the holding period differ. See capital gains and portfolio taxation for how the sale side is computed.

If the shares are in a foreign parent

Common in Bengaluru: the employer is an Indian subsidiary, the options are over the overseas parent's stock.

The tax structure is the same two points. The reporting is where the risk concentrates:

• Foreign shares must be disclosed in Schedule FA, whether or not anything was sold, and whether or not any gain arose.
• That regime carries its own penalties, independent of the tax.

See Schedule FA from your broker statement and foreign income, RSUs and ESOPs. Where earlier years were never disclosed at all, the one-time window that settles them is FAST-DS 2026, open until 31 December.

Before you exercise

1. Calculate the tax falling due at exercise — not the paper gain, the cash payable.
2. Establish whether the deferral is available, which depends on the employer's certification.
3. Ask whether there is any route to liquidity — buyback, secondary — and on what timeline.
4. Note the 24-month clock from exercise if the shares are unlisted.
5. If the shares are foreign, plan the Schedule FA disclosure from the first year of holding.

This is a working reference, not the statute. For anything you are relying on, confirm the section text and the deferral period directly.
