ESOPs in India: tax at exercise and at sale, worked through

Two tax points, not one

An employee stock option is taxed when you exercise it and again when you sell the shares. The first is salary. The second is a capital gain. They happen in different years more often than not, at different rates, and the second one depends on whether the company is listed in India.

The principles are in our guide to ESOP, RSU and ESPP taxation. Here they are with numbers, under FY 2026-27 rates and the new tax regime, for one employee and one grant.

Tax point one: exercise

Say you earn a gross salary of ₹30 lakh, which is ₹29.25 lakh after the ₹75,000 standard deduction and already reaches the 30% slab. You hold 2,000 vested options with an exercise price of ₹150. You exercise when the fair market value is ₹650.

The tax on the perquisite is deducted by your employer like tax on a bonus, so it lands in the same month. That is the cash-flow problem with ESOPs: you need ₹6.12 lakh to end up with shares you may not be able to sell yet. Total income for the year is ₹39.25 lakh, under the ₹50 lakh surcharge line; above it, a 10% surcharge would apply too. The ESOP tax calculator runs this with your own numbers, and the income tax calculator shows the slab table.

What "fair market value" means depends on the company:

• Listed in India: the average of the opening and closing price on the exercise date.
• Unlisted: a valuation by a SEBI-registered Category-I merchant banker, dated no more than 180 days before exercise.

Tax point two: sale

Your cost for capital gains is the ₹650 fair market value, not the ₹150 you paid. The ₹500 difference was taxed as salary already. Using ₹150 would tax it twice, and it is the most common error in self-filed returns with ESOPs. The holding period starts on the date the shares are allotted after exercise, not the grant date and not the vesting date.

Say you sell all 2,000 shares at ₹900. The gain is ₹250 a share, or ₹5,00,000. In a later year with the same salary and no other long-term gains, here is the tax under each case:

"In hand" is the ₹18 lakh sale value less the ₹3 lakh exercise price, the ₹3.12 lakh exercise tax and the capital gains tax.

The spread between best and worst is ₹1,07,250 on the same ₹5 lakh gain. Two lines in that table explain most of it. Unlisted shares need more than 24 months before the gain becomes long-term, and they never get the ₹1.25 lakh exemption. And a short-term gain on unlisted shares is taxed at your slab, not at the 20% that applies to short-term gains on shares sold on an Indian exchange. The capital gains tax calculator lays out every asset class side by side, and our post on capital gains on stocks and property covers the general rules.

No TDS is deducted on the sale of shares by a resident, so a large sale usually means advance tax in that year. See advance tax on capital gains.

When the price falls after exercise

The exercise tax is computed on a price that can disappear. Suppose the shares fall to ₹400 by the time you sell:

You gained ₹5 lakh over what you paid, and ₹3.12 lakh of it went in tax. The ₹5 lakh capital loss does not reduce your salary. It can only be set against capital gains, this year or in the next eight, provided you file on time, which is what the tax-loss harvesting calculator helps you plan around.

This is not an edge case. Between 2 September 2025 and 2 September 2026, Swiggy closed down 37.2%, from ₹425.95 to ₹267.70, and Infosys 23.9%, from ₹1,498.70 to ₹1,140. An employee who exercised at the earlier price and held paid salary tax on value that later fell away.

The startup deferral

Employees of an eligible startup can defer the exercise tax. "Eligible" is narrow: the company must be recognised by DPIIT and hold the inter-ministerial board certificate for the startup tax holiday. Recognition alone is not enough, and the Startup India portal lists what the company needs. The tax then falls due within 14 days of the earliest of: 48 months from the end of the assessment year of allotment, the sale of the shares, or leaving the company. Only the timing moves. The tax is still worked out at the rates for the year of exercise.

If the company lists before you sell

Shares allotted while a company is unlisted can be sold after it lists. Then the listed-share rules generally apply at the sale: 12 months for long-term treatment and the ₹1.25 lakh exemption, with the condition that securities transaction tax is paid on the sale. Lock-in periods after an IPO can delay that sale. This is a point to confirm with a tax adviser before acting, because the dates decide the rate.

A short checklist

1. Cost basis is the fair market value on the exercise date, as shown in Form 16.
2. The clock starts at allotment.
3. Unlisted means 24 months and no exemption.
4. Budget the exercise tax in cash; a later fall does not refund it.
5. Concentration. Salary, bonus and a large share holding all depend on one employer. Selling some after exercise to spread the money across, say, a flexi-cap fund is a portfolio decision, not a tax one; investing a windfall covers how to stage it.

What these numbers do not tell you

The example assumes a 30% slab, a single sale and no surcharge, and it uses FY 2026-27 rates; a grant exercised in another year is taxed at that year's rates. Notified startups, buyback offers and shares held by a trust each have rules of their own. It is not tax advice, and nothing here suggests exercising, holding or selling any particular shares. For foreign-listed shares from a US parent, the rules differ again; the RSU and ESPP tax calculator covers those.
