Employee equity

ESOPs are taxed twice. Most people pay more than that.

Once when you exercise, as salary. Once when you sell, as capital gains. Between those two moments sits a number — the fair market value on the exercise date — that is taxed at the first and becomes your cost at the second. Miss the link and you pay tax on the same gain twice, and nothing in the process will stop you.

Two taxable events

Once at exercise, as salary. Once at sale, as capital gains. They are separate, and the second depends on the first.

The number that links them

The fair market value on the exercise date. It is taxed as perquisite, and it becomes your cost when you sell.

Where people overpay

Using the exercise price as cost at sale. That taxes the same gain twice, and nothing in the process stops you.

Your cost at sale is not what you paid at exercise.

It is the fair market value that was already taxed as a perquisite. Using the exercise price instead inflates the capital gain by exactly the amount you were taxed on as salary, so the same money is taxed twice. No form, no broker statement and no employer will flag this for you.

The lifecycle

Five moments, two of which cost you.

Knowing which stage triggers tax is most of the battle. The other stages only matter because they set up the two that do.

Grant

No tax

The company awards options or units. Nothing is yours yet and nothing is taxable. The grant letter fixes the exercise price and the vesting schedule, both of which matter later.

Keep the grant letter. It is the only record of the exercise price and the vesting dates, and you will need both years from now.

Vesting

Depends on the instrument

Your right becomes exercisable. For options, nothing is taxable yet — you still have to exercise. For restricted units, vesting and allotment usually happen together, so this is the taxable moment.

This is where ESOPs and RSUs diverge. An option vests into a right to buy. A unit vests into a share you already own.

Exercise or allotment

Taxed as salary

You pay the exercise price and receive shares. The difference between the fair market value on that date and what you paid is a perquisite, taxed at your slab rate as part of salary. The employer deducts tax at source on it.

The tax falls due whether or not you sell anything. Exercising without a plan for the cash is the most common way this becomes painful.

Holding

No tax

The shares are yours. The holding period for capital gains runs from the exercise or allotment date, not from grant and not from vesting.

Counting from the grant date is a frequent and expensive error on the sale calculation.

Sale

Capital gains

You sell. The gain is the sale price less the fair market value already taxed as perquisite. Rates depend on whether the shares are listed and how long you held them after exercise.

Your cost is the value already taxed, not the exercise price you paid. Getting this wrong taxes the same money twice.

A worked example

One grant, all the way through.

Illustrative figures at a 30% slab. Change any of them in the calculator.

Options granted 1,000 Exercise price fixed at grant
Exercise price ₹100 per share What you actually pay
Fair market value at exercise ₹400 per share Set on the exercise date
Perquisite ₹3,00,000 1,000 × (400 − 100), taxed as salary
Tax on perquisite at 30% plus cess ₹93,600 Deducted by the employer at source
Sale price after 18 months ₹700 per share Listed shares, long-term
Capital gain ₹3,00,000 1,000 × (700 − 400). Cost is the FMV, not ₹100
Tax on the gain ₹21,875 12.5% on the gain above the ₹1.25 lakh exemption
If you had used ₹100 as cost ₹75,000 Tax on a ₹6,00,000 gain — ₹53,125 more than owed

The vocabulary

Six words that decide the answer.

Exercise price

Also called the strike price. Fixed at grant and unchanged by anything that happens to the share price afterwards.

Fair market value

The value on the exercise date. For listed shares it follows the exchange price on that day; for unlisted shares it comes from a merchant banker's valuation.

Perquisite

A benefit received from employment. The exercise gain is treated as one, which is why it is taxed at slab rates as salary rather than as an investment gain.

Cost of acquisition

What your shares are treated as having cost you when you sell. For exercised options it is the fair market value already taxed, not the exercise price paid.

Cliff

A minimum period before any part of the grant vests. Leave before it and typically nothing vests at all.

Sell-to-cover

Selling part of the allotment immediately to fund the tax on the whole. Common with foreign parent companies and often the only practical way to exercise.

Where it goes wrong

The mistakes that cost real money.

Every one of these is avoidable, and every one of them is common.

Using the exercise price as your cost at sale

The single most expensive error. Your cost is the fair market value that was already taxed as perquisite. Using the exercise price taxes the same gain twice, and no system flags it.

Counting the holding period from grant

It runs from exercise or allotment. Options granted five years ago and exercised last month give you a share held for one month, whatever the grant letter says.

Assuming the employer's TDS settles it

TDS on the perquisite is deducted against a standard assumption, not against your full position. If you have other income, the shortfall is yours to pay through advance tax.

Exercising with no plan for the cash

The tax falls due at exercise even though you have sold nothing. People exercise on the last day of a post-resignation window and discover the bill afterwards.

Forgetting foreign shares in Schedule FA

Shares in a foreign parent are foreign assets and must be reported, on a calendar-year basis, once you are ordinarily resident. Non-disclosure falls under the Black Money Act.

Missing the Form 67 deadline

Foreign tax credit for tax withheld abroad has to be claimed on Form 67, filed before your return. Miss it and you can end up paying twice with no relief.
