What are ESOPs?

Employee stock options give you the right to buy your employer’s shares at a fixed exercise price. You pay that price when you exercise, and the difference between the market value and the price is taxed as salary.

How to use this calculator

  2. Enter the number of shares and the fair market value per share on the exercise date, and the exercise price.

How ESOPs are taxed

At exercise: perquisite = (FMV on exercise date − exercise price) × shares → slab rate
On sale: gain = sale value − FMV on exercise date → capital gains

Worked example

Exercising 1,000 options at ₹100 when FMV is ₹500, with other taxable income of ₹25 lakh (new regime): perquisite ₹4,00,000, extra tax ₹1,24,800. For an eligible start-up and an exercise in tax year 2026-27, that tax is due by 2032-04-14 at the latest, or earlier if you sell or leave.

Frequently asked questions

When are ESOPs taxed?

Not when they are granted or vest, but when you exercise them: the fair market value on the exercise date minus the exercise price is taxed as salary. When you later sell, the rise above that FMV is taxed as capital gains.

How does the start-up tax deferral work?

If your employer is an eligible start-up, tax on the perquisite is payable within 14 days of the earliest of: 60 months after the end of the tax year of exercise, the date you sell the shares, or the date you leave the company (section 289(3)).

Which start-ups are eligible?

A company or LLP incorporated on or after 1 April 2016 and before 1 April 2030, with turnover up to ₹300 crore (raised from ₹100 crore by the Finance Act, 2026), holding a certificate of eligible business from the Inter-Ministerial Board (section 140(16)).

How is FMV decided for unlisted start-up shares?

A Category I merchant banker values the shares on the exercise date or a date up to 180 days before it (rule 15 of the Income-tax Rules, 2026).

Is the deferred tax calculated at future rates?

No. It is calculated at the rates in force for the tax year in which the shares were allotted (section 392(3)); only the payment is deferred.
