Compute your perquisite tax at exercise and capital gains tax at sale. For Indian listed and unlisted company shares, with startup deferral notes.
This calculator estimates tax on ESOPs in two stages. At exercise: perquisite = (FMV on the exercise date minus exercise price) × shares, taxed as salary at your slab rate plus 4% cess. At sale: capital gain = (sale price minus that FMV) × shares, taxed at 20% or 12.5% for listed shares, or slab rate or 12.5% for unlisted shares, plus cess.
Sample values shown (1,000 listed shares, exercise price Rs 10, FMV Rs 450, sold at Rs 600 after 14 months, 30% slab). Change them to get your own number.
Enter your ESOP exercise details and click Calculate. Sale details are optional but needed for capital gains computation.
Two stages, two different tax treatments, explained clearly.
Your company grants you the right to buy shares at a fixed price (the exercise or strike price) in the future. There is no tax at the grant stage. The grant vesting schedule determines how many shares you unlock over time.
The grant price is usually the FMV at the date of grant, though for startups it can be a discounted price. The gap between the eventual FMV and this grant price is where your wealth (and tax) is created.
Vested shares are shares you have earned the right to exercise. Vesting creates no tax event by itself. The right to exercise a vested option continues until the option expiry date (typically 10 years from grant).
When you choose to exercise (buy the shares at the exercise price), you trigger the perquisite tax. The perquisite value is:
(FMV on exercise date minus Exercise price) multiplied by Shares exercised
This amount is added to your salary income for the year and taxed at your applicable slab rate. Your employer deducts TDS under Section 392 of the Income-tax Act, 2025 (earlier Section 192) and reports it in your TDS certificate, Form 130 from tax year 2026-27 (earlier Form 16). The FMV used is the average of open and close price on NSE/BSE for listed shares, or a merchant banker valuation for unlisted shares.
Exception: For employees of eligible startups (DPIIT-recognised and holding the Section 80-IAC certificate), TDS at exercise is deferred under Section 192(1C) to the earliest of 48 months from the end of the relevant assessment year, the date of sale, or the date you leave the company.
When you sell the shares, the gain from the FMV at exercise to the sale price is a capital gain. The rate depends on the share type and how long you held them after exercise:
Listed shares: STCG (sold within 12 months of exercise): 20% under Section 111A. LTCG (held 12 months or more): 12.5% under Section 112A, with a Rs 1.25 lakh annual exemption.
Unlisted shares: STCG (sold within 24 months of exercise): taxed at slab rates. LTCG (held 24 months or more): 12.5% without indexation.
A 4 percent health and education cess applies on all capital gains tax.
The capital gains rates set from 23 July 2024 apply for tax year 2026-27. Section numbers below (17(2)(vi), 111A, 112A, 192(1C)) are the 1961 Act numbering; the Income-tax Act, 2025 renumbers them.

You exercise 1,000 options in a listed company at an exercise price of Rs 10 when the FMV is Rs 450, you are in the 30% slab (new regime), and you sell 14 months later at Rs 600.
| Step | Working | Amount |
|---|---|---|
| Perquisite at exercise | (450 − 10) × 1,000 | Rs 4,40,000 |
| Tax on perquisite | 4,40,000 × 30% × 1.04 | Rs 1,37,280 |
| Capital gain at sale | (600 − 450) × 1,000, held over 12 months = LTCG | Rs 1,50,000 |
| Tax on LTCG | (1,50,000 − 1,25,000 exemption) × 12.5% × 1.04 | Rs 3,250 |
| Total tax | Rs 1,40,530 |
Most of the tax falls at exercise, before you have sold anything. That is why many employees sell part of the shares on the exercise date to cover the perquisite TDS. Surcharge is not included.
