The perquisite tax on ESOPs in India applies at the moment you exercise your stock options: the fair market value of the shares on the exercise date, minus the exercise price you actually pay, is treated as salary income under Section 17(2)(vi) and taxed at your slab rates through TDS.1Income Tax Department. Employees – Benefits Allowable A second tax event follows when you sell the shares, with any further price movement above the exercise-date FMV taxed as a capital gain.
When You Actually Owe the Tax
An ESOP has three milestones: grant, vesting, and exercise. Only exercise triggers a tax bill. The grant date, when your employer offers you the options, creates a future opportunity and nothing more. The vesting period, during which you wait to earn the right to act, is equally tax-free. No income exists at either stage because you don’t yet own any shares.
The taxable moment arrives when you exercise and the company allots shares to you. You have converted a paper right into real ownership at a price below what the shares are worth on the open market, and the Income Tax Act treats that built-in discount as a perquisite for the year of allotment.1Income Tax Department.

One useful consequence: you can hold unexercised options for years without owing anything. The clock starts when you choose to act. Vesting schedules and company blackout periods limit your flexibility, but the timing is partly yours to control.
How the Perquisite Value Is Calculated
The formula is simple. Take the fair market value of the shares on the exercise date, subtract the exercise price you paid, and multiply by the number of shares allotted. Exercise 1,000 options at a strike price of ₹100 when the FMV is ₹500, and the taxable perquisite is ₹4,00,000.
The harder question is what counts as fair market value, and that depends on whether the company is listed.
Listed Company Shares
For shares listed on a recognised stock exchange, Rule 3(8) of the Income Tax Rules sets the FMV as the average of the opening price and closing price on the date you exercise.1Income Tax Department. Employees – Benefits Allowable It is mechanical and leaves little room for dispute.
Unlisted Company Shares
For an unlisted company, the valuation must come from a SEBI-registered Category I Merchant Banker, and the valuation date cannot be more than 180 days before the exercise date.1Income Tax Department. Employees – Benefits Allowable Without a transparent market price, self-certification by the employer would invite abuse, so the rule pushes the number to an independent professional.
How TDS Is Collected on the Perquisite
Your employer does not send you a separate bill. Under Section 192, the company deducts TDS on the perquisite value as part of your salary for the month the shares are allotted, using your average income tax rate for the financial year based on estimated total salary including the perquisite.
This creates a real cash-flow problem. The perquisite is a non-cash benefit, but TDS has to be paid in cash. Exercise options worth ₹13 lakhs on a monthly cash salary of ₹75,000 and one paycheck cannot possibly cover the withholding. Employers handle this in different ways: spreading the TDS across the remaining months of the year, asking the employee to deposit the tax amount directly, or requiring an immediate sale of a portion of the shares to fund the tax. Whichever route your employer takes, the obligation to deposit TDS with the government on time sits with the company.
Late deposits carry interest at 1.5% per month from the month of deduction through the month of actual payment. The employer must also report the perquisite value on Form 12BA, the detailed statement of non-cash benefits that accompanies Form 16 at year-end. If the employer misses this, you are still responsible for reporting the income correctly in your return.
Capital Gains When You Sell the Shares
Perquisite tax at exercise is only half the picture. When you eventually sell, any gain or loss between the sale price and the FMV on the exercise date is taxed separately as a capital gain. The exercise-date FMV becomes your cost of acquisition, which prevents the same discount from being taxed twice.2Income Tax Department. Sale of Shares – Taxation and Capital Gains
Say you exercised at ₹100 when the FMV was ₹500, and you have already paid perquisite tax on the ₹400 spread. If you later sell at ₹700, your capital gain is ₹200 per share, not ₹600. Sell at ₹450, and you have a capital loss of ₹50 per share to carry forward against future gains.
Holding Periods and Rates
The rate depends on how long you held the shares after exercise and whether the company is listed. For transfers on or after 23 July 2024:3Income Tax Department. Capital Gain
- Listed Indian shares held more than 12 months: long-term gains taxed at 12.5% on the portion exceeding ₹1,25,000 in the year, plus applicable surcharge and cess.
- Listed Indian shares held 12 months or less: short-term gains taxed at 20% where Securities Transaction Tax was paid on the sale.
- Unlisted shares held more than 24 months: long-term gains taxed at 12.5% without indexation.
- Unlisted shares held 24 months or less: short-term gains added to your total income and taxed at slab rates.
For shares in a foreign company, the long-term threshold is 24 months whether or not the shares trade on any foreign exchange. Long-term gains are taxed at 12.5% without indexation; short-term gains fall at your slab rate.2Income Tax Department. Sale of Shares – Taxation and Capital Gains
ESOPs From a Foreign Parent Company
Many Indian employees receive stock options from a foreign parent. The perquisite mechanics are the same: FMV minus exercise price at the exercise date, taxed as salary through Section 192 TDS by your Indian employer. Foreign ESOPs add compliance layers that domestic plans do not have.
Exercising foreign company options is a capital account transaction under FEMA. The amount remitted to buy the shares counts against the Liberalised Remittance Scheme’s annual ceiling of USD 250,000. If your exercise cost exceeds that limit in a financial year, the excess needs RBI approval. You must also file Form OPI with the RBI semi-annually within 60 days of the half-years ending 31 March and 30 September. Late filing attracts a penalty of ₹7,500.
Once you hold foreign shares, disclose them in Schedule FA of your income tax return, which captures foreign assets held as of 31 December of the relevant calendar year. The disclosure obligation begins the moment shares are allotted after exercise, not when you eventually sell. Failure to report can trigger penalties under the Black Money Act, and the department receives information under international exchange agreements, so unreported foreign assets draw disproportionate scrutiny.
Tax Deferral for Employees of Eligible Startups
Startup employees face a specific squeeze. A recent funding round can push the paper valuation high, generating a large perquisite, while the salary is modest and the shares cannot be sold on any exchange. The Finance Act, 2020 addressed this by deferring the TDS deposit. The perquisite is still recognised as income in the year of exercise, but the actual tax payment shifts to a later date.1Income Tax Department. Employees – Benefits Allowable
The employer must deposit the deferred tax within 14 days of whichever comes first among these three events:
- 48 months from the end of the assessment year in which the shares were allotted. For shares allotted on or after 1 April 2026, the Income-tax Act, 2025 extends this window to 60 months.
- The date you sell the shares. Once the equity has been converted to cash, the deferral rationale disappears.
- The date you cease to be an employee of the company.
The deferral does not reduce your tax. It is a timing benefit. And the tax is calculated at the rates in force for the financial year the shares were originally allotted, not the year the tax is finally paid.
Not every startup can offer this. The company must be recognised by the Department for Promotion of Industry and Internal Trade (DPIIT) as a startup and must hold a valid Inter-Ministerial Board certificate under Section 80-IAC of the Income Tax Act.4Startup India. DPIIT Startup Recognition and Tax Exemption Section 80-IAC eligibility requires the entity to be a private limited company or LLP, among other conditions. If your employer has not been through the recognition process, the deferral is not available and TDS follows the standard timeline.
Common Mistakes to Watch For
The most expensive error is treating the exercise date as the only tax event and being caught off guard by capital gains at sale. Plan for both stages. Exercise options worth ₹10 lakhs and hold for a year before selling at a further ₹3 lakh gain, and your total tax exposure spans two financial years and two different calculations.
Another common mistake is using the wrong cost of acquisition when computing capital gains. Your cost basis is the FMV on the exercise date, not the exercise price you paid. Using the exercise price effectively double-taxes the perquisite portion and overstates the gain.
Startup employees who rely on the deferral often forget the departure trigger. Changing jobs within the 48-month window (or 60 months for allotments from April 2026) means the full deferred tax becomes payable within 14 days. If you are sitting on a large deferred liability and thinking about a move, factor this into your timing and cash planning.
Employees with foreign company ESOPs routinely miss Schedule FA disclosures. Report them the year the shares are allotted, not the year you get around to it.
