Canonical URL: https://www.aalekh.ai/calculators/esop [All calculators](/calculators) For individualsRates reviewed September 2026 # ESOP Tax Calculator: Perquisite on Exercise and Capital Gains ESOPs are taxed twice, at two different moments and under two different heads, and this calculator works out both. The first charge lands when you exercise the option and the shares are allotted: the difference between the fair market value on the exercise date and the price you actually paid is a perquisite under section 17(1)(d) of the Income-tax Act, 2025 (section 17(2)(vi) of the 1961 Act), taxed as salary at your slab rate with 4 percent cess on top. The second charge lands when you sell. The cost of acquisition is not the exercise price but the fair market value that was already taxed as a perquisite, under section 73(1) of the 2025 Act (section 49(2AA)), so no rupee is taxed twice. The holding period runs from the date of allotment, not from the grant and not from the exercise, which matters whenever allotment trails exercise by a few weeks. An employee of an eligible start-up under section 140 (section 80-IAC) gets breathing room on the first charge. Section 392(3) (section 192(1C)) lets the employer defer the deduction to the earliest of 60 months from the end of the tax year of allotment, the sale of the shares, or the day the employee leaves. That is the same deadline the 1961 Act expressed as 48 months from the end of the assessment year. Deferral moves the payment date; it does not reduce the tax. ## ESOP Tax Calculator Number of options exercised shares Exercise price per share The price actually paid by the employee on exercise. ₹ Fair market value per share on exercise Listed shares: the average of the opening and closing price on the exercise date.

Surcharge is not included above and is capped at 15% on the capital gains part. ## The formula Total tax = (FMV on exercise − exercise price) × shares × slab rate, plus (Sale price − FMV on exercise) × shares × capital gains rate Perquisite The value charged as salary on exercise: the fair market value on the exercise date less the amount actually paid by or recovered from the employee. Fair market value For a listed share, the average of the opening and closing price on the exercise date on the exchange with the highest volume. For an unlisted share, a merchant banker valuation. Cost of acquisition The fair market value already taxed as a perquisite, so the capital gain measures only the movement in price after exercise. Holding period Counted from the date of allotment to the date of transfer: more than 12 months for a listed share and more than 24 months for an unlisted one. Start-up deferral For an eligible start-up, the tax on the perquisite falls due within 14 days of the earliest of 60 months from the end of the tax year of allotment, the sale, or the employee leaving. Surcharge is not shown above. It follows the rest of your income and is capped at 15 percent on the capital gains part, while the perquisite is ordinary salary income and carries the full surcharge rates. ## How to calculate it 1. 1 ### Work out the perquisite on exercise Multiply the number of options exercised by the fair market value per share on the exercise date, less the exercise price per share. That figure is added to your salary for the tax year in which the shares are allotted and taxed at your slab rate, with health and education cess at 4 percent on top. 2. 2 ### Get the fair market value right For a share listed on one recognised stock exchange, the fair market value is the average of the opening and the closing price on the exercise date. Where it is listed on more than one, take the exchange that records the highest volume of trading that day. For an unlisted share, a merchant banker has to value it on the exercise date or on a date not more than 180 days earlier. 3. 3 ### Check whether the employer is an eligible start-up Only a company or LLP that holds a certificate of eligible business from the Inter-Ministerial Board, and so qualifies under section 140 (section 80-IAC), can defer the withholding. The employee still reports the perquisite in the return for the year of allotment, but pays the tax on the earliest of the three trigger events rather than straight away. 4. 4 ### Count the holding period from allotment The clock starts on the date the shares are allotted to you, not the date the option was granted and not the date you exercised. A listed share becomes long term after more than 12 months and an unlisted share after more than 24 months. Exactly 12 or 24 months is still short term, so a sale one day later can change the rate. 5. 5 ### Compute the capital gain on sale Deduct the fair market value that was taxed as a perquisite, plus any transfer expenses such as brokerage, from the sale consideration. Because the cost is the already-taxed value, the gain reflects only what the share did after exercise, and a fall in price produces a capital loss rather than a refund of the perquisite tax. 6. 6 ### Apply the rate and check advance tax A long-term gain is taxed at 12.5 percent, with the first ₹1,25,000 of listed equity gains exempt in a year. A short-term gain on a listed share with STT is 20 percent, and on an unlisted share it is added to total income at slab rates. A large sale late in the year still attracts advance tax from the instalment falling due after it. ## How an ESOP is taxed at each stage for FY 2026-27 (AY 2027-28) How an ESOP is taxed at each stage for FY 2026-27 (AY 2027-28) Stage What is taxed Rate Exercise and allotment FMV on the exercise date less the exercise price, as a salary perquisite Your slab rate plus 4% cess, withheld by the employer Sale of a listed share held more than 12 months Sale price less the FMV already taxed 12.5% on gains above ₹1,25,000 a year Sale of a listed share held 12 months or less Sale price less the FMV already taxed 20% Sale of an unlisted share held more than 24 months Sale price less the FMV already taxed 12.5% without indexation Sale of an unlisted share held 24 months or less Sale price less the FMV already taxed Your slab rate ## Worked example: 5,000 listed shares, sold 16 months after allotment Options exercised 5,000 Exercise price per share ₹10 FMV per share on the exercise date ₹250 Date of allotment 15 May 2026 Sale price per share ₹400 Date of sale 20 September 2027 Marginal slab rate 30% - Perquisite on exercise = (₹250 − ₹10) × 5,000 = ₹12,00,000 - Tax at 30% = ₹3,60,000, plus 4% cess of ₹14,400 = ₹3,74,400 - Cost of acquisition = ₹250 × 5,000 = ₹12,50,000, being the FMV already taxed - Sale consideration = ₹400 × 5,000 = ₹20,00,000, so the capital gain is ₹7,50,000 - Held 16 months from allotment, so the gain on a listed share is long term - Less the ₹1,25,000 exempt slice = ₹6,25,000 at 12.5% = ₹78,125, plus ₹3,125 cess = ₹81,250 Total tax across both stages = ₹4,55,650 ## Frequently asked questions How is an ESOP taxed when I exercise the option? The difference between the fair market value of the share on the date you exercise and the price you actually pay is treated as a perquisite and added to your salary for the tax year in which the shares are allotted. It is taxed at your slab rate with 4 percent health and education cess, and the employer withholds the tax under the salary withholding provisions. No cash has changed hands at that point, which is why the charge often comes as a surprise. What is the cost of acquisition when I sell ESOP shares? It is the fair market value that was taken into account when the perquisite was charged on exercise, not the exercise price you paid. Section 73(1) of the Income-tax Act, 2025, which carries forward section 49(2AA) of the 1961 Act, says so expressly. The effect is that the amount already taxed as salary is not taxed again as a capital gain, and the gain measures only the movement in price after exercise. When does the holding period for ESOP shares start? On the date the shares are allotted to you. It is not the date the option was granted, and it is not the date you exercised the option, although in many listed-company schemes those last two fall on the same day. Where allotment trails exercise by weeks, which is common in unlisted companies, the later date is what counts. A listed share becomes long term after more than 12 months and an unlisted share after more than 24 months. How is the fair market value of an ESOP share determined? For a share listed on a single recognised stock exchange, it is the average of the opening price and the closing price on the date the option is exercised. Where the share is listed on more than one exchange, you take the exchange that recorded the highest volume of trading in the share that day. For an unlisted share, a category I merchant banker has to value it, either on the date of exercise or on a date not more than 180 days earlier. Can an employee of a start-up defer the tax on ESOPs? Yes, if the employer is an eligible start-up holding a certificate of eligible business from the Inter-Ministerial Board. The tax on the perquisite is then payable within 14 days of the earliest of three events: 60 months from the end of the tax year in which the shares were allotted, the date the shares are sold, or the date the employee ceases to be an employee. The 1961 Act expressed the same deadline as 48 months from the end of the assessment year. What happens if I sell the shares for less than the FMV taxed on exercise? You still owe the tax on the perquisite. The perquisite was fixed at exercise and does not reverse, so a later fall in price gives you a capital loss on the sale rather than a refund of the salary tax. That loss can be set off against other capital gains in the year and carried forward for eight years, but it cannot be set against salary. This mismatch is the single biggest risk in holding on to ESOP shares after exercise. What are the capital gains rates on ESOP shares for FY 2026-27? For a listed share sold with STT, a long-term gain after more than 12 months is taxed at 12.5 percent, with the first ₹1,25,000 of long-term listed equity gains exempt in a year, and a short-term gain is taxed at 20 percent. For an unlisted share, a long-term gain after more than 24 months is taxed at 12.5 percent without indexation, and a short-term gain is added to total income and taxed at your slab rate. Cess at 4 percent applies on top in every case. ## Sources Rates and rules on this page come from the following.
