vs slab rate if sold short-term
On an identical ₹2,80,000 perquisite and ₹5,00,000 capital gain from unlisted (startup) shares, selling at 30 months nets ₹6,59,000, capital gains taxed at a flat 12.5%. Sell the exact same shares at 12 months instead, and you net only ₹5,86,040, because short-term gains on unlisted shares are taxed at your income slab rate, not a flat rate. Waiting 18 more months to cross the 24-month long-term threshold is worth roughly ₹72,960 here.
ESOPs and RSUs in India trigger two entirely separate tax events, exercise and sale, and confusing the mechanics between them (or between listed and unlisted shares) is the single most common way people misjudge what an equity grant is actually worth after tax.

Open the India calculatorExercise and sale: two events, never double-taxed
At exercise, the perquisite, (FMV on the exercise date minus your exercise price) × shares, is added to salary income and taxed at your slab rate in that year, exactly like a bonus. Your employer deducts TDS on it. Because it's a slab-rate add-on stacked on top of your existing income, the exact same perquisite value generates different tax depending on what else you already earn that year, it's taxed at the marginal rate the addition itself pushes you into, not calculated from ₹0.
At sale, the cost basis for capital gains purposes is the FMV at exercise, the same figure already taxed as perquisite, not your original exercise price. That's deliberate: it's exactly why the two legs never double-tax the same rupee, the perquisite leg captures exercise-price-to-FMV appreciation, and the capital gains leg only captures further appreciation from FMV-at-exercise to your eventual sale price.

| Scenario | Perquisite tax | Capital gain | Gains tax | Net proceeds |
|---|---|---|---|---|
| Listed shares, LTCG (18mo hold) | ₹89,700 | ₹3,00,000 | ₹21,875 | ₹5,88,425 |
| Unlisted (startup), LTCG (30mo hold) | ₹58,500 | ₹5,00,000 | ₹62,500 | ₹6,59,000 |
| Unlisted (startup), STCG (12mo hold) | ₹58,500 | ₹5,00,000 | ₹1,35,460 | ₹5,86,040 |
Computed via PayMetric Labs' India ESOP/RSU calculator engine, FY 2026-27 rates. Listed row: 1,000 shares, ₹100 exercise price, ₹500 FMV at exercise, ₹800 sale price, 18-month hold. Unlisted rows: 2,000 shares, ₹10 exercise price, ₹150 FMV at exercise, ₹400 sale price.
The DPIIT startup deferral changes WHEN you pay, not HOW MUCH
Employees at a DPIIT-recognised startup with a Section 80-IAC exemption certificate can defer the perquisite TDS to the earliest of 48 months from the end of the assessment year of allotment, sale of the shares, or leaving the company (Section 392 from FY 2026-27, replacing the old Section 192(1C) reference). This is purely a cash-flow timing benefit, useful if you'd otherwise owe tax on paper gains for illiquid pre-IPO shares you can't easily sell, the perquisite value and slab-rate calculation itself doesn't change.
This calculator's other figures assume no deferral, since deferral only shifts timing, not the totals shown here.

Frequently asked questions
What are the two separate tax events an ESOP actually triggers?
Exercise and sale, taxed completely differently and at different times. At exercise, the 'perquisite' (fair market value at exercise minus your exercise price, times shares) is added to your salary income and taxed at your slab rate, this is Section 17(2)(vi), and your employer deducts TDS on it just like salary. Later, if and when you sell the shares, a separate capital gains tax event applies to the gain between the sale price and the FMV already taxed as perquisite, so the two legs never double-tax the same rupee.
Why did the same-size perquisite (₹2,80,000) generate different net proceeds depending on holding period in your unlisted-shares example?
Because the capital gains tax on the sale leg depends entirely on whether you cross the long-term threshold. For unlisted shares, that threshold is 24 months. Sell at 30 months (long-term) and the ₹5,00,000 gain is taxed at a flat 12.5% (₹62,500). Sell at exactly 12 months (short-term) and the same ₹5,00,000 gain is taxed at your income tax slab rate, stacked on top of salary plus the perquisite, which worked out to ₹1,35,460 in this example, more than double. Waiting those extra 18 months to cross the 24-month mark was worth roughly ₹72,960 in this scenario.
Why is the long-term threshold 24 months for unlisted shares but 12 months for listed ones?
It's a genuine structural difference in how Indian capital gains law treats listed versus unlisted equity, not an inconsistency. Listed shares (on a recognised exchange, STT paid) get the shorter 12-month long-term threshold and access to Section 112A's ₹1.25 lakh annual LTCG exemption. Unlisted shares, most pre-IPO startup ESOPs, need a full 24 months to qualify as long-term, and don't get any exemption threshold at all, that ₹1.25 lakh exemption is specific to Section 112A listed-equity gains.
What's the cost basis for the capital gains calculation, the exercise price or the FMV at exercise?
The FMV at exercise, not the exercise price you actually paid. This is exactly why the two tax events never overlap: the perquisite tax already captured the gain between exercise price and FMV at exercise, so the capital gains leg only taxes further appreciation from FMV-at-exercise to the eventual sale price. Confusing this (using exercise price as the capital gains cost basis) would double-tax part of the same gain.
What is the DPIIT-recognised startup deferral, and does it reduce the tax owed?
No, it defers WHEN the perquisite tax is due, not how much. Employees of a startup that's both DPIIT-recognised under Startup India and holds a Section 80-IAC exemption certificate can defer the perquisite TDS to the earliest of 48 months from the end of the assessment year of allotment, sale of the shares, or leaving the company. From tax year 2026-27, this runs under Section 392 (replacing the old Section 192(1C) reference), with the same 48-month/sale/exit triggers. The perquisite value and slab-rate calculation stay identical, this only changes the cash-flow timing of when TDS is actually collected.
Does the perquisite get taxed in isolation, or does it stack on top of my regular salary?
It stacks on top, and this matters a lot for how much tax it actually generates. A large perquisite added to an existing salary is taxed at the TOP of that combined income stack, at your marginal rate on the incremental amount, not calculated in isolation from ₹0. This is why the exact same perquisite value can generate very different tax bills for two people with different base salaries, the marginal rate that applies depends on where the perquisite lands on top of everything else you already earn that year.
Are there any costs this calculator doesn't model?
Yes, two specifically flagged as out of scope. Surcharge and cess on the capital gains leg itself aren't modelled (high earners crossing surcharge thresholds should add roughly 10-25% surcharge plus 4% cess on top of the LTCG/STCG figures shown), and this calculator handles a single exercise-and-sale event at one FMV/price point, real grants that vest and get exercised in tranches at different FMVs need each tranche calculated separately. Foreign-listed RSU grants (e.g. a US parent company's stock) and FEMA/foreign asset reporting are also out of scope.
