ESOPs vs RSUs: How Each Is Actually Taxed
Stock-based compensation is increasingly common in Indian startups and MNCs, and ESOPs and RSUs get taxed in genuinely different ways — different trigger points, different amounts, and different risk if the company is unlisted. Here's the side-by-side.
| Feature | ESOP (Stock Options) | RSU (Restricted Stock Unit) |
|---|---|---|
| What you get | Right to buy shares at a fixed price (exercise price / strike price) | Free shares granted upon vesting — no purchase needed |
| Cost to you | You pay the exercise price when you exercise | Zero — shares are given free on vesting |
| Tax event 1 (Perquisite) | On exercise: (FMV on exercise date − Exercise price) × shares taxed as salary income | On vesting: FMV on vesting date × shares taxed as salary income (perquisite) |
| Tax event 2 (Capital Gains) | On sale: Gains above FMV on exercise date taxed as capital gains | On sale: Gains above FMV on vesting date taxed as capital gains |
| Capital Gains — Listed co. | STCG: 20% if held <12 months; LTCG: 12.5% if held >12 months (above ₹1.25L) | Same as ESOPs for listed companies |
| Capital Gains — Unlisted co. | STCG: Slab rate if held <24 months; LTCG: 12.5% if held >24 months | Same as ESOPs for unlisted companies |
| TDS by employer | Employer deducts TDS on perquisite value at exercise | Employer deducts TDS on perquisite value at vesting |
| Typical in | Indian startups, early-stage companies | MNCs, listed large-cap companies |
Why RSUs and ESOPs aren't interchangeable
The core difference is that an ESOP is a right to buy shares later at today's price, while an RSU is simply a promise of free shares on a future date. That's why ESOPs only create a tax event once you actively choose to exercise them, while RSUs tax you automatically the moment they vest — whether or not you wanted liquidity at that point.
Important: ESOP/RSU taxation is complex and highly situation-specific. The perquisite tax is deducted by your employer, reducing your in-hand salary in that period — a large vesting event can noticeably shrink one month's payslip even though no cash changed hands. Consult a qualified chartered accountant before exercising options or selling shares, especially for unlisted company ESOPs where valuation can be disputed by the tax authorities.
