ESOP vs RSU: Key Differences for Indian Employees
ESOPs and RSUs (Restricted Stock Units) are both equity compensation — but they work very differently. Indian employees of US tech companies often receive RSUs, while startup employees typically get ESOPs.
Core Difference
ESOP (Employee Stock Option): You get the option to buy shares at a fixed price (strike price). You only benefit if the current share value exceeds the strike price.
RSU (Restricted Stock Unit): You receive actual shares (or cash equivalent of shares) for free when they vest. No purchase required.
Side-by-Side Comparison
| Feature | ESOP | RSU |
|---|---|---|
| What you receive | Option to buy shares | Actual shares (or equivalent cash) |
| Payment at vesting | No (you pay strike price at exercise) | No cost — shares are delivered |
| Risk of value going to zero | Yes (if strike price > FMV) | No — RSUs always have some value |
| Tax at vesting | No tax at vesting; tax at exercise | Perquisite tax at vesting (FMV taxed as salary) |
| Tax at sale | Capital gains on (sale − exercise FMV) | Capital gains on (sale − vesting FMV) |
| Common at | Indian startups (unlisted companies) | US listed companies (Google, Amazon, etc.) |
| Expiry | Yes — options expire after 10 years or 90 days after leaving | No — shares are yours once vested |
RSU Example: Google Employee in India
Ravi works at Google India (Google LLC parent). He receives 100 RSUs vesting over 4 years (25/year):
- Year 1: 25 RSUs vest. Google share price = $150. Perquisite income = 25 × $150 × ₹84 = ₹3,15,000. Tax: ~₹94,500 at 30% bracket.
- Year 2: Ravi sells. Share now $180. Capital gain = 25 × ($180−$150) × ₹84 = ₹63,000. STCG at slab rate (held <24 months as unlisted, but Google is listed in India via ADR — complex rules apply).
ESOP "Underwater" Risk
ESOPs can become "underwater" — worthless — if the company's share price falls below the strike price. RSUs never go worthless (unless the company's value falls to zero).
Example: You have ESOPs at ₹200 strike. Company struggles, current FMV is ₹100. Your options are worthless — you'd be buying at ₹200 something worth ₹100. RSU holders in the same situation still have shares worth ₹100 each.
