What is an ESOP?
An Employee Stock Option Plan (ESOP) gives employees the right — but not the obligation — to buy a defined number of company shares at a fixed price (the "strike" or "exercise" price), usually after a vesting period. ESOPs are how startups, which can rarely match big-company salaries, give early employees a real stake in the upside they help create. A well-designed plan turns staff into owners; a sloppy one creates confused, frustrated employees holding pieces of paper they don't understand.
Vesting and cliffs explained
Vesting is the schedule on which an employee actually earns the right to their granted options. The market standard is four years with a one-year cliff. The cliff means that if the employee leaves before completing 12 months, they walk away with zero. On the cliff date, 25% of the grant vests in one shot, and the remaining 75% vests monthly (or quarterly) over the next 36 months. The cliff exists to protect the company from giving away equity to people who don't stay long enough to contribute meaningfully.
How to size the ESOP pool
Most Indian startups operate with an ESOP pool of 8–15% of fully diluted shares. The right number depends on how many key hires are still ahead of you and how generous you need to be to win them. A common pattern: top up the pool to 10–12% before each priced round, with the dilution coming from existing shareholders (i.e. founders) rather than the new investors. Founders often miss this fine print — read your term sheet carefully when it talks about an "option pool top-up."
Indian tax notes (Section 17(2))
In India, ESOPs are taxed at two points. First, when the employee exercises the options — the difference between the fair market value (FMV) on the exercise date and the strike price is treated as perquisite income under Section 17(2) and is taxed at the employee's slab rate. Second, when the employee sells the shares — any gain over the FMV at exercise is treated as capital gains. For DPIIT-recognised startups, Section 156 provides relief by allowing employees to defer the perquisite tax for up to 5 years (or until they sell or leave the company). Employees should always understand both events before exercising.
Common ESOP mistakes founders make
- Not communicating the value of grants in plain numbers — "5,000 options" means nothing without the share price and pool size.
- Setting strike prices too high, killing the upside for employees.
- Skipping the cliff and burning equity on people who leave in 6 months.
- Forgetting to renew the pool before a round, then watching investors negotiate it pre-money.
- No clear policy on what happens to vested options when an employee leaves — most plans only give 90 days to exercise.
- Granting in "shares" loosely without specifying common vs preferred and the latest 409A/FMV.
