Your ESOP grant letter is the single most important document you will sign at a startup. Most employees sign it without reading it properly. This guide tells you exactly what to look for and what the red flags are.
A grant letter is a legal contract between you and your employer. It specifies how many options you have been granted, what you pay to buy them, when you can buy them, and what happens to them if you leave. Getting these details wrong costs employees lakhs, sometimes crores in missed value or unexpected tax bills.

What Is an ESOP Grant Letter?
An ESOP grant letter is the document your employer issues when they grant you stock options. It is not the same as your employment contract. It is a separate legal document that governs your equity entirely.
The grant letter will typically cover: the number of options granted, the type of plan (ESOP, RSU, or SAR), your strike price, the vesting schedule, the and exercise window.
Every one of these sections matters. Here is how to read each one.
1. The Type of Plan
Your grant letter will specify which type of equity plan you are enrolled in. In Indian startups, the three most common are:
Employee Stock Option Plans (ESOPs): The most common in India. You are granted the right to buy company shares at a fixed price (your strike price) after a waiting period. You do not own shares until you exercise, and you cannot exercise until your options have vested.
Restricted Stock Units (RSUs): Less common in Indian startups, more common in MNCs with Indian subsidiaries. With RSUs, shares are given to you outright when they vest. You do not need to pay to exercise them. The tax treatment is different from ESOPs.
Stock Appreciation Rights (SARs): You benefit from the increase in share price without ever buying the shares. The company pays you the difference between the current price and the price at grant. Commonly used for consultants.
Why it matters: Each plan type has completely different tax treatment, exercise mechanics, and financial implications. Confirm which type you have before anything else.
2. Number of Options Granted
Your grant letter will state a specific number of options, for example, 5,000 options. This number matters, but it is not your wealth.
The common mistake: Employees multiply options by the current share price and assume that is what their ESOPs are worth. It is not.
Your real gain per option = Sale price − Strike price, after perquisite tax and tax on sale which either could be Short term capital gains or long term capital gain tax.
A large number of options at a high strike price can be worth less than a smaller number at a low strike price. Always calculate the gap between your strike price and the current share price but not just the absolute number of options.
3. Strike Price - The Most Important Number
The strike price (also called the exercise price) is the fixed price per share you pay when you exercise your options. This number is locked in on the day your options are granted.
What makes a strike price good: The lower your strike price relative to the current share price, the better. If your options were granted when the company was valued lower, your strike price will be low and every rupee the company grows above that price is potential gain for you.
Example:
- Strike price: ₹10
- Current share price: ₹200
- Your paper gain per option: ₹190
If you have 5,000 options, your unrealised gain is ₹9,50,000 – before tax and before exercise cost.
Red flag: If your grant letter says the strike price will be “fair market value at the time of exercise” rather than a fixed rupee amount today, then that is vague language that protects the company, not you. Your strike price should be a specific number stated clearly in the grant letter.
Another red flag: A strike price that is close to the current share price. This means the company needs to grow significantly before you see any real gain. It also means your exercise cost will be high relative to your potential upside.
4. Vesting Schedule
Vesting is the process by which you earn the right to exercise your options over time. Until an option vests, you cannot do anything with it.
The standard Indian startup vesting schedule: 1-year cliff, 4-year total vesting.
This means: nothing vests in the first year (the cliff). After 12 months, 25% of your options vest at once. After that, the remaining 75% vest in equal monthly or quarterly installments over the next 3 years.
Example: 5,000 options, standard 1-year cliff, 4-year vesting.
- After 12 months: 1,250 options vest (25%)
- After 24 months: 2,500 options vested in total
- After 36 months: 3,750 options vested in total
- After 48 months: 5,000 options fully vested
Performance-based vesting: Some plans link vesting to performance milestones like hitting revenue targets, completing a client engagement, or achieving specific goals. If your grant letter includes performance conditions, understand exactly what those conditions are and who decides whether they have been met.
What to check: Does your grant letter state the vesting schedule clearly? Is the cliff period defined? Is vesting time-based, performance-based, or both? Vague vesting conditions are a red flag.
5. Exercise Window - The Most Crucial Section
The exercise window is the period during which you can exercise your vested options. This is the section most employees do not read carefully enough and the one that causes the most financial damage.
Two exercise windows exist:
- During employment: Once your options vest, most plans give you the right to exercise them at any time while you are employed. Some plans restrict exercise to specific windows (quarterly, annually, or only at liquidity events).
- After you leave the company: This is the critical one. Most Indian startup ESOP plans give you 30 to 90 days to exercise your vested options after leaving the company for any reason, including voluntary resignation.
Why this is dangerous: Within that 30 to 90-day window, you must pay your exercise cost (strike price × number of options) plus the perquisite tax on the perquisite value – in cash – with no guarantee of ever being able to sell the shares. Most employees simply cannot afford to do this, and they walk away from their vested options entirely.
What good looks like: An exercise window of at least 1 year post-departure. Some progressive Indian startups now offer 5 to 10 years, following global best practices. This gives you time to assess the company’s trajectory and make an informed decision rather than a forced one.
What to check: How long is the post-departure exercise window? 30 days is a red flag. 90 days is standard but still tight. 1 year or more is genuinely employee-friendly.
6. Good Leaver and Bad Leaver Definitions
Almost every ESOP plan distinguishes between employees who leave under normal circumstances (good leavers) and those terminated for serious misconduct (bad leavers).
Bad leavers typically forfeit all unvested options which is reasonable. In some plans, bad leavers also forfeit vested options that have not yet been exercised.
Good leavers typically retain their vested options and have a defined exercise window to use them.
The red flag: Some plans define voluntary resignation as a bad leaver event. This means if you choose to leave the company – even after years of service you could be treated the same as someone fired for misconduct – you may lose the vested options as well.
What to check: Does your grant letter define good leaver and bad leaver clearly? Does voluntary resignation qualify as a good leaver event? What happens to vested options when you leave as a good leaver?
7. Liquidity Conditions
Some ESOP plans include a clause that says you can only exercise your options at a liquidity event meaning an IPO, acquisition, or company-initiated buyback. Until that event happens, you cannot do anything with your options, regardless of how many have vested.
Why this matters: If your company does not have a clear path to a liquidity event, your options may vest but remain locked indefinitely. You accumulate paper wealth with no way to access it.
What good looks like: A plan that allows you to exercise at any time after vesting not only at liquidity events. Even better: a company that has done ESOP buybacks in the past, showing they actively create liquidity for employees before an IPO.
8. Tax Implications - The Two Events
Your grant letter will not explain your taxes. But understanding them is essential before you decide to exercise.
When you exercise: The gain (current share price minus your strike price) is treated as employment income and taxed at your income slab rate, sometimes called as perquisite tax. If you are in the 30% bracket, you pay 30% of this gain in cash immediately, even though you have not sold any shares yet. Yes, it is a completely out of pocket expense if you don’t have any liquidity event in-sight.
When you sell: Any further gain from your exercise price to your sale price is taxed as capital gains. Hold for more than 24 months after exercising and you pay long-term capital gains tax at 12.5% above the ₹1.25 lakh threshold. Sell within 24 months and you pay short-term capital gains at your slab rate.
This is not double taxation. These are two different taxes on two different events and two different amounts.
The practical implication: Before you exercise, calculate your exact tax liability. Can you pay it in cash? If not, you need either a liquidity event or a secondary sale (selling to a fund like Hissa’s ESOP secondary fund) before exercising makes financial sense.
The 6-Point Grant Letter Checklist
Before signing your grant letter, confirm these six things:
1. Is my strike price a fixed rupee amount?
It should be a specific number, not a formula or reference to future fair market value. Make sure you can pay it in cash. If you cannot, understand what that means for your decision.
2. Is my strike price significantly below the current share price?
The wider the gap in your favour, the better your plan is.
3. What is my post-departure exercise window?
Anything less than 1 year deserves careful thought about whether you can afford to exercise if you leave early.
4. Am I defined as a good leaver if I resign voluntarily?
If voluntary resignation triggers bad leaver treatment, that is a serious red flag.
5. Can I exercise my options before a liquidity event?
Or are you locked in until an IPO or acquisition that may never happen?
6. What will my tax bill be if I exercise today?
Calculate it. Make sure you can pay it in cash. If you cannot, understand what that means for your decision.
What to Do If ESOP Grant Letter Looks Wrong
If your grant letter has terms that concern you like a short exercise window, vague strike price, bad leaver treatment on resignation, then raise it with HR before signing. Most Indian startups are open to discussion on exercise windows and leaver definitions, especially for senior hires.
If you are unsure how to interpret your grant letter, we have written a detailed blog on how to access if your ESOP plan is good, read through it or speak to someone who works with employee equity regularly.
