01What Are ESOPs?
An Employee Stock Option Plan (ESOP) is a benefit that allows an employee to purchase company stock at a pre-determined price, commonly called the strike price or exercise price. Indian startups frequently grant ESOPs to attract and retain key talent while conserving cash by rewarding employees for future growth instead of increasing present-day compensation.
The core promise of an ESOP is straightforward: if the company grows significantly, the gap between your fixed strike price and the higher Fair Market Value (FMV) represents real wealth. However, that wealth is not automatic. It requires deliberate action, correct timing, and an understanding of how the plan works when you are still at the company and, critically, when you decide to leave.
ESOPs exist in several forms: traditional stock options, RSUs (Restricted Stock Units), and ESPPs (Employee Share Purchase Plans). While this article focuses on stock options, the resignation rules and tax principles apply broadly to all equity-based compensation in India.
02What Happens to ESOPs When You Leave?
The moment you resign, a separate process begins for your ESOPs. Your salary stops automatically. Your options do not. But they move into a time-limited, action-required phase that most employees are unprepared for.
Here is the sequence of events that unfolds:
1The company calculates your vested and unvested count
Your last working day triggers an audit of your ESOP grant. The company’s HR or finance team will determine exactly how many options have vested (earned) and how many remain unvested (not yet earned) as of your exit date. This is the single most important calculation that determines your financial outcome.
2You receive a post-termination exercise notice
The company will notify you of your post-termination exercise period (PTEP). This is the window during which you are permitted to purchase your vested options. The length of this window varies by company, but most Indian startups set it at 30 to 90 days. Some larger or employee-friendly companies offer longer windows of six months or even three years.
3You decide whether to exercise
Within the exercise window, you must decide whether to exercise your vested options by paying the strike price per share. If you do, you become a shareholder. If you do not act before the window closes, your vested options typically expire permanently and return to the company’s ESOP pool. This is one of the most common and painful losses employees experience.
Each company has its own ESOP policy with different exercise timelines, paperwork requirements, and payment procedures. The general principles in this article apply broadly, but the specifics in your own grant agreement always take precedence. Read it before resigning.
03Vested vs. Unvested ESOPs: The Critical Distinction
| Aspect | Vested ESOPs | Unvested ESOPs |
|---|---|---|
| Ownership right | Yes, you have earned these | No, contingent on continued service |
| On resignation | Available to exercise within PTEP window | Forfeited on last working day |
| Action required | Yes, must actively exercise and pay strike price | None (they lapse automatically) |
| Exception | Expire if not exercised by PTEP deadline | Acceleration clause in acquisition events |
| Tax implication | Taxed as perquisite at exercise, capital gains at sale | No tax event (forfeited, no income received) |
1Vested ESOPs in detail
Vested ESOPs are the options you have earned by completing the required service period. If you hold 500 vested options at the time of resignation, you retain the right to purchase those 500 shares at your original strike price. However, they do not automatically become shares. You must actively exercise them, which means paying the strike price per share and completing the required paperwork. If you miss the post-termination deadline, those options expire and you receive nothing.
2Unvested ESOPs in detail
Unvested ESOPs are options you have not yet earned because you have not completed the required service period attached to them. These are forfeited when you resign. For example, if you were granted 2,000 options and only 800 have vested by your exit date, the remaining 1,200 unvested options are lost. The one exception is a plan-level acceleration clause, which is typically triggered only during a company acquisition or merger. Check your grant agreement for this specific provision.
04Understanding the ESOP Vesting Schedule
The vesting schedule is the timeline that determines when your options become yours. Understanding it precisely is critical before you resign, because leaving a few weeks too early can result in a material financial loss.
The most common structure in Indian startups is a 4-year vesting schedule with a 1-year cliff, which works as follows:
- For the first 12 months: no options vest, regardless of how well you perform.
- At the 12-month mark (the cliff): 25% of your total grant vests all at once.
- From month 13 through month 48: the remaining 75% vests gradually, typically on a monthly or quarterly basis.
- At the end of month 48: 100% of your grant has vested.
| Month of Resignation | Vesting Outcome (on 2,000 grant) | Impact |
|---|---|---|
| Month 11 | 0 options vested (cliff not met) | Full grant forfeited |
| Month 12 | 500 options vest (25% cliff) | 500 options exercisable |
| Month 18 | 500 + prorated portion of next 6 months | Approx. 750 options exercisable |
| Month 48 | 2,000 options fully vested | Full grant exercisable |
Resigning one or two weeks before a major vesting date (such as the 1-year cliff or an annual vesting anniversary) can result in a loss of hundreds of options. Before serving your notice, check your next vesting date and assess whether it is worth delaying your exit by a few weeks to capture that tranche.
05Can You Exercise ESOPs After Resignation?
Yes. For most companies, if an option has vested before your last working day, you are entitled to exercise those options after you leave. However, that right does not last indefinitely.
Most Indian startups, particularly early-stage ones, offer a 30 to 90-day post-employment exercise window. Some employee-friendly companies offer windows of six months to three years. Others, particularly those that haven’t updated their ESOP policies in years, may still have short 30-day windows written into older grant agreements.
Within this window, you must:
- Formally notify the company of your intent to exercise.
- Submit the required exercise form or documentation.
- Pay the strike price for each option you are exercising.
- Account for the perquisite tax liability that arises at the time of exercise (discussed in Section 8).
If you take no action within the exercise window, your vested options expire permanently. This is an extremely common loss. Employees get busy settling into a new role, assume they will decide later, and then find the window has closed.
If you hold 1,000 vested options with a strike price of Rs. 10 each and a 90-day window, failing to act costs you the right to purchase shares worth potentially far more than Rs. 10,000 at future FMV. Know your deadline before you serve notice, not after.
06Deciding Whether to Exercise Your ESOPs
Exercising stock options after leaving is a financial and strategic decision, not an automatic one. The fact that you can exercise does not mean you always should. Here is a structured framework to make this decision clearly.
1Assess the company’s future potential
Is the company growing? Are investors still actively backing it? Is the management team intact and capable? A startup with strong fundamentals and a realistic path to an IPO or acquisition gives your shares a meaningful chance of becoming liquid. A struggling company with no clear exit trajectory makes exercising a riskier bet.
2Understand the cost, including taxes
Exercising requires cash, not just for the strike price, but also for the perquisite tax that arises at the time of exercise. If the FMV at exercise is significantly higher than your strike price, the tax liability alone can be substantial. Never assume you can sell shares immediately to cover this cost. At a private startup, there is no immediate liquidity.
3Evaluate your risk tolerance
Exercising stock options in a private startup is an illiquid investment. The upside can be significant if the company succeeds. However, if the startup fails, the money spent exercising and paying taxes is completely lost. This is not a theoretical risk. Many Indian startups that raised large funding rounds have shut down before reaching a liquidity event.
Ask yourself three questions before deciding:
- Is the company likely to be worth significantly more in the future?
- Can I comfortably afford both the exercise cost and the associated tax liability right now?
- Am I prepared to hold these shares for several years before they become liquid?
If you answer yes to all three, exercising likely makes sense. If any answer raises concern, proceed carefully and consult a financial adviser before acting.
“Employees who benefit most from ESOPs are almost never those with the biggest initial grant. They are the ones who understood the rules, did the math, and acted rationally before ending employment.”
Ankit Sarawagi, CFOmatrix07Common ESOP Mistakes Employees Make Before Leaving
After working with dozens of founders and finance leaders across Indian startups, these are the patterns I see most often when employees lose ESOP value at exit:
1Resigning just before a vesting event
Leaving one or two weeks before a cliff date or annual vesting anniversary forfeits that entire tranche. A 25% cliff on a 2,000-option grant represents 500 options. Always know your next vesting date before you hand in your notice.
2Letting the exercise window expire
This is the single most common ESOP loss event. Employees intend to decide later, start a new job, get busy, and the 90-day window closes. The options are gone permanently. Set a calendar reminder for 15 days before the exercise deadline and treat it as a hard financial deadline.
3Never reading the ESOP grant agreement
Many employees have never read their grant agreement in full. This document contains your vesting schedule, exercise window, strike price, transfer restrictions, and rights in a liquidity event. Not reading it means you are making financial decisions in the dark.
4Assuming vested options automatically become shares
This is a widespread misconception. Vested options give you a right to purchase shares. They do not automatically convert. You must take active steps and pay the strike price to own the actual shares.
5Being blindsided by the tax bill at exercise
Many employees exercise their options without understanding that a perquisite tax liability arises immediately at the time of exercise. If you exercise 500 options where FMV is Rs. 100 and your strike price is Rs. 10, you owe income tax on Rs. 90 per share, totalling Rs. 45,000 in taxable income on that transaction alone. This cash must come from your own pocket since the shares in a private company cannot be immediately sold.
6Confusing paper valuation with personal wealth
A startup valued at Rs. 500 crore in its last funding round does not mean every ESOP holder is wealthy. Until there is an actual liquidity event (acquisition, IPO, secondary sale), ESOP value is entirely on paper. Many employees have exercised options at high valuations and held illiquid shares through a company’s decline to zero.
08ESOP Taxation in India: Two Stages You Must Understand
Before exercising any options, you need a clear understanding of how ESOPs are taxed in India. There are two distinct tax events, and both can be significant.
1Tax at exercise: Perquisite income
When you exercise your options, the difference between the Fair Market Value (FMV) on the date of exercise and your exercise price (strike price) is treated as a perquisite under Section 17(2) of the Income Tax Act. This amount is added to your salary income for that year and taxed at your applicable income tax slab rate.
Example: If your strike price is Rs. 10 per share and the FMV at exercise is Rs. 50 per share, you are taxed on Rs. 40 per share. For 500 shares, that is Rs. 20,000 of taxable perquisite income added to your salary for the year, regardless of whether you sell the shares or not.
Many employees find this counterintuitive because no cash has been received. You exercise, you pay for shares, and yet you owe tax immediately. In a private startup, this tax must be paid from your own savings. There is no sell-to-cover option as there would be with listed shares. Plan for this cash requirement before you exercise.
2Tax at sale: Capital gains
When you eventually sell the shares, a second tax event occurs. The gain between your FMV at exercise (which becomes your cost of acquisition for tax purposes) and the actual selling price is subject to capital gains tax.
| Share Type | Holding Period for LTCG | LTCG Rate | STCG Rate |
|---|---|---|---|
| Unlisted shares (private startup) | 24 months | 20% with indexation | As per slab rate |
| Listed shares (post-IPO) | 12 months | 10% (above Rs. 1 lakh gain) | 15% |
ESOP taxation in India involves multiple provisions of the Income Tax Act and can be complex depending on your specific situation, the type of company, and changes in tax law. This article is purely for informational purposes and should not be considered tax advice. Always consult a qualified tax professional before exercising substantial ESOP holdings.
09Liquidity and Exit Scenarios: What Happens Next?
Even if you exercise your ESOPs after resigning and become a shareholder, the real financial outcome depends on what happens to the startup. Here are the four primary scenarios every ESOP holder needs to understand.
1The startup is acquired
If the startup is acquired, your shares may be bought out as part of the transaction or exchanged for shares in the acquiring company. The outcome for vested versus unvested ESOP holders depends heavily on the acquisition agreement and the specific terms of your ESOP plan. In a strong acquisition, former employees with exercised shares can receive significant payouts. In a distressed acquisition, the consideration per share may be very low or nil.
2The startup goes public (IPO)
An IPO creates automatic liquidity. Once the company lists on a stock exchange, your shares become tradeable, subject to any lock-up period that applies to employees and early shareholders. This is typically the most financially rewarding outcome for ESOP holders who exercised and held shares through the company’s growth. Check your shareholder agreement for lock-up terms before assuming you can sell immediately after listing.
3The startup raises additional funding
Additional funding rounds may increase the paper valuation of the company and therefore your shares on paper. However, they do not create liquidity. You cannot sell private shares on a public exchange. You may find opportunities in secondary markets or through specific buyback programs that some larger startups run, but these are exceptions rather than the rule. Paper wealth is not real wealth until a liquidity event occurs.
4The startup shuts down
This is the downside scenario that every ESOP holder must factor in. If the company goes into liquidation or shuts operations, shares in the company may be worth nothing. All money spent exercising options and paying perquisite tax at the time of exercise is lost. ESOP decisions must always consider this scenario. Investing in a private company carries real risk, and ESOP exercise is effectively an investment decision.
10Questions to Ask HR Before You Resign
A few hours of preparation before you hand in your notice can protect years of equity earned. Here are the exact questions every ESOP-holding employee should ask before resigning:
- What proportion of my ESOPs is currently vested versus unvested? Get the exact number as of your proposed last working day.
- What is the post-termination exercise period under my specific grant agreement? Do not assume it is 90 days. Verify the exact duration.
- What is the current exercise price (strike price) for my options?
- What is the current Fair Market Value of the shares? This determines your potential gain and the perquisite tax liability you will face at exercise.
- What is the exact exercise procedure after I leave? What forms need to be submitted? To whom? Via what channel?
- Are there any upcoming liquidity events, fundraises, or secondary buyback programs planned?
- Are there any transfer restrictions on shares I purchase after exercising?
- Are there any specific terms in my grant that affect what happens on resignation? Acceleration clauses, clawback provisions, and so on.
Asking these questions is not confrontational. It is financially prudent. A well-run startup’s HR team or finance function should be able to answer all of them clearly. If they cannot, that itself is useful information about how the company manages its ESOP program.

11Frequently Asked Questions
What happens to an ESOP when I resign?
Generally, your vested ESOPs remain available for you to exercise for a defined period after you leave, typically 30 to 90 days. This is called the post-termination exercise period. Your unvested ESOPs are normally forfeited on your last working day. Vested options do not automatically convert to shares. You must actively exercise them by paying the strike price before the deadline.
Can I exercise ESOPs after resignation?
Yes. Most companies permit employees to exercise vested options after resignation, but only within the post-termination exercise window specified in your grant agreement. This window is typically 30 to 90 days at Indian startups, though some companies offer longer periods. After the window closes, your options expire permanently with no recourse.
What happens to unvested ESOP options when I quit?
Unvested options lapse automatically on your last working day because vesting is contingent on continued employment. The only exception is an acceleration clause in your grant agreement, which is typically triggered only in a company acquisition. If your agreement contains no such clause, unvested options are forfeited without any compensation.
What is the typical ESOP vesting period in Indian startups?
The most common structure is four years with a one-year cliff. No options vest during the first year. At the one-year mark, 25% of your total grant vests at once. The remaining 75% then vests monthly or quarterly over the next three years. Leaving just before the cliff or an annual vesting date results in losing that tranche entirely.
How are ESOPs taxed in India when I resign and exercise?
ESOP taxation in India happens at two stages. At exercise, the difference between FMV and the strike price is treated as a perquisite and taxed as salary income at your slab rate. This tax applies even though you have not sold the shares and received no cash. At sale, the gain over FMV is taxed as capital gains, either short-term or long-term depending on how long you held the shares. Always consult a tax professional before exercising substantial holdings.
Is it advisable to exercise ESOPs upon resignation?
It depends entirely on your situation. Consider three questions: Is the company likely to be worth significantly more in the future? Can you comfortably afford both the exercise cost and the resulting tax liability? Are you prepared to hold illiquid private shares for several years? If you answer yes to all three, exercising may make sense. If any answer raises concern, tread carefully. Consult a financial adviser familiar with startup equity before deciding.
What questions should I ask before resigning if I hold ESOPs?
Key questions to ask HR or the company’s finance team: How many of my ESOPs are vested and how many are unvested as of my last working day? What is the exact post-termination exercise window in my grant agreement? What is the current Fair Market Value? What is the exact exercise procedure? Are there any upcoming liquidity events? Are there any transfer restrictions on shares I purchase?
Can vested ESOPs expire after resignation?
Yes. Vested ESOPs expire if you do not exercise them within the post-termination exercise window. This is one of the most common and preventable financial losses among startup employees. Once the window closes, the options lapse permanently and there is no legal recourse to recover them. Set a calendar reminder well before the deadline and treat it as a non-negotiable financial deadline.
