Introduction
You have worked hard at your job. You have earned stock options along the way What happens to stock options when you leave a company? Learn about vested vs. unvested options, exercise windows, tax rules, and steps to protect your equity.
But now you are thinking about leaving. What happens to stock options when you leave a company? This is a big question. And the answer can cost you thousands of dollars if you get it wrong.
The short answer is this: you get to keep your vested stock options, but you usually lose any unvested ones. However, you must act fast. Most companies give you only 90 days to exercise your vested options after you leave. If you miss that window, your options expire. And they are gone forever.
This guide will explain everything you need to know. We will cover the basics in simple terms. You will learn what to do before you give your notice. And you will understand how to protect the money you have earned.

What Are Stock Options?
Before we dive in, let us define stock options.
A stock option is not actual stock. It is a right to buy company stock at a set price in the future. This set price is called the strike price or exercise price.
Here is an example:
- Your company gives you options with a strike price of $10.
- In a few years, the company stock is worth $25.
- You can use your options to buy shares at $10, even though they are worth $25.
- You make a profit of $15 per share.
Stock options are a way for companies to reward employees. They give you a share in the company’s success. But they come with rules. And those rules change when you leave your job.
Vested vs. Unvested Options – What Is the Difference?
This is the most important thing to understand.
Vested options are options you have earned. You have met the company’s requirements, usually by working there for a certain amount of time. You own the right to exercise these options.
Unvested options are options you have not yet earned. They are still locked. You cannot exercise them.
Most companies use a vesting schedule. This is a timeline that shows when your options become yours. A common schedule is four years with a one-year cliff.
What does that mean?
- You must work for at least one year before any options vest.
- After that first year, 25% of your options vest all at once (the “cliff”).
- The remaining 75% vest gradually, usually monthly or quarterly, over the next three years.
What Happens to Vested Stock Options When You Leave?
Good news: you keep your vested options when you leave. But there is a catch. You must exercise them within a certain time frame. This is called the post-termination exercise period (PTEP).
If you do not exercise your vested options before the PTEP ends, you lose them. They expire. And any potential profit disappears.
Most companies give you 30 to 90 days to exercise your vested options. For Incentive Stock Options (ISOs), the IRS requires exercise within 90 days to keep their special tax status. We will explain ISOs and NSOs later.
Can You Extend the Exercise Window?
Sometimes, yes. Some companies offer longer exercise periods. This is more common at later-stage startups. You can also try to negotiate a longer window before you leave. But this is not always possible.
Key takeaway: Check your stock option agreement. Find out exactly how many days you have. Do not guess. The clock starts on your last day of work, not the day you give notice.
What Happens to Unvested Stock Options When You Leave?
This is the bad news. You almost always lose your unvested options when you leave.
If you have not worked long enough to earn those options, they disappear. You get nothing for them. This is why timing matters.
What Is Accelerated Vesting?
In some situations, your unvested options might vest faster. This is called accelerated vesting.
There are two types:
- Single-trigger:Â A single event, like a company acquisition, causes immediate vesting.
- Double-trigger:Â Two events must happen. For example, the company is acquired, and then you are laid off.
Accelerated vesting is not common for most employees. It is more often part of executive compensation packages. But it is worth checking your agreement.
The Post-Termination Exercise Period (PTEP)
The PTEP is the window of time you have to exercise your vested options after leaving. Think of it as a countdown clock.
Key facts about the PTEP:
- It usually starts on your last day of employment.
- It is typically 30 to 90 days.
- For ISOs, it cannot exceed 90 days under IRS rules.
- For NSOs, the company sets the period. It can be 30 days, 90 days, or even longer.
If you do not exercise your options within the PTEP, they expire. You lose the right to buy shares at your strike price. Any potential profit is gone.
Example: The 90-Day Clock
Imagine you leave your job on June 1. Your options have a 90-day PTEP. You have until August 30 to exercise them. If you do not exercise by August 30, your options expire.
ISO vs. NSO – Two Types of Stock Options
There are two main types of stock options. They have different rules and different tax treatments.
Incentive Stock Options (ISOs)
ISOs are special. They offer tax benefits if you follow the rules.
Key features:
- No ordinary income tax when you exercise.
- You may owe Alternative Minimum Tax (AMT).
- You must exercise within 90 days of leaving to keep ISO status.
- If you exercise after 90 days, they convert to NSOs.
Non-Qualified Stock Options (NSOs)
NSOs are more common. They are simpler but have less favorable tax treatment.
Key features:
- You owe ordinary income tax on the “spread” when you exercise.
- The spread is the difference between the strike price and the current stock price.
- The PTEP is set by the company. It is often 90 days but can vary.
Quick Comparison
| Feature | ISOs | NSOs |
|---|---|---|
| Tax at exercise | No ordinary income tax (but AMT may apply) | Ordinary income tax on the spread |
| Post-termination window | 90 days max | Set by company (often 90 days) |
| Who can get them | Employees only | Employees and non-employees |
Tax Implications When You Exercise Options
Taxes can be complicated. But here are the basics.
For NSOs
When you exercise NSOs, the “spread” is taxed as ordinary income.
Example:
- Strike price: $10
- Current stock price: $25
- Spread: $15 per share
- You exercise 1,000 shares
- Taxable income: $15,000
Your employer will usually report this on your W-2.
For ISOs
When you exercise ISOs, you do not pay ordinary income tax right away. But you may owe Alternative Minimum Tax (AMT).
If you hold the shares for at least:
- One year after exercise, and
- Two years after the grant date,
then any profit is taxed as long-term capital gains (lower rate).
If you sell too early, the profit is taxed as ordinary income.
Talk to a Tax Professional
Tax rules are complex. Always talk to a tax advisor before making big decisions about your stock options.
What If You Work for a Private Company?
If your company is private, exercising options is different.
Challenges:
- There is no public stock market to sell shares.
- You may not be able to sell your shares for years.
- You still have to pay the exercise cost and taxes.
Considerations:
- Check if the company allows secondary sales.
- Understand the company’s path to IPO or acquisition.
- Be prepared to hold the shares for a long time.
Many employees walk away from private company options because the cost to exercise is too high. The average cost to exercise and pay taxes in the U.S. is around $140,000.
5 Steps to Take Before Leaving Your Job
Do not wait until your last day. Take these steps before you give notice.
Step 1: Review Your Stock Option Agreement
Find your grant agreement. Read it carefully. Look for:
- Your vesting schedule
- Your exercise window (PTEP)
- The type of options (ISO or NSO)
- Any special clauses
Step 2: Check Your Vesting Status
Log into your equity portal (like Carta or Shareworks). See how many options are vested and unvested. If you are close to a vesting cliff, consider staying a little longer.
Step 3: Calculate the Cost to Exercise
Figure out how much it will cost to exercise your vested options. Include:
- The strike price × number of options
- Estimated taxes
Step 4: Understand Your Tax Situation
Talk to a tax professional. Understand the tax impact of exercising. This is especially important for ISOs and AMT.
Step 5: Make a Plan
Decide if you will exercise your options. If yes, gather the money you need. If no, understand that you will lose them.
Common Mistakes to Avoid
Mistake 1: Forgetting About Your Options
This happens more than you think. People leave jobs and forget about their stock options. Then the window closes. And the options expire.
Mistake 2: Missing the Deadline
Do not assume you have 90 days. Check your agreement. Some companies give only 30 days. Mark the deadline on your calendar.
Mistake 3: Not Understanding Taxes
Exercising options can create a big tax bill. Be prepared. Do not get surprised.
Mistake 4: Letting Fear Stop You
Exercising options can be expensive. But if your options are “in the money,” they have real value. Do not walk away from money you have earned without thinking it through.
Mistake 5: Quitting Right Before a Vesting Cliff
If you leave one day before your cliff vesting date, you lose everything. Plan your departure around your vesting schedule.
