What happens to my stock options if I leave a startup?

Unvested options usually go away the day you leave. Vested options stay yours, but only for a short window, often 90 days, to exercise them by paying the strike price. Miss that window and they expire. Incentive stock options exercised more than three months after you leave are taxed as nonqualified options, so the spread at exercise counts as wages.

Options you have not vested usually disappear the day you leave.

A stock option grant vests over time, often four years with a one year cliff. When you leave, most plans cancel whatever has not vested yet. It goes back into the company pool, and nobody pays you for it.

There are exceptions, and they live in your grant paperwork. Some grants speed up vesting if the company is sold and you are let go, which is called acceleration. A few separation agreements add a little extra vesting. If you are not sure, read the grant agreement before your last day, not after.

Vested options come with a deadline, and it is usually short.

Vested options stay yours after you leave, but only for a while. The plan calls it the post termination exercise period. Ninety days is the most common length. Some companies give several years, and a handful give less. Once it passes, the options are gone for good, no matter how valuable the company becomes.

Incentive stock options, ISOs, carry their own tax deadline on top of that. To keep ISO treatment you generally have to exercise within three months of leaving. A longer company window does not change the three months. Exercise on day 100 and the options are taxed as nonqualified options, NSOs, which means the spread counts as wages.

Keeping your options costs real cash, often within weeks.

Exercising means paying the strike price for every share you buy. With NSOs, the spread between the strike and the current share value is taxed as wages in the year you exercise. With ISOs exercised in time, there is no regular tax at exercise, but the spread goes into the alternative minimum tax math and can create a bill the next April.

Illustrative arithmetic, not a tax estimate. You have 10,000 vested options with a 2 dollar strike, and the company's current 409A value is 8 dollars. Exercising costs 20,000 dollars. The spread is 60,000 dollars. As NSOs, that is 60,000 of wage income, and federal plus California tax on it can easily run close to 20,000 dollars. So keeping the options could take around 40,000 dollars in cash, for shares you probably cannot sell until the company goes public or gets bought.

This is where people get stuck: a new job, a 90 day clock, and a big check to write into a company they just left.

Moving out of California does not take the tax with you.

California generally taxes option income tied to the time you worked here, even after you move away. If you earned the options at a California startup and then moved to a state with no income tax, the part of the spread linked to your California work days can still land on a California return when you exercise.

The same goes for the sale later. Hang on to your grant agreement, your exercise confirmations, and your work location history. The person preparing your return will need all of it, and rebuilding it years later is painful.

Letting some options expire can be the right call.

You do not have to exercise everything. Plenty of people exercise a slice they could afford to lose completely and let the rest go. If the company fails, the shares you bought are worth nothing and the tax you paid does not come back.

There are other routes too. Before you resign, ask whether the company will extend the window, and know that an extension can change how ISOs are taxed. Some outside firms will advance the exercise cash in return for a share of any future payout. Read those terms closely, because the share they take can be large. And check whether the company can buy back exercised shares when you leave, and at what price.

What is a post termination exercise period?

It is the window your stock plan gives you after you leave to exercise vested options. Ninety days is common. When it ends, any options you have not exercised expire.

Do I lose my stock options if I get laid off?

Unvested options are usually cancelled whether you quit or are laid off. Vested options usually follow the same exercise window. A severance agreement or an acceleration clause can change that, so read both before you sign.

Can I extend the 90 day window after I leave?

Only if the company agrees, and it is far easier to ask before your last day than after. If your options are ISOs, exercising more than three months after you leave generally means they are taxed as NSOs instead.

What happens to my options if the startup is acquired after I leave?

Options that expired are gone. Shares you already exercised are usually bought out or converted into the buyer's stock on the deal's terms. Common shareholders get paid after preferred investors, so a sale does not always mean a payout.
