What Happens to My Stock Options If I Am Fired Before My Cliff?

Usually you lose them. Before the cliff, typically one year, nothing has vested, so a termination forfeits the whole grant unless your agreement provides acceleration. Options that have vested usually must be exercised within a short window, often 90 days.

Equity is often the part of an offer that makes a lower salary worthwhile, which makes it painful to learn how easily it disappears. Most startup grants vest over four years with a one-year cliff, and a termination before that first anniversary usually means walking away with nothing. Our guide to vesting cliffs and acceleration explains the mechanics; this one covers the situation of being let go, and what you can do about it before and after it happens. It also covers what happens to unvested stock options when you quit.

Key takeaways

  • Before a one-year cliff nothing has vested, so termination usually forfeits the whole grant.
  • Vested options usually must be exercised within a short window, often 90 days.
  • Incentive stock options generally keep favorable tax treatment only if exercised within three months of leaving.
  • Negotiate acceleration on termination without cause and a longer exercise window before joining.

Why does the vesting cliff matter so much?

A cliff is a period during which nothing vests. With a standard one-year cliff on a four-year schedule, 25% vests on your first anniversary and the rest vests monthly or quarterly after that. If you leave, or are let go, one day before the anniversary, you have vested nothing.

That is true whether you resign or are terminated, and whether the termination is for cause or not, unless your agreement says otherwise.

What acceleration can do

Acceleration clauses make some or all of your unvested equity vest early on a defined event.

  • Single-trigger acceleration vests equity on one event, usually a sale of the company.
  • Double-trigger acceleration requires two events, usually a sale followed by termination without cause within a set period.
  • Some agreements include partial acceleration on any termination without cause, even without a sale.

The exercise window for vested options

Vested options do not stay available forever after you leave. Most plans give you a post-termination exercise window, commonly 90 days, to buy the shares at your strike price. If you do not exercise in time, the options expire.

The 90-day figure is common partly for tax reasons: incentive stock options generally keep their favorable tax treatment only if exercised within three months of leaving employment. Some companies offer longer windows, sometimes years, but any option exercised after three months is typically treated as a non-qualified option for tax purposes.

How are RSUs different from stock options?

Restricted stock units work differently. They usually convert to shares automatically as they vest, so there is no exercise price and no window to worry about. Unvested RSUs, like unvested options, are normally forfeited on termination. At private companies, RSUs sometimes carry a second condition, such as a sale or IPO, before they settle.

A worked example

Elena joins a startup with 40,000 options vesting over four years, one-year cliff, and no acceleration. She is laid off after eleven months in a restructuring.

Nothing has vested, so all 40,000 options are forfeited. Had she been let go after thirteen months, 10,000 would have vested and she would have roughly 90 days to decide whether to spend her own money exercising them. Had her agreement included partial acceleration on termination without cause, she might have kept a portion even at eleven months.

What to negotiate before you join

  • Acceleration on termination without cause, even partial.
  • Double-trigger acceleration on a sale of the company.
  • A longer post-termination exercise window.
  • A shorter cliff, or monthly vesting from the start, in senior roles.
  • Early exercise rights, which let you buy unvested shares and start the capital gains clock.

If you are let go near the cliff

Ask. Companies sometimes agree to vest the first tranche, or to set the termination date after the cliff, as part of a severance package, particularly when you were close. It costs them little and helps a separation go smoothly. Raise it before you sign any release.

Sample wording you can send

Before joining: “Could the option agreement include vesting acceleration of the next twelve months if I am terminated without cause, and a post-termination exercise window of at least twelve months?”

When let go near the cliff: “As I am within a few weeks of my one-year cliff, I’d ask that the first vesting tranche be accelerated as part of the separation.”

Common mistakes

  • Counting unvested equity as part of your compensation before the cliff.
  • Missing the exercise window after leaving.
  • Not checking whether options are ISOs or non-qualified options before exercising.
  • Signing a severance release without first asking about the cliff.

Should you exercise vested options at all?

Exercising costs money: you pay the strike price for each share, and depending on the option type and the spread between strike price and current value, you may owe tax at exercise even though the shares cannot yet be sold. At a private company, those shares may be illiquid for years. Before exercising within a short window, weigh the cash required, the tax cost, and a realistic view of the company’s prospects, and consider speaking to a tax adviser.

What happens in an acquisition

If the company is acquired, your equity is governed by the plan and the deal terms. Unvested options may be assumed by the buyer, converted into the buyer’s equity, cashed out, or in some cases cancelled. Without acceleration, a sale can leave unvested equity subject to the buyer’s schedule or remove it entirely. Double-trigger acceleration exists precisely to protect employees who are let go after a sale.

What happens to options if you are fired for cause?

Plans often treat termination for cause more harshly, sometimes cancelling even vested options immediately. Check how your plan defines cause. A broad definition that includes vague performance concerns gives the company more room to use it than one limited to serious misconduct.

Incentive stock options and non-qualified options

Employee options usually come in two types. Incentive stock options can receive favorable tax treatment if holding-period rules are met, but exercising them can trigger alternative minimum tax, and they must generally be exercised within three months of leaving employment to keep their status. Non-qualified options are taxed as ordinary income on the spread between the strike price and the share value when you exercise. Your grant documents say which you have, and the difference can change the cost of exercising after you leave considerably.

Which tax rules decide what happens to your options after you leave?

The rules for incentive stock options are in Internal Revenue Code § 422. To keep ISO treatment, you must have been an employee from the grant date until no more than three months before you exercise (§ 422(a)(2)). If you leave because of a disability, that window is one year instead (§ 422(c)(6)). To get favorable long-term capital gains treatment when you later sell, you also must not sell the shares within two years of the grant date or within one year of exercising (§ 422(a)(1)).

There is also an annual cap. If the value of stock under ISOs that first become exercisable in any calendar year exceeds $100,000, measured at the grant date, the excess is treated as non-qualified options (§ 422(d)). Acceleration on a layoff or a sale can push more options into a single year and over that cap, which changes the tax cost of exercising. Options that lose ISO status are taxed as non-qualified options, with ordinary income on the spread when you exercise.

Early exercise, mentioned above, works through § 83(b) of the Internal Revenue Code: if you buy unvested shares, you can elect to be taxed on their value at purchase rather than as they vest, but the election must be filed within 30 days of the transfer and is generally irrevocable once made. If you then leave before those shares vest, the company typically has the right to buy them back under the grant terms. Because these rules interact with alternative minimum tax and state taxes, take tax advice before exercising during a post-termination window.

Private versus public companies

At a public company, vested options can usually be exercised and the shares sold at once, often in a single transaction, so the exercise window mainly determines timing. At a private company, you may have to pay cash to exercise and then hold shares you cannot sell until an acquisition or listing, which may never happen. That makes a short post-termination window far more consequential at a private company, and a longer window worth negotiating.

Quick checklist

  • Know your vesting schedule and cliff date.
  • Check for any acceleration on termination or on a sale.
  • Check the post-termination exercise window.
  • Know whether your options are ISOs or non-qualified options.
  • Check how the plan defines termination for cause.
  • Raise vesting before signing any severance release.
  • Take tax advice before exercising after you leave.

Key terms explained

These are the terms you are most likely to meet in the clause itself and in any correspondence about it, explained in plain English so you can read your own contract with confidence.

  • Vesting: earning the right to your equity over time.
  • Cliff: the initial period, often one year, before any equity vests.
  • Strike price: the price you pay per share to exercise an option.
  • Exercise window: the time after leaving during which you can exercise vested options.
  • Acceleration: early vesting on a defined event, such as a sale or termination without cause.
  • RSU: a restricted stock unit, which converts to shares on vesting without an exercise price.

Frequently asked questions

What happens to unvested options if I am fired?

They are usually forfeited, whether you are fired or laid off, unless your agreement includes acceleration.

How long do I have to exercise options after leaving?

Commonly 90 days, though some companies allow longer. Check your option agreement.

Can I negotiate to keep options if I am let go near my cliff?

Sometimes. Companies occasionally vest the first tranche or set the termination date after the cliff as part of a separation. Ask before signing a release.

Should I exercise my vested options after leaving?

It depends on the cost and the company's prospects. Exercising means paying the strike price and possibly tax at exercise, even if the shares cannot yet be sold, and shares in a private company may be illiquid for years. Weigh the cash required, the tax cost and a realistic view of the company before the window closes, and consider a tax adviser.

What happens to my unvested options if the company is acquired?

It depends on the plan and the deal terms. Unvested options may be assumed by the buyer, converted into the buyer's equity, cashed out or in some cases cancelled. Without acceleration, a sale can leave unvested equity on the buyer's schedule or remove it entirely. Double-trigger acceleration exists to protect employees who are let go after a sale.

Why do incentive stock options need to be exercised within three months?

Incentive stock options generally keep their favorable tax treatment only if exercised within three months of leaving employment, which is partly why 90-day exercise windows are common. Some companies offer longer windows, but an option exercised after three months is typically treated as a non-qualified option, taxed as ordinary income on the spread when you exercise.
