Whether you're resigning for a new opportunity, being laid off, or negotiating an exit, the question of what happens to your unexercised stock options when you leave your job deserves attention well before your last day. The answer depends on your specific plan documents and how your employment ends — and the tax consequences look very different depending on what you decide to do.

This article walks through the general distinction between vested and unvested options, what typically happens on departure, and where the tax questions come in.

Vested vs. Unvested: The Key Distinction

Most option grants vest over time rather than all at once — you generally earn the right to exercise a portion of your options as you continue working, often on a schedule set out in your plan documents.

What Typically Happens When You Leave

  1. Your employment ends — by resignation, retirement, termination with cause, or termination without cause.
  2. Unvested options are generally forfeited, subject to your specific plan terms.
  3. Vested, in-the-money options usually remain exercisable for a limited window set by your plan — often a matter of weeks rather than months — after which they typically expire if not exercised.
  4. Vested options that are "underwater" (worth less than the exercise price) may simply lapse unexercised without any tax consequence, since exercising them wouldn't make economic sense.
  5. You (and your former employer) handle the tax consequences of any exercise that happens during or after this window, following the same general timing rules that applied while you were employed.

Because the exercise window is often short, this is not a decision to leave until the last minute — by the time you've thought it through, the window may have already closed.

Tax Consequences If You Exercise After Leaving

Exercising vested options after your employment ends generally follows the same rules as exercising while employed: you typically realize a taxable employment benefit based on the difference between the shares' value at exercise and what you pay, subject to whatever timing rules (immediate versus deferred, for CCPC shares) applied to your original grant. Leaving your job doesn't, on its own, change which set of timing rules applies — it mainly changes how much time you have to act.

When Termination Circumstances Complicate Things

If you're dismissed without cause, questions can arise about whether your entitlement to vesting, or to the exercise window itself, should be affected by the notice period you're owed under employment law — separate from the tax questions discussed here. Plan wording, the circumstances of the dismissal, and general employment law principles all factor in, and this is genuinely fact-specific territory rather than something with a single universal answer.

If you believe your options were cut off improperly, or that your entitlement during a notice period wasn't honoured correctly, that's a question worth raising with an employment or litigation lawyer, separately from — but often alongside — the tax analysis.

What to Do Before Your Last Day

Frequently asked questions

Do I lose all my stock options if I'm laid off?

Not necessarily. Vested options generally survive termination, at least for a limited exercise window set by your plan, while unvested options are typically forfeited. The exact outcome depends on your specific plan wording.

How long do I actually have to exercise after I leave?

This varies by plan and is often shorter than employees expect — sometimes just a matter of weeks. Confirm the specific window in your own plan documents rather than assuming a standard period applies.

If I resign voluntarily, does that change how my options are treated compared to being laid off?

It can. Some plans distinguish between resignation, retirement, termination with cause, and termination without cause, sometimes with different outcomes for each. Read your plan's specific termination provisions rather than assuming they're all treated the same.

What if my options are underwater when I leave?

If the exercise price is above the current share value, there's usually no economic reason to exercise, and the options can simply be allowed to lapse. Letting an underwater option expire unexercised generally doesn't, on its own, create a taxable event.
