Stock Options vs RSUs at Layoff — Decision Framework
By Severance Calculator Editorial · Updated
Who this applies to
The single most important question to answer at layoff if you hold equity is: what instrument do I have? Incentive stock options (ISOs), nonqualified stock options (NSOs), restricted stock units (RSUs), and performance-vested or double-trigger RSUs each have entirely different forfeiture rules, post-termination windows, tax treatment, and cash requirements. Applying the wrong framework to the wrong instrument is one of the most common and costly mistakes in layoff negotiation. Most employees at technology companies hold a mix of instruments — ISOs from early in their tenure when the company was private, NSOs for grants above the ISO limits, and RSUs that replaced or supplemented options once the company went public. Understanding each bucket separately is essential. The same separation date, the same stock price, and the same number of shares can produce radically different tax outcomes and required actions depending solely on the instrument type. This page is the decision framework. For deep dives on AMT mechanics (ISO holders), purchase-period unwind (ESPP holders), or RSU clawback/acceleration specifics, see the linked related pages.
What changes for you
For ISO holders, the core rule is 26 U.S.C. § 422(a)(2): an option is an incentive stock option only if it is exercised while the holder is employed or within three months of ceasing employment. The three-month clock is statutory and cannot be extended without converting the option to an NSO. The tax consequence of missing the window is real: at exercise the spread becomes ordinary income (not just AMT-preference income), and the option loses the potential for long-term capital gain treatment on the full spread. A laid-off ISO holder must (a) calculate the spread and potential AMT, (b) decide within 90 days whether to exercise, and (c) coordinate the cash required to pay both the strike price and any resulting AMT liability. See /scenarios/iso-amt-trap-90-day-window for the full AMT analysis. For NSO holders, there is no ISO benefit to lose — NSOs have always been subject to ordinary income recognition at exercise under 26 CFR § 1.83-7. The spread at exercise (the difference between fair market value on the exercise date and the strike price) is immediately ordinary income, subject to supplemental wage withholding and FICA. The post-termination exercise window for NSOs is not set by statute; it is set by the grant agreement — commonly 30, 60, or 90 days, but some employer plans allow 1–5 years. Read the grant agreement. The strategic question for NSO holders is whether to exercise immediately (triggering income in the layoff year when income may otherwise be low) or wait to see whether the stock price changes, subject to the grant-agreement deadline. For single-trigger RSU holders, the primary rule is that unvested RSUs are forfeited at termination unless the separation agreement provides for acceleration. Under 26 U.S.C. § 83(a), RSU income is recognized when the substantial risk of forfeiture lapses — which for unvested RSUs at termination never occurs, so no income and no tax on the forfeited shares. The action at layoff is negotiation: request acceleration of the next tranche, request that the separation date be set after the next vest, or request a cash payment equal to the forfeited value. Vested but unsettled RSUs should already be settled or settling on the normal schedule; confirm this with your stock plan administrator before your last day. For double-trigger RSU holders, the analysis adds a change-of-control dimension. Double-trigger RSUs have a service condition (time-based vesting) AND a change-of-control condition — both must be triggered for vesting to occur. If you are laid off during a pre-close period of a pending acquisition, the CIC trigger may fire at closing, potentially accelerating the entire unvested award. If you are laid off in a standard RIF with no CIC pending, the double-trigger operates identically to a single-trigger RSU: the service condition is never met after termination, unvested shares forfeit. Review your grant agreement for the definition of "change in control" and the timing requirements. Section 280G applies when executive separation is contingent on a CIC — if total contingent payments (including accelerated equity) reach 3x the executive's five-year average compensation, the excess becomes a non-deductible golden parachute subject to a 20% excise tax under § 4999. This primarily affects executives holding double-trigger RSUs or options that accelerate at a CIC-triggered layoff.

Equity at termination
Forfeited unvested: $100,000
ISO exercise window post-termination: 90 days
- By default, unvested RSUs are forfeited at termination unless a change-of-control acceleration clause applies.
- Negotiation lever: ask for pro-rata vesting of the next tranche, or full acceleration if part of a group layoff.
- ISO holders: you typically have 90 days post-termination to exercise vested ISOs before they convert to NSOs.
Action steps
- List every equity grant you hold and classify each as ISO, NSO, single-trigger RSU, or double-trigger RSU — the grant agreement and equity plan document specify the instrument type.
- For any ISO grants, confirm your last day of employment and mark the 90-day exercise deadline; failure to exercise converts ISOs to NSOs, permanently eliminating ISO tax treatment.
- For any NSO grants, read the grant agreement for the post-termination exercise window — it varies from 30 days to several years and is not set by statute.
- For unvested RSUs, identify which tranches vest within the next 90 days and negotiate to move the separation date past those vest dates, or ask for a cash payment equal to the near-term vesting value.
- If a change of control is pending or your layoff is part of an acquisition, confirm whether any double-trigger RSUs accelerate at closing and model the § 280G golden parachute implications if total contingent payments are large.
- Contact your stock plan administrator before your last day to confirm the settlement status of all vested RSUs and the exercise status of all vested options — do not assume these are automatically processed.
- Consult a CPA or tax advisor before the ISO exercise deadline; the combined strike-price cost plus AMT can be substantial, and post-separation planning must happen within the statutory window.
| Equity type | Forfeiture risk | Post-term action window | Tax timing | Cash required |
|---|---|---|---|---|
| ISO (Incentive Stock Option) | Unvested options forfeit; vested ISOs survive but must be exercised within 90 days or convert to NSO | 90 days from last day of employment per 26 U.S.C. § 422(a)(2) | No ordinary income at exercise; AMT preference item on spread per § 56(b)(3); gain taxed at long-term cap gain rates if holding periods met | Yes — must pay strike price plus potential AMT on the spread |
| NSO (Nonqualified Stock Option) | Unvested options forfeit; vested NSOs typically survive per grant agreement terms (often 30-90 days) | Per grant agreement — commonly 30–90 days post-termination | Ordinary income on spread at exercise (FMV minus strike price) per 26 CFR § 1.83-7; employer withholds supplemental wages | Yes — must pay strike price; tax on spread withheld at supplemental wage rate |
| Single-trigger RSU | Unvested RSUs forfeit at termination unless separation agreement provides acceleration; single trigger means vest on time only | No exercise required; shares settle automatically at vest if vesting continues. At layoff: forfeit unless negotiated | Ordinary income at vest equal to FMV of shares per 26 U.S.C. § 83(a); no cash required to acquire shares | No strike price; cash needed only for tax withholding on vest |
| Double-trigger RSU | First trigger: continued employment (time vest). Second trigger: change-of-control (CIC). At layoff without CIC: same as single-trigger. At layoff coinciding with a CIC: both triggers may fire, accelerating full vest | If CIC is pending or imminent, unvested double-trigger RSUs may accelerate at closing. Review grant agreement | Same as RSU: ordinary income at vest per § 83(a) | No strike price; withholding applies at supplemental wage rate at vest |
FAQ
- How do I know whether I have ISOs or NSOs?
- Your grant agreement will specify the option type. Look for "Incentive Stock Option" or "ISO" versus "Nonqualified Stock Option," "NQSO," or "Non-Statutory Stock Option." If you are unsure, your company's stock plan administrator or your brokerage (Carta, E*TRADE, Fidelity, Schwab) can tell you. The instrument type is also on the grant notice you should have received when the options were awarded.
- What happens if I hold both ISOs and NSOs?
- Each grant is analyzed independently. Your ISO grants have a 90-day post-termination exercise window under 26 U.S.C. § 422(a)(2); your NSO grants have whatever window your grant agreement specifies (which could be longer or shorter). Model the exercise decision for each grant separately: ISOs require AMT planning, NSOs require ordinary income recognition at exercise. Do not bundle them into a single decision.
- What is a double-trigger RSU and why does it matter at layoff?
- A double-trigger RSU has two vesting conditions: (1) continued employment through the time-based schedule, AND (2) a change-of-control event. Both must occur for vesting to happen. In a standard layoff with no acquisition pending, the service condition is unmet after termination and the RSUs forfeit — identical to single-trigger RSUs. If a CIC is pending when you are laid off, the second trigger may fire at closing, potentially accelerating your full unvested award. This is a significant negotiating point if your company is in the middle of an acquisition process.
- Do I have to exercise my options immediately when I am laid off?
- No — but your window is limited. ISO holders have 90 days from their last day of employment to exercise and preserve ISO status; after that window, unexercised ISOs convert to NSOs. NSO holders have whatever window the grant agreement specifies. You are not required to exercise on the day of separation. Use the window to model the AMT exposure (ISOs), assess the ordinary income tax (NSOs), and determine whether the post-exercise stock appreciation potential justifies the outlay.
- Is RSU forfeiture at layoff a clawback?
- No. RSU forfeiture is the lapse of a vesting condition — the shares were never delivered to you, so there is nothing to claw back. A clawback is a post-vesting recovery of shares or value already received. Under 26 U.S.C. § 83(a), unvested RSUs are subject to a substantial risk of forfeiture, so no income is recognized and no property changes hands until vesting. When employment ends before vesting, the condition simply fails; the employer does not recover something you had, it just never delivers something you were promised.
- If I have NSOs, should I exercise immediately at layoff before the window closes?
- Not necessarily. Exercising NSOs immediately triggers ordinary income on the spread in your layoff year. If your income is otherwise low in that year, the tax cost may be manageable. But if you just received a large severance, the additional income from NSO exercise could push you into a higher bracket. Compare the tax cost of exercising now against the risk that the post-termination window closes before you can exercise and the stock appreciates further. The window deadline is the binding constraint; make the exercise decision before then, not on the last day.
- How does Section 280G interact with equity acceleration at layoff?
- Section 280G only applies to payments contingent on a change in control. If you are laid off in a standard RIF, no CIC is involved and § 280G does not apply. If your layoff is part of an acquisition and your options or RSUs accelerate as a condition of the CIC, those accelerated payments are counted toward the 280G golden parachute threshold. If total CIC-contingent payments reach 3x your five-year average compensation, the excess over 1x your average is subject to a 20% excise tax on you and a lost deduction for the company. This matters most for executives with large unvested equity grants at the time of an acquisition.
