Whether you quit, get the axe, or are blindsided by a layoff, what happens next could make or break your financial future. Play it wrong, and you risk losing a fortune—or getting hammered by taxes.
That’s why Summitry’s advisors (who specialize in Bay Area tech wealth) put together this no-fluff guide. Inside, you’ll learn exactly what to do when you leave your job—so you don’t leave money on the table.
Stock options are a critical component of compensation for many professionals, particularly in Silicon Valley and other competitive environments. These options typically vest over a predetermined schedule, commonly structured as a four-year plan with a one-year cliff.
This means employees must stay with the company for at least one year before any portion of
their options vest. After the cliff, vesting usually continues incrementally, often monthly or quarterly, until the full allocation is vested.
For employees who leave a company, the fate of their stock options depends on their vesting status. Vested options are those that employees have already earned and can retain, provided they exercise them within the company’s specified post-termination exercise (PTE) window (more on that later).
This window is typically 90 days for incentive stock options (ISOs) but may be longer for non-qualified stock options (NSOs) or at companies with more employee-friendly policies. If employees fail to exercise within this period they lose their vested options permanently.
Unvested options, on the other hand, are almost always forfeited upon termination or resignation. However, some companies, particularly in competitive industries, offer accelerated vesting under certain circumstances, such as layoffs, acquisitions, or change-of-control events. Accelerated vesting enables employees to gain immediate or faster access to their unvested stock options, allowing them to benefit from shares they otherwise would have lost. Instead of waiting for the standard vesting schedule to complete, a portion or all of the remaining unvested options become vested ahead of schedule.
There are two common types of accelerated vesting: single-trigger acceleration and double-trigger acceleration. Single-trigger acceleration occurs when a specific event, such as an acquisition or layoff, causes an immediate vesting of some or all unvested shares. This is more common in executive compensation packages and is designed to ensure employees are not left
empty-handed in the event of a sale or restructuring.
Double-trigger acceleration, on the other hand, requires two conditions to be met before unvested shares are accelerated. Typically, this means the company must first be acquired, and then the employee must be terminated within a specified period following the acquisition. Only when both conditions are satisfied will the unvested shares vest immediately.
Companies use accelerated vesting as both a retention incentive and a means to protect employees during acquisitions or layoffs. In a competitive job market, offering accelerated vesting can help attract and retain top talent, ensuring that employees do not lose out on a significant portion of their equity compensation in the event of unforeseen circumstances.
Employees anticipating a layoff or acquisition should review their stock option agreements carefully and consult with HR or a financial advisor to determine whether accelerated vesting applies and how to make the most of their stock options before making any career moves.

Now that you know what to do, let’s break down how to do it. The next section dives into your exercise options, the costs, and the strategies to keep more of your hard-earned equity.
You pay the exercise price and any applicable taxes out of pocket using your own funds. This method allows you to retain all the shares you exercise, maximizing potential future gains if the stock price rises. However, it requires sufficient cash upfront, which may be a financial burden, especially if the tax liability is high.
You use shares you already own to cover the cost of exercising your options, rather than paying in cash. Stock swaps allow you to avoid selling newly acquired shares, which can be beneficial if you expect the stock to appreciate. Note that this reduces your overall share count, meaning you give up potential future gains on the swapped shares. Additionally, if the swapped shares have appreciated significantly, you may trigger capital gains taxes.
You immediately sell a portion of your newly exercised shares to cover the exercise price and any tax obligations. Cashless exercise is convenient since it requires no upfront cash and allows you to capture gains while exercising your options. However, because you are selling a portion of the shares right away, you limit your long-term upside potential, especially if the stock price continues to rise after the exercise. This method is commonly used in public companies where shares can be sold easily on the open market.
Summary
Exercise Method | Pros | Cons |
---|---|---|
Cash Exercise | Maximize potential future gains | Significant upfront cost |
Stock Swap | Cover the cost with shares instead of cash when shares can’t be easily sold on the open market | Reduces overall share count; could trigger capital gains tax |
Cashless Exercise | No upfront cash required; common with publicly traded companies | Could limit long-term upside potential |
Ignoring the PTE deadline could result in losing valuable equity compensation, so check your stock option agreement as soon as you anticipate leaving.
If you leave on your own terms, standard PTE rules apply. You’ll need to exercise vested options within the designated timeframe, and unvested shares will be forfeited.
If you are laid off or terminated without cause, such as during company restructuring or downsizing, you may receive some leniency regarding your stock options. Some companies extend the PTE period as part of a severance package, giving you additional time to exercise vested options. In rare cases, severance agreements may also include continued vesting or accelerated vesting, allowing you to retain or immediately vest additional shares upon termination.
If you’re terminated for cause (e.g., misconduct, policy violations), companies often have the right to immediately revoke all vested and unvested stock options. This means you could walk away with nothing.
If you exercise ISOs within 90 days and hold the shares for at least one year from exercise and two years from the grant date, you qualify for long-term capital gains tax rates (typically lower than income tax rates).
However, exercising ISOs could trigger the AMT, which requires careful planning.
The spread between the exercise price and the fair market value (FMV) at exercise is considered income for AMT purposes, even though it’s not taxed for regular income tax. This “phantom income” can push you into AMT territory, potentially resulting in a significant tax bill without any actual cash received from selling shares.
An important consideration when exercising ISOs is the potential creation of an AMT credit. If your AMT calculation exceeds your ordinary income tax due to an ISO exercise, you generate an AMT credit. This credit can be carried forward indefinitely and used in future years when your regular tax liability exceeds your AMT liability.
For example, if your ISO exercise results in $40,000 more in AMT than your regular tax liability, you would generate a $40,000 AMT credit. In subsequent years, you can use this credit to offset your regular tax liability, but only to the extent that your regular tax exceeds what your AMT would have been.
This AMT credit mechanism helps balance out the tax impact of ISO exercises over time, potentially reducing your overall tax burden. However, it’s crucial to plan carefully, as the credit can only be utilized in years where your regular tax exceeds your calculated AMT.

NSOs are taxed at exercise as ordinary income based on the difference between the exercise price and the fair market value (FMV) of the stock. Additional taxes apply when you sell the shares, either as short-term capital gains (if held for less than a year) or long-term capital gains (if held for longer than a year). State-Specific Tax Considerations Tax treatment of stock options varies across states, which is particularly relevant for employees who have worked remotely or relocated.
Employees at public companies can generally exercise options and sell shares immediately for liquidity. Stock prices are determined by the market, and selling shares can be done through a brokerage account. However, employees should be aware of insider trading policies, blackout periods, and tax implications related to selling shares. Some companies also offer stock purchase plans or allow for stock swaps to optimize tax strategies.
For startups and pre-IPO companies, stock options may lack immediate liquidity. Exercising can be risky, as you may pay taxes on shares that you cannot yet sell. If the company eventually goes public or is acquired, the payout could be substantial—but if the company fails, you could lose your entire investment. The value of the shares is often determined by the company’s most recent valuation (409A valuation), which may fluctuate over time.
Background:
Jason, a product manager at a publicly traded company, decides to resign after four years to join a competitor. He holds 10,000 vested ISOs at a $5 strike price, which is the predetermined price at which he can buy the shares, regardless of the current market price of $50 per share. He has 90 days to exercise his options, or they will expire.
Action Steps:
Outcome:
Jason does a cash free exercise of his ISOs before the 90-day window closes, and plans to hold onto his stock for at least a year so that he can pay his tax at long-term capital gains rates. He avoids unnecessary taxes while ensuring he doesn’t lose valuable equity due to his resignation.
Stock options can be a goldmine—or a financial trap—depending on how you handle them. Play it smart, and they can fuel your long-term wealth. Ignore the fine print, and you could watch years of hard-earned equity vanish overnight.
If you’re leaving your company—by choice or not—you don’t have time to drag your feet. Deadlines are real. Tax traps are lurking. And every decision you make (or don’t make) can cost you tens of thousands, if not more. That’s why getting expert guidance is not optional—it’s essential.
