Stock options usually expire in 10 years. That means you’ll lose the right to buy those shares at the set strike price. And while it can be tempting to stick “stock option expiration date” in your calendar for 2036 and forget about it, you could be missing out on opportunities to exercise when the financial trade-offs look more favorable.
If you leave your company, for example, you may only have a short post-termination exercise window to exercise your vested stock options before they expire. Waiting can also get expensive: if your company’s value increases, we’ve seen taxes increase by over 9 times the expected amount.
That doesn’t mean you should automatically exercise every option before it expires.
Exercising means putting money into illiquid company stock, potentially with major tax costs and a risk that it loses value. Instead, use your stock option expiration date as a guideline you can plan around. Even if your deadline is approaching soon, there are still ways to figure out how to make the most of your options.
It’s a lot of information to wrap your head around, so we’re bringing it together in this guide.
We’ll cover:

While employee stock options commonly expire 10 years after the grant date, there are several situations when you might have a much earlier deadline to exercise.
For example, your options could be affected by:
In other words, seeing “2036” next to your stock option expiration date doesn’t necessarily mean you can safely forget about your options until 2036. Once the expiration date passes, you generally lose the right to buy those shares at your original strike price.
Start with your stock option grant agreement and equity plan documents. You may also be able to find your expiration date in the equity management platform your company uses, such as Shareworks or Carta.
Importantly, look for the original expiration date as well as the rules covering what happens if your employment ends. If anything is unclear, ask your company’s HR, legal, or equity administration team to confirm the terms of your grant.
If you’re considering leaving your company, try to check this before your last day. Knowing the deadline in advance gives you more time to understand what exercising would cost and decide what, if anything, you want to do with your vested options.
Your stock options may have a 10-year term from the grant date, but leaving your company can shorten that exercise window dramatically. It can feel painful to let stock options you spent years earning disappear, but that doesn’t automatically make exercising the better financial decision.
When you exercise, you’re choosing to invest your own money in company shares. If your company is still private, you may not be able to sell those shares for years, and there’s no guarantee they’ll ultimately be worth more than you paid.
Before you exercise stock options, consider the following.
Start by comparing your strike price, which is what you’ll pay per share to exercise, with the current fair market value (FMV) of your company’s common stock.
If the FMV is higher than your strike price, your options are in the money. For example, an option with a $5 strike price when the shares have an FMV of $15 has a $10 spread. That means that if you exercise, the stocks are immediately worth more than what you paid for them. However, you may also have to pay tax on that positive spread.
If the FMV is below your strike price, your options are underwater. Exercising would mean paying more for the shares than they’re currently worth.
Being in the money doesn’t necessarily mean you should exercise, and being underwater doesn’t tell you what the company will be worth in the future. But understanding where your options stand today gives you a useful starting point.
Multiply the number of options you want to exercise by your strike price to calculate the basic exercise cost.
But don’t stop there. Both incentive stock options (ISOs) and non-qualified stock options (NSOs) can create tax consequences when you exercise, although they’re taxed differently. That can turn what looked like an affordable exercise into a much larger financial commitment.
One figure to pay attention to is the spread, or the difference between your strike price and the FMV when you exercise. For NSOs, that spread is generally taxed as ordinary income at exercise. For ISOs, it generally isn’t regular taxable income at exercise, but it can count toward your alternative minimum tax (AMT) calculation if you hold the shares.
Because that spread can change as your company’s FMV changes, when and how much you exercise can affect your tax exposure. Depending on your situation, exercising only a portion of your options or spreading exercises across multiple tax years may help manage the potential tax cost.
At Secfi, we help startup employees and executives understand and act on their equity. We built Maeve, a free AI equity assistant, to help you figure out equity questions like how much it could cost to exercise.

Think about exercising the same way you would think about making any other investment.
Financing may also be an option if you don’t want to spend the upfront cash to exercise. Options include traditional loans, which typically require repayment, and non-recourse financing, which doesn’t require monthly payments or borrowing against personal assets. In both cases, qualifying can depend on your company’s stage in addition to your personal situation.
Letting unexercised stock options expire generally doesn’t create a tax bill because you haven’t purchased the shares or realized income from them.
But if an approaching expiration date prompts you to exercise, taxes can become an important part of the decision. We sometimes call this the “surprise factor”, because many of our clients find their exercise costs 8x–10x more than they expect when they take taxes into account.
The tax treatment depends partly on whether you have incentive stock options (ISOs) or non-qualified stock options (NSOs).
Exercising ISOs generally doesn’t create ordinary taxable income for federal regular income tax purposes at exercise. However, if you exercise your ISOs and continue holding the shares through the end of the calendar year, the difference between your strike price and FMV at exercise is generally included as income for AMT purposes.
AMT is a parallel federal tax system that uses different rules to calculate taxable income. You calculate your taxes under both the regular income tax system and AMT rules, then generally pay whichever amount is higher. Having to pay the higher alternative minimum tax is what’s known as “triggering AMT”.
For ISO holders, the spread at exercise can increase your income for AMT purposes, potentially resulting in a big tax bill even though you haven’t sold your shares or received any cash from them.
Here’s an example, but remember to talk to a tax professional about your own situation. Say you exercise 10,000 ISOs with a $2 strike price when the FMV is $10. You’d pay $20,000 to exercise your options, creating an $80,000 spread for AMT purposes.
That doesn’t mean you automatically owe tax on that $80,000 at a particular rate. Your actual AMT depends on the rest of your income, deductions, filing status, and other factors. But if the exercise pushes you into AMT, you could owe thousands or even tens of thousands of dollars in additional federal tax, on top of the $20,000 you already paid to exercise.
There are a few other ISO timing rules to keep in mind when deciding whether and when to exercise:
With NSOs, the spread between your strike price and the FMV of the shares at exercise is generally treated as ordinary compensation income at your ordinary income rate. If you live in California, that can be as high as 50%.
So if your NSOs are significantly in the money when they’re approaching expiration, the tax cost could be substantial on top of what you pay to exercise the shares.
This is also why waiting until close to your expiration date can change the economics of your exercise. If your company’s FMV increases over time, the spread may grow with it, potentially increasing the tax cost of exercising.
Of course, the opposite can happen too. Private-company valuations can fall, and there’s no guarantee that exercising earlier will produce a better financial or tax outcome.
The important part is knowing your expiration date early enough to model these scenarios before the deadline makes the decision for you.
Secfi provides liquidity and wealth management services to help employees and executives of innovative companies achieve their financial goals. As of July 2026, more than 62,000 people have used Secfi and our tools to help them make decisions about their stock options.
Whether your stock option expiration date is years away or you’re already facing a short deadline, Secfi can help you understand and model your next steps.
Here’s why employees and executives at companies including Google, Gusto, and Databricks work with Secfi.
Maeve is Secfi’s AI built specifically for private-company equity. You can connect your Carta account or enter your grant details manually, then ask questions using your own equity information.
For example, if your options are approaching expiration, you could ask Maeve:
Instead of piecing together your grant details, tax rules, and different scenarios across multiple searches and spreadsheets, you can use Maeve to organize that information and explore the trade-offs in one place.
For illustrative purposes only. Actual results may vary, and there is no guarantee of any particular outcome.
If you already use an AI assistant such as ChatGPT, you can also connect to your Secfi data through the Secfi MCP. Not only will you access any of your existing data that you’ve added to Maeve, but you’ll also be able to use our calculation engines directly inside of the LLM you already use.
That can make a big difference because without an added calculator like those we’ve developed at Secfi, standard LLMs often make mistakes and change their answers without any explanation. If you’re trying to figure out your financial situation, small AI errors along the way can make a big difference when modeling scenarios.
Both Maeve and our MCP let you check our calculations so you can confirm they’re based on reasonable assumptions and not AI hallucinations.
An approaching stock option expiration date can affect your broader life and finances.
You may be deciding whether to put savings into your company, how an exercise could affect your taxes, or whether keeping more cash available would better support goals such as buying a home, investing elsewhere, or preparing to leave your job.
Secfi Wealth gives you access to financial advisors who specialize in private-company equity. They can help you consider your stock options alongside the rest of your financial life and goals.
Instead of looking only at whether you can afford to exercise before your options expire, our advisors help you think through how much you’re comfortable investing based on your financial situation, and what different exercise scenarios could mean over time.
AMT alone has many implications, and most financial advisors will never need to advise on how to calculate or help minimize its impact. The Wealth team doesn’t work on commissions, and they have a fiduciary duty to advise what makes the most sense for you.

Even if you decide you want to exercise before your stock options expire, the cost can still be a barrier.
For eligible employees, Secfi offers non-recourse financing that may help cover the cost of exercising stock options and associated taxes without requiring you to put unrelated personal assets on the line. The financing is tied to your stock options and the resulting shares instead.
Unlike a traditional loan, repayment is tied to the terms of the financing agreement and a future liquidity event. And because there’s no monthly loan payment, the financing generally won’t increase your debt-to-income ratio in the same way as traditional debt, which can help when applying for a mortgage or other lines of credit.
Eligibility for non-recourse financing depends on factors including your company and equity, so it isn’t available for every stock option holder. Secfi is highly selective, and typically only works with later-stage startups who are closer to an IPO.
Financing also doesn’t make exercising automatically worthwhile. You still need to consider the company’s prospects, the value of your options, the terms and cost of financing, and how much risk you’re comfortable taking before deciding whether to exercise.
Dan Sinner had spent nearly a decade helping build Happy Money as a founding team member and Chief Customer Officer when his own stock options started approaching a hard expiration deadline.
Even with years of startup experience, deciding what to do wasn’t straightforward.
“As an executive, we're supposed to know all the things about all the things, which is not necessarily true,” Dan said. “Especially when it comes down to the complexity of taxes and different types of equity.”
Cost was another concern. Dan had recently gotten married and wanted to buy a house, and he described himself as relatively risk-averse with his personal finances. Paying to exercise his options out of pocket wasn’t an attractive choice.
Secfi helped Dan understand his equity situation and provided non-recourse financing to exercise his options. But his experience also made him think about the employees at Happy Money who might have even less support navigating their equity.
Happy Money ultimately partnered with Secfi to give employees across the company access to equity education and financing options. Dan wanted that support to start much earlier than his own had.
“I'd rather tell employees on the day they get their offer, ‘Here's your partnership with Secfi for you to consider after your 12-month cliff,’” he said.
For Dan, part of the value was giving employees somewhere to turn beyond scattered online resources or simply telling them to hire a CPA. He wanted employees at every level to understand their choices before years of earned equity potentially disappeared.

Your stock option expiration date may be years away, or it could suddenly become much closer if you leave your company. Either way, knowing the deadline early gives you more time to understand your choices.
You don’t have to figure it out alone. Use Maeve or Secfi’s MCP to explore different scenarios before your expiration date, or speak with our team directly if you want support figuring out your equity.
When an employee stock option expires, you generally lose the right to exercise it and buy the underlying shares at your strike price. If the option was in the money, that can mean giving up potential intrinsic value. If it was underwater, letting it expire may be less painful, since the strike price was already above the current fair market value.
That’s why it helps to review your stock option expiration date early. If exercising makes sense for your situation, you may need time to plan for the exercise cost, taxes, and the fact that private-company shares can remain illiquid for years. Working with a specialist advisor like the team at Secfi Wealth or our free AI equity assistant Maeve can help you make a plan before your stock options expire.
For employee stock options, the expiry date or expiration date is the final date you can exercise your vested options under the terms of your grant. Many employee stock options have a term of up to 10 years from the grant date, but leaving your company can trigger a much shorter post-termination exercise window.
Your actual options expiration date should be listed in your grant agreement or equity platform. If you’re unsure which deadline applies, confirm it with your company before making an exercise decision.
If you mean employee stock options, there is no universal 2026 expiration calendar. Your expiration date depends on your individual grant, company plan, grant date, and whether an event such as leaving your employer changes your exercise window.
If you mean exchange-traded options contracts, standard monthly equity options generally expire on the third Friday of the expiration month.
No. A 10-year term is common for employee stock options, but not every grant lasts that long, and you may face an earlier expiration date if you leave your company.
Your company’s equity plan can also set different rules for different grants or employees. Some companies offer extended post-termination exercise periods, while others use shorter windows. Always check your own grant documents rather than assuming the 10-year rule applies. You can use Secfi’s AI equity assistant, Maeve, to plan different scenarios based on your stock options expiration date.
No. Employee stock options are equity compensation granted by your employer, while exchange-traded options contracts are securities used in options trading.
Exchange-traded call options and put options have standardized expiration cycles, which can include monthly contracts, weekly options, and other expiries tied to the underlying stock or index. Terms such as expiration month, last trading day, time value, short position, OCC, and The Options Clearing Corporation generally relate to traded options rather than employee equity options. Standard monthly contracts are often associated with the third Friday of the month, although weekly expiries and some index options follow different schedules.
For an employee, the dates that matter are the ones in your stock option grant and company plan, particularly your original expiration date and any post-termination exercise deadline.
