A stock option is not cash. It's not stock.
It's the right to purchase stock at a fixed price in the future. Whether that right is worth anything depends entirely on the difference between your strike price and the future value of the company — which is why understanding how options work, the tax implications, and what questions to ask your employer are essential for any startup employee who wants to evaluate their equity package honestly.
This guide is written for employees — not founders — who want to understand what they actually have.
When your employer grants you stock options, they're giving you the right to buy a specific number of shares at a specific price (the strike price or exercise price) at some point in the future.
The strike price is set at or near the fair market value (FMV) of the company's common stock on the date of the grant. That fair market value is established through a 409A valuation — an independent appraisal the company commissions, typically annually or after major funding events.
If the company grows and the stock becomes worth more than your strike price, you can exercise your options (buy the shares at your strike price) and potentially sell them for a profit. If the company never reaches a value above your strike price — or never has a liquidity event (acquisition, IPO) — your options may expire worthless.
The options themselves are not value. The spread between your strike price and the future share price is value — if it materializes.
Options don't all become available to you immediately. They vest over time according to a schedule.
Standard vesting: 4-year vesting with a 1-year cliff. No options vest in the first year. At the 1-year mark (the cliff), 25% vests. The remaining 75% vests monthly or quarterly over the following three years.
Why vesting exists: It aligns your interests with the company's. If you leave after six months, unvested options aren't yours. If you stay for four years, you've earned the full grant.
Acceleration: Some grants include acceleration provisions — clauses that cause unvested options to vest early if specific events occur (acquisition, termination without cause). Know whether your grant has these before you sign.
There are two types of stock options. The distinction matters enormously for taxes.
The practical difference: ISOs offer better tax treatment but come with complexity and AMT risk. NSOs are simpler but create immediate taxable income at exercise.
When you exercise ISOs, the spread between your strike price and the FMV at exercise is an AMT (Alternative Minimum Tax) preference item. This means:
AMT exposure from ISO exercises is a real risk that has caught startup employees off guard, particularly after market downturns. The specific impact depends on your individual tax situation, the size of the spread, and your total income. Consult a qualified tax professional before exercising a large ISO grant. Do not rely on general guidance alone.
Some companies allow early exercise: you can exercise options before they're fully vested. This is different from standard post-vesting exercise.
The 83(b) election applies specifically to early exercise. It allows you to elect to be taxed on the spread at the time of exercise, rather than as shares vest over time.
Why it matters for early exercise: If you early-exercise immediately after receiving your grant, when FMV equals your strike price, the spread is zero — meaning a zero-tax event. The capital gains clock starts immediately from that date, and future appreciation is taxed at capital gains rates rather than ordinary income rates.
Critical point: The 83(b) election must be filed with the IRS within 30 days of exercise. Miss the deadline and you lose the election permanently.
What the 83(b) does NOT do: It does not apply to standard post-vesting exercise of ISOs or NSOs. If you're exercising fully vested options in the ordinary course, the 83(b) is not relevant to your situation.
When you leave a company — voluntarily or involuntarily — you typically have 90 days to exercise your vested options. After that window closes, the options expire worthless.
This creates a critical decision at departure: do you exercise your vested options before you leave?
Factors to evaluate:
Some companies offer extended exercise windows (1–10 years post-departure) as an employee-friendly policy. Ask before you sign.
When a company is acquired, investors with preferred stock are typically paid first — before common stockholders (which includes employees who've exercised options).
1x liquidation preference (standard): Preferred shareholders receive their investment back before any common stockholder is paid. After that, remaining proceeds are distributed pro-rata.
Participating preferred: Preferred shareholders get their investment back AND participate in remaining proceeds proportionally. More dilutive to common shareholders.
In a below-expectations exit, preferred liquidation preferences can consume all of the exit proceeds — leaving common shareholders (your exercised options) with nothing, even if the company sold for a positive number.
The implication: The acquisition price alone doesn't tell you how much your options are worth. What matters is the acquisition price minus all liquidation preferences, divided by fully diluted shares, compared to your strike price. See our startup equity guide and equity dilution guide for how dilution compounds over time.
The answers to these questions require your employer to share information about the company's cap table and financial structure. Many will share these details with prospective employees — and your comfort with the answers should inform how much weight you give the equity portion of your offer.
Employees who don't ask these questions often don't know whether their equity is meaningful until an exit happens — by which point it's too late to renegotiate.
Don't count unvested options as current compensation. You have the right to earn them — if you stay, the company succeeds, and you meet the vesting schedule. Treating unvested equity as money you have now leads to undervaluing salary, staying at a job longer than makes sense, or making financial plans based on equity that may never vest.
Don't assume options offset a below-market salary. Equity is speculative. Salary is certain. A 20% salary cut for "more equity" is only rational if the equity returns more than the cumulative salary reduction. Most startup options expire worthless — not because startups are a scam, but because most startups don't produce exits, and many that do produce exits below expectations.
Don't neglect exercise cost and taxes before you leave. Run the numbers before you resign. If exercising all your vested options costs $15,000 plus a potential five-figure tax bill, and you don't have that cash, you need to know before you're on a 90-day clock.
Employee stock options can be genuinely valuable — but the gap between "I have options" and "I have meaningful compensation" is wide, and it's filled with vesting schedules, tax complexity, exercise windows, liquidation preferences, and uncertain company outcomes.
The employees who navigate equity well are the ones who understand what they actually have, ask the right questions before signing, and get professional advice before making exercise timing decisions. The ones who get hurt treated options like guaranteed cash and were surprised by the mechanics.
Understand the vesting. Know the difference between ISOs and NSOs. Take AMT risk seriously. Ask the seven questions. If you're making a significant exercise decision, work with a tax professional first.
