Title: Non‑Qualified Stock Options (NSOs) — What they are, how they’re taxed, and practical steps for employees
Key takeaways
– A non‑qualified stock option (NSO) gives the holder the right to buy company shares at a preset exercise (strike) price for a defined period.
– NSOs create ordinary income at exercise equal to (FMV at exercise − exercise price). That income is reported on your W‑2 (or 1099 for non‑employees) and subject to income and payroll taxes.
– Your cost basis in the shares after exercise is the FMV at exercise; subsequent gains or losses on sale are capital gains/losses measured from that basis.
– NSOs are simpler and more common than incentive stock options (ISOs) but do not receive ISO tax treatment (no AMT preference item from the option itself).
– Decide whether and when to exercise based on stock price, taxes, cash needs, diversification, vesting and post‑termination exercise windows—consult a tax advisor.
What is an NSO?
– Definition: An employer grants the holder the right to purchase a specified number of company shares at a fixed price (exercise price) during a set timeframe.
– Purpose: Used as compensation and to align employees’ incentives with company performance. Frequently used by startups and private companies when cash is limited.
– Vesting and expiration: Options usually vest over time (e.g., 4 years, 1‑year cliff) and expire after a defined period (commonly 7–10 years). Leaving the employer often shortens the time you have to exercise (commonly 90 days, but this varies).
Tax treatment — simple explanation
1. At grant: Generally no taxable event for typical NSOs if the exercise price equals FMV at grant.
2. At exercise: Taxable event — ordinary compensation income = (FMV at exercise − exercise price) × number of shares.
– This amount is treated as wages and reported on your W‑2 (for employees) and is subject to federal/state income tax withholding and payroll taxes (Social Security and Medicare) or reported on a 1099 for non‑employees.
3. After exercise (sale of shares): When you sell the shares, you recognize capital gain or loss equal to (sale price − basis). Your basis is the FMV at exercise (i.e., the amount on which you already paid ordinary income tax).
– Holding period for capital gains begins the day after exercise. Sold within 1 year = short‑term (taxed as ordinary income); held >1 year = long‑term (lower rates).

Numeric example
– Grant: 1,000 NSOs, exercise price = $5.
– You exercise when FMV = $20.
– Ordinary income at exercise = (20 − 5) × 1,000 = $15,000. This amount appears on your W‑2 as wages.
– Cost basis in the shares = FMV at exercise = $20 × 1,000 = $20,000 (this equals exercise price paid $5,000 + $15,000 income).
– If you immediately sell at $20, there is no capital gain or loss (sale price = basis). If later sell at $25, capital gain = (25 − 20) × 1,000 = $5,000 (short‑ or long‑term depending on holding period).
Practical steps: before accepting NSOs
1. Understand the terms: number of options, exercise price, vesting schedule, expiration, post‑termination exercise window, repricing/clawback provisions and any change‑of‑control treatment.
2. Determine grant price relative to arm’s‑length FMV (for private companies, check the company’s 409A valuation). If the strike is below current FMV, you could owe immediate tax at grant or exercise—ask HR/finance.
3. Estimate potential value: calculate several scenarios (flat stock, moderate growth, big growth) and what the net after taxes might be.
4. Consider allocation: compare the options’ potential upside with the alternative (higher salary, bonus, or different equity like RSUs/ISOs).
5. Get tax and legal counsel for complex situations (early exercise, 83(b) elections, non‑employee awards).
When to exercise — practical checklist
Consider exercising when:
– The market price (or an expected future price) is comfortably above the exercise price, creating intrinsic value.
– You can afford the exercise cost and associated tax withholding (or have a plan to fund them).
– You want to start the capital‑gains holding period (if you expect long‑term gains and lower capital gains tax).
– You are comfortable concentrating some net worth in your employer’s equity (diversification risk).
Avoid exercising if:
– The stock price is below or near the strike (“underwater” options).
– You can’t afford both the cash exercise price and the tax hit.
– Post‑termination exercise window is short and you cannot exercise before losing rights.
How to exercise — public company vs private company
Public company
1. Cash exercise: pay exercise price and hold shares. You’ll owe ordinary income taxes at exercise and broker/issuer may withhold or require estimated tax payments.
2. Cashless/sell‑to‑cover: broker sells enough shares immediately to cover exercise price and taxes, delivering net shares or cash to you. This avoids needing upfront cash.
3. Broker-assisted exercise: use your brokerage account online or submit form to plan administrator.
Private company
1. Prepare cash: private companies may require full cash payment to exercise and may not permit cashless exercises.
2. Plan for taxes: you’ll still owe ordinary income tax at exercise; the company will typically report wage income if you’re an employee. If the company is illiquid, you may need to pay taxes without having a market to sell shares—plan funding (savings, loans, secondary markets).
3. Consider early exercise/83(b): some startups allow early exercise of unvested options to acquire restricted stock. If so, an 83(b) election can enable taxation at the low initial FMV (file within 30 days). This is complex and requires legal/tax advice.
Tax reporting and record keeping — practical steps
– Keep records: grant agreements, vesting schedules, exercise confirmations, broker statements showing FMV at exercise and any shares sold.
– Employer reporting: the ordinary income portion should appear on your W‑2; verify amounts match your records.
– File capital gains: report gains/losses from share sales on Schedule D/Form 8949. For employees of private companies, if your employer didn’t withhold, you may need to make estimated tax payments to avoid penalties.
– Retain 409A valuations, especially for private company exercises, in case the IRS questions FMV at exercise.
Payroll withholding and taxes to budget for
– Ordinary income at exercise is subject to federal income tax and payroll taxes (Social Security and Medicare) — expect both withholding and employer payroll tax reporting on the W‑2.
– If employer withholding is insufficient or none is taken at exercise, you may owe additional tax at year‑end or need to make estimated tax payments.
Pros and cons of NSOs
Pros
– Potential for substantial upside if company stock appreciates.
– Flexible design — can be granted to employees, consultants and non‑employees.
– Simpler recordkeeping than ISOs for employers.
Cons
– Immediate ordinary income tax when you exercise (could be large).
– Risk of illiquidity for private company shares; you may owe taxes before you can sell.
– Concentration risk—your job and a portion of your net worth may depend on the same company.
Should you accept NSOs as part of compensation?
Ask these questions:
– How confident are you in the company’s growth prospects?
– What percentage of the company do the options represent (absolute value vs percentage of your compensation)?
– Will accepting options reduce cash compensation you need for living expenses?
– How soon and how likely will there be liquidity to convert shares to cash?
If the company’s upside is high and you can tolerate risk, NSOs can be valuable. If you need steady cash or the company’s prospects are uncertain, negotiate for more salary or a different equity vehicle.
Practical decision steps (before exercising)
1. Run after‑tax scenarios for your marginal tax bracket: immediate exercise + hold vs wait and sell‑to‑cover at exercise vs wait until sale.
2. Confirm whether the company will withhold taxes or you must pay estimated taxes.
3. If private, check for secondary markets or company buyback policies to fund taxes/cash needs.
4. Consider diversification: if the exercised shares would be a large share of your net worth, consider selling some (if allowed) once liquid to reduce concentration.
5. Consult a tax advisor or CPA, especially for large exercises or early exercises with 83(b) considerations.
Common pitfalls to avoid
– Underestimating the tax bill at exercise.
– Not checking post‑termination exercise windows — you can lose options after leaving.
– Failing to document FMV at exercise for later tax basis calculations.
– Exercising large amounts without a plan to fund taxes or diversify.
Bottom line
NSOs can be valuable compensation, but they create ordinary income at exercise and require careful tax, cash‑flow and liquidity planning. Evaluate the option terms, estimate after‑tax outcomes under multiple scenarios, and consult tax/legal advisors before exercising large positions or making 83(b) elections (if applicable).
