Selling Stock From Exercised NSOs: Taxes, Timing, and a Written Plan
NSO spread is taxed as ordinary income at exercise; only later growth can get capital gains rates. A written sale plan weighs cash needs against stock risk.
Selling Stock From Exercised NSOs: Taxes, Timing, and a Written Plan
1 / 7
How are NSOs taxed when you exercise and sell?
- At exercise, the spread between fair market value and strike price is ordinary income, reported on an employee's W-2 with tax withheld.
- Your cost basis in the shares becomes their fair market value on the exercise date.
- Any later gain or loss is capital: short-term if sold within a year of exercise, long-term if held longer.
- In a same-day exercise and sale, nearly all of the profit is taxed as ordinary income.

How are NSOs taxed when you exercise and sell?
- At exercise, the spread between fair market value and strike price is ordinary income, reported on an employee's W-2 with tax withheld.
- Your cost basis in the shares becomes their fair market value on the exercise date.
- Any later gain or loss is capital: short-term if sold within a year of exercise, long-term if held longer.
- In a same-day exercise and sale, nearly all of the profit is taxed as ordinary income.
Is there a tax reason to hold shares after exercise?
- The spread is taxed at exercise no matter what, so holding only affects gains that occur afterward.
- Post-exercise gains held more than a year qualify for federal rates of 0%, 15%, or 20%, plus 3.8% NIIT at higher incomes.
- California taxes capital gains as ordinary income, so the state-level benefit of waiting is nil.
- The trade-off is continued single-stock risk while you wait, which can outweigh the rate difference.
Could QSBS apply to shares from exercised NSOs?
- Shares acquired by exercising options can be qualified small business stock if the company met Section 1202 requirements when the shares were issued.
- The QSBS holding period starts at exercise, not at grant, so early exercise starts the clock sooner.
- For stock issued after July 4, 2025, the exclusion is 50% at 3 years, 75% at 4, and 100% at 5, capped at the greater of $15 million or 10x basis.
- Earlier stock generally needs five years and has a $10 million cap; California does not follow QSBS, so confirm eligibility with a CPA.
How do people set a selling target?
- Start with after-tax cash needs, such as a home down payment, a tax bill, or a cushion for a job change.
- Consider several price scenarios, including a steep drop, and weigh how likely each seems rather than treating them as equal.
- Identify the minimum amount you would want to have sold even if the price falls sharply.
- Judge outcomes by total net worth, not by whether you sold at the peak.
What selling methods are common?
- Scheduled sales, such as a fixed number of shares each month or quarter, spread timing risk over many prices.
- A ladder of limit orders at rising prices sells more as the stock climbs, but limit orders may never fill.
- Stop orders can execute well below the trigger price when a stock gaps down overnight.
- Employees subject to blackout windows often use a Rule 10b5-1 plan to pre-schedule sales.
What if your options are about to expire?
- NSOs usually expire 10 years after grant, and often about 90 days after you leave the company.
- Unexercised options that expire are simply lost, even if they are deep in the money.
- A cashless exercise-and-sell converts expiring options to cash without needing to fund the strike price.
- Check your grant agreement for the exact dates, since plans vary.
Key takeaways
- NSO spread is ordinary income at exercise; only later appreciation can qualify for capital gains rates.
- Holding after exercise is mainly an investment decision about single-stock risk.
- QSBS may apply to exercised shares, with rules that depend on the issue date.
- Base a selling plan on after-tax needs and realistic scenarios, and review taxes with a CPA.
