What it means
An option gives someone the right, but not the obligation, to buy a set number of shares at a set price, known as the exercise or strike price. Options normally vest over time, so a four-year grant with a one-year cliff gives the holder nothing until their first anniversary and then a portion each month afterwards.
What makes an option non-qualified is simply that it sits outside the narrow statutory category of incentive stock options. Because it is outside that category, the company faces fewer restrictions on who receives it, how large the grant is and how long it lasts.
The tax moment that catches people out is exercise, not sale. On the day the option is exercised, the spread between market value and strike price is treated as employment income, subject to income tax and payroll withholding, even if the holder has not sold a single share.
That creates a real cash problem in a private company where the shares cannot easily be sold. The holder must find cash for the exercise price and the tax bill on a paper gain, which is why many people wait for a liquidity event or use a cashless exercise where enough shares are sold immediately to cover both.
From the company's side, non-qualified options generate a corporation tax deduction equal to the income the holder recognises, which incentive stock options generally do not. Finance teams also record a share-based payment expense over the vesting period based on the option's fair value at grant, so the profit and loss impact starts long before anyone exercises.
In practice
Real-world examples.
Example
A software company grants 50,000 non-qualified options to a non-executive director. Because directors are not employees, incentive stock options are not available, and the non-qualified form is the only workable route.
Example
A sales manager exercises 8,000 options at a $2.50 strike when the shares trade at $12.50. He uses a cashless exercise, selling enough shares at once to cover the $20,000 exercise cost and the tax on the $80,000 spread, and keeps the balance in shares.
Example
A private manufacturer approaching a sale advises option holders to exercise early, while the valuation is still low, so that most of the future gain is taxed as a capital gain rather than as employment income. The finance team models the cash cost for each holder before recommending it.
Think of it
“NSO is a regular stock option-taxed as ordinary income at exercise.
Formula
Calculation
Bargain element (ordinary income at exercise) = (Market value per share at exercise - Exercise price) x Number of shares
An employee holds 10,000 vested non-qualified options with an exercise price of $4.00 per share. She exercises when the shares are worth $19.00 each.
Cost to exercise = 10,000 x $4.00 = $40,000.
Market value of the shares received = 10,000 x $19.00 = $190,000.
Bargain element = ($19.00 - $4.00) x 10,000 = $150,000 of ordinary income.
If her combined income and payroll withholding rate is 40%, the tax due at exercise is $150,000 x 40% = $60,000. Her cost basis in the shares becomes the full $190,000 market value.
She sells two years later at $26.00 per share for proceeds of 10,000 x $26.00 = $260,000. The capital gain is $260,000 - $190,000 = $70,000, taxed under capital gains rules rather than as employment income.Case study
Seen in the real world.
Bramble Logistics Technologies is a fictional, illustrative freight software business that granted non-qualified options generously to early hires and to a group of external advisers. Nobody in the company had modelled what would happen at exercise, because the shares had no market and the options felt like a promise rather than an asset.
In this illustrative example a strategic investor bought a minority stake, which reset the share valuation from $1.00 to $16.00. Twelve employees held 200,000 options at a $1.00 strike, giving a combined bargain element of ($16.00 - $1.00) x 200,000 = $3,000,000 and a withholding obligation of roughly $1,200,000 at a 40% rate.
Bramble had not budgeted a cent for it. The company negotiated a partial secondary sale into the funding round so that option holders could sell some shares for cash and meet their tax bills, and it added a standing rule that every future grant is reviewed against a modelled exit valuation. The illustrative point is that share options are a payroll event waiting to happen, not merely a line in an offer letter.
Watch out
Common mistakes.
- Thinking tax is only due when the shares are sold. For non-qualified options the taxable event is exercise, regardless of whether any shares are sold.
- Forgetting to reset the cost basis after exercise. The basis becomes the full market value at exercise, and using the strike price instead means paying tax twice on the same gain.
- Assuming an option is worthless because the current share price sits below the strike. Options normally have years to run, and a share price below the strike today says nothing about the position at expiry.
Questions
People also ask.
What is the main difference from an incentive stock option?
Incentive stock options can defer tax until sale and offer capital gains treatment if holding rules are met, but they are restricted to employees and capped in value.
Can a company grant non-qualified options to a contractor?
Yes, and this flexibility is one of the main reasons companies use them for advisers, consultants and non-executive directors.
What happens to unexercised options if someone leaves?
Most plans give a short post-termination window, often 90 days, after which vested options lapse, so leavers should model the exercise cost early.
