Some American employers offer stock options as part of an employee compensation package. These benefits can give workers an opportunity to purchase company shares at a predetermined price, potentially allowing them to benefit if the stock rises.
But stock options are not the same as receiving shares outright. Their value depends on the company's share price, the option terms, and the employee's ability to exercise them.
What is an employee stock option?
An employee stock option gives the employee the right to buy a specified number of company shares at a set exercise price, subject to the award agreement.
For example, a worker might receive options to buy 1,000 shares at $20 each. If the stock later trades at $35, the options may have an apparent spread of $15 per share before taxes, fees, and other considerations.
If the share price remains below the exercise price, the options may have no immediate exercise value.
Incentive stock options
Incentive stock options, or ISOs, may receive special federal tax treatment if statutory requirements are met. Generally, there is no regular federal income inclusion merely when an ISO is granted or exercised, although exercising ISOs can create alternative minimum tax considerations.
The eventual sale of the shares can affect whether the transaction qualifies for favorable capital gains treatment. Holding-period requirements matter.
Nonqualified stock options
Nonqualified stock options, often called NSOs or NQSOs, are generally taxed differently. When an employee exercises a nonqualified option, the difference between the fair market value of the shares and the exercise price is generally treated as compensation income.
A later sale may produce a capital gain or loss based on the employee's adjusted basis and the sale price.
Check the award agreement
Employees should review the vesting schedule, expiration date, exercise price, post-employment exercise window, and restrictions on selling shares. Leaving a company can create a deadline to exercise vested options, and missing it may cause the options to expire.
Workers should also consider concentration risk. Having both employment income and a large investment in the same company can expose a household to the same business risk from two directions.
Bottom line: Employee stock options can be valuable, but their tax treatment and deadlines differ by type. Understand the award terms and potential tax consequences before exercising or selling shares.
