What Is Incentive Stock Options?
Incentive Stock Options (ISOs) are a special kind of stock option. They give an employee the right to purchase shares of company stock at a pre-determined price (often called the 'grant price' or 'exercise price') for a set period. What makes ISOs 'incentive' is their potential for favorable tax treatment. If certain conditions are met, the employee typically doesn't owe regular income tax when they exercise (buy) the stock. Instead, any gain is taxed at potentially lower long-term capital gains rates when they eventually sell the stock. This is a significant difference from Non-Qualified Stock Options (NSOs), where the 'bargain element' (the difference between the market price and exercise price) is taxed as ordinary income at exercise. The rules for ISOs are laid out in Internal Revenue Code (IRC) §422. Companies must design their stock option plans to meet these strict requirements for the options to qualify as ISOs. This often involves shareholder approval of the option plan and limits on the value of options that can become exercisable in any given year for an individual employee.
