An incentive stock option and a nonqualified stock option do not follow identical federal tax rules. The tax result may depend on the option type, exercise price, value at exercise, sale date, and holding period.

An ISO exercise can create an alternative-minimum-tax issue even without a sale generating cash to pay the tax. A nonqualified option can involve wage reporting, followed by a separate gain-or-loss calculation when shares are sold.

Before a large exercise, request a tax projection rather than relying only on the employer's withholding. Preserve grant agreements, exercise records, Forms 3921 when applicable, and sale information. Cash-flow risk is part of the decision, particularly when shares cannot readily be sold.

Your next steps

• Identify whether each grant is ISO or nonqualified.
• Model exercise and sale dates before acting.
• Keep employer, payroll, and brokerage records together.
