What is Form 3921?

Form 3921 is a tax form used by corporations to report exercises of incentive stock options (ISOs) to both the employee who exercised the ISO and the IRS.

The form provides details about the date of the option grant, the date the option was exercised, the exercise price, and the fair market value of the stock on the exercise date. This information is crucial for the employee to calculate their tax liability related to the ISO exercise.
