Who needs to file a Form 3921?

Form 3921 is a tax form that is required whenever an employee exercises an incentive stock option ("ISO"). For ISO exercises that occurred in 2022, employers must provide their employees (or former employees) copies of the associated Form 3921s no later than January 31, 2023.

In addition to distributing Form 3921s to employees who exercised ISOs, a company needs to file Form 3921 with the IRS. Failure to do so in a timely fashion could result in significant tax penalties. However, Form 3921s are not required for employees who are nonresident aliens or with respect to exercises of non-qualified stock option grants.

What are the deadlines for filing for the 2022 tax year?

  • January 31, 2023 - Furnish copies of Form 3921 to relevant employees.

  • February 28, 2023 - Paper filing of Form 3921.

  • March 31, 2023 - Electronic filing of Form 3921.
