Form 3921 is an IRS form that reports the exercise of an employee Incentive Stock Option (ISO). It is an informational form only. It is generally not entered on your tax return unless you then sold the stock, or if you could be subject to alternative minimum tax (AMT). 

 

For more details, here is a help article on Incentive Stock Options.
