What is Form 3921?

Every corporation that transfers a share of stock to a person during a calendar year in exchange for that person exercising an incentive stock option as defined in section 422(b) must submit Form 3921 for each transfer completed during that year. This form needs to be submitted for each employee who receives the share. 

The 3921 form is intended for informational purposes. Unless you sell the stock later, it is usually not recorded on your tax return. TaxBandits supports the e-filing of Form 3921 and employers required to file this form for the 2022 tax year can easily do so using our application.
