Purpose of Form 3921
TaxTC offers a secure and accurate way to file Form 3921 electronically.
Corporations file this form for each transfer of stock to any person pursuant to that person’s exercise of an incentive stock option described in section 422(b).
Note: A valid TTC (Transmitter Control Code) is required to use TaxTC’s products. TaxTC does not provide TTC. For information on how to obtain your TTC, visit the FAQ’s page on the IRS website.
