Does my company need to file Form 3921 with the IRS?
Forgetting Form 3921 is one of the biggest mistakes you can make. If your company transferred shares to any person(s) as a result of an Incentive Stock Option (ISO) exercise in the previous calendar year, then the company must file Form 3921 with the Internal Revenue Service during that calendar year. The deadlines are as follows:
1/31 - Deadline to furnish Copy B to all employees
2/28 - Deadline to paper file Copy A with the IRS
3/31 - Deadline to electronically file Copy A with IRS
As a Carta client, you will be able to generate form 3921 directly within the Carta platform in 'Form 3921' under the Compliance heading.
