FAQs
6039 Services ensure your company meets IRS Section 6039 requirements for stock plan reporting. This includes preparing, printing, mailing and filing Forms 3921 and 3922, validating your data, and submitting everything electronically to the IRS.
Any company that offers either:
- Incentive Stock Options (ISO)
- Employee Stock Purchase Plans (ESPP) qualified under Section 423
must file Form 3921 (ISO exercises) and Form 3922 (ESPP transfers/purchases).
Employee statements must be mailed by: January 31
IRS electronic filings must be completed by: March 31
If the date falls on a weekend/holiday, the deadline shifts to the next business day.
Yes. If you file 10 or more total information returns, the IRS requires e-filing starting in 2024. This threshold includes all returns your company files (W-2, 1099, 3921, 3922, etc.).
IRS penalties increase based on how late the filing is:
- $60 per form if filed within 30 days
- $120 per form if filed by Aug 1
- $310 per form after Aug 1
- Intentional disregard penalties start at $630 per form with no maximum
Late or incorrect employee statements can trigger additional penalties.

IRS filing extension (to file with the IRS):
Submit Form 8809 by the original due date to request an automatic 30-day extension.

Starting with 2024 filings, companies must now request an extension electronically using Form 8809 just like the IRS filing extension.
Summary of the new rule:
