How to complete the Supplement B form

January 13, 2025

Supplement B (formerly known as Section 3) is an I-9 form that must be completed when one of the following occurs [1] :

• Your employee legally changes their name
• Your employee is rehired within 3 years of the date that their original I-9 form was completed
• Your employee’s documentation of employment authorization has expired

If your employee is rehired after 3 years of the date that their original I-9 form was completed, they will be required to complete a new I-9 form. Learn more in this article.

Supplement B Steps

To complete a Supplement B form, follow the steps below:

1. Click I-9 Center in the left sidebar.
2. Find the employee you need to complete Supplement B for and click Manage to the right of their name.
3. Click the More Actions button and then Supplement B.
4. Click either the Rehire staff or Change name tab based on the reason you are completing this Supplement B form.
5. Complete all required fields including your electronic signature.
6. Click Submit.

Important Note:

Supplement B forms do not need to be sent to E-Verify (for companies using E-Verify). Therefore, there are no further actions after the form is submitted [2]. The Fountain I-9 Center will save this form with the worker’s original I-9 form. Additionally, the I-9 Center audit trail for this worker will show a timestamped event for the Supplement B form being filed, including the name of the administrator who filled out and submitted the form. Access the audit trail by clicking More Actions and then Take Action on I-9.
