Mastering the I-9 Process for Rehires and Compliance
When it comes to the i-9 process for rehires, the most important tool in your arsenal is Supplement B, formerly known as Section 3. This specific part of the form is designed to handle those “welcome back” moments and ensure your records stay current without forcing everyone to start from scratch. However, a common point of confusion for many HR professionals is the difference between a rehire and a reverification.
A rehire occurs when an individual who previously worked for your company returns after a formal separation of service. Reverification, on the other hand, is the process of confirming that an employee’s temporary work authorization is still valid, regardless of whether they ever left the company. You might find yourself doing both at the same time if a returning employee’s work authorization expired while they were away.
Maintaining I-9 compliance requires a keen eye for these distinctions. If you simply update a rehire date but fail to reverify an expired Employment Authorization Document (EAD), you are technically employing someone without verified authorization, which is a major red flag during audits.
Here is a quick look at how these requirements differ:
| Feature | Rehire Process | Reverification Process |
|---|---|---|
| Trigger | Employee returns after a break in service | Work authorization is about to expire |
| Timing | Must be done by the first day of work | Must be done before the expiration date |
| Form Used | Supplement B (if within 3 years) | Supplement B |
| Documents | May not need documents if authorization is valid | Always requires List A or List C documents |
| Identity (List B) | Never reverify List B documents | Never reverify List B documents |
Step-by-Step Guide to the I-9 Process for Rehires
If you have determined that you can use Supplement B, the process is relatively straightforward. First, you must ensure you are using the most current version of the form. Even if the original I-9 was completed on an older version, USCIS requires that any new entries in Supplement B be made on the version of the form currently in effect.
- Identify the Original Record: Confirm that the original Form I-9 belongs to the person you are rehiring.
- Enter the Full Name: At the top of Supplement B, enter the employee’s full name from the original Form I-9.
- Check for Name Changes: If the employee has legally changed their name since they last worked for you, record the new name in the appropriate fields.
- Record the Rehire Date: Enter the date the employee is returning to work in the “Date of Rehire” field.
- Review Work Authorization: If the employee is still authorized to work and their original documents have not expired (or are documents that do not require reverification, like a Green Card), you can proceed to the signature.
- Reverify if Necessary: If their authorization has expired, you must examine a new, unexpired List A or List C document. Record the document title, number, and expiration date in the supplement.
- Sign and Date: You must sign and date the supplement on the day the rehire or reverification takes place.
For more detailed technical instructions, we recommend reviewing Section 6.2 Reverifying or Updating Employment Authorization for Rehired Employees. Staying on top of I-9 form processing ensures that your files are always audit-ready.
Avoiding Penalties in the I-9 Process for Rehires
The cost of getting the i-9 process for rehires wrong can be surprisingly high. Common mistakes include using an outdated version of the form, failing to sign the supplement, or forgetting to reverify expired work authorization. These are not just administrative hiccups; they can lead to significant I-9 compliance penalties.
Another trap is “document discrimination.” This happens when an employer tells a rehired employee exactly which document they must bring for reverification. You must always allow the employee to choose which acceptable document to present from List A or List C.
The Three-Year Rule for Rehiring Employees
The “magic number” in rehires is three years. This timeframe is measured from the date of the initial execution of the previous Form I-9, not the date the employee left the company. If the employee returns within this 36-month window, you have the option to use Supplement B.
However, once that three-year mark passes, the old I-9 is effectively “retired” for rehire purposes. You must treat the individual as a brand-new hire. This means they must complete Section 1 no later than their first day of work, and you must complete Section 2 within three business days.
There are also instances where you might choose to complete a new Form I-9 even if you are within the three-year window. For example, if the original I-9 is messy, has multiple corrections, or was completed on a very old version of the form that makes it hard to read, starting fresh is often the safer bet. The Handbook for Employers M-274 clarifies that employers always have the option to treat a rehire as a new hire and complete a new form.
When you do use Supplement B, it is vital to keep it physically or digitally attached to the original Form I-9. This creates a clear “paper trail” that shows the employee’s history with your company. If you need a refresher on what documents are currently acceptable, our I-9 document requirements guide is a great resource to keep on hand.
E-Verify Requirements and Continuing Employment
If your business uses E-Verify, the i-9 process for rehires has an extra layer. The general rule is that if you complete a new Form I-9 for a rehire, you must also create a new E-Verify case. But what if you are using Supplement B?
If you rehire an employee within three years, use Supplement B, and you already have a previous E-Verify case on file that resulted in “Employment Authorized,” you typically do not need to create a new case. However, if you never ran them through E-Verify during their first stint with you, or if the previous case did not result in a clear “Employment Authorized” status, you must complete a new Form I-9 and create a new E-Verify case.
Special rules apply to seasonal workers or employees on leave. These situations are often considered “continuing employment” rather than a rehire. If an employee has a “reasonable expectation of employment at all times,” you may not need to do a new I-9 or Supplement B at all. Factors that suggest continuing employment include:
- The employee is on approved medical or family leave.
- The employee is part of a seasonal work cycle and returns every year.
- The employee was temporarily laid off due to a lack of work but was recalled.
For federal contractors, the stakes are even higher. The E-Verify Supplemental Guide for Federal Contractors outlines specific rules for verifying existing employees when a federal contract includes the FAR E-Verify clause. Ensuring E-Verify and I-9 compliance is essential for maintaining your eligibility for government contracts.
Best Practices for Record Retention and Compliance
Once the paperwork is done, the clock starts ticking on retention. You must keep an employee’s Form I-9 for as long as they work for you. Once they leave, you must keep the form for either three years after their hire date or one year after their termination date, whichever is longer.
When you rehire someone, the retention period essentially resets or extends based on the new dates. We recommend keeping all I-9s for rehires in a way that clearly links the original form with the new Supplement B. This avoids confusion during an audit where an officer might wonder why you have a rehire date but no original hire information.
To stay safe, we suggest the following best practices:
- Conduct Internal Audits: Regularly review your rehire files to ensure Supplement B is filled out correctly.
- Secure Destruction: Once the retention period has passed, securely destroy the forms to protect employee privacy.
- Use Digital Systems: Digital I-9 record keeping makes it much easier to track expiration dates and rehire windows than paper folders.
- Professional Help: If you are overwhelmed by a large number of seasonal rehires, using I-9 audit services can help identify and fix errors before the government finds them.
Frequently Asked Questions about Rehires
Can an employer specify which document a rehire must present?
No. Whether it is a new hire, a rehire, or a reverification, the employee always has the right to choose which documents to present from the Lists of Acceptable Documents. Telling a rehire they must bring their Social Security card or their Passport is a violation of anti-discrimination rules.
What should I do if the employee’s name has changed since they last worked here?
If you are using Supplement B for a rehire, there is a specific section to record a name change. You should record the new name to ensure your records match their current identity documents. While you are not strictly required to ask for proof of a name change, it is a best practice to be reasonably assured of their identity.
Is reverification required for U.S. citizens who are rehired?
No. U.S. citizens and noncitizen nationals never require reverification. If you rehire a U.S. citizen within three years and their original I-9 is on file, you only need to record the rehire date and sign Supplement B. You do not need to look at their Passport or ID again, even if the one on the original form has since expired.
