How Long Should Employers Keep I-9 Forms After Termination?

The short answer: use the later of two dates

Employers must retain an employee’s Form I-9 for three years after the date of hire or one year after employment ends, whichever is later. Employers must also keep the form throughout the person’s employment, even when that employment lasts longer than three years.

That means “keep every I-9 for three years” is not a complete retention policy. Neither is “delete the I-9 one year after termination.” Either shortcut can cause an employer to destroy a required record too soon.

For employers hiring at volume, the practical challenge is connecting each I-9 to accurate employment dates—and making sure a calculated deadline does not trigger destruction without appropriate review.

How to calculate the I-9 retention deadline

For a terminated employee, calculate both dates:

1. Date of hire plus three years. For this purpose, use the employee’s first day of employment for pay, not the offer date or the date someone uploaded the form.
2. Employment end date plus one year. Use the actual termination date reflected in your employment records.
3. Select the later date. Keep the I-9 through the applicable retention period.

For an active employee, do not schedule destruction just because the three-year anniversary has passed. The form remains required while that person works for you.

Two examples that show why both dates matter

The long-tenured employee’s deadline is driven by termination. The short-tenured employee’s deadline is driven by the original hire date.

This distinction matters for seasonal operations, hospitality groups, staffing businesses, and other employers with frequent early turnover. A short employment period does not necessarily mean a short post-termination retention period.

What belongs with the retained I-9?

Retention is about preserving the complete record, not simply keeping the first page of a form.

As applicable, maintain:

• The completed Form I-9.
• Associated supplements, including completed preparer or translator certifications and reverification or rehire records.
• Corrections and attached explanations that belong with the form.
• Copies of identity or employment authorization documents retained as part of the I-9 process.

Document-copying requirements vary. For example, E-Verify and the DHS alternative procedure for remote document examination can impose particular copying requirements. Confirm the requirements that apply to your process rather than assuming that copying documents is always optional—or always required.

A document copy does not replace a completed I-9. Likewise, a completed I-9 does not eliminate any applicable obligation to retain required copies.

Employers reviewing their broader onboarding controls can use this practical Form I-9 compliance checklist alongside a dedicated retention procedure.

Where should employers store I-9 records?

Employers may retain I-9 records in permitted paper or electronic formats. The important questions are whether the records remain complete, legible, secure, and accessible for inspection.

Separate storage is a useful control

Keeping I-9s separate from general personnel files is a practical records-management approach, not a blanket federal requirement to use a particular filing system.

Separate storage can make it easier to:

• Limit access to sensitive identity information.
• Retrieve records for an inspection without exposing unrelated personnel materials.
• Apply the I-9 retention schedule independently of payroll or benefits schedules.
• Review terminated-employee records for eligible destruction.

A centralized system can support these goals, but a system label alone does not establish compliance.

Electronic storage needs more than an upload folder

Electronic I-9 systems must meet applicable regulatory requirements, including controls addressing integrity, accuracy, reliability, access, and the ability to reproduce records. Applicable indexing, quality assurance, and audit-trail requirements also matter.

Before replacing paper records with electronic copies, verify that the digitization and storage process satisfies the requirements and that every retained page is readable. Do not assume an ordinary shared drive meets every electronic I-9 requirement.

For official guidance, consult USCIS I-9 Central and the current Handbook for Employers. Confirm current requirements before changing storage methods or adopting an automated deletion workflow.

Build a retention workflow that survives turnover

A written rule is helpful. A repeatable workflow is better, especially when HR, payroll, and local managers maintain different parts of the employee record.

1. Assign a reliable source for employment dates

Identify which system owns the first day of employment and termination date. Resolve discrepancies before calculating a destruction deadline.

A payroll processing date, final paycheck date, or account deactivation date should not automatically substitute for the actual employment end date.

2. Calculate deadlines when employment ends

Add the terminated employee to a retention register. Useful fields include:

• Employee name and unique identifier.
• Hire date and termination date.
• Both calculated retention dates.
• Controlling retention deadline.
• Record location.
• Hold status and review owner.

Avoid placing Social Security numbers or document images in the register when identifiers and record references will do.

3. Review exceptions before destruction

Do not let a date formula make the final decision by itself. Check for rehires, corrected employment dates, inspections, litigation holds, and other preservation obligations.

Rehires deserve particular attention because the applicable I-9 process and the employee’s current status can affect what must remain on file. An active employee’s record should not be deleted because an earlier termination created an old destruction task.

4. Document approved disposal

After the retention period has expired and applicable holds have been cleared, dispose of eligible records securely. Paper should be securely destroyed; electronic disposal should account for system copies, exports, and backup practices under your records policy.

Keep a disposal log showing the record reference, approval, and destruction date without reproducing the sensitive information you intended to remove.

Avoid these common retention mistakes

Deleting all records one year after termination. This overlooks the three-year-from-hire requirement for short-tenured employees.

Deleting active employees’ forms after three years. Their forms must remain on file throughout employment.

Treating every HR record as subject to the same schedule. I-9s, payroll records, tax documents, and personnel records can have different requirements.

Keeping everything indefinitely by default. Unnecessary retention increases the volume of sensitive information you must protect. Use an approved schedule rather than treating permanent storage as the only safe option.

Assuming a vendor handles every exception. Confirm who calculates deadlines, checks holds, approves destruction, and retrieves records. Trak’s Form I-9 verification and E-Verify services can be part of a more consistent compliance workflow, but responsibilities should always be explicit.

Make retention part of offboarding

The best time to establish the retention deadline is when employment ends—not when someone discovers a crowded filing cabinet or an aging digital archive.

Use accurate dates, calculate both deadlines, preserve the complete record, and review exceptions before disposal. This article provides practical information, not legal advice; consult qualified counsel about unusual employment histories or preservation obligations.
