Right-to-work record retention in the United States
Reviewed by Mellow Editorial Team, HR & payroll content team
Employers must retain completed Form I-9s for each employee for either three years from the date of hire or one year after the date employment ends, whichever is later. That single rule governs right-to-work record retention for most US employers.
What "right to work" means here
In this context, "right to work" refers to employment eligibility verification — confirming that a person is legally authorized to work in the United States. This is separate from the labor-law concept of "right-to-work states" (which concerns union dues). The legal foundation is the Immigration Reform and Control Act of 1986, enforced today by US Immigration and Customs Enforcement (ICE) and the Department of Homeland Security. Every employer, regardless of size or industry, must verify employment eligibility using Form I-9.
The core retention rule
The formula is straightforward but easy to misapply:
- Three years from the date of hire, or
- One year from the date employment ends,
- whichever date is later.
Work through a quick example. You hire someone on March 1, 2024, and they leave on April 1, 2024. Three years from hire is March 1, 2027. One year from termination is April 1, 2025. March 1, 2027 is later, so that is your retention deadline. Now reverse it: you hire someone on March 1, 2020, and they leave on January 1, 2026. Three years from hire is March 1, 2023. One year from termination is January 1, 2027. January 1, 2027 is later — keep that I-9 until then.
The math matters because destroying records too early is itself a violation.
What to keep and how
You must retain the completed Form I-9 itself. You are not required to keep copies of the documents an employee presents (a passport, driver's license, Social Security card, and so on), but if you do make copies, you must retain them with the I-9 for the same period. Keeping copies inconsistently — for some employees but not others — can create discrimination exposure, so most employers either copy documents for everyone or no one.
Storage options. You may keep I-9s on paper, on microfilm or microfiche, or electronically. Electronic storage systems must meet specific standards set by DHS, including the ability to reproduce legible copies and maintain an audit trail of access and changes. Whatever format you choose, I-9s must be stored separately from the rest of an employee's personnel file. This matters during an inspection: an ICE audit targets I-9 records specifically, and mixing them into general HR files complicates production and can inadvertently expose unrelated personal data.
E-Verify. If you use E-Verify — mandatory for federal contractors and employers in certain states, voluntary for others — you still complete and retain Form I-9. E-Verify is a separate system that checks I-9 data against federal databases; it does not replace the form or alter the retention timeline.
Inspections and penalties
ICE can issue a Notice of Inspection giving you as little as three business days to produce your I-9 records. The Department of Justice's Immigrant and Employee Rights Section (IER) handles discrimination claims related to the verification process. Penalties for substantive paperwork violations — missing signatures, incomplete sections, wrong document lists — run on a per-form basis and are adjusted periodically for inflation. Knowingly hiring or continuing to employ unauthorized workers carries significantly higher penalties. The point is not to memorize penalty tiers but to understand that both under-documentation and over-documentation (asking for more or different documents than the form requires) carry legal risk.
Practical steps for staying compliant
Create a retention calendar. When you onboard someone, log their hire date and calculate the earliest date you could legally destroy their I-9. When they leave, recalculate. A simple spreadsheet works; so does an HR platform that tracks this automatically.
Audit your existing I-9s regularly. Self-audits — reviewing forms for completeness and correcting errors properly — are legitimate and advisable. Corrections must be made in a specific way: draw a line through the incorrect information, enter the correct information, and initial and date the change. Do not use correction fluid or otherwise obscure the original entry.
Train anyone who completes I-9s. Errors almost always come from the person filling out Section 2 (the employer section) rather than the employee. Common mistakes include accepting unacceptable documents, failing to complete List A or the List B/C combination, and missing re-verification deadlines for employees with temporary work authorization.
Plan for re-verification. If an employee's work authorization has an expiration date, you must re-verify before that date lapses. Re-verification happens in Section B of the current version of Form I-9. Permanent residents and US citizens are never re-verified. Missing a re-verification deadline puts the employer in the same legal position as failing to verify in the first place.
Keeping a clean I-9 process is largely a matter of consistent procedure rather than legal complexity — the rules are specific, but they do not change frequently, and the retention math, once understood, is repeatable.
