The retention rule fits in one sentence. The trouble starts when a notice of inspection arrives and the forms are in a basement, mixed into personnel folders or filed under a system only one retired HR manager understood. Three business days is not long to find, check and hand over paper for everyone you have employed in the past several years.

This guide covers the I-9 retention requirements in federal rules, how to calculate the date for each former employee, what belongs in the retained file, where the forms can live and how to plan a retrieval before you need one. It is general information for HR teams, not legal advice, so involve your employment or immigration counsel on anything specific.

How Long Do You Have to Keep a Form I-9

The rule sits in 8 CFR 274a.2(b)(2), and the U.S. Citizenship and Immigration Services (USCIS) restates it in its Handbook for Employers (M-274): three years after the date of hire, or one year after the date employment ends, whichever is later. Nothing in that wording depends on how the form is stored, so a paper form in a box and a form in an electronic system run on the same clock.

Form I-9 is one record among many in an employee file, and each has its own clock. Our employee records retention schedule lists the others, including payroll, benefits and safety records, and states can add their own rules on top of federal minimums, as our records retention guidelines by state show. If you are unsure which records govern a given file, keep the I-9 question separate. It has its own rule and its own inspection process.

How to Calculate an I-9 Retention Date

There is no form to file and no agency to ask. You run the same two-date calculation for each person who leaves. Hire here means the day the person actually began work for pay, the date in the First Day of Employment field, not the offer date. One exception: if you rehired someone on their existing form, the three years run from the date that form was first completed. The examples below use invented dates to show how the rule plays out.

Employee	First day	Last day	First day plus 3 years	Last day plus 1 year	Keep until
A, left after a few months	Mar 3, 2022	Jun 10, 2022	Mar 3, 2025	Jun 10, 2023	Mar 3, 2025
B, long service	Jan 9, 2018	Sep 30, 2025	Jan 9, 2021	Sep 30, 2026	Sep 30, 2026
C, left after 18 months	Aug 1, 2024	Feb 14, 2026	Aug 1, 2027	Feb 14, 2027	Aug 1, 2027
D, exactly two years	Nov 12, 2023	Nov 12, 2025	Nov 12, 2026	Nov 12, 2026	Nov 12, 2026
E, still employed	Apr 2, 2015	None	Does not apply	Does not apply	Keep while employed

Notice employee A. Someone who left after a few months still has a form that must be kept for three years from the start date, which is a common source of mistakes. Teams that apply a flat “one year after termination” rule will lose forms they were required to keep, and teams that apply a flat “three years from hire” rule will lose the forms of long-service employees like B, whose three years ran out while they still worked there.

If a colleague asked how to handle this without a spreadsheet full of formulas, the honest answer is to do it once, at offboarding. Calculate the keep-until date on the day the person leaves, write it on the folder or into your index, and move the form out of the active set. An I-9 retention calculator is only useful if someone runs it at the moment the last day is known. Nobody wants to rebuild 400 dates from old payroll data the week an inspector calls.

What Goes in the Retained File

USCIS says employers need only retain the pages that the employer and the employee wrote on, and that any copies or electronic images of an employee’s documents are kept for the same period. Under the regulation, those copies stay either with the form or in the employee’s records, and USCIS says they must be available at inspection, so filing them with the form is the simpler choice. In practice that means the file for one person may hold more than one sheet, so a retrieval plan that assumes one page per employee can leave things behind.

USCIS also recommends keeping Forms I-9 separate from personnel records so inspections are easier. There is a privacy reason too: an inspector looking at I-9s has no need to see performance reviews or medical leave paperwork. One practical setup is two sets, active employees and former employees, with former employees sorted by keep-until date so the file shows at a glance what is still in scope.

Where to Store I-9 Forms: On Site, Off Site, Paper or Electronic

The M-274 handbook says paper forms may be kept on site or at an off-site storage facility, as long as you can present them in the required time. The regulation adds a practical detail. Forms must be made available at the location where the request for production was made, and if they are kept somewhere else, you must tell the officer where they are and arrange the inspection. Off-site storage is allowed, then, but it does not pause the clock.

• Paper. Forms with original handwritten signatures. Paper needs nothing more than a dry, secure, indexed home, but a shelf in a storeroom gets you only part of the way. Someone still has to find the right forms quickly.
• Microfilm or microfiche. Allowed if the film preserves the image for the full retention period, with well-maintained viewing equipment and an index.
• Electronic. Allowed, and the rules are detailed. 8 CFR 274a.2(e) through (g) call for controls on integrity and accuracy, an index, quality checks, restricted access, backup and recovery, and a record of who created or changed each form. Forms signed electronically must also meet the signature standards in paragraphs (h) and (i). The same retention period applies, and the same three business days.

Whichever you use, the same weak point shows up: indexing. A box labeled “HR 2019” tells you nothing about who is inside it. For I-9s, an index that works at folder level records the employee name, first day, last day, keep-until date and work location. With those five fields, you can answer an inspector’s request for a date range or a site without opening every box.

What Happens in an I-9 Inspection

Immigration and Customs Enforcement (ICE) describes the process in its Form I-9 inspection fact sheet: a Notice of Inspection, at least three business days to produce the forms, then a review. Employers get at least ten business days to fix technical or procedural failures, and any left uncorrected become substantive violations. Substantive violations have no such correction period, and failing to present a form on request is one of them. The law firm Alston & Bird reported that ICE revised that fact sheet in March and August 2026, and that the March version moved 17 common errors from correctable failures to substantive violations, so check the current version rather than an old summary.

ICE is not the only agency that can ask. USCIS lists officers of the Department of Homeland Security, the Immigrant and Employee Rights Section of the Department of Justice and the Department of Labor. Under the regulation, no subpoena or warrant is needed for an inspection, and refusing or delaying presentation of the forms counts as a violation of the retention requirement.

The current paperwork penalty, in 8 CFR 274a.10(b)(2), runs from $288 to $2,861 per individual for violations after November 2, 2015. The amount depends on factors such as company size, good faith and the seriousness of the violation. Multiply even the low end by a few hundred former employees and a missing box stops being a filing problem.

A Three-Day Retrieval Plan for Stored I-9s

Most retrieval problems are ownership problems. The notice lands with a receptionist or a site manager, a day passes, and only then does anyone ask where the forms are. A one-page plan closes that gap. The timeline below is our suggestion, and it should be adapted with your counsel.

When	What to do	Who usually owns it
Day the notice arrives	Record the date and the deadline. Call counsel. Confirm which people, sites and dates are requested. Stop any planned disposal of I-9s and related records, such as payroll and employee lists.	HR lead, counsel
Same day	Pull an employee list for the period from payroll. Use the index to find the boxes or folders that hold those forms, and request them.	HR records owner
Business day 1	Receive the forms. Check the list against what arrived and note any gaps. Request anything missing. Do not create, complete, change or backdate any form. Take gaps to counsel.	HR records owner
Business day 2	Review with counsel. Separate the I-9s, and any document copies kept with them, from anything that was not requested. Copy what you plan to keep as your own record of the production.	Counsel, HR lead
Business day 3	Produce the forms as counsel directs, and log what went out, to whom and when.	Counsel

Test the plan once a year. Pick a site and a date range, time how long it takes to get the forms in hand, and fix whatever slowed you down. A practice run costs an afternoon, and it tells you whether your index is as good as you think.

What Happens When a Form Reaches Its Date

Reaching the date does not make anything happen automatically, and it should not. A form tied to a pending charge, lawsuit or foreseeable dispute needs to stay where it is, as our employee records schedule explains. Whether a form that clears review stays in storage or goes through documented disposal is a decision for HR and counsel, made under your own retention policy. Our business records retention guide covers how to build that policy.

How GRM Stores I-9 Forms and Employee Records

With offsite document storage from GRM, records are barcoded, entered into an inventory system and shelved in controlled facilities. Each movement is logged, which gives you a barcode-based chain of custody for every box or file. Deliveries and pickups are carried out by GRM employees.

Through the eAccess portal, HR teams can search by barcode, keyword or metadata and request deliveries, pickups and scanning, and users can be added or removed by department or job function. If your files are indexed at folder level and you know which employees a notice covers, that search is where your retrieval plan starts. How eAccess supports faster physical records retrieval goes into more detail. GRM can also manage individualized retention policies, which keeps keep-until dates from depending on one person’s memory.

Paper is often only part of the file. An HRIS does a good job with employee data but is not built to manage the documents themselves, and an inspection asks for documents. For I-9s and employee documents kept electronically, GRM works with its sister company, VisualVault, whose HR Governance Manager adds a document layer alongside the HRIS: one profile per employee, documents classified and filed automatically, role-based permissions, retention policies and a full audit trail. Its optional HR Audit Manager module prompts HR to check that each employee profile holds the required documents, which is the kind of gap an I-9 inspection exposes.

Frequently Asked Questions

How long do employers have to keep Form I-9?

Employers must keep Form I-9 for as long as the person is employed. After employment ends, the form must be kept until three years after the date of hire or one year after the date employment ends, whichever is later. The same period applies to paper, microform and electronic forms.

How do you calculate an I-9 retention date?

Add three years to the date of hire, add one year to the last day of employment, and use the later of the two dates. As a shortcut, for someone who worked less than two years, count three years from the first day of employment. For someone who worked more than two years, count one year from the last day.

Can I-9 forms be stored off site?

Yes. USCIS allows paper Forms I-9 to be kept on site or at an off-site storage facility, as long as the employer can present them within three business days of an inspection request. If the forms are kept at another location, the employer must tell the officer where they are and arrange the inspection.

Should I-9 forms be kept in personnel files?

USCIS recommends keeping Forms I-9 separate from personnel records, because that makes inspections easier. Separate storage also keeps unrelated employee information, such as performance reviews or leave paperwork, out of an inspection. One practical approach is to keep one set for current employees and another for former employees, sorted by the date each form can be reviewed.

What happens if you cannot produce I-9 forms during an inspection?

Refusing or delaying presentation of Forms I-9 is a violation of the retention requirement, and an officer may issue a subpoena if a request is not met. Paperwork penalties currently run from $288 to $2,861 per individual, depending on factors such as company size, good faith and seriousness. Contact counsel as soon as a notice arrives.
