Form I-9 Compliance for Small Employers: Deadlines, Documents and Common Mistakes

Every U.S. employer, whatever its size, must complete a Form I-9, Employment Eligibility Verification, for each person it hires to work in the United States. It is one of the first compliance tasks a new business faces, and one of the most common places small employers make mistakes, usually because the form gets handed to whoever is doing onboarding that week.

This guide covers the essentials: deadlines, what the employee and employer each do, acceptable documents, remote verification, storage and retention, reverification, and how to fix errors. U.S. Citizenship and Immigration Services (USCIS) publishes the form, its instructions and the M-274 Handbook for Employers at uscis.gov/i-9; when in doubt, those are the authoritative sources. This article is general guidance, not legal advice.

Who needs a Form I-9

You need a completed I-9 for every employee hired after November 6, 1986, including part-time, seasonal and remote employees, and including family members on payroll. You do not complete an I-9 for genuine independent contractors, though misclassifying an employee as a contractor creates its own problems with the IRS and the Department of Labor.

The two deadlines

• Section 1 (employee): completed and signed by the employee no later than their first day of work for pay. They can complete it after accepting the offer, but not before.
• Section 2 (employer): completed within three business days of the employee's first day of work. If the job will last fewer than three business days, Section 2 is due by the end of the first day.

Missing the Section 2 deadline is one of the most common paperwork violations. Build the I-9 into your first-day checklist rather than leaving it to "sometime this week." Our new hire onboarding playbook shows where it fits.

Section 1: what the employee does

The employee enters their information, attests to their citizenship or immigration status, and signs. If someone helps them fill it out, such as a translator, the helper completes the preparer/translator area. The employer should review Section 1 for completeness but must not tell the employee which status box to check.

Section 2: what the employer does

Within the deadline, the employer (or an authorized representative) must physically examine, or remotely examine if eligible (see below), the employee's original, unexpired documents and record them in Section 2.

The employee chooses which documents to present from the Lists of Acceptable Documents on the form:

• One document from List A, which shows both identity and work authorization (for example, a U.S. passport or a permanent resident card), or
• One document from List B (identity, such as a driver's license) and one from List C (work authorization, such as an unrestricted Social Security card or a birth certificate).

Two points trip employers up:

• You cannot ask for specific documents. Requesting a particular document, asking for more than the form requires, or rejecting reasonable-looking documents can be unlawful discrimination under the Immigration and Nationality Act's anti-discrimination provision. The Department of Justice's Immigrant and Employee Rights Section (IER) enforces it and publishes employer guidance.
• Examine, then decide. If a document reasonably appears to be genuine and to relate to the person presenting it, accept it. You are not expected to be a document expert.

Remote document examination

Since August 1, 2023, employers enrolled in E-Verify and in good standing may use a Department of Homeland Security alternative procedure to examine documents remotely: review copies of the documents, conduct a live video interaction where the employee presents them, keep copies, and check the alternative-procedure box on the form. Employers not enrolled in E-Verify must still examine documents physically, though they may use an authorized representative near the employee, such as a notary or another trusted person, to complete Section 2 on their behalf. The employer remains responsible for that representative's mistakes.

E-Verify

E-Verify is the federal online system that compares I-9 information with government records. It is voluntary for most private employers under federal law, but some states require it for certain employers, often public contractors, and federal contracts can require it too. If you enroll, you must use it consistently for all new hires at the enrolled locations, and only after the I-9 is completed.

Storing and retaining I-9s

• Keep I-9s separate from personnel files. Store them together in one secure place, paper or electronic, so you can produce them quickly if asked and so that information about citizenship and national origin isn't sitting in files managers can see.
• Copies of documents are optional, except under the remote alternative procedure. If you do make copies, do it for every employee, not selectively.
• Retention: keep each form for three years after the date of hire or one year after employment ends, whichever is later. Keep it for current employees for as long as they work for you.
• Inspections: if Immigration and Customs Enforcement (ICE) serves a Notice of Inspection, employers generally have three business days to produce the forms.
• Electronic systems are allowed if they meet the government's standards for integrity, security and audit trails.

Reverification and rehires

Some employees have work authorization with an expiration date. Before it expires, the employer must reverify using the supplemental form for reverification. Do not reverify U.S. citizens, and do not reverify an expiring permanent resident card or List B identity documents. For rehires within three years of the original I-9 date, you may be able to use the reverification and rehire supplement rather than a new form.

Fixing mistakes

Nobody gets every form right. If you find an error:

• Correct it by drawing a line through the wrong information, writing the correct information, and initialing and dating the change. Employees must correct their own Section 1 errors.
• If a form is missing, complete one now with the current date. Never backdate.
• Don't white out, erase or recreate a form to hide an error. Attach a short, dated note explaining a correction if it helps.

ICE and IER have published joint guidance for employers conducting internal I-9 audits. A good audit applies the same review to every employee, not only those who seem "foreign," which would raise discrimination concerns.

A short I-9 checklist

1. Use the current edition of the form from uscis.gov/i-9.
2. Section 1 on or before day one; Section 2 within three business days.
3. Let the employee choose documents from the lists; never specify.
4. Examine originals in person, or use the remote procedure only if enrolled in E-Verify.
5. Store forms separately and securely; copy documents for everyone or no one.
6. Track expiration dates for reverification.
7. Purge forms only after the retention period, on a schedule.
8. Audit once a year, consistently.
