I-9 Verification and Payroll: What HR Needs to Know
Form I-9 Section 2 has to be completed within 3 business days of an employee's start date, with records kept 3 years after hire or 1 year after termination, whichever is later. BEG ties the new-hire report and payroll setup to that same clock and will hold a payroll start until Section 2 is confirmed done, at $45 per employee monthly.
The I-9 clock, day by day
- Day of hire: the employee completes Section 1 of Form I-9, no later than the first day of work for pay.
- Within 3 business days: the employer completes Section 2, examining the employee's original, unexpired documents in person.
- Exception, jobs under 3 days: if the position lasts fewer than three business days, Section 2 has to be done on the first day, not the usual three-day window.
- Ongoing: Supplement B covers reverification when a work authorization document expires, and rehires within three years of the original I-9.
Every employer that hires someone for pay in the U.S. after November 6, 1986 has to complete and retain this form. It has four parts: Section 1 for the employee, Section 2 for the employer, Supplement A for a preparer or translator who helped fill it out, and Supplement B for reverification and rehires.
Where the payroll record picks up
The practical connection between I-9 verification and payroll is the new-hire record itself. BEG files the state new-hire report and sets up the employee, W-4, and direct deposit inside the client's payroll system on the same start-date timeline Section 2 runs on, and can hold a payroll start until the client confirms Section 2 is complete. That is a scheduling safeguard, not a legal review: BEG does not examine the employee's documents or make the verification call.
Retention: a longer clock than most employers expect
Retention runs 3 years after the date of hire, or 1 year after employment ends, whichever is later, so a long-tenured employee's I-9 can stay on file for a decade or more. Forms can be kept on paper, microfilm, or electronically, but they have to be produced within 3 business days of a government inspection request, which is a tighter window than most other payroll records carry.
What a paperwork gap actually costs
Civil money penalties apply per violation for failing to properly complete, retain, or produce Forms I-9, with the amount set by DHS after weighing business size, good faith, seriousness, whether the worker was unauthorized, and prior history. A pattern or practice of knowingly hiring unauthorized workers can bring criminal exposure on top of the civil penalty. The good-faith paperwork defense, which softens penalties for honest clerical mistakes, is lost entirely if the violation is not corrected within 10 days of a DHS notice.
What employers get wrong
Asking for more documents than the list allows, or telling an employee which specific document to bring, feels like due diligence but is actually a prohibited practice. The employer has to accept any document from the acceptable list that reasonably appears genuine, and cannot pick and choose based on personal preference or assumptions about the employee.

Frequently Asked Questions
How many days does an employer have to complete Section 2 of Form I-9?
Three business days from the date employment begins, verified against original, unexpired documents the employee presents. An employee hired for fewer than three business days has to have Section 2 completed on the first day of work instead.
What are the four parts of Form I-9?
Section 1, completed by the employee. Section 2, completed by the employer. Supplement A, for a preparer or translator who assisted. Supplement B, used for reverification and rehires. Every employer hiring someone for pay in the U.S. after November 6, 1986 completes and retains the form.
How long does an I-9 have to be kept on file?
Three years after the date of hire, or one year after employment ends, whichever is later. Forms can be kept on paper, on microfilm, or electronically, and must be produced within 3 business days of a government inspection request.
Can an employer ask for a specific document, like a passport, for I-9 verification?
No. Asking for more or different documents than the list allows, or specifying which documents an employee must present, is a prohibited practice. The employer has to accept any acceptable document that reasonably appears genuine.
What penalties apply to I-9 paperwork violations?
Civil money penalties apply per violation for failing to properly complete, retain, or produce Forms I-9, with the amount set by DHS after weighing business size, good faith, seriousness, and prior history. A pattern of knowing hires of unauthorized workers can bring criminal penalties, and the good-faith paperwork defense is lost if a violation is not corrected within 10 days of a DHS notice.
Does BEG complete or sign Section 2 of the I-9?
No. Completing and signing Section 2, E-Verify, reverification, and any ICE audit response stay with the client and its immigration counsel. BEG does not verify work authorization.
How does I-9 verification connect to payroll setup?
The new-hire record is the connection point. BEG files the state new-hire report and sets up the employee, W-4, and direct deposit in the client’s payroll system, and can hold a payroll start until the client confirms Section 2 is complete.
What does BEG handle on new-hire onboarding?
BEG files the state new-hire report and sets up the employee, W-4, and direct deposit in the client's payroll system on the same timeline Section 2 runs on, all inside standard managed payroll at $45 per employee monthly.
What does BEG managed payroll cost?
$45 per employee per month, all-inclusive, inside the payroll software you already use, or on BEG's isolved HCM at the same rate.
