Two deadlines, and almost everyone remembers them slightly wrong. Section 1 is due by the end of the employee’s first day of work. Section 2 is due within three business days of the first day of work. Neither one is counted from the offer, the start date on the contract, or the day the paperwork got emailed over.
How to count the three days
The clock runs on business days, and the first day of work is day zero. Start work Monday, and Section 2 is due by end of day Thursday. Start Thursday, and with a normal weekend you have until Tuesday.
Federal holidays do not count as business days, which quietly buys you a day around Thanksgiving and Memorial Day. It also means a Wednesday start before a Thursday holiday is tighter than it looks if your representative is unavailable Friday.
The exception for very short assignments
If someone is hired for fewer than three business days, Section 2 must be completed by the end of the first day of employment. There is no three-day grace period for a one-day or two-day job. This catches employers using day labor, event staff, and short-term contractors treated as employees.
Section 1 is the employee’s job, not yours
The employee completes Section 1 no later than the end of their first day. They may complete it earlier, after accepting the offer, but not before an offer has been accepted.
You cannot fill it in for them, and you cannot correct it for them later. If there is an error in Section 1, the employee is the one who lines it through, writes the correction, and initials and dates it. A preparer or translator can help, and if they do, the preparer and translator certification block has to be completed.
Two Section 1 fields that used to be forgiving are now not: a missing date of birth and a missing date beside the employee signature both became substantive violations in March 2026, fineable immediately with no cure period.
We act as your authorized representative and complete Section 2 in person anywhere in the five boroughs, which works for any employer. If your company is enrolled in E-Verify, we can also complete it by live video nationwide. Same-day signed PDF, from $65 per employee.
What happens if you miss it
You do not get to skip the form. A late I-9 is still required, and you complete it as soon as you realize.
Do not backdate it. Ever. Enter the actual first day of employment in the certification, attach a signed and dated explanation of the corrective action, and keep it with the form. Backdating turns a paperwork problem into a much worse one.
What you cannot do is withhold pay or a W-2 to force compliance. You may not hold back wages for work already performed for any reason connected to Form I-9.
Why the deadline is where the money is
The three-day rule is the reason same-day verification is worth paying for. A remote hire in another borough starting Monday means the document examination has to happen by Thursday. If your representative cannot get there, you are choosing between a late form and delaying someone’s start.
Since March 2026, a missing first day of employment in the certification is itself a substantive violation. The date matters as much as the deadline.
How to stay ahead of it
Send Section 1 with the offer acceptance, not on the first morning. Book the Section 2 appointment when you set the start date, not after the employee arrives. Confirm before day one which documents the employee plans to bring, without telling them which to choose. And if you are not enrolled in E-Verify, remember that the review has to happen in person, which means someone has to physically be there inside three business days.
Frequently asked questions
Is it three calendar days or business days?
Business days, and the first day of work does not count as one of the three.
Can Section 1 be completed before the start date?
Yes, after the employee accepts the job offer. Not before.
What if the employee starts on a Friday?
The weekend does not count. Section 2 would be due by the end of Wednesday.
Can I let someone work while we wait on the paperwork?
The form is the compliance obligation and its deadline is fixed. Complete it inside the window rather than treating it as catch-up work.
Do you offer rush verification?
Yes. Same-hour verification is $95 when a hire needs to start immediately.
Counting the three days correctly
The first day of work is day zero. If somebody starts on Monday, Section 2 is due by the end of Thursday. Start on Thursday and, with an ordinary weekend, you have until Tuesday.
Federal holidays are not business days, which quietly adds a day around Thanksgiving and Memorial Day. It also means a Wednesday start before a Thursday holiday is tighter than it looks if your representative is unavailable on the Friday.
Count it when the start date is agreed, not on the morning of day three.
Remote hires make the deadline harder, not softer
The three days do not stretch because the employee lives elsewhere. If you are not enrolled in E-Verify, somebody has to physically examine the original documents within the window, which means arranging a person in their city.
That is the practical reason employers use an authorized representative. It is also why the arrangement should be made when the offer is accepted rather than after the start date. See E-Verify vs Form I-9.
Late forms, and what not to do
If the deadline passed, complete the form as soon as you realize. Do not backdate anything. Enter the actual first day of employment in the certification and attach a signed, dated explanation of the corrective action taken.
Backdating converts a paperwork violation into something far worse, and it is the kind of thing that surfaces because two documents in the same file disagree with each other.
Since March 2026 a missing first day of employment in the certification is itself a substantive violation, fineable immediately with no correction window. See what changed.
Section 1 belongs to the employee
The employee completes Section 1, and an employer may not fill it in for them. If there is an error, the employee makes the correction, initials and dates it.
A preparer or translator may help, and where they do, the preparer and translator certification block must be completed. If a different preparer helped originally, their details are lined through and the new details entered, noted as being for corrections.
Two Section 1 fields deserve attention because they moved category in March 2026: a missing date of birth and a missing date beside the employee signature are now substantive violations, fineable immediately with no ten day cure.
Building the deadline into hiring
The employers who never miss this treat it as part of onboarding rather than paperwork that follows it.
Send Section 1 with the offer acceptance so it is done before day one. Book the Section 2 appointment when the start date is agreed, not after the person arrives. Confirm in advance that the employee has unexpired identification, without telling them which documents to bring. And know before the offer whether your company is enrolled in E-Verify, because that decides whether a remote hire can be verified by video or needs somebody physically present.
