A start date is the first day a new employee actually works. It is more than a calendar entry, because it starts the clocks for Form I-9, new hire reporting, benefit waiting periods and leave eligibility.
| Item | Rule | Source |
|---|---|---|
| Form I-9 Section 1 | By the first day of work | 8 CFR 274a.2 |
| Form I-9 Section 2 | Within 3 business days of the first day | 8 CFR 274a.2 |
| New hire report | Within 20 days, sooner in some states | 42 USC 653a |
| FMLA service | 12 months of service needed | 29 USC 2611 |
| Benefits, PTO, probation | As set in the plan or policy | Company policy and plan documents |
The first day of work entry covers what to plan for the day itself, and Form I-9 covers the documents.
A clinic hires a medical assistant whose start date is Thursday, January 7, 2027. She completes Section 1 of Form I-9 on the morning of the 7th, before her first shift.
Section 2 is due within three business days of the first day. Counting Friday the 8th, Monday the 11th and Tuesday the 12th, the clinic must examine her documents and complete Section 2 by Tuesday, January 12.
The new hire report is due within 20 days, by January 27, unless the state has a shorter deadline. The clinic’s health plan starts coverage on the first of the month after 30 days, so her coverage begins on March 1. Her one-year anniversary for FMLA service is January 7, 2028. HR puts all four dates in her file the day she starts.
Start dates move, for a background check that takes longer, a notice period at the candidate’s old job, or a delay at the site. Confirm any change in writing, with the new date and anything else that changes, such as the first shift or the location.
Be careful with early paperwork and visits. Asking a new hire to come in before the start date to complete forms is fine if it is short and voluntary, but training, shadowing or any work makes that day the real start date, and the time must be paid. Form I-9 Section 1 can be completed after the offer is accepted and before the first day.
A logistics company offers a forklift operator a start date of Monday, March 1. The background check is delayed, so it moves the date to March 8 by email, then to March 15 by phone.
When the operator arrives on March 15, he says he understood March 8 and lost a week of work at his old job waiting. The company now confirms every start date change in writing through the onboarding forms, so both sides have the same date and nobody relies on a phone call.
The first day an employee actually works for the company.
Often, but not always. Some employers record the hire date as the day the offer was accepted. For I-9 timing, the first day of work is what counts.
Yes, an employer can move a start date, and it should confirm the new date in writing. Any hours already worked must be paid.
Section 1 by the first day of work, and Section 2 within three business days of the first day.
Yes. The first day of paid work, including training or orientation, is the real start date for the I-9 and other deadlines.
Yes. Section 1 of Form I-9 can be completed after the offer is accepted, and other forms can be sent ahead. Any required work or training must be paid.
Send digital HR forms for e-signature before day one, and keep every signed document in the employee’s digital file.
