HR Checklist

Employee Onboarding Checklist

What to do, and when, from a signed offer to the ninety-day review.

36 steps
5 phases
7 with a legal deadline

Onboarding fails quietly. Nobody is fined for a laptop arriving late or a buddy who was never told — but those are what turn a good hire into an early leaver, and the paperwork that does carry a deadline gets buried among them.

This separates the two. Steps marked Deadline have a statutory clock, starting with Form I-9 on day one. Everything else is what makes somebody stay.

Before day one

Once the offer is accepted

Almost all of a good first day happens in the week before it. Equipment ordered, accounts provisioned, paperwork sent — so day one can be about people rather than forms.

Countersign the offer and file it with the agreed start date, title, pay and manager.
Complete background and reference checks, and record consent for each. Deadline
Send the new-hire paperwork ahead of day one, not on it. A first morning spent on forms is a first morning nobody remembers well.
Create the payroll record and confirm the first pay date and pay period. Including whether the first cheque is partial, which is the single most common first-week question.
Order equipment and confirm a delivery date before the start date. A remote hire whose laptop arrives on day three effectively starts on day three.
Provision accounts with the right role from the start: email, SSO, and only the tools the role needs. Copying another person’s permissions is how access creep begins on day one.
Assign a buddy or mentor, and tell them they have been assigned.
Write the first-day agenda and send it to the hire and the manager.
Tell the team who is joining, when, and what they will be working on.

First day

Day one

Two things at once: the forms that carry a federal deadline, and the introductions that decide how the next month feels. Form I-9 is the one with a clock that starts immediately.

Complete Form I-9, with Section 2 done within three business days of the start date. Deadline Federal, and the three-day clock runs from the first day of work for pay — not from the offer.
Collect Form W-4 and the state withholding equivalent. Deadline Without a W-4 you must withhold at the default single rate, which almost always surprises the employee.
Set up direct deposit and confirm the account details back to them.
Capture emergency contacts and any accommodation the employee wants recorded.
Offer the voluntary EEO self-identification, and make clear it is optional. Deadline
Walk through the handbook, code of conduct and acceptable-use policy, and record the acknowledgements.
Hand over equipment and log the serial numbers against the employee.
Confirm access works — before the end of the day, not on request.
Introduce the team in person or on a call, not by email.

Days 2–5

The first week

Reporting obligations first, then something real to finish. A new hire who has shipped nothing by Friday has learned that nothing is expected of them.

File the state new-hire report within the required window. Deadline Federal law requires reporting within 20 days of hire; several states are shorter.
Explain the benefits enrolment window and the date coverage actually begins. Deadline A missed enrolment window is a year-long consequence, so the deadline goes in writing.
Complete required security and data-handling training.
Complete harassment-prevention training where your state requires it. Deadline Several states mandate it on their own timetable for new hires; confirm the rule for the work state.
Book the recurring one-to-one, and hold the first one this week.
Give them something small and real to finish, and let them finish it.
Introduce the tools and where the answers live — runbooks, wikis, who to ask.

Days 6–30

The first month

Check the things that quietly go wrong — pay, benefits, access — and ask what onboarding missed while the answer is still specific rather than polite.

Agree written 30/60/90 expectations, with the manager, in one place.
Confirm benefits elections went through and coverage is active.
Check payroll landed correctly, including tax setup and any partial first period.
Hold a 30-day check-in that asks what is unclear, not whether they are happy.
Ask what onboarding missed while they still remember. This is the only window where the answer is specific rather than polite.
Review whether their access is right — usually it is now too broad, not too narrow.

Days 31–90

Settling in

Turn a new hire into a colleague, on the record. Reviews against what was actually written down in month one, and a probation outcome confirmed on time.

Hold the 60-day and 90-day reviews against the expectations written in month one.
Confirm any probationary period outcome in writing, on time.
Move them into the normal performance and goal cycle.
Close the onboarding record: paperwork complete, training logged, assets assigned.
Feed what went wrong back into this checklist. The cost of getting onboarding wrong shows up as an early exit, which is the most expensive kind.
