Onboarding checklist for small teams: who does what, by when

The first paycheck is where a missed onboarding step turns into a real problem. A W-4 that never came back, or bank details nobody chased, stays silent until payroll runs. On the first payday it shows up as tax withheld at the IRS default rate, or as pay that cannot land in the account the new hire expected.

An onboarding checklist, also called a new hire checklist, is the list of tasks between an accepted offer and day 30, each with one owner and one due date. This one is built for a US team of 10 to 50 people with no HR hire. I have seen onboarding from both sides: as a hiring manager writing the evaluation that decided the hire, and inside a large organisation’s graduate-intake programme, where onboarding ran to a written plan. This list keeps that discipline at small-team size, plus the legal deadlines that none of the six top-ranking checklists we read in October 2026 spelled out. Copy the table below, or take a printable first-week version of it by email at the end.

The onboarding checklist, with owners and due dates

The due dates count back from the start date: T-7 is seven days before day one, and T-5 is five. If the offer is accepted later than T-7, do items 1 to 5 straight away. Every line has one owner and one due date, because an item with no owner is the one most likely to slip.

#	Item	Due	Owner
1	Pass the interview notes and evaluation to whoever runs onboarding	Offer accepted	Hiring manager
2	Contract or offer letter signed	T-7	Founder
3	Hardware ordered and shipped to arrive before day one	T-7	Ops
4	New hire entered in payroll; Form W-4, state withholding form and payment details (direct deposit, or the method the new hire chooses) collected	T-5	Payroll owner
5	Health Insurance Marketplace notice given to the new hire	At hiring, with the offer paperwork	Payroll owner
6	Work email, chat and role-based tool access created	T-2	Ops
7	Hiring manager and buddy told the start date, with a link to this checklist	T-2	Ops
8	Day-one intro call and the 30-day check-in booked	T-1	Hiring manager
9	Form I-9 Section 1 completed by the new hire	First day of work, at the latest	Hiring manager
10	Accounts and permissions checked as working, without anyone using the new hire’s password	Day 1 morning	Ops
11	Intro with the hiring manager: what the role is for, what month one looks like	Day 1	Hiring manager
12	Form I-9 Section 2 completed (and E-Verify case, if you use it)	Within 3 business days of the first day of work	Hiring manager
13	First real task assigned: small, finishable, useful	Day 3	Hiring manager
14	Access gaps from the first days closed	Day 4	Ops
15	End-of-week check-in: what is unclear, what is missing	Day 5	Hiring manager
16	New hire reported to the state	Within 20 days of the first day of work; check your state for a shorter deadline	Payroll owner
17	This employee’s line checked in the first payroll	Before the first payroll is submitted	Payroll owner
18	30-day check-in held	Day 30	Hiring manager
19	Checklist corrected with what this hire turned up	Day 30	Onboarding owner

I have not seen a company run item 1 on purpose: the interview scorecards stay in the applicant tracking system and onboarding starts from a blank page. The reasons for that, and the full 1–7–30–90 rhythm this checklist feeds, are in our plan for onboarding a new employee. This page is the list; that page is the method.

The First-Paycheck Line: what must be done before payday

The First-Paycheck Line separates the items your first payroll run depends on from everything else. Item 4 holds them: the employee in payroll, Form W-4, the state withholding form and the payment details. If item 4 slips past its due date, the first paycheck is at risk, and item 17 is the last chance to catch it.

I mark the list this way because the two sides fail differently. A login that does not work on day one is annoying, and it gets fixed by lunch. A W-4 that never came back is silent until payroll runs, and then the IRS rule applies: if an employee does not give you a valid Form W-4, you withhold as if they were “single or married filing separately with no other entries on step 2, 3, or 4” (IRS Topic 753).

That default may not match their situation, and they find out on their first payslip.

So item 4 gets a due date of T-5, not “first week”, and the payroll owner checks this employee’s line before the first payroll is submitted (item 17), while there is still time to correct it. If your payroll tool lets the new hire enter their own W-4 and bank details (worth checking when you choose payroll software), that saves typing, not checking: someone still confirms it was done.

The US paperwork deadlines, in one table

Four federal requirements apply to a new employee at a small US business: Form I-9, Form W-4, the new hire report and, for employers covered by the Fair Labor Standards Act, the Health Insurance Marketplace notice. E-Verify adds a deadline where you use it, and workplace posters are a standing duty rather than a per-hire form.

Paperwork	Rule	Who keeps it, or where it goes	Source
Form I-9, Section 1	Employee completes it no later than the first day of employment	Employer, on file	USCIS
Form I-9, Section 2	Employer examines the documents within three business days of the first day of employment (no later than the first day if the job lasts under three business days)	Employer, 3 years after hire or 1 year after employment ends, whichever is later	USCIS
E-Verify (where used)	Case created no later than the third business day after the employee starts work for pay	Case held in E-Verify	E-Verify
Form W-4	Ask every new employee to complete one; without a valid form, you withhold at the IRS default (single or married filing separately)	Employer, at least 4 years	IRS
State new hire report	Name, address, SSN, date of hire, employer name, address and FEIN, reported within 20 days of the date of hire, the first day the employee works for pay (some states sooner, some want more data)	Sent to your State Directory of New Hires	ACF
Health Insurance Marketplace notice	Employers covered by the Fair Labor Standards Act give it to each new employee at the time of hiring, full-time or part-time	The employee keeps it	DOL
Workplace posters	Covered employers post the federal notices that apply to them, such as the EEOC “Know Your Rights” poster	On display	EEOC

This table is operational guidance, not legal advice: confirm anything unusual with your state’s new hire office or an employment lawyer.

Three points the table cannot hold. The current Form I-9 edition is dated 01/20/25, and USCIS says not to file it with USCIS or ICE: you keep it (USCIS Form I-9). E-Verify is required for covered federal contractors (E-Verify) and by some states, so check your own state before you decide you do not need it. And a properly classified independent contractor is not an employee: they give you a Form W-9, not a W-4 (IRS), and the federal new hire report covers employees; whether your state also wants contractors reported is a state rule, so check it.

The withholding form depends on your state rather than on federal law, and some states add their own new hire paperwork. If the new hire works in a different state from your office, the report normally goes to the state where they work; an employer with staff in several states can instead register as a multistate employer and report every new hire to one of those states (ACF). Check the right state’s withholding form and deadlines before item 4.

How to use this checklist in a team with no HR

The owner column uses five roles: founder, payroll owner, hiring manager, ops and onboarding owner. In a 10 to 50-person company, two or three people often hold all five, and that works as long as each line carries a real name. Filter the table by owner and send each person their rows, not the whole document.

The onboarding owner is the person who holds the list itself, and they are not there to do the other rows’ work. On day 5 and day 30 they check that every line due by then has a tick, and after each hire they run item 19.

Item 19 is how the checklist improves. A new hire often turns up a gap the list did not cover, and the fix goes in before the next one starts.

A shared spreadsheet is enough for the first few hires. Once you hire more than once a quarter, the payroll set-up in item 4 is worth handing to your payroll tool’s self-service onboarding, and the account steps (item 6) to an automation layer. Where onboarding sits among the other HR jobs worth systematising is mapped in our guide to HR automation across the employee lifecycle. When you would rather buy the checklist engine than keep a spreadsheet, the onboarding software picks for small teams compare the priced options.

What this checklist costs you to run

Run by hand, this checklist costs time rather than money: a shared spreadsheet is enough to hold it. The real cost is the hours of the people who own each row, and the price of a missed deadline, which is why the deadlines sit in the table rather than in anyone’s memory.

To put a number on those hours, our breakdown of what it costs to onboard a new employee prices one hire line by line with the First-90-Days Ledger. The useful habit is to time your next hire once, by hand, and keep that number: it tells you whether software would save you anything at your hiring volume.
