New Hire Paperwork
Definition
New hire paperwork is the set of forms and documents an employer collects when someone joins, covering legal requirements such as Form I-9 and Form W-4, state tax and new hire reporting, payroll and benefits enrollment, and company documents such as policy acknowledgments. Most of it can and should be completed before day one.
Also called: New employee forms, Onboarding documents, New hire packet, Onboarding paperwork
Federally required forms (US)
Every US employer needs these for every employee, regardless of size or state:
- [Form I-9](/glossary/form-i-9/), Employment Eligibility Verification. Confirms identity and authorization to work in the US. The employee completes Section 1 by the first day of work, and the employer completes Section 2 within three business days of the start date.
- [Form W-4](/glossary/form-w-4/), Employee's Withholding Certificate. Tells payroll how much federal income tax to withhold. If an employee does not submit one, the IRS requires withholding as if they were single with no adjustments.
- [New hire reporting](/glossary/new-hire-reporting/). Not a form the employee fills in, but a federal requirement: employers must report new hires to their state directory of new hires within 20 days of hire, used mainly for child support enforcement. Some states set shorter deadlines.
E-Verify is federal too, but only required for some employers, such as federal contractors with an E-Verify clause and private employers in states that mandate it.
Common state forms
State requirements vary widely. The usual categories:
- State income tax withholding forms, in states with an income tax. Some states accept the federal W-4; many have their own form.
- Wage notices. Some states require a written notice at hire stating pay rate, payday and employer details. California's Labor Code section 2810.5 notice and New York's pay notice under the Wage Theft Prevention Act are well-known examples.
- Required state notices and pamphlets, such as workers' compensation, paid sick leave, disability insurance or paid family leave information.
- Local forms for city or county taxes in some areas.
When you hire in a new state, build a state-specific add-on to your standard packet rather than sending everyone every form.
Company and payroll documents
Beyond what the law requires, most employers collect:
- Signed offer letter and, where used, employment agreement, confidentiality agreement or arbitration agreement
- Direct deposit authorization (some states restrict requiring direct deposit, so offer an alternative)
- Emergency contact form
- Employee handbook and key policy acknowledgments (code of conduct, anti-harassment, IT acceptable use, attendance)
- Benefits enrollment forms, usually within a set window such as 30 days after the start date
- Voluntary self-identification forms for EEO reporting, which must be optional and kept separate from personnel files
- Background check disclosure and authorization, usually collected before or with the offer
- Job-specific items such as license copies, uniform size or equipment sign-out

A worked example: paperwork at volume
A staffing agency places 300 light industrial workers a month across Texas, Georgia and Illinois. Paperwork used to happen on paper at the branch on the worker's first day, and about one in ten new hires reached their first paycheck with a missing W-4, a wrong bank number or no direct deposit form.
Branch manager Lisa Grant moves everything to a mobile packet sent by text the same day an assignment is accepted. The packet is assembled by state: Georgia workers get the state G-4 withholding form, Illinois workers get the IL-W-4, and Texas workers, with no state income tax, skip that step. Required document templates are signed electronically and stored automatically.
I-9 Section 2 still needs document review, so workers bring documents to a 10-minute branch appointment before their first shift. Within two months, more than 90% of packets are complete before day one, payroll errors on the first check drop sharply, and branch staff stop losing first mornings to clipboards.
Record keeping and storage
- I-9s: keep for three years after the date of hire or one year after employment ends, whichever is later. Many employers store them separately from personnel files so an inspection does not expose other records.
- W-4s and payroll records: the IRS generally expects employment tax records to be kept at least four years.
- Medical information: under the ADA, any medical records, including drug test results and accommodation paperwork, must be kept confidential and in a separate file.
- EEO self-identification: keep separate from anything the hiring manager can see.
- Personnel records: EEOC rules generally require keeping them at least one year, and state law often requires longer.
Retention rules vary by state, so check the longest applicable period before deleting anything.
Common mistakes
- Waiting until day one. Most forms can be completed after offer acceptance. Leaving them all to the first morning wastes paid time and invites errors.
- Collecting I-9 documents before the offer is accepted. Not allowed. Run it after acceptance.
- Asking for specific I-9 documents. Employees choose which acceptable documents to present. Requesting a particular one can be unlawful discrimination.
- Mixing medical and personnel records. Keep them separate.
- Using one packet for every state. You either miss state notices or bury people in irrelevant forms.
- No tracking. Without a dashboard of what is missing, recruiters chase paperwork by memory. Pair it with a preboarding workflow and reminders.
Frequently asked questions
What paperwork is required for a new hire?
In the US, every employer needs Form I-9 and Form W-4 for every employee, plus state new hire reporting within 20 days. Most states add their own withholding form and required notices. Employers typically also collect direct deposit, emergency contact, policy acknowledgments and benefits enrollment.
What is a new hire packet?
A new hire packet is the bundle of forms and information sent to a new employee: required tax and eligibility forms, company policies, benefits details and first-day information. Many employers now send it as an online packet with e-signatures.
Can new hire paperwork be completed before the first day?
Yes. Most forms, including I-9 Section 1, can be completed after the offer is accepted and before the start date. The employer's I-9 document review must be done within three business days of the start date.
What onboarding documents should be kept in a personnel file?
Offer letter, job description, signed policy acknowledgments, W-4 and payroll forms and performance records. Keep I-9s, medical information and EEO self-identification data in separate files.
Do new employees have to fill out a W-4?
Employees are expected to submit one. If they do not, the employer must withhold federal income tax as if the employee were single with no other adjustments.
