New hire paperwork is one of those tasks that feels simple until you realize you've missed a required form and now you're non-compliant. Different states, different industries, different roles—each adds complexity.
This guide gives you a complete checklist of every piece of paperwork you need to collect, organized by category. Use it as your master template to ensure nothing falls through the cracks.
Before Day One
Send paperwork before their start date whenever possible. New hires can complete it at home, and day one can focus on actual onboarding instead of filling out forms.

Federal Forms (Required)
These forms are required by federal law for all U.S. employers. Non-compliance can result in fines, so don't skip these.
Form W-4: Federal Tax Withholding
Employee's Withholding Certificate
Determines how much federal income tax to withhold from each paycheck. The employee declares their filing status, number of dependents, and any additional withholding.
Timeline: Before first paycheck
Must be completed before you process their first paycheck. If not submitted, you must withhold at the highest rate (single, no adjustments).
Where to get it:
IRS.gov or your payroll provider
Form I-9: Employment Eligibility Verification
Proof of Work Authorization
Verifies that the employee is legally authorized to work in the United States. Requires physical inspection of original documents (passport, driver's license + Social Security card, etc.).
Timeline: Within 3 business days of hire
Section 1 must be completed by the employee on or before day one. Section 2 (document verification) must be completed by the employer within 3 business days of the start date.
Critical Notes:
- • Must physically examine original documents (no copies or photos)
- • Remote workers: Special rules apply. Check USCIS guidance.
- • Keep I-9s for 3 years after hire OR 1 year after termination (whichever is later)
- • Store separately from personnel files
Where to get it:
USCIS.gov (official source)
Form W-9: Taxpayer Identification (Contractors Only)
Request for Taxpayer Identification Number
For independent contractors (1099 workers), not W-2 employees. Collects their SSN or EIN for tax reporting purposes.
Timeline: Before first payment
Required before you pay them. If you pay $600+ during the year, you'll need this info to file 1099-NEC.
Where to get it:
IRS.gov
Federal Form Summary
- • W-4: All employees (before first paycheck)
- • I-9: All employees (within 3 days of hire)
- • W-9: Independent contractors only (before first payment)
State Requirements
State requirements vary significantly. Here are the most common categories you'll encounter:
State Tax Withholding Forms
Similar to Federal W-4, but for state income tax:
Most states require their own withholding certificate
Examples: California DE 4, New York IT-2104, Massachusetts M-4
9 states have no income tax (and don't require state forms)
Alaska, Florida, Nevada, New Hampshire, South Dakota, Tennessee, Texas, Washington, Wyoming
Check if the employee works in a different state than your company is based
Remote workers may trigger tax obligations in their state of residence
New Hire Reporting
Required in ALL 50 states
Every state requires employers to report new hires to the state Directory of New Hires. This helps enforce child support orders.
Timeline: Within 20 days of hire (varies by state)
Some states require reporting within 7 days. Check your state's requirements.
Information required: Name, address, SSN, start date
Can usually be submitted online or by fax
Most payroll providers automate this
Gusto, ADP, Paychex all handle new hire reporting automatically
State-Specific Forms
Some states require additional forms:
California
- • Notice to Employee - Labor Code 2810.5 (wage and employment info)
- • Sexual harassment training acknowledgment
- • Paid sick leave notice
New York
- • Notice and Acknowledgment of Pay Rate and Payday (LS 54)
- • Paid sick leave notice
- • Deduction authorization (if applicable)
Massachusetts
- • Earned sick time notice
- • Wage and hour notice
How to Find Your State's Requirements
Every state's Department of Labor website lists required new hire forms. Search "[Your State] new hire forms" or consult your payroll provider—they usually have state-specific checklists.
If you use a modern payroll service (Gusto, Rippling, ADP), they'll often auto-generate required state forms.
Company Documents
Beyond legal requirements, your company needs signed acknowledgments and agreements to protect both parties.
Essential Company Documents
Offer Letter (signed copy)
Keep a signed copy for your records. Should include: title, start date, salary/wage, benefits summary, at-will statement (if applicable).
Employee Handbook Acknowledgment
Employee confirms they've received, read, and understand the handbook. Protects you if policies are violated later.
Code of Conduct / Ethics Policy
Acknowledgment of workplace behavior expectations, harassment policy, conflict of interest rules.
At-Will Employment Agreement
If in an at-will state, clarify that employment can be terminated by either party at any time, for any legal reason.
Confidentiality & IP Protection
Especially important for tech, creative, and professional services companies:
Non-Disclosure Agreement (NDA)
Protects confidential company information, trade secrets, and customer data. Consider separate NDAs for particularly sensitive roles.
Intellectual Property Assignment Agreement
Clarifies that work created during employment belongs to the company. Critical for developers, designers, writers, and inventors.
Non-Compete / Non-Solicitation Agreement
Restricts employee from working for competitors or poaching clients/employees after leaving. Note: enforceability varies by state. Some states (like California) ban non-competes almost entirely.
Technology & Security
Acceptable Use Policy for Company Technology
Rules for using company email, devices, software. Clarify monitoring rights.
Data Security & Privacy Acknowledgment
Especially important if handling customer data, HIPAA, or PCI compliance.
Remote Work Agreement (if applicable)
Expectations for remote work: hours, communication, equipment, workspace security.
Industry-Specific Requirements
- • Healthcare: HIPAA training and compliance acknowledgment
- • Finance: FINRA registration, background check authorization
- • Education: Background checks, TB test, fingerprinting
- • Transportation: Drug testing consent, motor vehicle record check
Benefits Enrollment
If you offer benefits, enrollment paperwork is a beast of its own. Here's what you'll need:
Health Insurance
Enrollment form (employee + dependents)
Employee selects plan tier, adds dependents, provides SSNs for covered individuals
Beneficiary designations
Who receives benefits if employee dies
Waiver of coverage (if declining)
If employee declines coverage, document it. Protects against later claims they weren't offered insurance.
COBRA notice (if applicable)
If 20+ employees, you must provide COBRA rights notice within 90 days of coverage start
Retirement Plans (401k, etc.)
Enrollment election form
Contribution percentage, Roth vs. Traditional election
Investment selection
Which funds to invest in (often done online through plan provider)
Beneficiary designation
Primary and contingent beneficiaries
Auto-enrollment notice (if applicable)
If you auto-enroll at a default rate, disclose this and provide opt-out instructions
Other Benefits
Life Insurance & AD&D
Enrollment form, beneficiary designation, evidence of insurability (if coverage exceeds guaranteed issue amount)
Disability Insurance (Short & Long Term)
Enrollment election, medical questionnaire (if not guaranteed issue)
FSA / HSA
Annual election amount, account setup. HSA requires eligible high-deductible health plan.
Commuter Benefits
Pre-tax election for parking or transit
Benefits Enrollment Windows
New hires typically have 30 days from their start date to enroll in benefits. After that window, they usually must wait until open enrollment (unless they have a qualifying life event like marriage or birth).
Make the deadline crystal clear. Missing it means they're uninsured for months.
Payroll & Banking Setup
You need this information to pay your new hire correctly and on time.
Required for Payroll
Direct Deposit Authorization
Bank name, account number, routing number. Most employees expect direct deposit.
Alternative: Issue paper checks (but this is increasingly rare and inconvenient)
Salary/Wage Verification
Confirm pay rate, pay frequency (weekly, bi-weekly, semi-monthly, monthly)
Should match offer letter
Exempt vs. Non-Exempt Classification
Determines overtime eligibility under FLSA
Misclassification is a common source of wage & hour violations
Pay Stub Delivery Preference
Electronic (email/portal) or printed
Time Tracking (if applicable)
For non-exempt (hourly) employees:
Time clock / timesheet training
How to clock in/out, submit hours, request time off
Break and meal period policy
State laws vary on required breaks. Document that employee understands policy.
Overtime authorization process
Can they work overtime without approval? Make expectations clear.
Additional Payroll Deductions
Voluntary Deductions
401k contributions, health insurance premiums, HSA/FSA, life insurance, union dues
Garnishments
Child support, tax liens, student loan defaults. Usually initiated by government order, not employee.
Deduction Authorization Form
Get written consent for any non-required deductions. Protects against wage disputes.
Compliance Timelines
Different forms have different deadlines. Miss them and you risk fines. Here's your timeline:
Pre-Start Date
W-4, state tax forms, direct deposit
