Key Takeaways
- Complete Form I-9, Form W-4, and applicable state withholding forms before the employee’s first payroll run.
- Submit the required new hire report to your state within the applicable reporting deadline.
- Provide required state-specific notices and benefit enrollment information during the onboarding process.
- Confirm the employee’s classification, pay rate, pay schedule, and payroll deductions before the first paycheck.
The excitement of a signed offer letter tends to fade fast once the actual onboarding paperwork lands on your desk. Miss one piece of it, and you’re not just disorganized, you’re potentially out of compliance before the new employee even finishes their first week.
A complete new hire checklist includes verifying work eligibility, collecting tax withholding forms, reporting the hire to your state, setting up payroll, and providing any legally required notices, all before or during the employee’s first pay period. Here’s the full list, in order.
Before day one
-
Verify work eligibility with Form I-9
Every new employee must complete Form I-9 within three business days of their start date, and you’re required to review original identity and work authorization documents in person or through an authorized remote verification process. This applies to every employee, regardless of citizenship status.
-
Collect Form W-4
Form W-4 determines how much federal income tax to withhold from the employee’s paycheck. Have this completed and on file before the first payroll run, since without it, you’re required to withhold at the default single-filer rate, which is rarely what the employee actually wants.
-
Collect state withholding forms, if applicable
Many states require a separate state withholding form in addition to the federal W-4. Confirm your state’s specific requirement before the first pay period.
-
Set up direct deposit
Collect bank account and routing information if the employee wants direct deposit, which most employees expect as the default payment method.
Within the first few days
-
Submit a new hire report to your state
Most states require employers to report new hires to a state directory, typically within 20 days of the start date, though the exact window varies by state. This isn’t optional, states use new hire reporting to enforce child support orders and detect unemployment insurance fraud.
-
Provide required notices
Depending on your state, new employees may need to receive specific written notices at hire, covering things like pay rate, pay schedule, workers’ compensation coverage, or paid sick leave policies. These requirements vary significantly by state, so check what applies in your jurisdiction specifically.
-
Enroll the employee in benefits, if applicable
If your business offers health insurance, retirement plans, or other benefits, provide enrollment materials and any required waiting period information during this window.
Setting up payroll for the new employee
-
Confirm classification
Confirm the employee is correctly classified as exempt or non-exempt under the Fair Labor Standards Act, which determines whether they’re eligible for overtime pay. This classification depends on job duties and salary level, not job title.
-
Set pay rate and schedule
Confirm the employee’s pay rate and how it aligns with your company’s existing pay schedule, whether weekly, biweekly, semimonthly, or monthly.
-
Add the employee to your payroll system
Enter the employee’s W-4 elections, pay rate, and any benefit deductions into your payroll system before the first pay run, so withholding calculates correctly from the very first paycheck.

Common onboarding mistakes
-
Processing the first paycheck before the W-4 is collected, resulting in incorrect withholding that needs to be corrected later
-
Missing the new hire reporting deadline, which can carry state-specific penalties
-
Misclassifying exempt vs. non-exempt status, which creates overtime liability that surfaces later, often during an audit or complaint
-
Skipping state-specific notices, assuming federal requirements cover everything
Why the order matters
Onboarding isn’t just a list of tasks to complete whenever convenient, several pieces are legally time-bound, and some depend on others being completed first. Form I-9 has a hard three-day deadline. New hire reporting has its own separate window. Payroll withholding depends on having a completed W-4 in hand before the first calculation happens, not after.
Treating onboarding as a sequence rather than a checklist to complete in any order is what keeps a new hire’s first weeks compliant, instead of becoming a cleanup project a few pay periods in.
Every item on this checklist is a step PayWow builds directly into onboarding. From W-4 and I-9 collection to new hire state reporting, PayWow keeps your first pay run compliant from day one.
