A compliant new employee onboarding checklist covers work authorization, tax withholding, new hire reporting, required notices and postings, day-one training, benefits disclosures, and record retention — each with its own deadline. Miss one and the penalties start at hundreds of dollars per violation and climb from there. The steps below run in the order the deadlines fall, from the employee’s first day forward.
Set Up the Employer Accounts First
Before anyone starts, you need an Employer Identification Number from the IRS. It’s free, you can get it online in minutes, and it appears on nearly every employment tax form and government report you file.1Internal Revenue Service. Get an Employer Identification Number
You also need federal and state unemployment tax accounts. Federal unemployment tax runs at a net rate of 0.6% on the first $7,000 of each employee’s annual wages, assuming your state qualifies for the standard credit.2U.S. Department of Labor. FUTA Credit Reductions Each state sets its own unemployment tax rate for new employers. And nearly every state requires workers’ compensation insurance once you have employees, though the employee-count triggers and exemptions vary. Confirm your state’s rule before the first day of work.
Complete Form I-9 Within Three Business Days
Federal law makes it illegal to hire anyone without verifying their identity and authorization to work in the United States. Form I-9 must be completed for every new hire, including U.S. citizens.3eCFR. 8 CFR 274a.2 – Verification of Identity and Employment Authorization The form has two parts with firm deadlines:
- The employee completes Section 1 on or before their first day of work for pay, attesting to citizenship or immigration status.
- You examine the employee’s original identity and work-authorization documents and complete Section 2 within three business days of the hire date.3eCFR. 8 CFR 274a.2 – Verification of Identity and Employment Authorization
Acceptable documents fall into three lists printed on the form. One List A document (like a U.S. passport or permanent resident card) proves both identity and work authorization. Otherwise, the employee presents one List B document (identity) plus one List C document (work authorization). You cannot tell the employee which documents to present.
Remote Document Examination
Employers enrolled in E-Verify at all hiring sites may use an alternative procedure that allows remote document review. The employee transmits copies, and you examine them in a live video interaction — still within three business days of the start date.4Federal Register. Optional Alternative to Physical Document Examination for Employment Eligibility Verification Check the box on the I-9 indicating the alternative procedure was used and keep clear copies of the documents.
Collect a W-4 and State Withholding Form
Every employee completes IRS Form W-4 so you can calculate federal income tax withholding.5Internal Revenue Service. About Form W-4, Employees Withholding Certificate The current form asks for filing status, dependent credits, and any additional income or deductions that would adjust the standard withholding.6Internal Revenue Service. Form W-4 (2026) – Employees Withholding Certificate If the employee doesn’t turn one in, withhold at the default rate of single with no adjustments.
Most states with an income tax require a separate state withholding certificate. Eight states — Alaska, Florida, Nevada, New Hampshire, South Dakota, Tennessee, Texas, and Wyoming — have no state income tax. Everywhere else, either the federal W-4 doubles as the state form or the state uses its own document. Check your state tax agency’s current form before the first payroll.
Federal law does not require you to give new hires a written wage notice listing their pay rate and schedule, but many states do. These wage notice or wage theft prevention laws typically require a written document at hire showing the rate of pay, pay frequency, and overtime rate, with per-employee penalties for failure to provide it.
Report the Hire to the State Within 20 Days
Federal law requires you to report every new hire to your state’s Directory of New Hires, primarily to help locate parents who owe child support. The report includes your company name, address, and EIN, plus the employee’s name, address, and Social Security number.7GovInfo. Personal Responsibility and Work Opportunity Reconciliation Act of 1996
The federal deadline is 20 calendar days from the hire date. States that accept electronic or magnetic filings may allow two monthly transmissions instead.7GovInfo. Personal Responsibility and Work Opportunity Reconciliation Act of 1996 Most states offer a secure online portal. The penalty for failing to report can be up to $25 per employee, or up to $500 where the employer and employee conspire not to report.8Administration for Children and Families. New Hire Reporting – Answers to Employer Questions
E-Verify, Only Where It Applies
E-Verify cross-checks I-9 information against government records. Participation is mandatory for federal contractors and for employers in certain states, and voluntary for everyone else. If you use it, create a case for each new hire no later than the third business day after the employee starts work for pay.9E-Verify. 2.2 Create a Case The system either confirms eligibility or issues a tentative nonconfirmation, which requires you to notify the employee and allow them a chance to resolve the discrepancy.
Post Required Labor Law Notices
Federal law requires several workplace posters displayed where employees can see them. The Department of Labor administers posting rules for the Fair Labor Standards Act, the Family and Medical Leave Act, and the Employee Polygraph Protection Act, among others, and offers a free poster package and an online advisor tool that identifies which posters apply based on your size and industry.10U.S. Department of Labor. Workplace Posters
The EEOC separately requires covered employers to display the “Know Your Rights” poster covering workplace discrimination protections; employers that fail to post it are subject to fines.11U.S. Equal Employment Opportunity Commission. EEOC Releases Updated Know Your Rights Poster OSHA has its own workplace safety poster. Most states pile on additional requirements, so check your state labor department for a complete list.
Deliver Training Before the Employee Is Exposed to the Hazard
OSHA standards require certain training before or immediately upon initial job assignment. What you owe depends on the hazards in your workplace, but several rules apply broadly:
- Emergency action plans must be reviewed with each employee when they’re first assigned to a job.
- Fire prevention plans require employees to be informed of role-relevant fire hazards on initial assignment.
- Hazard communication training is required at the time of initial assignment if hazardous chemicals are present in the work area.
- Powered industrial trucks (forklifts and similar equipment) cannot be operated until the employee has completed the required training.
These come from various sections of 29 CFR 1910 for general industry and 29 CFR 1926 for construction.12Occupational Safety and Health Administration. Training Requirements in OSHA Standards The common rule is that training must happen before exposure, not weeks later. Document every session with dates, topics covered, and employee signatures.
A growing number of states also require sexual harassment prevention training for new employees. Where required, training generally runs one hour for staff and two hours for supervisors, with completion deadlines typically between six months and one year after the hire date.
Send Benefits Notices on Time
If you offer a group health plan, retirement plan, or other benefit covered by ERISA, onboarding triggers specific disclosure deadlines. Provide each new participant with a Summary Plan Description — the plain-language document explaining benefits, rights, and how to file a claim — within 90 days of the date they become a participant in the plan.13Office of the Law Revision Counsel. 29 U.S. Code 1024 – Filing With Secretary and Furnishing Information
If your group health plan is subject to COBRA, furnish the general notice of continuation coverage rights to the employee and their covered spouse within 90 days of the date coverage begins.14eCFR. 29 CFR 2590.606-1 – General Notice of Continuation Coverage The notice explains that if the employee later loses coverage due to a qualifying event, they may continue the plan at their own expense. A separate general notice to dependent children isn’t required.
Many employers also set an internal enrollment window, often 30 or 60 days from hire, after which the employee has to wait for open enrollment. Communicate that deadline clearly so the new hire doesn’t forfeit coverage by accident.
Handbook Acknowledgment and Accommodation Requests
Walk the new hire through the employee handbook covering attendance, dress code, anti-harassment standards, data privacy, and use of company technology. If you use non-disclosure or confidentiality agreements, present those for signature during this phase. Have the employee sign a written acknowledgment confirming they received the handbook and had a chance to ask questions. A digital signature works the same as paper. The acknowledgment doesn’t create a contract, but it does create a record that the employee was informed of company policies — useful if a dispute arises later.
If a new hire discloses a disability and requests an accommodation during onboarding, whether for a modified training format, assistive technology, or an adjusted schedule, you’re required to engage in an informal, interactive process to identify an appropriate solution. This obligation covers all aspects of employment, including employer-sponsored orientation and training.15U.S. Equal Employment Opportunity Commission. Enforcement Guidance on Reasonable Accommodation and Undue Hardship Under the ADA Examples include providing materials in large print, arranging a sign language interpreter, or allowing extra time on training modules. Ignoring or delaying a request can create liability for failure to accommodate.
Keep the Records
The most specific federal retention rule applies to the I-9: keep each completed form for either three years after the hire date or one year after the employee leaves, whichever is later.3eCFR. 8 CFR 274a.2 – Verification of Identity and Employment Authorization You can store forms on paper, electronically, or on microfilm, as long as they’re readily available if a government agency asks to inspect them.
W-4 forms should be retained for as long as they’re in effect and for at least four years after the tax becomes due or is paid, under general IRS recordkeeping rules. Signed handbook acknowledgments, benefits enrollment records, and training logs don’t have a single federal retention period, but keeping them for the length of employment plus several years afterward is standard practice and protects you in an audit or lawsuit.
What Non-Compliance Costs
Federal law establishes escalating civil penalties for I-9 violations, with separate penalty tiers for paperwork errors and for knowingly hiring someone not authorized to work.16Office of the Law Revision Counsel. 8 USC 1324a – Unlawful Employment of Aliens Amounts adjust annually for inflation, and repeat offenses climb sharply. A single paperwork violation can cost hundreds of dollars; knowingly hiring unauthorized workers can run into the thousands per employee.
New hire reporting penalties are smaller: capped at $25 per unreported employee under federal law, rising to $500 where the failure results from a conspiracy between employer and employee.8Administration for Children and Families. New Hire Reporting – Answers to Employer Questions Missing required posters can draw fines from the DOL, EEOC, or OSHA, depending on which one you skipped. Beyond direct fines, weak onboarding documentation undermines your position in any later dispute, from wage claims to wrongful termination suits.
