HR compliance isn't just a large-company problem. The Department of Labor, IRS, and EEOC regularly audit businesses with 2 to 50 employees — and the fines for violations that seem minor can reach five or six figures quickly.
This checklist covers every major federal HR compliance requirement, plus the state-specific issues most likely to catch small businesses off guard in 2025. Use it as an annual audit tool or a new-business setup guide.

1. Hiring & Onboarding Compliance
Most compliance problems start at hire. These are the federal requirements every employer must meet from day one.
🧾 New Hire Documentation
Form I-9 completed by end of Day 3Required for every employee. Must verify both identity and work authorization. Keep for 3 years from hire or 1 year after termination, whichever is longer.
Form W-4 collected before first paycheckEmployees must complete this for federal income tax withholding. New 2020 format required for all new hires.
State tax withholding formMost states have their own withholding form in addition to the W-4. Check your state's revenue department website.
State new hire reporting filed within required windowFederal law requires reporting new hires to your state within 20 days. Some states require faster — California is 20 days, Texas is 20 days, New York is within 20 days.
Written offer letter providedNot legally required federally, but strongly recommended. Protects you from at-will disputes and wage claims.
2. Payroll Compliance
Payroll violations are the most common — and most expensive — HR fines for small businesses. The FLSA alone generated over $274 million in back wages recovered from employers in 2024.
💰 FLSA & Wage Requirements
All employees paid at least federal minimum wage ($7.25/hour)Many states have higher minimums. California: $16/hour, New York: $16/hour, Washington: $16.28/hour. Your state rate overrides federal if higher.
Non-exempt employees receive 1.5x pay for hours over 40/weekThe most violated FLSA rule. "Non-exempt" means anyone who doesn't meet the salary AND duties test for exemption.
Salaried exempt employees earn at least $684/week ($35,568/year)This threshold was updated in 2024. Employees below this threshold cannot be classified as exempt regardless of their job duties.
Pay stubs provided with each paycheckRequired in most states. Must show hours worked, pay rate, deductions, and net pay. Requirements vary by state.
Payroll taxes deposited on timeFederal payroll taxes (Social Security, Medicare, federal income tax) must be deposited according to your deposit schedule — monthly or semi-weekly depending on your payroll size.
⚠️ High-Risk: Overtime Misclassification
If you have salaried employees who earn less than $35,568/year, they are not legally exempt from overtime — regardless of their title. This is one of the most common and costly FLSA violations, with average back-wage liability of $8,000–$15,000 per affected employee.
3. Worker Classification
The IRS and DOL have both intensified contractor misclassification enforcement since 2023. If you use 1099 contractors, this section is critical.
⚖️ Employee vs. Contractor
Applied the IRS 3-factor behavioral control test to all contractorsDo you control how the work is done (not just the result)? If yes, they're likely an employee.
Contractors work for multiple clients (not exclusively for you)Exclusive long-term arrangements are a major misclassification red flag.
Contractors use their own tools and set their own hoursIf you supply equipment and set their schedule, they're behaving like an employee.
1099-NEC filed for all contractors paid over $600/yearDue January 31 each year. Failure to file: $60–$310 per form penalty.
4. Required Labor Law Posters
Federal law requires you to display specific posters in your workplace. Missing posters can result in fines up to $35,000 per violation — and they're checked during any DOL audit.
📌 Federal Posters Required for All Employers
FLSA / Federal Minimum Wage posterFree download at dol.gov. Must be displayed where employees can see it.
FMLA poster (if 50+ employees)Required if you have 50 or more employees. Free from DOL.

EEO "Know Your Rights" poster (if 15+ employees)Updated 2023 version required. Free from EEOC.gov.
State-specific posters displayedEvery state has additional required posters. Download free from your state's labor department website.
5. Employee Handbook
An employee handbook isn't legally required by federal law — but it's one of the most powerful tools you have to defend against wrongful termination claims, harassment allegations, and wage disputes. Employers with documented policies win employment disputes at a significantly higher rate.
📘 Handbook Must-Have Policies
At-will employment statementCritical in most states. Without this, terminations are harder to defend.
Anti-harassment and discrimination policyRequired by Title VII if you have 15+ employees. Best practice for all employers.
Leave policies (PTO, sick leave, FMLA)Must reflect your actual practice and comply with any applicable state leave laws.
Pay practices and overtime policyHow and when employees are paid, how overtime is calculated and approved.
Handbook acknowledged in writing by all employeesA signed acknowledgment is your proof the employee received and read the policies.
Reviewed by employment attorney or updated in last 24 monthsLaws change. A handbook that was compliant in 2022 may have gaps in 2025.
6. Leave Law Compliance
🏥 Federal Leave Requirements
FMLA policy in place (if 50+ employees)Up to 12 weeks of unpaid, job-protected leave for qualifying reasons. Applies to employees within 75 miles of a location with 50+ employees.
ADA reasonable accommodation process documented (if 15+ employees)Must have a process to evaluate accommodation requests. Ignoring requests is itself a violation.
Additionally, 14 states now mandate paid sick leave, and 11 states have paid family and medical leave programs. Check your state's requirements — this is the fastest-changing area of employment law right now.
7. Recordkeeping Requirements
📁 Records You Must Keep (and for How Long)
Payroll records: 3 years minimumHours worked, wages paid, pay rates, deductions. FLSA requirement.
I-9 forms: 3 years from hire or 1 year post-terminationWhichever is later. Must be produced within 3 business days of an ICE audit request.
