HR Compliance Checklist 2026: Every Requirement by Company Size (10, 50, 100+ Employees)
TL;DR: HR Compliance by Headcount
- 10–14 employees: State-level wage/hour laws only (no federal trigger).
- 15+ employees: ADA, Title VII (race, color, religion, sex, national origin), ADEA (age 40+), EEOC filing.
- 20+ employees: COBRA continuation coverage (if group health plan exists).
- 50+ employees: FMLA (unpaid leave), WARN Act (60-day layoff notice), ACA tracking/reporting.
- 100+ employees: EEO-1 filing, stricter DOL audit exposure.
- All sizes: State wage/hour, anti-discrimination, harassment policies, tax withholding, recordkeeping.
Deadline check: All compliance tiers must be current as of July 1, 2026. Audit your policies now.
What is HR compliance and why does company size matter?
HR compliance means following federal, state, and local employment laws. Most federal requirements trigger at specific employee thresholds—the IRS and Department of Labor count part-time workers (1000+ hours/year) and contractors toward headcount in some contexts. This checklist organizes obligations by size so you know when obligations kick in.
The 15-employee threshold is the most critical: once you cross it, Title VII, ADA, ADEA, and EEOC jurisdiction all apply. Below 15, you still have state compliance duties.
HR Compliance for 10–14 Employees: State and Local Requirements
At this size, you're not yet subject to federal anti-discrimination laws, but state laws still apply.
Immediate requirements:
- Wage and hour compliance (state minimum wage, overtime, meal breaks). California, Massachusetts, and New York have stricter rules than federal FLSA.
- Written anti-harassment and anti-discrimination policy (required in many states, even pre-15 employees).
- State payroll tax withholding and employer contributions.
- Workers' compensation insurance (mandatory in all states).
- I-9 employment verification for all new hires.
- Notice posting (state-specific labor law posters in break rooms).
Document and save: Employment agreements, offer letters, payroll records (minimum 3 years), tax returns showing headcount. State labor boards audit small companies regularly—missing records can cost $1,000+ per violation.
What federal laws apply at 15+ employees?
Once you hit 15 employees, four major federal statutes apply:
- Title VII of the Civil Rights Act — prohibits discrimination based on race, color, religion, sex, or national origin. Includes harassment, retaliation, and pay equity.
- Americans with Disabilities Act (ADA) — requires reasonable accommodations for employees with disabilities. Interactive process required; documentation must be confidential.
- Age Discrimination in Employment Act (ADEA) — protects employees age 40+. "Replace with younger/cheaper talent" is illegal.
- EEOC jurisdiction — you can be sued in federal court for discrimination. A complainant files with EEOC first; the agency investigates. Prepare documentation.
Action items:
- Adopt a Title VII-compliant anti-discrimination and harassment policy. Include retaliation prohibition, complaint procedure, and investigation protocol.
- Document performance reviews and disciplinary actions (keep 3+ years). Termination decisions must be defensible: "performance" is legal; "too old" or "pregnant" is not.
- Train managers on harassment reporting (even informal reports count).
- Set up an ADA request process: employee says they need accommodation → you engage in interactive process → document decision.
What federal laws apply at 20+ employees?
COBRA (Consolidated Omnibus Budget Reconciliation Act)
If you offer a group health plan, departing employees (or their families) can elect continuation coverage for 18–36 months at full premium cost. You must send COBRA notices within 14 days of termination.
Cost: COBRA is expensive for the employee, but some will choose it. Non-compliance = Department of Labor fines of $100–300+ per day per failure.
Action: Audit your health plan documents. If you have health coverage, you need a COBRA administrator (often bundled with your health plan broker). Notify departing employees in writing.
What federal laws apply at 50+ employees?
Family and Medical Leave Act (FMLA)
Covered employers must allow 12 weeks of unpaid, job-protected leave per 12-month period for birth, adoption, serious illness (employee or family), military caregiver leave, or military exigency. This overrides any company policy that says "no unpaid leave."
Key rules:
- Employee must provide 30 days' notice (if foreseeable).
- Health insurance continues during FMLA leave (employer pays their share).
- Job must be available on return; no retaliation.
- Part-time employees count if they've worked 12 months + 1,250 hours.
WARN Act (Worker Adjustment and Retraining Notification)
If you lay off 50+ employees at one site within 60 days, you must notify workers 60 days in advance. Penalties: backpay + damages, often $30,000+ per violation.
Affordable Care Act (ACA) Reporting
By December 31, 2026, you must file Form 1095-C (health coverage provided) and Form 1094-C (transmittal) with the IRS. This tracks whether you offered adequate coverage and at what cost.
Action items:
- Create an FMLA policy (sample language available from DOL). Train HR and managers.
- Document intermittent leave carefully: a single day's absence might be FMLA-eligible.
- If planning layoffs, consult HR counsel 60+ days before announcement.
- Set up ACA forms tracking (often bundled with payroll/benefits admin).
What federal laws apply at 100+ employees?
EEO-1 Filing
Companies with 100+ employees must file the EEO-1 Component 1 form by March 31, 2027 (for 2026 data). This form categorizes employees by job category, race/ethnicity, and gender. The EEOC uses this to detect discrimination patterns.
Exposure: Audit findings can trigger enforcement actions.
OSHA Recordkeeping (if applicable)
Companies with 100+ employees in certain industries must report serious workplace injuries to OSHA.
Executive Compensation Proxy (if public)
If you're a public company with 100+ employees, you disclose executive pay (not directly an HR compliance issue, but affects talent agreements).
Action items:
- Ensure accurate job category data in your HRIS. "Job category" doesn't mean title—use DOL definitions (officials/managers, professionals, technicians, sales workers, administrative support, skilled crafts, operatives, laborers, service workers).
- Prepare EEO-1 data months in advance; don't scramble in March.
- Verify that your payroll/benefits system can generate this data correctly.
State Compliance Layer: Vary Widely
Federal law is the floor; states can (and often do) exceed it:
- Wage/hour: CA minimum wage $16.50/hour (2026); MA overtime rules stricter than federal; IL requires paid sick leave.
- Remote work: CA requires remote workers to have a safe workspace; WA mandates ergonomic assessments.
- Pay transparency: CA, IL, WA, and NY require salary ranges in job postings (no "competitive salary").
- Ban-the-box: Several states prohibit asking about criminal history on applications.
- Predictive scheduling: CA, WA, NY, Illinois regulate last-minute schedule changes.
Multi-state employer risk: If you operate in multiple states, you must comply with the strictest rule in each state where you have employees. For example, if you have one employee in California, California wage laws apply to that person, not federal minimums.
How to Implement Compliance: Five Steps
- Audit: Count employees (including part-time if 1,000+ hours/year). Identify which thresholds apply.
- Policy review: Update handbooks for ADA, FMLA, anti-harassment, wage/hour, leave (vacation, sick, bereavement).
- State check: List each state where you have employees. Cross-reference wage/hour, leave, and anti-discrimination requirements.
- Documentation: Implement templates for offer letters, performance reviews, disciplinary action, accommodation requests.
- Training: Annual manager training on harassment, retaliation, and lawful termination decisions.

Common Compliance Mistakes (and How to Avoid Them)
- Misclassifying independent contractors as employees → IRS audits; back payroll taxes + penalties.
- No FMLA policy, then denying leave → employee lawsuit; treble damages possible.
- Firing an employee shortly after they request ADA accommodation → prima facie retaliation case.
- Wage deductions for "breakage" or uniform costs → violates wage/hour laws in many states.
- Forgetting to send COBRA notice → DOL fine of $100–300/day.
