Worker Classification: 1099 vs W-2

Answer the questions below to understand whether a worker should be classified as an employee (W-2) or independent contractor (1099).

Compliance Requirements

Critical Co-Employment

What it is: Co-employment occurs when both the staffing firm and the client exercise sufficient control over a worker to be considered joint employers.

Why it matters: Both parties can be held liable for wages, benefits, discrimination claims, workplace safety violations, and labor law compliance.

How to mitigate:

  • Clear MSA language defining employer responsibilities
  • Staffing firm handles all HR functions (hiring, firing, discipline, pay)
  • Client doesn't include contingent workers in benefits or company events
  • Separate badging, email domains, and org chart treatment
  • Regular compliance audits and tenure policies (typically 18-24 month limits)
Critical Worker Classification (1099 vs W-2)

What it is: The legal determination of whether a worker is an employee (W-2) or independent contractor (1099). Different tests apply at federal, state, and local levels.

Key tests:

  • IRS 20-Factor Test: Evaluates behavioral control, financial control, and relationship type
  • ABC Test (CA AB5): Worker is employee unless free from control (A), work is outside usual business (B), and worker has independent business (C)
  • Economic Reality Test (DOL): Focuses on economic dependence

Penalties for misclassification: Back taxes + penalties (up to 100%), back wages and benefits, state fines ($5K-$25K per worker), potential criminal charges.

Important Affordable Care Act (ACA)

What it is: Federal law requiring Applicable Large Employers (50+ FTE) to offer affordable health insurance to full-time employees (30+ hours/week).

Impact on staffing: Staffing firms must track variable-hour employees using lookback measurement periods (typically 12 months) to determine eligibility. This is one of the largest components of the burden rate for longer-term assignments.

Key provisions:

  • Employer Shared Responsibility Payment: $2,970/employee if coverage not offered
  • Lookback measurement method for variable-hour workers
  • IRS Form 1094-C/1095-C reporting requirements
  • Coverage must be "affordable" (employee cost <9.12% of household income)
Important SOX Compliance

What it is: Sarbanes-Oxley Act requires public companies to maintain accurate financial records and internal controls over financial reporting.

Impact on staffing: Contingent labor spend must be properly tracked, approved, auditable, and reported. This drives the need for VMS systems and purchase order requirements.

Key requirements:

  • All spend must have proper approvals and documentation
  • Segregation of duties (requestor ≠ approver)
  • Audit trail for all transactions
  • Timely invoice processing and accrual reporting
Compliance OFCCP & Diversity

What it is: The Office of Federal Contract Compliance Programs enforces equal opportunity and affirmative action for federal contractors. Diversity requirements extend to supplier selection in staffing programs.

Key requirements:

  • Affirmative Action Plans (AAP) for federal contractors
  • EEO-1 reporting requirements
  • Supplier diversity targets (typically 15-30% diverse spend)
  • Diversity certifications: MBE, WBE, VBE, SDVOB, LGBTBE, DOBE
  • Tracking and reporting diverse candidate slates
Compliance Data Privacy & Security

What it is: Staffing firms handle sensitive PII (Social Security numbers, background checks, medical information). Multiple regulations apply.

Key regulations:

  • CCPA/CPRA (California): Right to know, delete, and opt-out of data sale
  • GDPR (EU workers): Consent-based processing, data portability, right to erasure
  • FCRA: Fair Credit Reporting Act governs background checks
  • HIPAA: Protects medical information for healthcare staffing
  • SOC 2: Security controls certification (required by many enterprise clients)
