Worker Misclassification Risk Assessment Calculator

Evaluate whether a worker may be misclassified as an independent contractor using IRS common-law rules, the ABC Test, and DOL economic reality factors. Answer each question to receive a risk score and classification guidance.

Behavioral Control

Financial Control

Type of Relationship

ABC Test Factors (used in many states)

Scoring Formula

Weighted Risk Score (%) = (Σ answer_value_i × weight_i) / (Σ 2 × weight_i) × 100

Each question is scored 0 (contractor indicator), 1 (neutral), or 2 (employee indicator) and multiplied by its factor weight. The sum is divided by the maximum possible weighted score to produce a 0–100% risk percentage.

Category weights: Behavioral Control (instructions ×2.0, schedule ×1.5, location ×1.0); Financial Control (investment ×2.0, profit/loss ×2.0, market services ×2.0, payment method ×1.5); Relationship Type (benefits ×2.0, permanency ×1.5, integral work ×2.0, substitution ×1.5, written contract ×1.0); ABC Test (direction ×2.0, outside business ×2.0, independent trade ×2.0).

Risk Bands: 0–24% = Low Risk | 25–49% = Moderate Risk | 50–74% = High Risk | 75–100% = Very High Risk

Assumptions & References

  • Based on IRS Publication 15-A (Employer's Supplemental Tax Guide) common-law rules: behavioral control, financial control, and type of relationship.
  • Incorporates the ABC Test used by California (AB5/Labor Code §2750.3), Massachusetts, New Jersey, and other states for worker classification.
  • Reflects U.S. Department of Labor (DOL) "economic reality" test factors under the Fair Labor Standards Act (FLSA).
  • IRS penalties for misclassification: IRC §3509 provides reduced rates (1.5% income tax + 20% employee FICA) for non-intentional misclassification; full rates apply for intentional violations.
  • No single factor is determinative; the IRS and courts examine the totality of the relationship.
  • State rules vary significantly — California's ABC Test is among the strictest; other states use different standards.
  • This calculator does not account for industry-specific safe harbors (e.g., Section 530 relief) or prior audit history.
  • Results are for educational/risk-awareness purposes only and do not constitute legal, tax, or HR advice.
