How should employers classify employees versus contractors?

Classifying Employees vs. Contractors in Missouri

Proper classification of workers as employees or independent contractors is critical for Missouri businesses to ensure compliance with tax, payroll, and labor regulations.

Key Operational Factors for Classification

• Control Over Work: Employees typically work under the direction and control of the employer regarding how, when, and where tasks are performed. Contractors have more autonomy in completing their work.
• Financial Control: Employees often receive regular wages or salaries, while contractors are paid per project or contract and may incur their own business expenses.
• Relationship Nature: Employees usually have ongoing, indefinite relationships with the employer, including benefits and company policies. Contractors work on specific projects or periods without employee benefits.
• Tools and Equipment: Employees generally use employer-provided tools and resources. Contractors typically supply their own equipment.

Missouri-Specific Operational Considerations

• Payroll and Tax Withholding: Employers must withhold Missouri state income tax, Social Security, Medicare, and unemployment taxes for employees. Contractors handle their own tax obligations.
• Unemployment Insurance: Employee wages are subject to Missouri unemployment insurance contributions. Payments to contractors are not.
• Workers’ Compensation: Employees must be covered under Missouri workers’ compensation insurance. Contractors are generally responsible for their own coverage.
• Recordkeeping: Maintain clear documentation supporting classification decisions, including contracts, work schedules, and payment records.

Best Practices for Missouri Employers

• Use Written Agreements: Clearly outline the nature of the relationship, payment terms, and responsibilities in contracts with contractors.
• Review IRS Guidelines: Follow the IRS’s three-factor test (behavioral control, financial control, and relationship) to guide classification decisions.
• Consult Missouri Labor Resources: Stay updated with Missouri Department of Labor and Industrial Relations on classification rules and compliance requirements.
• Implement Payroll Systems: Use payroll software that accurately handles employee tax withholdings and contractor payments separately.
• Regularly Audit Classifications: Periodically review worker classifications to adjust for changes in work arrangements or regulations.

As of 2026, maintaining accurate classification supports compliance with Missouri tax reporting, payroll, insurance, and labor regulations, reducing risk of penalties and audits.
