Exhaustive Guide to US Worker Classification and Payroll Tax Law

Overview of Worker Classification Categories

Worker classification is a critical determination for tax and legal purposes, primarily distinguishing between employees and independent contractors. The IRS defines several specific categories that dictate how taxes are withheld and reports are filed.

  • Common Law Employee (also known as Employee):

    • An individual who performs services for an employer.
    • Level of Authority: An employer is classified as such if they have the authority to control what tasks will be completed, how those tasks should be carried out, and provide the necessary tools and equipment for the job.
    • Example Job: Shop assistant.

  • Independent Contractor:

    • Professionals who offer their services independently to the public.
    • Financial Terms: Employers pay a contracted rate for services but do not control how the work is designed or performed, nor do they provide tools or equipment.
    • Example Jobs: Lawyers, contractors, and auctioneers.
    • Economic Risk: These workers often take financial risks, meaning they have the potential to either profit or sustain a loss.

The Common Law Test

The IRS uses the common law test to examine the relationship between a business and a worker to determine their classification. This test focuses on the degree of control and independence across three specific categories:

  • Behavioral Control:

    • Determined by asking whether the company tells the worker when and where to work or how the work is to be performed.
    • If the company dictates these factors (when, where, how), uses the company’s tools, and provides training, the individual is likely an employee.

  • Financial Control:

    • Focuses on who assumes the financial risks of the operation.
    • Employees are generally paid for the time worked regardless of the company's financial health, meaning the company bears the risk.
    • Independent contractors typically cover their own business expenses and have the opportunity for profit or loss.

  • Type of Relationship:

    • This functions as a "catch-all" for factors not covered by behavioral or financial categories.
    • Factors include:
      1. Written contracts between the parties.
      2. Employee benefits offered (e.g., insurance, pension plans, paid vacation).
      3. The permanency of the relationship.
      4. Whether the services provided are a key (integral) aspect of the business.

Statutory Classifications: Exceptions to Common Law Rules

Certain occupations have specific tax treatments regardless of common law outcomes. These are divided into statutory employees and statutory nonemployees.

  • Statutory Employees:

    • Treated as employees for Social Security, Medicare, and Federal Unemployment Tax (FUTA) purposes (W-2 workers).
    • Criteria for categories:
      1. Drivers distributing beverages (other than milk), produce, or other foods.
      2. Full-time traveling or city salespeople.
      3. Home-based workers who create goods (e.g., jewelry makers, textile workers) from materials provided by the employer which must be returned to the employer.
      4. Full-time life insurance sales agents.

  • Statutory Nonemployees:

    • Treated as independent contractors for tax purposes with no employment taxes withheld (1099 workers).
    • Categories include:
      1. Certain companion sitters.
      2. Licensed real estate agents.
      3. Direct sellers of consumer products.

Economic Reality Test (ERT)

The US Department of Labor (DOL) uses the Economic Reality Test under the Fair Labor Standards Act (FLSA) to classify workers. This test considers six non-weighted factors to look at the "overall circumstances":

  1. Opportunity for Profit or Loss: Depending on managerial skill.
  2. Investments: Comparing the worker’s investment to the employer’s investment in the business.
  3. Permanence: The duration and nature of the work relationship.
  4. Nature and Degree of Control: How much control the employer exercises.
  5. Integrality: Whether the work performed is an integral part of the employer’s business.
  6. Skill and Initiative: Whether the worker uses specialized skills and business-like initiative.

The ABC Test (State-Level)

Many states use the "ABC test" to determine worker status for matters such as unemployment compensation, workers' compensation, and state taxes. A worker is considered an independent contractor only if all three following criteria are met:

  • A - Lack of Control: The worker operates independently without supervision and shows autonomy in execution.
  • B - Nature of Work: The work is unusual for the organization or performed off-site (outside normal business operations).
  • C - Independent Business Engagement: The worker is regularly engaged in an independently established trade, occupation, or business.

Official Determination: IRS Form SS-8

If there is confusion or a dispute regarding worker classification, both workers and businesses can file Form SS-8 (Determination of Worker Status for Purposes of Federal Employment Taxes and Income Tax Withholding). The IRS will review the facts and provide a formal decision used for filing federal income and employment tax returns.

Case Study: Artemis (Martin) Bernard at Glass Studio

  • Context: A glass studio hired Martin Bernard (referred to as Artem in technical discussion), a non-citizen and winner of a global amateur glass design competition, as their first Chief Design Officer.
  • Application of Common Law Test: The studio determined the worker was an employee because they have the right to control the work and the results, and the worker is not in business for themselves offering services to the public.
  • Application of Economic Reality Test:
    • Nature and Degree of Control: Artem is the "primary driver" of glass designs for the foreseeable future.
    • Integrality: The design work is an "incredibly important part" of the organization.
  • Compensation Thresholds for Highly Compensated Employees (HCE):
    • To be considered highly compensated, the employee must be paid a total annual compensation of $107,432\$107,432 or more.
    • This must include at least $684\$684 per week paid on a salary or fee basis.
  • Tax Impact: As an employee, the studio must withhold payroll taxes regularly.

Questions & Discussion

Scenario: Taylor is hired by Steel River Towing to maintain grounds. Taylor is paid a set amount regardless of hours, uses their own equipment, controls the schedule and methodology, and offers services to other businesses.

  • Question: What type of worker is Taylor likely to be considered?
  • Answer: Independent Contractor.
  • Rationale: The employer (Steel River Towing) lacks control over the "when" and "how" of the work, and Taylor operates an independent business (offering services to others), which aligns with the independent contractor classification.
