Employee Classification

ABC Test

California's three-pronged test under AB5 for determining whether a worker is an employee or independent contractor.

What Is the ABC Test?

The ABC test is California's standard for determining whether a worker is an employee or an independent contractor. Codified through Assembly Bill 5 (AB5) and now part of California Labor Code Section 2750.3, the ABC test creates a strong presumption that workers are employees.

Under the ABC test, a worker is presumed to be an employee unless the hiring entity can prove ALL THREE of the following conditions are met. If the hiring entity fails to prove even ONE prong, the worker is legally an employee entitled to all protections under California law.

The Three Prongs of the ABC Test

Prong A: Autonomy (Free from Control)

The worker must be free from the control and direction of the hiring entity in connection with the performance of the work, both under the contract for the performance of the work and in fact.

What This Means:

  • The hiring entity cannot control HOW the work is performed
  • The worker sets their own schedule
  • The worker determines their own methods and processes
  • Independence exists both in writing AND in practice
Control Factor Employee Indicator Contractor Indicator
Schedule Company sets hours Worker sets own hours
Location Required to work on-site Chooses where to work
Methods Must follow procedures Determines approach
Equipment Uses company tools Provides own tools
Training Required company training Already has skills
Supervision Regular oversight Works independently
Appearance Uniform or dress code No appearance requirements

Example - Passes Prong A: A graphic designer who accepts a project, determines their own approach, works from their home office on their own schedule, and delivers the finished product by an agreed deadline.

Example - Fails Prong A: A graphic designer who must work on-site 9-5, attend daily meetings, follow company design guidelines, use company software, and have work approved by a supervisor at each stage.

Prong B: Business (Outside Usual Course)

The worker must perform work that is outside the usual course of the hiring entity's business.

What This Means:

  • The work must be different from what the company normally does
  • Work that is integral to the business fails this prong
  • If employees do similar work, the worker should be an employee too

This is often the most difficult prong to satisfy and represents a significant departure from previous independent contractor tests.

Hiring Entity OUTSIDE Business (May Pass) INSIDE Business (Fails)
Restaurant Accountant doing taxes Chef preparing food
Law firm Plumber fixing pipes Attorney handling cases
Trucking company IT consultant Driver making deliveries
Retail store Electrician rewiring Sales associate
Software company Security guard Programmer writing code
Hospital Landscaper Nurse treating patients
Marketing agency Cleaning service Copywriter creating content
Construction company Caterer for event Carpenter building structures

Example - Passes Prong B: A bakery hires an electrician to install new lighting. Electrical work is outside the bakery business.

Example - Fails Prong B: A bakery hires a "freelance" baker to make bread. Baking IS the bakery's business.

Prong C: Customarily (Independently Established)

The worker must be customarily engaged in an independently established trade, occupation, or business of the same nature as the work performed for the hiring entity.

What This Means:

  • The worker has a real, existing independent business
  • The business was established BEFORE this engagement
  • The business operates APART from this relationship
  • The worker has evidence of independent enterprise
Factor Employee Indicator Contractor Indicator
Business structure No formal business LLC, corporation, or DBA
Other clients Works only for one company Multiple clients
Marketing No advertising or website Active marketing presence
Business expenses No overhead or investments Insurance, licenses, office
Industry reputation Unknown in field Established reputation
How acquired Recruited by company Found through own marketing
Risk of loss No financial risk Can profit or lose

Example - Passes Prong C: A licensed plumber with their own business, multiple clients, business insurance, a company truck, and a website—who accepts a job at a restaurant.

Example - Fails Prong C: A former employee who "became" a contractor doing the same work for the same company, with no other clients, no business structure, and no marketing.

Applying the ABC Test: Complete Analysis

Step-by-Step Process

Step 1: Gather information about the working relationship

  • Review all contracts and agreements
  • Examine actual working conditions
  • Interview relevant parties

Step 2: Analyze Prong A

  • Does the company control how work is done?
  • Is there a set schedule?
  • Are methods dictated?

Step 3: Analyze Prong B

  • What is the company's primary business?
  • Is this work integral to that business?
  • Do employees do similar work?

Step 4: Analyze Prong C

  • Does the worker have an independent business?
  • Are there other clients?
  • What evidence exists of independent enterprise?

Step 5: Reach conclusion

  • If ALL THREE prongs are satisfied → May be independent contractor
  • If ANY prong fails → Worker is an employee

Decision Flowchart

START: Is this worker an independent contractor?
  │
  ├─ PRONG A: Is worker free from control?
  │     │
  │     ├─ NO → Worker is EMPLOYEE
  │     │
  │     └─ YES → Continue to Prong B
  │
  ├─ PRONG B: Is work outside usual business?
  │     │
  │     ├─ NO → Worker is EMPLOYEE
  │     │
  │     └─ YES → Continue to Prong C
  │
  └─ PRONG C: Has worker established independent business?
        │
        ├─ NO → Worker is EMPLOYEE
        │
        └─ YES → May be INDEPENDENT CONTRACTOR

Exemptions from the ABC Test

AB5 includes exemptions for specific occupations and business relationships. When an exemption applies, the older "Borello" test is used instead:

Professional Services Exemptions

Licensed architects State architecture license
Licensed engineers State engineering license
Licensed accountants (CPAs) CPA license
Licensed insurance agents State insurance license
Securities broker-dealers FINRA registration
Investment advisers SEC or state registration
Direct sales Meets statutory definition

The Borello Test (When Exemptions Apply)

When an exemption applies, California uses the Borello test from S.G. Borello & Sons v. Department of Industrial Relations (1989). This is a multi-factor balancing test:

Primary Factor

  • Right to control work details (most important)

Secondary Factors

Factor Analysis
Right to discharge Can end relationship at will?
Skill required Specialized expertise needed?
Who provides tools Company or worker?
Work location Where is work performed?
Duration Length of services
Payment method By time or by project?
Part of regular business Integral to operations?
Parties' belief How do parties view relationship?
Principal's business Is hiring entity in business?

The Borello test is more flexible than the ABC test and considers the totality of circumstances.

Best Practices for Compliance

Before Engaging a Worker

  1. Apply the ABC test to every independent contractor relationship
  2. Check for exemptions that might apply
  3. Document your analysis in writing
  4. When in doubt, hire as employee - it's the safer path

Structuring Contractor Relationships

Do Don't
Define specific deliverables Create open-ended engagements
Allow contractor to set schedule Require specific hours
Let contractor determine methods Dictate how work is done
Verify other clients exist Require exclusivity
Use project-based contracts Create ongoing relationships
Require contractor's own tools Provide equipment

Ongoing Monitoring

  • Review contractor relationships annually
  • Watch for "drift" toward employment characteristics
  • Reclassify when circumstances change
  • Train hiring managers on ABC test requirements
