A signed contractor agreement does not make someone an independent contractor under California law. Neither does Form 1099.

California's ABC test presumes every worker is an employee by default. The burden falls entirely on the hiring entity to prove all three conditions of the test are satisfied. And unlike many legal standards, the ABC test allows no partial credit: fail any single prong, and the worker is an employee under California law, regardless of what any agreement says.

Most California employers who rely on independent contractors have never analyzed their arrangements against all three prongs. Prong B, which requires the work to fall outside the company's core business, is the one most often failed without the employer knowing it.

Why Does California Treat Worker Classification Differently From Federal Law?

California's worker classification standard is codified in Labor Code sections 2775 through 2787 through Assembly Bill 5, which took effect on January 1, 2020. AB 5 built on the California Supreme Court's 2018 decision in Dynamex Operations West, Inc. v. Superior Court, which first established the ABC test for worker classification.

Under the ABC test, the hiring entity bears the full burden of proving that a worker qualifies as an independent contractor. If the hiring entity cannot prove all three conditions, the worker is an employee under California law, including the California Labor Code, the Unemployment Insurance Code, and applicable wage orders.

This standard is significantly stricter than the federal approach. Under the Fair Labor Standards Act, regulators use an economic realities test that evaluates the overall nature of the working relationship using multiple factors. In May 2025, the U.S. Department of Labor issued Field Assistance Bulletin 2025-1, reverting to a more employer-friendly version of that test after pausing enforcement of its 2024 independent contractor rule.

What Did the 2025 Federal Shift Actually Change for California Employers?

Nothing. California's ABC test is state law, codified in the California Labor Code. It operates entirely independently of federal regulatory guidance. The DOL bulletin affects federal enforcement by the DOL and does not modify what the California EDD, the Labor Commissioner, or California courts apply to California workers.

California employers who heard that contractor rules are being relaxed and assumed that change extends to their California operations are working from a misconception that could prove expensive. The ABC test is unchanged, California enforcement continues, and PAGA remains fully available to misclassified workers in California.

How Does the ABC Test Work? Understanding All Three Prongs

Under California's ABC test, a worker is presumed to be an employee unless the hiring entity can prove all three of the following conditions are satisfied.

A worker who satisfies all three conditions may be properly classified as an independent contractor. A worker who fails even one condition is an employee under California law. The label in the contract means nothing if the actual working relationship tells a different story. Employers dealing with worker classification disputes face wage and hour liability under California law that includes not just back wages but missed meal and rest break premiums, overtime, and PAGA penalties that compound per pay period across every similarly classified worker.

Prong A: Is the Worker Free From Your Control?

Prong A asks whether the worker is free from the control and direction of the hiring entity, both under the terms of the contract and in actual practice.

The key distinction is between controlling the outcome of the work and controlling the manner in which it is performed. A hiring entity can specify what result it wants and when a project should be complete without necessarily crossing into Prong A territory. But dictating work hours, requiring specific methods, mandating the use of company tools or uniforms, or directly supervising the worker's daily tasks are behaviors that point toward an employment relationship.

In practice, Prong A is not the prong where most California employers run into problems. Prong B is.

Prong B: Does the Worker Perform Work Outside Your Core Business?

Prong B requires that the worker performs work outside the usual course of the hiring entity's business. This is the prong where most California employer-contractor arrangements break down, and the one that generates the most misclassification liability.

"Usual course of business" means the work the company actually does to generate revenue. If an HVAC company in San Diego classifies its installation and repair technicians as independent contractors, those workers perform the core work of the business. Prong B fails. The technicians are employees under California law regardless of what any contractor agreement says.

If that same HVAC company classifies its bookkeeper as a contractor, Prong B may be satisfied. Bookkeeping is not what the HVAC company does to earn revenue.

The practical test is direct: does the worker perform the same type of work the company sells or provides to customers? If yes, Prong B fails and the classification will not survive scrutiny before the Labor Commissioner, the EDD, or a PAGA plaintiff. This analysis should happen before any contractor arrangement is entered into, not after a notice arrives.

Prong C: Does the Worker Run an Independent Business?

Prong C asks whether the worker is customarily engaged in an independently established trade, occupation, or business of the same nature as the work performed.

A contractor who satisfies Prong C has an existence in the market that is independent of their relationship with the hiring entity. They hold their own business license or entity. They serve multiple clients. They set their own rates. They market their services to others. They supply their own tools and equipment.

A worker who operates exclusively for one company, under conditions set by that company, without any independent market presence will typically fail Prong C. The contractor label in the agreement is not evidence of Prong C compliance. The worker's actual business structure and independent market activity is.

Have You Actually Tested Prong B?

If your contractors do the work you sell, they may already be employees.

Most owners have never run their arrangements against all three prongs, and Prong B fails quietly. Karin Backstrom will review your contractor relationships as they actually operate and tell you which ones hold up, before the Labor Commissioner or a PAGA plaintiff runs the same test.

What Are the Exemptions, and When Does the Borello Test Apply?

The Borello test is the multi-factor standard California applies when a worker's occupation qualifies for a statutory exemption from the ABC test. Where an exemption applies, the worker is evaluated under the Borello standard rather than the stricter ABC test.

The Borello test focuses primarily on the hiring entity's right to control the manner and means of performing the work. It also considers additional factors including whether the worker operates a distinct business, whether the work requires special skill, the method of payment, and the length of the working relationship. The Borello test is more flexible and generally more employer-friendly than the ABC test, which is why most exemptions are significant for the industries they cover.

Exemptions from the ABC test cover a range of industries and professions. Key categories include licensed professionals (physicians, dentists, lawyers, architects, engineers, accountants, veterinarians, and certain other licensed professionals), real estate agents and mortgage loan originators meeting specific criteria, certain financial services professionals, licensed insurance agents and brokers, certain creative professionals including some freelance writers and photographers subject to submission limits, referral agency workers in specified service categories, and construction subcontractors holding a valid California contractor's license and meeting specific additional requirements.

Assembly Bill 1514, effective January 1, 2026, extended two narrow exemptions from the ABC test: licensed manicurists through January 1, 2029, and commercial fishers working on American vessels through January 1, 2031. These are industry-specific extensions, not a broad relaxation of AB 5 or the ABC test.

An exemption does not automatically grant contractor status. Workers in exempt categories are still evaluated under the Borello test, and the hiring entity must still demonstrate that the working relationship qualifies as independent contractor status under that standard.

The Business-to-Business Exemption

One of the most practically useful exemptions for California employers is the business-to-business exception. This exemption allows a business entity to contract with another business entity as an independent contractor outside the ABC test, provided both parties satisfy a specific and demanding set of conditions.

To use the B2B exemption, the contracting relationship must meet all required conditions, including that the contractor must be a genuine business entity rather than an individual, must hold an active business license, must carry its own business liability insurance, must maintain its own client base and market its services to others beyond the single hiring entity, must set its own rates and work terms, and must provide its own tools and equipment.

The B2B exemption is not a workaround available to any worker who forms an LLC. Every condition must be genuinely satisfied in practice, not just on paper. An employment defense attorney can assess whether a specific contractor arrangement qualifies before the hiring entity relies on this exemption.

What Are the Consequences of Getting Worker Classification Wrong?

Worker misclassification in California can trigger liability for unpaid wages, payroll tax penalties, workers' compensation exposure, and PAGA civil penalties that compound per pay period across every similarly classified worker in the company.

That last part matters more than most California employers realize. PAGA, the Private Attorneys General Act, allows a single misclassified worker to file a representative action on behalf of all aggrieved employees. In a misclassification context, that means all workers classified the same way as the one who filed. PAGA penalties are assessed per pay period, per aggrieved employee, per violation type. Working with a PAGA defense attorney California employers trust is the starting point for assessing this exposure honestly before a notice or lawsuit arrives.

Consider what that looks like for a San Diego construction company that has classified eight subcontractors as independent contractors for three years, paid bi-weekly. That is approximately 78 pay periods over the lookback window. If Prong B fails for those workers, each pay period is a potential PAGA violation for each of the eight workers. Before adding missed overtime, missed meal break premiums, and unreimbursed expenses, the math across the workforce is significant. Multiple violation types stacking per pay period can reach six figures before the case ever reaches a courtroom.

Beyond PAGA, the Employment Development Department audits employer payroll tax compliance and can independently assess unpaid employer contributions to unemployment insurance, unpaid State Disability Insurance contributions, unpaid Employment Training Tax, and personal income tax withholding penalties. The California Labor Commissioner handles individual wage claims and can require payment of back wages, overtime, meal and rest break premiums, and unreimbursed business expenses. Workers' compensation exposure also becomes an issue if a misclassified worker sustains an injury on the job.

Misclassification also removes protections workers are entitled to under California law. A worker improperly classified as a contractor is denied California's meal break and rest period protections, and each missed break across the lookback period becomes a separate PAGA violation on top of the classification error itself.

Misclassification in California is not a paperwork problem. It is a financial liability that accumulates retroactively across a workforce, across every pay period in the lookback window, and across every violation type simultaneously.

One Misclassified Role, a Whole-Workforce Bill

Fix the classification on your terms, not the Labor Commissioner's.

A single failed prong multiplies across every similarly classified worker and every pay period in the lookback, before overtime, break premiums, and EDD penalties stack on top. Karin audits your arrangements, documents a defensible position, and builds the reasonable-steps record that limits exposure if a claim comes.

What Steps Should California Employers Take to Reduce Misclassification Risk?

The most effective time to identify a misclassification problem is before a PAGA notice or an EDD audit notice arrives. The steps below give California employers a practical starting point.

  1. Audit your existing contractor relationships against all three prongs of the ABC test and document the analysis in writing. If Prong B fails for any current contractor, that arrangement requires immediate attention.
  2. Review every contractor agreement to confirm it accurately reflects the actual working relationship, not just the preferred one. Courts and agencies look at how the work actually happens, not what the contract says.
  3. For each contractor, verify they genuinely operate as an independent business. They should serve multiple clients, set their own rates, hold their own business license or entity, and provide their own tools and equipment.
  4. Do not direct contractors' work hours, methods, or day-to-day tasks. Limit instructions to the outcome and the delivery timeline.
  5. If your business falls into an exempt category under AB 5, confirm every specific exemption condition is fully satisfied and document that compliance in writing. An exemption applies only when all required conditions are met in practice.
  6. File the EDD Report of Independent Contractors, Form DE-542, for each contractor paid $600 or more in a calendar year. Failure to file this form carries a separate penalty.
  7. If you have received a PAGA notice, a Labor Commissioner wage claim, or an EDD audit notice involving a contractor, contact California employer-defense counsel the same day. Response windows are short, and early decisions in those proceedings affect the entire trajectory of the matter.

Employers who want to conduct this audit correctly and build the documentation record that supports a defensible classification position will find that proactive HR compliance guidance for worker classification is substantially less expensive than defending a misclassification claim after it has been filed.

The contractor arrangement that looked defensible on paper may fail Prong B entirely once a Labor Commissioner auditor reviews the actual working relationship. Auditing before a claim arrives costs a fraction of defending one.

Frequently Asked Questions

The ABC test is California's three-part standard for determining whether a worker is an employee or an independent contractor. Under the test, a worker is presumed to be an employee unless the hiring entity can prove all three conditions: the worker is free from the hiring entity's control, performs work outside the company's usual course of business, and is customarily engaged in an independently established trade or occupation. All three conditions must be satisfied simultaneously. Failing any one means the worker is an employee under California law, regardless of the agreement between the parties. The California Department of Industrial Relations provides additional guidance on California's worker classification framework and how the ABC test applies across different industries and occupations.
No. California courts and enforcement agencies look at the actual working relationship, not what the contract says. A worker who performs core business functions under the company's direction can be found to be an employee regardless of any contractor label or signed agreement. The contract is relevant evidence, but it is not determinative. The ABC test requires the employer to prove the real-world relationship satisfies all three conditions.
Prong B requires that the worker performs work outside the usual course of the hiring entity's business. It is the prong most California employers fail because many use contractors to perform the same type of work the company provides to its own customers. A landscaping company that classifies its crew members as contractors fails Prong B because landscaping is the company's core business. A landscaping company that classifies its accountant as a contractor likely satisfies Prong B. The test is not about the job title. It is about whether the work falls inside or outside what the company does to generate revenue.
Penalties can include back wages and overtime, missed meal and rest break premiums, unreimbursed business expenses, payroll tax penalties assessed by the EDD, workers' compensation exposure, and PAGA civil penalties that compound per pay period across all similarly classified workers. California Labor Code penalties can also apply per misclassified employee per violation. The aggregate exposure across a workforce of misclassified workers over a multi-year period can reach six figures or more for smaller California employers.
In May 2025, the U.S. Department of Labor paused enforcement of its 2024 independent contractor rule and reverted to the older economic realities standard under the Fair Labor Standards Act. This change affects federal enforcement by the DOL only. California's ABC test is state law and is not affected by federal regulatory guidance. California employers remain subject to the same ABC test codified in Labor Code sections 2775 through 2787, and the 2025 DOL shift provides no protection in EDD audits, Labor Commissioner proceedings, or PAGA lawsuits filed in California courts. The U.S. Department of Labor's Wage and Hour Division provides information on federal independent contractor standards under the FLSA, which apply separately from California's ABC test framework.
The business-to-business exemption allows a genuine business entity to contract with another business as an independent contractor outside the scope of the ABC test. To qualify, the contractor must be a business entity rather than an individual, hold an active business license, carry its own liability insurance, serve multiple clients beyond the single hiring entity, set its own rates and conditions, and operate independently in the market. Every condition must be satisfied in actual practice. A worker who simply forms an LLC to work for one company under that company's direction will not qualify. The B2B exemption still requires evaluation under the Borello test.
