Classifying workers correctly is one of the more consequential decisions a California business makes, and the rules have changed significantly in recent years. Misinformation is common, and treating a worker as an independent contractor when the law considers them an employee can lead to serious financial and legal exposure. The current framework centers on a strict test with a small set of exemptions, and understanding it is the difference between a defensible arrangement and a costly one.
How Worker Classification Changed in California
For years, California relied on the Borello test, a flexible, multi-factor standard focused mainly on how much control a business exercised over a worker. That changed in 2018, when the California Supreme Court’s Dynamex decision replaced Borello for many purposes with a strict three-part standard known as the ABC test, later written into law through Assembly Bill 5. The most important shift was the burden of proof. Under the ABC test, a worker is presumed to be an employee unless the hiring business can prove otherwise. It also helps to separate state and federal rules, since they operate independently. The IRS examines behavioral control, financial control, and the nature of the relationship for tax purposes, while California’s ABC test is more rigid and is aimed specifically at extending employee protections under state wage orders.
Common Misclassification Myths
Several assumptions lead businesses astray. The first is that a signed independent contractor agreement settles the question. Courts look at the actual working relationship rather than the paperwork, so directing a worker’s hours, supplying their tools, and controlling how the work is done can establish employee status regardless of what a contract says. A second assumption is that tax classification determines labor classification. A worker can receive a 1099 for federal tax purposes and still be an employee under California labor law, because the state tests apply no matter how taxes are filed. A third assumption is that flexibility rules out employment. Allowing a worker to set their own hours or work remotely does not make them a contractor if the conditions of the ABC test are not met.
The Three Prongs of the ABC Test
To classify a worker as an independent contractor in California, a business must satisfy all three prongs of the ABC test. The first requires that the worker be free from the control and direction of the hiring business in performing the work. The second requires that the work fall outside the usual course of the hiring business, so a bakery that hires a plumber meets this prong while a bakery that hires a cake decorator does not. The third requires that the worker be customarily engaged in an independently established trade or business of the same nature as the work performed. Failing even one prong means the worker is an employee under the law.
Exemptions Under AB 5
Not every occupation falls under the ABC test. The law has been amended repeatedly to add carve-outs, and exempt professionals, including doctors, lawyers, accountants, real estate agents, and certain freelance writers, are instead evaluated under the older Borello standard. A separate business-to-business exemption exists, but its requirements are strict. To qualify, the service provider must operate as a genuinely distinct business, maintain its own separate location, and market its services to the public, among other conditions. Even a properly classified contractor retains certain rights under California labor law, including control over their own schedule, the ability to work for multiple clients, and ownership of their own business processes.
What Misclassification Can Cost
California enforces these rules aggressively, since misclassification can deprive workers of minimum wage, overtime, and workers’ compensation. A business under scrutiny may face an audit by the Employment Development Department, which examines payroll records, 1099 filings, and contracts. Penalties for willful misclassification are significant and can run from several thousand dollars to tens of thousands of dollars per violation. The larger risk is often retroactive liability, because a business found non-compliant can be required to pay years of back taxes, unpaid overtime, missed break penalties, and retroactive workers’ compensation premiums, an accumulation that has pushed some smaller companies into bankruptcy.
Reducing Misclassification Risk
Proactive review is the best protection. That starts with an honest audit of every current independent contractor, evaluating each one against the three prongs of the ABC test rather than against the label on their contract. Where a worker might qualify for a professional or business-to-business exemption, the applicable Borello factors should be checked as well. Contracts should reflect how the relationship actually functions, and day-to-day practices should reinforce contractor status rather than undercut it, which means not issuing company email addresses, employee handbooks, or direct managerial supervision to genuine contractors. Because these laws continue to evolve, periodic review with an employment attorney or qualified specialist helps keep classifications current.
Getting Classification Right
Worker classification in California rewards accuracy over assumptions. The ABC test sets a high bar, the exemptions are narrow and specific, and the consequences of getting it wrong reach back over years. A business that measures each worker against the actual legal standard, and revisits those judgments as the law changes, can build the flexible workforce it needs while staying within the rules.
