The three-part test that decides who counts as a contractor in California

California's AB 5, enacted in September 2019 under Governor Gavin Newsom and championed by Assemblywoman Lorena Gonzalez, created a legal presumption that all workers are employees unless a business can prove otherwise using the ABC test. This standard is the strictest in the country and applies across most industries and types of work. The law was designed to provide wage, overtime, and benefits protections to gig economy workers—estimated at about a million Californians—but its scope extended far beyond ride-sharing to retailers, media companies, manufacturers, and professional services firms.

The rule operates as a burden-of-proof reversal. Instead of workers proving they are employees, businesses must prove workers qualify as independent contractors by satisfying all three parts of the ABC test. A business that fails to satisfy all three criteria must classify the worker as an employee, triggering obligations for minimum wage, overtime pay, paid leave, workers' compensation, and payroll taxes. The law carries significant enforcement teeth. The California Labor Commissioner has issued millions in penalties across hospitality, logistics, home care, and transportation sectors. Compensation thresholds for exempt professions adjust annually—in 2026, the computer professional threshold rose to $122,573 annually—and exemptions themselves periodically expand or change.

The presumption of employment and why AB 5 exists

Before AB 5, California courts had applied the Borello test, a flexible standard that allowed businesses significant latitude in classifying workers as independent contractors. The gig economy companies—particularly Uber and Lyft—used this flexibility to classify drivers as contractors despite controlling many aspects of their work. AB 5 replaced this flexibility with the ABC test, a framework borrowed from wage-and-hour law that requires stricter proof of independence.

The shift changes incentive structures. Under the Borello test, a business could argue that a worker had some discretion in their work even if the company controlled rates, scheduling, and customer assignment. Under the ABC test, courts do not weigh factors—they require proof of all three conditions. Meeting two out of three is not enough; the worker becomes an employee. This standard applies across the state regardless of company size or industry, affecting businesses with contract workers from Fortune 500 companies to sole proprietors. The law even applies to out-of-state companies hiring California workers.

The three parts of the ABC test: Control, scope, and independence

Criterion A requires that a worker be free from the control and direction of the hiring entity in performing the work, both in writing and in practice. This means the business cannot direct how, when, or where work gets done. A typical employment relationship involves substantial direction; independent contractors operate with genuine autonomy. If a business requires specific procedures, set hours, regular management check-ins, or approval of completed work before payment, it is likely exercising too much control. The test examines both the contract and actual practice—a contract claiming independence while practice shows control will fail this prong.

Criterion B asks whether the work falls outside the usual course of the hiring entity's business. A retail store hiring a plumber for a repair satisfies this test; a bakery hiring cake decorators for regular decoration work does not, since decorating is central to the bakery's operations. A clothing manufacturer hiring seamstresses to sew dresses from company-supplied cloth and patterns fails this prong. The work must genuinely fall outside the company's typical operations. This criterion prevents businesses from outsourcing their core work under the pretense of contractor relationships.

Criterion C requires that the worker be customarily engaged in an independently established trade or business of the same nature as the work being performed. The business must already exist when work begins—not potentially exist later. The worker should advertise services publicly, maintain their own business location, serve multiple clients, and not rely on a single hiring entity for income. This prong recognizes that true independent contractors run businesses that serve many customers. A worker who only works for one company does not meet this standard. California courts have emphasized that the worker's independent business must actually be established and operating at the time work begins.

How exemptions work and which professions qualify

California exempts roughly 100 professions from the ABC test, though exemption status does not automatically grant independent contractor classification—a critical distinction many businesses misunderstand. When a profession is exempt, courts apply the older Borello test instead of the ABC test. This test is more flexible, examining factors like control, skill level, permanence of the relationship, and whether the parties intended an independent contractor arrangement. Even for exempt professions, a worker can still be classified as an employee if the Borello test indicates genuine employment.

Licensed professionals including doctors, lawyers, accountants, architects, engineers, dentists, psychologists, veterinarians, and private investigators are exempt. Real estate agents, insurance agents and brokers, and securities brokers registered with the SEC, FINRA, or the State of California qualify for exemptions. Creative and media professionals including writers, editors, photographers, graphic designers, fine artists, and freelance journalists are also exempt from the ABC test. Musicians, music producers, sound engineers, and photographers for music marketing shoots fall under the exemption. Licensed manicurists, barbers, cosmetologists, and electrologists qualify for exemptions.

For these exempt professions, the burden remains on the business to document that the worker qualifies. An attorney cannot be classified as a contractor simply because attorneys are exempt; the business must still show that the Borello test's factors support contractor status. This distinction has created confusion. Many businesses identify a contractor on the exempt list and assume the classification is settled, only to discover that exemption status moved the worker out of the ABC test but did not guarantee contractor classification.

2026 updates: Threshold increases and exemption extensions

Effective January 1, 2026, California raised the compensation threshold for the computer professional exemption to $122,573.13 annually ($10,214.44 monthly or $58.85 per hour). This represents a 3.3 percent increase from 2025's threshold of $118,657.43 annually and reflects California's Consumer Price Index inflation. Computer professionals earning below this threshold cannot qualify for the exemption regardless of other factors, and must be evaluated under the ABC test. This annual adjustment means businesses must monitor threshold changes each January to ensure continued compliance.

AB 1514, effective January 1, 2026, extended the exemption for licensed manicurists through December 31, 2028 and commercial fishers through December 31, 2030. The law also adjusted exemption definitions for certain creative, consulting, and technology-service roles. These refinements specified which types of creative work and consulting services qualify for exemptions but did not alter the fundamental ABC test or extend exemptions to construction trades, which remain explicitly subject to the strict test. The legislative pattern shows California continues fine-tuning exemptions while maintaining the ABC test's core structure.

Financial costs and compliance burden for businesses

The financial impact of misclassification is substantial. When a business reclassifies a contractor as an employee, the total cost increases significantly. For a worker earning $30,000 annually as a contractor, the annual cost as an employee rises to $37,500 to $42,000 when accounting for payroll taxes, workers' compensation insurance, health insurance, and paid leave. Multiply this across hundreds or thousands of workers and the cost becomes transformative. This financial reality has driven significant business reorganization across California—companies have restructured workforces, changed contractor agreements, and entered litigation challenging the law.

Compliance requires businesses to document their analysis of each worker classification against all three ABC criteria. Retaining written records of control arrangements, work scope, and evidence of the worker's independent business becomes critical should enforcement action occur. Businesses also face exposure to class action litigation; workers or labor agencies challenging misclassification often pursue claims on behalf of multiple workers, multiplying liability. Beyond the statutory $5,000–$25,000 per violation penalties, businesses owe back wages, unpaid overtime, meal and rest break premiums, and interest to any worker determined to be misclassified.

Enforcement penalties and recent cases

Labor Code section 226.8 imposes civil penalties for willful misclassification: $5,000 to $15,000 per violation when a court or agency determines misclassification has occurred. For a pattern or practice of misclassification, penalties escalate to $10,000 to $25,000 per violation. These statutory penalties often prove modest compared to the underlying wage liability. Beyond these amounts, businesses owe back wages to the misclassified worker, unpaid overtime and meal break premiums, interest on unpaid wages, unpaid payroll taxes, and workers' compensation assessments. Class action lawsuits are common in misclassification disputes, allowing workers to pursue claims on behalf of similarly situated coworkers.

Recent enforcement demonstrates broad sectoral reach and serious consequences. In February 2025, the California Labor Commissioner cited Amity In-Home Care Services $2.3 million for misclassifying caregivers as independent contractors. In late 2024, the Labor Commissioner issued roughly $868,000 in penalties against three companies—Mega Nice Trucking, Ryder Last Mile, and Costco—for misclassifying drivers. These actions show enforcement has expanded well beyond ride-sharing to hospitality, logistics, home care, and transportation. The Labor Commissioner's office has signaled that enforcement will continue across industries, making compliance a priority for any California business using contract workers.

What this means for California employers and hiring decisions

Business owners and hiring managers need to assess worker classification carefully against all three ABC criteria. Meeting one or two parts of the test is not enough. Many common hiring arrangements—temporary workers, freelancers, consultants, specialists—end up requiring employee classification under AB 5, which can significantly increase labor costs and administrative burden. Managers cannot simply call a worker a contractor; they must document why each prong of the ABC test is satisfied or will face penalties and wage liability.

For businesses that have long relied on contractor workforces, AB 5 has forced significant restructuring. Some have converted contractors to employees. Others have reorganized work so that remaining contractors genuinely satisfy all three prongs—working independently for multiple clients outside the company's usual business. Still others have relocated work or operations outside California. The competitive pressure is real: a California business bearing the cost of employee classification while competitors in other states use contractors faces a meaningful cost disadvantage. This dynamic has fueled ongoing debate and occasional legislative adjustments like the exemptions extended through AB 1514.
