Before AB5, California contractor classification was governed by the Borello test, which is a multi-factor balancing framework that gave companies meaningful latitude to structure working relationships as independent contractor arrangements. Borello wasn't frictionless, but it was workable. The 2018 Dynamex decision changed the standard for wage-order claims, introducing the ABC test for that narrower scope. AB5, signed into law in September 2019 and effective January 1, 2020, took that decision and turned it into statute — broadening its application to the California Labor Code and the Unemployment Insurance Code, and codifying the presumption that every worker is an employee unless you can prove otherwise.

If you engage independent contractors who perform any work in California — regardless of where your company is headquartered — AB5 applies to you.

Key Takeaways

• AB5 applies the ABC test to most worker classification decisions in California, presuming employment unless all three prongs are satisfied.
• The law covers any work performed in California. If your contractor does work in the state, you're subject to AB5, regardless of where your company is based.
• Dozens of professions are exempt from the ABC test under AB5 and its follow-on legislation. Exempt workers are evaluated under the more flexible Borello test instead. Exempt does not mean automatically a contractor.
• Penalties for willful misclassification range from $5,000 to $25,000 per violation. That's before back taxes, benefits obligations, and civil claims. In California, PAGA exposure adds a per-violation, per-pay-period multiplier that can dwarf the underlying tax liability.
• California's ABC test is structurally stricter than the version used in most other states. Prong B, requiring that work fall outside the company's usual course of business, has no "place of business" alternative in California or Massachusetts. That distinction matters for multi-state contractor programs.

What Is California AB5 Law?

AB5 (formally California Assembly Bill 5) is the state law that governs how workers are classified as either independent contractors or employees. It was signed by Governor Gavin Newsom in September 2019 and took effect January 1, 2020.

The law codified the ABC test as the primary standard for determining worker classification under the California Labor Code, the Unemployment Insurance Code, and the Industrial Welfare Commission wage orders. That's a wide scope — covering wage claims, unemployment insurance determinations, and workers' compensation.

The core premise of AB5 is a presumption of employment. The hiring company has to actively disprove it by satisfying all three prongs of the ABC test. Get one wrong, and the worker is legally an employee — with all the obligations that come with that status.

How the ABC Test Works Under AB5 Law

AB5 applies the three-prong ABC test to determine contractor status. All three must be satisfied. There is no partial credit.

• Prong A: Freedom from Control. The worker must be free from the company's control and direction when performing the work, both under the contract and in practice. A contract that says the worker is independent isn't enough if your team is setting schedules, dictating methods, or managing day-to-day work.
• Prong B: Outside the Usual Course of Business. The work performed must fall outside the hiring company's usual course of business. A digital media company that hires a freelance writer to produce articles for its publication is, in the eyes of the law, asking someone to do what it does. This is the prong AB5 made famous and the one that drove much of the backlash from creative freelancers when the law passed. It's also why the professional services exemption — and its 35-piece submission limit for writers — matters so much for media companies specifically. Without it, most editorial freelancer engagements would fail Prong B on their face.
• ‍Note: California and Massachusetts are the only two states whose ABC test requires Prong B to be satisfied on a strict "usual course of business" basis. All other states using the ABC test allow an alternative — that the work is performed outside the company's usual places of business — which is considerably easier to satisfy. A contractor working remotely from their own office typically clears it automatically. This distinction matters for organizations managing contractors across multiple states.
• Prong C: Independently Established Business. The contractor must be customarily engaged in an independently established trade, occupation, or business of the same nature as the work being performed. This means the worker operates as an independent business with multiple clients, their own tools, and a market presence that would continue if your engagement ended. An LLC on paper doesn't satisfy this prong if the worker's entire livelihood depends on one company.

Who Is Exempt from AB5?

AB5 includes exemptions for a number of professions and arrangements. Exempt workers aren't subject to the ABC test — they're evaluated under the older Borello multi-factor test instead, which is considerably more flexible. An exemption doesn't automatically mean contractor status. It means the stricter ABC test doesn't apply.

Business-to-Business Contractors

If a contractor operates as a legitimate business entity (not an individual), performs services for another business, and meets 12 specific criteria, they may qualify for the B2B exemption. The criteria are detailed and must be met in practice — not just on paper.

Professional Services

A long list of professional occupations can qualify for exemption if specific conditions are met. These include:

• Lawyers, architects, engineers, and accountants
• Physicians, surgeons, dentists, and other licensed healthcare professionals
• Financial advisors and securities broker-dealers
• Certain marketing and human resources professionals
• Graphic designers, grant writers, fine artists, and certain other creative professionals
• Freelance writers, editors, and photographers (subject to separate qualifying conditions — see below)
• Translators, tutors, and certain travel agents

The Freelance Writer Submission Limit

One of AB5's most debated provisions applies to freelance writers and editors. They can qualify for the professional services exemption only if they submit fewer than 35 written pieces to a single hiring entity per year. Exceed that threshold and the exemption goes away, regardless of how independently they operate. This specific limit was introduced by AB2257, which modified AB5 in 2020. Photographers, illustrators, and other creative professionals have their own separate qualifying conditions under AB2257 — the 35-piece rule applies specifically to written content submissions and does not extend to those categories directly.

Referral Agencies

Businesses that connect clients with workers in certain categories (tutoring, cleaning, home repair, and others) can qualify for an exemption if they meet 10 specific requirements.

App-Based Drivers — Proposition 22

Rideshare and delivery drivers working for app-based platforms like Uber and Lyft were carved out by Proposition 22. Prop 22 allows these companies to classify their drivers as independent contractors rather than employees, provided they offer certain minimum earnings protections and benefits. This exemption applies strictly to app-based transportation and delivery workers.

2026 Updates — AB1514

Effective January 1, 2026, AB1514 extended the exemption for licensed manicurists through January 1, 2029, and for commercial fishers through January 1, 2031. It also clarified exemption conditions for certain creative and consulting roles. These extensions don't change the underlying requirements — they simply extend the timeline for qualifying professions.

What Are the Penalties for Misclassification Under AB5?

Short answer: significant. And they compound quickly.

‍

‍

"Per violation" is doing a lot of work in that table. Each misclassified worker can constitute a separate violation. If that worker was misclassified across multiple pay periods, each period can count separately. PAGA — the Private Attorneys General Act — adds another layer: it allows workers to sue on behalf of the state and collect 25% of penalties, assessed per employee per pay period. For a company that's been engaging 50 freelancers under incorrect classification for two years, the arithmetic gets uncomfortable fast.

Multiple California agencies enforce AB5:

• The Employment Development Department (EDD) handles unemployment insurance
• The Labor Commissioner handles wage claims
• The Franchise Tax Board handles state income tax

They don't coordinate their enforcement actions. That means a single misclassification situation can trigger inquiries from several directions at once.

What AB5 Means for Employers Operating in California

If your organization engages contractors who perform any work in California, here's what needs to be true of your program:

• The law applies to the work, not your company's location. A New York-based media company that hires a freelance writer in Los Angeles is subject to AB5 for that engagement. Where your headquarters is doesn't matter. Where the work happens does.
• Contracts don't override the law. An independent contractor agreement that says all the right things doesn't protect you if the working relationship looks like employment. California regulators look at the substance of the relationship, not the label.
• The exemptions are real but narrow. If you're engaging workers in a profession that qualifies for an exemption, that's useful — but only if the conditions are met in practice and documented clearly. An exemption that isn't supported by the actual working arrangement isn't an exemption.
• California's standard is stricter than most. If your program passes scrutiny in other ABC test states, don't assume that carries over. California and Massachusetts require satisfying Prong B on a "usual course of business" basis — a higher bar than the "usual places of business" alternative available elsewhere. Multi-state programs need to account for this explicitly.
• Classification needs to happen before work starts. Retroactive fixes are painful. You can update a contract after the fact, but you can't undo the classification exposure that accumulated during the engagement. The time to verify compliance is before the first deliverable.

What This Means for Your Contractor Program

AB5 is not a California problem. It's a classification infrastructure problem for any contingent workforce program — one that tends to surface at the worst possible time: when a contractor files for unemployment benefits, when the EDD opens an inquiry, or when a labor attorney starts asking questions about your engagement history.

The organizations that manage AB5 exposure well share a few operational characteristics. Classification decisions are made before work starts, not after. The working relationship reflects the contract — not just on paper, but in how work is actually assigned, managed, and delivered. Exempt status is documented against specific qualifying criteria, not assumed. And when material facts change — duration, scope, jurisdiction, role — classification gets revisited.

That's a workflow problem as much as a legal one. Most organizations don't have a structured process for running classification determinations at the point of engagement, tracking the conditions that make an exemption valid, or flagging when re-screening is needed. They rely on a contract template and hope the relationship stays clean.

Worksuite's AOR program runs structured, jurisdiction-specific classification questionnaires at onboarding — before a single deliverable changes hands. Under the AOR model, Worksuite is the contracting party with the independent contractor for covered engagements, which creates a meaningful structural separation between the working relationship and the employment relationship that classification tests are examining. Each determination is documented against the applicable legal test for that worker's location.

For covered engagements run through the platform using Worksuite's IC agreement templates, misclassification indemnification applies: if a classification recommendation turns out to be incorrect due to Worksuite's own error, Worksuite covers the resulting actual monetary losses — legal fees, court-ordered tax assessments, and regulatory penalties. That coverage is not blanket protection. It applies to covered engagements where program requirements are followed, and many conditions and exclusions govern what qualifies. But for organizations managing contractors across California and other jurisdictions, it represents a structural risk mitigation that most self-managed programs can't offer. See how it works in practice.

Classification done right isn't about finding the best argument that someone is a contractor. It's about understanding what the law actually requires for the engagement you're running — and building the documentation to support it.
