Here is what AB 5 enforcement actually looks like in practice. A California business owner receives an EDD audit notice. One former worker filed for unemployment after the relationship ended, and that single filing triggered the review. The auditor examines three years of payroll records and finds that several workers paid as 1099 independent contractors do not pass California’s ABC Test. The assessment comes back with back payroll taxes, interest, civil penalties, and unpaid wage premiums. The total exposure runs well into six figures. The owner, who personally guaranteed the company’s obligations, discovers that they can be held individually liable even though the business is organized as an LLC.
This is not a hypothetical. In 2026, the Employment Development Department intensified its enforcement of AB 5, leaving many California businesses facing massive assessments for what the state deems worker misclassification. It starts with a single filing. It ends with a bill most small businesses cannot absorb.
If your business currently pays workers on a 1099, this post is for you.
What Is California AB 5 and Why Does It Apply to Your Business?
Assembly Bill 5, enacted in January 2020, is California’s codification of a strict worker classification standard that applies to most businesses operating in the state. It governs how you may legally classify a worker as an independent contractor versus an employee under the California Labor Code, the Unemployment Insurance Code, and IWC Wage Orders.
The law did not emerge from thin air. It was the Legislature’s direct response to Dynamex Operations West, Inc. v. Superior Court (2018) 4 Cal.5th 903, a California Supreme Court ruling that adopted what is now called the ABC Test and applied it across wage order claims. AB 5 expanded that test to cover nearly all of California’s employment and labor law. Later that same year, AB 2257 added a substantial list of professional and business to business exemptions in response to significant industry pushback.
The practical result is this: unless your worker falls within a recognized exemption, California presumes they are your employee. The burden is on you, the hiring business, to prove otherwise. If you cannot satisfy all three prongs of the ABC Test, the worker is an employee under state law regardless of what your contract says, regardless of what your invoices say, and regardless of how long the arrangement has operated as though it were a contractor relationship.
What Is the ABC Test? Understanding All Three Prongs
To legally classify a worker as an independent contractor under AB 5, your business must satisfy every part of the following test. Failing even a single prong means the worker is an employee under California law.
Prong A: Freedom from Control.
The worker must be free from your control and direction in performing the work, both under the written contract and in actual practice. This means you cannot dictate the hours they work, the tools they use, the method they follow, or require them to attend your internal meetings, follow your dress code, or complete your training programs. The EDD looks at control as it actually operates in the relationship, not as it appears on paper. A contract that says “contractor” but describes an employee relationship is not a defense.
Prong B: Outside the Usual Course of Business.
The worker must perform services outside the usual course of your business. This is the prong that trips up the greatest number of California business owners. If the person is doing what your business fundamentally does, you are almost certainly failing this prong. A marketing agency that pays a 1099 copywriter to produce client deliverables, a construction company that pays a framer on a per-project basis, a staffing firm that places workers and pays them as contractors: in each of these situations, the contractor is performing work squarely inside the usual course of the business. They are not an outside vendor in any meaningful sense. They are an unclassified employee.
Prong C: Independently Established Trade or Business.
The worker must be customarily engaged in an independently established trade, occupation, or business of the same nature as the work performed. They must have other clients. They must hold themselves out to the public as a business. They must have their own business infrastructure, their own contracts, their own insurance. A worker who earns the majority of their income from your company, who has no other meaningful client relationships, and who does not operate as a genuine independent business will almost certainly fail this prong regardless of how the relationship is documented.
All three prongs must pass. There is no partial credit under California law.
What Are the AB 5 Exemptions and Why They Do Not Do What Most Owners Assume?
AB 5 and AB 2257 together created approximately 100 categories of workers and business relationships that are exempt from the ABC Test. Some of the more commonly recognized exemptions include licensed physicians and surgeons, licensed attorneys, licensed architects, licensed engineers, licensed accountants, real estate licensees, certain financial advisors, hairstylists and barbers who set their own rates and hours, and various professional service providers, including freelance writers, photographers, and graphic designers who meet specific enumerated criteria. There are also business-to-business exemptions that apply when a legitimately operating business entity contracts with another legitimately operating business entity, though those exemptions carry their own multi-factor conditions.
Here is the critical point that most business owners miss: an exemption does not automatically make your worker an independent contractor. Exempted occupations revert to the older, multifactor Borello test (S.G. Borello and Sons, Inc. v. Dept. of Industrial Relations, 1989). The Borello test is more flexible than the ABC Test, but it still requires a genuine analysis. The primary factor is the hiring entity’s right to control the manner and means of accomplishing the work, supplemented by considerations including whether the worker is engaged in an occupation distinct from the hiring entity’s regular business, the degree of permanence of the relationship, whether the work is integral to the hiring entity’s operations, and the worker’s opportunity for profit or loss.
Assuming that a licensed professional is automatically a contractor without running the Borello analysis is a mistake that has produced significant enforcement consequences for California businesses operating across every industry.
What Are the Most Common Misclassification Red Flags?
Before the EDD ever issues an audit notice, certain working arrangements signal elevated classification risk. Understanding these patterns is the first step toward managing your exposure.
You set or significantly influence their schedule. Telling a contractor when to start, when to take breaks, or when to remain available for your clients is control. Control indicates employment under California law.
You require training. Onboarding a contractor to your internal systems, processes, or customer service standards goes directly to the control analysis. Employees receive training. Independent contractors already possess the skill and apply it as they see fit.
They use your equipment or work primarily at your location. A contractor who works on your computers, drives your vehicle, or operates predominantly out of your office is not running an independent business. They are functionally an employee.
They work exclusively or predominantly for your company. If the vast majority of a worker’s income comes from your business over multiple years, they are not an independently established business in any practical sense. Prong C of the ABC Test fails on these facts.
They perform the same work as your employees. This is the Prong B problem in its clearest form. If you have salaried employees performing Task X and 1099 contractors also performing Task X, the contractors almost certainly fail the ABC Test; Task X is plainly within your usual course of business.
Your contract says “independent contractor,” but the relationship operates like employment. The written label carries no legal weight if the actual working relationship contradicts it. The EDD examines conduct and economic reality, not documentation alone.
What Happens During an EDD Audit?
EDD auditors typically review the prior three years of payroll tax records, though this period may be extended when returns were not filed or when the auditor identifies evidence of concealment. Most audits begin with one of two triggers: a former contractor files for unemployment insurance benefits to which independent contractors are not entitled, or a current or former worker files a wage complaint with the Labor Commissioner.
The EDD will issue one of four determinations after completing its review: no change, overpayment resulting in a credit, underpayment resulting in an assessment, or some combination of both. During the process, auditors will interview your workers about the actual nature of the working relationship. Their answers carry significant weight regardless of what your contracts say.
What makes California EDD audits particularly dangerous for small businesses is cross-agency coordination. The EDD and the IRS operate under an information-sharing agreement. A state payroll tax misclassification finding can be shared with the IRS, converting a California compliance problem into a federal one. Business owners who are already managing the state assessment then face a parallel federal inquiry covering the same workforce and the same time period.
Additionally, under California Unemployment Insurance Code Section 1735, any officer, major shareholder, or other person who had charge of the business affairs and willfully failed to pay the required taxes can be held personally liable for unpaid payroll taxes, interest, and penalties. The state can pursue your personal bank accounts, your personal assets, and your home, even if the business entity has since been dissolved.
What Does a Misclassification Finding Actually Cost?
The financial exposure from an AB 5 misclassification finding is layered, and each layer compounds the others.
Back payroll taxes. You owe the employer’s share of Unemployment Insurance, Employment Training Tax, State Disability Insurance, and California Personal Income Tax withholding for every reclassified worker over the entire audit period. These taxes can total 10 to 15 percent of all compensation paid to reclassified workers.
Interest. Interest accrues from the original due dates, compounding backward over three or more years.
Unpaid wage and hour claims. Reclassified workers may pursue private claims for unpaid overtime, missed meal and rest break premiums, and unreimbursed business expenses under Labor Code Section 2802. These claims reach back four years and include attorneys’ fees, which in California often equal or exceed the underlying damages.
Civil penalties for willful misclassification. Under Labor Code Section 226.8, California’s Labor and Workforce Development Agency has the authority to assess civil penalties of between $5,000 and $15,000 per violation where misclassification was willful; the penalty rises to between $10,000 and $25,000 per violation where the agency finds a pattern or practice. Willful means voluntarily and knowingly misclassifying, which courts have found to include situations where an owner received prior notice of classification concerns and did not act on them.
PAGA exposure. The Private Attorneys General Act allows misclassified workers to file suit on behalf of themselves and other aggrieved employees, aggregating penalties across an entire contractor workforce. PAGA exposure is a separate category of liability that often exceeds the underlying wage claim.
When you run these numbers across even a modest contractor workforce, five to ten workers over three years in a mid-sized San Diego business, the total exposure moves quickly into six figures. For businesses with larger contractor populations, the assessment can be existential.
How to Audit Your Own Classification Before the State Does It for You
The most effective thing a California small business owner can do right now is conduct a proactive classification review before receiving any government notice. A voluntary review, done correctly and documented properly, positions you far better than a forced reclassification under audit.
Start by listing every person your business has paid on a 1099 in the last three years. Include all contractors, freelancers, project-based workers, and gig relationships regardless of the dollar amount involved.
Apply the ABC Test honestly to each relationship. Focus first on Prong B: Is the work this person performs within the usual course of your business? If you cannot confidently answer no, you have a classification issue that deserves attention.
Check whether a recognized exemption applies to the worker’s occupation or to your business relationship. If an exemption does apply, identify it specifically, confirm that all conditions of that exemption are met, and then apply the Borello factors as a secondary analysis.
Review your written contracts. A contract that describes employee-level control, set hours, required training, exclusive work arrangements, and use of your equipment serves as evidence against you in an audit, not in your favor.
Document the objective indicators of genuine contractor status where they exist: the worker’s other clients, their own business entity, their business license, their own professional liability insurance, and their control over the manner and means of their own work.
Where reclassification is warranted, do it proactively. A business that identifies and corrects a misclassification before a complaint is filed has substantially more leverage than one that is forced to reclassify under a government audit with penalties already accruing.
When Does an Attorney-Led Classification Audit Make Sense?
For businesses with more than a handful of contractors, or any business in a higher-risk industry such as construction, technology, healthcare services, creative agencies, logistics, or staffing, a professional classification audit is a sound investment for a straightforward reason: an attorney-conducted audit applies legal privilege to the entire analysis. This means the findings are protected from disclosure in subsequent litigation or government proceedings. A self-audit does not carry that protection. If you document a problem internally and then get audited, the EDD can subpoena your own records and use your own analysis against you.
An attorney can also help you structure contractor relationships going forward in a way that maximizes legal defensibility: proper written agreements, properly documented Borello or ABC factors, legitimate business-to-business structures where the exemptions genuinely apply. And if an audit does occur, you have counsel who already understands your workforce structure and can respond from day one with a complete factual record.
The cost of a proactive classification audit is a fraction of what a single EDD assessment, let alone a PAGA action, would cost your business. The businesses that avoid six-figure penalties are the ones that address this before a disgruntled worker files a claim, not after one already has.
What San Diego Small Business Owners Should Do Right Now
AB 5 is not a technicality buried in the California Labor Code. It is the primary legal framework governing every contractor relationship your California business operates, and enforcement is intensifying as the EDD expands audit activity across industries in 2026. State agencies have increased data sharing with the FTB and the IRS, meaning a single misclassification finding can trigger cascading liability across multiple jurisdictions simultaneously.
If you are currently paying workers on a 1099 and have not had a legal review of those classifications, the question is not whether you have exposure. The question is how much.
