What EDD Audit Defense Covers
The California Employment Development Department (EDD) administers four state payroll taxes: Unemployment Insurance (UI), Employment Training Tax (ETT), State Disability Insurance (SDI), and California Personal Income Tax (PIT) withholding.
The EDD's audit authority is set out in California Unemployment Insurance Code (CUIC) §§ 1126–1128. EDD auditors examine employer payroll records, 1099 filings, contracts with workers, and job descriptions to determine whether the employer properly classified and withheld for its workforce.
The primary focus of EDD audits is worker classification. An employer that classifies workers as independent contractors and issues 1099s has no payroll tax obligation to withhold and remit for those workers. If the EDD concludes those workers were actually employees under California law, the employer owes all four payroll taxes on the reclassified workers' compensation — for every year in the audit period, plus interest and penalties.
This page covers EDD payroll tax audit defense. It also covers the federal side of payroll tax problems — particularly the Trust Fund Recovery Penalty under IRC § 6672, which is separately assessed by the IRS but often arises in the same fact pattern.
Worker Classification — California's ABC Test
California's worker classification standard is among the strictest in the country. Under AB 5 (effective January 1, 2020, codified at Labor Code §§ 2775–2787), a worker is presumed to be an employee unless the hiring entity proves all three prongs of the ABC test.
The three prongs:
(A) Control: The worker is free from the control and direction of the hiring entity in connection with the performance of the work, both under the contract and in fact.
(B) Outside the usual course of business: The worker performs work that is outside the usual course of the hiring entity's business.
(C) Independent enterprise: The worker is customarily engaged in an independently established trade, occupation, or business of the same nature as the work performed.
The B prong is the most consequential and the most commonly litigated. A plumber who provides plumbing services to a plumbing company fails it — because the work is inside the usual course of the company's business. A graphic designer who provides design services to a software company likely passes it — because design is outside the company's core business. The test is not about control or intent; it is about the economic reality of what the business does and what the worker does.
AB 5 exceptions exist for certain professions and arrangements: licensed professionals in specific fields, business-to-business contracting arrangements where both parties are genuine businesses, referral agencies meeting defined criteria, and others. These exceptions have been litigated extensively, and whether a specific arrangement qualifies requires a fact-specific analysis — not a checkbox review.
Federal Standard vs. California ABC Test
The IRS uses a different standard: the 20-factor common law test set out in Revenue Ruling 87-41, and IRS Form SS-8 for formal determinations. The federal test is generally more permissive than California's ABC test. A worker can be classified as an independent contractor under the federal standard while still being an employee under California law.
This gap creates a specific problem for businesses audited by both agencies: you may have had a defensible federal position under the IRS's 20-factor test, but that defense does not transfer to the EDD proceeding. The standards are independent.
Section 530 Relief — Federal Only
Under Section 530 of the Revenue Act of 1978, a business can avoid retroactive federal payroll tax reclassification if it can show it relied on a reasonable basis — published IRS guidance, a court decision, industry practice, or legal advice — for treating workers as independent contractors, and that it consistently treated the workers as contractors. This is a significant federal protection.
California does not have a direct Section 530 equivalent. A business that qualifies for Section 530 relief on the federal payroll tax side may still face full EDD liability on the state side.
The EDD Audit Process
An EDD audit follows a defined process from initial notice through assessment and appeal — and the audit period and penalty exposure depend heavily on what the EDD finds and how the employer responds.
The audit begins with an EDD audit notice mailed to the business. The notice identifies the audit period and may request an initial meeting. From there, the EDD auditor reviews payroll records, 1099 forms, contracts, job descriptions, and any other documentation relevant to the worker relationship. Initial document requests are broad — the scope tends to narrow as the EDD identifies the specific workers or arrangements at issue.
Standard audit period: three-year lookback under CUIC § 1132. The EDD typically examines the three most recent calendar years for which returns are available. If the EDD finds fraud or a failure to file, the lookback period extends to eight years.
After reviewing the records, the EDD auditor issues proposed findings. If workers are reclassified, the EDD calculates the UI, ETT, SDI, and PIT withholding that should have been remitted, assesses civil penalties under CUIC § 1128, and may assess additional penalties for willful failure under CUIC § 1128.1. Interest accrues from the date payment was originally due.
Notice of Assessment: After the audit findings are finalized, the EDD issues a Notice of Assessment. You have 30 days to appeal the assessment to the California Unemployment Insurance Appeals Board (CUIAB).
CUIAB hearing: The appeal is heard by an administrative law judge. The burden of proof is on the EDD to establish that an employment relationship existed — meaning the EDD must prove the three ABC test prongs were not satisfied for the workers it reclassified. The hearing is an adversarial proceeding; you present evidence, the EDD presents its case, and the ALJ rules.
If the CUIAB decision is unfavorable, the matter can be taken to Superior Court.
Trust Fund Recovery Penalty
The Trust Fund Recovery Penalty (TFRP) under IRC § 6672 is the federal government's mechanism for holding individuals personally liable for unpaid payroll taxes when a business has failed to remit them.
When a business withholds federal income tax and FICA (Social Security and Medicare) from employees' paychecks, those withheld amounts are held in trust for the federal government. They are not the employer's money. If the business uses those funds for something else — paying other creditors, covering operating costs, anything other than remitting to the IRS — the individuals responsible for that decision can be assessed the TFRP: 100% of the unpaid trust fund taxes, personally.
"Responsible person" is broadly defined. It includes owners, officers, CFOs, and in some cases bookkeepers or office managers who had authority to sign checks and directed payment decisions. The IRS has assessed the TFRP against individuals who were not technically officers but had functional control over which bills got paid. The critical question is not title — it is authority.
The TFRP follows the individual, not the business. A dissolved corporation, a bankrupt business, a company that no longer exists — none of these circumstances extinguish the TFRP against the responsible persons. The liability survives the entity.
Two defenses to the TFRP: First, challenging responsible person status — the individual did not have the authority the IRS attributes to them. Second, challenging willfulness — the failure to remit was not voluntary and intentional. Willfulness in the TFRP context does not require bad intent; it means the individual was aware of the obligation and made a conscious decision to pay other creditors instead. Courts have interpreted this broadly, and it is a difficult defense to establish once the IRS has evidence of continued business operations and selective creditor payments.
Form 4180 interview: When an IRS Revenue Officer is investigating TFRP liability, they typically request a Form 4180 interview — a structured interview to identify the responsible persons. These interviews are technically voluntary, but refusing them generally results in the Revenue Officer making a determination based on available documents, which is rarely favorable. If you receive a Form 4180 interview request, you should have representation before attending.
Industries Particularly Affected by EDD Reclassification
Worker classification issues concentrate in industries where the contractor model has been common practice, regardless of whether the law supports it.
Construction: Subcontractor relationships are standard in construction, and the EDD audits them heavily. The B prong of the ABC test is routinely at issue — a framing subcontractor working for a general contractor who performs framing may fail the B prong if the general contractor's business includes framing as part of its core services.
Technology and software: Software developers, QA engineers, and UX designers brought in as contractors for development projects are a common EDD audit target. The analysis depends on how closely the contractor's work overlaps with the company's core product work.
Healthcare: Per diem nursing, therapy staffing, and locum tenens physicians. Healthcare entities that staff clinical services through staffing agencies or direct 1099 arrangements face significant reclassification risk, particularly where the B prong cannot be satisfied because the clinical work is the business.
Real estate: Agent and broker relationships. Real estate professionals are subject to specific industry provisions under the California Labor Code, and the analysis is fact-intensive and exception-dependent.
Trucking and logistics: Owner-operator arrangements have been a specific litigation focus post-AB 5. The transportation industry has pursued and obtained some statutory carve-outs, but the landscape remains contested.
Gig economy businesses: The post-AB 5 landscape continues to evolve through litigation and ballot initiative. The current state of the law for gig platforms depends on the specific platform, the arrangement, and how California courts have addressed it.
A note on parallel audits: EDD and IRS share information under information-sharing agreements. An EDD audit finding that your contractors are employees often triggers an IRS payroll tax examination for the same period. Managing these in parallel — with consistent positions that work in both forums — is part of what representation looks like in these cases.
How Brotman Law Handles EDD Audits
We represent businesses and individuals at every stage of EDD audit proceedings — from the initial document response through CUIAB appeals — and we handle the parallel federal side when the IRS is involved.
On a typical EDD audit engagement, we start by reviewing the audit notice, identifying the workers and arrangements at issue, and assessing the exposure before responding to anything. The initial document response is consequential — what you produce and how you characterize the arrangements shapes the audit from there.
We run the ABC test analysis on the specific workers at issue. For arrangements that clearly fail the ABC test, the honest assessment is to determine whether settlement at the audit level is better than prolonged proceedings. For arrangements with a legitimate defense, we build the factual record to support it.
If the EDD issues a Notice of Assessment that is wrong — in whole or in part — we prepare the CUIAB appeal. CUIAB hearings are adversarial proceedings before an ALJ; we represent the business at the hearing and cross-examine the EDD's case.
For business owners or officers facing TFRP exposure, we handle the federal proceeding separately and concurrently. Contesting responsible person status or willfulness requires the right preparation and, where possible, protecting the Form 4180 interview from going in blind.
If you have received an EDD audit notice, or if the IRS is raising payroll tax issues, book a free 15-minute call. The situation usually becomes clearer quickly once we review the actual notice and the business's arrangement with the workers at issue.
Frequently Asked Questions
What triggers an EDD audit in California?
The most common triggers: a high ratio of 1099s to W-2s that signals a contractor-heavy workforce; an industry where worker misclassification is prevalent (construction, tech, healthcare, trucking); an employee complaint to the EDD or Labor Commissioner about misclassification; information matching that flags 1099 payments not accompanied by payroll tax filings; or a referral from the IRS following a federal payroll tax examination. The EDD also conducts industry-targeted audit campaigns.
What is the ABC test for worker classification?
Under California Labor Code §§ 2775–2787 (AB 5), a worker is presumed to be an employee unless the hiring entity proves: (A) the worker is free from the entity's control and direction in performing the work; (B) the worker performs work outside the usual course of the entity's business; and (C) the worker is customarily engaged in an independently established trade or occupation of the same type. All three prongs must be satisfied. The B prong is the most commonly dispositive — if the worker's services are central to the business's core operations, the arrangement almost certainly fails.
What happens if EDD determines my contractors are employees?
The EDD assesses all four payroll taxes that should have been withheld and remitted — UI, ETT, SDI, and PIT withholding — for every reclassified worker for the full audit period, which is typically three years under CUIC § 1132. Civil penalties under CUIC § 1128 are added, plus interest from when the payments were originally due. The finding often triggers a parallel IRS payroll tax examination for the same workers and period. If the business's officers had authority over payroll decisions and failed to remit withheld federal taxes, those individuals may face Trust Fund Recovery Penalty liability under IRC § 6672.
Can I appeal an EDD payroll tax assessment?
Yes. After the EDD issues a Notice of Assessment, you have 30 days to appeal to the California Unemployment Insurance Appeals Board (CUIAB). The CUIAB appeal is heard before an administrative law judge. The burden of proof at the CUIAB is on the EDD — the agency must establish that the workers were employees under the applicable standard. If the CUIAB decision is unfavorable, you can appeal to Superior Court. The 30-day appeal deadline is firm — missing it generally means the assessment becomes final.
What is the Trust Fund Recovery Penalty?
The Trust Fund Recovery Penalty (TFRP) under IRC § 6672 allows the IRS to assess 100% of unpaid federal payroll taxes personally against individuals who were "responsible persons" — those with authority to direct payment of the business's funds — and who willfully failed to remit employee withholdings to the IRS. The TFRP follows the individual regardless of what happens to the business: a dissolved, bankrupt, or closed business does not extinguish the TFRP against responsible persons. Willfulness does not require bad intent — it means awareness of the obligation and a conscious decision to pay other creditors instead.
