Watch: serious payroll return errors in an EDD audit

We have handled EDD payroll tax audits and worker reclassification proceedings as a California tax attorney since 2013. The EDD’s assessment process moves quickly, and the window to contest a finding, or to shape the record before the auditor finalizes it, closes faster than most business owners expect. If you have received an EDD audit notice or a worker reclassification questionnaire, what you provide in the initial stages of the exam matters a great deal.

This page explains what EDD audits cover, how the ABC test under AB5 works, what happens during the audit itself, and what your options are if the EDD issues an assessment. It also covers the CUIAB appeals process and how we approach the defense at each stage.

What EDD Audits Cover

The EDD administers four distinct payroll taxes, and an audit examines compliance with all of them for every worker relationship in scope. Understanding which taxes are at issue, and how they are assessed, is the starting point for any EDD audit defense.

The four taxes the EDD administers are:

  • Unemployment Insurance (UI): An employer-only contribution. The EDD determines whether each worker is covered under California’s UI program, and whether the employer correctly reported and remitted UI contributions. Misclassified independent contractors are excluded from UI coverage, which is one of the EDD’s primary audit concerns.
  • State Disability Insurance (SDI): An employee-paid tax that the employer withholds and remits. When a worker is reclassified as an employee, the employer is generally assessed for the SDI that should have been withheld, even if the employer did not actually withhold it from the worker’s pay.
  • Employment Training Tax (ETT): A small employer-only contribution that funds the state’s workforce training programs. ETT is assessed on the same wage base as UI.
  • Personal Income Tax (PIT) Withholding: California requires employers to withhold state income tax from employee wages and remit it to the EDD. When workers are reclassified as employees, the employer is assessed for the PIT withholding that should have been remitted.

EDD audits are triggered several ways. Common triggers include 1099s filed for workers whose counts are inconsistent with the employer’s reported payroll, anonymous tips from workers or competitors, industry average comparisons (the EDD maintains average employee-to-revenue ratios by industry code), prior audit history, and data matching against IRS Form 940 and Form 941 filings. Federal payroll tax returns and California EDD filings often tell different stories, and the EDD uses that inconsistency to identify examination candidates.

The EDD’s standard look-back period is three years from the later of the date the return was due or the date it was filed. For fraud or failure to file, the limitations period is open-ended. There is no cap on how far back the EDD can assess. In practice, that means a worker reclassification finding for a business that has been misclassifying workers for several years can produce an assessment covering four or more tax years across every reclassified worker.

EDD Audit vs. EDD Appeal

An EDD audit is the examination phase. It ends with a Notice of Assessment. The appeal, filed with the California Unemployment Insurance Appeals Board, is a separate proceeding that begins after the assessment is issued. The two phases require different strategies, and the record built during the audit affects the appeal.

What the EDD collects, and how a benefit audit differs from a payroll tax audit

The EDD collects California’s four payroll taxes, and it runs two different kinds of audit that are easy to confuse. It collects unemployment insurance and the employment training tax, which the employer pays on the first $7,000 of each employee’s wages, and state disability insurance and personal income tax withholding, which are withheld from the employee’s pay. Employers report wages each quarter on the DE 9 and DE 9C, deposit the tax on the DE 88 schedule, and report independent contractors paid $600 or more on the DE 542. That last return is an audit lead, because a business filing many DE 542s and few W-2s looks like one with employees it is not reporting.

A benefit audit is not a payroll tax audit. When a former worker claims unemployment benefits, the EDD sends the employer a benefit audit form asking whether that person earned wages during the weeks claimed. It is a form to complete accurately and return, aimed at the claimant rather than at your classification of anyone, and it does not need a lawyer. A payroll tax audit starts with an Inquiry Regarding Records, covers every worker for a three-year period, and ends in a Notice of Assessment. The rest of this page is about the second kind.

Worker Classification: The AB5 ABC Test

Under California AB5 (Labor Code § 2775), a worker is presumed to be an employee, and the hiring entity must affirmatively prove all three prongs of the ABC test to establish independent contractor status. The presumption favors employee status. The burden is on the employer.

The three prongs of the ABC test are:

  • Prong A: 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 actual practice.
  • Prong B: The worker performs work that is outside the usual course of the hiring entity’s business.
  • Prong C: The worker is customarily engaged in an independently established trade, occupation, or business of the same nature as the work performed.

Prong B is the provision that reclassifies the most workers. The question is whether the worker does what the business does. A marketing firm that retains a freelance copywriter to write marketing copy is retaining someone who does exactly what the business does, Prong B fails, and the copywriter is an employee under the ABC test. The contract, the invoicing arrangement, and the labels the parties used are irrelevant once Prong B fails. The EDD does not negotiate around Prong B.

AB2257, which California enacted in 2020, added a list of statutory exemptions covering certain professional relationships, lawyers, doctors, accountants, architects, engineers, insurance agents, direct sales representatives, and others. These exemptions are narrow and specific. They do not cover most business service relationships. For exempt categories, the pre-AB5 Borello multi-factor test (S.G. Borello & Sons, Inc. v. Dept. of Industrial Relations, 48 Cal. 3d 341 (1989)) applies, which is a different analysis, not a blanket independent contractor classification.

One distinction that comes up often in EDD audit defense: IRC § 530, the federal safe harbor that protects businesses from federal employment tax liability when there was a reasonable basis for treating a worker as an independent contractor, does not apply to California EDD taxes. A business that qualifies for the § 530 federal safe harbor can still face a full California EDD assessment for the same workers in the same periods. Federal and California classification rules operate independently of each other.

The math on multi-year reclassification gets significant quickly. A business with ten workers misclassified as independent contractors over four years, each earning $80,000 annually, is looking at a potential assessment base of $3.2 million in wages, before the EDD applies the tax rates, penalties, and interest. That is how EDD reclassification assessments reach seven figures.

What Happens During an EDD Audit

An EDD field audit typically begins with an opening conference, proceeds through a document production phase, and ends with a findings letter that becomes a Notice of Assessment if the auditor concludes a deficiency exists. Each phase presents opportunities to narrow the EDD’s analysis, or to lock in positions that are difficult to walk back later.

The opening conference is where the EDD auditor explains the scope of the examination and provides an initial list of document requests. The records the EDD typically requests include payroll records, worker agreements (both written contracts and any oral arrangements the employer can describe), 1099s and corresponding invoices, client contracts that describe the duties and work product of the workers in question, and bank records to trace payments. The auditor is looking for evidence of control, who set the schedule, who provided tools and equipment, who determined the work methods.

We appear at the opening conference on behalf of our clients. The opening conference is not a formality. The positions the employer takes at the opening conference, and what the employer agrees to produce, shape the entire examination. Producing records without reviewing them for privilege issues, or making representations about worker relationships without understanding how the EDD will evaluate them, can create problems that are difficult to fix.

During the audit, the EDD auditor may also interview workers directly, particularly workers whose classification is at issue. Workers who have been reclassified as employees by the EDD in a prior proceeding, or who filed unemployment claims, are obvious candidates for interviews. Managing the information flow between the auditor and the workers is part of the audit defense.

The EDD’s findings letter sets out the auditor’s proposed assessment, including the workers it is reclassifying, the tax periods covered, the wage base used for each worker, and the resulting tax, penalty, and interest calculations. The findings letter is not the final assessment. There is typically an opportunity to respond and contest the findings before the Notice of Assessment is issued. That response window is critical and should not be waived.

The EDD notices, by name

An EDD audit produces a predictable sequence of documents, and the one with a deadline is the Notice of Assessment.

  • Inquiry Regarding Records (DE 996): the opening letter. It names the audit period, asks for records, and comes with a Pre-audit Questionnaire (DE 996Q) and Information Sheet DE 231TA, the EDD’s own description of the process. The questionnaire also asks about the business, so answer it with counsel, because it is the auditor’s first piece of evidence.
  • The DE 231 series: the information sheets the auditor cites for the EDD’s positions, starting with DE 231 (Employment), on who is an employee. They are the EDD’s reading of the law, not the law itself.
  • DE 1870 (Determination of Employment Work Status): the form a business or a worker can file to ask the EDD to rule on one worker’s status. Filing it during an audit rarely helps, because the answer comes from the auditing agency.
  • Proposed Notice of Assessment (DE 6517P): the auditor’s findings before they are billed: the workers reclassified, the periods, the wage base and the tax. This is the stage to contest the findings with the auditor and the audit supervisor, and a pre-assessment conference can be requested.
  • Notice of Assessment: the bill. Under Unemployment Insurance Code section 1222 you have 30 days from service to file a petition for reassessment with the California Unemployment Insurance Appeals Board, and an administrative law judge can grant one additional 30 days for good cause. Without a timely petition the assessment is final and moves to collection.
  • Statement of Account: the EDD’s running balance by quarter once the assessment is final. It is a collection document rather than an appeal document, and the figure the EDD’s collectors work from.

The petition goes to the CUIAB, which is independent of the EDD. An administrative law judge hears the case fresh, either side can appeal to the Appeals Board itself, and after that the only review is a writ of mandate in superior court. The guide to California payroll tax audits covers each step.

The EDD letters, one page each

Most payroll tax audits arrive as a specific letter. Each page below explains one of them in plain English: what it means, the deadline it carries, what the EDD can do next, and how we handle it.

EDD Assessment: Penalties and Exposure

An EDD assessment for worker misclassification includes back payroll taxes plus a standard penalty structure, and in cases involving fraud or responsible-party liability, the exposure extends beyond the business entity itself.

The standard penalty structure for an EDD assessment includes:

  • Failure to withhold PIT: 10% of the tax owed on wages that should have been withheld.
  • Failure to pay employer contributions (UI/ETT): 10% of the contributions owed, plus interest at 7% per annum (simple interest, not compounded).
  • Fraud penalty: 25% of the additional assessment if the EDD determines that the underpayment was due to fraud or intentional disregard of the law.

Personal liability is a real exposure in EDD matters. Under California Unemployment Insurance Code § 1735, the EDD can assess responsible parties, corporate officers, owners, or others with control over payroll decisions, personally for the company’s unpaid taxes. This assessment can follow the individual even if the business entity dissolves or files for bankruptcy. The responsible-party assessment is one reason EDD matters deserve careful attention from the outset, not just when the business is facing financial difficulty.

Worker reclassification also creates downstream exposure that the EDD assessment itself does not capture. A reclassified worker is now an employee under California law, which means the California Labor Commissioner (DLSE) can pursue back wage claims, overtime, and benefit contributions for the same workers and the same periods. A DLSE proceeding is separate from the EDD audit, but the facts overlap substantially. A reclassification finding by the EDD creates a factual record that the DLSE can use.

As payroll tax attorneys, we evaluate the full exposure picture, EDD taxes, penalties, and responsible-party risk, before recommending a resolution approach. The calculation matters for deciding whether to contest, settle, or pay and abate.

Appealing an EDD Assessment

You have 30 days from the date of the Notice of Assessment to file a written appeal with the California Unemployment Insurance Appeals Board (CUIAB), and that deadline is jurisdictional. Missing it eliminates your right to an administrative appeal.

A CUIAB appeal goes to an administrative law judge who conducts a de novo review of the EDD’s assessment. De novo means the ALJ is not deferring to the EDD’s finding, the entire question of whether the workers were correctly classified is open again on the evidentiary record you build at the hearing. That is a meaningful distinction. The CUIAB hearing is not a rubber stamp on what the EDD auditor concluded.

CUIAB hearings are typically set three to six months after the appeal is filed. The hearing is a formal administrative proceeding, witnesses testify, documents are introduced into evidence, and both the EDD and the appellant have the opportunity to present their case. We prepare for CUIAB hearings the same way we prepare for a bench trial: theory of the case, witness preparation, documentary record, and a clear presentation of why the EDD’s classification analysis was wrong under Labor Code § 2775 and the ABC test.

If the CUIAB upholds the assessment, the next available forum is California Superior Court through a petition for writ of mandate. The Superior Court review is deferential to the CUIAB’s factual findings, so the record built at the CUIAB level matters. Appeals to Superior Court add 12 to 24 months to the timeline.

The appeal process also creates a formal negotiating posture. The EDD does settle, particularly where the classification analysis is legally ambiguous, where Prong B is genuinely disputed, or where the business can demonstrate that it had a reasonable basis for its classification at the time. Settlement discussions often happen in parallel with the CUIAB proceeding. We handle both tracks simultaneously.

For matters where federal payroll tax is simultaneously at issue, which is common when the IRS is also questioning worker classification under Form 941 or conducting a federal employment tax audit, we coordinate the California EDD defense with the federal response. As IRS attorneys, we handle both proceedings. Federal and state classification determinations are independent of each other, but the underlying factual record overlaps, and consistency in the positions taken matters.
