What California State Employers Should Expect
California employers who pay workers in cash, issue Forms 1099 to workers who function like employees, underreport wages, fail to register with the Employment Development Department, or omit payroll tax deposits can attract EDD underground economy scrutiny. The risk is especially high in industries where cash labor, subcontractor crews, family labor, day laborers, tipped workers, undocumented workers, or jobsite labor are common. What may begin as a payroll tax audit can expand into a multi-agency investigation involving EDD, the Franchise Tax Board, the California Department of Tax and Fee Administration, the Department of Industrial Relations, the Contractors State License Board, the Department of Insurance, Department of Labor, or even the IRS.
The term “underground economy” does not refer only to businesses with no public presence. A licensed restaurant, contractor, smoke shop, warehouse, car wash, janitorial company, medical practice, trucking business, or retail store can become part of an underground economy investigation if California believes the business used cash or other methods to conceal payroll, workers, tax liability, licensing violations, or insurance exposure. For employers, the danger is not limited to back payroll taxes. EDD findings can lead to payroll tax assessments, worker classification disputes, civil fraud penalties, workers’ compensation and labor law exposure, income tax issues, and potential criminal tax exposure where the facts show intent to evade.
What EDD Means by the Underground Economy
EDD’s Underground Economy Operations program focuses on employers that avoid payroll tax, labor, licensing, and related legal obligations. Common red flags include unreported cash wages, workers paid under the table, wages reported on Forms 1099 even though the workers may be employees, unreported or unpaid payroll tax deductions, unregistered employer activity, missing wage reports, and payments to workers that do not match the employer’s filed payroll tax returns. Retailers, contractors, restaurants, and service businesses in cash-intensive industries can face heightened audit risk under this program.
California’s Joint Enforcement Strike Force and related enforcement teams exist because underground economy cases often involve more than one agency. EDD may focus on payroll taxes and worker classification, while DIR may examine wage-and-hour issues, CSLB may examine contractor licensing, CDI may examine workers’ compensation insurance, CDTFA may examine sales and use tax, and FTB may examine income tax. Therefore, an employer should not assume that an EDD inquiry is isolated. Information developed during an EDD audit can create collateral risk with other agencies, a dynamic that the Joint Enforcement Strike Force is specifically designed to exploit.
This is especially important because EDD audits can involve both the employer’s records and worker interviews. If the employer’s payroll reports say there were no employees, but jobsite interviews, bank records, cash logs, invoices, or worker statements show people performing services, the case can shift quickly from ordinary payroll compliance to suspected concealment.
What Happens During an EDD Employment Tax Audit
An EDD employment tax audit generally begins with an inquiry regarding records and an entrance interview. The auditor explains the purpose of the audit, gathers information about the business, and reviews the employer’s accounting and payroll records. EDD audits generally cover a three-year statutory period consisting of the 12 most recently completed calendar quarters, beginning with a test year, but the examination can expand to the full audit period and, in some circumstances, beyond that period.
EDD may review the business’s ownership and entity type, payroll records, check registers, canceled checks, bank statements, general ledger, cash payment records, financial statements, federal and state income tax returns, Forms 1099, federal employment tax returns, and California DE 9 and DE 9C filings, wage reports, employee earnings records, and written agreements. If worker classification is in dispute, EDD may also examine invoices, billings, corporate minutes, contracts, and other documents showing how the relationship actually worked.
The audit’s central questions are usually straightforward: Who performed services? Were they employees or independent contractors? Were all wages reported? Were UI, ETT, SDI, and PIT withholding correctly handled? Were cash payments included? Were Forms 1099 used to avoid payroll tax? Did the business properly register as an employer? Did the employer withhold amounts from workers but fail to remit them? The answers determine whether the employer faces no change, a refund, an assessment, or a much more serious fraud-sensitive dispute.
Worker Classification, Cash Pay, and Missing Payroll Records
Worker classification is often the heart of an EDD underground economy audit. California generally presumes workers are employees unless the applicable legal test supports independent-contractor treatment. In many cases, the ABC test applies, though statutory exceptions may require the Borello multifactor test instead. Employers that rely solely on Forms 1099 are exposed, because the label on the form does not determine the worker’s legal status. Where willful misclassification is found, Labor Code Section 226.8 can impose separate civil penalties of $5,000 to $15,000 for each violation, and $10,000 to $25,000 for each violation if there is a pattern or practice of willful misclassification, in addition to other available penalties.
Cash pay creates a separate and often more dangerous problem. Wages are compensation for personal services, whether paid by check, cash, electronic debit, payment apps, or noncash benefits. If a business pays cash wages but does not report them, EDD may assess unpaid UI, ETT, SDI, and PIT withholding exposure. If the employer withheld SDI or PIT from employees but failed to remit those amounts to EDD, the issue becomes more serious because the employer was holding amounts deducted from employees’ wages. Bank records, cash withdrawals, payment records, worker interviews, and other source documents can expose the gap between what the employer reported and what the records actually show.
Missing records rarely help the employer. EDD requires employers to keep true and accurate payroll records showing workers and payments. If records are incomplete, EDD may reconstruct payroll from bank withdrawals, cash payments, check registers, Forms 1099, worker interviews, jobsite records, contractor invoices, POS data, appointment logs, sales records, or other available evidence. An employer who paid workers off the books should not assume the state cannot prove the payments, and an employer who destroys or alters records to conceal that evidence has crossed from a civil compliance issue into obstruction territory.
When EDD Audit Problems Become Criminal Tax Exposure
Not every EDD audit is criminal. Employers make mistakes, misunderstand worker classification, use poor payroll systems, or rely on bad advice. Those cases may still create assessments, penalties, and interest, but they are not automatically criminal. The risk changes where the facts show intentional concealment, false payroll returns, cash wages hidden from payroll records, Forms 1099 issued to disguise employee wages, workers paid from personal accounts, false statements to EDD, altered records, or withheld payroll taxes not paid over to the state. Those facts can push a case from civil compliance into eggshell or reverse eggshell audit territory, where every statement the employer makes during the audit can become evidence in a criminal proceeding.
California law can impose serious consequences for a person who willfully fails to file required returns or reports with the intent to evade payroll tax, or who willfully makes false or fraudulent payroll tax reports or statements with like intent. California law also separately criminalizes willful failure by a person required to collect, account for, and pay over withheld amounts to collect or truthfully account for and pay over those amounts. Beyond criminal tax exposure, CUIC Section 1735 can impose personal liability for the unpaid contributions, withholdings, penalties, and interest on any officer, major stockholder, or other person having charge of the affairs of a corporation, association, registered limited liability partnership, foreign limited liability partnership, or LLC who willfully failed to pay required employment taxes or withholdings when they became delinquent. That personal liability can reach individuals with sufficient charge over the entity’s affairs even when the business entity itself cannot or does not pay the liability. In addition, EDD’s civil fraud or intent-to-evade penalty under CUIC Section 1128(a) can add 50 percent of assessed contributions, with an additional 50 percent penalty under CUIC Section 1128(b) in cases involving failure to provide required information returns to workers.
If the same facts show off-book payroll, withheld federal payroll taxes not paid to the IRS, false Forms 941, cash payroll, nominee accounts, or false income tax returns, the employer may face IRS employment tax exposure or a criminal tax investigation by IRS Criminal Investigation Division (CID). IRS-CI reported an 89 percent conviction rate in fiscal year 2025, with 2,043 prosecution referrals and 1,611 convictions. EDD audit information may be shared with the IRS under an exchange agreement, meaning a state payroll audit can become the starting point for a federal criminal tax inquiry.

Contact the Tax Law Offices of David W. Klasing if EDD Is Auditing Your Business
At the Tax Law Offices of David W. Klasing, our dual-licensed Civil and Criminal Tax Attorneys and CPAs represent California employers facing EDD underground economy audits, worker-classification disputes, cash payroll issues, missing wage reports, unfiled payroll tax returns, unpaid SDI and PIT withholding, Forms 1099 reclassification, and multi-agency exposure involving EDD, FTB, CDTFA, DIR, CSLB, CDI, and the IRS. We understand that some EDD issues are civil payroll tax problems, but we also understand when the facts may suggest intentional concealment, fraud, or criminal tax exposure.
We aim to determine whether the employer’s exposure is civil, eggshell, reverse eggshell, or potentially criminal before the business makes the next move. At the Tax Law Offices of David W. Klasing, we analyze payroll records, bank accounts, check registers, Forms 1099, DE 9 and DE 9C filings, federal Forms 941 and 940, worker contracts, jobsite records, cash payment logs, income tax returns, sales tax filings, workers’ compensation records, and communications with payroll providers or workers through both a civil and criminal tax defense lens. Where the facts support a civil explanation, we work to preserve credibility and correct the record. Where the facts are potentially criminal, our focus shifts immediately to damage control, a privilege-sensitive investigation, and, where possible, preventing the matter from progressing to criminal tax prosecution.
If EDD is asking about cash wages, unreported workers, independent contractors, unpaid payroll taxes, missing wage reports, or workers paid outside the payroll system, do not alter records, coach workers, file rushed corrections, or try to explain the issue casually before counsel understands the facts. We are happy to provide a reduced-rate initial consultation, which you can arrange by calling the Tax Law Offices of David W. Klasing at (800) 681-1295 or by clicking HERE to schedule online. EDD underground economy audits can begin as payroll disputes, but where intent, cash wages, and false records are involved, they must be handled as potential criminal tax exposure from the start.
