The Employment Development Department (EDD) has stepped up enforcement in California, and the most common trigger for an audit is worker misclassification. What often surprises businesses is that these problems frequently trace back to how their accounting firms handled classification, documentation, and payroll compliance. Firms serving clients in high-volume gig, logistics, delivery, or rideshare sectors are the most exposed, because those industries depend heavily on independent contractors and small oversights can lead to audits with significant costs.
Why EDD Audits Begin
EDD audits rarely come out of nowhere. They start with identifiable triggers: mistakes in classification, lapses in payroll processes, or discrepancies that raise questions. Accounting firms that recognize and address these early warning signs can reduce the impact, and sometimes avoid an audit altogether.
Misclassification Triggers Most Audits
Misclassification is the term for treating a worker as an independent contractor when they should be treated as an employee. A single unemployment insurance claim by a 1099 worker can be enough to open an audit, after which the agency reviews that employer’s records across multiple years. Once an audit begins, auditors examine payroll filings, 1099 issuance, and worker agreements. For background on where the line falls, see our note on contractor versus employee designation or the state’s Employment Status Portal.
Late or Missing Payroll Tax Filings
Consistently late payroll tax returns, or delayed payment of taxes, is a clear signal to EDD. Even minor delays can attract attention, and repeated delinquency increases the likelihood of an audit. EDD imposes penalties for late payments that can escalate quickly, so timely filing matters more than it might appear.
Discrepancies Between Reported Wages and Tax Remittances
EDD routinely cross-references data with other agencies, including the Internal Revenue Service and the Workers’ Compensation Insurance Rating Bureau. Inconsistencies between the wages and taxes reported to EDD and those reported elsewhere can trigger a crossmatch audit, and internal discrepancies within a business’s own EDD filings can do the same.
Incomplete or conflicting records produce verification queries of their own. Even where these are peripheral to classification, they can broaden the scope of an audit and increase the pressure on the business and its advisors.
The ABC Test and Presumed Employee Status
California applies the ABC Test to most classification questions. A worker is presumed to be an employee unless the hiring entity can establish all three of the following:
- 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.
- The worker performs work that is outside the usual course of the hiring entity’s business.
- The worker is customarily engaged in an independently established trade, occupation, or business of the same nature as the work performed.
Failing any one of these prongs places the worker in employee status. That makes careful review essential for any client using contractors, particularly where the contractor’s duties overlap with the client’s core business operations.
High-Risk Industries
Certain sectors receive closer attention because they rely heavily on flexible or gig-style labor, including delivery and logistics, rideshare, construction trades, janitorial services, and staffing. Firms with clients in these sectors should expect classification decisions to be examined more closely. Our note on working with contractors and audit risk covers this in more detail.
What an Audit Can Cost
The consequences of an EDD audit that uncovers misclassification are rarely limited to a single penalty. Audits can expose clients to layered liabilities, reputational damage, and constraints on how they operate afterwards.
Back Taxes and Multi-Year Exposure
Once EDD concludes that a worker was misclassified, it can assess back taxes over several years. This includes unpaid Unemployment Insurance, State Disability Insurance, and Employment Training Tax contributions, along with any personal income tax withholding that should have been made. Totals accumulate quickly where multiple workers are involved or the look-back period is long.
Civil Penalties for Willful Misclassification
Under California Labor Code section 226.8, deliberate misclassification carries civil penalties:
- $5,000 to $15,000 per misclassified worker for a single violation.
- $10,000 to $25,000 per worker where the employer has engaged in a pattern or practice of willful misclassification.
These penalties sit on top of any assessed taxes, interest, or other charges. Employers found to have intentionally misclassified workers must also publicly post notice of the violation and the corrective action taken.
Late Payment Penalties and Interest
Late deposits attract a penalty calculated by how late the payment is: 2% for deposits up to five days late, 5% for deposits between six and fifteen days late, and 10% for deposits sixteen or more days late.
Separate penalties apply to fraudulent filings and to misclassification, over and above unpaid payroll taxes. Where EDD treats misclassification as a pattern or practice, exposure increases substantially.
Liability can also reach individuals. Under CUIC section 1735, EDD may assess an officer, major stockholder or other person in charge of a business’s affairs personally, where that person was responsible for paying the taxes and willfully failed to do so. Both elements are needed: control over the finances, and a deliberate decision not to remit. An inability to pay is not the same as willfulness. Where a section 1735 assessment is made it covers the full amount, including penalties and interest, and it is not dischargeable in bankruptcy. EDD can then levy personal accounts, lien personal property and garnish wages. Where payroll tax fraud is pursued as criminal conduct, it can carry a custodial sentence.
Interest accrues daily and compounds on all unpaid tax and associated penalties. Rates are adjusted twice yearly, so check the current figure against EDD before relying on it:
| Overdue date | Interest rate | Daily interest factor |
|---|---|---|
| 01/01/25 to 06/30/25 | 8% | 0.000219 |
| 07/01/25 to 12/31/25 | 7% | 0.000192 |
| 01/01/26 to 06/30/26 | 7% | 0.000192 |
Private Litigation and PAGA Exposure
Beyond the administrative penalties, clients face private exposure. Misclassified workers can bring claims for unpaid overtime, meal and rest break violations, unreimbursed business expenses, and related wage-and-hour matters. Under the Private Attorneys General Act, those claims can multiply liability considerably, in some cases well beyond the original audit assessment.
What Accounting Firms Can Do
Accounting firms are usually the first line of defense for their clients. Acting before an audit notice arrives costs a good deal less than responding after one does.
Conduct a Self-Audit Using the ABC and Borello Tests
Review all independent contractor relationships routinely. Apply the ABC Test, and where applicable the Borello factors for the professions they still cover, to every arrangement that could be ambiguous. This is not a one-time exercise: a change in how work is performed, or in the underlying agreement, should prompt a fresh review.
Notify Clients and Correct Misclassifications
When a problem surfaces, tell the client, set out the risk, and present a remediation plan. That plan may include:
- Amending prior filings, converting 1099s to W-2s where appropriate.
- Submitting corrected tax returns.
- Adjusting payroll processes to reflect proper withholding and reporting.
- Reissuing forms or retroactively correcting documentation.
Early correction can narrow the scope of potential penalties and puts the client in a better position if an audit does begin.
Involve Counsel Early
The opening stages of an EDD audit, the entrance interview and the initial document request, tend to set its direction. Involving counsel at that point can help keep the audit within a sensible scope, preserve appeal rights, and make sure the process is followed properly. Our guide to what happens during a payroll tax audit sets out the sequence.
An Action Plan
| Action step | Purpose |
|---|---|
| 1. Inventory 1099 relationships | Review each contractor file for role, degree of control, and business independence. |
| 2. Apply the ABC Test, plus Borello where relevant | Use the criteria codified in AB 5, together with EDD’s DE 44 guidance, for classification decisions. |
| 3. Agree a client communication protocol | Where classification is doubtful, raise it with the client and set out a reclassification or documentation plan. |
| 4. Build a document correction workflow | Record identified errors, amend the affected filings, and reissue the correct forms. |
| 5. Engage counsel | Arrange representation for entrance interviews and within appeal windows. |
| 6. Establish preventive policies | Adopt classification checklists, contractor controls, and periodic re-evaluation. |
If a Client Is Facing an Audit
Classification questions are rarely clear-cut, and the same contractor arrangement can look defensible or indefensible depending on how it is documented. Where a firm has inherited client files it did not set up, a review before any audit notice arrives is usually time well spent.
If you are unsure how these rules apply to a particular client arrangement, or a client has already received an audit notice, speaking with an attorney can help you understand the options. We work with accounting firms and their clients on EDD payroll tax audits, from the entrance interview through to assessment appeals and post-audit compliance.
