Nationwide Guide to EDD Payroll Tax Audits

How California’s Employment Development Department audits employers, what the auditor is really testing, and how to protect your business. A plain-English rewrite of the EDD’s own Tax Audit Guidelines (DE 40).

Most employers learn about an EDD audit the same way. An envelope arrives with an Inquiry Regarding Records (DE 996), a pre-audit questionnaire, a list of records, and a deadline that already feels too close. The letter is polite. The process behind it is anything but casual.

The EDD publishes the manual its own auditors follow. It is called the Tax Audit Guidelines (DE 40), and the current edition (Rev. 4, 12-23) runs 118 pages of code sections, form numbers, and internal procedure. This guide boils that manual down to what an owner, CFO, or controller actually needs to know: how audits start, what gets tested, how worker status is decided, how penalties stack, and where your appeal rights live and when they expire.

I’m Mike Habib, a federally licensed Enrolled Agent. My firm, Mike Habib, EA, is a national tax representation firm, and EDD audit defense is a large share of the work I handle for California employers and for out-of-state companies with California workers. Everything below tracks the EDD’s own guidelines. Where I add advice from the representation side of the table, I say so.

1. Why an EDD Audit Reaches Far Beyond California

The EDD administers four payroll taxes: Unemployment Insurance (UI), Employment Training Tax (ETT), State Disability Insurance (SDI), and California Personal Income Tax (PIT) withholding. Under California Unemployment Insurance Code (CUIC) section 13020, an employer must withhold PIT on wages paid to California residents for work performed inside or outside the state, and on wages paid to nonresidents for work performed in California. A company based in Texas, New York, or Florida with remote staff in Los Angeles is squarely inside the EDD’s reach.

Findings also travel. The guidelines tell auditors to inform employers that the EDD and the IRS have an information exchange agreement and that the audit file may be made available to the IRS. The EDD Director also chairs California’s Joint Enforcement Strike Force on the Underground Economy (CUIC section 329), which pools information across state agencies. And because the U.S. Department of Labor sets the audit standards every state’s unemployment program must follow, an EDD reclassification often signals the same exposure with the IRS and with workforce agencies in other states. That is why I approach every EDD case as a nationwide problem, not a California-only one.

2. Who Runs the Audit and Where the Power Comes From

EDD Audits are handled by the Field Audit and Compliance Division (FACD) of the EDD’s Tax Branch, organized into Northern and Southern regions with nine Area Audit Offices. A separate unit, Compliance Development Operations, generates leads through informant tips, data matching, and joint on-site inspections with other agencies. Its two Underground Economy Sections exist specifically to find unreported payroll.

The auditor’s authority is broad, and it helps to know exactly how broad:

• Records on demand. CUIC section 1092 makes employer records open to inspection and copying by EDD representatives at any time during business hours. Willfully failing to make required records available is a violation under CUIC section 2105.
• The burden is on you. Title 22, California Code of Regulations (CCR) section 1085-5 requires even businesses that do not believe they are employers to keep records, and places the burden on the business to prove it is not an employing unit.
• Subpoenas. Under Government Code sections 11180 through 11182, designated FACD staff can administer oaths and issue an administrative Subpoena or Subpoena Duces Tecum (DE 297) to compel testimony or documents.
• Bank records, with limits. EDD staff generally cannot obtain your financial records from a bank or credit union without either your signed Customer Authorization (DE 298C) or an administrative subpoena. If you sign, the examination must be completed within the 60-day authorization period, and you must be notified on a DE 299C within 30 days after the examination.

The guidelines also bind the auditor. They must act professionally, may not give opinions on any law other than the CUIC, must keep your information confidential, and must include facts that support your position in the audit report, not only facts that support the EDD’s.

3. How Businesses Are Selected for an EDD Audit

Federal rules require the EDD to classify every audit as either a verification audit or a request audit. Verification audits start without specific knowledge about your business. You may be picked based on payroll size, number of workers, location, industry, or a combination. Request audits start because something specific pointed to you. The guidelines list the usual triggers:

• A former worker files a UI or SDI claim and no wages, or the wrong wages, are on file for them.
• A worker asks the EDD in writing to decide whether they were an employee.
• Tips from the public, other EDD offices, or Compliance Development Operations investigations.
• Unfiled returns that produced a system-generated estimated assessment.
• Industries the EDD considers prone to underreporting, requests from other states, and bankruptcy or probate proceedings.

One of the most direct paths into an audit is a benefit claim from someone you paid on a Form 1099. The claim itself shows the EDD a worker with services but no reported wages, and the audit that follows rarely stops at that one person.

4. The First Letters, the First Deadlines, and Who Should Answer

An audit opens with the Inquiry Regarding Records (DE 996), which names the purpose of the audit and the period under review. It comes with a Pre-Audit Questionnaire (DE 996Q), which the EDD expects back within 14 calendar days, and the Information Sheet: Employment Tax Audit Process (DE 231TA), which lists the records you will be asked for. The auditor sets a 15-day follow-up on every DE 996. An Audit Appointment (DE 996C) then fixes the date, time, and place. You may reschedule if the date does not work.

Two practical points. First, the questionnaire is evidence. How you describe your workers and your business on the DE 996Q will be quoted back to you, so have your representative review it before it goes out. Second, a representative can only speak for you once a Power of Attorney Declaration (DE 48) is on file with the EDD. File it before the first phone call.

Ignoring the process is the worst option. If someone served with a subpoena fails to appear or produce records, the Area Audit Office refers the matter to the Collection Division’s Special Procedures Group, which forwards it to the Attorney General. The Attorney General can ask the Superior Court for an order to show cause, and failure to respond to that order can lead to a bench warrant. Meanwhile, the audit office may simply issue an estimated assessment.

5. The Audit Period and the Records You Will Be Asked For

A standard EDD payroll tax audit covers three years, meaning the 12 most recently completed calendar quarters. When returns were never filed, the period can be longer. Records typically requested include check registers, the general ledger and journals, payroll records, cash disbursement records, licenses, written agreements, federal and state income tax returns, Forms 1099 and California Form 599, Forms W-2, and Forms W-4 and DE 4.

One detail worth knowing: income tax returns appear on the request list, but the guidelines themselves acknowledge that judicial precedent prevents the EDD from requiring an individual or employer to produce income tax returns through a subpoena. Whether to provide them voluntarily is a strategic decision, not an automatic one. Electronic records count as records, and large employers (100 or more workers reported in the current or prior calendar year) should expect the auditor to ask early about system access and data exports.

6. The Entrance Interview and the Entity Check

The entrance interview sets the tone. The auditor meets with the owners or the people who run the books, explains the scope, estimates how long the audit will take, and asks questions guided by the Report of Field Auditor (DE 6775) and Audit Schedule (DE 6776). The guidelines tell auditors to learn how the business operates and why any independent contractors are used, so that answer should be prepared, accurate, and consistent with your paperwork.

The auditor also verifies the entity itself: that the legal form on EDD records matches reality (a sole proprietorship that is really a corporation is a problem), that the date payroll began and any change in ownership are supported, and, where possible, that the business physically exists at its address.

7. What the Auditor Tests in Your Payroll

• Acknowledged payroll test. Reported payroll is reconciled to your accounting records for at least four representative quarters.
• Payroll posting test. Wages in your books are compared with your copies of the Quarterly Contribution Return and Report of Wages (DE 9 and DE 9C) and with what posted to your EDD account.
• Taxable wage test. The auditor checks that you applied the UI taxable wage limit under CUIC section 930 correctly. The SDI wage limit (section 985) was repealed effective January 1, 2024, so SDI now applies to all subject wages. Under section 930.1, UI wages you paid and reported to another state can count toward the California limit for an employee transferred to California in the same calendar year, a point multistate employers often miss.
• PIT tests. PIT withheld is compared with PIT reported, and withholding calculations are checked. A Form W-4 or DE 4 that was altered, or that the employee admits is false, is invalid. You must then withhold as if the employee were single with zero allowances, unless an earlier valid form is on file.

8. Worker Classification: Where Most EDD Audits Are Won or Lost

Since January 1, 2020, CUIC section 621(b) presumes anyone paid for labor or services is an employee unless the hiring business proves all three parts of the ABC test:

• A: The worker is free from your control and direction in performing the work, both under the contract and in fact.
• B: The work is outside the usual course of your business.
• C: The worker is customarily engaged in an independently established trade, occupation, or business of the same nature.

Failing any one prong makes the worker an employee. Certain occupations and relationships listed in Labor Code sections 2776 through 2784 are judged instead under the multi-factor Borello standard, and some professions follow rules in the Business and Professions Code. For services before 2020, the common law test applies: the central question is whether you had the right to control the manner and means of the work, and the right to fire at will is strong evidence of control. Secondary factors include whether the worker runs a separate business, the skill involved, who supplies tools and the workplace, how long the relationship lasts, how the worker is paid, whether the work is part of your regular business, and what both parties believed they were creating.

Some workers are employees simply because the statute says so:

Multi-party arrangements get their own rules. Under section 606, if you know, or should know, that a worker classified as your employee is using helpers, those helpers are your employees too, even if you never hired or paid them. Under section 606.5, a staffing or leasing company is the employer only if it performs all seven functions the statute lists, including setting pay, paying workers from its own account, and holding the right to hire and fire. Fall short of any one, and the supplier is treated as paying wages as the client’s agent.

The guidelines require the auditor to explain the process, ask you why you treated each worker as a contractor, accept your evidence without arguing the point on the spot, explain the decision at an exit interview, and offer a conference with a supervisor. Treat that question, why are these people contractors, as the most important one in the audit, and answer it with documents: business licenses, the worker’s other clients, advertising, invoices, insurance, and their own tools and investment.

9. PIT Assessments and the Abatement Process

Under CUIC section 13070, the employer is liable for PIT it should have withheld. Section 13071 offers relief: if the workers reported the wages on their own California returns, the EDD will not collect that tax again from you. Abatement removes the tax, but it does not remove penalties and only partly reduces interest, and it is the employer’s job to pursue it. The tools are the Declaration (DE 6028P), which you sign to confirm Forms 1099, W-2, or Schedules K-1 were timely filed with the IRS and the Franchise Tax Board, and the Claim for Adjustment or Refund of Personal Income Tax (DE 938P), signed by workers who certify they paid.

Abatement is not available when audited PIT withheld exceeds PIT reported, when W-2 withholding exceeds what was reported, when wages are estimated and workers cannot be identified, or when tax was withheld but not reported and the records cannot show how much. A separate remedy, section 1136, can cancel tax, penalty, and interest together, for example when new facts show a worker was a true contractor or a payment was not wages.

10. EDD Penalties and How They Stack

Rates below are those the EDD applies for periods beginning with the third quarter of 2014. Most were 10 percent, or $10 per item, before then.

The definitions matter as much as the rates. Title 22 CCR section 1127-1 defines negligence to include failing to make a status determination about a worker and failing to ask the EDD for a ruling when status is questionable. Intentional disregard includes failing to report a worker after your accountant advised you to. In other words, the 15 percent section 1127 penalty is the default outcome in most misclassification audits, and good-cause arguments (see the EDD’s DE 231J waiver policy) have to be built with facts, not assertions. Interest runs on top of all of it.

11. The Closing Interview, Proposed Assessment, and Conferences

At the end of fieldwork the auditor holds a closing interview and presents a Proposed Notice of Assessment (DE 6517P). The auditor is required to explain how each tax, penalty, and interest figure was computed, which items lack petition rights, how PIT abatement works, the date the assessment will become final, payment options including installment agreements, and state tax lien consequences. You will also receive a Notification of Audit Results and Right to Review Audit File (DE 105), which lets you inspect the closed file before deciding whether to appeal.

My advice: do not concur at the closing interview just to end the meeting. You are entitled to a pre-assessment conference with the auditor’s supervisor whenever the audit produces an assessment, and a post-assessment conference is available in several situations, including when you have new documentation. Any disagreement you voice is recorded in the auditor’s report. If records were missing and the auditor estimated, you may receive an Audit 10-Day Letter (DE 6548) with the proposal. Use that window to produce records before the estimate becomes an actual assessment.

12. Notices of Assessment, Time Limits, and Personal Liability

The formal bill is the Notice of Assessment (DE 6517), sent by certified mail when it exceeds $1,000 or is a jeopardy assessment. Ordinary billings for penalties, interest, or self-reported amounts carry no appeal rights unless they contain computation errors. The EDD’s time to assess depends on what happened:

Be careful with the Extension of Time for Making Assessments and a Claim for Refund or Credit (DE 1977). Signing it gives the EDD more time to assess you, although it also preserves your own refund claims for the same quarters.

Liability can reach beyond the business. Section 1735 allows memorandum assessments against responsible officers or others in charge of a corporation’s affairs who willfully failed to pay. Under sections 1731 through 1733, a buyer of a business, or of substantially all its assets (the EDD treats less than 80 percent as not substantially all), is liable up to the purchase price unless it obtains a statement of amount due or a release certificate. The EDD must issue that statement within 30 days of a request, and silence counts as a clean certificate. A jeopardy assessment under section 1137, used when the EDD believes collection is at risk (insolvency, below-value asset transfers, dissolution, owners leaving California, or a fraud penalty), is final immediately.

13. Your Appeal Rights and Refund Deadlines

• Petition for reassessment: due within 30 days after service of the Notice of Assessment (CUIC section 1222). An Administrative Law Judge (ALJ) may grant another 30 days for good cause. Mailed notices add 5 days for a California address, 10 days for an address elsewhere in the United States, and 20 days outside the country.
• Jeopardy assessments: a petition is timely only if filed within 10 working days, and the amount stays due immediately.
• At the hearing: the ALJ can decrease or increase the assessment (section 1223). Prepare as if both outcomes are possible.
• Pay-and-convert strategy: paying the assessment in full before the ALJ or the California Unemployment Insurance Appeals Board (CUIAB) rules converts the petition into a refund-claim appeal (section 1179.5), which can open a faster path to court.
• Refund claims: under section 1178, file by the latest of 3 years from the last day of the month following the quarter, 6 months after an assessment becomes final, or 60 days after the overpayment. If the EDD does not respond within 60 days, the claim may be treated as denied and appealed.
• Benefit charges: a protest of charges to your reserve account is due within 60 days after mailing (section 1034).

The refund rule is easier to see with the EDD’s own example. An assessment for the fourth quarter of 2019 is issued May 1, 2020, becomes final June 1, 2020, and is paid June 30, 2021. The three windows close on January 31, 2023 (three years after the month following the quarter), December 1, 2020 (six months after finality), and August 29, 2021 (60 days after payment). Because the latest date controls, the claim is timely through January 31, 2023. If the EDD denies a claim in writing, the denial becomes final 30 days after service unless you file a petition for review.

Two more points the guidelines make that employers rarely hear. The EDD can cancel or reduce an erroneous assessment on its own under section 1136, even after it is final, as long as no ALJ or CUIAB decision on the merits has been issued and the assessment has not been paid. And if you make a payment “under protest,” that payment is not a refund claim by itself. The claim must be in writing and state the specific grounds, the period, and the amount (section 1179).

14. Special Situations for Multistate, Growing, and Changing Businesses

A large part of the DE 40 deals with situations that do not fit a single company in a single state. These are the ones that matter most to multistate and growing employers:

• Workers who split time between states. An Interstate Reciprocal Coverage Arrangement lets an employer elect to cover a worker who customarily works in two or more states under one state’s law. The employer, the employee, and each interested state must all consent, and the EDD’s FACD Audit Section approves the arrangement. Without one, the EDD applies its own coverage rules, and the same wages can be questioned in more than one state.
• Contributions paid to the wrong state. Under CUIC section 991, UI, SDI, and ETT contributions paid in error, and without negligence, to another state’s unemployment program or to a federal agency can be treated as timely in California, avoiding penalty and interest. Section 991 does not apply to PIT withholding, so withholding sent to the wrong state is still late in California.
• Ownership changes and related companies. Under CUIC section 135.1 (vertical unity of enterprise), converting a sole proprietorship into a corporation with continuity of control does not create a new employer; the history, including liabilities, follows the business. Under section 135.2 (horizontal unity of enterprise), related companies that are united through control, operation, and use can be treated as one employing unit with one account number and one contribution rate.
• Sole shareholders. A sole shareholder of a private corporation (or the only shareholder other than a spouse) who is a corporate officer can file a Sole Shareholder/Corporate Officer Exclusion Statement (DE 459) to disclaim SDI benefits. The election is effective the first day of the quarter in which it is filed and must stay in place for at least two full calendar years.
• Bankruptcy, probate, and receivership. A bankruptcy filing does not stop the EDD from auditing or issuing a notice of assessment, because issuing an assessment is an exception to the automatic stay (11 U.S.C. section 362(b)(9)(D)). Collection is a separate question handled by the EDD’s Bankruptcy Group.
• Missing records. When an employer has no wage records, the EDD will not estimate wages below the legal minimum wage, and estimates may be built from prior returns, partial records, or statements from people who know the business.

15. An EDD Audit Defense Checklist

• File the DE 48 before anyone talks to the auditor, and route every contact through your representative.
• Calendar every deadline from the mailing date, and add the out-of-state mailing extension only when it truly applies.
• Run every 1099 worker through the ABC test before the auditor does, and assemble independent-business evidence for each.
• Gather Forms 1099, W-2, and K-1 filing proof now so PIT abatement is ready when the proposal arrives.
• Request the pre-assessment conference and the audit file. Never let a proposed assessment go final by default.
• Check federal Form 941 and 940 exposure and other states’ unemployment filings for the same workers.
