The California Employment Development Department (EDD) is in charge of making sure businesses are paying their payroll taxes in California. They were set up to enforce the state’s payroll tax laws, which means they help make sure businesses are paying the right amount of taxes. This includes collecting unemployment insurance, state disability insurance, employment training tax, and personal income tax withholding.
The EDD conducts regular payroll tax audits, which are often called California EDD audits, to check that businesses are getting their tax reports right and paying the right amount of tax. All California business owners are susceptible to payroll tax audits. This guide covers what happens during a payroll tax audit in California.
Common EDD Triggers
All employers must file and pay payroll taxes. This requirement leaves all California businesses vulnerable to EDD audits. The department cracks down on employers who aren’t paying accurate amounts of payroll taxes (especially for their independent contractors).
If the EDD suspects you’re misclassifying employees to avoid paying payroll taxes, they will audit your business. However, filing late taxes, document errors, and payroll delays can trigger audits. Former workers applying for unemployment insurance can also trigger the EDD.
Worker Misclassification Issues
One of the most frequent reasons for a payroll tax audit is the misclassification of workers as independent contractors rather than employees. Under California law, particularly the ABC test, businesses must meet strict criteria to classify a worker as an independent contractor. Failure to comply can lead to substantial liabilities.
The EDD actively investigates industries where worker misclassification is common, such as construction, logistics, and gig-based services.
Discrepancies in Payroll Tax Filings
Inconsistent or inaccurate filings, such as mismatches between reported wages and tax payments can quickly draw attention. If your DE-9 or DE-9C filings do not align with other financial records, the EDD may initiate an audit.
For official guidance on employer obligations, businesses can refer directly to the California Employment Development Department, which outlines reporting requirements and compliance standards.
Employee Complaints and Claims
An employee filing for unemployment insurance or reporting unpaid wages can trigger an audit. These claims often prompt the EDD to review whether wages were properly reported and whether the worker was correctly classified.
Late Payments or Non-Compliance
Repeated late payments, missed filings, or prior compliance issues significantly increase the likelihood of an audit. Businesses with a history of irregular reporting are more likely to be flagged for review.
Random or Industry-Wide Audits
In some cases, audits are conducted randomly or as part of broader enforcement initiatives targeting specific industries. Even fully compliant businesses may be selected as part of these programs.
Although various things can tip off the EDD, random audits do occur. You should have nothing to worry about as long as you follow good practices; see our guide. 5 Ways To mitigate the risk of an EDD audits and to tackle the risk of an audit.
The Audit Processes
The main occurrence during a payroll tax audit in California is the EDD collecting documents from business owners. They also put the business under a series of tests; both occurrences involve reviewing payroll records and tax documentation. An EDD auditor will contact the employer and request paperwork. The auditor will also select a random employee and review their W2 for the tax year on file.
Initial Audit Notification
The audit process typically begins with a formal notice from the EDD. This notice outlines the audit period, identifies the assigned auditor, and lists the documents required for review. At this stage, it is critical to respond promptly and begin organizing all requested records.
Entrance Interview
The auditor will often conduct an initial meeting either in person or virtually to understand your business operations. This includes questions about:
- Nature of the business
- Payroll processes
- Worker roles and classifications
- Recordkeeping systems
This interview sets the foundation for the audit and helps the auditor determine areas of focus.
Document Review and Examination
The core of the audit involves a detailed examination of financial and payroll records. The EDD will review documents such as the following:
- Payroll registers
- Tax returns (DE-9, DE-9C)
- Employee and contractor records
- Bank statements
- General ledgers
The auditor may request additional documentation if discrepancies are identified.
Follow-Up Requests and Analysis
If inconsistencies arise, the auditor may issue follow-up requests for clarification or additional records. This phase can extend the audit timeline and increase scrutiny.
Exit Interview
Once the review is complete, the auditor will schedule an exit conference to discuss preliminary findings. This is your opportunity to provide explanations or challenge conclusions before final determinations are made.
Notice of Assessment
If the EDD determines that taxes are owed, it will issue a notice of assessment, outlining
- Unpaid taxes
- Penalties
- Interest
Employers have the right to appeal these findings within a specified timeframe. As an employer, it’s important to have the right information on hand. Don’t volunteer additional documents (as the EDD can use the information against you). Keep in mind that, given the close examination of payroll information, audits can take a long time.
Verification and Accounting Tests
As previously mentioned, the EDD auditor will put your business through a series of tests, including the Payroll Tax Verification Test, where the EDD compares the business records to their records. This ensures the payroll journal matches the one on file with the EDD. An internal accounting test assesses if you need to reclassify payments into taxable wages. The auditor will assign the test and tell you what information to provide.
Payroll Reconciliation Tests
The auditor examines the employer’s books (payroll journals, general ledger, bank records, etc.) to identify the total compensation paid to workers. Those amounts are then matched to the wage totals the employer reported on payroll tax forms (such as the Quarterly Contribution Return and Report of Wages, DE-9/DE-9C). The EDD explicitly performs a “verification that your acknowledged gross wages and taxable wages have been properly reported” as part of a full California employment tax audit. Any unreported cash payments or “off-the-books” wages are likely to be discovered and counted as taxable payroll at best and referred for California criminal employment tax prosecution at worst.
Bank Deposit Analysis
The auditor will also verify that the employer withheld the correct amount of California personal income tax (PIT) from employee wages and reported/remitted those withholdings to the EDD. This involves cross-checking payroll tax returns and employee W-2s to ensure, for example, that the total state income tax withheld on all W-2s matches the amounts the employer deposited with EDD. If the auditor finds, for instance, that an employer’s W-2 forms show more wages or withholding than was reported on the EDD returns (or /versa), it will raise immediate civil and potential criminal employment tax red flags.
Worker Classification Review
As part of the verification process, the EDD auditor reviews all payments for services to determine if everyone who should be treated as an employee was properly classified and reported on payroll. The audit will “verify that all individuals paid for services have been properly classified as either employees or independent contractors” in accordance with California state law. Misclassified workers (treated as independent contractors when they should be employees) represent unreported wages and unpaid payroll taxes in the EDD’s eyes – a primary focus of the verification test. Misclassification findings can result in significant back taxes and penalties.
How the Verification Test Works
California’s Unemployment Insurance Code (CUIC) gives the EDD broad power to audit employers and verify that UI, SDI, ETT, and state income-tax withholding have been adequately reported and paid. A standard employment tax audit covers the most recent three years (12 quarters), beginning with a single test year; if that year shows errors, or if records are missing, the examiner can expand the review and even reach back further.
The process starts with an entrance interview and a detailed Information Document Request (IDR). By law (CUIC §§ 1085, 1092), employers must produce payroll registers, earnings records, bank statements, ledgers, tax returns, DE-9/DE-9C wage reports, W-2s, 1099s, and any independent contractor agreements.
Sampling Techniques
Auditors commonly use sampling methods to review a portion of records and then extrapolate findings across the entire audit period. If errors are identified in the sample, they may be applied more broadly.
Cross-Referencing with State Data
The EDD may also cross-reference your records with data from other state agencies to identify inconsistencies. This integrated approach increases the likelihood of detecting discrepancies.
Helpful Advice: Pre-Audit Your Business
Payroll audits catch discrepancies and may lead to repayments (or penalties from the EDD). Before the official audit, you can “pre-audit” your business and catch inaccurate records and information before the EDD reviews information. When problems arise, inaccuracies won’t surprise you. Additionally, you can think of solutions to correct issues.
Conduct Internal Payroll Reviews
Regular internal audits can help identify discrepancies before the EDD does. Reviewing payroll records, tax filings, and worker classifications ensures compliance and reduces risk.
Maintain Accurate and Organized Records
Proper documentation is critical during an audit. Businesses should maintain detailed records for at least four years, including payroll data, contracts, and tax filings.
Ensure Proper Worker Classification
Given the strict requirements under California law, businesses should periodically review worker classifications to ensure compliance with the ABC test.
Respond Promptly to EDD Notices
Timely responses demonstrate good faith and can help prevent escalation. Ignoring or delaying responses may lead to additional penalties.
If You Have Received a Notice
A payroll tax audit follows a defined sequence, and most of what decides the outcome happens early: what you hand over, how consistent it is, and whether your classification decisions can be explained. Preparing before the entrance interview is worth more than arguing afterwards.
