California employers must stay on top of quarterly payroll reporting, and Form DE 9C is one of the most important filings in that process. It reports detailed employee wage and withholding information to the Employment Development Department, or EDD.
When filed correctly and on time, the California Quarterly Wage Report Form DE 9C helps keep payroll records accurate and tax accounts in good standing. It also supports compliance with state programs tied to wages, contributions, and withholdings.
What Is California Quarterly Wage Report Form DE 9C?
Form DE 9C, officially called the California Quarterly Contribution Return and Report of Wages (Continuation), is a mandatory employer filing in California. It lists each employee’s wages and tax withholding details for the quarter.
This form works alongside Form DE 9. The DE 9 is the summary return, while the DE 9C is the detailed continuation report showing individual employee records.
Why California Employers File Form DE 9C
The main purpose of the quarterly wage report is to give the state a complete view of taxable wages and withheld amounts. That includes wages subject to Unemployment Insurance, Employment Training Tax, State Disability Insurance, and Personal Income Tax withholding.
For employers, this filing is not just an administrative task. It is part of remaining compliant with California payroll tax rules and maintaining accurate wage records for each reporting period.
Wage and Tax Information Reported on DE 9C
The DE 9C typically includes employee-specific wage detail rather than just business-level totals. That means the report must reflect individual compensation information for the quarter.
Employers generally use it to report:
- UI taxable wages
- ETT taxable wages
- SDI taxable wages
- PIT wages and withholdings
California Quarterly Wage Report Form DE 9C Filing Deadlines
The DE 9C must be filed every quarter, and the deadline depends on the reporting period. Missing the deadline can lead to penalties, interest, and other compliance issues.
California’s quarterly due dates are scheduled as follows:
- First Quarter (January, February, March): Due April 1, 2026; delinquent after April 30, 2026
- Second Quarter (April, May, June): Due July 1, 2026; delinquent after July 31, 2026
- Third Quarter (July, August, September): Due October 1, 2026; delinquent after November 2, 2026
- Fourth Quarter (October, November, December): Due January 1, 2027; delinquent after February 1, 2027
If a due date falls on a Saturday, Sunday, or legal holiday, the next business day becomes the timely filing date. That rule gives employers a little flexibility when the calendar works against them.

How To File California Quarterly Wage Report Form DE 9C
California requires employers to file Form DE 9C electronically. This has been mandatory for all employers since January 1, 2018.
The EDD’s e-Services for Business portal is the main filing method. Employers can use it to submit payroll reports, make deposits, view tax rates, update business information, and manage their accounts.
Using The EDD e-Services for Business Portal
The online portal is designed to simplify payroll tax compliance. It lets employers handle reporting and account management in one place instead of using separate systems.
Because the DE 9C is electronic, employers should make sure their payroll software or internal records are ready before the quarter closes. Good payroll setup can prevent last-minute errors and missed submissions.
Common California Quarterly Wage Report Form DE 9C Errors
Payroll reporting errors can create headaches for employers, especially when employee information or wage totals do not line up with state records. Since the DE 9C is a detailed report, small mistakes can cause bigger compliance problems.
Some common issues include incorrect Social Security numbers, missing employee wage lines, wrong taxable wage amounts, and mismatched totals between the DE 9 and DE 9C. Employers should review each report carefully before filing.
Tips for Avoiding DE 9C Filing Mistakes
Accurate payroll records make the reporting process much easier. Employers should reconcile wages each quarter and confirm that withholding amounts match payroll system data.
It also helps to verify employee names, identification numbers, and tax classifications before submission. A quick review can reduce the risk of corrections or penalties later.

California Quarterly Wage Report Form DE 9C Penalties
Failing to file the DE 9C on time can cost employers money. If the report is not submitted within 15 days of the demand date, the EDD may charge a penalty of $20 for each unreported employee, plus interest unless there is good cause for the delay.
Penalties can become especially burdensome for businesses with larger workforces. That makes timely filing and accurate recordkeeping essential for every California employer.
Best Practices for California Quarterly Wage Report Form DE 9C Compliance
Staying compliant with California wage reporting rules is easier when employers build a consistent quarterly process. Payroll should be reviewed throughout the quarter rather than left until the deadline approaches.
Strong compliance habits can also help reduce filing corrections and late fees. That often starts with organized payroll records and a clear internal calendar.
Build a Quarterly Filing Routine
A quarterly checklist can help employers match wage data, withholding amounts, and employee records before submitting the report. This is especially useful for businesses with changing staffing levels.
Employers should also confirm that both pieces of the filing, the DE 9 and the DE 9C, are completed together. Filing one without the other can create account discrepancies.
Work With Payroll Records Early
Waiting until the deadline increases the chance of mistakes. Reviewing payroll data early gives employers time to fix missing or incorrect information before the report is due.
That practice is also helpful if an employer needs to correct a prior quarter or update employee records. Fast access to payroll documentation makes the process much smoother.
California Quarterly Wage Report Form DE 9C and DE 9 Together
The DE 9 and DE 9C are designed to work as a pair. The DE 9 summarizes the employer’s liability, while the DE 9C provides the detailed employee wage continuation information behind that summary.
When both forms match, the EDD can more easily reconcile payroll tax reporting for the quarter. If the totals do not align, the employer may need to correct the filing.

Final Thoughts on California Quarterly Wage Report Form DE 9C
California’s DE 9C is a required quarterly wage report that plays a key role in payroll tax compliance. It captures wage and withholding details for each employee and works with the DE 9 to complete the state’s reporting process.
By filing electronically, meeting the quarterly deadlines, and keeping payroll records accurate, employers can avoid penalties and keep their accounts in good standing. A careful routine makes the process far less stressful and much easier to manage.
