What California Form DE 9C (2018) Is For
The California Form DE 9C is the employee-level wage report that supports the quarterly contribution return and wage report. It lists employee wages, withholding details, and Social Security number information that the Employment Development Department uses to verify employment tax reporting. Every employer with California payroll files the form quarterly, and electronic filing through the EDD e-Services website is required under the e-file and e-pay mandate.
When You’d Use California Form DE 9C (2018)
Employers file DE 9C each quarter to report employee wage data that supports entries on the California Form DE 9. Late filing occurs when the deadline passes without submitting required payroll records, and amended filing occurs when wage amounts, names, or identification numbers need correction. Filing deadlines follow the standard Payroll Tax Deposit calendar unless adjusted by Executive Order N-40-20 or Executive Order N-66-20.
Key Rules or Details for 2018
- Electronic filing requirement: Electronic filing applies to all employers, and you can avoid penalties by filing through e-Services for Business and meeting the e-pay mandate requirements. The Employment Development Department assesses $20 per employee when electronic filing is not used.
- Accurate employee data: Correct employee wage data is essential, and you can prevent delays by reporting accurate Social Security number information and verifying employee wages before submitting the salary report. This form ensures the tax agency processes totals correctly.
- Understanding wage categories: Total wages differ from taxable wage limit amounts, and you can avoid errors by understanding State Disability Insurance and Employment Training Tax rules. This ensures accurate calculation in accordance with California regulations.
- Separate reporting needs: Some employees require separate filings, and you can prevent issues by following special reporting rules for independent contractor corrections or professional employer organization arrangements. This process ensures that contribution return and wage report entries are consistent.
- Quarterly deadlines: Quarterly filing deadlines apply, and you can avoid penalties by submitting through the EDD e-Services website on or before the due date. This ensures compliance with Government Code section 11346.1(d).
Step-by-Step (High Level)
Step 1: Gather payroll information
Collect employee wages, totals subject to State Disability Insurance, and Employment Training Tax details. Confirm Social Security number accuracy and verify your Federal Employer Identification Number for all entries before preparing your quarterly report of wages and withholdings.
Step 2: Access e-Services for Business
Log in to the EDD e-Services website and select the quarterly contribution return and report of wages section. Use data import or manual entry to upload employee wage records in a format that adheres to the file instructions.
Step 3: Enter employee wage data
Input employee wages, identification numbers, and contribution return totals for the quarter. Ensure entries reflect accurate taxable wage limit information and align with employment tax reporting requirements under Title 26 of the United States Code.
Step 4: Review totals before filing
Confirm the accuracy of employee wages, withholding entries, and contribution return calculations. Verify that the DE 88 payment coupon information matches payroll service totals, and confirm your file attachment is correct.
Step 5: Submit your filing
Submit the DE 9C electronically through the EDD e-Services website, ensuring you comply with the e-file and e-pay mandate. Save the certificate of compliance for your records and maintain all payroll checks and supporting payroll records.
Step 6: File amendments if needed
Use the system’s adjustment feature when updating employee data or correcting wage amounts. Amended filings apply when resolving errors involving employee wages, identification numbers, or reports of wage entries that affect DE 9 totals.

Common Mistakes and How to Avoid Them
- Incorrect wage categories: Employers sometimes treat all wage fields as identical, but you can avoid errors by reviewing guidelines for Employment Training Tax and disability insurance. This ensures totals match each employee’s actual wages.
- Filing without electronic submission: Some employers ignore electronic filing rules, but you can prevent penalties by using the Electronic Filing Guide instructions. This ensures compliance with the e-file and e-pay mandate.
- Wrong Social Security number entries: Identification errors cause delays, but you can avoid mismatches by verifying Social Security number accuracy before filing. This ensures that wage data posts are reported correctly.
- Late filing issues: Missing deadlines increases penalties, but you can prevent such incidents by following the payroll tax deposit schedule. This ensures timely submission for every quarterly contribution return.
- Improper amended filings: Incorrect corrections cause further delays, but you can avoid these problems by submitting updates only when necessary. This ensures amended contribution return entries remain accurate.

What Happens After You File
The Employment Development Department reviews your DE 9C submission and updates quarterly employment tax accounts. Employee wage data posts to state systems used for disability insurance, unemployment rate calculations, and Employment Training Tax reporting. If changes are made to your entries, the tax agency will verify the corrections according to California rules and may request additional documents to ensure compliance with the emergency rules outlined in Senate Bill 833 and Government Code section 11343.4(b)(3).
