What California Form DE 9C (2015) Is For

The California Form DE 9C supports the quarterly contribution return and report of wages by listing wage reports for each employee, showing wages paid and taxes withheld for the quarter. The California Employment Development Department uses this reporting form type to verify employment tax returns, update UI reports, and maintain California payroll records for both employers and workers.

When You’d Use California Form DE 9C (2015)

Employers use DE 9C when submitting a quarterly contribution return for any quarter in which wages paid must be reported to the California EDD. This includes quarters with active payroll, amended reporting, or filings submitted under the e-file and e-pay mandate using approved electronic filing options.

Key Rules or Details for 2015

  • Accurate employee reporting: Employers report each worker’s wages paid and taxes withheld to support the contribution return and report of wages, ensuring California state reporting rules are followed, and all totals match the CA DE 9 form.

  • Electronic submission options: Electronic filing is encouraged through approved systems, allowing employers to meet the e-file and e-pay mandate and follow the electronic filing guide instructions, which cover wage reports and quarterly submissions.

  • Use of correct identifiers: Every filing includes an employer account number and EDD number, enabling the California Employment Development Department to assign reports and maintain accurate employment tax records.

  • Wage category distinctions: Total subject wages, PIT wages, and PIT withheld may differ. Employers follow the Insurance Code and Health and Safety Code requirements when determining the correct quarterly amounts.

  • Household employer rules: A household employer may instead use the California Employer of Household Worker(s) Annual Payroll Tax Return if eligible, although some elect to report quarterly using the DE 9C.

  • Special wages and deductions, including sick leave, disability insurance, and independent contractor reclassifications, require careful review to ensure accurate reporting under employment laws and Government Code Section 100504.

Step-by-Step (High Level)

Step 1: Gather employer and employee data

Collect the quarter’s payroll records, including wages paid, account number details, and taxes withheld, ensuring every employee appears on your report and that all totals match your payroll tax deposits.

Step 2: Access the reporting platform

Open your electronic filing system or PDF platform and choose the DE 9C under the reporting form type drop-down menu, confirming you select the correct quarter before entering your wage reports.

Step 3: Enter wages and totals

Input wages paid, wage categories, and taxes withheld for each employee, reviewing the totals for accuracy and ensuring entries match your payroll system and comply with the quarterly contribution return.

Step 4: Review and complete certification

Verify accuracy, apply electronic signatures using the signature tool, and confirm your EDD number and employer account number are entered correctly before finalizing the contribution return and report of wages.

Step 5: Submit and save records

Submit your DE 9C through your chosen system, then save the preview form, print the form confirmation, or download the tutorial receipt to maintain documentation supporting California's reporting requirements.

Common Mistakes and How to Avoid Them

  • Incorrect wage totals: Employers sometimes enter wages paid incorrectly, resulting in totals that fail to match the quarterly contribution return. You can avoid this by comparing all wage categories directly with your payroll register before submitting the form.

  • Missing employee details: Some filers omit a Social Security number or other information, which delays processing. You can prevent this by reviewing every wage entry carefully and confirming identification information before electronic filing.

  • Late quarterly filing: Missing a due date results in penalties and interest under Section 6522 and Senate Bill 833. You can avoid this by setting reminders for each quarterly contribution return deadline to ensure timely submission.

  • Choosing the wrong form: Employers sometimes select an incorrect reporting form type, such as Form DE-9 instead of DE-9C. You can avoid this by confirming the quarter and form name through the drop-down menu before completing wage reports.

  • Inconsistent wage categories: PIT wages and total subject wages occasionally mismatch due to classification errors. You can prevent this by reviewing the California Department of Industrial Relations guidance and applying consistent definitions across payroll entries.

What Happens After You File

Once the DE 9C is submitted, the California EDD updates each employee’s wage history and matches totals with the CA DE 9 form for the quarter. The department may issue notices if wage reports contain errors, and employers can submit adjustments using California DE 9C Options when correcting employment tax returns under relevant California reporting rules.

FAQs

What information does the DE 9C require for California state reporting?

The form requires each employee’s name, Social Security number, wages paid, and taxes withheld so the California Employment Development Department can verify payroll and maintain accurate UI reports.

How do I fix errors on a previously filed DE 9C?

You submit an amended wage report using California DE 9C Options, entering corrected wage amounts and updated information so totals align with your quarterly contribution return for that same period.

Is electronic filing required for DE 9C in 2015?

Electronic filing is strongly encouraged due to the e-file and e-pay mandate. Most employers use approved systems, ensuring that filings comply with the electronic filing guide and support accurate employment tax reporting.

Why do wages differ between categories on the DE 9C?

Wage categories differ because total subject wages, PIT wages, and taxes withheld follow separate rules under the Insurance Code, employment laws, and state withholding requirements for wage filings.

Can household employers use this form?

Some household employers use this form, while others file the California Employer of Household Worker(s) Annual Payroll Tax Return, depending on their reporting preference and eligibility for annual California state reporting.

What other forms relate to payroll taxes?

Other forms related to payroll taxes include IRS Form 941, Form 940, Form 944, Form 945, and Federal Form 8879-EMP, as well as applicable state withholding and unemployment tax forms such as Form IL-941, Form TC-941, Form NCUI-101, Form A1-APR, and Form G-7.

How do I confirm the correct account number appears on my filing?

You review the employer account number and EDD number shown on your DE 9C, ensuring they match your records before submitting through your system’s PDF platform or electronic filing tool.
