What California Form DE 34 (2023) Is For

California Form DE 34 is used to report newly hired and rehired employees to the California Employment Development Department through the California Report of New Hires program. This reporting supports child support enforcement by helping trigger an Earnings Withholding Order process when applicable and assists agencies in matching an employee’s Social Security number to the correct record.

Employers report their California employer payroll tax account number, key identifying details, and the employee’s start-of-work date, which is the first day services are performed for wages. Because DE 34 is event-based, it is separate from quarterly wage reports such as DE 9 and DE 9C, which are filed as part of the Quarterly Contribution Return and Report of Wages.

When You’d Use California Form DE 34

An employer uses Form DE 34 whenever an employee starts work for wages in California, including many rehires that involve a new start-of-work date. The 20-day filing deadline is measured from the first day of work, not the offer date, acceptance date, or onboarding paperwork date.

Employers may file through e-Services for Business or use allowed substitute documents, such as Form W-4 or California Form DE 4, when all required DE 34 data is included. Filing DE 34 on time helps avoid penalties and keeps new hire reporting aligned with other California payroll compliance requirements.

Key Rules or Details for 2023

The filing deadline is calendar-based, meaning weekends and holidays count toward the 20-day window tied to the start-of-work date. Employers should collect complete and accurate information during onboarding, including the employee’s Social Security number, current address, and the employer’s payroll tax account information, to prevent rejections or follow-up notices.

Form DE 34 does not replace wage reports such as DE 9, DE 9C, or other Employment Development Department forms related to Unemployment Insurance, State Disability Insurance, or payroll tax deposits. Guidance in the California Employer’s Guide (DE 44) and the Household Employer’s Guide emphasizes that late or incomplete submissions may result in penalties.

Step-by-Step (High Level)

Step 1: Confirm employer identification numbers

The employer should have the California employer payroll tax account number and the Federal Employer Identification Number available before filing. Newly registered employers should confirm the account is active and correctly set up in EDD systems.

Step 2: Choose the filing method

The employer may file electronically through e-Services for Business, submit a paper DE 34, or use an approved substitute form, such as Form W-4 or California Form DE 4, when all required reporting elements are included.

Step 3: Collect employee information during onboarding

The employer should collect all required DE 34 information on or before the employee’s first workday. This includes verifying the employee’s name and Social Security number, confirming the current residential address, and documenting the start-of-work date as the first day services are performed for wages.

Step 4: Submit the report within 20 calendar days

The employer should submit Form DE 34 using the selected method and review all required fields before submission. Filing early allows time to correct errors before the deadline if needed.

Step 5: Keep proof of timely filing

The employer should retain documentation showing the submission date and method. This may include electronic confirmation details, fax transmission receipts, copies of mailed submissions, and certified mail receipts when applicable.

Common Mistakes and How to Avoid Them

Reporting the wrong start-of-work date can be avoided by defining the start-of-work date as the first day job duties are performed for wages and confirming it with a manager or HR contact.

Filing quarterly instead of per hire can be prevented by integrating DE 34 reporting into the new hire workflow and setting an internal deadline earlier than the legal deadline.

Submitting incomplete or inaccurate data can be reduced by verifying key fields, such as the Social Security number, name, and address, before submission and correcting errors promptly if a mismatch is identified.

Forgetting rehire reporting after long separations can be avoided by tracking the last day worked, calculating consecutive separation days, and treating qualifying rehires as new hires for DE 34 purposes.

Waiting until the last day can be avoided by setting internal reminders to file within 15 to 17 days after the start-of-work date and maintaining a backup submission method.

What Happens After You File

Electronic submissions through e-Services for Business typically generate a confirmation and then undergo EDD validation checks, including Social Security number matching and account verification. If an issue is identified, the employer must correct the record promptly to remain compliant.

After processing, DE 34 data is added to the New Employee Registry and may be used for child support enforcement, including the issuance of an Earnings Withholding Order. Compliance may also be reviewed by comparing DE 34 filings with DE 9C and other quarterly contribution returns and wage records.

FAQs

If the 20-day deadline falls on a weekend or holiday, does the deadline move to the next business day?

The deadline is based on calendar days and generally does not move to the next business day. Employers should plan to file early to avoid issues related to weekends or holidays.

Can multiple employees be reported on one DE 34?

Paper DE 34 forms may be used to report multiple employees, and electronic filing supports reporting multiple employees in a single session. Additional pages or submissions may be required depending on the filing method.

What should an employer do if an employee’s Social Security number appears incorrect?

The employer should request corrected information from the employee and submit a corrected report promptly, retaining documentation that shows a good-faith effort to correct the error.

Do household employers need to file California Form DE 34?

Household employers may be required to file if they meet the definition of an employer and have household employees performing services for wages in California.

If a payroll service is used, who is responsible for DE 34 compliance?

The employer remains legally responsible for compliance even when a payroll service files on the employer’s behalf. Proof of filing should be retained for each new hire.
