All employers are required to electronically submit employment tax returns, wage reports, and payroll tax deposits to the Employment Development Department (EDD). You can use e-Services for Business to comply with the e-file and e-pay mandate. For more information and approved electronic filing and payment methods, visit E-file and E-pay Mandate for Employers.
The Quarterly Contribution Return and Report of Wages (DE 9) (tax return) and the Quarterly Contribution Return and Report of Wages (Continuation) (DE 9C) (wage report) are the forms most employers, including quarterly household employers, are required to file on a quarterly basis. These forms can be corrected by submitting adjustments through e-Services for Business, even if the original tax return or wage report was filed via another filing method.
Refer to the following e-Services for Business resources for guidance on how to enroll, file, pay, and submit adjustments on e-Services for Business:
General Reminders
- If you over withheld Personal Income Tax (PIT) from your employee(s) during the prior year and have issued a Wage and Tax Statement (Form W-2) to your employee(s), do not refund the PIT over withholdings to the employee nor change the PIT withholding amount on the Form W-2. The employee(s) will receive a credit when they file their California PIT return with the California Franchise Tax Board (ftb.ca.gov). Do not file a claim for refund with the EDD.
- The EDD cannot process adjustment forms if you have not filed the DE 9 or DE 9C for the quarter.
- Do not report negative amounts. If amounts were reported incorrectly, complete the adjustment form(s) for the quarter(s) in which the information was reported incorrectly.
- Complete one Quarterly Contribution and Wage Adjustment Form (DE 9ADJ) per quarter. DE 9ADJ forms submitted with annual amounts will not be processed.
- Statute of Limitations: A claim for refund must be filed within 3 years of the last timely date of the quarter being adjusted, 6 months after an assessment becomes final, or 60 days from the date of the overpayment, whichever date occurs later.
