What California Form DE 9ADJ (2025) Is For
California Form DE 9ADJ (2025) helps employers correct earlier wage reports filed with the California Employment Development Department. It supports adjustments to employee wages, personal income tax withholding, State Disability Insurance, and Employment Training Tax amounts reported through DE 9 or DE 9C. Form DE 9ADJ ensures accurate employment tax records that support the unemployment insurance program.
Employers use this form when previously submitted information on the Quarterly Contribution Return and Report of Wages contains errors. The California Employment Development Department relies on correct data to maintain accurate employee records and determine unemployment insurance contributions. The DE 9ADJ Form reconciles earlier entries with proper amounts and updates the Contribution Return and Report of Wages accordingly.
When You’d Use California Form DE 9ADJ (2025)
Employers file Form DE 9ADJ after discovering incorrect wage amounts, wrong Social Security number entries, or inaccurate employment tax details in prior filings. These corrections can involve Unemployment Insurance, California PIT, State Disability Insurance, or other DE9 forms used for statewide payroll reporting. The form supports wage corrections without requiring the replacement of the original Quarterly Contribution Return.
This form is used only after the original DE 9 or DE 9C submission occurs for the quarter involved. Employers cannot file the application form until they have submitted their initial Report of Wages. The California EDD reviews each correction to ensure compliance with California's tax regulations and accurate employee wages.

Key Rules or Details for 2025
California requires employers to complete one adjustment form per quarter when submitting wage adjustments or corrections to employment taxes. Separate submissions are needed for additional quarters to ensure proper processing under California state reporting rules. Employers must complete Sections I and II to provide accurate employer identification and clear explanations of any adjustments made.
The statute of limitations allows refund claims to be filed within specific timelines, as outlined by the Employment Development Department. Employers may still correct errors, but this may increase liability beyond the established timeline. Refunds, however, expire after the deadlines pass. Refund amounts require proper documentation, especially when correcting Personal Income Tax or California PIT withholding.
Step-by-Step (High Level)
- Step 1: The employer gathers wage reports, DE 9 forms (including California Form DE 9), payroll data, and the names of each employee to prepare accurate wage adjustments for the DE 9ADJ form.
- Step 2: The employer reviews errors, confirms employer information, and ensures that the Quarterly Contribution and Wage Adjustment Form aligns with the ABC test, the California Values Act, and SB 54 limits on immigration enforcement.
- Step 3: The employer adds UI or ETT changes to the application form, attaches the required records from the Internal Revenue Service, and notes any issues that affect Paid Family Leave or Public Health Division reporting.
- Step 4: The employer submits the form through e-Services for Business or mails the form DE 9 and then uploads the required files for San Francisco, San Jose, Daly City, or Solano County worksites.
- Step 5: The employer uses the Signature Tool to sign and maintains records for natural disasters, public safety threats, Hi-Lo siren activations, food safety updates, social media notices, and coordination of Health Officers’ measles vaccinations.

Common Mistakes and How to Avoid Them
Frequent IRS processing delays arise from preventable submission errors that occur on required filings. Early identification of these issues supports accurate review and strengthens overall compliance outcomes for Internal Revenue Service procedures.
- Missing Signatures: This mistake occurs when required signature fields remain unsigned, and filers must verify each Signature Tool authorization before submitting the application form.
- Mismatched EINs: This error occurs when the EIN on supporting schedules differs from the one on the return, and filers must confirm uniform identifiers across wage reports and DE9 forms.
- Incomplete Forms: This issue occurs when mandatory lines remain blank, and filers must review every entry, including employer information and employee name data.
- Missing Attachments: This mistake arises when required schedules or Form 1099-MISC documents are omitted, and filers must include all supporting materials.
- Payment Timing Errors: This issue occurs when payments post after IRS deadlines, and filers must remit amounts on the required dates.
What Happens After You File
The California EDD verifies that a corresponding original DE 9 or DE 9C exists for the corrected quarter. The agency reviews wage corrections, evaluates tax adjustments, and confirms accurate entries for State Unemployment Insurance and Personal Income Tax. Electronic filing through e-Services for Business generally speeds the processing timeline.
Approved adjustments update employer accounts and employee wage records used in the unemployment insurance program. Refunds apply to outstanding liabilities before issuance, while underpayments require timely settlement. Employers may receive requests for additional information when documentation does not clearly support the correction.
FAQs
What is the purpose of the DE 9ADJ?
The DE 9ADJ allows employers to correct wage adjustments on prior wage reports, including entries from DE 9 forms and California Form DE 9. It supports accurate employer information used in the unemployment insurance program.
How does electronic filing work?
Electronic filing uses e-Services for Business, which accepts the application form and documents for each employee. Filers may upload supporting schedules, such as Form 1099-MISC, when submitting the DE 9ADJ form.
Can multiple quarters be corrected at once?
No, each quarter requires a separate DE 9ADJ because the form DE 9 records must match specific periods. This separation helps prevent mismatches affecting Paid Family Leave calculations and Internal Revenue Service reconciliation.
What records should be reviewed before filing?
Filers review wage reports, payroll records, and employee name data to confirm accuracy. These checks ensure accurate entries on the Quarterly Contribution and Wage Adjustment Form, which helps reduce processing issues in San Francisco or San Jose.
Who provides guidance when issues arise?
The Taxpayer Assistance Center offers guidance on DE 9ADJ requirements and clarifies wage adjustments. Agencies such as the Public Health Division or County Land Use Commission may request records during public outreach campaign reviews in Daly City.
