What California Form DE 9ADJ (2019) Is For
California Form DE 9ADJ (2019) helps employers correct previously filed payroll tax reports submitted to the California Employment Development Department after errors in wages or withholdings are identified. Employers use this Quarterly Contribution and Wage Adjustment Form when adjusting items reported initially on the DE 9 or DE 9C filings. It supports modifications involving Unemployment Insurance contributions, State Disability Insurance withholdings, and Personal Income Tax withholdings affecting employee records.
This adjustment form applies when changes are needed involving Wages Paid During specific quarters previously reported through the Quarterly Contribution Return and Report of Wages system. Employers may correct figures related to Excess Wages or amend employee information that was previously transmitted to the Employment Development Department. Accurate adjustment filings ensure the correct maintenance of experience rating data and maintain employer account accuracy throughout each reporting year. Consistent compliance supports accurate audit reviews and proper benefit eligibility determinations.
When You’d Use California Form DE 9ADJ (2019)
Employers use Form DE 9ADJ to correct wage details, tax amounts, or employee information initially reported on required quarterly filings. This includes errors involving Wages Paid, tax rates, incorrect Social Security numbers, or adjustments linked to UI contributions. Employers must ensure that corrections match supporting records, such as the original Form DE 9, Form DE 9C, or Form W-2 documentation.
A DE 9ADJ filing applies only after submitting the initial DE 9 and DE 9C for the affected reporting period. Each quarter requires its own adjustment filing because the Employment Development Department processes quarter-specific corrections independently. Using e-Services for Business supports electronic filing and reduces delays associated with paper submissions that require a scannable version.
Key Rules or Details for 2019
Employers cannot request refunds for State Disability Insurance or Personal Income Tax withholdings unless employees receive corrected payments first. The Employment Development Department requires confirmation that workers received reimbursement before processing any employer refund request. Supporting documentation may include payroll records or other accepted proof required by the Employment Development Department.
Employers must submit a separate DE 9ADJ for each quarter requiring corrections, including changes involving wage adjustments or employee reporting. California Form DE 9 also requires accurate reporting of amounts submitted initially on the Quarterly Contribution Return. Employers referencing guidance from the California Employer’s Guide or related DE 44 instructions ensure compliant adjustment filing procedures.

Common Mistakes and How to Avoid Them
Filing delays occur when IRS submissions contain preventable administrative errors that interrupt established processing procedures. Clear identification of recurring issues supports compliance and improves resolution efficiency within IRS review workflows. Accurate preparation supports proper verification of Payroll Taxes and Wages Paid information during IRS reviews.
- Missing Signatures: Required signatures are often left blank on electronically filed forms, so each signature line must be checked before transmission.
- Mismatched EINs: EIN discrepancies appear when the number entered does not match IRS records, so the identifier must be verified before filing.
- Incomplete Attachments: Missing schedules or a required File Attachment prevent processing, so all supporting documents must accompany every submission.
- Late Payments: Payments received by the IRS after published deadlines must be remitted according to the posted schedule using the correct payment coupon.
- Incorrect Tax Period: The forms reflect the wrong reporting period, so the filer must confirm the period dates before completing the return.

What Happens After You File
The Employment Development Department reviews each DE 9ADJ filing to verify reported adjustments and confirm compatibility with previously submitted records. Processing timelines vary depending on the electronic filing or paper submission methods used by employers. Electronic filings generally process faster and reduce the volume of required correspondence.
Approved adjustments update employer account histories, including experience rating information connected with Unemployment Insurance contributions. Any resulting refunds are applied as credits or generate payments, depending on the employer's preference. When additional liabilities exist, submitting an Electronic Funds Transfer promptly helps prevent further interest charges.
