What California Form DE 9ADJ (2022) Is For
California Form DE 9ADJ (2022) allows a liable employer to correct information previously reported on the Quarterly Contribution Return and Report of Wages. Employers use this form to adjust payroll taxes, unemployment taxes, and reported wage amounts. This process ensures the accuracy of employment tax records. The Employment Development Department relies on these corrections to maintain proper wage reports.
The form compares original figures with corrected amounts and calculates any resulting tax liability for the quarter. Corrections may involve Personal Income Tax, State Disability Insurance, Paid Family Leave, or other employment taxes. Employers may submit adjustments through e-Services for Business or by mailing paper returns using the addresses provided in the form instructions.
When You’d Use California Form DE 9ADJ (2022)
Employers use Form DE 9ADJ after finding errors on a previously filed DE 9 or DE 9C. Corrections may involve inaccurate wage totals, incorrect Social Security numbers, or issues affecting wage reports. The adjustment helps ensure accurate records, supporting future unemployment insurance tax calculations.
Employers may use this form only after submitting the original quarterly tax return for the quarter involved. Employers must complete the Quarterly Contribution Return before submitting any adjustments through e-Services for Business. California requires a separate form for each quarter, whether submitted electronically or through paper returns sent to the designated mailing address.
Key Rules or Details for 2022
The Employment Development Department requires employers to complete one Form DE 9ADJ for each affected quarter. Employers must report corrected positive figures only when adjusting previously submitted wage reports or payroll taxes. Refund requests involving Personal Income Tax or State Disability Insurance require employers to return amounts to employees before claiming credits.
Employers must attach Form W-2 amounts when requesting prior-year Personal Income Tax adjustments. Penalties may apply when corrected figures result in additional tax liability. Electronic filing through e-Services for Business aligns with the E-pay Mandate and supports timely processing compared with traditional paper submissions.
Step-by-Step (High Level)
- Step 1: The employer gathers the DE 9 and DE 9C, along with supporting payroll records. The employer compares wage reports, Social Security numbers, and Form W-2 amounts with the payroll ledger to confirm reported figures.
- Step 2: The employer lists each incorrect line, employee, and quarter requiring correction, and documents all affected entries. The employer notes any changes affecting Employment Training Tax, quarterly taxes, or tax liability calculations.
- Step 3: The employer completes Form DE 9ADJ by following the guidance in DE 44 and the official instructions. The employer enters original amounts, corrected amounts, and differences, and reconciles all figures with Form W-2 amounts.
- Step 4: The employer verifies the totals, business address, and account number before finalizing the figures. The employer confirms that all figures match payroll records and also match any related state or federal returns.
- Step 5: The employer submits Form DE 9ADJ through e-Services for Business or by using the paper filing option. The employer contacts the Taxpayer Assistance Center with any questions involving penalties or tax liability.

Common Mistakes and How to Avoid Them
Frequent submission problems arise when required information, signatures, or attachments are missing from employment-related tax returns. Identifying these documented issues improves accuracy and supports timely processing by the Internal Revenue Service or state agencies. Consistent compliance strengthens the reliability of wage reports and associated tax filings.
- Missing Required Signatures: Filers often submit DE 9 or DE 9C without signed declarations. Filers should review all signature fields carefully to ensure that each declaration is complete and accurate.
- Mismatched Employer Identification Numbers: EIN discrepancies occur when the entries on attached IRS forms do not match. Filers ensure compliance by confirming that every tax return contains identical identifiers.
- Omitted Form W-2 Attachments: Adjustments requiring Form W-2 amounts are sometimes filed without supporting documents. Filers maintain accuracy by including all the necessary attachments with each submission.
- Incorrect Payment Submission Dates: Payments are sometimes transmitted after the required business day deadline has passed. Filers maintain compliance when deposits are made on the day of business needed, as specified in the filing instructions.

What Happens After You File
The Employment Development Department reviews each DE 9ADJ submission to verify that corrected DE 9 and DE 9C information matches agency records. Processing times vary because reviewers assess wage reports, Form W-2 amounts, and related filings required for an accurate employment tax return. Employers must retain documentation showing corrected quarterly taxes and Social Security wages, as these records support inquiries from the Internal Revenue Service.
Approved adjustments may generate refunds when reported figures exceed required liabilities for the applicable quarter. E-Services for Business confirms this upon completion of processing. Additional tax liability requires prompt payment. The Taxpayer Assistance Center provides guidance on calculating interest resulting from corrected tax amounts. Employers must submit outstanding payments within specified business day deadlines to maintain compliance with California requirements under the E-pay Mandate rules.
