What California Form DE 9ADJ (2020) Is For
California Form DE 9ADJ (2020) corrects previously filed DE 9 and DE 9C reports submitted to the California Employment Development Department for quarterly payroll adjustments. Employers use this application form to update wages, employee names, Social Security numbers, or employment tax details that were initially reported. It also resolves errors involving unemployment insurance tax amounts, Employment Training Tax calculations, or State Disability Insurance reporting.
This paper form supports accurate reconciliation when employers identify discrepancies after filing their initial quarterly information. It works in conjunction with DE 9 forms to ensure that corrected wages reflect the proper payment status and benefits paid. The California Employment Development Department relies on these adjustments to preserve accurate unemployment insurance program records for eligible employers.
When You’d Use California Form DE 9ADJ (2020)
Employers file this form when wage information requires correction after reviewing payroll records for a closed quarter. Adjustments may involve inaccurate employee wages, incorrect withholding entries, or misreported Personal Income Tax amounts. Employers also use this form after identifying issues that affect their unemployment benefits reporting obligations.
Late amendments occur when errors appear during internal audits or after receiving notices of unemployment insurance from California’s unemployment department. This includes corrections linked to unemployment taxes, benefit reimbursements, or domestic employment classifications. The form applies whenever employers must address mistakes without having to refile the original tax forms completely.
Key Rules or Details for 2020
Refund claims for overpayments must follow strict filing requirements established by the State of California for quarterly adjustments. Employers must submit separate forms for each corrected quarter, regardless of the complexity of the issue. Credits involving employee withholdings apply only after employees receive reimbursements for incorrect deductions.
The Employment Development Department prohibits the reporting of annual totals on this form because quarterly reporting is necessary to support the accuracy of unemployment insurance benefits. Adjustments involving State Disability Insurance require employers to verify refund eligibility before requesting account credits. Employers must calculate penalties and interest accurately for amounts owed on amended filings.

Common Mistakes and How to Avoid Them
Submission issues frequently arise because filers overlook specific procedural requirements that affect state payroll reporting accuracy. Identifying these recurring errors strengthens compliance and supports smoother processing within California’s unemployment agency systems. Clear, complete filings help prevent correction requests that delay updates to employer accounts.
- Omitted Signatures: Adjustment forms are returned when signature fields are left blank, and filers must verify all required signatures before sending the application form.
- Incorrect Employer Identification Numbers: Mismatched identifiers occur when employer numbers differ from those in Internal Revenue Service records, and filers must verify accurate entries on all tax forms.
- Missing Wage Attachments: DE 9 forms are delayed when Form 1099G or required wage schedules are excluded, and filers must include all necessary attachments for amended filings.
- Incorrect Prior Quarter Figures: Errors occur when corrected amounts replace originally reported totals, and filers must enter prior figures exactly as initially filed.
- Improper Employee Detail Updates: Wage corrections fail when employee names or Social Security numbers are incomplete, and filers must verify these fields before submitting corrections.
What Happens After You File
The Employment Development Department processes forms in the order received and verifies corrected information against previously submitted records. Simple wage adjustments typically process more quickly than claims involving unemployment insurance benefits. Incomplete filings result in returned forms that require additional documentation.
Refunds are applied to employer accounts, except when outstanding balances exist for prior assessments or unemployment claims that have not been settled. Additional taxes, including penalties and interest, are accrued in accordance with state rules. Corrected information updates employee wage histories supporting unemployment insurance program eligibility.
