Adjustments to Previously Filed Reports

To adjust previously reported amounts or data for individual workers and the overall quarterly totals (total wages, excess wages, taxable wages, tax), an employer may file an adjustment request online or by paper.

• Online: File an adjustment request through the Division’s Internet reporting system, USTAR. Registered users may select the Amend option under the Report Center tab.

• Paper: Download and complete the Contribution and Wage Adjustment Report (MODES-4A). Mail the completed form to: Division of Employment Security, Attn: Employer Accounts Unit, PO Box 59, Jefferson City MO 65104, or fax to (573) 751-0861.

• Telephone: Call (573) 751-3329.

A claim for refund or credit must be filed within three years of the last timely filing date of the quarter being adjusted.
