If you find you reported taxes or wages incorrectly on a previously submitted report, you may submit a copy of that report with the corrections clearly indicated on it along with an explanation of the reason for the adjustment. Alternatively, you may download and complete an Adjustment Form (UC-522), or contact the Employer Accounting Unit.
Adjustments must be made to the quarterly report in which the error occurred; do not make an adjustment for a prior quarter on a current quarter's report. Do not attempt to correct a worker's over-reported wages by including a negative amount on a subsequent wage report; these amounts are read by the system as additional wages and could result in an overpayment of unemployment benefits or additional taxes due.
Correcting Names or Social Security Numbers on a Previously Submitted Report
You can make changes to a name or social security number by writing a letter, including the name reported/social security number reported previously, and the corrected name/social security number. Also provide the quarter(s) in which it was reported and be sure to include your Arizona unemployment tax account number.
Mail the letter to:
