2005 Arizona Revised Statutes - Revised Statutes §23-742  Adjustment or refund of contribution; limitation

A. Not later than three years after the date on which any contribution or interest on a contribution becomes due, an employer who has paid the contribution or interest may apply for an adjustment of the contribution or interest in connection with subsequent contribution payments, or for a refund of the contribution or interest in the event the adjustment cannot be made. If the department finds the contribution or interest, or any part of the contribution or interest, was erroneously collected, it shall allow the employer to make an adjustment, without interest, in connection with subsequent contribution payments, or if the adjustment cannot be made the department shall refund the amount, without interest, from the fund into which payments were made. For like cause and within the same period, the adjustment or refund may be made on the initiative of the department.

B. Any refund or adjustment of contributions erroneously paid shall be reduced by the sum of any benefit overpayments which are attributable to the wages on which contributions are to be refunded or adjusted, except that a reduction shall not be made if it is shown to the satisfaction of the department that such contributions were required to be paid due to the fault, mistake or omission of the department.
