Wyo. Stat. § 11-50-107: Refund.

(a) Any person who has paid any assessment as provided in this act is entitled to a prompt refund of the contribution from the commission upon request. A claim for a refund shall be made to the commission not less than thirty (30) nor more than ninety (90) days from the date of the sale upon which the assessment was based. The claim shall be made on a form prescribed and furnished by the commission. No assessment paid by a handler is refundable under this section unless the grower has also claimed a refund under this section for the matching portion of the assessment.

(b) Before processing any claim for refund under this section, the commission may require any additional information or affirmation under penalty of perjury it deems necessary to determine the validity of the claim.
