Utah Admin. Code 994-207-106
If the time spent on commission selling is part-time because of limits imposed by the limited geographical area, limited clientele, or limited products, the claimant could, upon meeting all other provisions of the Act, be allowed benefits.
It is necessary to distribute the income from commission sales over the period of time it took to earn the commission. The income should be reported during the week in which the sale is made and not when the payment is received. If it is not possible to determine the exact amount of the commission, an estimate should be made and if the estimate is later determined to be wrong, the claimant should immediately report to the Department to receive assistance in making adjustments. Failure to report under estimates may result in claimant fault overpayments and a disqualification under the fraud provisions of the Act.
