(1) Within a reasonable time after the computation date each employer shall be notified of the employer's rate of contribution as determined for the succeeding rate year and factors used in the calculation. Beginning with rate year 2005, the notice must include the amount of the contribution rate that is attributable to each component of the rate under RCW
50.29.025(1).
(2) Any employer dissatisfied with the benefit charges made to the employer's account for the twelve-month period immediately preceding the computation date or with his or her determined rate may file a request for review and redetermination with the commissioner within thirty days of the mailing of the notice to the employer, showing the reason for such request. Should such request for review and redetermination be denied, the employer may, within thirty days of the mailing of such notice of denial, file with the appeal tribunal a petition for hearing which shall be heard in the same manner as a petition for denial of refund. The appellate procedure prescribed by this title for further appeal shall apply to all denials of review and redetermination under this section.
