If a new determination by the Department, an administrative law judge, or the Workforce Appeals Board holds that the status of a worker or class of workers to which the individual belonged is that of employee for purposes of the Act, the employer is liable to pay unemployment contributions on all wages paid to workers in the class to which the individual belonged, from the beginning of the calendar quarter in which the new determination is made. In addition, the employer shall also be liable to pay contributions on any wages used by a claimant for purposes of establishing any claim for benefits affected by the new determination.
