Serviceman
Where a serviceman has made a
sale of service and has paid the applicable Service Occupation Tax to the
Department, and then subsequently refunds to his customer the amount paid by
the customer for the service and where such refund is the result of the return
of tangible personal property previously transferred to the customer as an
incident to that sale of service, the serviceman may take a deduction for the
returned merchandise on his monthly return.
