Every service user in this state is liable for the surcharges until they have been paid to this state, except that payment to a service supplier registered under this part is sufficient to relieve the service user from further liability for the surcharges.

Any surcharge collected from

a service user that has not been remitted to the department shall be deemed a debt owed to the state by the person required to collect and remit that surcharge.
