Voluntary service tax compliance scheme requires registration, specific declaration and acknowledgement forms, and prescribed payment procedures. The rules require that declarants be registered under the Service Tax Rules if not already registered; declarations must be made in Form VCES-1 with the authority issuing Form VCES-2 acknowledgement within seven working days. Tax dues and applicable interest must be paid to the Central Government as prescribed for service tax payments, with CENVAT credit prohibited for this purpose. Upon receipt of full payment details, the authority must issue Form VCES-3 acknowledgement of discharge within seven working days.
