Service tax registration requires applicants to furnish PAN, entity details, premises addresses and select applicable taxable services. Application under Section 69 requires applicants to indicate new registration or amendment, provide name, address and PAN, identify legal constitution and principal persons, and specify category of registrant (service provider/recipient or Input Service Distributor). Applicants must state whether registration is for a single premise or centralized registration and furnish detailed premises addresses. The form mandates identification of the office paying service tax under centralized billing, selection of taxable services from the Annexure, and completion of a declaration certifying accuracy with provision for issuance/acknowledgement by the tax authority.
