Deemed registration applies when the local superintendent delays issuance, but not to centralized registration by the Commissioner.
Failure of the Superintendent of Central Excise to issue Form ST-2 within seven days triggers deemed registration; that deeming provision applies only to registrations by the Superintendent and not to centralized registrations granted by the Commissioner, where no statutory time limit exists. Registration must nevertheless be granted within a reasonable time, and administrative circulars treating seven days as reasonable impose directory guidance and accountability but do not create deemed registration for the Commissioner.

Registration refusal prohibited: complete service tax applications must be accepted and authorities cannot register suo moto.
A complete and properly filled application in Form ST-1 and/or ST-2 must be accepted; there is no statutory power under the Finance Act, 1994 or the Service Tax Rules, 1994 for the Superintendent or the Commissioner to refuse registration, nor to grant registration suo moto. Registration is confined to the category specified in the application, and non-alignment with the correct category may attract recovery or penal proceedings.

Surrender of service tax registration required on cessation of taxable services; cancellation follows after dues are cleared and documents submitted.
Surrender of the registration certificate is mandatory upon cessation of taxable services and must be submitted to the Superintendent, who ensures all dues are paid before cancelling registration. No prescribed format exists; a simple application is acceptable. A trade notice lists common reasons for surrender and requires an application and undertaking, copies of recent ST-3 returns (up to six), profit & loss accounts and balance sheets (up to three years) or income tax returns or bank statements if unavailable, and disclosure of pending show-cause notices, confirmed demands, court cases and audits; waiver of penalty may be applied where returns were not filed but turnover is below the exemption limit.

Service tax registration non-transferability requires transferee to obtain immediate fresh registration certificate upon business transfer.
Service tax registration certificates are not transferable under rule 4(6) of the Service Tax Rules, 1994; upon transfer of business the transferee must obtain a fresh certificate and is to be treated as a new registrant rather than a continuation or renewal of the transferor's registration.

Single premises registration requires online ST 1 filing, two day grant, and mandatory PAN with document verification.
Registration for a single premises must be filed online via ACES using Form ST-1; registration is to be granted online within two days and electronic payment enabled. Within seven days of filing the applicant must post self attested documents to the Division for verification. PAN is mandatory for non government applicants; e mail and mobile number are compulsory. Required documents include PAN copy, identity/photograph of filer, proof of possession of premises, main bank account details, memorandum/articles or directors list, authorization for the filer, and existing business transaction numbers from other government agencies.
