Rule 4A of Service Tax Rules, 1995 prescribes that the taxable services shall be provided and input credit shall be distributed only on the basis of a bill, invoice or challan. Such bill, invoice or challan will also include documents used by service providers of banking services (such as pay-in-slip, debit credit advice etc.) and consignment note issued by goods transport agencies.
These documents should disclose the required information about service provided or agreed to be provided, service provider and receiver of service.
Rule 4A prescribes that taxable services are to be provided or credit has to be distributed on invoice, bill or challan only. Such documents should be serially numbered and shall contain -
(i) name, address and registration number of service provider, if applicable.
(ii) name and address of service receiver,
(iii) description and value of taxable service, and
(iv) details of service tax payment/payable thereon.
Further, under full reverse charge mechanism, a service provider should note to also mention that the entire amount of Service Tax on the invoice is payable by the service recipient under reverse charge
Hope the above clarifies the issue.
