CBIC Clarifies DIN Not Required on GST Portal Communications with Verifiable RFN

The Central Board of Indirect Taxes and Customs (CBIC) has issued a circular clarifying that a Document Identification Number (DIN) is not mandatory on communications that are generated and transmitted through the GST portal, as long as they contain a verifiable Reference File Number (RFN). This measure is aimed at streamlining compliance and reducing procedural complexities. The CBIC explained that the primary purpose of the DIN system is to ensure the authenticity and traceability of offline, manual communications from the tax department. Since communications issued through the GST portal are inherently system-generated and have a unique RFN, their trail is already officially recorded and verifiable. Therefore, insisting on a separate DIN for such online communications is redundant. This move provides clarity for both taxpayers and tax officials, ensuring that the focus remains on the substance of the communication rather than on procedural technicalities.
