Legal Significance of Document Identification Number (DIN) in GST: A Shield Against Invalid Notices [Find Draft Reply Format Here]

The introduction of the Document Identification Number (DIN) by the Central Board of Indirect Taxes and Customs (CBIC) was a landmark step in ensuring transparency, accountability, and authenticity in tax administration. This mechanism, which came into force through CBIC Circular No. 122/41/2019-GST dated 5th November 2019, mandates that all communications—such as notices, summons, letters, and orders—issued by GST officers must bear a system-generated DIN. However, several taxpayers continue to receive communications, including Show Cause Notices (SCNs), without the mandatory DIN, raising serious legal and procedural concerns.

Understanding DIN and Its Purpose

The Document Identification Number (DIN) is a unique number generated for each communication sent by the tax authorities to taxpayers. It serves three key purposes:

1. Authenticity: It ensures that the communication is issued by a legitimate authority.
2. Traceability: It allows both the taxpayer and the department to track the document and its issuance details.
3. Transparency:
   It minimizes the possibility of misuse or harassment by ensuring official traceable communication only.

DIN is applicable across both the Goods and Services Tax (GST) and Income Tax regimes. The Ministry of Finance, in various public communications, has reiterated the DIN’s mandatory nature and its importance in improving the governance framework of Indian tax administration.

Circular No. 122/41/2019-GST (5th November 2019):

This CBIC circular states unequivocally that:

“Any specified communication which does not bear the electronically generated DIN shall be treated as invalid and shall be deemed to have never been issued.”

This means that any notice or correspondence not containing a DIN is void ab initio and lacks any legal force.

Circular No. 128/47/2019-GST (23rd December 2019):

This follow-up circular further reinforced the mandatory use of DIN and laid down exceptions (e.g., technical issues) that must be specifically recorded in the official file and the communication.

Ministry-Level Affirmation

The then Finance Minister, Smt. Nirmala Sitharaman, via a tweet dated 1st October 2019, publicly declared the launch of DIN and clarified that all communications without it shall be deemed “never issued.” Additionally, a press release by the Ministry of Finance dated 7th November 2019 confirmed that:

“Any communication issued without a DIN shall be treated as invalid and shall be deemed never to have been issued.”

This high-level affirmation provides taxpayers with a robust legal shield in cases where DIN is absent.

What Happens When DIN is Missing in a GST Notice?

If a Show Cause Notice (SCN) is issued without a DIN:

• It does not carry legal validity.
• It cannot be acted upon by the department to impose penalties or liabilities.
• The taxpayer is not legally obligated to respond, as the SCN is considered non-existent in the eyes of law.

Remedies for Taxpayers

1. Raise an Objection Promptly: Taxpayers should promptly respond, pointing out the lack of DIN and citing the relevant CBIC circulars.
2. Seek Withdrawal of the Defective Notice: A formal request may be made for withdrawal of the invalid SCN and issuance of a fresh, valid one.
3. Maintain Written Record: Ensure that all communications and objections are recorded in writing with acknowledgments for future legal defense.

Judicial Recognition and Precedents

Although there is limited jurisprudence directly on DIN in GST, the principle of mandatory procedural compliance has been well established in Indian administrative and tax law. Courts have consistently held that where procedural safeguards are violated, such proceedings may be quashed.

The enforceability of departmental circulars under Article 226 has been upheld, and taxpayers can approach High Courts to challenge DIN-less notices.
