Introduction

The service of notices under Section 169 of the Central Goods and Services Tax (CGST) Act, 2017, is a critical aspect of tax administration. This article explores the legal requirements for notice service, focusing on the sufficiency and effectiveness of service through the GST common portal, and examines key judgments from the Madras High Court.

Main Points and Key Messages

1. Section 169 of the CGST Act: This section outlines various modes of service, including personal delivery, registered post, email, and publication on the GST portal or in a newspaper. The Madras High Court has provided nuanced interpretations of these provisions, emphasizing the importance of natural justice.

2. Judicial Interpretations: The Madras High Court has delivered several judgments that shape the understanding of notice service under GST. These rulings highlight the tension between legal sufficiency and practical effectiveness.

3. Sufficiency vs. Effectiveness: Recent judgments attempt to reconcile divergent views by distinguishing between “sufficient” (legally valid) and “effective” service. This distinction implies a practical obligation on authorities to ensure actual awareness on the part of the taxpayer.

Body Section 169 of the CGST Act

Section 169 enumerates various modes of service, including personal delivery, registered post, email, and publication on the GST portal or in a newspaper. The prescribed modes are alternative and non-sequential, suggesting that any single method constitutes valid service. However, recent judgments from the Madras High Court reveal a nuanced interpretation of these provisions.

Judicial Interpretations

The Madras High Court has delivered several key judgments that shape the understanding of notice service under GST. In Udumalpet Sarvodaya Sangham v. The Authority, the court held that reliance solely on the GST portal does not fulfill the statutory requirements of Section 169. The judgment emphasized that taxpayers must be informed through effective channels to ensure their fair participation in proceedings.

Conversely, in M/s.Poomika Infra Developers v. State Tax Officer, the court held that service by making it available on the common portal is a valid mode of service. The court concluded that the GST portal constitutes a “designated computer resource” for both the Department and the taxable person.

Reconciling the Views

Justice Krishnan Ramasamy’s ruling attempts to reconcile these positions by distinguishing between “sufficient” and “effective” service. The court held that while service via the GST portal is legally sufficient, tax authorities also bear a responsibility to ensure practical effectiveness. This introduces a practical obligation on authorities to ensure actual awareness if portal service proves unresponsive.

Motive of the Law and pronoucement

The evolving judicial interpretations of Section 169 highlight the interplay between statutory provisions, technological advancements, and fundamental legal principles. While portal service is legally sufficient, authorities should adopt a multi-modal approach to ensure effective communication and uphold natural justice. Taxpayers must diligently monitor the GST portal and maintain updated contact information to avoid adverse ex parte orders.

Ultimately, the digital transformation of tax administration must balance efficiency with the taxpayer’s fundamental right to due process. A definitive ruling from the Supreme Court or legislative amendments to Section 169 would provide greater clarity and uniformity in the application of the law.

The Supreme Court issued a directive to the Union of India concerning the implementation of an effective Document Identification Number (DIN) in the following case:

1.Case Title:

Pradeep Goyal vs. Union of India & Ors. ​ Writ Petition (Civil) No. ​ 320 of 2022 ​

2. Summary of Facts:

The petitioner, Pradeep Goyal, a Chartered Accountant, filed a Public Interest Litigation under Article 32 of the Constitution of India. ​ He sought the implementation of a system for electronic (digital) generation of a Document Identification Number (DIN) for all communications sent by State Tax Officers to taxpayers and other concerned persons. ​ The petitioner argued that such a system would enhance transparency and accountability in indirect tax administration, prevent abuse by departmental officers, and align with the government’s objective of better serving honest taxpayers. ​ While the Central Government implemented the DIN system for the Central Board of Direct Taxes (CBDT) in 2019, only two states—Karnataka and Kerala—had adopted the system for indirect tax administration. ​

3. Key Issues:

  • Whether the implementation of a DIN system for communications by State Tax Officers is necessary to ensure transparency and accountability in indirect tax administration.
  • Whether the GST Council should issue recommendations or advisories to states for implementing the DIN system.
  • Whether the Central Government should introduce a centralized DIN system for the entire country.

4. Decision/Outcome:

The Supreme Court disposed of the writ petition by directing the Union of India and the GST Council to issue advisories, instructions, or recommendations to all states regarding the implementation of the DIN system in indirect tax administration. ​ The Court also urged the states to consider implementing the DIN system at the earliest to enhance transparency and accountability.

Now the CBIC has introduced RFN in the Place of DIN

 CBIC Clarifies DIN Requirement for GST Communications

The Central Board of Indirect Taxes and Customs (CBIC) has issued Circular No. 249/06/2025-GST DT: 09-06-2025, bringing a crucial update on the Document Identification Number (DIN) requirement for GST-related communications.

Key Takeaways:

  • RFN vs. DIN: Documents generated via the GST common portal already carry a Reference Number (RFN), which is verifiable online. This eliminates the need for quoting DIN separately.
  • Legal Backing: Section 169(1)(d) of the CGST Act, 2017 mandates that decisions, orders, summons, and notices be served via the common portal, ensuring authenticity.
  • Compliance with Rule 142: CBIC reiterates that Show Cause Notices (Form GST DRC-01) and Order-in-Original summaries (Form GST DRC-07) must be electronically served on the portal.
  • Modification of Previous Circulars: Circulars 122/41/2019-GST and 128/47/2019-GST are now modified to reflect this change, streamlining communication protocols.

Why This Matters: This move enhances efficiency, transparency, and accountability in GST communications, reducing redundancy and ensuring seamless verification through the GST portal.

Author’s Concluding Remarks:  Upon a comprehensive analysis of Section 169 of the CGST Act, relevant judicial pronouncements, and the implementation of the Document Identification Number (DIN) and subsequently the Reference Number (RFN), it is evident that the underlying objective is to ensure effective communication between the tax authorities and taxpayers. The principle of natural justice mandates that any notice or communication issued by the authorities must not only be dispatched in accordance with the prescribed modes under Section 169 but must also be effectively served and brought to the notice of the taxpayer. Mere issuance of a notice does not suffice; the essence lies in its proper and timely delivery. Only then can the true spirit of the law be upheld, ensuring transparency, accountability, and fairness in tax administration.
